Application All vessels
Responsibility Master Navigating Officers Watch Keepers
1.1
INTRODUCTION TO BRIDGE TEAM MANAGEMENT
Bridge Team Management is the interaction of team members which allows the Team to adapt to and fulfil Team roles that have been identified and assigned. Bridge Team Management is the use of all physical and personnel assets and the creation of an environment to maximise their effectiveness. Thome requires that all company vessels carry the publication by the International Chamber of Shipping, Bridge Procedures Guide. Thome requires that all vessels be navigated in accordance with the Bridge Team Management Principles contained within. Bridge Team Management is a concept that when accepted by the Mariner is the single most important method for eliminating “one person error”. The term Bridge Team Management is not a navigational skill or management act by one person, nor should it be confused or interpreted as navigation by committee. Bridge Team Management is the interaction of team members which allows the Team to adapt to and fulfil Team roles that have been identified and assigned.
1.2
GOALS OF BRIDGE TEAM MANAGEMENT
The primary goal of Bridge Team Management is the elimination of “one person errors.” All members of the Bridge Team are to keep themselves aware of all vessel operations. Pilots are considered team members and they play a critical role on the Bridge. It is the responsibility of the Bridge Team to assist the pilot whenever practical. Thome's Bridge Team is expected to achieve these goals by the effective use of: •
Appropriate Steaming Watch Conditions and assignment of tasks to Team members
•
All Bridge equipment and personnel
•
Manoeuvring characteristics of the vessel
•
Management of stress and distractions
•
Creation of a Team environment
•
Communications

MANAGEMENT OF STRESS AND DISTRACTIONS
Each Bridge Team member should be conscious of the inherent stress and distractions in Bridge situations. Stress affects each individual differently. Stress levels may increase or decrease our effectiveness in performing our tasks on the Bridge. Team members need to be aware of how stress affects the other Team members. Bridge tasks may need to be reassigned or changed, depending on the stress levels and the personnel involved. Tasks that are stressful to one person may not be stressful to another. Signs of stress include: •
Difficulty in thinking
•
Inattention
•
Slow reactions
•
Procedural violations or skipping procedures
•
Muscle aches
•
Chills
•
Pale complexion
•
Dull or bloodshot eyes
The inability to deal with distractions and prioritise is often an indication that situational awareness is breaking down. Distractions can be caused by stress, excessive work load, fatigue, emergency conditions, and all too often inattention to detail. Assigning tasks is one way of not allowing stress and distractions to disrupt the effectiveness of the Bridge Team.
1.4
CREATING A TEAM ENVIRONMENT
It is the responsibility of all Team members to create an environment conducive to the free exchange of observations and information. Masters shall ensure that all Team members participate in Bridge Operations and dispel any possible belief of a Team member that his/her information may be irrelevant, redundant, or obvious. Masters are to ensure that: •
Individual team members are well aware of their duties and responsibilities as well as the chain of command when the Pilot is on board
•
They are also to clarify without doubt, the limitation of the Pilots authority whilst he is on board and working as part of the bridge team
•
A discipline within their Bridge Teams is established so that no member hesitates to question the decision/command of anyone else
•
To bring about an awareness in their Bridge Teams, of the ‘Human Factor’ and errors arising from the same

STANDARD PROTOCOL FOR VHF RADIO USE:
All Deck officers shall utilise the IMO Recommended Phraseology for Maritime Communications and comply with FCC regulations i.e. Use of call signs. The IMO Book is supplied to all Managed vessels.
1.7
STANDARD ORDERS TO THE HELM
One of the barriers to good communication is the use of vague or unfamiliar language. For this reason, all Masters and Deck Officers shall use the Standard Orders to the Helm. The helmsman is an important part of the Bridge team. Deck Officers shall train and ensure that all helmsmen clearly understand the Standard Orders to the Helm. It must be understood that it is the responsibility of the Bridge Watch to assist Pilots with the use of Standard Orders to the Helm. Figure 1-1 Standard Orders to the Helm Order
Meaning and Action Required
Midships
Rudder to be held in the fore and aft position
Port/Stbd five, ten, twenty
5 degrees, 10 degrees, or 20 degrees Port or Stbd rudder to be held
Hard Starboard / Port
Rudder to be held fully over Starboard or Port
Ease to five, ten, twenty
Reduce the amount of rudder to 5 degrees, 10 degrees or 20 degrees and hold.
Steady or Steady as she goes
Steer a course on the compass heading indicated at the time of the order. Helmsman is to call out the compass heading (in three digits) upon receiving the order. When the ship is steady on that heading the helmsman is to call out “Steady on XXX” (course in three digits)
Nothing to the Port of XXX (course)
Use appropriate rudder in either direction to keep the vessel on or to the starboard of a given course but nothing to the port.
When the conning officer requires a course to be steered by compass, the direction in which he wants the wheel turned shall be stated followed by each numeral being said separately (course in three digits).

On receipt of an order to steer a course, the helmsman should repeat the order and bring the ship around steadily to the course ordered calling out the heading every ten degrees in the process. When the ship is steady on the course ordered, the helmsman is to call out: "Steady on XXX" (course in three digits). The conning officer should then acknowledge the helmsman's call out with: “Very Well,” or “182 Very Well,” etc.
1.8
BRIDGE TEAM / PILOT EXCHANGE
The Pilot is an important part of the Bridge Team. It is the responsibility of the Master and the Watch Officers to incorporate the Pilot into the Bridge Team. The Bridge Team / Pilot exchange needs to take place in a timely manner and at an appropriate pace. In conjunction with the Master / Pilot Exchange Card, a copy of the Passage Plan shall be made available to the Bridge Team / Pilot and discussed at an appropriate time. While discussing the Passage Plan, special reference should be made to the following: •
Parallel Indexing techniques
•
Alteration points to be marked off with bearings/ranges of terrestrial targets and/or geographical co-ordinates
•
“No Go” areas to be clearly marked off taking into account the draught of the v/l, the proximity of navigational hazards and the possibility of other vessels in the vicinity
•
Means of position fixing are to be in strict conformance with the Passage Plan. It has been noted in instances that the Passage Plan reflects position fixing means by way of GPS, terrestrial as well as celestial observations. However, the only means used have been GPS fixes. In other instances, terrestrial fixes are plotted using only one bearing and range where a fix constitutes at least three reference lines to make a ‘Cocked Hat’
•
Frequency of Position fixing to be at intervals not exceeding that as indicated in the Passage Plan. Repeated non-conformance is evident here also
•
The importance of inserting the T&P notices on relevant Charts
•
The importance of filing and keeping logs of T&P notices and Navtex messages segregated for Navigation warnings and Weather messages)
•
The importance of using all navigation equipment applicable in the prevailing circumstances and conditions with special reference to marking off Echo sounders and course recorders at relevant times such as E.O.P., Pilot boarding, etc.

OPERATIONAL AND EMERGENCY CHECKLISTS
Checklists required to be completed: •
prior to getting underway
•
changing over the watch (underway or at anchor)
•
arrival
•
after daily (noon) Bridge tests
A checklist is a written memory aid used to accomplish a series of tasks. A checklist is not a substitute for thorough knowledge of the ship or procedures. The use of a check list prior to port entry/departure, change of the watch, and for the daily (noon) Bridge check is required. The completed check lists must be signed and retained aboard the vessel for one year. Benefits of a checklist: •
Focus attention on the task at hand
•
Help establish priorities
•
Serve as an aid against failure of human memory, especially during periods of stress and emergency
•
Help to balance workloads
•
Eliminate guesswork and substitute standard procedures

2.1
PASSAGE PLANNING
Use of a Passage Plan is compulsory. The Purpose of a Passage Plan is to establish a navigational procedure to pre-plan a vessel’s route and monitor its progress along the route. A Passage Plan is a means of sharing information with all Bridge Team members, including the pilot. The Passage Plan also incorporates a system of procedures and checks to guard against "one person errors." •

•
The aim of the bridge team is safe passage for the ship for each of its voyages. To achieve this each passage needs careful preparation, planning, execution and monitoring
•
Upon receipt of the voyage orders, the Navigating Officer, under the guidance of the Master, is to plan the voyage by the most expeditious route bearing in mind that the safety of the vessel is of the prime importance
•
The Master exercises management control over the passage plan by approving the plan before commencing the intended voyage
2.2
PREPARATION
The charts and publications for the intended voyage are to be on board and corrected up to the latest Notice to Mariners, including temporary (T) and preliminary (P) notices and any radio navigational warnings (Navtex, EGC, etc.). The Master is to ensure that the declaration as stated in Checklist A of the TSM 001 – Passage Plan (Master’s declaration) is complied with before intended voyage. If the charts for the intended voyage are not available onboard, the Master should contact the Marine & HSSEQ Department or the Marine Manager. At the same time, the following measures are to be taken: •
Try obtaining the charts from the departure port or via an agent enroute if possible. Consider the possibility of obtaining the charts at the anchorage before proceeding in bound to berth

Indian Charts In February 2013, the Gujarat Maritime Board (GMB) issued a notice that Indian charts were to be kept on board when entering into the Gujarat Coast. So far there is no penalty for not having the charts on board, but that could change after 1st June 2013. Please refer to HSSEQ Circular 21 – 2013 for further guidance.
2.3
PLANNING
Having made the fullest preparation, using all available information, the Navigating Officer will make a detailed passage plan. This plan must cover the whole passage i.e berth to berth, including all the waters where a pilot will be onboard. The formulation of the plan will involve the following: •
Plot the intended passage on the appropriate charts and mark clearly, on the largest scale charts available, all the areas of danger and the intended track, taking into account all the margins of allowable error. Where appropriate, due regard should be given to the need for an advance warning on one chart of the existence of a navigational hazard upon transfer to the next. The planned track should be plotted to clear hazards at as safe a distance as circumstances allow. A greater distance should always be accepted in preference to a shorter, more hazardous route. The possibility of machinery breakdown at a critical moment must not be overlooked
•
Indicate clearly, in 360 degree notation, the true direction of the planned track on all charts
•
Mark on the chart any transit marks, clearing bearings or clearing ranges, which may be used to advantage
•
Decide upon the key elements of the plan, these should include but not be limited to: o
Safe speed having regard to the manoeuvring characteristics of the ship and, in ships restricted by draft, due allowance for reduction of draft due to squat and heel effect when turning
o
Speed alterations necessary to achieve desired ETA’s en-route, e.g. where there may be limitations on night passages, tidal restrictions etc.
o
Positions where a change in machinery status is required
o
Course alteration points with wheel over positions - where appropriate, on large scale charts taking into account the ships turning circle at the planned speed and the effect of any tidal stream and current on the ships movement during the turn
o
Minimum clearance required under the keel in critical areas
o
Air draft clearance required, as appropriate
o
Points where accuracy of position fixing is critical and the primary and secondary methods by which such positions must be obtained for maximum reliability
o
Contingency arrangements i.e. alternative routes, emergency anchoring etc. in the event of an emergency
o
Point of no return
In addition to noting the details of the plan onto the “Passage Plan” forms the prominent details of the plan should be marked on the charts.

SPOS, a weather forecasting software, has been rolled out to the majority of our fleet vessels to assist our Masters in the consideration of weather conditions, with up to date weather forecasts received twice a day by e-mail direct into the program. Within the vessels passage plan the Master must ensure the 2/O utilises this medium to support his passage plan, both in the attempt to prevent weather related incidents onboard while maximising weather conditions for speed efficiencies. This software tool does not relieve any watch keeping officer from his duty in ensuring all practical means of monitoring the vessels safe position and track at all times.
Particularly sensitive sea areas When an area is approved as a particularly sensitive sea area, specific measures can be used to control the maritime activities in that area, such as routeing measures, strict application of MARPOL discharge and equipment requirements for ships, such as oil tankers; and installation of Vessel Traffic Services (VTS).
List of adopted PSSAs The following PSSAS have been designated: •
The Great Barrier Reef, Australia (designated a PSSA in 1990)
•
The Sabana-Camagüey Archipelago in Cuba (1997)
•
Malpelo Island, Colombia (2002)
•
The sea around the Florida Keys, United States (2002)
•
The Wadden Sea, Denmark, Germany, Netherlands (2002)
•
Paracas National Reserve, Peru (2003)
•
Western European Waters (2004)
•
Extension of the existing Great Barrier Reef PSSA to include the Torres Strait (proposed by Australia and Papua New Guinea) (2005)
•
Canary Islands, Spain (2005)
•
The Galapagos Archipelago, Ecuador (2005)
•
The Baltic Sea area, Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland and Sweden (2005)
•
The Papahānaumokuākea Marine National Monument, United States (2007)
•
The Strait of Bonifacio, France and Italy (2011)
Ships routeing measures to protect PSSAs A PSSA can be protected by ships routing measures – such as an area to be avoided: an area within defined limits in which either navigation is particularly hazardous or it is exceptionally important to avoid casualties and which should be avoided by all ships, or by certain classes of ships. The IMO Publication Ships' Routeing includes General provisions on ships' routeing, first adopted by IMO in 1973, and subsequently amended over the years, which are aimed at standardizing the design, development, charted presentation and use of routeing measures adopted by IMO.

The numbers of all charts to be used during the voyage shall be entered, followed by NZ for New Zealand, Aus for Australia, etc.
•
Navigational information between waypoints to be completed only when there is significant information between waypoints. If the additional information permits, more waypoints may be entered on one page (e.g. Ocean Passages, Great Circle, etc.). If more pages than available in this plan are needed, loose pages may be inserted
•
Parallel indexing information o
2.6
Whenever possible, parallel indexing must be used as an aid to navigation, not only to keep the vessel on her intended track, but also for accurate planning of course alterations. Officers must compare the intended course alteration against the actual track in order to become fully familiar with the behaviour of the vessel
MONITORING
The close and continuous monitoring of the ship’s progress along the pre-planned track is essential for the safe conduct of the passage. If the officer of the watch is ever in any doubt as to the position of the ship, he must at once call the Master and, if necessary, take whatever action he may think necessary for the safety of the ship.

The performance of the navigational equipment should be checked prior to sailing, prior to entering restricted or hazardous waters and at regular intervals during the passage. Advantage should be taken of all navigational equipment with which the ship is fitted for monitoring, bearing in mind the following points: •
Visual bearings are usually the most accurate means of position fixing
•
Every fix should, if possible, be based on at least three position lines
•
Transit marks, clearing ranges and clearing bearings can be of great assistance
•
When checking fixes, use systems which are based upon different data
•
Positions obtained by navigational aids should be checked by visual means
•
The value of the echo sounder as a navigational aid
•
Buoys should not be relied upon for fixing but may be used for guidance when shore marks are difficult to distinguish visually
•
The functioning and correct readings of instruments used
•
The frequency with which the position is required to be fixed
•
Radar can be used to advantage in monitoring the position of the ship by the use of parallel indexing techniques. Parallel indexing, as a simple and most effective way of continuously monitoring the ship’s progress in restricted waters, can be used in any situation where radar conspicuous navigation marks are available o
2.7
Parallel Indexing is compulsory when in coastal navigation
COMPANY REVIEW OF PASSAGE PLAN.
Company should carry out Radom sampling of the Passage plan and UKC at regular intervals. These should be also checked and verified during the Superintendents visits and during the internal audit. The main purpose for checking is to confirm compliance with Company’s requirement. Confirm that the relevant sailing directions, available port information been studied and information contained therein been given consideration when planning the passage, whether the current / tidal stream atlases been consulted, whether the charted aids to navigation been studied and highlighted for landfall and position monitoring purposes, whether the requirements regarding traffic separation schemes / vessel traffic routing services Particularly Sensitive Sea Areas (PSSA's), Archipelagic Sea Lanes (ASL) been considered when planning the passage , whether the planned route takes into account applicable Environmental protection measures, whether study of pilot boarding areas and anchorages been made.

3.1
BRIDGE WATCH CONDITIONS
Bridge manning requirements vary substantially depending upon location, traffic density and weather conditions. This section describes how underway Bridge Watches should be manned, and the duties of watch officers and crew members involved for each different Bridge Watch set. The Pilot is not considered part of the vessel’s complement. However he may be considered the 2nd or the 3rd licensed officer on the Bridge in pilotage waters. These are a minimum and should be increased if considered necessary by the master. •
The Master has a responsibility to set the proper Bridge Watch and to ensure a proper vessel lookout
•
A change of Bridge Watch condition (i.e., from Bridge Watch I to Bridge Watch II) does not automatically change the Con. Until the senior officer orders a change, the con will remain with the Deck Watch Officer who had it before the change of Bridge Watch condition. Any change of con must be logged in the Deck Logbook
•
All personnel, including officers and unlicensed seamen who may be assigned to any duty station in any Bridge Watch, shall understand fully the duties expected of them. It is the Master's responsibility to ensure that all officers and crew members are properly trained. All watch personnel shall be entered in the deck log book
•
When underway, Bridge Watches shall be set at the Master's direction and discretion according to prevailing conditions o

At any Time When the Following Conditions Exist: High navigational intensity plus collision avoidance
Bridge / Engine Watch III
Bridge Watch I This watch has only one Deck Watch Officer on the Bridge during daylight hours providing that all conditions and recommendations stated in OMD Document 004, “Lookouts” are fulfilled. Assistance should be immediately available to the bridge when any of the conditions change. When at sea, a minimum of one crew member (other than the Deck Watch Officer) should be in constant contact with the bridge by radio at all times and to perform lookout duties when required. When in coastal waters, the crew member (other than the Deck Watch Officer) should be on the bridge or close to the bridge. In addition to the above, a watchman is also required during hours of darkness from sunset to sunrise.
Bridge Watch II This watch requires two Deck Watch Officers on the Bridge. Though one officer is usually the Master, under special circumstances the Master may delegate authority to another Deck Watch Officer. By doing so, the Master does not thereby delegate responsibility. If it is anticipated that the vessel will be in this condition for a long period of time it would be normal to double watches with the Master in charge of one watch and the Chief Officer in charge of the other. •

DUTIES OF THE OFFICER OF THE WATCH
The Officer of the Watch is the Master's representative, and his primary responsibility at all times is the safety of the ship. He is responsible for ensuring that the planned passage is properly carried out during his watch. He must at all times comply with the International Regulations for Preventing Collisions at Sea (COLREGS) and the Basic Principles to be Observed in Keeping a Navigational Watch of the International Convention on Standards of Training, Certification and Watch-keeping for Seafarers, STCW Convention. He will also comply with any additional instructions (verbal or written) of the Master. •
CONTROLLED
The Officer of the Watch should keep his watch on the bridge: Under no circumstances should he leave the bridge until properly relieved. A fundamental responsibility of the officer of the watch is to ensure the efficiency of the navigating watch. It is therefore of particular importance that he ensures that an efficient lookout is maintained at all times. On a vessel with a separate chart room, the Officer of the Watch may visit it, when essential, for a short period in order to carry out his navigational duties, but he should first satisfy himself that it is safe to do so and that a good lookout is being kept
Revision: 01 Aug 2013 Approved by DPA/DMR Page 5 of 25
THOME SHIP MANAGEMENT PTE LTD
OMD Document No. 003 Bridge Watch
•
The Officer of the Watch continues to be responsible for the safety and navigation of the vessel despite the presence of the Master on the bridge until the Master informs him specifically that he has assumed that responsibility
•
The Master should establish a recognized procedure for monitoring the actions of the Officer of the Watch in preference to taking over control himself, since in this way he will be able to train the officer by correcting errors and at the same time satisfy himself of the safety of the ship
•
It is the duty of the Officer of the Watch to be aware of any work being carried out near the radar and radio aerials, and of sound signalling apparatus, so that the appropriate warnings can be given. The use of warning notices to hang on equipment controls when such work is in progress is recommended
•
If the duty watch officer is in any way unclear as to his responsibilities or duties, he shall immediately advise the Master
•
Full duties of the various navigating officers are fully listed in HSSEQ System Main Manual
•
Newly joining officers are to report to the Master and, with the officer being relieved, inspect all items for which he is responsible. Only when he is familiar with the operation of all equipment and procedures will he take over responsibility for the watch. The time taken for this will be dependent on the officer’s experience with the equipment and the vessel etc.
Keeping a Good Watch The Officer of the Watch is responsible for the maintenance of a continuous and alert watch. This is one of the most important considerations in the avoidance of collisions, stranding and other casualties. In order to keep an efficient watch the Officer of the Watch should ensure the following: •
an alert all-round visual and aural lookout to allow a full grasp of the current situation, including the presence of ships and landmarks in the vicinity
•
close observation of the movements and bearing of approaching vessels
•
identification of ship and shore lights
•
close monitoring that the course is being steered accurately and that wheel orders are correctly executed
•
observation of the radar and echo sounder displays
•
Observation of changes in the weather, especially the visibility
Changing Over the Watch If a manoeuvre or other action to avoid a hazard is taking place at the moment the Officer of the Watch is to be relieved, hand over should be deferred until the action is completed, i.e. The vessel is on track proceeding towards the desired waypoint at the ordered speed. •
CONTROLLED
The Officer of the Watch should not hand over the watch if he has any reason to believe that the relieving officer is suffering from any disability (including illness, drink, drugs or fatigue) which would preclude him from carrying out his duties effectively. The oncoming officer must comply with the work hours and rest period requirements laid down. If in doubt, the duty officer should consult the Master prior to handing over
Revision: 01 Aug 2013 Approved by DPA/DMR Page 6 of 25
THOME SHIP MANAGEMENT PTE LTD
OMD Document No. 003 Bridge Watch
•
The relieving Officer of the Watch should ensure that members of his watch are fully capable of performing their duties and in particular that they have adjusted to night vision. He should not take over the watch until his vision has fully adjusted to the prevailing light conditions and he has personally satisfied himself concerning the use and condition of Bridge navigating instruments and equipment
•
The officer being relieved shall complete all Log book entries and check operation of all recorders prior to leaving the bridge
•
After handing over the watch, the officer relieved should carry out rounds on board to check for fire, flooding or any other unusual circumstances (e.g. Oil escaping from hydraulic lines)
Periodic Checks of Navigational Equipment The Officer of the Watch should make regular checks to ensure that: •
the helmsman or the automatic pilot is steering the correct course
•
the standard magnetic compass error is established at least once a watch and after any major alteration of course
•
the standard magnetic and gyro compasses are compared frequently and repeaters synchronised
•
the automatic pilot is tested in the manual position at least once a watch
•
The navigation and signal lights and other navigational equipment are functioning properly
Restricted Visibility When restricted visibility is encountered or expected, the first responsibility of the Officer of the Watch is to comply with the International Regulations for Preventing Collisions at Sea (COLREGS) and the Master's Standing Orders, particularly with respect to: •
Informing the Master
•
Posting lookout(s) and calling additional personnel
•
Advising Engine Room of prevailing conditions
•
Exhibiting navigation lights and observing sound signal requirements
•
Operating the radar
•
All these actions should be taken in good time before visibility deteriorates
All actions / precautions taken shall be duly logged in the deck logbook.
Calling the Master The Officer of the Watch should notify the Master immediately under any of the following circumstances: •
If in doubt as to the correct action to take for any reason
•
If visibility deteriorates to the level laid down in the Master's Standing Instructions
•
If the movements of other vessels are causing concern

Despite the requirement to notify the Master immediately in the foregoing circumstances, the Officer of the Watch should not hesitate to take immediate action to ensure the safety of the ship whenever circumstances require. If the Master can not be contacted, either the ships public address system or two short rings on the ships alarm shall be used. Alternately, the Chief Officer or another crew should be called to assist.
Watch-Keeping Personnel The Officer of the Watch should give the watch-keeping personnel all appropriate instructions and information necessary for maintaining a safe watch, including a proper lookout and ensure the Bridge is manned as per the Passage Plan Watch Level requirements.
Main Engines The Officer of the Watch should bear in mind that the engines are at his disposal for assistance in manoeuvring. He should not hesitate to use them in case of need, although timely notice of an alteration of engine movements should be given when possible. He should also be fully aware of the manoeuvring capabilities of his ship, including its stopping distance. The Officer of the Watch should pay particular attention to the following when controlling main engines: •
CONTROLLED
Control of revolutions ahead and astern. The officer of the watch should be familiar with the operation of the engine/propeller mechanism and aware of any limitations. He should appreciate that the type and configuration of the ship's engines will have implications when changing speed or motion. Direct drive diesel, diesel through gearbox or clutch, turbo-electric and gas turbine engines have relatively quick responses to change provided the engines are on "standby". Geared turbines are not as responsive, neither is their change from ahead to astern or vice versa achieved as quickly. The delays and constraints built into engines when operating unmanned will have a substantial bearing on ship manoeuvring. The officer of the watch should therefore be familiar with the actual mechanical procedures initiated by an unforeseen variation in engine speed

Condition and readiness. The Officer of the Watch should know the time taken to achieve both an emergency and a routine stop in both 'open sea' and manoeuvring conditions
Standby Condition The Officer of the watch should ensure that whenever a vessel is navigating in restricted waters as identified under Table 3.1 1: ‘Bridge Watch Conditions’, navigating in adverse weather conditions, in high density traffic areas, port approach or in any other circumstances deemed necessary, the main engine should be in a state of increased readiness or in standby condition as required by the Master. The bridge will normally give the engine room one hour’s notice before manoeuvring speed and additional systems are required. On expiry of this notice period the main engine will be on standby for immediate manoeuvring as required by the bridge. At the time of giving one hour’s notice to the engine room, requirements regarding doubling up of steering gear systems, requirements for additional alternators, requirements for hydraulic machinery and or steam driven machinery must also be considered and similar notice to be given. Appropriate entries are to be made in both the bridge and engine room log books regarding the notice period and standby condition requirements. The OOW should bear in mind that it may not always be possible to give the one hour’s notice as described above and that the main engine is available for use at all times. However, when the vessel is in UMS mode and where circumstances permit, time should be allowed for the Duty Engineer Officer to man the Engine Room before using the engine.
Arrival Port Preparations: The following should be marked on the chart, where it enhances safe navigation: •
Notice to ER – 2 hours or 1 hours notice to be determined taking into account the traffic density, port which the vessel is calling etc.
•
Changes in machinery status; - ME testing to be marked on the chart which should be carried out at least 6 miles before pilot station.
•
Master calling point and position when he has to be on bridge.
•

Helmsman/Automatic Pilot The widespread use of automatic pilots may mean that helmsmen are less experienced than in the past. Provided the equipment is reliable, the autopilot may therefore provide the most accurate means of keeping track in congested waters. •
The Officer of the Watch should bear in mind the need to station the helmsman and change over the steering to manual control in good time to allow any potentially hazardous situation to be dealt with in a safe manner. With a vessel under automatic steering, it is highly dangerous to allow a situation to develop where the officer of the watch is without assistance and has to break the continuity of the lookout in order to take emergency action. The changeover from automatic to manual steering and vice versa should be made in good time by the Officer of the Watch or under his supervision
•
The watch officer must be aware of the possibility that auto-pilot may malfunction and carefully monitor its performance particularly during change over between systems
•
The use of a manual override at the conning position, giving the Officer of the Watch direct access to the steering gear, should be encouraged
•
Instructions for change over between systems and emergency operation of system must be clearly displayed by the steering console. All officers must be familiar with the proper method of change over
•
All Deck Officers and Helmsmen must be thoroughly familiar with the sound and operation of the alarm indicating the helm is being turned while in automatic steering mode. This alarm signals the need to change from the automatic steering mode to manual steering mode in order to initiate steering manually
Helicopter Operations Masters and officers of the watch of vessels likely to be engaged in the transfer of personnel or stores by helicopter should make themselves familiar with the ICS Guide to Helicopter/Ship Operations.
System Controls - Monitoring and Operation The Officer of the Watch is responsible for monitoring other systems and their controls which are located on the bridge. These will include some or all of the following: •
fire detection
•
watertight integrity
•
machinery condition

other specialised requirements
During critical phases, enough manpower must be available to operate all system controls which are fitted on the bridge.
Bridge and Emergency Check Lists The Officer of the Watch should be fully conversant with the procedures in this guide. When time permits, whether the action taken is routine or emergency, the appropriate check list should be consulted in order to ensure that all necessary steps are taken. Vessels fitted with bow thrusters, shaft generators, auxiliary engines, ballast pumps etc. which are controlled from the bridge should have their check lists appropriately supplemented by the procedures to be followed with respect to these controls. Masters should develop Vessel Specific check lists when necessary. The checklist is to be delivered using the samples in the ICS Bridge Procedure Guide.
Compass Error Conditions permitting, compass error shall be determined at least once each watch at sea and at anchor, and for each course steered. This data shall be recorded in the Compass Record Book and Deck Logbook. In restricted or pilotage waters, compass error shall be determined by the use of transit bearings and ranges, and the results similarly logged. •
During the watch, simultaneous checks between the gyro and magnetic compasses shall be made at least hourly
•
Frequent checks shall be made between the master gyro and all repeaters, and other equipment utilising the gyro including the course recorder. Significant discrepancies shall be investigated, corrected if possible, and logged in the Deck Logbook
•
A current deviation table shall be maintained and available to the Deck Watch Officer
Determining the Vessel’s Position All of the vessel’s navigational equipment must be used, as necessary, to determine the vessel's position. The advantages and limitations of each aid must be fully understood. •
To obtain confirmed fixes, each fix shall be compared to another fix obtained by an alternate means (GPS is not to be used as a sole means of navigation). All terrestrial fixes shall consist of three position lines - a single bearing and range is open to error. All fixes must be plotted on the navigation chart in use
•
A buoy or any such market liable to shift, and a fixed point shall not be used as a range unless no alternative exists

•
Radar bearings taken to points of land must be selected carefully. Isolated rocks, beacons, etc., which are clearly defined and shown on navigation charts and not subject to shifting with winds and currents are preferable
•
Positive identification of navigation lights (lighthouses, buoys, beacons, etc.) shall be made
•
Deck Logbook entries shall be made of time, distance off, and vessel speed when abeam of navigational lights, aids, and prominent points as applicable
•
Fixes shall remain on charts until the passage is completed
•
Soundings are to be taken using the echo sounder when making a landfall, when the vessel is in unfamiliar, restricted, or shoal waters, or at any other time when soundings may assist in establishing the vessel's position
•
Whenever dangers to navigation exist in restricted waters or in coastal areas, the Master and Deck Watch Officers must ensure that frequent checks of the vessel's position are made by alternative methods to eliminate the risk of grounding or stranding because of human or mechanical error
Navigation in Coastal Waters The charts used should be the most suitable for the planned passage. The Officer of the Watch should positively identify all relevant navigation marks. Position fixes should be taken at regular intervals, the frequency depending upon factors such as distance from nearest hazard, speed of ship, set experienced etc. •
Radar is generally used in coastal waters to supplement visual fixing. When navigational marks are not clearly visible, or in restricted waters where continuous monitoring of the ship's position is desirable, radar should be used for parallel indexing and can replace visual fixing altogether
Ship at Anchor A continuous anchor watch is to be maintained. The officer of the watch should: •
ensure that the vessel exhibits the appropriate lights and shapes and that in restricted visibility the appropriate sound signals are made
•
ensure that an efficient lookout is maintained
•
ensure that the state of readiness of the main engines and other machinery is in accordance with the Master's instructions
•
determine and plot the ship's position on the appropriate chart as soon as practicable, and at sufficiently frequent intervals check this position by taking bearings of fixed navigational marks and, or marks monitored by automatic radar plotting aids or readily identifiable shore objects
•
observe weather, tidal and sea conditions
•
notify the Master if the vessel drags its anchor and undertake all necessary remedial measures
•
notify the Master if visibility deteriorates
•
ensure than an inspection of the vessel is made periodically
•
Under appropriate circumstances maintain anti-piracy precautions as laid down in the Master's Standing Orders

Delegating Authority Although Masters remain responsible for their vessels at all times, conditions may arise under which Masters must rest or attend to other responsibilities. Masters, therefore, must pre-plan their presence on the bridge and consider delegating their authority to the Chief Officer or a Deck Watch Officer in order to allow themselves adequate rest. Deck Watch Officers must know where they can contact the Master at all times. Failing this, two short rings of the General Alarm or a PA announcement shall be the preferred method for contacting the Master in an emergency. In the event that the Master can not be located the Chief Officer must be contacted.

As all Officers and Lookouts who stand a watch on the bridge know, there are times when it can be very easy to lose concentration. This is more prevalent around about 0300 to 0500 hours when the body’s bio rhythms are at their lowest. During a review of incidents within the industry, it was found that a high percentage of incidents occurred between a time frame of 0200 – 0500 hours. In view of this review, a change in the watch keeping hours on the bridge is required. The advantages of the change are as follows: •
Every two hours there is a fresh member of the bridge team revitalising the watch system
•
Fire watches can be performed during the night at intervals of 2 hours without contravening STCW 95, enhancing fire prevention and safety
•
Evening meal relief for lookouts are no longer required

The distance between sea buoy and speeding up to full speed or slowing down to harbour manoeuvring speed is considered harbour approach and is not for use in the calculation of sea speed performance.
Manoeuvring Characteristics of the Vessel All Deck Officers must have a working knowledge of what can be expected from their vessel’s performance. This includes engine manoeuvrability and limitations, turning information, stopping times, and distances. All Deck Officers shall be completely familiar with the "Manoeuvring Characteristics" placard on the Bridge. It must also be understood that the manoeuvring characteristics are for loaded and ballast drafts. Variables such as depth of water, under-keel clearance, draft, trim, and environmental conditions can greatly affect the handling characteristics of the vessel. Deck Officers should endeavour to familiarise themselves with the handling characteristics of the vessel for all conditions of operation.
4.2
PILOTAGE
The Master must employ a Pilot or Mooring Master whenever the safe navigation of the vessel or regulations makes it necessary, unless other arrangements have been made with the company. With regard to Masters piloting their own vessels, Thome will evaluate each case on an individual basis, and not have a standardised policy applicable to all ports and all Masters. No Master will pilot a Thome vessel without prior authorisation, except in cases of emergency.
Pilot Embarkation and Disembarkation When the vessel’s pilot station ETA has been established, the Deck Watch Officer or Master will contact the pilot station to arrange for the Pilot’s boarding. The Deck Watch Officer will communicate with the pilot boat as soon as possible via VHF to confirm ETA and to establish on which side of the vessel the Pilot will board, and the vessel's heading and speed at the time of boarding.
Pilot Ladders Pilot ladders are: •
To be maintained in clean good working order and be constructed of a single length of rope with spreaders and non-slip steps made of hardwood or equivalent except the bottom four steps, which may be constructed of rubber
•
To be rigged properly:

A heaving line A lee is to be provided from the weather The requirements for SOLAS Pilot Transfer Arrangements have been amended in 2010, and have come into force on 01 July 2012. They will affect the fitting of new installations on new and existing ships, and may impact existing arrangement on existing ships. These regulations, contained in IMO Resolution MSC.308 (88), are summarized below: New Pilot Transfer Arrangements Pilot transfer arrangements installed on or after 1 July 2012 are to comply with the latest amendments to SOLAS regulation V/23, which revise some of the previous requirements. Some of the notable revisions are: • Pilot ladders are to be certified by the manufacturer as complying with SOLAS or with an acceptable international standard (e.g., ISO 799:2004, "Ships and marine technology - Pilot ladders"). • Pilot ladders used for pilot transfer are to be clearly identified with tags or other permanent markings to enable identification of each appliance for the purposes of survey, inspection and record keeping. A record is to be kept as to the date the ladder is placed into service and when is undergoes any repairs. • A mechanical pilot hoist is no longer a valid pilot transfer arrangement. • IMO Assembly Resolution A.889(21) has been superseded by A.1045(27). A significant change between these resolutions was adopted for pilot transfer arrangements using accommodation ladders in conjunction with pilot ladders. While A.889(21) allowed a maximum inclination angle of 55°, resolution, A. 1045(27) now requires that, "The length of the accommodation ladder should be sufficient to ensure that its angle of slope does not exceed 45°. In ships with large draft ranges, several pilot ladder hanging positions may be provided, resulting in lesser angles of slope. The accommodation ladder should be at least 600 mm in width." • A.1045(27) also contains requirements for pilot ladder winch reels, when these are provided, with regard to its arrangement/positioning, securing, etc. At this time the following guidance is provided for determining when a pilot transfer arrangement is considered to be "installed on or after 1 July 2012": 1) For ships with a building contract placed on or after 1 July 2012, or in the absence of the contract, constructed on or after 1 July 2012, "installed on or after 1 July 2012" means any installation on the ship. 2) For ships other than those ships prescribed in 1) above, "installed on or after 1 July 2012" means a contractual delivery date for the system to the ship on or after 1 July 2012 or, in the absence of a contractual delivery date, the actual delivery of the system to the ship on or after 1 July 2012. (This does not apply to equipment and arrangements installed on or after 1 July 2012, which are a replacement of existing equipment and arrangements that were installed onboard before 1 July 2012.) As the guidance in item 2 above will be the subject of further discussion at IMO during MSC 90 in May, acceptance by the vessel's flag state would be needed prior to the application of this guidance in specific cases at this time. Existing Pilot Transfer Arrangements Arrangements on ships constructed before 1 January 1994 are required to comply, no later than the first survey on or after 1 July 2012, with regulation V/23.5.

Marking of gangways and Accommodation Ladders Each accommodation ladder or gangway should be clearly marked at each end with a plate showing the restrictions on the safe operation and loading, including the maximum and minimum permitted design angles of inclination, design load, maximum load on bottom end plate, etc. Where the maximum operational load is less than the design load, it should also be shown on the marking plate.
Master-Pilot Data Exchange When employing the services of a Pilot, Masters will use the Master/Pilot check list and Pilot card to facilitate the exchange of information between the Master and Pilot. After reviewing local navigational and weather conditions, the Master will discuss the vessels manoeuvring characteristics and light or loaded condition with the Pilot or Mooring Master promptly upon boarding, acquainting them with any unusual characteristics or malfunctioning equipment. Manoeuvring Characteristic diagrams will be conspicuously posted in the wheelhouse for easy viewing by all ship handlers. At a safe and convenient time after the Pilot or Mooring Master boards the vessel the Master will complete the Master/Pilot Check List form. The Master should question the Pilot, using the checklist on the front of the card listing important questions regarding the Pilot’s intended transit plans, including an understanding of the courses and speeds at which the vessel will proceed. The Master’s objective should be to ensure that the plan is safe, and that the expertise of the Pilot or Mooring Master is fully supported by the Bridge team. The back of the card should provide a plan outline of the vessel for illustration of anticipated tug tie-up and mooring line arrangements by the Master or the Pilot or both. This activity must not distract from the Pilot’s duties.
Master, Deck Watch Officer and Pilot Relationship The Master is the ultimate authority on the vessel and is responsible for its safe navigation. Pilots and Mooring Masters are important advisers to navigation, but the Master remains responsible for their actions, whether they are acting alone or with the Master. The Master will ensure that Deck Watch Officers are capable of acting on the Master's behalf with a Pilot or Mooring Master should the Master need to leave the Bridge. Diplomacy and tact must govern commands made to the Pilot or Mooring Master to obtain the safest ship handling performance. Whilst the Pilot is on board, all due courtesies are to be extended to him. However, the Pilot should be left with no doubt that he is on board on an advisory basis and the Master (and the bridge team) needs to be satisfied of the Pilots intended actions for the safe transit of the vessel to/from berth, or as the case may be. Masters should not hesitate to question the Pilot in case of any doubts and retorts such as “Don’t worry”, “I have been pilot for x number of years”, “I am Senior Pilot” etc., should not deter the Master in any way. A diplomatic and amicable discussion is of course the preferred solution. However, if these approaches do not work, then the Master needs to be as firm as may be required under the circumstances to establish his authority and command of his vessel. More importantly, the rest of the Bridge Team need to be totally aware and in compliance with the Masters disposition and mind frame in these circumstances and should have no hesitation in whose orders to follow. Masters are reminded once again that the safety of their vessel’s remains their responsibility at all times and they need to take whatever action as may be required to ensure the same.
Pilot’s or Mooring Master’s Compliance with Rules Masters and Deck Watch Officers must insist when proceeding in all waters that the Pilot or Mooring Master complies with COLREGS and observe speed restrictions when navigating rivers and narrow

channels, with due regard for the conditions likely to be encountered en route to the vessel’s destination.
Judging the Pilot’s or Mooring Master’s Ability Masters and Deck Watch Officers must remain alert to the Pilot's or Mooring Master's handling of the vessel and be prepared to intervene when necessary to safeguard personnel, environment, vessel, and cargo. Masters and Deck Watch Officers must observe the helm and engine orders advised by the Pilot or Mooring Master and promptly determine whether the Pilot's or Mooring Master's orders will produce the desired results, based upon their understanding of the vessel's handling characteristics. In the event that the Pilot or Mooring Master fails to act on the Master's or Deck Watch Officer's direction when the Master or Deck Watch Officer judges the safety of the vessel to be in jeopardy, the Master or Deck Watch Officer must countermand the Pilot's or Mooring Master's instructions. He must act so as ensure the safety of the vessel. Full details of any such actions must be entered in the Deck Logbook.
Navigation with Pilot Embarked The presence of a pilot does not relieve the Master or the Officer of the Watch of their duties and obligations. The Master should inform the pilot of the ship's characteristics using a pilot card. An example of a pilot card recommended internationally is reproduced in ICS Bridge Procedures Guide. This card should be completed as directed by the Master and handed to the pilot on boarding. The Master should request information from the pilot regarding local conditions and his navigational intentions. This information should be in a form to enable the Master or Officer of the watch to monitor the planned passage. The Officer of the Watch should cooperate closely with the pilot to assist him where possible and to maintain an accurate check on the ship's position and movements. If the pilot requires the use of a radar or other bridge equipment, then the use and limitations of the same should be discussed with the pilot and the proper operation of the equipment should be monitored by the Officer of the Watch. If the Officer of the Watch becomes unsure of the pilot's actions or intentions, he should seek clarification and, if still in doubt, should inform the Master immediately and take the necessary action before the Master arrives on the bridge. If the Master is of the opinion that the Pilot is manoeuvring in an unsafe fashion or at speeds which are too high, he should immediately express his concern to the pilot. In the event that the Pilot does not accept the Masters advice, then the Master should take appropriate action. Master’s are reminded that except in the case of the Panama Canal, the Master remains in command of the vessel. In the case of the Panama Canal, it is suggested that a log entry be made and the Canal Authority be advised of the Pilots actions. In the event of an accident occurring whilst the pilot is on board, a certificate exonerating the pilot from responsibility for such mishap shall under no circumstances be given. When a ship is under pilotage the Master shall not be absolved from his responsibility for the safe navigation, even when the pilotage is compulsory. He shall intervene, or take over from the pilot, whenever necessary in order to avoid a close quarters or dangerous situation. The Chief Engineer is to make his requirements for the general running of the Engineering Department and watch-keeping, emergency, and other individual duties known to the engineers by means of Standing Orders. These orders should be typed, posted in the engine room, and must be signed by each Engineer serving concurrently with the Chief Engineer. Please refer to HSSEQ Circular 16 – 2009 for further guidance.

Evidence of documents submission A documentary evidence (singed or email copy of early requirements)of similar sets of documents being submitted either to the agent or direct to the customs authority should be retained on board to prevent allegations of mis-declaration or other form of subtle fault finding to the vessel.
6.7 REPORTING OF BREAKDOWNS, ACCIDENTS EQUIPMENT IN AUSTRALIAN WATERS
AND
DEFECTIVE
The Australian Maritime Safety Agency (AMSA) have found that there is an increasing number of vessels that are failing to report defects to ships equipment as required by the Navigation Act and SOLAS. There are requirements under both the Commonwealth Navigation Act [Section 268] and SOLAS [chapter 1, Reg11(c)] for ships to report incidents, accidents, breakdowns and defective equipment.
CONTROLLED
Revision: 06 Dec 2013 Approved by DPA/DMR Page 6 of 19

SOLAS Chapter 1, Regulation 11(c) - Whenever an accident occurs to a ship or a defect is discovered, either of which affects the safety of the ship or the efficiency or the completeness of its life-saving appliances, or other equipment, the Master or owner of the ship shall report at the earliest opportunity to the Administration [Flag state], the nominated surveyor or recognized organization [classification society] responsible for issuing the relevant certificate, who shall cause investigations to be initiated to determine whether a survey is necessary. If the ship is in the port of another Contracting Government [port state i.e. Australia], the Master or owner shall also report immediately to the appropriate authorities [AMSA] and the nominated surveyor or recognized organization shall ascertain that that such a report has been made.
Method of Reporting The correct method of reporting to AMSA is by use of the AMSA Form 18 Incident Alert [to be completed within 4 hours] and AMSA Form 19 Incident Report [to be completed within 72 hours]. These forms are available from the AMSA web site www.amsa.gov.au and should be sent in the first instance to
[email protected] Additional methods of reporting for ships when in the AUSREP AREA is to follow the information in Section 7.2 of the AUSREP Book and report via the RCC. It should be noted that penal provisions do apply for failure to report under the Navigation Act. Vessels failing to report under the SOLAS requirements may find themselves undergoing additional scrutiny and or deficiencies being issued in a PSC inspection. As a reminder to all Masters of Thome Fleet, the DPA along with the Marine / technical Superintendents should also be notified if any vessel has a defect which effects its statutory certification. Whether, that is equipment which affects the safety of the vessel or the marine environment, wherever that vessel may be.
Incident Reporting Incident reporting in Australia is covered by two separate mechanisms that must be followed by the shipping industry. The mechanism to be employed is determined by the nature of the information to be reported. The two mechanisms are: General Incident Reporting: covering accidents, damage to ships, injuries to crew and births, deaths and marriages. Pollution Reporting (MARPOL): covering discharges, or probable discharges of oil, chemicals, or harmful substances in excess of permitted limits, or damage, failure or breakdown of a ship of 15 metres or more in length. It should be recognised that the two mechanisms are not mutually exclusive and some incidents will require reporting under both mechanisms. An example of such a situation would be a collision that also results in the release of oil and/or dangerous cargo into the environment. Report of Suspected Non-compliance with Navigation Act or Safety/Pollution Conventions (SV-HH): In addition to the two formal reporting mechanisms noted above interested third parties may report suspected deficiencies to AMSA by completing the attached form (Report of Suspected Non-compliance.docx)
General Incident Reporting The requirements for general incident reporting as they relate to individual legislative requirements are described in detail below
Format of General Incident reporting Incident reports are made using form ‘AMSA 18’ and form ‘AMSA 19’.

Form ‘AMSA 18’ is an incident alert designed to inform the authorities that an incident has occurred, however, this will not include all the information that will eventually be required. This report must be submitted by the master within 4 hours of the incident occurring and may be sent by: Fax to: +61 2 6230 6868 or 1800 622 153 (free fax within Australia), or Email to:
[email protected] If additional information is required in respect of the submission of this form the Rescue Coordination Centre (RCC) can be contacted on 1800 641 792 and they will provide advice. To provide the details of the incident a “detailed report” (form AMSA 19) is to be forwarded to AMSA, Canberra within 72 hours of submission of the incident alert (form AMSA 18). The details for faxing or emailing incidents reports (Form AMSA 19) are: Fax to: +61 2 6279 5058 Email to:

When Is Incident Reporting Required? The requirements for reporting are detailed below. It should be noted that Australian legislation provides significant penalties for failing to comply with any report requirements. The information provided below is a summary of the principal requirements of the relevant legislation; however, is it recommended the legislation itself be consulted when more information is needed? This legislation is available on the AMSA website.
Reporting Under MARPOL The requirements for reporting pollution or potential pollution incidents as contained in MARPOL and associated documents are described in detail below. Details of who to report such incidents to are provided in Shipboard Oil Pollution Emergency Plans. Relevant contact points in Australia are provided in the AMSA notice on reporting MARPOL incidents which should be retained with the Shipboard Oil Pollution Emergency Plan when in Australian waters A listing of global contact points or points responsible for the receipt, transmission and processing of urgent reports on pollution incidents from ships to coastal states is maintained by IMO as an MEPC.6 (sent to the fleet ever Quarter) CONTROLLED

For ships in a port at the time of an incident, or probable/potential incident, notification should also be made to the local authorities in addition to AMSA/RCC as described in the links above. This will ensure compliance with Australian Commonwealth/State/Territory legislation obligations and that the relevant local contingency plan is activated in a timely manner, if necessary. Purpose of Reporting The purpose of the MARPOL reporting obligations is to enable the Australian Maritime Safety Authority and other responsible agencies to be informed quickly and accurately about actual or potential accidental spillages or cargo losses. This will enable any necessary response actions or assistance to be initiated promptly. Format of MARPOL Incident reporting These reports are to be submitted in the standard format adopted by IMO for this purpose in IMO Resolution A.851(20) as amended by Resolution MEPC.138(53). It should be noted that the reporting format for Oil or Noxious Liquid Substances (NLS) is different to that for packaged dangerous goods, however this is detailed in A.851(20) (Please refer to Vessel’s SOPEP / SMPEP Manual(Section 2) for the reporting procedures. When is MARPOL Incident reporting required? Article 8 and Protocol I of MARPOL contain comprehensive requirements for a report in the required format to be made to the nearest coastal , without delay, when an incident involves: a.

Reporting to Administration for Marshall Island vessels The Marshall Islands Administration established a 96-hour pre-arrival reporting requirement to the flag State for vessels bound for U.S. ports in November 2002 per Marine Safety Advisory 27-02. A recent detention of a Marshall Islands ship in the United States, that failed to report its arrival to the Administration, brings to their attention the need to provide yet another Marine Safety Advisory stating notice of arrival requirement. Masters and/or vessel agents must notify the flag State of a vessel destined to a U.S. port concurrently with U. S. Coast Guard National Vessel Movement Centre (NVMC) notice (96 hour NOA). NVMC provides an electronic version of the Notice of Arrival called e-NOA which is available on their website: http://www.nvmc.uscg.gov/Forms/NOAForm.xls. The preferred method of notification of the Administration is by e-mail to the address:

It rests with the Master to ensure that all long-distance calls from the ship are recorded in a telephone log and charged to the person who makes them.
•
The telephone log should record, caller, number called, the time involved, and the cost of the call.
•
If the telephone is attended by a watchman from shore, he may be charged with the task of keeping the telephone log. To facilitate control, the watchman should be given a copy of the crew list.
Information to Crew •
Information concerning customs regulations, smoking, traffic in the dock zone, landing cards etc. should be given to the crew members as early as possible.
Board Showing Time of Departure •
A board showing the ship's estimated time of departure and end of Shore Leave is to be displayed at the gangway, or on the ship’s notice board.
Repairs to Machinery •
The Chief Engineer must not commence any work that will make engines or vital auxiliaries inoperative without obtaining the Master's consent and local authority's approval.
Supplying Information to Outsiders •
During inward or outward clearance, the Masters of our ships will be required to give some routine information to the port authorities and others entitled to such information. However, the information given should be confined to essentials.
•
In connection with accidents or oil pollution etc., media representatives often seek interviews with the ship's officers and crew. The comments made at such interviews may have a harmful effect on subsequent proceedings. Therefore, it is impressed upon Masters that, until special permission has been obtained from Thome, no information other than what is strictly necessary should be given to the public.
Information Concerning Next Port of Call •
Before leaving port, the Master must ascertain that the ship possesses adequate approach and harbour charts for the next port. All necessary information concerning the next port of call should be procured before departure.
•
If re-directed whilst at sea, the Master is to immediately ascertain whether adequate information is available concerning the new port of call. If in doubt on any point, he should contact the agent, Thome or the instructing party.

BILLS OF LADING Purpose To clearly define the procedure for checking and signing Bills of Lading
Application All Vessels
Responsibility Master
8.1
GENERAL
The legal document in connection with a charter transaction is the Charter Party. Therefore, the Bill of Lading is, normally, a simple form which refers to the terms and conditions of the Charter Party. It is an extremely important document which serves three purposes: •
a receipt for the cargo, by the vessel
•
a document of title through which ownership of the cargo may pass from one party to another
•
a contract governing the carriage and delivery of the cargo
A Bill of Lading should be checked with the utmost care before it is signed. The Captain signs the Bill of Lading on behalf of Owners and not on behalf of Charterers or Shippers. Third parties (charterers or shippers) have limited powers to interfere with the Captain signing it. In particular, the Captain has no authority to sign for goods which he knows have not been shipped, nor has he authority to vary the terms of the Charter Party governing the vessel's employment, and no third party can require him to do so. Six points should be checked before the Bill of Lading is signed: •
Description of cargo
•
Date of Bill of Lading
•
Terms and conditions
•
Ports of loading/discharging (often unknown)
•
Payments of freight
•
Quantity
Description of Cargo The description of the cargo must be consistent with the cargo details contained in the fixture. No false statements are allowed in the Bill of Lading, e.g. description blended in the ship's tanks.
Date of Bill of Lading The Bill of Lading must be dated correctly, as an incorrectly dated Bill of Lading is a fraudulent Bill of Lading.
CONTROLLED
Revision: 01 Apr 2012 Approved by DPA/DMR Page 1 of 5

Please note: disconnected.
OMD Document No. 008 Bills of Lading
The correct date is the date on which loading was completed - hoses were
In case of need, the day before is acceptable, provided the vessel was physically loading that day.
Terms and Conditions It is important that the Captain incorporate the terms of the Charter Party in the Bill of Lading. The Bill of Lading should contain the following words: “This shipment is carried under and pursuant to the terms of the Charter Party dated ..... at..... between..... and..... as charterer and that all terms whatsoever of the said Charter are to apply to and govern the right of the parties concerned in this shipment" The blanks should be filled in with the date and place and the names of the owner and the charterer.
Ports of Loading/Discharge Port or Ports of loading is to be stated correctly. The destination may be stated as a named port or as a range of ports, however, the description of the destination must be consistent with the Charter Party terms.
Payment of Freight Freight is usually payable at the destination, and statements such as "FREIGHT PAID" or "FREIGHT PREPAID" should under no circumstances be allowed in the Bill of Lading unless specific instruction or approval has been given by Thome, even if vessel is on time charter or sub-let on Time Charter to a third party. Ensure the Bill of Lading contains the clause "Freight payable as per governing Charter Party.” For use when agents are not in possession of the acceptable Bill of Lading forms and for issuance of a fresh set of Bill of Lading as mentioned earlier, the vessel should maintain a supply of blank "INTERTANKBILL 78" or "CONGENBILL" Bill of Lading forms.
Quantity Sellers or shippers do not load more than they have to. At the discharge end the receivers or consignees want what they have paid for, it is, therefore, essential that the Captain does not sign for more than what has actually been loaded on board the vessel. In order to have a uniform system for signing or accepting the differences between ship and shore figures the following sequence and explanation should be consulted, by Captains, and used as a guideline when deciding to accept the figures or not. Some product carriers have an "experience factor", showing the vessel to be either over, or under calibrated, and the Captain should include this in his ship's figure calculation, while following the sequence. When shore and ship's figures are identical for up to a difference of +/- 0.1%, the Master can sign the Bill of Lading as clean and no Letter of Protest need be issued. In all other cases, the guidelines in the sketch should be followed. Please note : In some ports, particularly in Rumania and the USSR, the Bill of Lading weight can be calculated on the basis of specific gravity "in vacuum" as against the normal "in air". If this is the case, it must be clearly stated in the Bill of Lading

Procedure for signing Bill of Lading All ship figures must have Vessel Experience Factor (if any) applied before entering this table. If possible have shippers and independent surveyors attend any ship re-gauging. In the cases of extremely small parcels or small parcels in large tanks then issue protest making reference to this, protest difference and sign Bill of Lading (refer to P&I club if in doubt). If shippers or charterers become unreasonable due to failure to sign Bill of Lading (or refuse to reissue or correct Bill of Lading) because the Master is following the procedures in this table then advise that Masters instructions are to clause or to endorse the Bill of Lading with ships figures: “Vessel’s measurements are stated below, and this Bill of Lading is issued without prejudice to the Owner's rights to rely on said measurements as evidence of the weight or quantity shipped. Vessel's measurements on completion of loading are noted as ………….”. Where the vessel is issuing Bill of Lading (discharging to another vessel / lightering, etc) then the Master is to receive clear instruction from the charterers for the format of the Bill of Lading and these instructions are to be made known to Thome and the vessels owners. In all cases of doubt, arising from Bill of Lading presented then refers to the P&I club for instruction.
8.3
BLANK BILLS OF LADING
The signing of blank Bills of Lading is not acceptable and if a blank Bill of Lading is presented by the Shippers then the Master is to refuse to sign. If this practice is encountered then it is to be brought to the immediate attention of Thome, Owners and Charterers. The Master is authorised to sign a blank Bill of Lading after receiving written instructions from the vessels Owners and advising Thome accordingly. Masters are not to sign any blank Bills of Lading on the instruction from any other party (charterer, agents, shippers, surveyors, etc).

OMD Document No. 008 Bills of Lading
BILLS OF LADING OR DISCHARGE OF CARGO
Bills of Lading are the “owners” document and the cargo should only be delivered against, or in return for, the surrender of an original Bill of Lading, when the Bill of Lading is said to be “accomplished”. •
As a matter of good practice, the Master should always seek confirmation from the agent that the delivery of cargo will be made against an original Bill of Lading.
•
If this is not the case, the Master should immediately contact the owners for instructions.
•
Under no circumstance should the Master commence discharging unless original Bill of Lading is surrendered or the fact that an owner has accepted an LOI is confirmed.

9.1
CHARTER PARTIES - GENERAL
Thome has provided the vessel with a file containing copies of the most commonly used Charter Parties. Should you come across a C/P form reference which is not available onboard please inform Thome. Each Charter Party has a commercial Code name, which will be stated in our cable/telex with fixture details for your ready reference. Thome fixture details message will also contain the essence of special conditions and clauses negotiated for the particular voyage, which are of interest to the vessel, such as notice clauses, pumping rates etc.
9.2
TIME CHARTER
Under a time charter the vessel is put at charterer's disposal for a certain period of time, usually against a monthly payment expressed as a rate per ton summer deadweight, or on a daily hire basis. The Time Charter Party contains the terms and conditions agreed upon between owner/charterer, e.g. time and place of delivery and redelivery, trading limits, cargo allowed and the hire. Under a Time Charter the vessel is under the direction of the time charterers, and they are under obligation to give you all instructions in writing. The time charterers pay for bunkers, port charges, pilotage, canal dues etc. While the owner pays only the expenses pertaining to his own business, e.g. maintenance of the vessel and expenses incurred in connection with master, officers and crew. Overtime and communication expenses are, usually, a fixed amount monthly, in addition to charter hire.
Responsibility •
Masters will receive all voyage and loading instructions from the charterer. These instructions must be adhered to. Basically the duties of the vessel will be the same as under a Voyage Charter, except that the voyages are performed on behalf of the Time Charterer.
•
Masters are to copy Thome the initial voyage instructions received from the charterer. If charterer's instructions are not in accordance with the Charter

Party terms you must immediately inform us so that we can discuss/clarify the instructions with the charterers.
Bunkers •
All fuel and diesel onboard at the time of delivery on Time Charter will be bought by the charterer, who will also be in charge of further bunkering.
•
When the vessel is redelivered, the charterers will sell all fuel and diesel onboard back. It is normal practice to engage a surveyor to establish the exact quantities of bunkers at time of delivery and redelivery. Nevertheless, the charterer shall be able to get exact information about bunkers onboard at any time during the charter period. o
9.3
It is still the vessel's responsibility, always to ensure that there are sufficient bunkers onboard, including established safety margins, for the voyage in question.
DEADFREIGHT
In the event that quantity supplied by shippers is less than what charterer's voyage orders call for, the Captain is to contact charterers immediately to advise them of the situation and obtain their orders in writing whether to await further cargo from shippers or complete loading with whatever quantity made available to vessel by shippers and then on behalf of charterers lodge protest to shippers regarding the quantity short loaded compared to quantity called for in the voyage order and in all respect adhere strictly to charterers revised load orders or requests for protest to be issued by Captain, If any. •
If the quantity of cargo requested by the vessel in accordance with the Charter Party is not supplied, the vessel has the right to claim deadfreight for the difference.
•
When the Bill of Lading is presented, the Captain should present a protest with the following wording (see Form TSM 25) :
•
"According to the Charter Party dated........... the vessel is fixed for (quote our fixture/telegram,) however on completion of the loading a short loading of ........ M/T has been ascertained.
•
I hereby formally protest and reserve on behalf of owners all rights, which they have in terms of the governing Charter Party to ensure the timely payment of deadfreight on the quantity short loaded."
•
A representative from the installation should sign the protest and the Calculation of Deadfreight. (Forms TSM 24 & 25)
•
The Captain should include the deadfreight tonnage claimed in the departure telex/telegram and copies of the protest and the calculation should be mailed to TSM.
•
Should the representative refuse to sign or receive the receipt of the protest, the protest should be telexed or cabled to the shipper or charterer before departure of the vessel to give this party the opportunity to supply the required additional cargo.
•
An entry should be made in the logbook saying that the representative refused to sign.

•
An independent surveyor can be called in to verify your calculation by his separate statement/report in the event charterers' representative refuses to sign your calculation.
•
When a Captain is notified that the vessel is sub-chartered to a third party, he is to make sure that all instructions received from the new charterers are in accordance with the governing Charter Party and that the instructions do not go beyond the original Charter Party between Thome and the original charterers. o
9.4
OMD Document No. 009 Charter Parties
The Captain must copy Thome the initial voyage orders and any changes thereto.
SUB CHARTER / SUB-LETTING
It might happen on Time Charter and very seldom on a Voyage Charter that the charterers "sublet" the vessel to a 3rd party. In such a case, the Captain is acting both as owners' and as the charterers' (T/C Owners') representative, and he is to take care of all matters on their behalf, bearing in mind always to protect Thome interests.
9.5
VOYAGE CHARTER
Under a voyage charter the vessel is put at charterer's disposal for the carriage of a full or part cargo from one or more ports to either named port(s) of destination or port(s) within a certain range at rate(s) and conditions agreed to in C/P.
9.6
•
The charterers are granted a certain amount of time (laytime) within which to load and discharge the vessel, usually 72 hours SHINC (Sundays, Holidays included).
•
For time spent in excess of agreed laytime, charterers are charged demurrage, (no dispatch in tanker trade).
FREIGHT EARNINGS
Vessels are, usually, fixed according to "World Scale" or, as an alternative, on a lump sum basis. •
If fixed on basis World Scale, freight is earned on the basis of cargo intake or minimum quantity guaranteed by charterers. Flat rate is obtained from World Scale as per ruling tariff, i.e. any combination of loadports/discharge ports worldwide have a special "flat rate" per ton cargo scale points owners/charterers have negotiated/agreed upon. As an addendum to this paragraph please find the introductory pages to the current world scale.
•
When fixed on world scale terms and conditions it is imperative, subject to charterers voyage orders, that vessel loads maximum cargo available but always subject to quantity stated in Charterers voyage orders, Owners normally obtain freight in excess of cargo fixed, for instance if fixed 27,000 mt. Any cargo lifted in excess of this quantity will be paid for by charterers usually at half the basic freight rate (called 50% overage). Consequently, it is important that when charterers voyage orders are received, the Captain calculates max. cargo intake with due consideration to the restrictions prevailing in loadport/discharge port, which weather zones vessel will transit enroute, as well as bunker consumption enroute to the discharge port and possible bunker stem loadport/or

enroute, if there is no draft restriction at the loadport, but only restriction being at the discharge port. •
Above max cargo intake to be conveyed to Thome who will inform charterers in an endeavour to persuade them to accept maximum lifting over and above quantity actually fixed.
•
If the vessel is fixed on lump sum - owners/vessel are only obliged to lift the cargo as per fixture details and as such we do not have the same incentive to increase the cargo intake as described above, as we do not obtain additional freight for excess cargo over and above what actually fixed. o
Ship owners have to pay all operating expenses out of the freight, e.g. port charges, cost of bunkers, agency fees etc.
o
Possible loss of time enroute due to weather is also for owner's account.
o
Thome will issue or relay to vessel voyage orders/ instructions to be adhered to.
Bunkers - Voyage Charter In order to achieve the most economical operation and optimal purchase of bunkers, Thome will contact vessel giving the intended bunkering programme for vessel's consideration and evaluation, taking into account vessel's safety margin for the given voyage. We remind Captains that it is their responsibility that vessel's safety requirements are always maintained and vessel is able to perform the voyage in question. After receipt of vessel's comments/agreement to the bunkering programme, stem will be placed via Thome, who in turn will give full details of stem to suppliers/agents and vessel.
9.7
NOTICE OF READINESS
It is the Captain's responsibility to notify the charterer or his agent, in writing, as soon as the vessel has arrived at the Port and is in all respect ready to load or discharge. This advice is given in the form of a "NOTICE OF READINESS" (NOR) by using TSM Form 012. NOR is also to be tendered to the parties stipulated in the Charter Party, and or the Voyage Orders, by either cable or direct telex upon arrival in port. The cable or telexed, NOR, must be followed up by the printed NOR form which to be signed by charterers' representative upon berthing. Before the NOR may be tendered, the following conditions must be met: •
•
The vessel must have arrived at the place for loading or discharging as stipulated in the Charter Party and or voyage orders or as near to as the vessel can get with safety. o
NOR is to be tendered when arriving at the customary anchorage or arriving at the pilot station whichever comes first.
o
Time and location when giving NOR is to be entered in vessel's log book.
The vessel must be actually ready to load or discharge cargo at the specified time. However it is the custom of the trade that the NOR is valid when tendered even though the vessel is arriving with ballast on board. o
CONTROLLED
If the vessel arrives before laydays commence, NOR should be tendered anyway in order to give the charterer the opportunity to accept the vessel earlier and to use the customary 6 hours' notice time, unless otherwise instructed by Charterer.

o
The rules for calculation of laytime vary considerably, the Captain should carefully read the clauses concerning notices, laytime and demurrage in each Charter Party to ensure "Notice of Readiness" is tendered at the right time, to be safe, ensure notice is tendered immediately upon arrival load or discharge port.
o
Please ensure that the governing dates and hours are clearly stated in the "Statement of Facts". (TSM Form 017)
NOR per Charter •
It is extremely important that all instructions and notices as per Charter Party and charterers' voyage orders are strictly adhered to. As the Notice of Readiness (NOR) establishes the start of laytime the procedure of establishing same requires correct communication procedure.
•
NOR by telex: Charterers designated NOR receivers should be telexed direct and the vessel must receive the correct answer back from the recipient.
•
If the above procedure is impossible NOR must be sent as a cable to the designated receivers.
•
If the vessel arrives before laydays commence, NOR should be tendered anyway in order to give the charterer the opportunity to accept the vessel earlier and also to use the 6 hours' notice time unless otherwise instructed by owners or charterers.
•
The rules for calculation of laytime vary considerably, therefore, the Captain should carefully read the clauses concerning notices, laytime and demurrage in the Charter Party in question and ensure "Notice of Readiness" is tendered at the right time, but to be safe, ensure that you tender immediately upon arrival load/discharge port. o
9.8
Please also ensure that the governing dates and hours are clearly stated in the "Statement of Facts". (Form TSM 017)
LAYTIME
Laytime means the period of time agreed between the parties in the Charter Party during which the owner will keep the vessel available for loading/discharging free of charge. Laytime normally commences 6 hours after Notice of Readiness has been given or when all fast, which ever occurs first but the Charter Party should in each case be consulted in order to have the correct basis for calculation of laytime, and runs until the cargo hose(s) has been disconnected. In certain instances, such as an unreasonably long time to complete paper work (in excess of 3 hours), laytime will continue until relevant documents are onboard, which therefore must be recorded. The following does not count as laytime: •
Sailing time from anchorage to first berth (all fast/moored)
•
Bunkering and possible steaming in this connection prior/after loading and discharging, (Unless using waiting time.)
•
Time used for deballasting, unless same carried out concurrent with cargo operations.
•
Stoppages ordered by ship for technical reasons.

•
It is important that the dates and hours governing the periods not counting as laytime are clearly stated in the statement of facts.
•
Further, the times and the calculation of laytime/demurrage should be included in the departure telex/cable from the loading/discharging port enabling TSM to make out the invoice as fast as possible. To expedite this kindly ask agents to telefax your completed Statements of Facts to us, alternatively ensure you mail signed copies of Statement express to Thome.
DEMURRAGE
If the vessel does not complete loading/discharging within the laytime allowed according to the Charter Party, the charterer must pay for the delay at an agreed rate. The vessel is then said to be working "on demurrage" which means that the laytime has expired. Once the vessel is on demurrage, time counts continuously unless otherwise provided in the Charter Party. The Captain must keep a current check on the laytime being used, and as soon as the laytime stipulated in the Charter Party has been used, the charterers, shipper, receiver, and Thome should be notified by telex that the vessel is on demurrage. The following wording should be used for this Notice: •
Without prejudice to owners claim for demurrage. "This serves to notify you that according to my calculation the laytime of (72) hours stipulated in the Charter Party has been used as of (date hour), wherefore the vessel is now operating on demurrage." Captain

CARGO QUANTITY AND DEAD FREIGHT
Advice on Cargo Quantity In Voyage Charter Parties the quantity agreed between charterers and owners may be described in various ways as per the following examples: •
•
"Full cargo 31,000 mton 5 percent moloo" (more or less in owners option): o
Owners guarantees vessel is able to load minimum 29450 mton.
o
Vessel may demand up to 32,550 m ton.
o
Possible deadfreight claim to be based on quantity of cargo demanded. If draft should restrict intake, loss of deadweight is for charterer's account. Intake restrictions because of limited cubic capacity is for owner's account.
"Part cargo 28,000 mton 5 percent moloo basis departure draft loading port 34 feet saltwater." o
•
"Minimum 30,000 mton - charterer's option to complete to full cargo". o
•
CONTROLLED
Owners guarantees vessel is able to load minimum 26,600 m ton. Vessel may demand cargo up to 34 feet draft saltwater. Possible deadfreight claim to be based on quantity of cargo demanded. If actual draft should restrict intake to less than 34 feet draft, loss of dead weight up to 34 feet is for charterer's account. Intake restrictions because of limited cubic capacity is for owner's account.
Owner guarantees vessel is able to load minimum 30,000 mton and charterer guarantees to supply at least this quantity. Possible deadfreight to be based on 30,000 mton. If draft should restrict intake below 30,000 mton, loss of deadweight is for charterer's account.
"Min/Max 30,000 mton" o
mton should be loaded as close as possible.
o
Owners guarantees that vessel is able to load 30,000 mton and charterer guarantees to supply the same quantity. Possible deadfreight to be based on 30,000 mton, loss of deadweight is for charterer's account. Revision: 01 Aug 2013 Approved by DPA/DMR Page 7 of 16

•
OMD Document No. 009 Charter Parties
If s.g. proves to be less than 0.74 then we have the possibility of claiming deadfreight for cargo short-loaded provided that the vessel is loaded to maximum cubic capacity. The vessel is to prepare a telex calculation/statement available for cargo multiplied by min. s.g. compared with actual loaded quantities i.e. vessel's figs and B/L figs.
Note that, in all the examples quoted, the charterer has a perfect right to load less than the fixed quantity, and loading instructions from charterer should always be followed to the letter. The significance of the fixed quantity is that the charterer is liable for deadfreight as outlined above.
Cargo Capacity - Advice to Loading Port. As freight is calculated on basis of the maximum tonnage within the limits of the fixture, it is very important to inform the port of loading of the vessel's total loading capacity. Please, therefore, include the following in arrival notices to the agent in every loadport: •
9.11
"Please inform suppliers: Vessel's Cargo Capacity :......... Metric tons equal to ......... long tons or cubic metres basis sg .......... at ......... degrees celsius estimated draft departure loadport .......... feet .........inches salt/freshwater estimated draft arrival discharge port ....... feet.....inches salt/freshwater"
STAY IN PORT •
Load Port Arrival o

Waiting at Anchorage (if applicable) o
•
•
CONTROLLED
The commencement of laytime requires tendering of Notice of Readiness. It is therefore essential that this notice is given at the earliest possible time preferably upon arrival at the pilot station unless this is obviously unreasonable in which case NOR should be tendered as soon as Master considers vessel to be in the right position.
If, after tendering NOR, vessel is instructed to wait at anchorage, vessel should anchor as near as possible to the eventual berth with minimum deviation from the direct line to berth. If the actual anchorage involves deviation of significance from the direct line to berth, Master should estimate how much longer time the shifting from anchorage to berth takes compared with direct proceeding to berth. The actual time to anchor will be performed in the "notice time".
Notice Time o
Most Charter parties will provide for the first 6 hours after tendering NOR as Charterers free time for preparations. This time will run continuously until used, unless the vessel is all fast in berth before expiry of 6 hours in which case laytime will commence from all fast in berth.
o
SHELLVOY 4 and BEEPEEVOY 2 "83" are slightly different from the other most used Charter parties.
Shifting from Anchorage to Berth
Revision: 01 Aug 2013 Approved by DPA/DMR Page 8 of 16
THOME SHIP MANAGEMENT PTE LTD
•
o
This time is Owners time and shall not count as laytime. It is important to observe that shifting is a word for movement and starts with actual departure from anchorage and ends with vessel being "all fast" in berth normally FWE. Many Time Sheets will show only time for pilot boarding and if departure from anchorage occur after pilot boarded, it is essential that time for departing anchorage is reflected in the Time Sheet, otherwise Charterers will want time deducted from an earlier time.
o
It should also be observed that all fast is the time of FWE or similar and not when gangway is down which is a different matter. Time of departing anchorage and time of all fast should always be quoted in messages to Owners. As shifting is Owners time it should be as fast as possible.
o
If the vessel leaves anchorage, but must slow down or interrupt the voyage because there is an unexpected delay for previous vessel to leave berth etc., a remark should be made in respect of duration of interruption/time lost in slowing down as Owners will then charge this lost time against Charterers.
Pre-loading Time o
•
•
Deballasting time is Owners time, but in practice Charterers will allow time to count if vessel has segregated ballast when deballasting effected concurrently with loading. Also large vessels being able to load while ballasting will earn laytime during deballasting if same is effected only while loading.
Segregated Ballast o
Since Charterers normally allow time to run while deballasting, if concurrent with loading, vessel should always await commencement of loading prior to deballasting. If vessel is allowed to berth, but cargo is not ready, then laytime will be interrupted if vessel commences deballasting while waiting for cargo.
o
Unless specifically instructed from shore vessels should never commence deballasting before loading commences, while alongside berth, unless shore are prepared to write N/A (NOT APPLICABLE) in column for deballasting in Time Sheet.
o
For segregated ballast vessel's Master should in addition try to avoid any references to deballasting in the "official" Time Sheet unless installation insists.
Ballast in Cargo Tanks o
CONTROLLED
Apart from eventual clearance of the vessel, this is a period of mixed activities such as shore/ship planning of cargo operation, connecting of ballast/cargo hoses, tank inspection when applicable. If these activities are permitted during clearance formalities, Master should not accept any reference in Time Sheet for delay caused by vessel's clearance by simply referring to "cargo preparation/work being effected without interruptions".
Deballasting o
•
OMD Document No. 009 Charter Parties
Such vessels cannot avoid interruption in laytime for deballasting, but it should always be observed that if vessel only carry minimum safe ballast quantity the interruption of laytime will be less than if no consideration given in respect of quantity with loss of earnings/extra expense as a result for Owners. If a vessel can deballast while loading and Master consider this to Revision: 01 Aug 2013 Approved by DPA/DMR Page 9 of 16
THOME SHIP MANAGEMENT PTE LTD
OMD Document No. 009 Charter Parties
be safe, then this should always be considered as it is extremely advantageous to Owners compared with separate deballasting. •
•
Time between De-ballasting & Commencement of Loading o
Most significant will be tank inspection for vessels without segregated ballast.
o
Many installations will try to identify "ship lining up" as being a delay. This is positively wrong as the "lining up" is an integral and unavoidable part of the preparation for loading, which does not qualify for interruption of laytime and will often be carried out concurrently with other charterers' activities such as tank inspection. Any reference to lining up should preferably be avoided. The time between deballasting/commencement of loading should be exclusively laytime/charterers time.
Loading o
•
Time between Loading and Disconnecting of Hoses o
•
•
Disconnecting of hoses is Charterers' time and when hoses disconnected vessel is considered to be fully at Owner's disposal. This is normally the time when laytime ends. This time should always be quoted in messages to Owners.
Time between Hoses Off and Sailing o
This time is Owner's time with one important consideration to be made.
o
After loading there will be a period of establishing the loaded quantity to be inserted in the Bills of Lading. There is also some time necessary for laboratory tests etc., which may take considerable time. As vessel itself will require some time herself before she is ready to sail it has been accepted that Charterers are not delaying vessel if they present cargo documents within "reasonable time".
o
"Reasonable time" has been identified as 2 hours, any additional time can be charged as detention of the vessel.
o
Master should, therefore, always quote time when receiving cargo documents in messages to Owners. Likewise, if vessel leaves berth and awaits cargo documents at anchorage the "interruption" of the voyage i.e. time between stop and receipt of document is detention. Such time should always be quoted in messages to Owners. If cargo documents needs to be checked before signing so that there will be significant time between received and signed, then time for signature should be reported.
o
Ideally, all times specifically mentioned as important should also be reflected in the Statement of Facts, and Master should endeavour to have times inserted.
Discharge Port Arrival o
CONTROLLED
This time spent for ullaging, sampling etc. is Charterers' time.
Disconnecting of Hoses o
•
This is Charterers' time unless there is something wrong with the vessel causing delay.
The commencement of laytime requires tendering of Notice of Readiness. It is therefore essential that this notice is given at the earliest possible time Revision: 01 Aug 2013 Approved by DPA/DMR Page 10 of 16

It is important to observe that shifting is a word for movement and starts with actual departure from anchorage and ends with vessel being "all fast" in berth normally FWE. Many Time Sheets will show only time for pilot boarding and if departure from anchorage occurs after pilot boarded, it is essential that time for departing anchorage is reflected in the Time Sheet, otherwise Charterers will want time deducted from a previous time.
o
It should also be observed that all fast is the time of FWE and not when gangway is down, which is a different matter. Time of departing anchorage and time of all fast should always be quoted in messages to Owners. As shifting is Owner's time it should be as fast as possible.
o
If the vessel leaves anchorage, but must slow down or interrupt the voyage because there is an unexpected delay for previous vessel to leave berth etc., a remark should be made in respect of duration of interruption/time lost in slowing down as Owners will then charge this lost time against Charterers.
Pre-discharging Time o
•
Apart from eventual clearance of the vessel, this is a period of mixed activities such as shore/ship planning of cargo operation, connecting of cargo hoses, sampling, ullaging etc. If these activities are permitted during clearance formalities, Master should not accept any reference in Time Sheet for delay caused by vessel's clearance by simply referring to "cargo preparation/work being effected without interruptions".
Discharging o
CONTROLLED
If, after tendering NOR, vessel is instructed to wait at anchorage, vessel should anchor as near as possible to the eventual berth with minimum deviation from the direct line to berth. If the actual anchorage involves deviation of significance from the direct line to berth, Master should estimate how much longer time the shifting from anchorage to berth takes compared with direct proceeding to berth. The actual time to anchor will be performed in the "notice time".
This is Charterers' time unless there is something wrong with the vessel causing delay.

Please observe carefully references to pumping warranties under DEFINITIONS for normal clean/dirty voyages performed on WORLDSCALE TERMS. For such voyages a Pumping log should always be kept and copy mailed to Owner's office together with Time Sheet and NOR. For vegetable oils, chemicals, molasses etc. There are different terms which are dealt with under DEFINITIONS.

IMPORTANT: If discharging appear to be completed at a time when sailing will be delayed because of tide/no night manoeuvring, please bear following in mind:
o
If discharging completed 0030, hoses disconnected 0100, earliest sailing 0700 the time between 0100 and 0700 will be Owner's account. If discharging completed 0630, hoses disconnected 0700, then time to 0700 will be Charterers' account.
o
Therefore, if pressure at manifold is maintained at, say, 9 kg and discharging completed 0030, it would be better to perform at 7,5 kg (Which is still within the warranty and complete at 0630 as then all time will be paid by Charterers rather than 6 hours waiting from 0100 0700 at Owner's expense.
o
Such considerations should be kept in mind in order to minimize time at Owner's expense if vessel can slow down without protest from the installation. This sensitive matter is entirely the discretion of Master.
o
Please observe reference to COW Booster pumps, ballasting, Line displacement, RPM, Volume, Non concurrent discharge etc.
Ballasting o
Any references to ballasting should preferably be avoided. If unavoidable, Master should only mention commencement of ballasting at the earliest when hoses disconnected as any ballasting before disconnecting hoses has been carried out on Charterers' time concurrently with discharging.
o
If time for ballasting must be shown prior to disconnecting, Master should make remark on Time Sheet that ballasting did not interfere with discharging. See remarks under DEFINITIONS. This is less important after ASBA II was abolished.
Time between Discharging and Disconnecting of Hoses o
•
Disconnecting of hoses is charterers' time and when hoses disconnected, vessel is considered to be fully at Owner's disposal. This is normally the time when laytime ends. This time should always be quoted in messages to Owners.

OMD Document No. 009 Charter Parties
OFF HIRE
All Time Charter parties contain, in the main body of the document, an "Off-Hire Clause" whereby the ship's Owners, or Owner's Agents, may become liable for any deficiencies, or defaults on the part of the vessel, its crew and/or equipment. •
These penalties may be incurred by any kind of vessel, regardless of type or trade, i.e. tanker, bulker, dry cargo, etc. on Time Charter.
•
Of particular concern are the agreed, or stated, performance criteria. Vessels may incur penalties for both over-performing and under-performing. The exact wording of all clauses, especially the Rider clauses should be carefully examined to ensure that vessels perform according to the terms of their C/P's.
•
It is the responsibility of the Marine Manager to review all C/P and advise Fleet Group Managers, Superintendents and Masters during pre-joining meetings of the terms of the C/P for the respective vessel.
•
The Marine Manager should keep all Off-Hire records for the Thome managed fleet. He is also responsible for reviewing Off-Hire and performance claims received by charterers. The Marine Manager will report Off-Hire figures to Chief Operating Officer every quarter on a specific format.
Dry-docking In the duration of a Time Charter, Owners have the right and obligation to drydock the vessel at regular intervals within time limits mutually agreed upon. Charterers require notice of the Owners intention to dock the vessel. Charterers may nominate a port for delivery of the ship for docking in which case the vessel will be off-hire from time of arrival at such port until drydocking is completed and vessel ready in every respect to resume service at that port. This may vary pending the type of C/P. •
The Marine Manager is to advise Fleet Group Managers and Superintendents of the relevant Off-Hire clause to be applied in connection with each docking.
•
If the Owners require the vessel, instead of proceeding to the offered port, to carry out a periodical docking at a port of their own choice, the vessel will be offhire from the time she is released to proceed to the special port until she next presents for loading in accordance with Charterers' instructions. It is usual for charterers to credit owners, in this instance, with the time which would have been taken on the passage at the service speed had the vessel not proceeded to drydock. (Shelltime 4).
On & Off-Hire / Re-Delivery Surveys •
On-Hire Surveys are carried out at the time of the vessel's delivery to Charterers, usually at the commencement of a Time Charter.
•
Off-Hire Surveys are carried out prior to re-delivery of the vessel, from the Charterers back to the Owners, on the last voyage.
•
On/Off-Hire surveys are usually held jointly by Owners and Charterers, by one independent surveyor, with the costs being shared equally. However, it cannot be over stressed that the onus is on the Master, as Owners' Representative, to carefully check the C/P clauses in every case and to ensure that remaining fuel and diesel oil represent a true account of the facts, in the Owners' best interests.

•
Each Superintendent is to keep a record of "Off-Hire" time for his vessels, based upon information received from the ships via TSM Form 036: "Off-Hire Statement". A copy shall be given to the Marine Manager, who shall keep full statistics and records for the entire Thome managed fleet.
•
All times, dates and R.O.B.'s should be as accurate as possible. I.e. two decimal places. An explanation should accompany each report.
•
A copy of each Off-Hire report is to be passed to the Marine Manager for his analysis, comments and filing. Every quarter an “Off-Hire” report covering the total fleet is to be prepared by the Marine Manager and submitted to Chief Operating Officer.
•
Notification and explanations of any "Off-Hire" periods are to be immediately sent to the Owner by the Fleet Group Managers and thereafter to be included in the Quarterly Management Report.
CHECKING AND SIGNING OF STATEMENT OF FACTS
The Statement of Facts is a very important document, and as such merits special attention. For tankers, Form TSM 17 shall be used. The Laytime calculation and hence demurrage or dispatch on voyage charters, and also off-hire due to winch breakdown, or other causes attributed to the vessel, when on time-charter are based on the information shown on the Statement of Facts. Hence, it is of the utmost importance to record accurately, in your vessel's log book, all the activities taking place such as: •
Date and time of arrival at roads and in port (at berth)
•
Date and time Notice of Readiness was tendered and accepted
•
Date and times that loading or discharging commenced, number of gangs, and at what holds cargo work is performed.
•
Dates and times of any interruptions such as bad weather, Stevedore meal times, breakdown of shore gear, breakdown of ship's gear, strike by stevedores, gang availability, cargo availability etc.

NAVIGATION EQUIPMENT Purpose To specify requirements for use and maintenance of Bridge Navigation Equipment
Application All vessels
Responsibility Master Navigating Officers Watch Standers
10.1
GENERAL
It is vitally important that watch-keeping officers are completely familiar with all navigation equipment on board. Navigation equipment should be checked each watch by the Officer of the Watch to ensure that it is fully operational. Defects should be recorded and brought to the attention of the Master. It is of prime importance that bridge watch-keeping officers acquaint themselves with the contents of operating manuals for equipment, particularly with regard to the setting up of controls and the procedure to be followed in the event of a fault. The Master should ensure that regular maintenance of all navigational equipment is carried out in accordance with manufacturers' instruction manuals. The upkeep and maintenance of individual items of navigational equipment should be the responsibility of a nominated officer, and their operational status should be recorded. Thome Ship Management requires that any equipment (whether personal or shipboard) which is not approved and / or not included in the Cargo Ship Safety equipment Form E cannot be used for navigation. This would include but not be limited to personal laptops, GPS units or ECDIS systems (non-approved). In case the Vessel has been provided with extra navigation aids, they should be appropriately marked “Caution! Not to be used for Navigation”
10.2
RADAR AND AUTOMATIC RADAR PLOTTING AIDS (ARPA)
The Master should ensure that at least one radar is available for use by the Officer of the Watch: •
As an instrument for fixing and monitoring positions parallel indexing, etc;
•
As an aid for assessing the risk of collision;
•
For practicing plotting, etc.
The radar should be switched on in sufficient time before it is required, to establish that it is operating correctly and to adjust it to obtain optimum performance If weather conditions are such that visibility may deteriorate, the ship's radar should be operating at all times to monitor for START signals and especially in reduced visibility. The display should be observed as frequently as the prevailing circumstances require. The life and operating efficiency of radar sets are affected less by continuous operation than by frequent switching on and off. If two sets are fitted, at least one should be operating at all times. CONTROLLED
Revision: 14 Nov 2012 Approved by DPA/DMR Page 1 of 20
THOME SHIP MANAGEMENT PTE LTD
OMD Document No. 010 Navigation Equipment
The performance of the radar equipment should be checked before sailing and at least once every four hours while radar watch is being maintained. Where fitted, a performance monitor should be used for this purpose. Whenever the ship's radar is switched on and at the commencement of each watch if the radar is in operation, the trace should be checked and, if necessary, adjusted to ensure that it is rotating about the centre of the display. At the same time the alignment of the heading marker should be checked as shown in the operating manual. When using radar for fixing or monitoring the ship's position the following should be checked: •
the radar's overall performance
•
the identity of the fixed objects observed
•
gyro error and the accuracy of the heading marker
•
the accuracy of the variable range marker, bearing cursor and fixed range rings
•
On true motion, that the display is correctly ground stabilised
When operating ARPA, the use of audible operational warning signals to denote that a target has closed to a particular range, or that it is transiting a selected guard zone, does not relieve the Master, or the Officer of the Watch, of the duty to maintain a proper lookout by all available means. When the ARPA is operating in an automatic acquisition mode, such warning devices should be used with caution, especially when in the vicinity of inconspicuous radar targets. Users should familiarise themselves with the effect of errors on the automatic tracking of targets as described in the ARPA operating manual. It is important that the speed input for all anti-collision plots on radar or ARPA should be speed through the water and not speed over the ground. The use of speed over the ground can lead to errors especially when predicting the effect of intended manoeuvres. If speed input to the radar or ARPA is from a Doppler log, it should be noted that the Doppler log may automatically switch from water tracking to ground tracking. In such cases a warning notice must be posted advising officers of the need for manual speed input. When reduced visibility is encountered or expected, a radar plot should be promptly established. A reduction of speed may allow more time for plotting. The high standard of proficiency necessary for the use of radar in reduced visibility will not be achieved unless regular anti-collision and plotting practice is carried out. The Master should ensure that all Officers of the Watch practice radar plotting regularly in clear weather, particularly when approaching coastal waters after a long ocean passage.
10.3
STEERING GEAR AND AUTOMATIC PILOT
The Officer of the Watch should comply with the requirements for the operation and testing of the steering gear and the automatic pilot contained in SOLAS Chapter V. All Deck Watch Officers and Helmsmen must be thoroughly familiar with the proper method of changing over from one steering mode to another. The changeover procedures for each vessel shall be posted close to the helm for ready reference. Any change of steering mode must be supervised by the Deck Watch Officer. Helmsmen are not to make any steering mode changeover, interfere with, or operate the steering mode controls unless supervised by the Deck Watch Officer. The Master shall be responsible for training all Deck Watch Officers and Helmsmen in proper procedures for changing over the steering mode. The off-course alarm, when fitted, should be adjusted to suit the prevailing weather conditions. The alarm should be in use at all times when under automatic steering. If the alarm becomes CONTROLLED

unserviceable the Master should be informed immediately. The use of an alarm does not in any way relieve the Officer of the Watch from frequently checking the course being steered. The auto pilot alarm must be tested at noon each day at sea and prior to entering restricted waters. These tests shall be logged as completed.\
USCG Marine Safety Bulletin - Steering Tests Prior To Entering US Waters 33 Code of Federal Regulations 164.25 (please see below)states no person may cause a vessel to enter into or get underway on the navigable waters of the United States unless no more than 12 hours before entering or getting underway, the main steering gear is tested from the alternative power supply (emergency generator), if installed.
Details Masters and/or operators of vessels are reminded that it is their responsibility to ensure that the vessel is in compliance with 33 Code of Federal Regulations part 164 (Navigation Safety Regulations) prior to entering or being operated on the navigable waters of the United States. Failure to ensure compliance with these regulations subjects the vessel to a civil penalty for each violation. However, it is not the Captain of the Port New Orleans' intention to issue monetary fines, just gain compliance with the rules and regulations to safely operate on the navigable waters of the United States. Title 33: Navigation and Navigable Waters - PART 164—NAVIGATION SAFETY REGULATIONS § 164.25 Tests before entering or getting underway. (a) Except as provided in paragraphs (b) and (c) of this section no person may cause a vessel to enter into or get underway on the navigable waters of the United States unless no more than 12 hours before entering or getting underway, the following equipment has been tested: (1) Primary and secondary steering gear. The test procedure includes a visual inspection of the steering gear and its connecting linkage, and, where applicable, the operation of the following: •
Each remote steering gear control system
•
Each steering position located on the navigating bridge
•
The main steering gear from the alternative power supply, if installed
•
Each rudder angle indicator in relation to the actual position of the rudder
•
Each remote steering gear control system power failure alarm
•
Each remote steering gear power unit failure alarm
•
The full movement of the rudder to the required capabilities of the steering gear.
(2) All internal vessel control communications and vessel control alarms. (3) Standby or emergency generator, for as long as necessary to show proper functioning, including steady state temperature and pressure readings. (4) Storage batteries for emergency lighting and power systems in vessel control and propulsion machinery spaces. (5) Main propulsion machinery, ahead and astern. (b) Vessels navigating on the Great Lakes and their connecting and tributary waters, having once completed the test requirements of this subpart, are considered to remain in compliance until arriving at the next port of call on the Great Lakes.

(c) Vessels entering the Great Lakes from the St. Lawrence Seaway are considered to be in compliance with this sub-part if the required tests are conducted preparatory to or during the passage of the St. Lawrence Seaway or within one hour of passing Wolfe Island. (d) No vessel may enter, or be operated on the navigable waters of the United States unless the emergency steering drill described below has been conducted within 48 hours prior to entry and logged in the vessel logbook, unless the drill is conducted and logged on a regular basis at least once every three months. This drill must include at a minimum the following:
10.4
•
Operation of the main steering gear from within the steering gear compartment.
•
Operation of the means of communications between the navigating bridge and the steering compartment.
•
Operation of the alternative power supply for the steering gear if the vessel is so equipped.
GYRO AND MAGNETIC COMPASSES
It is recommended that the gyro compass should be run continuously. Should it stop for any reason, it should be restarted and subsequently checked before use to ensure it has 'settled' and is reading correctly. Where there is a scheduled power outage then switch the gyro off to protect it. After any scheduled or unscheduled power outage the gyro must be checked frequently to ensure it has settled. Latitude and speed corrections should be applied to the gyro compass by a designated officer. Repeaters should be synchronised with the gyro at least once a watch. The gyro alarm should be checked daily. As a safeguard against the gyro and gyro repeaters wandering, frequent checks should be made between the magnetic and gyro compasses. Care should be taken to monitor errors induced by the ship's manoeuvring as such errors can reach 5 degrees or more. As far as practicable, compass errors should be checked and recorded each watch using either azimuth or transit bearing, or by comparison with the magnetic compass. All liquid magnetic compasses should be checked regularly for air bubbles. They should be covered at all times when not in use. Gyro & Magnetic compasses are to be serviced / calibrated by a qualified technician / Compass Adjuster once every year. Magnetic compasses will be adjusted whenever significant deviation occurs. Where fitted as a standby system, the magnetic compass control of the automatic pilot should be tested and exercised not less than once a week and in clear visibility.
10.5
CHRONOMETERS / CLOCKS
Where necessary, chronometers should be wound daily at the same time and checked with a radio time signal. The chronometer error should be recorded on the ship's chronometer rate card and the Master informed of any unusual change in rate. Where quartz or electronic chronometers are fitted, batteries should be changed at the manufacturer's recommended intervals and a record kept. Prior to getting underway, as part of the Bridge Equipment Tests, clocks shall be compared and synchronised, and the synchronisation entered in the Deck Logbook. Bridge and engine room clocks shall also be synchronised daily at noon and prior to arrival. The engine room must be notified whenever necessary to ensure that engine room and Bridge clocks are synchronised. When it is necessary to advance or retard vessel clocks, all clocks shall be advanced or retarded at the same time, i.e. the Bridge clock, chartroom clock and engine room clock shall always indicate the CONTROLLED

same time. Time zone changes, and any time changes due to Daylight Savings Time, shall be logged when made.
10.6
ECHO SOUNDERS
The echo sounder should be used, both when making a landfall and in coastal waters, and particularly in areas where charted depths must be treated with caution. When approaching sounding depths, the echo sounder should be switched on in ample time, and the operator should ensure that a zero mark is recorded. The echo sounder should be operated on all ranges and scales regularly until a sounding is obtained. Care should be taken to check whether units of soundings on the echo sounder are different from those on the chart in use. The time of crossing the more important depth contours should be recorded in the deck log, with the distance recorder reading Whenever the echo sounder is used a notation should be made on the recording paper of the vessel position and time. SOLAS requires the echo sounder be checked against known or charted depths on each and every voyage.
10.7
SPEED / DISTANCE RECORDERS
The speed/distance recorder should be operated as soon as it is practicable to do so. Readings of distance through the water should be entered in the deck log at the end of each watch and at times of establishing positions (where these are recorded in the deck log) and when course or speed is altered. Readings should be entered on the chart alongside the ship's position.
10.8
ELECTRONIC POSITION FIXING AIDS
Electronic position fixing aids shall be tested and aligned prior to getting underway. Electronic position fixing aids should be employed in conjunction with other available aids to navigation. The Officer of the Watch should be thoroughly familiar with their use and limitations, including the application of corrections to readings. The manufacturer's operating handbook and current navigational warnings should be consulted to ensure that proper corrections are applied. GPS positions are referenced to the World Geodetic System 1984 Datum (WGS 84) and it is recommended that the GPS receiver is maintained referenced to that datum. This may not be the same as the horizontal datum of the chart in use, meaning that the position when plotted may be in error. The receiver may convert the position to other datum; however these facilities should be used with caution. In this case the observers must ensure that they are aware of the datum of the displayed position. Where the difference in datums is known, a note on the chart provides the offset to apply to positions referenced to WGS 84 for plotting on the chart, but where this offset is not provided, the accuracy of the plotted position should be treated with caution. DGPS positions are normally referenced to WGS 84 though regional datums, corresponding to WGS 84, may be used [e.g. North American Datum 1983 (NAD 83) in the USA] and European Terrestrial Reference System 1989 (ETRS 89). Many areas of the world have not been surveyed to modern standards hence the positional accuracy of the charted detail on the paper chart, Raster chart or ENC may not be as accurate as the GNSS CONTROLLED

(Global Navigation Satellite System) receiver derived position. Masters and Navigating Officers should allow a sensible safety margin to account for any such discrepancies. The prudent navigator should never rely totally on GNSS navigation and should regularly cross check the ship’s position using other means particularly in areas where the charts are based on old surveys. Navigating Officers must read the note on satellite-derived positions on the Admiralty charts for more information. Further information can be found in the Mariner’s Handbook (NP 100) and in Annual Summary of Admiralty Notices to Mariners, No19. Volume 2 of The Admiralty List of Radio Signals published by UKHO contains full descriptions of all GNSS systems, with notes on their correct use and limitations. Also included are descriptions and examples of over-reliance on GNSS, and a full account of the problems caused by differing horizontal datums. All Masters and navigational Officers using satellite navigation systems are strongly advised to study the information and follow the advice contained in this publication.
10.9
GENERAL ALARM
The Deck Watch Officer is responsible for and must test the vessel's General Alarm system prior to getting underway, at noon each day at sea, and prior to entering restricted waters. These tests shall be logged as completed.

RADIOS
Prior to getting underway, Bridge V.H.F. radios shall be checked to ensure that they are operational on the proper channel(s). •

The AIS operational
Bridge radio equipment use should be restricted to distress traffic, navigational safety, and official Company business. Transmissions shall be kept to a minimum. With the Master's permission, this equipment may be used for public correspondence. Bridge-to-Bridge VHF Channel 13 use is mandatory for all vessels in U.S. waters. Deck Watch Officers must feel free to use Bridge radio equipment as needed, especially to determine other vessels' manoeuvring intentions and to announce their own vessel's intentions. All Deck Watch Officers must know the different VHF channels used for the services they may need, whether vessel-to-vessel or otherwise. A continuous listening watch shall be maintained at sea on the approved distress frequencies.
Use of VHF as Collision Avoidance Aid Channel 13 is designated for use on a worldwide basis as a navigation safety communication channel, primarily for intership navigation safety communications. Although VHF at sea makes an important contribution to navigation safety, its misuse causes serious interference and, in itself, becomes a danger to safety at sea •
CONTROLLED
There have been a significant number of collisions where subsequent investigation has found that at some stage before impact, one or both parties were using VHF radio in an attempt to avoid collision. The use of VHF radio in these circumstances is not always helpful and may even prove to be dangerous.

•
At night, in restricted visibility or when there are more than two vessels in the vicinity, the need for positive identification is essential but this can rarely be guaranteed. Uncertainties can arise over the identification of vessels and the interpretation of messages received. Even where positive identification has been achieved there is still the possibility of a misunderstanding due to language difficulties however fluent the parties concerned might be in the language being used. An imprecise or ambiguously expressed message could have serious consequences.
•
Valuable time can be wasted whilst mariners on vessels approaching each other try to make contact on VHF radio instead of complying with the Collision Regulations. There is the further danger that even if contact and identification is achieved and no difficulties over the language of communication or message content arise, a course of action might still be chosen that does not comply with the Collision Regulations. This may lead to the collision it was intended to prevent.
Although the practice of using VHF radio as a collision avoidance aid may be resorted to on occasion, for example in pilotage waters, the risks described in this circular should be clearly understood and the Collision Regulations complied with. Due to inherent limitations, Thome Ship management does not advocate Use of VHF as a Collision Avoidance Aid
VHF Communication Technique Preparation Before transmitting, think about the subjects which have to be communicated and, if necessary, prepare written notes to avoid unnecessary interruptions and ensure that no valuable time is wasted on a busy channel.
Listening Listen before commencing to transmit to make certain that the channel is not already in use. This will avoid unnecessary and irritating interference.
Discipline VHF equipment should be used correctly and in accordance with the Radio Regulations. The following in particular should be avoided: •
Calling on channel 16 for purposes other than distress, and very brief safety communications, when another calling channel is available
•
Non - essential transmissions, e.g. needless and superfluous signals and correspondence
•
Communications not related to safety and navigation on port operation channels; communication on channel 70 other than for Digital Selective Calling
•
Occupation of one particular channel under poor conditions
•
Transmitting without correct identification
•
Use of offensive language

Communications with coast stations On VHF channels allocated to port operations service, the only messages permitted are restricted to those relating to the operational handling, the movement and safety of ships and, in emergency, to the safety of persons, as the use of these channels for ship-to-ship communications may cause serious interference to communications related to the movement and safety of shipping in port areas. Instructions given on communication matters by shore stations should be obeyed. Communications should be carried out on the channel indicated by the shore station. When a change of channel is requested, this should be acknowledged by the ship.
Communications with other ships VHF Channel 13 is designated by the Radio Regulations for bridge to bridge communications. The ship called may indicate another working channel on which further transmissions should take place. The calling ship should acknowledge acceptance before changing channels. The listening procedure outlined above should be followed before communications are commenced on the chosen channel.
Distress communications Distress calls/messages have absolute priority over all other communications. When heard, all other transmissions should cease and a listening watch should be kept. Any distress call/message should be recorded in the ship’s log and passed to the master. On receipt of a distress message, if in the vicinity, immediately acknowledge receipt. If not in the vicinity, allow a short interval of time to elapse before acknowledging receipt of the message in order to permit ships nearer to the distress to do so.
Addressing The words “I” and “You” should be used prudently. Indicate to whom they refer. Example of good practice:

USE AND LIMITATIONS OF AIS
The Automated Identification System (AIS) shall be kept operational at all the times unless and except when safety considerations such as during loading and discharging of volatile cargo in bulk, prohibit it’s continued operation. Once the cargo is loaded or discharged, the AIS will be reactivated. The Ship Security Officer shall inform the Port Facility Security Officer immediately before and after the activation and reactivation of the AIS respectively. Relevant information such as Static data, Voyage related data and Dynamic data shall be checked by use of Daily and Pre departure Bridge Checklists ( OPS – Part B : Deck Checklist )
Use and Limitations of AIS in Navigation •
AIS is designed to be able to provide additional information to existing Radar or ECDIS displays
•
AIS provides identification of targets together with static and dynamic information
•
This information must be used with caution noting the following important points:
•
Collision avoidance must be carried out in strict compliance with the Collision Regulations. There is no provision in the Collision Regulations for use of AIS information therefore decisions should be taken based primarily on visual and / or radar information.
•
The use of VHF to discuss actions to take between approaching ships is fraught with danger and is discouraged. The identification of a target by AIS does not remove the danger. Decisions on collision avoidance should be made strictly according to the Collision Regulations.
•
Not all ships will be fitted with AIS, particularly small craft and fishing boats. Other floating objects which may give a radar echo will not be detected by AIS.
•
AIS positions are derived from the target’s GNSS position. (GNSS = Global Navigation Satellite System, usually GPS). This may not coincide exactly with the target.
•
Faulty data input to AIS could lead to incorrect or misleading information being displayed on other vessels. Mariners should remember that information derived from radar plots relies solely upon data measured by the own-ship’s radar and provides an accurate measurement of the target’s relative course and speed, which is the most important factor in deciding upon action to avoid collision. Existing ships of less than 500 gt. which are not required to fit a gyro compass are unlikely to transmit heading information.

OMD Document No. 010 Navigation Equipment
A future development of AIS is the ability to provide synthetic AIS targets and virtual navigation marks enabling coastal authorities to provide an AIS symbol on the display in any position. Mariners should bear in mind that this ability could lead to the appearance of “virtual” AIS targets and therefore take particular care when an AIS target is not complemented by a radar target. AIS will sometimes be able to detect targets which are in a radar shadow area.
Limitations of AIS The officer of the watch should always be aware that other ships, in particular leisure craft, fishing boats and warships, and some coastal shore stations including Vessel Traffic Service (VTS) centres, might not be fitted with AIS. The Officer on watch should always be aware that other ships fitted with AIS as a mandatory carriage requirement may switch off AIS under certain circumstances by professional judgement of the master. In other words, the information given by the AIS may not be a complete picture of the situation around the ship. The users must be aware that transmission of erroneous information implies a risk to other ships as well as their own. The users remain responsible for all information entered into the system and the information added by the sensors. The accuracy of the information received is only as good as the accuracy of the AIS information transmitted. The Officer on watch should be aware that poorly configured or calibrated ship sensors (position, speed and heading sensors) might lead to incorrect information being transmitted. Incorrect information about one ship displayed on the bridge of another could be dangerously confusing. If no sensor is installed or if the sensor (e.g. the gyro) fails to provide data, the AIS automatically transmits the ‘not available’ data value. However the built in integrity check cannot validate the contents of the data processed by the AIS. It would not be prudent for the Officer on watch to assume that the information received from the other ship is of a comparable quality and accuracy to that which might be available on own ship.
Use of AIS in Collision Avoidance Situations The potential of AIS as an anti collision device is recognised and AIS may be recommended as such a device in due time. Nevertheless, AIS information may be used to assist collision avoidance decision making. When using the AIS in the ship to ship mode for anti collision purposes, the following precautionary points should be borne in mind: •
AIS is an additional source of navigational information. It does not replace, but supports, navigational systems such as radar target tracking and VTS
•
The use of AIS does not negate the responsibility of the Officer on watch to comply at all times with the Collision Regulations.
The user should not rely on AIS as the sole information system, but should make use of all safety relevant information available. The use of AIS on board ship is not intended to have any special impact on the composition of the navigational watch, which should be determined in accordance with the STCW Convention. Once a ship has been detected, AIS can assist tracking it as a target. By monitoring the information broadcast by that target, its actions can also be monitored. CONTROLLED

Changes in heading and course are, for example, immediately apparent, and many of the problems common to tracking targets by radar, namely clutter, target swap as ships pass close by and target loss following a fast manoeuvre, do not affect AIS. AIS can also assist in the identification of targets, by name or call sign and by ship type and navigational status.
Switching Automatic Identification System (AIS) to Low Power Transmission Mode during cargo operation In compliance to AIS carriage requirement and Guide to onboard operational use of AIS adopted by IMO resolution A.917(22) dated 25 Jan 2002, all vessels are equipped with an AIS onboard. In order to reduce the overall radio transmission from the vessel during cargo operations, please note that the AIS is to be switched to "low power emission" mode at Oil Terminals, Single Buoy Mooring (SBM), or Ship To Ship (STS) locations, unless otherwise as spelled out by the Terminal Operator at the time of cargo operation. In the event that the AIS is unable to be switched to "low power emission" mode, due to limitations of “password entry” or if the unit lowest power is 2W, Terminal Operator's permission shall be sought prior to switching off the AIS, and it shall be switched on upon completion of cargo operation and prior to vessel's departure from the Terminal.
AIS Maintenance Records must be available to Class Although AIS maintenance may be included in security equipment maintenance records incorporated into TSM Form 178-1, it must be noted that AIS maintenance is not confidential and must be available for Class review. The preferred method of record keeping is by inclusion in the AMOS Planned Maintenance System. All vessels with computerized maintenance systems should ensure AIS Maintenance, in accordance with the makes instructions is entered. •
Pilot plugs are required to be fitted in the AIS for use by the Pilot when entering and leaving port
Further guidelines and details of Handling of AIS could be found in respective AIS Instruction Manual on board and should be fully complied with at all the times. Guidelines of AIS is given in ISGOTT 5th Edition 4.8.4 and 26.4 – “Guidelines to Completing Checklist Item 40”.
Use of AIS for Collision Avoidance It is guided that for the purpose of collision avoidance, ‘Speed through water’ is used. USCG holds up vessel over the non – availability of ‘Speed over Ground’ in the Automatic Identification System USCG insists that the Speed input into the system should be ‘Speed over Ground’, prior allowing the vessel to enter the Mississippi river. There had been reports from Vessels calling United States that the Port/ Pilot and VTS Authorities have insisted on ‘Speed over Ground’ input into the AIS. Hence it is recommended that for all Ships calling US waters should change-over their AIS to transmit the ‘Speed over ground’. In case the equipment is not designed as such, please contact your technical superintendent for further advice. Please post a caution notice near the AIS unit, cautioning for switch-over to Speed over ground when entering US Waters When the vessels are calling US waters and the AIS is displaying ‘Speed over ground’, the Navigating officers / Masters are cautioned against using the data from the AIS for the purpose of collision avoidance (e.g. data feed to ARPA / relying on CPA-TCPA as calculated) Use of AIS while transiting High Risk Areas CONTROLLED

VOYAGE DATA RECORDERS
Voyage Data Recorder, or VDR, is a data recording system designed for all vessels required to comply with the IMO Res.A.861(20) and SOLAS in order to collect data from various sensors on board the vessel. Ships of 3000 gross tonnage and upwards constructed on or after 1 July 2002 must carry voyage data recorders (VDRs) to assist in accident investigations, under regulations adopted in 2000, which entered into force on 1 July 2002. Like the black boxes carried on aircraft, VDRs enable accident investigators to review procedures and instructions in the moments before an incident and help to identify the cause of any accident. The Voyage Data Recorder, or VDR, is a data recording system designed for all vessels required to comply with the IMO's International Convention SOLAS Requirements (IMO Res.A.861(20)) in order to collect data from various sensors on board the vessel. It then digitizes, compresses and stores this information in an externally mounted protective storage unit. The protective storage unit is a tamper-proof unit designed to withstand the extreme shock, impact, pressure and heat, which could be associated with a marine incident (fire, explosion, collision, sinking, etc). The protective storage unit may be in a retrievable fixed unit or free float unit. As per SOLAS requirement the time for which all stored data item are retained should be at least 12 hours (in some models more than 12 hrs). Data items which are older than the time specified by the makers may be over written with new data. The stored data in protected unit can be recovered and replayed by the authorities or ship owners for incident investigation. The VDR also provides an interface to download and playback the data for investigation purposes. Although the primary purpose of the VDR is for accident investigation after the fact, there can be other uses of recorded data for preventive maintenance, performance efficiency monitoring, heavy weather damage, accident avoidance and training purpose to improve safety and reduce running cost. In the event of any incident on board ship where it is possible to continue the voyage after the incident the master should take a back up of the data as per the instruction from maker’s and in consultation with the Marine Manager or the Office Emergency Response Team and in any case in the event of a major incident should switch off the VDR in order to save the data from being overwritten. As per SOLAS, if the ships emergency source of electrical power fails the VDR should continue to record the Bridge audio from the dedicated reserve source of power for a period of 2 hours. At the end of this 2 hour period recording should cease automatically. The Master should ensure the proper instructions are displayed near the VDR as follows: •
Recording time of the VDR
•
Source of Power including emergency source
•
In case of incidents
•
CONTROLLED
o
Master to contact Marine Manager or Office Emergency Response Team to take specific instructions regarding the time when to stop the VDR
o

The OOW should monitor the VDR /S-VDR is functioning properly and in case of any alarms of the system should inform the Master immediately. In the case of any faults in the system which cannot be rectified, the master should immediately contact the office so as to provide the vessel with the necessary assistance from equipment makers Revision: 14 Nov 2012 Approved by DPA/DMR Page 13 of 20

•
An entry should be made into the log book in the case of any faults in the system stating the time of failure and the alarm condition and further on rectification of the fault
•
The maintenance of the VDR/S-VDR is to be carried out as per equipment maker’s instructions including annual servicing of the equipment
Simplified VDRs The S-VDR is not required to store the same level of detailed data as a standard VDR, but nonetheless should maintain a store, in a secure and retrievable form, of information concerning the position, movement, physical status, command and control of a vessel over the period leading up to and following an incident. To assist in casualty investigations, cargo ships, when engaged on international voyages, shall be fitted with a VDR which may be a simplified voyage data recorder (S VDR) as follows: •
In the case of cargo ships of 20,000 gross tonnage and upwards constructed before 1 July 2002, at the first scheduled dry-docking after 1 July 2006 but not later than 1 July 2009;
•
In the case of cargo ships of 3,000 gross tonnage and upwards but less than 20,000 gross tonnage constructed before 1 July 2002, at the first scheduled drydocking after 1 July 2007 but not later than 1 July 2010; and
Administrations may exempt cargo ships from the application of the requirements when such ships will be taken permanently out of service within two years after the implementation date specified above. Simplified Voyage Data Recorder (S-VDR), as defined by the requirements of IMO Performance Standard MSC.163(78), is a lower cost simplified version VDR for existing ships with only basic ship's data recorded.
Annual Performance Check and Certification Regulation 18.8 of SOLAS Chapter V requires that: The voyage data recorder (VDR) system, including all sensors, shall be subjected to an annual performance test. The test shall be conducted by an approved testing or servicing facility to verify the accuracy, duration and recoverability of the recorded data. In addition, tests and inspections shall be conducted to determine the serviceability of all protective enclosures and devices fitted to aid location. A copy of a the certificate of compliance issued by the testing facility, stating the date of compliance and the applicable performance standards, shall be retained on board the ship. Onboard inspection of equipment is conducted to ensure batteries, enclosures and location aids are in good condition and operational. This should be undertaken in accordance with the manufacturer's instructions by suitably qualified / experienced personnel. Successful completion of the maintenance routine should be recorded in the ship’s onboard planned maintenance system.
Training At the time of the VDR Annual Performance Check and Certification the Master must request the attending technician to instruct all deck officers in the use of the VDR and the procedures for the recovery and preservation of the data in case of an accident.

Guidelines on VDR Ownership and Recovery Ownership of VDR information The ship owner will, in all circumstances and at all times, own the VDR and its information. However, in the event of an accident the following guidelines would apply. The owner of the ship should make available and maintain all decoding instructions necessary to recover the recorded information. Recovery of VDR and relevant information Recovery of the VDR is conditional on the accessibility of the VDR or the information contained therein. Recovery of the VDR information should be undertaken as soon as possible after an accident to best preserve the relevant evidence for use by both the investigator and the ship owner. As an incident investigator is very unlikely to be in a position to instigate this action soon enough after the accident, the master must do all possible to ensure the timely preservation of this evidence. In the case of abandonment of a vessel during an emergency, masters should, where time and other responsibilities permit, take the necessary steps to preserve the VDR information. VDR input from Radar All vessels to check and display near the radar the equipment which is giving the feed to the VDR. Further to the requirements of OMD Document No. 010 ( 10.2- Radar and Automatic Radar Plotting Aids (ARPA)) governing the use of the Radar, please post a notice on the radar with VDR output stating that “TO BE KEPT ON IN ALL CONGESTED WATERS INCLUDING CONGESTED ANCHORAGES, AND IN ALL COASTAL WATERS” The Company’s OPS document 003 – Bridge watch gives details of the area which are considered as High Traffic areas which can be used as basis for the master to decide the areas he considers as congested anchorages.

BNWAS monitors the watch officer’s presence through watch safety system functions. A watch officer is required to press the button on a Timer Reset Panel or to operate navigation equipment (e.g. ECDIS, Radar, etc.) at certain intervals. When the officer fails to press the button within pre-set intervals, visual and audible alarms will be generated in the wheelhouse. If the officer doesn’t respond to the alarm, the system transfers the alarm to the Cabin Panels installed in other sections of the vessel in order to inform backup officers of the watch officer’s incapacity.
Operational Requirement As required by SOLAS Chapter V Regulation 19, the bridge navigational watch alarm system shall be in operation whenever the vessel is underway at sea. st
BNWAS installed prior to 01 July 2011 may subsequently be exempted from full compliance with the standards as laid out in MSC 128(75), at the discretion of the flag state BNWAS should incorporate the following 3 operational modes: • • •

Familiarization with the Equipment All watch keeping Officers must familiarize themselves with the setting and features of the equipment. Reference must be made to manufacturer’s guidelines for operational and maintenance requirements of the system The BNWAS will incorporate the following operational modes: • •
•
Automatic: Automatically brought into operation whenever the ship’s heading or track control system is activated and inhibited when this system is not activated. Manual ON: In this mode, the System will be activated continuously irrespectively of the Auto Pilot or Track control activated or not activated. In this Mode, Master will require to put in to operation BNWAS when ship is at sea and on Auto Pilot by using the key or password as provided. Similarly, Master will be required to use the key or password as provided for inhibiting when vessel is Manoeuvring and is on manual steering. Manual OFF: This will inhibit the System completely and there will not be any monitoring or Alarm. This should Never be selected unless the system is faulty or under maintenance.
Alarm Criteria Once the System is made active or has been reset, it remains dormant for a period of 3 - 12 minutes time delay. At the end of this dormant period, Alarms are initiated in following sequence: • • • •
It initiates a visual indication on the bridge. If not reset, the BNWAS will additionally sound a first stage audible alarm on the bridge 15 seconds after the visual indication is initiated. If not reset, the BNWAS will additionally sound a second stage remote audible alarm in the back-up officer’s and/or Master’s location 15 seconds after the first stage audible alarm is initiated. If not reset, the BNWAS will additionally sound a third stage remote audible alarm at the locations of further crew members capable of taking corrective actions 90 seconds after the second stage remote audible alarm is initiated.
It is recommended that the Equipment Specific Alarm criteria should be displayed on the Bridge at prominent location close to the BNWAS console for clear understanding of the OOW. Note: Only Master has the authority to change the Alarm timings as deemed necessary. The Setting Key or Password of the BNWAS is to be clearly handed over during Change of Command and recorded in Master’s Handover Checklist (TSM Form 077).

If within port limits, obtain the latest sounding information, including the nature of the bottom, directly from the local authorities or terminal well before arrival. Should this not be available, the master should request guidance from Thome Ship Management. If alongside, vacate the berth if any doubt about the risk of grounding.
11.2
SHIP'S DRAFT AND MANOEUVRING INFORMATION
The Master should ensure that the draft of the ship is readily available to the Officer of the Watch throughout the voyage. The draft should be displayed in the wheelhouse and adjusted as necessary to take account of changes which occur as the voyage progresses. A nominated officer must ensure that changes in draft due to ballasting (particularly at sea) are calculated and properly recorded.
11.3
•
A wheelhouse Turning Circle Diagram containing the general ship's particulars and detailed information describing the manoeuvring characteristics of the ship will be permanently posted on the bridge for ready reference. The operational status of propulsion machinery and navigational equipment should be noted next to or on this poster.
•
It should be borne in mind that the ship's manoeuvrability information will not necessarily indicate the performance of the ship at any one time as this performance will vary according to the environmental, hull and loading conditions experienced.
BOW CUSHION / BANK SUCTION EFFECT
When a ship is transiting close to land and has deep water on the other side, there is a tendency, due to the vessel’s form, for the bow to turn away or the stern to be pulled towards the land. This is called a Bow cushion or a Bank suction effect and could cause a vessel to violently sheer away from the course she is following.
11.4
SMELLING THE GROUND
This happens when a vessel in transit passes by a shallow bank on any side. The resultant effect is for the bow to swing towards the shallow area. This is known as Smelling the Ground.
11.5
SQUAT
All officers are to be aware of the effect of “SQUAT” particularly in shallow waters. Specifically they must recognise that the vessels draft will increase and trim will change with a subsequent alteration in manoeuvring characteristics. The main Shallow water effects that affect a transiting ship are: •
CONTROLLED
A ship transiting through shallow waters experiences an increase of draft and this effect is known as ‘Squatting’. Vessels start to ‘Squat’ when the depth of the water decreases to approximately two and a half times the maximum draft. When the squat effect takes place, then: o
the ships speed decreases
o
Propeller ‘paddle wheel’ effect is accentuated due to cavitation of the propeller
o
Rudder effect is reduced due to cavitation of the propeller Revision: 01 Aug 2013 Approved by DPA/DMR Page 3 of 5

o
Increases Bow cushion or Bank suction and Smelling the ground effects
o
Increases ship interaction effects
o
Increases vibration effects onboard the ship
Squat effect depends upon the block co-efficient of the vessel and is directly proportional to the square of its speed. Other factors governing Squat are: o
The relation between the ship’s draft and the water depth
o
The ratio between the ships midship underwater section and the channel cross-section.
•
Vessel’s having a block coefficient (Cb) of less than 0.70 are know as fine formed vessels and have a tendency to trim by the stern.
•
Vessel’s having a block coefficient (Cb) of more than 0.70 are known as full formed vessels and have a tendency to trim by the head. o
A rough mathematical guide for squat calculation can be used as follows:
In Open Waters: SQUAT (mtrs)
=
Cb (mtrs) 100
X
v2(kts)
X
v2(kts)
In Confined Waters: SQUAT (mtrs)
=
2 X Cb (mtrs) 100
Squat calculations must allow expected maximum speed and vessel-specific block co-efficient. When depth of water is less than 2.5 times the vessel’s draft, consider it to be “confined” waters and compute Squat calculation accordingly. As can be seen from the above formulae and the following tables Shallow water and Squat effects are largely dependent on the ships speed. To minimise these effects, the ship’s speed should be low. Thome has clear guidelines on under keel clearance requirements and Masters should strictly adhere to the same. A table of Squat Values should be drawn up and posted on the Bridge.

BALLAST OPERATIONS Purpose To outline recommendations and requirements for ballasting a vessel
Application All vessels
Responsibility Masters
12.1
BALLAST QUANTITY
Efficient ballasting can reduce stress and corrosion, and improve the vessel’s performance. This can add up to 1/2 knot on the vessel's speed. Ballasting quantities and patterns are directly controlled by the ship and is one of the most important ways a Master can control the vessel’s propulsion efficiency. •
Minimum quantities of ballast are to be taken. Sufficient ballast must be taken on to submerge the propeller, maintain the vessel's manoeuvrability, avoid excessive vibration, operate within stress limitations, and retain sufficient bow immersion to avoid undue slamming.
•
Before taking on heavy weather ballast, the vessel's speed should first be reduced. Only when sea conditions are such that a speed reduction alone is not sufficient to reduce pounding, heavy weather ballast should be taken on.
•
Speed reduction: o
Improves vessel motion
o
Saves propulsion fuel
o
Eliminates the need to burn extra fuel for ballasting and deballasting operation
The amount of ballast required to enable the vessel to ride sea conditions smoothly will vary with weather conditions. Therefore, the following is recommended.
Fair Weather For wind force up to force 4 minimum ballast is to be taken. This may be in the region of 30% DWT.
Moderate Weather With wind force 4-6 additional ballast will need to be taken and ballast may be increased to 37% DWT.
Heavy Weather With wind force 6 and above, additional ballast of up to 42% DWT will need to be taken.

OPS Document No. 012 Ballast Operations
Ducted Propellers Ships fitted with ducted propellers require deeper aft drafts than light ballast if maximum power is to be used without excessive vibrations. This draft can be established by experience and recorded on board.
12.2
DISTRIBUTION OF BALLAST
Ballast is to be evenly distributed to minimise stress. To minimise corrosion clean ballast is to be stowed in tanks with cathodic protection. If this is not fitted, the ballast pattern is to be varied to prevent uneven corrosion in isolated areas of the vessel. Tanks, whenever possible are to be either empty or fully pressed up; slack tanks are to be avoided. A good stern trim will give good propulsion efficiency. Stern trim is not to be excessive so as to hinder the operations of pumps in the engine room, or interfere with the readings of boiler water level gauges in the engine room, or cause the bow to pound. Optimum trim can be found by experience. To ensure that the maximum time is spent on ballast passage at optimum draft and trim, tank cleaning and changing ballast is to be completed as soon as practicable after discharge. It is desirable to keep ballasting at discharge terminals to a minimum. The two main advantages are: •
Reduction of berth occupancy costs.
•
Reduction of ballast pumping time; therefore saving fuel.
The primary required departure condition is to have the propeller immersed. Vessels trading to the Mississippi and other U.S. Gulf ports may be limited by air draft. Trimming the vessel by the stern reduces the mean significantly. After departure, ballast may be adjusted to suit the prevailing weather conditions etc.

POLLUTION PREVENTION REQUIREMENTS - BALLAST
Ballasting is considered by the company to be a critical operation where:•
There is a high risk of transporting water containing living organisms that may constitute a natural disaster if released in a coastal area other than where the organisms were found.
•
Oil may be introduced onto the sea via deballast operations
The special care procedures required for pollution prevention when carrying out ballasting operations is highlighted below: •
Masters are reminded that proper stability considerations must be in place before any mid-ocean ballast exchange takes place. The complexity of exchange sequences on certain vessels pose very real safety concerns as human error and equipment failure could potentially endanger the vessel.
This part of the procedure applies to the overboard discharge of ballast water or contaminated water from tanks, holds and spaces in the cargo area. For overboard discharge of engine room bilge water or tank ship slops refer to the current MARPOL requirements for the type of vessel. The requirements of the IMO Ballast Handling Guidelines, MARPOL and the companies Ballast Management and EMS Manual are to be complied with. This will include the proper operation and use of any oily water separators or detection units and overboard ballast decontamination or sediment removal devices (if fitted). Additionally port state, local authority, national regulations and, or terminal directions are to be complied with. The company requires that: Ballast handling is to comply with instructions in the vessels operational manuals, MARPOL P&A manuals and the companies Ballast Management Manual. Stresses and Bending Moments when ballast handling must always remain within limits. Trims and lists should not become extreme or dangerous. Ballast must be checked or inspected to stop or reduce the potential for oil pollution into the sea by ballast water and the following guidelines emphasised: •
Prior to arrival in port ballast pipes and dedicated ballast sea-chests are to be flushed through to ensure no discoloured water will be sighted on start up of deballast operations.
•
Prior to any deballasting:

o
A visual inspection of the ballast water is to be carried out to ensure there is no oil on top. This may be done visually, electronically (UTI, MMC, etc.) or by other methods (sampling the surface with clean white rags, etc.).
o
A notice to this effect is to be permanently marked at the ballast pump controls.
o
Sampling via tank sounding pipes may not be a proper indicator of oil contamination where the sounding pipe is solid.
o
Where manhole covers or tank vents heads are removed then these must be properly re-secured after inspection.
o
Where inspection is by overflowing to confirm no oil on top then ensure the tanks are not over pressurised.
o
A stock of oil finding paste is to be carried onboard.
o
A check of tanks adjacent to ballast tanks to be made to ensure no transfer has occurred.
•
On commencement, during and on completion (stripping of tanks) of deballasting the area around the vessel is to be checked for signs of oil.
•
All those involved in the ballasting process be aware of procedures and ensure the Chief Officer’s instructions are followed properly.
To Note: The vessel must at no stage be placed in danger to accomplish the requirements for ballast control. This includes stress and bending moment limits, the placing of chemicals (e.g. calcium hypochlorite) that may damage the vessel or toxic or dangerous chemicals that may injure the crew. Where the Master is encountering difficulty complying with local or international rules the company is to be consulted for assistance. It is company policy not to discharge oil or contaminated water other than what is permitted by current law (MARPOL). Furthermore where water from oil tanker cargo spaces is discharged it must be through an ODME device. If any oil pollution is suspected then all operations are to cease and the vessels oil pollution emergency action plan is to be activated.
12.5
MARINE INFESTATION - BALLASTING
The company advises Masters and those in charge of ballasting operations that if ballast replacement procedures are not properly followed then the risk of infestation to another environment is greatly increased and the company stresses that this is not acceptable. Several countries in the world have experienced problems with marine organisms being transferred in ships ballast water that has resulted in harm to local marine life (e.g. affecting fisheries, etc.) In an effort to control infestation, some countries are implementing governmental control of ballast water discharges within their jurisdiction by introducing regulation to allow quarantine officials to sample ballast water for analysis. Where infestation is found in ballast water heavy penalties for ships or restrictions on ballast discharge may be imposed. Master are guided to refer to the Ballast Water Management Plan, and follow the guidelines for the Ballast exchange as required by the Port of call. Class approved ballast water management plans are provided on each vessel, with different port requirements of ballast-exchange as well as reporting requirements.

Where Masters are not familiar with ballast requirements in the next port then the company, port agents or charterers are to be consulted for relevant port information and regulations. The Kuwait Convention established the Regional Organisation for the Protection of the Marine Environment (ROPME), which comprises the states of Bahrain, Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. These states have agreed to implement ballast water legislation, which are in force since 1 November 2009. For further guidance please refer to Circular 10 -2009 and MEPC 59 / INF.3. The Ballast water management plans / documentation are reviewed on random basis by the office especially during the Shipboard attendances.
12.6
OIL POLLUTION - CBT BALLASTING - TANKERS
A notice is to be placed near any sea-chest leading to a cargo pump advising of the dangers of pollution and that the sea-chest may only be opened: •
On the orders of the Master or Chief Officer, and
•
After the pump has started. ‘Start Pump before Opening Sea Suction’.
Upon commencement of ballasting oil cargo tanks there is a high potential for pollution into the sea where oil remaining in cargo pipes may back-flow through the sea chest(s) prior to the pump taking or gaining suction from the sea. To prevent this:•
Drain all deck and pumproom cargo pipelines into aft most tanks to remove static head of oil prior to pump start-up.
•
Ensure the ballasting system is properly lined up with the sea-chest valves remaining shut.
•
Start the cargo pump and ensure it is operating before opening sea-chest valves (e.g. an increase in vacuum on the suction side of the pump will indicate the pump is operational after which the sea-chest may be opened).
When starting CBT ballasting operations a good watch is to be maintained overboard for signs of oil pollution.
12.7
OIL POLLUTION – SEA CHEST VALVES – TANKERS
There is a high potential for pollution from a leaking sea-chest valve therefore the following precautions are to be taken:Reference the ICS/OCIMF Manuals:•
Prevention Of Oil Spillages Through Cargo Pump room Sea Valves
•

12.8
ATMOSPHERIC CHECKS OF BALLAST TANKS AND VOIDS
Required Testing Procedures Routine Testing of ballast tanks and void spaces is to be incorporated into the Tank Vessel loading plans. As far as practicable, testing is to be carried out using multiple sampling points. Manholes and tank access covers are to be removed to help in sampling of otherwise inaccessible areas if gas is detected at the sampling points. Atmosphere tests are to be carried out as soon as possible, on departing from the load port and thereafter on a daily basis, weather permitting.
12.9
SPECIAL BALLAST OPERATIONS
When carrying solidifying or high viscosity, or heated cargoes temperature control is critical to ensure quality and avoid discharge problems, therefore, Masters, Chief Officers and Duty Officers shall ensure that the Charterers instructions in this respect are strictly adhered to. Ballasting operations during discharge operations and similarly, de-ballasting operations during loading have to be carefully planned. Vessels are required to draw out a risk assessment of the hazards, which in this case may be primarily the effect of ‘temperature of Sea water’ on ‘the temperature on the cargo’. The precautions would include but not be limited to 1. During Loading / De- ballasting operations - The Cargo plan should be made in such manner that the Ballast tank adjacent to the Cargo tank to be loaded is empty prior the cargo is loaded. 2. During Discharging / Ballasting operations – The Cargo plan should be made in such manner that the Ballast tank adjacent to the Cargo tank to be discharged is maintained empty till the cargo is completely discharged from the tank. 3. Any lines which are passing through the ballast tanks should be efficiently drained / striped after the operation to avoid the solidification in the lines. 4. Similarly, the wells (in double hull/ bottom Ships) should be completely drained / stripped prior loading operations & after discharge operations. So that the effect of the temperature of the Ballast is not transmitted to the Cargo. 5. Temperature of the Cargo and the vapor space should be monitored regularly to confirm that the Vessel is always maintaining the temperature limitations. 6. All personnel onboard involved in the scheduled loading / discharging operations should be fully briefed on the intended cargo plan. If any variation in the agreed plan occurs such as tank rejections, cargo stowage / quantity changes, the plan is required to be immediately revised and agreed upon. Any such Special ballast operations would require a risk assessment process to identify the hazards, associated risks & evaluation followed by risk elimination measures. The Ballast plan should include the risk assessment as documented.

VESSEL MOORINGS Purpose To specify requirements for the safe and efficient mooring of vessels and maintenance of ropes
Application All vessels
Responsibility Master Navigating Officers Watch-keepers
13.1
GENERAL
When alongside the berth, sufficient mooring lines shall be sent out to ensure that the vessel remains securely moored at all times. •
Masters shall use additional moorings whenever it is considered necessary to keep the vessel safely moored at the berth (e.g. strong tidal current, very adverse environmental conditions etc.).
Deck OOW is responsible for ensuring that moorings are properly secured to meet anticipated or changing weather, tidal and freeboard conditions. Moorings shall be effectively tended during the entire vessel's stay at the berth.
Safe Handling of Moorings All Officers and Crew must clearly understand that the following hazards to personnel (Ship and Shore Personnel) can be controlled by their actions alone: •
Manual handling risks due sending ashore two or more heavy lines together
•
Use of weighted monkey’s fists
•
Inadequate assessment of tidal situation and effect of bow thruster, tug and propeller wash when sending lines away
•
Failure to have anchors home and housed
•
Failure to recognize risk of line boat getting trapped between ship and quay, particularly with onshore wind or tide
•
Ropes being paid out from winch drums getting trapped and heaved back in, instead of paying out.
•
Lowering too much line too quickly into the water
•
Sending heavy lines or wires as first lines ashore, often with vessel still moving alongside the berth

Not watching what’s happening on the jetty, due to having an adequate number of personnel on bow/stern, making assumptions and failing to warn
•
Failure to appreciate the risk to shore personnel working within the snap-back zones on the jetty
•
Tensioning or heaving–in ropes on quick-release hooks, and on small dolphins, without waiting for instructions that shore crew are clear
•
Heaving in lines at high speed without warning the shore crew, or while they are still in an unsafe position
•
Not allowing shore crew enough time to get a jammed rope off the bollard before starting to heave it in
•
Failure to give due regard to difficulties in both taking and letting go wire ropes with fibre tails and Mandel shackles
•
Failure to consider safety of both ship and shore mooring crew safety when: o
Unberthing as the number of lines is reduced and risk of failure increases on remaining lines
o
Springing a ship off the berth
The basic cause of many of these substandard actions is stress or improper motivation on the part of master, pilot or both, resulting in rushed and hurried operations. The consequences are injuries and accidents to both ship and shore mooring crews. The way to stop it happening is to take a little bit more time to get it right. A formal risk assessment followed by a proper briefing before mooring teams proceed to stations should be conducted prior to every mooring and unmooring operation.

EFFECTIVE MOORING CONSIDERATIONS
When mooring a vessel safely alongside a berth, the following should be considered: Mooring lines should be symmetrically arranged about vessel's longitudinal centre of gravity (LCG) to ensure an optimum load distribution. Breast lines are most effective when perpendicular to vessel’s centreline. Spring lines are most effective when they run fore and aft. The longer the lead given to these ropes or wires, the less need for tending as the draught / tide changes. It should be remembered, the smaller the vertical angle of line, the greater resistance to a horizontally applied load. Mixed moorings are not acceptable because ropes, in such a situation, provide minimal restraint. Lines used for the same function should be of equal diameter and length. Elasticity is: •
Proportional to length (the shorter line will assume a larger proportion of load).
•
Inversely proportional to diameter (the largest line will assume a larger proportion of load).
Vessels above 46 kDWT The vessel should be secured alongside with suitable ropes or wires to hold the vessel in place in all conditions. The following table lists the minimum mooring requirements by vessel size (OCIMF Effective Mooring). Vessels above 46 kDWT must have moorings at least equivalent to those specified in the table below. Where a minimum of 8 mooring lines are required they must be disposed as breast and spring lines equally distributed fore and aft.

All mooring lines for vessels over 46 kDWT required by the above table must be fitted on self stowing mooring winch drums (split type is strongly preferred) and fitted with brakes having a holding capacity in accordance with the table. It is strongly preferred that any additional synthetic mooring lines be fitted on similar drums.
Vessels less than 46 kDWT Vessels below 46 kDWT must provide an efficient mooring system with sufficient retention capability to securely maintain position while at the terminal. The following table can be used as a guide for the smaller vessels calling at terminals. Masters must recognise the need for vessels to supply a safe and efficient mooring arrangement.

MOORING LINES
Mooring lines shall be ordered and acquired via the Company Purchasing Department and conform to required standards. Mooring wires should be supplied with the construction of 6x37 with IWRC, galvanized, 220 metres long. Diameter depends on ship-size. If the specifications are different from this standard (construction, cores, diameter and length), the supply should be discussed, reviewed, and approved by the Marine and the Technical Departments. The MBL of the mooring wire of 42 mm diameter should not be greater than 120 tons. Mooring ropes should preferably be of Polyester / Polypropylene blend material with a construction of 8 strands, 220 metres long. If the specifications are different from this standard, the supply should be discussed, reviewed, and approved by the Marine and Technical Departments. Vessels may be supplied initially with different types of ropes, the Master must assess using the above tables if he has adequate holding power for his vessel. Mooring ropes, wires and mooring tails should be ‘tagged’ for positive identification with their corresponding certificate. Suggested means of ‘tagging’ is by stitching a 6 to 8 inch wide stencilled canvas piece close to the eye splice. Each certificate should bear the number stencilled on the corresponding rope / wire / tail. A number of newer synthetic material for ropes, such as Aramid fibres (Kevlar) offers high strength, low weight, low stretch, and flexibility and corrosion resistance. The main benefits of Aramid fibres are reduction of diameter and therefore weight of line required. This reduction is advantageous if winch drum size is limited whereas the reduction in weight makes handling substantially easier. The disadvantage of Aramid ropes are with regards to Bend radius and there is a need to sheath the fibres to guard against ultraviolet rays and mechanical wear. Damage to this outer sheath can result in rapid degradation of the core fibres CONTROLLED

HMPE – High modules polyethylene is a fibre form of high density polyethylene. Amsteel Blue which is lighter than water thus it has a higher specific strength than Aramid. It has a relative low melt point. These lines which are urethane coated have a good resistance to ultraviolet degradation over time have excellent resistance to Ultra-violet light. It has tendency to creep and can rupture due to that property at sustained high loads. These fibres do not exhibit axial compression fatigue problems; it has a low coefficient of frictions and has very good abrasion resistance. Amsteel blue is also flexible, easy to handle and it floats. Spectra fibre is one of the world’s strongest and lightest fibres. A bright white polyethylene, it is ten times stronger than steel, more durable than polyester and has a specific strength that is 40 percent greater than aramid fibre. Spectra fibre is made from ultra-high molecular weight polyethylene. Light enough to float; it also exhibits high resistance to chemicals, water, and ultraviolet light. It has excellent vibration damping, flex fatigue and internal fibre-friction characteristics, and Spectra fibre’s low dielectric constant makes it virtually transparent to radar. Spectra fibre is hydrophobic; it will not absorb moisture or deteriorate in water. Spectra fibre can be an ideal substitute for wire and steel in mooring lines for tankers, Complementing Spectra® fibre’s high strength is its extremely low elongation of just three percent. A rope with low-stretch properties provides greater sensitivity, allowing crew members to know what is happening on the other end of the line. Hawsers made with Spectra® fibres weigh only 2.75 lbs. per foot and have a diameter of only 3.5 inches. Therefore fewer crew are needed to handle the line, and it is easier for them to perform critical tasks without jeopardizing their health and safety. Mooring tails shall be of combined fibre or Nylon and are not to be more than 11 Metres long and have a MBL of 125% (137% in the case of Nylon) in excess of the Wire rope in use. Tails should be replaced 18 months after being put into service unless inspection indicates a longer or shorter period is warranted. All Mooring wires shall have mechanically spliced eyes. Any manually spliced wires should be considered temporary and be replaced at the earliest opportunity. Existing mooring ropes / wires and rope tails onboard are to be changed out with replacements of the specification as indicated in the above paragraphs when condition and / or age of service warrants. A mooring wire is to be connected to the mooring tail by means of a shackle (Mandal – has a curved roller and the wire should be connected to it or Tonsberg – has a straight pin and the tail should be connected to it). In addition, the tail should be served with leather or plastic sheathing. Only one type of connecting shackle is permitted on board a vessel. All mooring ropes, wires, mooring tails and mooring shackles on board must have a test certificate. The certificates should identify the location of the mooring rope, wire, mooring tails and joining shackles which are in use. Mooring wires should be end for ended every five (5) years and replaced every ten (10) years, unless deterioration of the wire dictates an earlier period of replacement. Details of mooring arrangements and certificates shall be filed in the Mooring Equipment Record Folder.

SPARE MOORING WIRES AND ROPES
Vessels are required to have adequate spare mooring wires and ropes. The following may be used as a guideline
13.6
•
Two (2) spare mooring wires or ropes (as applicable)
•
Four (4) spare mooring tails (if applicable)
•
Two (2) spare mooring ropes (which are used as tug ropes)
CARE OF WIRES AND ROPES
It is essential that wires and ropes be regularly inspected and maintained. Wires and ropes should be routinely inspected every 3 months by the Chief Officer. Records of inspection should be maintained on board, stating the date of inspection, the rope or wire inspected, and a short statement about its condition. Additionally, prior to and after every use, the ropes / wires should be checked for excessive wear or damage. Damaged ropes or wires should be replaced immediately. All mooring ropes and wires must be replaced at least every 10 years, unless experience and /or inspection indicate a longer or shorter period is warranted. For mooring wires and fire wires, a fine coating of water proof grease (type: Ferryl 202) should be applied at frequent intervals. This greatly promotes the life of the wire and reduces corrosion. It is essential that the wire should not be over greased as this could increase the risk of water pollution (rainbow effect) when contacting water.

Ropes should be checked for excessive abrasion and wear. Frayed ropes should be replaced. Ropes should be stowed on gratings or pallets so that airflow can pass under the ropes. Ropes should be stowed away from heat sources, chemicals and paint. For additional care of wires avoid the following: •
Leading wires around sharp edges
•
Crossing the wire on the drum
•
Kinking the wire
•
Leading wires through excessive angles
Care and maintenance of Aramid mooring ropes (Kevlar) Protect the fibres against ultraviolet rays and mechanical wear. Protect against damage to the outer sheath which could result in rapid degradation
Care and maintenance of HMPE mooring ropes (Amsteel Blue, Spectra) Amsteel Blue mooring ropes do not require lubrication because it does not rust. Its flexibility and extreme light weight will allow for an easier, faster and safer mooring sequence. When using these lines ensure the chocks and lead maintenance should be instituted to eliminate rough wearing surface, metal burrs and sharp cutting edges (localized grinding and surface preparation). To ensure best performance of the lines maintain bending radius recommendations and that all bending surfaces are smooth and free of abrasive and/or cutting edges. Inspect the winch drums for rust, corrosion or scoring damage. These areas should be cleaned up so as not to cut and abrade these ropes. The maintenance of deck winches is important in the long term service life and performance of the rope. These lines are excellent resistance to ultra-violet light as they are urethane coated. Avoid metal friction for extended period of time and recommended to use of chafing gear in chocks between the metal and the rope. Inspect the line each time they are deployed or re-reeled. If you find melted or cut fibre further inspection is warranted.
Care and Maintenance of Nylon Rope Tails Tails should be replaced at least every 18 months, unless experience and/or inspection indicate a longer or shorter period is warranted. A longer period is acceptable (more than 18 months), provided there is a proper mooring inspection log onboard. Each vessel must have a proper mooring log established. The mooring log should have following content. •
One page for each winch
•
Copies of mooring wire and tail certificates
•
Date when both mooring wire and tail are first time taken into use
•
If tails are disconnected for a period this must be noted into the log, also where stored
•
Date when tails are checked and maintenance carried out
•
The more frequent used, the more frequent inspection

Inspection and Replacement Some signs of damage such as hockling, cuts, surface abrasion and fusion are readily visible. While it may not be possible to prescribe definitive retirement criteria, Mooring equipment guidelines Sec 6.3.5 / page 105 – Inspection and replacement provides general guidelines which master are requested to review during each inspection. Refer to OCIMF- Mooring equipment guideline – Appendix B and Appendix C
13.7
FIRE WIRES
Fire wires should be 28mm x 45m for 20-100 kDWT and 38mm x 60m for 100-300 kDWT vessels, as recommended by OCIMF. th
Fire wires should be rigged as per OCIMF-Mooring Equipment guidelines (ref 3.11) and ISGOTT 5 Edition, Chapter 26.4 (4) and Chapter 26.5.5 guidelines unless the terminal requests a different th method of rigging. If a deviation from OCIMF & ISGOTT 5 Edition guidelines is requested by the terminal, an entry should be made to this effect in the Port / Deck log book and on the Ship Shore Safety Checklist.
13.8
MESSENGER LINES
Messenger lines for VLCC should be of braided polyester or plaited polyester or polyester / propylene mix, 40 mm diameter, 200 m length, with 1.8 m eye splice at each end and one shackle per messenger line. Four such messenger lines are required as per Exxon Mobil’s Marine Safety Criteria for STS operations, and vessels must ensure compliance accordingly.
13.9
WINCH BRAKE EFFICIENCY AND TESTING
Ropes and wires shall be correctly reeled on to a winch, in order to ensure correct load application. (Ref OCIMF – Effective Mooring Fig 12 – The brake band is designed to pull directly against the fixed end of the brake band) Reeling the line incorrectly may reduce the brake holding power by up to 50%. Brake rendering capacity is to be tested annually or after the vessel has experienced excessive strain on the mooring equipment. Test results are to be indicated on the winch brake holding certificate. Brake rendering should not be more than 60% of the mooring Ropes / Wires Minimum Breaking Load (MBL). It should be remembered that multiple layers of wire or rope on the working or heaving drum, reduces rendering capacity. For example: having three complete layers on your winch drum can reduce the brake holding capacity by 11%, 5 layers can reduce the brake capacity by 31%. It should be remembered that in extremes of weather, vessels which are not fitted with split drums, may suffer more readily from uncontrolled paying out of lines. The brake rendering capacity and the test date shall be stencilled on all the mooring drums. Brake Testing should be undertaken as follows: •
CONTROLLED
The way that brakes are tested is described in OCIMF Mooring Guidelines under section 7.5. It is recommended that this be followed in all cases where testing is to be performed

OMD Document No. 013 Vessel Moorings
•
There is often a miss conception concerning Brake holding and Brake rendering point. It should be remembered that it is necessary to choose the optimum rendering point of the winch as per the MBL of the mooring line that is to be used with the winch
•
In view of this, the following additional procedure should be adhered to: o
After rigging the BHC test equipment, the brakes on the winches should be tightened as much as possible. The hydraulic Jack should be pumped to the desired rendering point
o
The brake should be released slowly until the brake begins to slip. A marking mechanism which can easily be overridden, in case of emergency, should then be attached to the threads of the brake device so that the brake spindle can be tightened up to this reference mark
Use of Brake Slacking a mooring line on brakes is dangerous and should not be attempted. If a line has to be slacked down, this shall be conducted with the winch in gear.
Winch in Gear Leaving a winch in gear, with power on and set to heave, should only be considered in emergency situations and shall never be carried out as routine operation.
Freezing Weather Precautions Chief Engineer is responsible for ensuring that steam operated winches are protected against the consequences of freezing, when in operation. This can be accomplished by: •
Ensuring that deck lines and steam chests are thoroughly drained, with drain valves left in open position
•
Winches are continuously operated at slow speed
•
Deck OOW is responsible for ensuring that program is carried out in accordance with Chief Engineer's instructions

14.1
STEVEDORE DAMAGES TO VESSEL
The Stevedore Damage clause(s) of the Charter Party may vary from one Charter party to another; however, it is a standard requirement in all clauses that a written notice of the damage be issued immediately any damage by Stevedores comes to your attention. This stevedore damage report should include the following: •
Port and date of the occurrence
•
Time of the occurrence
•
Where the damage occurred noting the affected part of the vessel
•
Details of the damage (extent of damage)
•
Cause of damage, reasons for damage
•
Who did the damage (name of Stevedore, winch or crane operator etc.)
•
Witnesses at the time (Chief Officer, 2nd Officer, Supercargo, stevedore’s foreman etc.)
•
To whom was the damage reported at the time
•
Signature of Stevedores' foreman or other responsible person
•
Any other necessary remarks
•
Photographs, if any taken, of parts involved.
Many times the stevedores who are responsible for the damages refuse to sign the Stevedore Damage Report accepting liability and in such cases, you should make every effort to obtain their signature with the remarks "acknowledge receipt only" or "for receipt only". If, however, it is impossible to obtain any signatures from the stevedores concerned, you should state underneath "Stevedores refused to sign", and you should make every effort to place them on notice by telex or registered letter. The Stevedore Damage Report should be addressed to the Stevedores who caused the damage and copies should be sent to the following:

•
Agents at the port where damage occurred and local P & I Representatives.
•
TSM office
•
Supercargo on board (if any)
•
A copy must be retained on board in the relevant voyage file.
It is always advisable and preferable for all such damages to be repaired on the spot by the Stevedores concerned. Time and facilities available should be taken into consideration. However, irrespective of whether the Stevedores promise to repair the damages after completion of loading or discharging or during discharging, you MUST ALWAYS, issue the written Stevedore Damage Report immediately when the damage occurs. In some cases, Stevedore damages are not immediately detected because the Stevedores have covered the damage with cargo. In such cases, especially when loading heavy cargoes such as steel products, machinery etc., a letter should be given to the Stevedores with copies to all parties concerned, holding them responsible for any hidden damages which may have occurred during loading, but which may only become apparent during discharging. Officers should be well briefed on this matter and they should be alert and observant in order to detect any damages when and where they occur. Damage should be reported as soon as possible. Sometimes the Stevedores may choose to repair the reported damages on completion of discharging, in which case you must ask them to give you the estimated time for such repairs and contact your Time Charterers by phone or telex, to obtain their agreement to the delay. They may wish to carry out the repairs themselves later, or reimburse your Owners with the costs involved. Should the Time Charterers instruct you to sail without having any repairs done, you should ask them to confirm this by telex/cable to you. They would have to accept responsibility for these damages. •
Any repairs may only be deferred, provided they do not affect your vessel's sea worthiness or cargo handling efficiency.
•
In every case, when you are in doubt, contact Thome by telephone, telex or cable for necessary instructions also contact your local P & I representative for his advice.

CONTAINER LOADING Purpose To clearly define the precautions and procedures for loading various types of containers
Application Container vessels
Responsibility Master
16.1
CARGO SECURING
Reference should be made to the “Cargo Securing Manual” for the particular vessel. It is common practice for shore lashing gangs to be used for securing containers, however prior to departure from a port, the ship’s crew should be used to check that all containers are secured properly. Containers stowed on deck are exposed to weather at sea. Daily checks should be made to ensure lashings are secured properly and doors on containers are intact and in good order. Upon completion of discharge, all portable lashing equipment should be checked and stowed in its proper place for subsequent use during the next loading.
16.2
HAZARDOUS CARGO
Prior to loading, when preparing the cargo plan, dangerous goods listed in the cargo listing must reflect the IMDG Code. Reference should be made to the IMDG Code and complied with and if need be, check with Thome. In preparing the bay plans, care should be taken to make sure that the containers are stowed in accordance with the IMDG Code requirements, i.e. underdeck stowage, on deck stowage etc. All dangerous goods are to be clearly marked on the loading plan and the loading plans are to be readily available for immediate use in case of an emergency. When these containers are loaded, they should be stowed strictly according to the loading plan and clearly labelled as per IMDG Code.
16.3
STABILITY
Vessel is to meet IMO stability criteria at all times. Special attention should be paid to “windage” as described in the loading manual. The ability of the vessel to withstand the combined effects of beam wind and rolling should be demonstrated for each standard condition of loading with reference to the vessel’s loading manual.
16.4
OVERSIZE/UPGRADED CONTAINERS
All oversize and upgraded containers (strengthened and capable of lifting weights over and above standard containers) should be clearly indicated on the loading plan and necessary precautions taken during loading. Stack weight for cells and underdeck clearance for upgraded/oversize containers should be taken into account when planning the cargo.

OMD Document No. 016 Container Loading
OPEN CONTAINERS
Open containers are used for promoting ventilation and are usually loaded on deck. Produce such as onions, potatoes, etc. are usually carried in these containers. To prevent spillage from the sides of these containers, nettings, webbings or planks are used and these should be checked to ensure that they are properly secured.
16.6
REFRIGERATED CONTAINERS
Upon loading refrigerated containers, temperatures should be recorded and logged. After loading, temperatures should be recorded and logged one time every watch. Where thermographs are fitted, sufficient chart paper should be carried and changed when required. Sufficient adapter plugs to fit ship’s sockets should be carried on board, for integral and clip-on units. Refrigerated container temperatures should be maintained as per shipper’s requirement as found in the cargo manifest. Reference should also be made to shipper’s special instructions.
16.7
FLAT BED CONTAINERS
Flat bed containers are mainly used for unitised cargoes such as machinery, vehicles, equipment, etc. A thorough check should be made that all unitised cargoes are properly secured and lashed to the flat bed upon loading.
16.8
CONTAINER SEALS
All container seals should be thoroughly checked, especially the ones on deck. Any seal found broken should be immediately reported to the stevedore’s foreman and or planner. The container should be sealed with a replacement seal and the plan amended accordingly to reflect the new seal number.
16.9
DAMAGED CONTAINERS
Duty officers should be vigilant while loading is in progress to detect any damaged containers. Where the structural integrity of the container is in doubt, the container should be rejected. Similarly, the container doors should be intact and of sound condition, otherwise the container should be rejected.

Securing maximum cargo intake, i.e. maximum freight, the following guidelines are applicable: o
Dirty Cargoes should be loaded in as few tanks as possible and in tanks that have a recent compatible (last 3) cargo history
o
If vessel is not fitted with SBT (segregated ballast tanks) one line should be reserved for loading clean ballast in the clean tanks, provided the pumping requirements can be met by the vessel

Loading same procedure as above and always observing the pumping requirement
Unleaded / clean petroleum products o
When loading, sensitivity considerations must be taken into account
o
In some cases these products should always be loaded in tanks having a similar cargo history of 3 previous cargoes, even if this means loading with slack tanks. Unless instructed, unleaded products should only be loaded in tanks where the last 3 cargoes were unleaded tanks. If any doubt exists regarding the suitability of tanks for a particular grade advice should be sought from Thome and/or Charterers
Vegetable / Fish oils and Molasses o
Suitability of tanks after previous cargoes should be verified to comply with FOSFA requirements and other applicable guidelines
At Loading Berth Notice of Readiness acceptance is to be endorsed by Charterers, Shippers Representative, and Terminal Representative.

Proper checks to be made of all cargo compartments to check if dry / suitable / acceptable to cargo Shippers and, or independent appointed Surveyors. “Tank Inspection Report” to be appropriately filled out and endorsed by all. Ship/Shore Safety Check-List (Form TSM 013) to be completed by both parties prior to the commencement of Operations.
Rejection of Tanks Before loading is commenced, the tanks will be inspected by a surveyor acting on behalf of the charterer. We would like to draw your attention to the fact that, in some instances, the surveyor may reject the tanks as a delaying manoeuvre because the cargo is not ready for loading. If you suspect that this may be the case, agents should be requested to engage an independent surveyor to inspect the tanks, on our behalf, and issue an Inspection Certificate. If the tanks are found to be in order, a Letter of Protest with a copy of the Inspection Certificate should be sent to Charterer's representative. After having ordered the surveyor, please endeavour to establish, possibly through a visit to the refinery and, or storage area, whether the intended cargo is actually ready for loading. Thome, Charterers and Owners must be alerted if tanks are rejected.
Cargo Segregation / Mixing / Contamination The slightest contamination of cargoes either by mixing of grades or by mixing of cargo and water will, often, ruin the entire contents of a tank resulting in heavy claims. •
It is the vessel's responsibility to avoid any kind of mixing/contamination and the utmost care should be taken to eliminate accidents.
•
Mixing orders o
Any orders or requests from charterers / shippers or time charterers for mixing, blending or adding additives/other substances to cargo are to be relayed to Thome for investigation and possible authorization before you proceed with such an operation.
o
Where the vessel receives orders to co-mingle, an LOP must be issued denying responsibility for final condition or specification of co-mingled grade.
Lining up Pipelines and Valves Prior to commencement of Loading, deck and pump room lines should be set. Where facilities allow, loading lines should be set so that cargo flows through loading drop valves and bypasses the pump room. Pump room cargo-line valves not being used for loading should be firmly shut. Sea suction valves should be lashed shut and preferably sealed by the Surveyors. Deck valves that are not going to be used should be lashed shut. The offshore manifold valves should be tightly closed and blanks should be secured firmly fully-bolted in place. Gauges are to be set to ensure offshore valves are not passing. The position of all main, stripping and tank valves must be specifically checked to ensure that those which should be closed are, in fact, closed. Requirements for double valve segregation must be given extreme care.

Line / Valve settings are to be supervised and checked by the Watch-Officer and re- confirmed by the Chief Mate. After re-confirmation, this must be recorded in the Port Log as “Cargo valve line-up checked and confirmed.” This entry must be recorded before commencing cargo operations. Safety procedures for measuring and sampling inert tanks are to be strictly adhered to. Please refer th to and follow the precautions detailed in ISGOTT 5 Edition Chapter 11
Setting of Venting System The vessel should always use closed loading. All ullage-ports are to be closed and checked prior to commencement of Loading. Purge – pipes (if installed) to be closed and checked. All cargo tank vents should be set to the loading position. PV valves to be set to ensure the high exit velocity of vented gas. Ensure that inert-gas plant is shut down, the deck isolation valve is shut and lashed, and that the main inert-gas venting valves are open. Precautions should be taken and the venting system set accordingly to ensure compatibility of vapour when loading different grades of cargoes.
Setting for Pressure Sensor and Alarm Systems If pressure sensors are provided as means of secondary protection, the alarm settings for the pressure sensors must be set to activate as per the following chart. Inerted Vessels
Non Inerted Vessels
High pressure alarm to be set at 10% greater than normal actuation settings of pressure valves
High pressure alarm to be set at 10% greater than normal actuation settings of pressure valves
Alarms at a high pressure of not more than 90 percent of the lowest pressure relief valve setting in the cargo tank venting system
Low pressure alarm at 10% greater than normal actuation settings of vacuum valves
Alarms at a low pressure of not less than four inches water gauge (0.144 psig) for an inerted tankship, or the lowest vacuum relief valve setting in the cargo tank venting system for a non-inerted tankship
Low pressure sensors should be set to alarm above zero, so that the pressure in a tank should never be permitted to fall below zero. We recommend same to be set at 100 mm WG.
Vessels equipped with Vapour Collection System
In reference to above, please note that Pressure sensors setting for inerted and non-inerted vessels refers to individual tank pressure setting as required by OCIMF. The pressure sensors setting for vessels equipped with vapour collection systems, refers to the pressure sensor in the main vapour collection line.
Start of Loading When all the Pre-Arrival, Safety, Anti-Pollution, and Venting checks are completed and satisfactory, the vessel is ready to commence Loading. CONTROLLED

The Manifold valve to be opened only after the Chief Mate receives confirmation from the Terminal as to their readiness to commence Loading. Once Loading commences, ensure that the cargo is flowing into correct tanks. The loading manifold should be inspected to see if there are any leaks from loading arm connection or from any blanks at both sides of manifold. Check over the side for any possible escape of oil through sea-valves, drain cocks and plugs. After these checks have been made, and found satisfactory, the Chief Mate shall inform the Terminal to gradually increase the loading rate to the agreed full loading rate. Flow through of the oil to individual tanks should be restricted to avoid splashing and turbulence during the initial load period to reduce any static charge accumulation.
Monitoring of Cargo tanks The ullages of the tanks being loaded should be frequently and regularly monitored, and recorded every hour, special care to be exercised when tanks are approaching the topping off range. Cargo temperature and density should be taken at the start of loading and at the end of loading. The temperature should be monitored throughout the loading. The vessels stresses in the way of Bending Moments and Sheer Forces should be monitored on an hourly basis to ensure that the vessel is always within the permissible limits of the harbour conditions. This requirement is to be included in the chief officers' written orders/cargo operations plan. Filling of tanks to a pre-determined ullage, securing the flow and transferring flow to other tanks at same time is a critical operation. Sufficient manpower must be made available to handle valves and read ullages. Extra care is to be taken to avoid over-pressurization or ship and shore lines by shutting-off too many valves against the cargo flow.
When topping-off All cargo high level and overfill alarms are to be energized during cargo operations. The maximum cargo level in a cargo tank may not at any time exceed 98% of the cargo tank volume, the level at which over-fill alarms must be set. In cases where the cargo level in the tank reaches the alarm point and the alarm must be silenced or de-energized, the duty officer must be constantly aware of the status of each alarm. When commencing discharge of tanks loaded to 98% capacity, the high-level and over-fill alarms must be activated as soon as cargo levels allow. In all instances, high level and over-fill alarms must be tested well in advance of cargo operations where the alarm status must be confirmed. Keep in mind closing-off one tank increases flow rate to other open tanks. As vessels trim by stern rate of flow to aftermost tanks will be more. Never shut-off against the flow of cargo. Always allow flow into another tank first and then shut-off flow into the tank being topped-off. The Officer in charge of topping-off tanks must give this operation his undivided attention and not perform any other duties simultaneously. Errors during topping – off operations are one of the main causes of oil spills on ships and it is essential that the Chief Officer has a detailed topping off procedure prepared. The need for an adequate number of personnel on deck can not be over emphasised. The Chief Officer should ensure sufficient personnel are available on deck to complete the operation safely.

Topping-off begins with the systematic staggering of the tanks so that they reach their full levels in a carefully controlled sequence. Whenever possible, topping-off should be completed in two-stages; wing tanks followed by centre tanks. Some vessel may not be fitted with Wing tanks so the vessel topping of configuration might change. Wing tanks fitted these should be topped off first with the centre tanks being shut off when they reach a certain desired ullage. Shutting down centre tanks when they reach the prescribed ullage should be done SLOWLY and CAREFULLY to prevent pressure surges in the loading line. Check to ensure that the centre tanks are indeed shut and the ullage is not changing. Make sure that there are sufficient wing tanks open to cargo as the centre tanks are shut down. In normal circumstances it should be possible to maintain the full loading rate during this process. However, if the Chief Officer is in doubt he should request the terminal to reduce the rate accordingly. Before topping-off operations begin, the Chief Officer should ensure that he has notified the terminal in good time. The hydraulic oil tank level should be checked and the Portable Manual Hydraulic Valve pump should be available and ready for immediate use. Before each tank is topped off, the operation of the tank valve should be verified by carefully closing/opening it. To avoid any confusion and errors in communication at this critical stage of loading, the final ullage for each tank should be clearly marked at the CCR control panel and on the deck so that the personnel involved in the topping – off know what the final ullage will be. Both portable (MMC) and remote ullaging devices should be used and compared during topping – off. Remote ullaging systems must be calibrated before topping-off begins. The Tanks should be topped off using the portable MMC and at the same time the ullages in the CCR are monitored. Vessel which are not fitted with Independent High level alarms (98%) to ensure this stage of operation is well monitored and all personnel involved are well aware. If possible the alarm system which is fitted with the Ullaging system to be reset to 98%. Allowance must be made for the height of the reference point, trim and list as well as the ullaging (vapour lock) / remote sensor positions (which are likely to be different). On completion of the topping-off of the wing tanks, the centre tanks should be opened again and staggered to finish in the desired sequence. As the wing tanks are completed and topped-off, the centre tanks should be cracked open to relieve the pressure on the lines. As more wing tanks are shut down, so more centre tanks should be opened. A smooth transition from wings to centres is required so that pressure surges and high back pressures at the Terminal's pumps are avoided. The Chief Officer should keep the Terminal informed of his actions. The exact requirements regarding notice and reducing rate will vary from terminal to terminal and this will have been discussed in the Pre-Transfer Conference. The terminal should be given plenty of time for actually reducing rate and stopping. The Chief Officer should also make an allowance in his final tank ullages for any line fills and any delay between request to stop and actual stop. Cargo tanks should never be loaded beyond 98% of tank capacity in order to maintain a safety margin during topping off and to guard against volumetric increase and possible overflow due to change of temperature on the loaded voyage.

OPERATIONAL CHECKS
Continuous draught monitoring The draughts must be continuously monitored by the remote draught gauge, in order to know if the actual figures are in accordance with the Approved Loading Plan. When alongside a berth, if possible, comparisons should be made between remote draught gauge readings, calculated draughts and visual observations of draughts on the hull.
Cargo and Ballast Calculations As soon as possible the officer on watch should compare the actual temperature and the actual specific gravity with the figures announced by the loading master. If there is any difference the chief officer has to inform the master and the loading master. Together with the ullages and above figures, the officer on watch should compute the laden quantity and compare it with the foreseen loading rate, as well as with the draughts. The Officer on Watch must monitor cargo tank ullages, ballast tank soundings and draughts throughout the loading operation. Quantities of cargo and ballast onboard and draughts must be calculated and recorded hourly. Hourly comparison with the Approved Loading Plan must be made by the officer on watch to ensure any abnormality is detected at an early stage. The officer on watch should immediately inform the chief officer of any abnormality. On completion of deballasting operations, all ballast tank soundings must be verified and comparison made with the Approved Loading Plan. The officer on watch should immediately inform the chief officer of any abnormality.
Hull stress control by the dedicated Cargo Loading Computer The proper functioning and accuracy of the Cargo Loading Computer must be verified using the test conditions which have been approved by Class. Testing should be conducted in accordance with the manufacturer’s instruction manual. Tests must be conducted at least once every four months and the test records maintained. The Cargo Loading Computer has to be used at least every hour, in order to verify if intact stability, shear forces and bending moments are maintained, and will be maintained, within the permitted limits.
Moorings The Watch Officer is responsible for frequent and careful tending of moorings. When tending moorings which have become slack or too taut, an overall view of the mooring system should be taken so that the tightening or slackening of individual moorings does not allow the vessel to move or place undue stress onto other moorings. •
CONTROLLED
The following should be considered when tending moorings: o
Significant increase in wind speed or change in wind direction, particularly if the tanker is light laden and with off shore wind
o
Swell conditions
o
Periods of maximum tidal flow
o
Low under keel clearance
o
The close passing of other ships Revision: 09 Dec 2013 Approved by DPA/DMR Page 7 of 43

•
All normal precautions taken during berthing and cargo handling operations alongside a jetty also apply with a tanker at a buoy mooring
•
While the tanker is at a multi-buoy mooring, frequent and regular inspection is essential to ensure that mooring lines are kept taut and that movement of the tanker is kept to a minimum. Excessive movement may cause rupture of the cargo connections
•
At single point moorings, a watchman should be stationed on the forecastle to report any failure or imminent failure of moorings or leakage of oil. He should also report immediately if the tanker 'rides up' to the buoy. He should be equipped with appropriate means to communicate with the Officer of the Watch
•
Except at terminals where no tugs are available, towing off wires of adequate strength and condition should be made fast to bollards on the tanker, forward and aft, and their eyes run out and maintained one metre above the water line. For tankers alongside a jetty the wires should be over the offshore side, and for tankers at a buoy mooring they should be placed on the side opposite to the hose strings
•
The towing-off wires are to be set as per terminal instruction or as per OCIMF Mooring Equipment Guideline if no specific instructions received
Manifold Frequent checks should be made of the loading arm connection and manifold. Both onshore and offshore sides of the manifold should be inspected for complete integrity. A watchman is always to be situated at the manifold.
Pump Room The pump room should be checked for integrity at least hourly. Pump room entry procedures as per SHEM 8.1 are to be observed by all persons entering the pump room.
Weather Careful watch should be kept for adverse weather conditions. During electrical storms whilst loading, the loading should be stopped and all tank openings and vent lines closed. If the vessel is at an exposed sea berth, adverse winds may mean that the cargo operation will need to be stopped. Close liaison should be kept with shore authorities.
Water around Vessel A Watch should be kept on water around vessel for oil slicks. If oil is seen around the vessel, its source should be established, i.e., whether coming from another vessel, from the jetty or from own ship. If oil is seen, an appropriate entry must be made in the port log book.
Gas Evolution When loading high vapour pressure cargoes, a watch should be kept on the wind speed and direction. When there is little air movement, a gas cloud may form on lee side of accommodation. In such conditions, the Master should liaise with the Terminal as to the requirement to stop cargo for safety reasons.
Routine Checks Ballast tanks and voids adjacent to cargo tanks must be checked on a daily basis for cargo leakage. CONTROLLED

DISCHARGING
Prior Arrival Discharge Port ETA notices prior to arrival at the discharging port are to be given according to the Charter Party, voyage instructions from charterer and, or instructions from Thome. The Chief Mate is instructed to prepare detailed cargo discharge plans specific to ship and cargo. Masters are to verify and approve the format prepared by the Chief Officer and revert with any further suggestions for a standard format for cargo related forms.
Operational Objectives The objective of every discharge is the production of the maximum quantity of cargo whilst maintaining operations of the highest safety and anti-pollution standards.
Discharging Strategy The discharge sequence is to be such that the vessel has a good draining trim at an early stage in the discharge. This will allow early effective stripping.
Limiting Factors •
Draft o
•
•
Berth Time o
Some terminals limit the berth time. In order to fully out-turn cargo, it may be preferable to minimise ballasting time by taking on reduced ballast alongside or ballasting during discharge - this is always to be carried out bearing in mind the safety of vessel.
o
The latter is only to take place when the tanks to be ballasted have been fully stripped of cargo, and the vessel has efficient two valve separation. There must be at least two valve separations on main pump room suction line between cargo and sea valves.
Stress o
•
Discharging terminals usually have limited depth of water at the berth. This may prevent the vessel gaining a good draining trim until late in the discharge.
Vessel must not exceed the maximum still water stress limits at any time during cargo operations. The Vessel’s stress in way of Bending Moments and Sheer forces to be monitored on a regular basis to ensure the above and an entry of the same to be made in the port log book.
The vessel also may have operating constraints such as: o
leaking pipelines
o
faulty valves
o
inoperative pumps
These may be overcome in the discharge operation by the careful planning of operations. These defects are to be notified to Thome and repaired as soon as possible. CONTROLLED

Pre-Transfer Safety Meeting Before discharge operations commence, the Safety meeting is to be held together with the Terminal authorities. This should cover all aspects of the cargo discharge or ballast operations during the vessels projected stay. Any special requirements from vessel or terminal are to be discussed and noted down by both parties to avoid any delay or confusion at a later stage.
Lining up pipelines and valves Prior to commencing discharge the cargo tank line and pump room valves to be set as per the plan for start of discharge. Valves not in use should be secured and lashed shut. Line / Valve settings are to be supervised and checked by the Watch-Officer and re-confirmed by the Chief Mate. After re-confirmation, this must be recorded in the Port Log as “Cargo valve line-up checked and confirmed.” This entry must be recorded before commencing cargo operations.
Ullaging / Sampling Prior to commencement the vessels tanks are to be gauged by the Receiver / Terminal / Independent Surveyors if any, and cargo quantity affirmed and endorsed for. •
Sampling of cargo is to be carried out as per the guidelines laid out in Section 17.11
•
It is important to maintain the integrity of the cargo tank atmosphere during ullaging / sampling.
Inert Gas / Venting Vessel is to fully comply with Procedures for Inert-Gas Operation as laid down in Section 18 of this Manual.
Setting for Pressure Sensor and Alarm Systems on Inerted Vessels If pressure sensors are provided as means of secondary protection, the alarm settings for the pressure sensors must be set to activate when the tank pressure or vacuum reaches 10% above the normal actuation settings of the pressure or vacuum valves themselves. In the case of the lowpressure settings, the pressure in a tank should never be permitted to fall below zero and the pressure sensors should be set to alarm above zero. We recommend same to be set at 100 mm WG.

OPERATION OF CARGO PUMPS
Starting Pumps are to be started or operated as required in the Manufacturers Instruction Manual. Preoperation checks must be carried out including confirmation that the pipeline system is properly set. When starting pump flows, pressures are to be maintained at minimum although this requirement may be revised where line clearance techniques are employed. Only on confirmation from the receiving terminal should flow/pressure be increased to max agreed.
Running at Full Nominal RPM Centrifugal pumps are to be run at their full nominal rpm during bulk discharge. Reduction of rpm leads to a rapid decrease of pumping rate and efficiency. When the tank ullage is nearing stripping CONTROLLED

level, it is preferable to partially close the discharge valve, rather than reduce pump revolutions, in order to reduce the flow rate. Rpm may then be reduced as necessary. Cavitation will occur when the pump tries to discharge more cargo than is able to enter the suction i.e. with high viscosity cargo. There is a danger of drawing gas or air instead of liquid into the pump, the pump would then be operating in a partial vacuum instead of liquid. Evidence of cavitation is increased vibration and reduced output which will cause damage to the pump. •
During the pump operation an officer or the pumpman must be on station at all times in the cargo control room to observe the tachometer and discharge pressure and be prepared to partially close ("throttle") the pump discharge valve if pressure falls off, or to shut down the pump if it loses suction
Multi-Pump Operation It is important to run all pumps at the same speed. If one pump runs slower than another does, it may stop pumping and heat up, possibly to a dangerous level. If there is high back pressure it is doubtful whether it is worth running all pumps. It may be better to run three out of the four pumps. Due to high shore back pressure, a pump running at reduced rpm may not be discharging at all; therefore, energy is converted to the heat and could be dangerous. •
Ensure all pumps run at the same speed and all are contributing to discharge
Shutting Down a Pump The pump discharge valve should be closed at the same time as the pump rpm's are reduced. When the pump has stopped, the suction valve should be closed. •
Pumps are not to be kept idling on standby.
Cargo Segregation The risk of contamination during discharge is just as great as during loading. Therefore, the vessel must ensure all precautions are taken in order to avoid accidents.
Speed of Discharging The Charter Party may contain a provision guaranteeing a certain rate of discharge, normally a pressure of 100 PSI at the ship's rail or discharge of entire cargo within 24 hours. Some installations are unable to receive at this rate resulting in the laytime being exceeded. To establish proof of excess time used and thereby ensure payment of demurrage, a written protest should be made and presented to the Terminal for their endorsement so as to protect the vessel from any future claims.
17.6
BALLAST OPERATIONS
Over pressurization of un-used deck cargo lines After every loading or discharging operation, it is important to ensure that deck cargo lines are drained. A good practice is to leave the cargo deck main (master) valves and drop line valves open so that all cargo remains can drop to the bottom line. When operating in areas of high ambient temperature, especially during daytime, a rise in temperature can substantially increase the pressure in deck cargo lines. Cargo line pressure should not be allowed to rise beyond the working pressure. Bolt tightness for flanges and expansion joints should be checked periodically. On new vessels, particular attention should be paid to flange bolt tightness till they settle down to seaway movements.

Ships with Segregated Ballast Tanks Ballasting and De-Ballasting sequences are to be integrated into the vessels cargo plans with due regard given to stress limitations of the vessel. Freeboard limitations at terminal and weather conditions must also be considered. Reference is made to the Company’s Ballast Water Management Plan which must be complied with.
Ships Using Cargo Tanks for Ballast Many older and smaller (max 29,999) product carriers have very limited segregated ballast tank capacity and therefore use their cargo tanks for departure as well as arrival ballast. •
When loading ballast after discharge it is important to keep the quantity of departure ballast to a minimum having regard for local regulations and weather conditions.
•
Where it is necessary to clean tanks for the sole purpose of arriving at a loading port with clean ballast, steps are to be taken to keep the quantity of arrival ballast at a minimum and in as few tanks as possible in order to save time for de-ballasting and mopping up.
•
Due consideration for weather and vessels stability requirements should always be taken into account.
De-ballasting Unless otherwise specified in the Voyage Orders, the vessel should arrive in the load port with clean ballast and decanted slops. When alongside, unless Terminal, local or international regulations require otherwise, the vessel will de-ballast to sea, prior to loading. Simultaneous de-ballasting and loading of cargo tanks should not be attempted unless there is at least two valve separations and the Master is satisfied that separation valves are tight. Permanent ballast may, of course, be discharged concurrently whilst vessel loading cargo. This may be required to increase the vessel's draft and reduce vessel's freeboard at the period when all clean ballast has been discharged and prior to loading to enable the loading arms to be connected, or to reduce the effect of wind in the light ship condition. If permanent ballast is insufficient to maintain the draft and freeboard limits required, then part cargo may be loaded prior to de-ballasting i.e. load, de-ballast, and re-load. During de-ballasting all clean ballast should be drained from the cargo tanks. At the end of de-ballasting, cargo lines should be drained into an aft most cargo tank and stripped using an eductor.
Opening of Sea Valves At the commencement of ballasting, minor pollution can occur when the sea inlet valve is first opened, if the pump and line to be used for this purpose has previously been employed for handling cargo. To avoid this problem, it is the common practice to start the pump prior to opening the outboard sea valve, for the purpose of creating a vacuum in the sea suction line which permits water to enter and prevents oil from flowing out when the sea inlet valve is opened. However, centrifugal pumps are not suitable for generating vacuum, especially against a closed suction, and, if started too quickly under no-load conditions, they are liable to over-speed and trip. This problem is not easy to resolve, because cargo pumps are not always fully controllable under light load conditions. However,

provided the head of oil/water within the ship's cargo system is kept below the head of water level of outside sea, it is possible to ensure that water flows in and not oil out. •
Although cargo systems vary substantially from ship to ship, the following procedures are generally applicable, and if adhered to will largely overcome the possibility of pollution occurring at this time.

th
Prior to Commencement of Ballasting, and Before Opening Sea Valves Set line for ballasting - with the outboard sea valve is to be kept closed. Drain all oil from the suction and discharge lines of the system to be used with the aid of the stripping pump or eductor if fitted. Alternatively, the bulk of the oil can be drained by dropping the line and pump contents into the aft emptiest tank. Particular attention should be paid to that section of the line on the discharge side of the pump, since an un-drained line will contain a substantial head of oil. Start up pump at reduced revolutions. If a pressure gauge or drain cock exists, check that there is no positive pressure on the section of the line between the pump and sea valve. As soon as the pump is running steadily, start to open the sea valve, increasing the pump speed as the pump starts to take up the suction. Care should be taken when increasing speed to avoid any possibility of tripping the pump through over-speed. On some vessels, it may not be possible to start the centrifugal pump unless it is primed. In this case, the stripping pump should be set to create a vacuum on the sea suction line. Maintain a close watch over the side so that, in the event of any oil appearing, the system can be immediately shut down.

CARGO HOSE HANDLING
The company considers cargo hose handling to be a critical operation and the following precautions are to be observed:
17.10
•
A responsible officer should check both the ship's gear to be used and, if required, the shore rig. Special attention should be given to the topping lifts. If the shore rigging seems unsafe in any respect, it should be tactfully discussed with shore personnel. Remember that if the rigging or the hoses fail, there is a serious risk of fire and explosion
•
Scuppers are to be plugged effectively. Drip trays are to be placed under manifolds to hold any drips and there should be plenty of rags and sawdust ready in case of any spillage on to the deck while disconnecting
•
Derricks should be well positioned to avoid the hose swinging when released. Tag-lines should have a good spread and be tight and lines should not be made fast to a winch
•
The hose is to be carefully inspected for cuts and breaks. After rigging, inspect for sweating, pinhole leakage, and leakage around nipples, hose-bends and chafing
•
During lifting, keep all men not actually engaged in the operation clear of the area, but have enough men readily available to do the job properly. Have them keep clear of bights and bends in hose
•
Where bolted connections are made, do not use fingers to line up bolt holes. A spike or wrench is much stronger and safer. All bolts to be used for tightening, which should be done evenly
•
Do not wet gaskets for a tight fit in freezing weather, it will blow when warm oil thaws it
•
When disconnecting hoses, rig preventer tackles or lines on either side to ensure that the hose does not whip when the last bolt is removed
•
Plug or cap the end of hoses before lowering to the shore
•
Drain hoses before stowing in racks and do not stow them near steam lines
•
Ships hoses are to be cleaned and blanked before storage

CARGO SAMPLING PROCEDURES
For the protection of the vessel, owner and time charterers’ interest, proper cargo sampling is very important and should be carefully attended to, as this is the only admitted evidence in many cargo claim litigation. The following ship samples are required in addition to the consignee samples required by the shipper.
Loading samples •
Line sample at the manifold at commencement of the loading
•
Foot sample if cargo being handled requires analysis of the first foot of cargo loaded
•
Final loading sample of each tank
•
The vessel shall take 3 x 1 litre samples of cargo at each manifold upon the commencement ( the from the first drop of cargo) of the loading and at each change of grade
•
The vessel shall also take 3 x 1 litre samples from the first tank of each grade when the surface has reached about 1 metre above the tank bottom
•
The samples must be carefully examined for compliance with colour, clarity and smell of product(s) and dirt/particulate matter. If non-compliance ascertained the loading must be stopped immediately and the attending surveyors and shippers advised. If the cargo determined to be off spec then shippers to be given Letter of Protest and P&I Club called
•
The samples must be sealed and labelled with voyage number, reference number, date, grade and line number, and, in respect of tank samples, also the tank no
•
Some samples such as POTDI, MDI extremely poison cargo samples are not to be kept onboard
•
If possible, any samples taken, should be sealed by the attending Cargo Surveyor
Discharge samples It is a sample taken from each tank prior to discharge. Line sample and composite sample at the manifold or discharge line connection, at commencement of discharge.

After discharge samples If after discharge there is cargo remaining in a tank, which cannot be removed by the vessels equipment, has become contaminated during discharge or has solidified sediments, the following must be done: •
The remaining cargo is to be accurately measured, by ullage and/or wedge formula, noting down the vessels trim and if the cargo is evenly spread on the tank bottom. The quantity and the way it was measured should also be stated on the "Dry tank certificate"
•
The residue is to be sampled, marked, sealed and stored in accordance with standard instructions
•
One set of samples taken, are to remain on board the vessel and one set is to be delivered to the vessels P & I correspondent or agent for analysis
•
The instructions for after discharge sampling are most important when fats, vegetable oils, molasses and fish oils are involved. However, it also applies to other cargoes that may settle during transit or cargoes that are contaminated during discharge
Samples of internal transfer If transferring cargo internally on board, samples should be taken as if it an actual loading and discharging operation.
Labelling of samples •
Name of vessel and voyage number.
•
Date and place, and if loading, discharging or transferring.
•
Name of product and eventually cargo number if any.
•
Tank no and if line/foot/tank sample.
•
Name of surveyor or on board person if taken by ship’s staff.
Sampling procedure Samples should be taken in clean bottles, rinsed with the cargo to be sampled, and sealed only in the presence of a ship's officer and the cargo surveyor. If the surveyor refuses to take or seal samples for the vessel, the ship's personnel must take such samples, and clearly make notation in the log book and on the sample label that surveyor refused to seal samples.
Storing of samples Samples should be stored in a special designed locker within the cargo area, away from the accommodation, equipped with adequate ventilation and sprinkler. The sample bottles should be placed in cell divided boxes or similar, to prevent damage, and be clearly marked USCG compatibility. Samples containing cargoes, which may react dangerously with each other, must not be stowed close to each other. Samples should be stored chronologically in order of voyages, enabling new people to locate a specific sample, in case of a cargo claim arising.

Retaining of samples All cargo samples shall be retained on board for a minimum for 12 months from the date of discharge. However, before disposing samples older than 12 months, contact Thome to make sure there is no claim involved, and it is safe to dispose of old samples. Inhibited cargo samples should not be retained on board after expiration date of inhibitor. Samples must only be disposed of in a proper way, in accordance with environmental legislation, after confirmation/arrangements have been received from the Company. Chemical Cargo Samples must not, under any circumstances, be disposed to slop/residual tank (mixed with other products) or “dumped” into the sea. Proper Sample Log entry to be made (sample nr/port/date/time/to whom the samples had been handed over). The Sample Disposal Certificate must be requested from the company/shore facility handling the disposed samples and the same to be attached to Cargo Sample Log.
Releasing of samples When delivering the consignee samples at the discharge port, a proper receipt has to be signed by the receiver and the receipt is to be retained onboard. In no case is the vessel to give away any samples without having any duplicate on board. If a claim arises, the official sample should not be released from the vessel without proper authority from the vessels P & I club or Thome, and then only against a proper receipt, with one copy remaining on board.
Recording of Samples A record book should be prepared for the cargo samples and should contain the following:
17.12
•
Date and place taken and voyage number
•
Number of samples received/taken
•
Commodity and cargo number
•
Type of sample (line/foot/tank/load or discharge)
•
When, where and date consignee samples given out
•
When, where, date, vessels sample given to P & I representative
SLOP DISPOSAL
In accordance with MARPOL, all slops should be discharged to slop facilities ashore where these facilities are available. The Master should inquire well in advance through the agents at all loading and discharge ports if slop facilities are available and the cost per ton of using the service. However, in most cases the agent will need to know the type and quantity of slops which the vessel needs to disposal of. This information should always be included in the first ETA notice to port agents. Masters are advised to liaise closely with charterers and Thome for the proper disposal of slops. Copy of shore receipts of slops to be attached in the Oil Record Book.

Prior to all Ship to Ship Transfer Operations, Thome’s Singapore office must be informed for insurance purposes. Details of the fixture are to be made known to TSM.
STABILITY PRECAUTIONS
Double Hull Tankers without Centreline Bulkhead Master and Deck Officers need to be aware of the operational constraints which can arise during the loading and discharging operations of double hull tankers. The free surface effect of cargo and ballast tanks, may lead to negative GM with consequent sudden “Heel Over” to an angle of loll. •
Such sudden “Heel Over” may rupture the ship’s manifold connections and break the vessel’s mooring ropes, all with disastrous effect.
•
To prevent such accidents it is important that all Deck Officers are familiar with the vessel’s stability criteria: o
during cargo loading and or discharging
o
ballasting and or deballasting operations, especially when done simultaneously, when maximum free surface effects may create an unstable condition causing the vessel to suddenly list (angle of loll)
o
instructions related to free surface effects
o
Any particular restrictions on the vessel pertaining to the number of slack cargo tanks to be maintained.
o
Further details of intact stability on double hull tankers can be found in th ISGOTT 5 Edition Chapter 11.2. The guidelines contained in ISGOTT should be fully complied with at all times.
If a loss of stability becomes evident during loading or discharge, all cargo, ballast and bunker operations must cease and a plan be prepared for restoring positive stability. If the vessel is at a terminal, this plan should be agreed by the terminal representative and it may be necessary or prudent to disconnect the loading arms or hoses. The specific action required to restore stability will be determined by the vessel’s detailed stability information in relation to a particular condition. In general the following principles apply: •
The vertical centre of gravity must be lowered in the most effective way
•
Where slack double bottom tanks exist, these should be filled, starting with those on the low side, followed by those on the high side
•
If the pressing-up of slack double bottom tanks is insufficient to regain stability, it may be necessary to consider filling empty double bottom ballast tanks. It must be recognised that this will initially result in a further loss of stability caused by the additional free surface effect. However, this will soon be corrected by the effect of the added mass below the vessel’s original centre of gravity
•
No attempt should be made to correct a list by filling compartments on the high side as this is likely to result in a violent change of list to the opposite side
•
The restraint provided by moorings should be considered. To attempt to control a list by adjusting mooring rope tension could be dangerous and is therefore not recommended

OPERATIONAL CHECKS FOR TANK VESSEL DURING SEA PASSAGE
During sea passage the following controls are performed based on nature of cargoes carried. The understated controls are performed by qualified and trained personnel. Any abnormality must be promptly reported to the master who shall take necessary steps.
Daily Control of Bilge and Pump Room Pump room bilges are to daily monitored for hydrocarbon content. Such monitoring should also include sounding to detect cargo or water leakages.
Control of Valves Cargo Segregation or Mixing or Contamination The slightest contamination of cargoes either by mixing of grades or by mixing of cargo and water will, often, ruin the entire contents of a tank resulting in heavy claims. It is the vessel's responsibility to avoid any kind of mixing or contamination and the utmost care should be taken to eliminate accidents. Tagging of valves When the vessel is carrying more than one grade, it is required to tag the valves. If the vessel has loaded cargo in different groups and the valves are readily distinguishable by different colours. In any other case, tagging of valves serves the same purpose. Avoid inadvertent access or operation of valves It is encouraged to establish procedures to avoid inadvertent access or operation of any valve during the sea passage. This may be carried out by keeping the cargo control room and/or hydraulic room locked. ‘Lock out – Tag out’ procedure may also be used to identify and isolate the grades. Manufacturer’s instructions are referred to avoid any inadvertent opening of the valves, due to drop in the hydraulic pressure or other similar cases. Segregation of venting lines In case the vessel has common venting lines, the tank isolation valves are to be kept shut and the Inert Gas pressure monitored regularly. This is carried out to avoid vapour contamination. The tank isolation valves are locked to avoid inadvertent operation and the Chief Officer should have the keys to the locks.
Cargo Tanks Level Any variation in the tank level shall be immediately investigated and the necessary action taken to prevent a hazardous situation and pollution
Cargo Tank or Line Pressure In ships fitted with an inert gas system, the topping up operation is to be started whenever the cargo tank pressure drops to 100 mm H2O.

Tank / Line Over-Pressurisation and Under-Pressurisation During sea passage, over-pressurisation of cargo tanks is due to compression of the ullage space by the over-release of vapour generated due to increase in the temperature of the cargo. Underpressurisation can be caused by expansion of the ullage space by the inadequate release of vapour due to fall in the temperature of the cargo. The resulting over or under-pressure in the tank or line may result in serious deformation or failure of the tank or line structure and, which can seriously affect the structural integrity of the ship and could lead to pollution. Precautions and Corrective Actions Tank pressures are required to be monitored regularly. In case the pressures fall below 100 mm wg. Inert gas plant is to be used in order to top up the pressure. In case the pressure increases, it may have to vented off using mast riser or PV valves. In case of releasing toxic vapours, reference is drawn to ECM part B section 13. After completion of loading, cargo lines too suffer over and under pressurization due to increase or fall in the temperature of the cargo in the line. Vessels are guided to vent off the lines one by one, by crack opening the drop valve and the goose neck valve to the cargo tank.
Cargo Temperature When vessel have received cargo which requires heating during the voyage, it is imperative that the heating instruction given by the shipper is well studied. Generally, heating instruction require the vessel to keep min/max temperature during the voyage and also min/max temperature before discharging as well as maximum temperature rise per day. Prior loading, the Master should cross-check that the maximum temperature for the cargo is well below the maximum temperature for the tank’s coating can bear. Reference should also be made for the maximum temperature for the seat-rings of the valves. Cargo temperature shall be monitored and recorded at least daily and if in hot climate e.g. warm seawater and sun warming up the deck, a more frequent check may be necessary. If temperature starts rising towards the dangerous level, cooling systems must be put into operation. Cooling can be done by circulating cold fresh water in the heating coils, and/or by flushing deck by ambient seawater
Inspection of Cargo Lines Any leakages, during the loading shall be identified and possibly immediately repaired taking into account the flammability and hazardous characteristics of the cargo. In case of multiple grades loading, neither the cargo lines are to be pressure tested, nor the cargo pumps should be tried out. In case of product tankers involved in regular multiple grade loading, the pressure testing of lines and trying of cargo pumps should be carried out during tank cleaning.
Gas Detection and Sounding of Empty Tanks Adjacent to Cargo Tanks All tankers without fixed gas detection systems for void and ballast spaces within the cargo tank area, should have these spaces regularly monitored for hydrocarbon content. Such monitoring should also include sounding and ullaging of the empty spaces to detect cargo or water leakages. Non-cargo spaces within the cargo tank area should be monitored as follows: •
Soonest after each loading operation
•
Everyday during loaded passage and immediately prior to arrival at port
CONTROLLED
Revision: 09 Dec 2013 Approved by DPA/DMR Page 21 of 43

•
Prior to all ballasting
•
In connection with any unusual event such as grounding, collision, contact damage, after a period of very heavy weather or any other unforeseen operational problems
•
Every third day during ballast passage (sounding or ullaging only)
Where ships are engaged on short coastal voyages, which make the above regulations impractical to follow, visual inspection of the tanks or the ballast water is considered a suitable alternative measure. The test results of this monitoring should be entered. During voyage there might be a leakage from the cargo tanks into cofferdams, double bottoms, etc. Therefore, all void spaces should be gas-monitored everyday and recorded.

CARGO VAPOUR EMISSIONS CONTROL
VEC Systems During loading of volatile or toxic cargoes, venting must take place through approved systems that expel vapour clear of the tank deck area. Vapour emission control system regulations are to be followed where and when applicable. All ships should conduct and log details of training in operation of VECS prior to arrival at any terminal that will be using the VECS equipment. Ships fitted with VECS have an approved operation and training manual onboard. Ships staff should be acquainted with this manual which forms the basis of all training. As a general guide, training should include discussion as outlined below followed by familiarisation of the system.
Settings for Pressure Sensor and Alarm Systems If a vapour recovery system (VRS) is fitted, a pressure alarm will be fitted in the vapour return line. This must be set to activate before the p/v valve design pressures. The USCG requires this alarm to be set to 90% of the designed p/v valve actuation settings.
Purpose of a Vapour Control System United States Coast Guard Regulations for Marine Vapour Emission Control Systems are to be used as a standard whenever such systems are required by individual States within the U.S. under the U.S. Clean Air Act. The Vapour Emission Control System consists of two basic parts, viz: •
CONTROLLED
A "Vapour Collection System” o
Defined by the USCG as: "An arrangement of piping and equipment used to collect vapours emitted from a vessel's cargo tanks and to transport the vapours to a vapour processing unit".
o
All tank vessels and terminals involved in the transfer of vapours from crude oil, gasoline blends or benzene must be fitted with a Vapour Emission Collection System.
o
This document relates only to the part of the Vapour Collection System required to be installed on tank vessels. These regulations apply to tank vessels which load or are engaged in lightering operations involving the crude oil gasoline blends or benzene. Revision: 09 Dec 2013 Approved by DPA/DMR Page 22 of 43

OMD Document No. 017 Tank Vessel Operations
A "Vapour Processing Unit" o
Defined by the USCG as: "The components of a Vapour Control System that recovers, destroys or disperses vapour collected from a vessel".
o
The Regulations related to Vapour Processing Units are not applicable to tank vessels.
Principals of a Vapour Control System Basic requirements which are applicable to all tank vessels involved in the loading and discharge of the stipulated cargoes, viz: •
The provision of permanently installed vapour collection piping from the cargo tanks to a clearly marked standard vapour discharge connection situated near the cargo manifold. Individual vapour discharge connections located in the vicinity of each cargo tank may be fitted in lieu of a common vapour discharge connection for tankers carrying certain types of cargo where cargo segregation needs to be maintained. However, if cargoes with incompatible vapours are loaded simultaneously, the vapours must be kept separate throughout the entire vapour collection system.
Components of a Vapour Control System •
The vapour collection piping must be provided with a means to collect liquid condensate, e.g. drains should be fitted at every low point in the line.
•
The vapour collection piping must be electrically bonded to the hull and be electrically continuous.
•
The vapour collection system must have a means to isolate the inert gas supply from the vapour collection system, (the inert gas main isolation valve required by SOLAS 74 is acceptable). All inert gas main on crude oil and product tankers may be used as the vapour collection piping, subject to it being modified to comply with the VECS requirements.
•
Where vapour transfer hoses are provided on board they are to have a design burst pressure and a working pressure as required by the Regulations, be abrasion and kink resistant and have a clearly marked standard vapour discharge connection flange.
•
A manually operated isolation valve, with open/shut indicator, is to be provided at the vapour discharge connection.
•
Each cargo tank must be equipped with a closed gauging device and high level and overfill alarms. The overfill alarm system must be independent of the cargo gauging device. If installed after 23 July 1990 the high level and overfill alarms are to be independent of each other.
•
The vapour collection system must not interfere with the proper operation of the cargo tank venting system.
•
The vapour collection system must be equipped with a pressure sensing device which activates a high and low pressure alarm and provides a pressure indication at the cargo transfer control position.
•
Additional requirements which are applicable only to vessels engaged in lightering or topping off operations with vapour balancing. The additional requirements are dependent upon whether the cargo tanks of the vessels receiving and discharging cargo are inerted or not viz:
CONTROLLED
Revision: 09 Dec 2013 Approved by DPA/DMR Page 23 of 43
OMD Document No. 017 Tank Vessel Operations
THOME SHIP MANAGEMENT PTE LTD
o
Vapour balancing is prohibited when the cargo tanks on a vessel discharging cargo are inerted and the cargo tanks on the vessel receiving cargo are not.
o
When the cargo tanks on the vessel receiving cargo and the vessel discharging cargo are inerted the service vessel must be provided with: o
A means to inert the vapour transfer hose prior to cargo transfer.
o
An oxygen analyser with a sensor or sampling connection fitted within 3 metres of the vapour discharge connection point.
Note: - A "Service Vessel" has been defined by the USCG as a vessel which transports bulk liquid cargo between a shore facility and another vessel. o
If the cargo tanks on a vessel discharging cargo are not inerted, the service vessel must be fitted with a detonation arrestor of a type acceptable to the USCG.
Irrespective of whether the vessels are inerted or not, an electrical insulating flange, or one length of non-conductive hose, must be provided between the vapour collection system connections of the service vessel and vessel being serviced.
Hazards Associated With a VEC System Caution must be exercised to avoid the possibility of tank over pressure or vacuum, the return of cargo through the system or the mixing of incompatible vapours. The above mentioned alarm system is to give warning of these hazards and allow remedial action to be taken. Officers should be aware of action to take in event of alarms and Chief Mate must be familiar with the testing and demonstration of alarms. During loading, cargo will cause vapour to be displaced via the VECS pipeline to the shore collection manifold. Care needs to be taken to control the loading rate to avoid over pressure or vacuum of the VECS system. A cargo tank should never be opened to atmosphere or gauging or sampling purposes while the vessel is connected to the shore vapour recovery system, unless, the tank is isolated from the vapour line, is not being loaded, and precautions are taken to reduce the pressure from the vapour space within the tank. All hazards normally associated with the transfer of petroleum / chemical cargoes are still present. All procedures banning smoking, hot work and use of protective clothing must be rigidly enforced
Operating Procedures •

TANK CLEANING GUIDELINES
Reference is made to Dr. Verwey’s Tank Cleaning Guide for procedures to be adopted whilst tank cleaning, or any operator specific instruction manuals, such as provided by Stolt Niesen, for guidance on cleaning between specific cargoes.
Compulsory Tank Washing and Cleaning Safety Precautions Water is the most common washing medium for flushing the bottoms of cargo tanks, or for cleaning them using tank washing machines. It is readily available in large quantities, it is an efficient cleanser and on most chemical tankers the wash water can be heated when necessary. Nevertheless, it is sometimes necessary to use small quantities of chemical additives or detergents as a cleaning agent in order to improve the cleaning effect. However, in some situations water will not be used. Water must not be used in the case of chemicals that react with water, and a washing medium other than water may also be used for commercial reasons. It may be permissible to use ventilation to remove cargo residues and gas free a cargo tank after a highly volatile cargo has been carried. In every case, the full safety aspects of the operation should be considered. When tank cleaning in port, relevant regulations and limitations established by the port authority and terminal should be complied with. After carrying a low flash point cargo, a flammable vapour mixture should always be suspected until tests have established that the atmosphere is non-flammable. Equal care is necessary after carrying a non-volatile flammable cargo at a temperature above its flash point, or after discharge of any cargo or ballast that had been loaded into a tank that was not free of flammable vapour. Toxic vapour in harmful concentrations should also be assumed after unloading cargoes which have a vapour inhalation hazard. Cargo vapour, toxic or flammable, should be suspected in cofferdams or any other space within the cargo area into which such cargoes may have leaked. CONTROLLED

Tank Washing Atmospheres Tank washing may be carried out in one of the following atmospheres: •
Inert
•
Non-inert
Inert This is a condition where the tank atmosphere is known to be at its lowest risk of explosion by virtue of the atmosphere being maintained at all times non-flammable through the introduction of inert gas and the resultant reduction of the overall oxygen content in any part of any cargo tank to a level not exceeding 8% by volume while under a positive pressure (see ISGOTT Section 7.1.5.1). The requirements for the maintenance of an inert atmosphere and precautions to be observed during th washing are set out in ISGOTT 5 edition Section 7.1.6.9 and provide the most certain level of control of an atmosphere during tank washing operations. In fire triangle terms, this method physically removes and controls the ‘oxygen’ side of the fire triangle. To satisfy the control measures for washing in inert atmospheres see ISGOTT Section 7.1.6.9. During tank washing operations, measures must be taken to verify that the atmosphere in the tank remains non-inflammable (oxygen content not to exceed 8% by volume) and at a positive pressure. Before each tank is washed, the oxygen content must be determined, both at a point 1 metre below the deck and at the middle level of the ullage space. At neither of these locations should the oxygen content exceed 8% by volume. Where tanks have a complete or partial swash bulkhead, the measurement should be taken from similar levels in each section of the tank. The oxygen content and pressure of the inert gas being delivered during the washing process should be continuously recorded. If, during washing, the oxygen content in the tank exceeds 8% by volume or the pressure of the th atmosphere in the tanks is no longer positive, guidelines contained in ISGOTT 5 Edition Chapter 11, section 11.3.4.2, 11.3.5 should be followed, in recognition that tank washing and gas freeing operations in these conditions (O2>8% and or negative pressure inside the tanks) are considered to present a likelihood of increased risk and additional control measures are required to reduce risks to as low as reasonably practicable.
Non-inert A non-inert atmosphere is one in which the oxygen content has not been confirmed to be less than 8% by volume. In recognition that tank washing and gas freeing operations in non-inert atmospheres are considered to present a likelihood of increased risk, additional control measures are required to reduce the risk of operations to as low as reasonably practicable. These controls must address two sides of the fire triangle namely – ‘Fuel’ and ‘Sources of Ignition’. Non-inert cargo tank washing should only be undertaken when both the source of ignition and the flammability of the tank atmosphere are controlled. To achieve this, the following precautions to control ‘sources of ignition’ and ‘fuel’ MUST be taken for tank washing operations in a non-inert atmosphere condition. Guidance in this regards can be obtained from ISGOTT sec 11.3.5.2 A flow chart showing steps to the control the “fuel” while tank washing in the non-inert tank atmosphere method is included in the procedure.

Precautions when tank washing in an inert atmosphere Although the atmosphere in a properly inerted tank is incapable of burning, the following precautions should be observed: •
When portable washing machines are used, all hose connections should be made up before the washing machine is introduced into the tank. Connections should not be broken until after the machine has been removed from the tank. However, to allow draining of a hose, a coupling may be partially opened and then re-tightened before the machine is removed.
•
The tank should be kept drained during washing. Washing should be stopped to clear any build-up of wash water.
When there is a need to maintain an inert atmosphere during tank washing, the following points should be observed: •
The purity and pressure of the inert gas being delivered during the washing process should be monitored.
•
Before each tank is washed, the oxygen level in the tank should be determined both at a point about 1 metre below the deck and at the middle level of the ullage space. At neither location should the oxygen level exceed 8% by volume.
•
If during washing the oxygen level in the inert gas supply exceeds 8% by volume or the pressure of the atmosphere in the tank is no longer positive, washing should be stopped until satisfactory conditions are restored.
Some cargoes carried under an inert blanket are not flammable but the atmosphere is inerted for cargo quality reasons. In this case, gradual decay of the inert atmosphere during cleaning is acceptable. In all other cases, if the inert atmosphere is not maintained then the procedures used and precautions taken should be as for a non-inert atmosphere.
Precautions when tank washing in a non-inert atmosphere Most tank cleaning on chemical tankers is conducted in a non-inert atmosphere. In all cases after carrying a flammable cargo, the atmosphere in an empty tank should be treated as flammable. The only way to guarantee that an explosion cannot occur during washing in a non-inert atmosphere is to make certain that there can be no source of ignition. Good tanker practice will avoid all normal sources but, in addition, the following precautions should be taken if the risk from static electricity is to be eliminated: •
Before washing, the tank bottom should be flushed with water and stripped. The piping system, including cargo pumps, crossovers and discharge lines, should also be flushed with water. The flushing water should be drained to the tank designated to receive slops. This operation may not be necessary if the ship is fitted with an efficient stripping system, and the cargo tank and pipelines have been stripped as detailed in the ship's Procedures and Arrangements Manual. o
If cargoes are highly water reactive this operation must not be carried out.

When portable washing machines are used, all hose connections should be made up before the washing machine is introduced into the tank. Connections should not be broken until after the machine has been removed from the tank. However, to allow draining of a hose, a coupling may be partially opened and then re-tightened before the machine is removed.

•
The total water throughput per cargo tank should be kept as low as practicable and must in no case exceed 110m3 per hour.
•
The tank should be kept drained during washing. Washing should be stopped to clear any build-up of wash water.
•
Re-circulated wash water should not be used, because it may increase the generation of static electricity.
•
Sounding rods and other equipment must be introduced through a sounding pipe reaching close to the bottom of the tank and earthed to it. If a sounding pipe is not used then the additional precautions in paragraph 7.3.5 below should be followed.
•
No other material that may create a spark or static electricity should be lowered into the tank.
•
Steam should not be injected into the tank.
Further information on electrostatic precautions during tank washing is given in Appendix D.
Chinese Baselines Please refer to HSSEQ Circular 40 – 2013 for understanding of Chinese baselines with respect to Marpol and other international conventions.
Precautions for sounding tanks when not using a sounding pipe If a sounding pipe is not used, it is essential that any metallic components of the sounding rod or other equipment are bonded and securely earthed until removal from the tank. This precaution should be observed during washing and for five hours afterwards, unless the tank is continuously mechanically ventilated after washing, in which case the delay period can be reduced to one hour. During the delay period: •
An interface detector of metallic construction may be used if earthed to the ship by means of a clamp or bolted metal lug.
•
A metal rod may be used on the end of a metal tape which is earthed to the ship.
•
A metal sounding rod suspended on a natural fibre rope should not be used even if the end at deck level is fastened to the ship, because the rope cannot be completely relied upon to act as an earthing path.
•
Equipment made entirely of non-metallic materials may in general be used: e.g. a wooden sounding rod or float may be suspended on a rope without earthing.
•
Neither ropes made of synthetic polymers nor chains should be used for lowering equipment into cargo tanks.
Steaming of cargo tanks Because of the hazard from static electricity, steam should not be introduced into cargo tanks where there is a risk of the presence of a flammable atmosphere. It should be borne in mind that a nonflammable atmosphere cannot be guaranteed in all cases where steaming might be thought to be useful.

Cleaning of cofferdams or double bottom tanks If it is necessary to clean cofferdams or double bottom tanks into which cargo liquids or vapour could have leaked, the same precautions should be observed as when cleaning cargo tanks.
Free fall of wash water in slop tanks It is essential to avoid the free fall of slops or tank washing water in a receiving slop tank unless the tank is inerted (see Appendix D for the generation and control of static electricity). Washing water or slops should be transferred to the receiving tank through the cargo system. If a different arrangement is necessary, then to avoid splashing the receiving tank should be filled to a depth of at least 1 metre, or sufficient to ensure that the discharge inlet is well below the surface of the water.
Purging and Gas Freeing A “Tank Scope” is used to measure the percentage of hydrocarbon vapours in an inert tank. The instrument is used when “purging” hydrocarbons prior to gas freeing with air. When the Tank-Scope indicates hydrocarbons are less than two percent (2 %) by volume, fresh air may be introduced without placing the tank atmosphere in the flammable range. •

Cleaning after Fuel Oil Other Companies have found from experience that washing with cold water can be an advantage as a first step in tank cleaning after certain fuel oil cargoes. Since a considerable saving in tank washing expenses is achieved by not using heated water for tank washing, the cleaning after fuel oil shall, therefore, commence by washing one tank with cold water and one tank with heated water in order to compare the effect produced. If inspection of the two washed tanks shows that good results can be achieved with cold water, preliminary washing with cold water is to be continued, whereupon any necessary final washing with hot water shall be undertaken with chemical additives as appropriate.
Flushing of Pipelines Before commencing tank cleaning, pumps and pipelines shall be washed through and the wash water pumped to slop tanks.
Steaming of Cargo Lines Vessels are advised that when cargo lines have to be steamed, it has to be accomplished by means of a temporary connection. This connection should be a hose and is to include a stainless steel nonreturn valve in series with a normal valve. If such connections are not available, the vessel is to raise an order and fabricate as required. Under no circumstances are permanent connections to be made between the steam system and the cargo system.
Cleaning Of Pump-Rooms Whenever tank cleaning is undertaken, the pump-room shall be cleared of oily residues and any sediment found.
Draining Of Pipelines After every tank cleaning all tanks, pipelines and pumps shall be drained of water to the greatest possible extent.

Mopping Up in Tanks Preparation of tanks to receive fertilizer, jet fuels and kerosene requires that all water remaining in tanks is mopped up, that pumps, and pipelines in tanks are drained completely. The ship will receive detailed instructions if loading of other products requires mopping up in tanks. •
Mopping up of water and draining of pumps and pipelines shall be carried out immediately before arrival at load port to coincide with arrival and tank inspection time (where visual inspections are stipulated) whereby vessel can ensure that mopping up shall not be undertaken more than once.
•
If chemical additives have been used for tank washing purposes, gas checks with appropriate Draeger tubes should be carried out to check atmosphere before entering.
Lifting of Loose Scale All loose rust scales after tank cleaning must be removed from the tanks and disposed of prior to arriving in the loadport ready for inspection.
Safety Regulations During every tank cleaning operation the safety regulations in force are to be strictly adhered to. ISGOTT tank cleaning procedures as included in ISGOTT Chapter 11.3 are to be strictly followed at all times. •

It is essential that any discharge into the sea of oily water only be undertaken in accordance with the directions indicated in the "Clean Seas Guide for Oil Tankers" Guide and MARPOL requirements. All crew members who are in charge of ballast discharge and removal of water from slop tanks should be thoroughly familiar with the contents of "Clean Seas Guide for Oil Tankers" Where washing of cargo tanks and flushing of pipelines is undertaken, after carriage of liquid fertilizer, discharge of wash water and fertilizer residues directly overboard must only take place in accordance with the vessels Procedure and Arrangement manual, incorporating the MARPOL regulations.
Cleaning after Vegetable and Animal Oil For purposes of tank cleaning, vegetable and animal oils may be grouped as follows: •
Drying Oils / Semi-Drying Oils
•
Non-Drying Oils
Drying Oils, Semi-Drying Oils Residues from these oils absorb the oxygen in the air and drying up with the result that a hard surface is formed which prevents washing away of oily residues. It is important, therefore, to start tank washing as soon as possible after the discharge of these products. If some length of time is likely to elapse without complete cleaning being undertaken, the tanks should be washed down with cold water to prevent the products from drying up. It is recommended to wash tanks for not less than two hours with sea water heated to about 50 degree Celsius (the wash water temperature must not exceed 50 degree Celsius). •
Where inspection for the tanks shows that the residues has dried up and cannot be washed away, cleaning chemical, as advised by Thome, concentrated foam is to be applied and left for about 30 minutes whereupon the residues is to be washed away with heated wash water (max. 60 degree Celsius).
Non-Drying Oils The tanks are to be washed for two hours with sea water heated to 60 degree Celsius. The tanks are to be inspected after washing and any necessary final washing carried out with heated sea water.

CARRIAGE OF MOLASSES
There are two main types of molasses: •
Beetmolasses, made from sugarbeet residue o
•
Beetmolasses has a pH of 7 - 7.5, occasionally pH 8. It is neutral or a little alkaline.
Cane molasses, made from sugar cane residue o
Cane molasses has a pH of 7 - 6.5, occasionally pH 6. It is neutral or a little acidic.
A low pH will show that the molasses is already old. The pH can be checked with indicator paper. Part of the glucose in the molasses can turn into ethanol and carbonic acid. The ethanol can further become vinegar. The transformation of the glucose to ethanol and later to vinegar is by hot fermentation. This can be accompanied by a temperature increase. The fermentation process reduces the quality of the molasses. A lot of ethanol makes the molasses unsuitable for making penicillin. The carbonic acid caused foaming. Fermentation can be reduced or stopped by adding air into the molasses by air hoses or via a drop line connection. If Fermentation occurs, Thome should be consulted. The addition of water can prevent foaming, but most receivers do not want water in their cargo. Although the water does not affect the quality of the molasses, the receiver does not want to pay for water. There is great variation in the viscosity of molasses, depending upon the sugar content. The word used is 'brix'. The lower the viscosity, the easier to pump. The 'brix' is measured with a 'sugar refractometer'. CONTROLLED

Molasses is used for human consumption through the alcohol and pharmaceutical industries. It is also used for animal consumption. Different interpretations exist concerning the maximum temperature, which varies from 40.5 deg C to 43 deg C. Excessive heating can scorch or burn the molasses, reducing the quality and leading to claims. The molasses may become unfit for human and animal consumption. •
Due to air in the molasses and the transformation of the glucose to carbonic acid, the cargo can expand - so check the ullages. The SG of molasses is between 1.2 and 1.45, ensure that the tanks are not filled and there is enough ullage for cargo expansion
When loading over the top keep the free fall to a minimum. Too much air will enter the molasses. This will form foam and create discharge difficulties. Air surfaces very slowly through the thick top layer of the molasses. As far as possible, try not to strip with the Cargo Pump. Strip tanks between discharge ports to reduce delays when possible.
Loading Molasses Pressure test Heating Coils and rectify or isolate any leakage in the ballast passage before loading. The tanks for loading are to be inspected for cleanliness, dryness and fitness to carry molasses and a certificate issued prior to loading. Request instructions concerning the sealing of the sea valves. Whenever the shipper states that this is not necessary, obtain a written statement of that fact. The cargo should be loaded warm - about 40 deg C. Load Centres as far as possible as they are easier to strip and their heating coils are better for maintaining the temperature. All cargo line valves are to be shut. Prevent molasses from entering the lines. Load 'over the top' with hoses. Reduce free fall to a minimum to prevent aeration of the molasses. Gradually start heating - according to instructions. Keep a careful check on temperature. Molasses has a high SG so check the loading manual for instructions concerning partial loading of tanks. Instructions can be requested from Thome office. Except where instructions are received to the contrary, Molasses may be allowed to cool after loading until about 10 days prior to arrival at the discharge port. Care must be taken as Molasses takes very long time to heat. The lower layer might go above the Charterer instructed temperature, while the top layer may still be below the required discharge temperature. If heated fast to achieve the required discharge temperature prior to arrival, there is a danger of crystallization around the coils. Some shippers instruct that loading temperature be maintained throughout the voyage. The cargo consequentially requires less heating and so the risk of crystallisation is reduced. However, with inferior qualify Molasses (old Molasses which has a lower PH) maintain the temperature above 27 deg C. Heat the cargo gently until the upper layer is warmed up before increasing the heating. •

If no instructions are received at the load port concerning the required discharge temperature, contact Charterer and or operators
The required discharge temperature at the disport varies according to the receiver: Amsterdam 40 deg C and Hamburg 45 deg C. The absolute maximum discharge temperature will be 45 deg C as above this there is a danger of scorching and crystallisation. •
Before and after loading take a draft survey. Take survey at each load port, before, and after each discharge
The draft survey is most important in proving that the vessel is fully discharged. The freight payable is determined using out-turn figures. It is better to have a lower figure from the draft survey and a subsequent lower B/L figure. Cargo claims are lodged for any shortage in the outturn It is most important to seal the sea valves in the load port. If they are not sealed by the shipper then the reason must be entered in the logbook. The ship should seal the sea valves itself and record details in the logbook. Failure to comply with the above will lead to cargo claims if the out-turn is low. It will be claimed that the vessel lost cargo on route.
Care during Transit Check cargo temperature, heating to monitor as per shipping instructions. Prior to arrival gradually increase temperature as required for discharge, maybe to 45 deg C
Molasses Discharge If possible, use the Butterworth system to heat water from the Aft Peak. Use the forward cargo line, Butterworth connections to flush all lines and pumps with hot water. It is possible to use a closed cycle and return water from the cargo system to the Aft Peak Tank. After all lines and pumps are thoroughly warmed, strip out all water from the cargo system. Purge lines with steam. Vessel is now ready to discharge - Line up and start. Start the pump - check for positive suction pressure. Gradually increase revs and adjust discharge valve to maintain positive pressure. Check that the pump operation is normal. Check pump temperatures regularly for over heating. Additional water cooling may be needed. By carefully monitoring the pump speed and discharge valve position, the discharge can be expedited. •
It is possible to pressurise tanks with air to assist draining. Pressurise to about 0.13 atmospheres.
•
If permitted, the tanks can be steamed to assist drainage and reduce residues.
•
As soon as cargo pumps are stopped, the lines and pumps must be flushed with warm sea water to prevent the molasses solidifying.
•
Pump tanks dry with portable pumps.
•
When each tank is almost dry, hang steam hoses at the middle of tank and steam for about 30 - 60 minutes, this should clean any clingage off the sides.
•
Prior to any steaming, check that it is permitted by the receiver and or surveyor.

If it is necessary to ballast during discharge, first obtain permission from the surveyor or receiver in writing. If the dock water is clean enough, ballast via hoses over the top. Use the Butterworth heater to pre-warm ballast water. Heat the water in ballast tanks using coils.
This is necessary to avoid cooling of any adjacent tanks containing molasses or the cooling of pipelines. •
If it is not possible to use the Butterworth System, use a ballast pump to ballast over the top.
•
Be certain to obtain a Dry Certificate prior to ballasting any tank.
•
After loading and before discharge take ullages and prepare an ullage report.
Quantity cannot be calculated from ullages due to the variation in density and temperature in each tank. Accurate ullages may not be possible due to foaming of the surface. However, the ullage report can be used to show that there is no significant change during the voyage and therefore, no cargo loss. •
After discharge, obtain a Dry Certificate from the surveyor. The certificate must only be endorsed EMPTY - no other remarks are to be allowed
A cargo claim will result if "un-pumpable" is endorsed.
Cleaning after Molasses As soon as possible after the completion of the discharge, clean the tanks with warm sea water. Molasses residue attacks the tank coating and must therefore be removed as early as possible. Note that steaming and the use of fresh water will cause foaming. Use salt water for cleaning tanks. Remember that during cleaning gases are generated which will suffocate. Check tanks for Oxygen before each entry. Alcohol fumes and C02 can form in the ullage space above the molasses. There may be no oxygen present. After the carriage of molasses, it is important to thoroughly clean tanks, lines and pumps. Molasses residues will discolour subsequent cargoes.

CARGO HANDLING AND OPERATIONAL TESTS DURING THE VOYAGE
Cargo Heating When vessel has received cargo which requires heating during the voyage, it is imperative that the heating instructions given by the shipper are understood and strictly complied with. Generally, heating instructions will require the vessel to keep min/max temperature during the voyage and also min/max temperature before discharging as well as maximum temperature rise per day. Cargo temperature shall be monitored and recorded at least daily and if in hot climate e.g. warm seawater and sun warming up the deck, a more frequent check may be necessary, in order to prevent a vigorous self-reaction.
Monitoring Void Spaces During voyage there could be a leakage from the cargo tanks into cofferdams, double bottoms and void spaces. See Section 17.15 – Gas Detection in void and ballast spaces.
Preventing Vapour Loss •
Monitor escape of cargo vapour by checking PV valves

Prevention of Grade Contamination by Cargo Vapour Contamination of cargo is possible if cargoes of different vapour pressure are carried on a tanker with a common venting system. •
Isolate the venting systems for the two grades if possible
•
Close all the cargo tank independent inert gas isolating valves on the on the inert gas system and use the individual PV valves for each tank (if fitted) for pressure control
•

Pre-arrival Checks, Tests and Inspections The following operational tests, inspections and checks are performed during the laden sea passage and before the vessel's arrival at the discharge port. The time when the tests may be performed will be determined by the trade of the vessel but generally should not be less than 3 days before arrival if possible. This will ensure that there is plenty of time to rectify any defects discovered during the test routine.
Water Dips Make a full set of water cuts for cargo tanks and maintain records.
Hydraulic Systems Activate hydraulic system and check for leakage. Ensure that the motors are working properly. Check operation of valves. Check operation of high and low pressure alarms, low oil level and auto stop / start systems. Overhaul portable hydraulic hand pumps if necessary.
Inert Gas System Test the Inert Gas system, using each fan and venting inert gas to the mast riser. Check operation of pneumatic suction and discharge valves of the inert gas plant and the operation of the fixed oxygen analyzer together with the remote read-out in the cargo control room. Check the operation of the manual block valves and non-return flap valves on deck. Check control equipment for the inert gas system including high temperature, high / low / low-low pressure alarms and oxygen alarms. Calibrate portable oxygen meters.

GENERAL INFORMATION
Introduction and cleanliness standards Tank cleaning is carried out to: •
Prepare tanks for the carriage of the next cargo.
•
Prevent the build-up of oily residues.
•
Facilitate gas-freeing and tank entry for repairs/tank mopping.
•
Comply with Charter Party requirements.
•
Comply with MARPOL regulations.
•
In extreme circumstances, prepare tanks for the carriage of clean ballast.
•
It can be accomplished by means of portable or fixed tank washing machines, or sometimes a combination of both using hot, cold, fresh or sea water and/or chemical detergents singly or in combination.
In order to reduce unnecessary bunker consumption, impact on the environment and associated costs, vessels should only tank clean when necessary. Also, introducing water into the cargo system is not always the best action as it can increase contamination if tanks and lines are not properly cleared. Cargo tanks should be cleaned to the standard necessary to meet the requirements for the next cargo or, where applicable, for clean ballast or for tank-entry and repairs. The Tank Cleaning Table 4 is to be used as a guide to the degree of cleaning necessary between cargoes. Depending on the intended use of the product concerned, the standard of cleanliness required by some Charterers/Receivers may be different from that found within these guidelines. It is therefore extremely important to ensure that cleaning instructions are provided in writing. In crude oil carriers and black oil product carriers, periodic washing should be carried out to control sediment build-up. On crude oil ships this sediment control is achieved by crude oil washing some or all cargo tanks during cargo discharges as specified by MARPOL or more frequently depending on the cargo characteristics.

Inert gas The inert gas system, where fitted, should be operated appropriately during tank washing, gasfreeing and tank preparation operations. Additional safety precautions should be taken for vessels which do not have inert gas systems, although the tank washing recommendations provided in this document still apply. Safety recommendations contained in ISGOTT should be followed and in particular section 11.3.5.2 for non-inert washing. Prior to commencement of tank washing, and at maximum intervals of one hour, the oxygen level within each tank being washed should be verified as less than 8 % by volume at one metre below deck and at 50 % tank depth. Should the oxygen content exceed 8 % by volume at any time, tank washing should cease and the tank should be purged before washing may continue. In the event that vessels are gas-free for inspection, loading should not commence until all tanks have been re-inerted to below 8 % oxygen. Loading should never commence into tanks which do not contain inert gas
Static electricity Precautions to prevent static discharge during washing operations should be followed at all times. These are detailed in ISGOTT. Particularly hazardous conditions may exist when washing under non-inert conditions or when using hot water wash which can increase the temperature of cargo residues closer to their flash point.
17A.2
BOTTOM AND LINE FLUSHING
General It may be acceptable to flush the tank bottoms with the next grade to be loaded as an alternative to washing. This flushing medium is normally then discharged ashore or segregated on board. Discharges to shore can only take place after discussion with all parties involved. Flushing pumps and lines using water can only be considered when suitable reception facilities are available ashore or where washings can be pumped to a suitable slops tank. On completion, all lines and pumps should be well drained, but the practice of draining to the pump room bilge should be avoided
Fuel oil cargoes When changing from heavy to light grades, or from high to low sulphur, it may be possible, under certain circumstances, to reduce the tank preparation procedures. Tanks which are to receive the lighter grade should be very well drained, with a minimum ROB quantity. Provided that any contamination would not significantly alter the quality of the cargo to be loaded, then load on top may be possible. However, this matter should always be clarified with all interested parties and the cargo owners, the necessary calculations undertaken to check the effect on the quality of the subsequent cargo, and preparation procedures received in writing from the Installation Representative and/or Cargo Inspectors. Where uncertainty exists, the tank washing guidelines should be followed.

When loading vacuum gas oil/waxy distillate or other feedstock products, it will be necessary to 'fresh water rinse' any tank which has previously contained salt water ballast or has been cleaned using salt water (see Table 3).
17A.3
ELIMINATION OF WATER FOR CRITICAL CARGOES
When it is necessary to mop tanks dry for critical cargoes such as aviation kerosene or lubricating oil, care should be taken to achieve a compatible standard of preparation throughout that portion of the cargo system allocated to the critical product. The following procedures should be followed: •
The cargo lines which are to load and discharge the critical product should be opened and drained dry. This includes manifolds, drop line, pump discharge lines and tank suction lines.
•
Cargo pumps and their associated air vessels, strainers and by-passes should be opened and drained dry. This is to include any vacuum breakers.
•
Individual tank suction valves should be opened and remain open during the mopping process. Valve inspection covers should be opened as necessary.
•
Where fitted, fixed eductor systems should be blown through with air, valves opened and lines left to drain into the tank prior to mopping.
•
Fixed tank washing lines should be drained, and any water in the leg between the main line and the machine allowed to drain into the tank via the machine prior to mopping.
•
After draining, the fixed tank cleaning machines should be positively isolated from the supply line by blanking or other secure means.
Any list placed on the vessel to assist in draining and mopping should be removed before the tank is finally inspected. This will allow any water which may have collected on upper stringers/stiffeners, etc, to drain down. Particular attention should be paid to the inert gas deck seal overboard line. It should be ascertained that this line is free from blockage and that there are no valves partially or fully closed. Any substantial increase in the deck seal water level will cause 'carry over' and introduce water back into the tank during re-inerting. As a general rule when loading, the product should be directed initially into a single tank using as many lines as possible. This will ensure that any water trapped in the system will be flushed through to this single tank. The water is then much easier to deal with at the discharge port if necessary. However, this procedure should be verified with the charterers.
17A.4
DISPOSAL OF RESIDUES
Cargo residues Tank-washings and oily-ballast residues remaining on crude oil and black oil carriers should be retained on board. Crude oil carriers should load cargo on top of these residues, unless otherwise instructed by the Company or a Charterer. Black oil carriers should discharge the residues to shore reception facilities, when they are available, otherwise they should retain them on board, segregated from the cargo until such times as it is possible to either load on top or discharge to a shore facility.

OPS Document No. 017A Tank Cleaning Guidelines
Residues on white oil carriers can be dealt with in compliance with the MARPOL 73/78 Regulations to reduce the quantity of residues on board. When shore reception facilities are available at the loading port, residues should be discharged to the facilities. If they are not available, residues should be retained on board, segregated from the cargo.
Tank washing residues Scale and solid residues on the horizontal surfaces within a tank can contain volatile liquids and generate gas when disturbed. On crude oil carriers the build-up of sludge deposits can be controlled by effective crude oil washing. On other ships, routine water washing can be used. When sludge has to be physically removed from tanks, it shall not be disposed of overboard at sea but should be bagged and landed to shore reception facilities. In coated tanks scale should be minimal, unless significant coating breakdown occurs.
Engine room residues These are generally the by-product of engine room separators/purifiers and are normally stored in holding tanks within the engine room. Periodically it is necessary to empty these tanks, particularly on those vessels not equipped with the facility to burn such products. If shore reception facilities are not available, on black/crude oil vessels it is acceptable to discharge this residue to the cargo slop tanks where it may be subsequently discharged to shore or have cargo 'loaded on top', where voyage orders allow. On white oil vessels, this residue should not be discharged to tanks which may subsequently be loaded with clean oils, as the residues may affect the quality of the loaded cargo. It would however be acceptable to discharge the residue to the slop holding tank where fitted, provided this tank can be washed during subsequent discharge of these slops to shore facilities. Note: not all shore reception facilities will accept engine room residues due to their chemical content and these may have to be stored in segregated slop tanks until arrival at a suitable port. Whenever residues are transferred from the engine room to cargo system, such transfers should be recorded in accordance with MARPOL regulations, in both Machinery and Cargo Oil Record Books.
17A.5
TANK WASHING
After black oil cargoes These cargoes range from gas oils to heavy fuel oils and the degree of cleaning will vary considerably with the grade to be loaded and the grades previously carried. Products within this group are persistent oils and residues and should be handled in accordance with 17A.4. In the absence of specific cleaning instructions or advice of next cargoes, with the exception of the slop tank, cargo tanks should be cleaned on normal ballast passages to a standard suitable for any of the products within the ship's usual trading pattern. Inert gas systems should be operated to reduce oxygen and hydrocarbon gases levels in accordance with 17A.1 of these guidelines. Any slops generated should be disposed of in accordance with 17A.4. If the ship is re-loading at the discharge port, it may be possible to pump washings/ residues from tank cleaning operations to a shore facility. Otherwise the residues will be retained on board. Regardless of the medium used for washing (cargo or water) care should be taken to ensure that segregation is not compromised. Reproduced from HM 50.

Heavy fuel oils may leave residues on tank bottoms and structures at low temperatures and these can cause serious contamination of the lighter fuels and gas oils. Washing should be continued until the required degree of cleanliness is achieved. The bottom portion of the tank, together with any internal structure, may require particular attention, especially after carrying heavy or waxy fuel oils. Hot water should always be used when the nature of the cargo warrants it or when a special degree of cleaning is required. The temperature of any residues should be 15 °C above the pour point in order to achieve effective removal by tank washing. Scale formation is not usually heavy in ships which are employed solely on black oil trading, but where present it may be mixed with waxy deposits from fuel oils, which make it difficult to clean to the standard for gas oils and light fuel oils etc. If a build-up occurs special arrangements may need to be made to remove or reduce these deposits. The amount of washing required when changing from a black oil cargo to a white oil cargo cannot be defined precisely as it varies considerably and depends primarily on the length of time the vessel was in the black oil trade, the condition of the tank coating and the arrangement of the cleaning machines within the tanks. In the best of situations it might take a little as four hours per tank; however, under less than ideal circumstances it can take many, many times longer. It is particularly important to ensure that blind areas under structures are adequately washed. After the initial washing, the tank should be gas-freed and inspected to check on the effectiveness of the washing. One of the major causes of tanks not being washed properly is poor monitoring of machines. They are prone to sticking so that the nozzles fail to rotate in the vertical plane and the body fails to rotate in the horizontal plane. This results in the majority of the structure being washed only by splashing. Where washing with hot water has not been undertaken for some time, scale is likely to detach from the inside of the tank-washing main and collect in the neck of the tank-washing machine, preventing rotation. This can occur frequently at the start of a hot wash and ship's staff should have spare machines available for use.
After white oil cargoes White oil cargoes range from very light volatile oils like naphtha, to gas oils and lubricating oils. Good stern trim and efficient use of washing equipment are important. Minimum tank washing patterns should be used. The inert gas system, where fitted, should also be operated to reduce oxygen and hydrocarbon gas levels in accordance with 17A.1 of these guidelines. Any slops generated should be disposed of in accordance with section 17A.4. For coated tanks cold water washing is generally adequate for cleaning after most cargoes, except after the carriage of the heavier lubricating oils where hot water or detergent wash may be required. Also, the incompatibility of certain grades to one another may require the removal of all previous cargo (see Table 4). The use of hot water expedites tank cleaning and gas-freeing after the discharge of white oil cargoes. It removes oil films more quickly and, by raising the temperature of the tank atmosphere, promotes the release of gas trapped in scale and accelerates ventilation. Hot washing should be used when cleaning for dry-docking or repairs or when a special degree of cleanliness is required. Although it is often important to remove all traces of the last cargo it is equally important to avoid excess tank washing as this may eventually lead to expensive renewal of tank coatings.

that the coatings are in a good condition, adhesion of most types of clean oil is minimal and this reduces the amount of washing required. With volatile cargoes, little residue is left on tank sides and structure other than liquid and gases trapped in scale and other loose materials. With gas oils and lubricating oils an oily film will remain. With all cargoes, there is also a small amount of liquid left below the effective stripping level. Bottom washing and stripping should be continued until all oil residues are removed. Most white oil ships have coated or stainless steel cargo tanks and scale deposits will be minimal. Any accumulations of scale should be removed frequently, and excessive coating break-down leading to build-up of scale should be reported.
After crude oil cargoes The statutory requirements for washing after crude oils are contained within MARPOL for both segregated and dedicated ballast tankers. Additional sources of information are the vessel's Cargo Operations Manual and EI HM40. As with other cargo types noted above, inert gas should be operated to reduce oxygen and hydrocarbon gas levels in accordance with 17A.1 of these guidelines and any slops generated should be disposed of in accordance with section 17A.4. The following points should be assessed when considering the need for water washing of crude oil tanks: •
The build-up of sludge in the tanks
•
Wax content of the crude
•
The possibility of delaying the washing until the vessel is in warmer water
•
The use of portable machines
•
The next crude to be carried and its suitability for washing
After vegetable oil cargoes Vegetable oils can be defined as drying, non-drying and semi-drying. •
Non-drying oils are liquid at ambient temperatures and are easy to clean from surfaces using detergents and degreasers. Iodine values tend to be below 110 (examples are coconut oil, palm oil, palm kernel oil, olive oil).
•
Drying oils create solid residues which can form a hard skin at ambient temperatures. They are more difficult to remove from surfaces. Iodine values tend to be between 140 and 190 (examples are linseed oil, tung oil).
•
Semi-drying oils have iodine values between 110 and 140.
The drying properties (iodine value) are not related to the melting point so a light oil may well exhibit drying properties. Before loading any white oil cargo after the carriage of vegetable oils, clarification of cleaning procedures should be obtained from the charterer/receiver. There are many types of vegetable oil, some of which have chemical additives. Generally, efforts should be made to remove all traces of such cargoes before loading petroleum products, as vegetable oil traces may affect not only the next cargo but those following later.

Lighter vegetable oils will typically be cold water washed then washed with warm water and a degreaser or saponifier. Heavier types may require hot water washing, again with degreaser or saponifier, followed with a solvent wash. If the previous cargo was a drying oil then a hot wash with saponifier followed by additional water washes until the ph is neutral will be required. Cold water washing of each tank immediately after completion of discharge may avoid formation of a film on internal tank surfaces and should be carried out before warm or hot water washes which may cause oil films to dry ('varnish') unless cold water is used first. See also 17A.5 and 17A.12 regarding loading aviation kerosene cargoes after biologically derived products.
After FAME (Fatty Acid Methyl Esther) or blended biodiesel cargoes Recent analysis has shown that FAMEs adhere to surfaces more readily than other oils. However, as they remain liquid at ambient temperatures they can be cleaned using a water wash and saponifier as described in 17A.5 for lighter vegetable oils. Note: saponifiers should not be used to prepare tanks for aviation kerosene cargoes as residues can harm aviation fuel filters (see 17A.12). Contamination of aviation kerosene with FAME is a serious concern and current specifications permit only 5 ppm FAME in aviation kerosene (possibly to be increased to 100 ppm). Intermediate cargoes and a strict washing regime is therefore recommended when following these cargoes with aviation kerosene (see 17A.12). There have been no reported problems from these cargoes with odour or with softening or absorption into coatings.
After gasoline/ethanol blended cargoes For tank cleaning purposes these cargoes may be treated in the same way as the equivalent nonbiologically derived cargoes for non aviation fuel purposes. Where aviation products are involved, see Table 2.
Use of Chemicals Due to environmental considerations, tank cleaning chemicals should no longer be used except where there is a requirement for stringent cleaning in which case specific instructions should be issued for chemically-assisted cleaning at the time of the cargo nomination. Where chemicals are used slops should be segregated to allow for easier disposal.

Client/Charterer procedures.
The entire COW system should be tested to 1.5 times the working pressure at a suitable time prior to arrival.
Cleaning of sampling equipment and stilling wells The tight specifications for sensitive grades require extreme care during sampling, particularly closed or restricted sampling, to avoid contamination from previous cargoes or build-up of residues. Examples of this are FAME contamination of aviation fuels, and vegetable oils in gasolines. To reduce the possibility of drawing unrepresentative samples, the cleaning of sampling equipment, vapour locks, stand pipes and stilling wells is recommended as part of the tank cleaning regime.
17A.6
TANK INSPECTIONS
General Responsibility for the cleanliness and overall suitability of tanks, lines and pumps to carry the nominated grades lies with the Master. Inspections are frequently carried out by the loading supervisors from the shore facility or by independent inspectors acting on behalf of the cargo owner. However, while such inspections may provide an opinion regarding those tanks which have been inspected they do not relieve the Master of his/her responsibilities. Tank entry for inspections is potentially dangerous and should only be done under close scrutiny in accordance with a strict permit to enter/work system in gas-free tanks. Careful attention should be given to the need for lighting, access, safety equipment, personal protective equipment and the general tank environment e.g. residues on plates (slip hazard) etc.
Inerted tanks Any requirement for cargo tank(s) to be de-inerted and gas-freed to allow internal inspection should be contained within the agreed Charter Party or voyage orders for the voyage about to be undertaken as de-inerting/re-inerting is costly and time consuming. Reference should be made to ISGOTT recommendations with regard to inerting.
17A.7
HEATING COILS
Testing Heating coils should be pressure tested, and if necessary, blown through and repaired, on each occasion prior to: •
Loading a cargo which requires heating.
•
Carrying out tank repairs or tank entry (so that any coil leak will not introduce hydrocarbon gases or product into the tank).
•
Gas-freeing for voyage repairs or dry-docking.

Similar action should be taken when changing from a low flashpoint to a high flashpoint cargo or from black oil products to white oil products.
Heating coils made from copper-containing alloys Heating coils made from copper-containing alloys can reduce the thermal stability of aviation kerosene due to copper dissolving into the cargo from the alloy. Concentrations of copper in aviation kerosene fuel above 10 parts per billion (ppb) start to affect thermal stability and 50 ppb invariably results in failure to meet specified requirements. For this reason, aviation kerosene should not be carried in ships fitted with heating coils made from copper containing alloys.
17A.8
TANK COATINGS
Temperature restrictions In ships with coated tanks, the temperature and pressure of washing water should not normally exceed 66 °C and 10.5 kg/cm² respectively. However, these may be increased subject to the following criteria: •
Agreement from the coating manufacturer that excessive heat and/or pressure will not damage the coating.
•
Agreement from the tank cleaning equipment manufacturer that excessive heat or pressure will not cause damage to the machines.
The temperature of the washing water should always be at least 15 °C above the pour point of the previous cargo. In coated tanks of white oil carriers washing with cold water is generally adequate, except where more stringent cleaning is required after the carriage of vegetable oils, lubricating oils and diesel fuel. Hot water (and/or detergents) may be used occasionally to degrease tank structures, expedite gasfreeing for entry or where a gas-free condition is required for a major change of grade. When hot water is used this should be in accordance with the criteria noted above.
Coating compatibility Although not directly related to tank washing, it should be noted that tank coatings are not compatible with all products. Problems usually relate to chemicals rather than petroleum products but manufacturers' Resistance Lists (usually kept on board) should be consulted if there are any doubts regarding coating compatibility. Organic epoxy coatings can absorb some chemical cargoes, particularly chlorinated solvents. The contamination potential to subsequent cargoes (particularly aviation kerosene) may be considerable as significant quantities can be absorbed and retained depending on the chemical, exposure time, temperature, specific coating type, thickness, condition, etc. Contamination can persist after several subsequent cargoes and washings. For aviation fuels, many oil companies have their own list of acceptable coatings. Coatings containing zinc may not be suitable for the carriage of aviation fuels as zinc can dissolve into the cargo and can reduce the thermal stability. The charterer should be consulted regarding coating acceptability for aviation fuel cargoes. Reproduced from HM 50.

Stainless steel Although stainless steel is compatible with most grades it is subject to attack by chlorinated compounds. This is made worse by the presence of water. Also, some stainless steel grades are subject to attack by sea water so if a sea water wash is used in a stainless steel tank this should be followed immediately by a fresh water rinse. Note: some shore supplied 'fresh' water can contain sufficient chlorine to attack/ discolour stainless steel.
Coating condition Damaged, flaking or blistering paint can increase hold up of residues from previous cargoes and tanks with damaged coating should be avoided, particularly for critical cargoes such as naphthas, light distillate feedstock and aviation kerosene.
17A.9
CARGO LINES
General Procedures for line washing should be contained in the vessel's Cargo Operations Manual. Careful visual inspection of the actual pump room and above-deck piping configuration should be undertaken to identify any problem areas or 'dead ends' which will require special attention.
Cargo compatibility When loading more than one grade of cargo it should be determined whether the grades are compatible in both the liquid and vapour state. Compatibility between cargoes is entirely dependent on their essential characteristics and the quality specification of each grade. Permissible admixture of one cargo by another is governed by the tolerance of quality characteristics such as flashpoint, colour, sulphur content, viscosity, etc. Table 1 provides guidance for acceptability of pipeline admixture and the more detailed information in Tables 2 and 3 can also be used to assist in determining the pump/line changeover procedures required between cargoes during loading and discharging operations and to optimise the use of lines and pumps to expedite cargo handling. Liquid compatibility If the grades are not compatible each grade should be loaded through a separate system with segregation provided by two valves or a blind. Where different but compatible cargoes, such as two grades of crude, are loaded single valve segregation may be acceptable providing that the critical valves have been tested and proved tight. If two or more cargoes are compatible, loading should be carried out in sequence commencing with the most critical cargo. Any admixing which may occur will then not adversely affect the quality of the second cargo to be loaded and it will still meet the required specification requirements. Lines should be drained and/or stripped dry between grades.

Vapour Compatibility Vapours from a volatile cargo such as gasoline, can be taken up in diesel or gas oil cargoes which share the same vent systems, or are under the same positive pressure of inert gas. If vapour mixing can occur each cargo should be loaded on a separate cargo and vent system with vent system cross-over valves locked and tagged in the closed position. If it is not possible to load using separate vent systems then, when the ship design allows without impacting on SOLAS Chapter 2 – II Reg 2.5.3, individual tanks should be isolated from the system. Interconnecting inert gas block valves should be closed and tagged and if vapour contamination from slops is possible, slops should be isolated from the main inert gas line. The oxygen content of isolated slop tanks should be monitored to ensure that it remains less than 8 % by volume. Note: before any tank is isolated from the main venting system due consideration should be given to meeting the SOLAS requirements and a formal risk assessment should be conducted. The pressure in any tank segregated from the main venting system should be carefully monitored to ensure that individual tank venting arrangements are adequate to prevent formation of vacuum or a build-up of pressure.

The Table assumes that tanks are coated and in good condition. Where this is not the case additional cleaning may be required depending on the cargo involved, typically the addition of gas-freeing, descaling and mopping where wash only is specified. Stripping and draining following discharge or washing is assumed to be thorough such that any liquid ROB is confined to the pump well (if present). All associated lines (suction, deck lines, and drop lines, etc.) are to be cleared and drained of all product or water. Where washing is specified this includes deck lines, loading drop lines and cross over lines. The following of these guidelines does not necessarily mean that the tank(s) will be acceptable for the next intended cargo. The Master is ultimately responsible for the cleanliness of the tank(s) and should ensure that the end result meets the Owner's/Charterer's/Shipper's expectation.
17A.12 ADDITIONAL INFORMATION ON INDIVIDUAL CARGO TYPES Naphthas and light distillate feedstocks (and/or – clean condensate, feedstocks, straight run benzene, pentane, natural gasoline, straight run gasoline) Naphtha and light distillate feedstocks should not be contaminated by lead and should not be carried directly after cargoes that contained lead e.g. aviation gasoline. Tank coating should be in good condition as blistered or flaking tank coating can be a source of contamination from the previous cargo. Oxygenates can affect naphtha processing and washing is therefore required when loading naphtha into tanks which have previously contained unleaded gasoline cargoes. Sea water washing should be followed by a fresh water rinse to remove chlorides. Heavier feedstocks can tolerate minor admixing of aviation kerosene, kerosene, solvents or lighter feedstocks.
Aviation gasoline (and/or – avgas, aviation spirit) These products normally have a high lead content and are always dyed. Uncoated tanks should be hot water washed and have any loose bottom scale removed before loading. Water cannot be tolerated and extreme care should be taken to ensure that tanks and lines are dry before loading or discharging. Hand mopping is recommended. Detergents and saponifiers should not be used to prepare tanks for aviation gasoline cargoes as residues can harm fuel filters/coalescers. Ethanol/MTBE contamination of aviation gasoline could lead to specification issues. Thorough washing is required to ensure prevention of cross contamination and the proposed tank cleaning/flushing plan should be discussed and agreed with the Charterer. To avoid contamination from FAME it is recommended to have three intermediate cargoes with no FAME between FAME (B100) or any cargo with a FAME content greater than 15 % (B15) and an aviation gasoline cargo.

OPS Document No. 017A Tank Cleaning Guidelines
When following cargoes with a FAME content of 5 % or less (B5 or below) a hot water wash, including flushing of pumps and lines followed by draining is recommended as a minimum. When following cargoes with a FAME content of 15 % (B15) or less, but above B5, a hot water wash, including flushing of pumps and lines, followed by draining is again recommended as a minimum. However, tanks must be in good condition and washing needs to be particularly stringent. A single intermediate cargo with no FAME content is suggested as an alternative, followed by a hot water wash, including flushing of pumps and lines, and by draining. The very low tolerance for FAME contamination requires extreme care during sampling. To reduce the possibility of drawing unrepresentative samples, consideration should be given to cleaning of stand pipes and stilling wells as part of the tank cleaning regime when tanks have previously held cargoes containing FAME. Note: the recommendations relating to FAME also apply to FAEE.
Leaded motor gasoline (and/or – premium/regular motor spirit, motor gasoline, mogas) These products are often dyed and may contain surfactant additives. Only minimal amounts of higher boiling point cargoes such as gas oil can be tolerated in motor gasoline. Depending on the product specification up to 0,1 % volume may be tolerated. Where the product is close to specification limits a nil tolerance level will apply. Tanks will require washing when following cargoes of dyed gas oil or kerosene. Uncoated tanks should be hot water washed and have loose bottom scale removed before loading.
Unleaded motor gasoline (and/or – unleaded motor spirit, regular unleaded, premium unleaded, super unleaded, toluene, methyl tertiary butyl ether (MTBE), reformate, alkylate, cracked spirit, motor spirit/gasoline blending components) Thorough tank washing is required when following leaded products, dyed gas oil or kerosene. Uncoated tanks should be hot water washed and have any loose bottom scale removed before loading.
Ultra low sulphur gasolines In addition to the additional information in 17.12 these cargoes have a typical maximum sulphur content of 10 ppm (or possibly 50 ppm depending on location). If they are to be loaded into tanks or through lines that have previously contained cargoes that had a greater sulphur content care should be taken to ensure that admixing is kept to a minimum. These products are salt water critical as the high specifications will not allow sodium or potassium. Fresh water washing and mopping may be specified.
Solvents (and/or – special boiling point solvents, rubber solvent, unleaded cleaning spirit) These are volatile unleaded products.

Due to wide variations in specifications within grades specific guidance should be sought on the allowable levels of admixing with other solvents. No admixing with other types of product can be tolerated and these products should not be carried after leaded cargoes. Uncoated tanks should be hot water washed and have any loose bottom scale removed before loading.
Aviation kerosene (and/or – dual purpose kerosene, Jet, Jet-A1, Avtur, ATK, JP5, JP8) Products are unleaded and fairly volatile. Products may contain relatively high levels of sulphur which could affect the quality of a subsequent low sulphur cargo. Very tight specifications preclude admixing by other cargoes except undyed general purpose kerosenes with no biological components. Water cannot be tolerated and extreme care should be taken to ensure that tanks and lines are dry before loading or discharging. Hand mopping is recommended. Due to strict limitations on biological contamination (FAME content maximum 5 ppm, possibly increasing to 100 ppm) it is recommended to have three intermediate cargoes with no FAME between FAME (B100) or any cargo with a FAME content greater than 15 % (B15) and a subsequent aviation kerosene cargo. When following cargoes with a FAME content of 5 % or less (B5 or below) a hot water wash, including flushing of pumps and lines followed by draining is recommended as a minimum. When following cargoes with a FAME content of 15 % (B15) or less, but above B5, a hot water wash, including flushing of pumps and lines, followed by draining is again recommended as a minimum. However, tanks must be in good condition and washing needs to be particularly stringent. A single intermediate cargo with no FAME content is suggested as an alternative, followed by a hot water wash, including flushing of pumps and lines, and by draining. The very low tolerance for FAME contamination requires extreme care during sampling. To reduce the possibility of drawing unrepresentative samples, consideration should be given to cleaning of stand pipes and stilling wells as part of the tank cleaning regime when tanks have previously held cargoes containing FAME. Where the FAME content of a previous cargo is not known it should be assumed to be 15 %. Note: the recommendations relating to FAME also apply to FAEE. Other cargoes can have a deleterious effect on aviation kerosene product quality and intermediate cargoes are recommended in these circumstances (see Tables 2 and 4). Detergents and saponifiers should not be used to prepare tanks for aviation kerosene cargoes as residues can harm aviation fuel filters. In all cases a fresh water rinse is required after washing with sea water in order to reduce salt contamination.

Premium and regular kerosenes (and/or – kerosene feedstock, burning oil, stove oil) Products may contain relatively high levels of sulphur which could affect the quality of a subsequent low sulphur cargo. Admixing of dyed kerosene with un-dyed kerosenes can result in the un-dyed cargo not meeting colour specifications. Tanks which have carried dyed products will require washing and mopping dry prior to loading un-dyed products. Where dye is not a concern, these products will not require tanks to be mopped after water washing unless following lube oil or light fuel oil. Small amounts of gas oil may be tolerated (up to 0,1 % volume) subject to additional information under 17.12.
Gas oil and automotive diesel fuel (and/or – automotive gas oil, automotive diesel oil, DERV, extra light fuel oil, distillate marine diesel) Some admixing with lighter distillate cargoes such as kerosene is acceptable, depending on minimum flashpoint requirements for the individual cargo. However, flashpoint requirements will preclude admixing with any naphtha, motor gasoline or other cargoes with low flashpoints. Water contamination is a problem leading to 'haze' in' the product. This can produce a water layer and subsequent corrosion in downstream storage. Sodium in any dissolved salt can lead to damage to blades if the fuel is used for gas turbines. Care should therefore be taken to ensure that water is removed from tanks, pumps and lines before loading. Uncoated tanks should be hot water washed and have any loose bottom scale removed before loading. The admixing of dyed gas oil with un-dyed gas oil can result in the un-dyed material not meeting the colour specification and tanks which have carried dyed products will require washing prior to loading un-dyed products. Saponifiers and degreasers can have a negative effect on gas oil or automotive diesel fuel quality and if these are used hot water washing is recommended to remove any traces. Increasingly, diesel fuels for road transport are blends of FAME and conventional diesel fuel–blended biodiesel. These blends may simply be referred to as diesel fuel, but the grade name may indicate the percentage of FAME. Thus a B5 diesel fuel contains 5 % FAME and B15 diesel fuel, 15 % FAME. Cleaning procedures vary with the percentage of FAME in the blend so it is important that shippers determine the FAME content of diesel fuel cargoes. Where the FAME content of a diesel fuel cargo is not known it should be assumed to be 15 %. Note: these comments also apply to FAEE.
Ultra low sulphur automotive diesel fuel (and/or – ULSD, ULS turbine gas oil, LS marine gas oil, ULS Diesel) In addition to the information in 17A.12 these cargoes typically have a typical maximum sulphur content of 10 ppm (possibly 50 ppm depending on location). If they are to be loaded into tanks or through lines that have previously contained cargoes that had a greater sulphur specification care should be taken to ensure that admixing is kept to a minimum.

These products are salt water critical as the high specifications will not allow sodium or potassium. Fresh water washing and mopping may be specified.
Crude oil and condensate The specifications of these cargoes vary considerably. General guidance together with a list of physical properties of many grades together with washing and carriage recommendations is given in HM40 Guidelines for the crude oil washing of ships' tanks and the heating of crude oil being transported by sea.
Lubricating oils The quality of lubricating oils is greatly affected by admixing with water and tank preparation will normally include mopping. Valves and strainers will also require opening and draining. To maintain quality and avoid introduction of water, lubricating oils should be loaded, carried and discharged under air and not inert gas.
Vacuum gas oil (and/or – cracker feed, waxy distillate) These cargoes are sodium critical and tanks which have been salt water washed will require fresh water washing to remove any salt traces. Vacuum gas oil may be loaded on top of some light crude oils and condensates without washing. However, as with fuel oils, the need to heat the product leads to a high flashpoint specification and precludes admixing with any volatile residues.
Medium and heavy fuel oils The admixing of these cargoes with waxy residues can result in the material not meeting the maximum pour point specification limit. Tanks which have carried high pour point cargoes should be carefully drained and stripped prior to loading. The need to heat the product leads to a high flashpoint specification and precludes admixing with any volatile residues. Washing will generally be required when loading these products after crude oil cargoes.
Low sulphur fuel oil (and/or – Low Sulphur Atmospheric Residue (LSAR), Low Sulphur Waxy Residue (LSWR)) In addition to information in 17A.12, these products are frequently traded with sulphur content very close to the specified upper limit. Admixing with cargoes with higher sulphur content should therefore be kept to a minimum. Hot washing will normally be required when loading after crude oils or other fuel oils. Cargoes for refinery cracking will also be sodium critical and tanks which have been salt water washed will require washing with fresh water to remove any salt traces.
Light fuel oil The admixing of these cargoes with waxy residues can result in the material not meeting the maximum viscosity and/or pour point specification limit. Tanks which have carried high pour point or high viscosity fuel oil or crude oil should be hot washed at the highest permitted temperature to remove wax traces. Reproduced from HM 50.

Washing may be avoided if a previous cargo of heavier grade fuel oil has low wax content and ROB is minimal (less than 0.1 % of volume).
Gas to Liquids (GTL) products A number of these are entering the market; typically naphtha, condensate and diesel. Properties are as per similar non-GTL cargoes but all are ultra low sulphur and should be handled accordingly.

Table 2 Notes: Flash Point
In order to meet flash point specification for all medium/high flash cargoes it is critical that tank and line admixing with low flash cargoes is rigorously avoided.
Lead
Certain cargoes require that precautions are taken to avoid admixing with previous leaded cargoes. However tanks that have contained leaded cargoes may be used providing that tanks are thoroughly cleaned. Tanks which have previously contained leaded cargoes should not be used for solvents (SBPs) or white spirit as these product can be used in food manufacture (lead free below 50 ppb : Japan-two previous lead free cargoes). To minimize tank cleaning it is recommended that a minimum number of tanks on each vessel should be used for leaded cargoes, the remainder being kept lead free.
Water
Drain pipelines/pumps and mop up water in tanks prior to loading water critical grades. As far as possible maintain separate lines and pumps for these grades and avoid using these to pump water for shore purposes.
Colour
Colour critical grades should be stowed in tanks which have previously held colourless grades
Octane number
Unavoidable pipeline mixing between aviation gasoline or motor gasoline cargoes should be from a higher to a lower octane number cargo.
Hydrogen Sulphide and mercaptans
When present in sufficient quantities these make a cargo ‘sour’ and are frequently found in naphthas and natural gasolines as well as crudes and fuel oils.
Odour
Solvents (SBPs) are odour critical, which is a consideration after gas oil cargoes. Odour contamination via common vapour lines should be considered.
Vapour pressure
Many white oil grades have a high vapour pressure and details should be obtained at the load port with a view to appropriate handling at discharge.

Table 3 Notes: Flash Point
In order to meet flash point specification for all medium/high flash cargoes it is critical that tank and line admixing with low flash cargoes is rigorously avoided.
Colour
Machine washing with hot water is normally adequate for the colour critical grades after black oils. However, if tanks have carried black oil grades for a number of consecutive voyages additional cleaning including removal of deposits and flushing tanks and pipe with a suitable wash oil may be necessary.
Water
The majority of black oils do not require extensive precautions such as mopping tank dry. However water contamination (and particularly salt water contamination) should be avoided where possible so tanks used for ballast and associated pipelines should be well drained before loading. Bitumen and naphthenic distillates are exceptions and every care should be taken to ensure dryness of tanks, lines, and pumps. Vacuum gas oil cargoes will need salt water free stowage and tanks and lines should be fresh water rinsed.
Viscosity
Cargoes with high viscosity (>650cS at 50ºC) may have a detrimental effect on lighter products.
Metals and Asphaltenes
All cargoes in the waxy distillate/slack wax range are sensitive to these contaminants which are present in sea water, scale and residues from other grades. Thoroughly cleaning and draining is necessary prior to loading

18.1
OPERATION OF INERT GAS SYSTEMS
Crude Oil Tankers and Product Tankers th
The requirements of ISGOTT 5 Edition chapter 7.1 (fixed inert gas system) must be strictly adhered to at all times. All crude oil and product tankers using an inert gas system should maintain their cargo tanks in a non-flammable condition at all times. It is required for the Vessels to be inerted regardless of cargo. Tanks should be kept in an inert condition at all times, except when it is necessary for them to be gas free for inspection or work, i.e. the oxygen content should be not more than 8% by volume and the atmosphere should be maintained at a positive pressure. The atmosphere within the tank should make the transition from the inert condition to the gas free condition without passing through the flammable condition In order to maintain cargo tanks in a non-flammable condition the inert gas plant will be required to: •
Inert empty cargo tanks
•
Be in operation during cargo discharge, deballasting of cargo tanks, COW and water washing
•
Purge tanks prior to gas freeing
•
Top up the pressure in the cargo tanks when necessary during other stages of the voyage
Detailed records of all inert gas system operations and records of tank atmosphere readings must be maintained during inerting of tanks, during discharge or cow, during purging prior to gas freeing and for inert gas topping up operations.
Product Tankers The basic principles of inerting are exactly the same on product carriers as on crude carriers. There are, however, some differences in operational detail, as follows:

OMD Document No. 018 Inert Gas Systems
Carriage of Products Having a Flashpoint Exceeding 60ºC The 1974 SOLAS Convention, as amended, implies that tankers may carry petroleum products having a flashpoint exceeding 60ºC (i.e. bitumens, lubricating oils, heavy fuel oils, high flashpoint jet fuels and some diesel fuels, gas oils and special boiling point liquids) without inert gas systems having to be fitted or, if fitted, without tanks containing such cargoes having to be kept in the inert condition. However, when cargoes with a flashpoint exceeding 60ºC are carried at a cargo temperature higher than their flashpoint less 5ºC, the tanks should be maintained in an inert condition because of the danger that a flammable condition may occur. It is recommended that, if inert gas systems are fitted, cargo tanks are maintained in an inert condition whenever there is a possibility that the ullage space atmosphere could be within the flammable range. When a non-volatile cargo is carried in a tank that has not been previously gas freed, the tank should be maintained in an inert condition. Gas freeing is required on product carriers more frequently than on crude carriers, because of the greater need both for tank entry and inspection, especially in port, and for venting the vapours of previous cargoes. On inerted product carriers, any gas freeing operation has to be preceded by a purging operation. It should be recognised, however, that purging is not essential before gas freeing on a product tanker when the hydrocarbon gas content of a tank is already below 2% by volume. Before the vessel inerts the tanks again, prior to arrival at the new load port, the Captain should consult Thome and the local agent to establish whether in tank inspection during the pre-loading survey will be required, and the vessel should only arrive inerted if charterer accepts visual on deck inspection only. (Check Charter Party and /or Loading Instruction and/ or with Vessel's Operators) In case the inert gas system is not in operation on product tankers then detailed records of tank atmospheres must be maintained throughout all cargo and tank cleaning operations.
Operation of Inert Gas Plant Inert gas systems are maintained in continuous operation during discharging operations. In case if there are any instructions from Charterers or any other third party requests non use of IGS, the Vessel needs to confirm with the Thome Office, prior agreeing to such operations. Although there are differing designs of inert gas plants within the fleet, the procedures for staring up, shutting down and testing for safety are similar and are given below:Start-Up Procedures •
Ensure that the portable oxygen analyser, fixed oxygen analyser and recorder and inert gas pressure indicator and recorder are working correctly and correctly calibrated
•
Oxygen and pressure recorders must be used and the record charts identified by date and type of operation every time the inert gas plant is used
•
Ensure the boiler or inert gas generator is producing flue gas with an oxygen content of note more than 5% by volume in the inert gas supply main to the cargo tanks
•
Ensure that power is available for all control, alarm and automatic shutdown operations

•
Check the water level in water loops installed in pipe work for gas, water or pressure transducers, to prevent the back flow of hydrocarbon gases into gas safe places
•
In cold weather, ensure that the arrangements to prevent the freezing of sealing water in the deck seals and pressure vacuum breakers are in order
•
Check the IG pressure and record in the deck log book once per watch. Before the pressure in the inerted cargo tanks drops to 100 millimetres of water these tanks are to be re-pressurised
Possible Failures and Action to be taken High oxygen content which may be caused or indicated by the following conditions: •
Poor combustion control at the boiler, especially under low load conditions
•
Drawing air down the uptake when the boiler gas output is less than the I.G. blower demands, especially under low load conditions
•
Air leaks between the inert gas blower and the boiler uptake
•
Faulty operation or calibration of the oxygen analyser
•
Inert gas plant operating in the re-circulation mode, or entry of air into the inert gas main through the pressure vacuum valves or mast risers due to incorrect operation
•
If the inert gas plant is delivering inert gas with an oxygen content of more than 8% then all cargo tank operations are to be stopped, and the fault is to be traced and repaired. All crude oil washing and water washing of tanks is to be stopped
The inability to maintain pressure during cargo discharge or deballasting operations may be caused by: •
Inadvertent closure of the inert gas valves
•
Faulty operation of the automatic pressure control system
•
Inadequate blower pressure, or a cargo rate in excess of the blower output
The cargo discharging or deballasting is to be stopped or reduced depending on whether or not positive pressure in the tanks can be maintained while the fault is rectified. If positive pressure cannot be maintained all cargo tank operations must be stopped.
Carriage of Cargoes under Inerted Conditions Tankers using an inert gas system should maintain their cargo tanks in a non-flammable condition at all times. It follows that: •
Tanks should be kept in an inert condition at all times, except when it is necessary for them to be gas free for inspection or work, i.e. the oxygen content should be not more than 8% by volume and the atmosphere should be maintained at minimum of 100 mm wg pressure.
•
The atmosphere within the tank should make the transition from the inert condition to the gas free condition without passing through the flammable condition. In practice, this means that, before any tank is gas freed, it should be

purged with inert gas until the hydrocarbon content of the tank atmosphere is below the critical dilution line (line GA in ISGOTT Figure 1.1). •
When a ship is in a gas free condition before arrival at a loading port, the tanks must be inerted prior to loading.
•
Once Inerted the cargo tanks should be checked daily to confirm that the oxygen content is not more than 8% by volume and the atmosphere is being maintained at minimum of 100 mm wg pressure.
During Loading Operations •
During the pre - Loading checks, the flame screen of mast riser or equivalent venting arrangements should be inspected to confirm the condition & replace as necessary
•
When loading cargo the deck isolation valve should be closed and the inert gas plant is to be shut down unless otherwise stated.
•
All openings to cargo tanks, except the connections to mast riser or equivalent venting arrangements should be kept closed to minimize flammable vapors on deck.
•
All I.G. inlet valves to individual tanks should be open and handles locked, keys returned to C.C.R.
•

If individual tank IG supply valves are closed for reasons of potential vapour contamination or de-pressurization for gauging etc, then the status of the valve should be clearly indicated to all those involved in cargo operations. Each individual tank IG valve should be fitted with a locking device under the control of a Chief Officer.
•
All personnel in charge of cargo operations are aware that, in the case of failure of the inert gas plant, discharge operations should cease and the terminal be advised
•
During Loading or discharge operations, following parameters should be maintained o
Oxygen Content at delivery < 5%
o
Oxygen content in Cargo Tanks < 8%
o
Inert Gas pressure in Cargo Tanks > 200 mm wg

The Form is to be completed for each Cargo Operations, Tank cleaning / Purging and Gas freeing operations requiring the use of inert gas system including the topping up of Inert Gas during the voyage.
•
Although the % O2 in Supply, Press WG is required to be monitored continuously by the Duty Officer, it should be logged on commencement, at least every hour thereof.
INERT GAS EMERGENCY PROCEDURES
In the event of inert gas system failure, namely: •
inability to deliver the required quantity and quality of inert gas
•
inability to keep up pressure in the cargo tanks
•
shut down of the inert gas plant
Immediate action must be taken to prevent any air being drawn into the tanks. All discharging, deballasting, tank washing, ullaging or sampling must cease and the inert gas deck isolating valve must be closed. Cargo operations, as above, must not be recommenced until the inert gas plant is returned to service and tanks are satisfactorily inerted. During re-inerting; no ullaging, dipping, sampling or other equipment should be inserted into the tank, until it is established that the tank is inert. This should be done by monitoring the effluent gas from the tank being inerted until the oxygen content is reduced to less than 8% by volume and always provided that it is known that the effluent gas is fully representative of the atmosphere within the tank. Before introducing a gas sampling tube into the tank for this purpose, there should be a delay of 30 minutes following the cessation of inert gas injection. Metallic components of the sampling system should be securely bonded to earth, and should remain so for 5 hours after cessation of inert gas injection. Introduction of any other equipment into the tank after re-inerting must be strictly avoided. However, if such introduction is essential for the safety of the operation, it should be done only after at least 30 minutes have elapsed since the injection of gas has ceased, all metal components of the equipment CONTROLLED

must be securely bonded to earth and only natural fibre rope should be used for suspending the equipment. Again, these restrictions should be applied until a period of five hours has elapsed since the injection of inert gas has ceased. The above procedures are necessary for two reasons, namely static electricity and pyrophoric ignition.
Static Electricity •
th
Refer to ISGOTT 5 Edition
Pyrophoric Ignition •
18.3
Pyrophoric iron sulphide deposits, formed when hydrogen sulphide gas reacts with rusted surfaces in the absence of oxygen, may be present in the cargo tanks and these deposits can heat to incandescent when coming into contact with air. Therefore, in the case of tankers engaged in the carriage of crude oil, the failed inert gas system must be repaired and restarted, or an alternative source of inert gas provided, before discharge of cargo or ballast is resumed. Air must be excluded from the tank.
INERT GAS - MAINTENANCE AND INSPECTION
The safety arrangements are an integral part of the inert gas system and it is essential for the ship's staff to give special attention to them during any inspection. All maintenance and inspections contained this matter shall be recorded in the Inert Gas Record Book or in the PMS System. •

th
o
On ships with central air conditioning units, it is essential that the accommodation is kept under positive pressure to prevent the entry of hydrocarbon vapours. Intakes for air conditioning units are usually positioned in a safe area and vapours will not be drawn into the accommodation under normal conditions. A positive pressure will be maintained only if the air conditioning system is operating with its air intakes open and if all access doors are kept closed, except for momentary entry or exit. The system should not be operated with the intakes fully closed, that is in 100% recirculation mode, because the operation of extraction fans in galley and sanitary spaces will reduce the atmospheric pressure in the accommodation to less than that of the ambient pressure outside. There is a benefit from having a gas detection and/or alarm system fitted to air conditioning intakes. In the event that hydrocarbon vapours are present at the inlets, the ventilation system should be shut down and transfer of cargo suspended until such time as the surrounding atmosphere is free of hydrocarbon vapours. The same principles of positive pressure and gas detection apply to ships that have alternative air conditioning systems or where additional units have been fitted. The overriding consideration in all cases is that hydrocarbon vapours must not be permitted to enter the accommodation. Externally located air conditioning units, such as window or split air conditioning types, should not be operated during any of the operations listed in Section 24.1 (ISGOTT 5th ed) unless they are either located in safe areas or are certified as safe for use in the presence of flammable vapours. On ships that depend on natural ventilation, ventilators should be kept trimmed to prevent the entry of petroleum gas. If ventilators are located so that petroleum gas can enter regardless of the direction in which they are trimmed, they should be covered, plugged or closed.

SHIP-TO-SHIP TRANSFERS
Master to ensure that the SHIP to Ship Transfer operations plan as required by IMO Resolution MEPC.186 (59) and Chapter 8 Regulation 41 of Annex 1, MARPOL 73/78 is on board and same is consulted prior any STS being performed. A ship-to-ship transfer operation should be under the advisory control of a designated Person in Overall Advisory Control (POAC). The POAC will either be one of the Masters of the Vessels concerned or an STS Superintendent, Lightering Coordinator or Mooring Master employed by an STS Resource Provider. It is the responsibility of the Master to ensure that the Plan is current and that the STS operations are conducted in accordance to the requirements described on this Plan, ICS / OCIMF Ship to Ship transfer Guide – Petroleum and ISGOTT, as well as to maintain relevant records as required by the plan. Both ship’s Masters are responsible for respective operations, in spite that one of them may be agreed to be in overall advisory control of the operation (POAC). Each must satisfy himself that procedures reflect safe practice. Even in case an STS Superintendent is employed, the Master retains his overall responsibility for the safety of the ship and its crew. Thome Ship Management Pte Ltd (TSM) has a policy that all STS transfers MUST be conducted per the ICS / OCIMF Ship-to-Ship Transfer Guide. Masters shall notify Thome of forthcoming ship-to-ship (STS) transfer operations, once known, giving the following details: •
Expected date operations expected to take place.
•
Location where STS operations will take place and name of other ship.
•
Details of cargo to be transferred.

Master to confirm a full review of the plan has been done and all aspects are covered prior conducting the STS.
It should be noted that TSM strongly discourages STS berthing operations during the hours of darkness due to safety reasons, however if situation demands then this has to be further discussed with Senior Manager, Marine Standards & Vetting. ***The vessel must follow the below procedures prior / during STS operations*** Phase 1: Pre-Arrival Planning: The Pre-Arrival Planning should be carried out before any STS operations commence. The planning of the STS operation could be performed by the ships operators and managers together. Checklist 1 should be completed during this phase of the operation. Phase 2: Arrival: During the Arrival stage of the operation the two ships conducting the STS operation should establish radio communication, and concur that all operational procedures has been assessed and agreed upon. Check list 2, 3 should be completed during this phase of the operation. Phase 3: Berthing: The Berthing phase of the STS operation consists of the manoeuvring and mooring of the two ships. For the manoeuvring operation a contingency plan should be in place to deal with any emergency situation. Phase 4: Cargo Transfer: The Cargo transfer phase should only commence once the two ships are securely moored. The Master should ensure that all the recommended safety procedures in this plan are followed. A contingency plan should be in place to deal with any emergency situations during cargo transfer. Check list 4 should be completed before cargo transfer commences. Phase 5: Departure: Departure is the last phase of the STS operation. Checklist 5 should be completed before unmooring. TSM reserves the right to request our principles to refuse an STS operation if they deem it unsafe as a result of: a) Unsuitable lightering vessel nominated for the operation. b) Inadequate facilities, permissions or equipment to conduct a safe STS transfer.

CERTIFICATES
Renewal The Master is to ensure that the vessel has all the necessary certificates for the intended trading pattern and that they are valid. Before a certificate expires, renewal must be applied for in ample time. The Master shall keep a separate file for the vessel's "Trading Certificates" with a list of the contents showing issuing date and validity (File Index 4.1). Any recommendations or conditions of class (CoC) and condition of authorization (CA) issued in connection with renewal, annual or intermediate surveys are to be complied with, immediately, and Thome is to be advised of their imposition and correction.
Class and Statutory Surveys Separate files shall be maintained for class status reports, surveys reports and correspondence with the Flag State. See File No 4.2 5.1 and 5.2. Specific attention is drawn to the Liberian Flag State Annual Safety Inspection. On Liberian Flagged vessels, the Master must ensure that the annual safety inspection is carried out as per Liberian Maritime Regulation 7.191 (ref.: RLM-300). The Master is to ensure that class and statutory surveys are carried out within the due dates. The Master is to coordinate this with the Technical Superintendent and Fleet Group Manager. The Technical Superintendent and Fleet Group Manager are to be advised immediately of any defects, deficiencies and damages affecting class or a certificate. All Conditions of Class as issued by the attending Classification Society Surveyor is to be reported immediately to the office by Email with a copy of the CoC. Further notification is to be carried out via Ocean Manager in the Ship-Shore Reporting Section under Technical Deficiency and Observation Master List.
Notification of Expiry Dates On the date which a class certificate expires, (windows taken into consideration) classification of the ship and all other class certificates will be suspended automatically. The result of this is that the ship's insurance cover will become invalid. Therefore, the Master is to regularly review the certificate situation with the Chief Engineer and within the Sunday Technical Report advise of any certificate which are due to expire within the next eight (8) weeks.

22.1
CARGO GEAR REGISTER •
All cargo gear must be entered in the cargo gear register. This includes al loose gear such as hooks, blocks, chains etc.
•
The cargo gear register must contain a “rigging plan” that lists where all lose gear is being used, i.e. which blocks, hooks, swivels etc. are being used with which crane etc.
•
All lifting gear must be certified and the certificate must be on file, ready for inspection when required. The certificate lists the identification mark on each item of gear.
•
Annual examinations must be done at least every 12 months. A competent person such as Master, Chief Engineer or Chief Officer can do this provided the certificate of class does not have notation referring to the cranes. It is recommended that this be done at the time of annual surveys ad the attending surveyor should be asked to stamp the cargo register.
•
Every 5 years the cargo gear must be load tested and this must be recorded in the cargo gear register. This can only be done by Class surveyor. Some confusion occurs at this point as the proof loads required for loose gear is greater than that of the crane. However, if the block, hook etc is permanently attached to the crane, it is not considered as loose gear.
•
Every 5 years, all loose gear must be tested and thoroughly examined by Class. According to Class, thorough examination may be sufficient and testing is at the attending surveyor’s discretion. Hence, it is possible that after thorough examination, he will not require further testing, or testing of one set of gear or testing of all loose gear. However, this is not acceptable under Australian Marine orders. Therefore, during docking the master and superintendent should take the opportunity to test all loose gear to avoid the possibility of future problems that could prove costly.

ASPHALT TANKER OPERATIONS Purpose To specify procedures of asphalt tanker operations These Guidelines to be read in conjunction with the Bitumen Safety Code (Institute of Petroleum)
Application Asphalt Tankers
Responsibility Master Chief Officer Chief Engineer Deck Officers
24.1
ASPHALT CARGOES
The bitumen or Asphalt (Roofer's Flux) is sometimes also known as Tar in some countries. The main use of this compound is for building roads and water proofing. Asphalt (or bitumen) is obtained from petroleum by distillation, and is principally used as paving material. It has a specific gravity range between 1.00 to 1.04 and average volatility. The main characteristic of this compound is the high loading, carriage and discharge temperature. Loading temperature is normally about 140 degrees C, carriage about 150 deg and discharge temperature 150-160 deg C. These high temperatures are necessary for the cargo to flow. Precautions are necessary to keep the cargo in liquid state. For this reason heating system has to be in good order. Due to the high temperature of 150 deg C and above, steam is not suitable as heating media. Therefore thermal oil is used as the heating media. Asphalt is typically maintained in a temperature range of 110 deg C to 180 deg C and heated in such a fashion so as not to allow wide temperature swings in the range. To maintain this high temperature range the tanks have typically hot oil (thermal) heating coils. In addition to normal Tank Vessel Operations the following Safety Issues must be considered for Asphalt Storage: •
Condensation in empty tanks is extremely dangerous. Dangerous steam can be created when hot liquid Asphalt is introduced into a tank that has been empty for a while and accumulated moisture from condensation. o
•
CONTROLLED
To circumvent this, cargo tanks should be pre-heated prior to arrival at load port.
Extreme caution should be exercised when loading, unloading and sampling, due to the high temperatures involved. Failure of cargo tank insulation may Revision: 01 Apr 2012 Approved by DPA/DMR Page 1 of 6
THOME SHIP MANAGEMENT PTE LTD
OMD Document No. 024 Asphalt Tanker Operations
create some hot spots on the vessels weather deck and direct contact of hot surfaces can cause severe burns e.g. handling manual tank valves etc. o •
Protective equipment should be made available and used by all personnel involved in cargo operations.
Use Catwalks, screens, Barrier Guards and Shields to protect from Steam, hot Asphalt or other hot surfaces.
Due to the nature of its weight, the Permissible Load Density of the cargo tanks must be checked prior to finalizing cargo intake or Load plan.
24.2
HEATING OF CARGO
This is accomplished by circulating thermal oil from a heater into the cargo tanks via heating coils. Prior to commencing heating operations, the following checks should be carried out: •
Air in expansion tank is properly purged and bled-off and oil is not in contact with air.
•
There is enough oil in the reserve tank
•
Check that oil level in the expansion tank is at the correct level
•
Cooling-water levels (if required) for circulating pump checked
During operation of the heating system the temperature difference between thermal heater inlet and outlet temperature should, ideally, be 25 to 50 deg C. Thermal oil takes a long time to cool down especially when the load temperature is high. Keep circulating pump in operation for approx 30 minutes so as to gradually bring down the oil temperature. Operational checks to be done on daily basis during transit of cargo: •
Check that oil level in the expansion tank is at the correct level
•
Check the thermal valves for normal operation
•
Check for thermal oil leaks in the system
Annual inspection and testing of thermal oil is recommended If temp difference between the inlet and outlet is more than 50 deg C or if differential pressure is more than 4kg/cm, then adjust load bypass valve accordingly. Heating of asphalt cargoes should be brought up ideally not exceeding 30 deg C in a period of 96 hrs. However, not less than 54 hrs should be taken to bring cargo temp up to 180 deg C. Storage temperatures in the range of 100 to 130 deg C are particularly troublesome, and therefore not be allowed to cycle above and below the boiling point of water. Clear Heating Instructions must be obtained from Charterer and Master and followed accordingly.

CARGO OPERATIONS
Prior Loading Inspect the cargo tanks prior loading for any damage to insulation. The cargo tanks must be pre heated to min 100 Deg C. This will take around 18-24 hrs. Also cargo lines must be preheated prior to loading to melt away any cargo that may still be present in the pipelines. Prior full operation of the valves, the lines must be heated. If solidified Asphalt is present in the line adjacent to the valves, the valves spindles can break. Therefore in order to exert minimum force on the valve it is necessary that the cargo in the pipeline is melted. The heating should be gradual to keep thermal stresses to minimum.
Loading Upon Completion of cargo operation ensure to blow the lines, at least 4-5 times, from crossover connection at manifold, from port and starboard manifold. Open loading is considered safe and is acceptable in most of the ports. However prior sailing, ensure that all tank openings are fully shut. Any water Ingress will cause serious problem. As far as possible the cargo in the tanks should be loaded fall or kept empty. This is necessary for stability and also to avoid sloshing and damage to insulation. It is imperative that cargo temperature is monitored during loading and the minimum cargo temperature should be as stipulated in CP, if cargo temp is less than as defined in CP, the Owners and Charterer's must be notified, LOP Issued to terminal, all delays to terminal account to raise the temp and v/1 will be on demurrage (time will not be counted as lay time)
During Voyage During carriage the cargo temperatures must not be allowed to drop below 140 deg C or other special instructions of the shippers. Prior arrival discharge port (18 hrs), heat lines, pumps and operate valve to ensure proper functioning. COP must be manually turned after heating, prior arrival discharge port.
Discharge It is prudent to plan discharging and ballasting in such a way so as to avoid taking ballast in the side tanks. (Adjacent COT) Initially upon starting you might circulate the cargo via manifold cross over and drop lines just to ensure that the lines are clear. The discharge pressure on the system may rise very fast if there is any blockage in the line. Cargo will continue to flow to the suctions. Therefore one tank may have to be stripped many times. On completion of discharge the COP should be run dry at low rpm to clear the cargo from pumps and vertical lines in pump room. And all lines should be thoroughly blown from port, starboard and manifold crossover. Never allow excess pressure on the valves to prevent breaking of spindles. CONTROLLED

ANCHORS AND ANCHORING Purpose To specify requirements for the safe and efficient mooring of vessels and maintenance of ropes.
Application All vessels
Responsibility Master Navigating Officers Watch-keepers
25.1
READINESS OF ANCHORS
When vessel is approaching a port and after a competent seafarer has checked that the anchor brakes are securely on, the lashings shall be removed, both spurling and hawse pipes cleared. The anchor stopper bar to be kept engaged until such time that the vessel enters it’s maximum anchoring depth based on the calculations as under section 25.11 and as laid down in section 7.4 of the OCIMF publication “Anchoring system and procedures for Large Tankers”. Same shall be recorded in the Deck Log Book.
25.2
GENERAL REQUIREMENTS
All deck Officers must fully understand the operation of the windlass and brake assembly, this is not always obvious and may entail study of the manufacturer’s instruction manuals. Before using the windlass, thoroughly check the braking systems with special attention to: •
The remaining thickness of the brake lining
•
The amount of “take up” left on the brake operating spindle with the brake screwed hard up
•
The proper greasing of the brake linkage and the free movement of the various pivot points
All personnel involved in anchoring should be wearing the appropriate Personal Protective equipment. These should also include enclosed type goggles. (Ref: Code of Safe Working Practices for Merchant Seaman) Master shall ensure that anchor handling is supervised by a licensed Deck Officer. In addition, the bosun and one AB shall also be assigned to Anchor stations. Prior anchoring a check should be made that no small crafts or other obstacle is under the bow. Prior approaching anchorage position, Master shall ensure checks as per Anchoring Checklist is carried out (OMD Checklist No. 009).

ANCHORING – GENERIC
Preferably approach selected anchorage and anchoring position against resultant of prevailing wind, tide and current. Reduce speed, in due time before let go, so that anchoring position is reached with vessel maintaining steerage way stemming resultant. Use engines as required to prevent undue cable tension. Except in emergency situations, never let go anchors until vessel speed over ground is near zero. After letting go, vessel should be properly manoeuvred in order to carefully pay out necessary length of cable. Master shall be kept advised on amount of cable paid out, direction and degree of tension. To ensure against anchor dragging sufficient length of cable shall be paid out, taking into consideration prevailing and anticipated weather, tide, current and draught conditions. Minimum amount of cable should be six times depth of water at anchor let go position. Master may use more cable length whenever he considers it necessary to do so. Secure cable on windlass brake. After anchoring lower guillotine bar into position over anchor cable. The Officer of the watch shall take a number of bearings as soon as vessel has been brought up into riding position. These should be identified on the chart for additional position fixing. Subsequent check bearings should be taken frequently (e.g. at least once every hour) however the frequency of taking observations may change when taking into consideration prevailing environmental conditions. Anchor bearings/position shall be recorded in the Anchor Position Checks Record. As far as possible Port and Starboard anchors shall be used alternatively. The record of anchor used shall be recorded in the Deck Log Book Anchor chains, shackles, and pins shall be inspected whenever anchors are being weighed.
25.4
ANCHORING – SPECIFIC
Small and Medium Size Vessels For anchoring small and medium size vessels (under 65,000 DWT) in shallow water (below 40 meters depth), the anchor should be walked out to the water, disengage the windlass clutch, holding the anchor on the brake. When the vessel is in position and the vessel nearly stopped the anchor is “let go” and the chain paid out, controlled by the brake. If required, the engines should be used to take the weight off the chain. The position of the vessel should be recorded at the time of letting go so that the position of the anchor can be ascertained. For anchoring small and medium size vessels (under 65,000 DWT) in deep water above 40 meters, the anchor should be walked out all the way controlled by the windlass and brake until the vessel is brought up to the required number of shackles. The windlass should be disengaged and the anchor and cable held on the brake and stopper bar. (The advantage is to avoid excessive strain on the brakes and on the bitter end, less brake wear)
Large Vessels For anchoring large vessels, DO not “LET GO” anchor and should be walked back with the windlass under power/gear

Under normal circumstances when the vessel is at the required position and stopped relative to the ground, the anchor should be walked out to the bottom. Continue to walk out the anchor, controlled by the windlass gear until the vessel is brought up to the required number of shackles. Once anchored the stopper bar and brakes engaged prior disengaging the gear. The position of the vessel should be recorded at the time of anchoring so that the position of the anchor can be ascertained.
25.5
SECURING OF ANCHORS AND CABLES WHILST AT ANCHOR
When vessel is anchored, the following to be adhered to at all times. •
Anchor should be secured by the stopper bar and pins once the anchor is brought up
•
Anchor not in use is housed and properly secured to prevent accidental release
•
The anchor windlass brake to be fully tightened and gear to be disengaged
•
Anchor to be marked using a flag for easy identification by the Bridge officer against dragging of anchor
25.6
SECURING OF ANCHORS AND CABLES
Prior commencement of sea passage, each windlass shall be physically inspected by Chief Officer to ensure: •
The anchor is hove right home before securing to eliminate any free movement and subsequent banging when underway
•
Stopper bar properly located and secured with pin
•
Secondary (additional) securing arrangement holds the anchor tightly against landing place
•
Is the stopper bar due to chain wear and tear and size deterioration does not sit then additional lashings taken to compensate
Results shall be entered in the Deck Log Book.
25.7
ADVERSE WEATHER
When Underway The Master is to ensure that additional securing arrangements are made in anticipation of adverse weather. The securing arrangements should be checked every three days during prolonged periods of heavy weather (this may mean altering course to allow safe access to the Forecastle).
At Anchor If the Master or Officers are in any doubt as to the security / safety of the vessel, the engines must be immediately brought to readiness. The Master should assess the situation and if thought necessary, weigh anchor. This decision should not be left too late so that additional weight is put to bear on the cable and windlass when heaving. The stress on the cable can be eased by using the engine or using the rudder to attempt to reduce yawing, especially in a current.

Frequent weather forecasts must be obtained and evaluated when the vessel is anchored. Assessment should be made as to the direction of the wind “is it a lee shore”, what is the holding ground like etc. While at anchor, considerable dynamic stress on the anchor system may be induced due to yawing of the ship under influence of wind and tide. This yawing can be moderated by lowering a second anchor on to the sea bed and when 2nd anchor is being made ready the anchor and the shank to be lowered inside the water to dampen the effect of anchor banging against the ship side due to rolling
Freezing Weather Precautions Chief Engineer is responsible for ensuring that steam operated windlasses are protected against consequences of freezing, when in operation. This can be accomplished by: •
Ensuring that deck lines and steam chests are thoroughly drained, with drain valves left in open position or
•
Windlasses are continuously operated at slow speed
•
Deck OOW is responsible for ensuring that program is carried out in accordance with Chief Engineer's instructions
25.8
BITTER END HAMMERS
Designated and appropriate hammers should be provided to release the anchor bitter ends, these hammers shall be conspicuously marked and placed on site for easy availability.
25.9
LOSS OF ANCHOR / CHAIN
If the vessel loses an anchor, the vessel is to immediately contact Thome Ship Management emergency room, and local agent. The estimated position of the anchor should be verified and passed as part of the original message. It may be possible if time schedules permit for the anchor and chain to be recovered and reattached to the vessel. In any case, the vessel should review and prepare all equipment to achieve this outcome, ordering additional equipment as required.

CARGO HEATING Purpose To specify procedures and guidelines on Cargo Heating
Application All vessels
Responsibility Master Navigating Officers Watch-keepers
26.1
CARGO HEATING GUIDELINES
The type of crude oil cargo will determine cargo heating or heating program for the voyage. Aromatic crude oils contain little or no wax. They can be permitted to cool during the voyage, provided the vessels heating system is capable of raising the cargo temperature to the required pumping temperature before discharge. Paraffinic crude oils must be maintained above a certain critical temperature, i.e. the cloud point to avoid phase separation of the wax they contain. Charterers normally state the heating requirement for the voyage and must be followed. The operators must be contacted if in any doubt. Excessive heating of cargo will: •
Increase light end vapor losses
•
Reduce the solvency of the crude for crude oil washing
•
Accelerate the fall out of sediment and water otherwise suspended in the crude, waste fuel
•
Increase the possibility of vapor lock problems with the cargo pumps during discharge
During carriage of heated cargoes, cargo temperatures, measured at three points in each tank must be daily taken and recorded.
26.2

o
o
From the above, it is clearly noted that a ship’s cargo heating system on a conventional crude tanker is designed with quite a high degree of safety margin. In general, gradually raising the temperature 3-4F per day will be quite easy, even with only 60-70% of the heating coils on board working. The most important aspect, which needs to be realized, is that with cargo heating, the steam’s latent heat is necessary. There is no use or advantage gained if steam passes through the cargo tank and goes back to the hot well as “live steam”. Therefore it is important that correct control of heating coil returns and pressure to inlet systems is practiced. The hot well system, where the condensed water returns from the coils, must be protected from any unforeseen cargo return from the heating system. The duty engineer and motorman must take regular spot checks in that vicinity because it very often has large volumes of oil coming into the cascade tank suddenly. Any of this oily water entering the boiler can be disastrous. A very good secondary precaution would be to cover the top of the hot well with a layer of sponge or oil-absorbent matt and replace/squeeze at convenient intervals. This is a good back up for an emergency oil leak into the hot well tank. Most vessels now are fitted with “Turbidity Sensors“ or “Sonic Interface Detectors“ that raise an alarm condition if any contamination in condensate return is detected. The correct function of heating coil traps is extremely crucial to the performance of the cargo heating system. Many times this is the biggest problem and no one realizes it with everyone simply trying to increase steam pressure etc. to achieve better results. Once again going back to basics, where it is extremely crucial for steam to condense and latent heat to be given to the cargo. With a full cargo, generally, it is very unlikely that steam will come back from heating coil returns since almost all of it should condense prior to coming up. However, if your traps are blocked there is no water return back and, obviously, no heat transfer or exchange. On many old vessels, the heat coil traps are either broken or damaged from inside. Clogging of trap filters with rust and fine debris is common. Therefore the best practice is to include the overhaul of steam traps in Planned Maintenance System. However in an emergency the best solution is to either bypass the same or simply remove the internal components. A drain on the outlet can be opened to check if there is excessive steam going back to the hot well.

PRECAUTIONS
One of the major and time consuming repairs conducted on board involves heating coils. Although it is recognized that such fittings do deteriorate due age and reaction to aggressive cargoes, a majority of these problems can be eliminated if following simple precautions are adhered to:
26.4
•
Heating coils blown through dry with compressed air in cold weather locations with sub zero temperatures
•
Vacuum created in the coil is broken by keeping drains open on stopping cargo heating
•
Cargo heating is always commenced through by opening the header inlet valve slowly with low pressure in order to avoid water hammer
•
Pipe clips must all be tightly secured within the entire tank length
TESTING FOR TANK LEAKS
During dry docks it is best that the heating coils be tested to 1.5 of its working pressure. The method recommended is by filling the coils with fresh water and using a hydraulic pump the pressure is built up and inlet and outlet valves shut leaving the coil pressured. The pre s s ure ga uge is the n obs e rve d to che ck for drop in line pressure and the second officer, third officer, pumpman or cadet is then sent into the tanks for visual verification. 2
O the rwis e a ll s hips a re ge a re d to pre s s ure te s t the ri heating coils minimum up to 7kg/cm , utilizing the compressed air system on board. A hydrostatic test is the most reliable and efficient check, although even when conducted under pneumatic pressure it is fairly reliable. The test procedures for both are almost the same. The only difference being that in case of hydrostatic testing the heating coils are completely filled with water prior exerting the compressed air pressure. If ove r a pe riod of 4 to 5 m inutes the pressure drop is insignificant, then we can assume the coils are tight. Alternatively if the pressure across the coils drops gradually or suddenly, then shut all the individual coils and start checking individually. Test procedure for heating coils should be as follows: •
Connect test jig to preferably the inlet header of deck steam manifold
•
Shut main steam inlet valve to the respective header
•
Keep all inlet valves to individual coils open
•
Shut heating coil return outlet valve to main line
•
The complete heating coil loop is interconnected with the main line inlet or outlet valves being isolated
•
Increase compressed air pressure gradually till gauge indicates around 7 kg/cm (as rated)
•
Open the heating coil drains and check all coils giving sufficient water or air pressure, confirming no choking or blockage of pipelines
•
Stop deck air supply to header and monitor the pressure gauge. An insignificant pressure drop over 3 to 5 minutes will confirm system is "tight"

•
Alternatively if the pressure drops gradually or suddenly, shut all the individual coils. Then open one by one each coil and identify the individual leaks
•
The best time and opportunity to pressure test heating coils is when tanks are empty and gas free. By this way leaks can be easily spotted at location when system is under test. However it is not necessary to wait for such rare opportunities. In fact once leaks are ascertained, then only suspected tanks may need washing and gas freeing for inspection and repairs
Caution during testing •
If pressure drop prevails with all coils shut, there is a possibility that: o
Main steam inlet valve to header is leaking
o
Some or all heating coil steam supply valves are not tight and subsequently the main valve from header to return line is leaking
Remedy It will be necessary to blank the main steam inlet and return valves respectively and then do the test. Although this is best solution prior commencing any testing, it becomes very time consuming. Hence it is best to leave it for headers with leaking valves. •
It must be remembered that although pressure drop will indicate possibility of leaks the exact location or extent of damage can only be estimated by visual examination
Frequency of test •
26.5
The testing of heating coils to be done during the routine cargo tank inspection as per Thome and owners requirement
PRELIMINARY PRE-HEATING CHECKS
Prior to any cargo heating, it is very essential to know the following: •
Domestic fresh water consumption
•
Distilled water consumption
With regard to distilled water consumption, daily loss from engine room service systems must be figured out, i.e. with deck steam and cargo heating closed. This analysis is extremely important prior to commencing any cargo heating, otherwise at a later stage, it is very difficult to know or determine which side of the fence the problem lie. In essence, many times people suspect water loss on deck or cargo tanks and the problem may be in the economizer or water systems within machinery spaces. Therefore, it is generally a good idea to do a 12-hour consumption check by having steam heating on deck closed. The best time to do this is when doing repairs on the cargo heating system on deck, or prior to commencing the heating operation. The hot well system, where the coil return lines come back, must be protected from any unforeseen crude oil return from the heating system. The duty engineer and motorman must take regular spot checks in that vicinity because it very often has large volumes of oil coming into the cascade tank suddenly. Any of this oily water entering the boiler can be disastrous. CONTROLLED

A very good secondary precaution would be to cover the top of the hot well with a layer of sponge or oil-absorbent matt and replace/squeeze at convenient intervals. This is a good back up for an emergency oil leak into the hot well tank. Some vessels are fitted with "Turbidity Sensors" or "Sonic Interface Detectors" that raise an alarm condition if any contamination in condensate return is detected. This is a necessary feature in tankers these days. The correct function of heating coil traps is extremely crucial to the performance of the cargo heating system. Many times this is the biggest problem and no one realizes it with everyone simply trying to increase steam pressure etc. to achieve better results. Once again we go back to "school economics" where it is extremely crucial for steam to condense and latent heat to be given to the cargo. With a full cargo, generally, it is very unlikely that steam will come back from heating coil returns since almost all of it should condense prior to coming up. However, if your traps are blocked there is no water return back and, obviously, no heat transfer/exchange. On many old vessels, the heat coil traps are either broken or damaged from inside. Filters get clogged and rusted, therefore, the best solution in an emergency is to either bypass the same or simply remove the internal components. A drain on the outlet can be opened to check if there is excessive steam going back to the hot well tank.
26.6
GENERAL CARGO HEATING PROCEDURES
The main line is to be warmed up to avoid water hammer prior start of heating. When commencing cargo heating for each steam header, it is very important that coils are opened gradually and slowly. Generally, coils will have water inside and this causes excessive hammer. On old ships, structural fatigue on welded seams is common, and water hammer can cause damage. The inlet must be first opened, and return shut. Thereafter line pressurized and drain opened on deck slowly to check condensate quality. Take precautions against oil Spillage on deck in case coil has heavy ingress of contaminant. The pressure of steam on the entire heating system is another critical aspect. If all coils and valves are fully opened, the pressure in the aft tanks will be more and there may be nothing reaching forward. Typica lly, for e xa m ple , with 5kg of s te a m s upplie d, yo u m a y ha ve no m ore tha n 1kg steam pressure reaching forward. To summarize, it is very important for the engineer to adjust the valves so that pressure on the main line i.e. equally distributed from forward to aft. To achieve this, one of the best methods is to install three independent pressure gauges on the steam manifold header in the center, amidships and aft (last cargo tank). Do not s im ply re ly on the s team pressure on the indicator deck line in the engine room because, depending on the location of the pressure gauge being before or aft the main deck steam valves, the reading can be misleading. Check what is physically present on the main steam line on deck. The recommended way for adjusting efficient cargo heating is to keep all steam inlet valves for the tank open and regulate the deck line pressure by throttling the outlet of the tank return line valve on the manifold. Generally, you will notice that the return line valves for forward tanks may need to be 100% open, mid ship tanks 70%, and aft tanks 40%.

It is not wise to adjust each coil individually but rather the tank common return valve be throttled. Thereafter, depending on each cargo tank temperature, you can shut off or increase the total number of coils you need. The re a s on for throttling the ta nk outle t va lve s , ra the r tha n inle t is be ca us e the e ntire coil will be a t a higher pressure than the head of the oil within tank. This therefore will avoid a contamination by oil in the condensate return. Throttling inlet steam drops the pressure and increases velocity within coil. When this condenses it leads to internal pipeline pressure drop which may be lower than the head pressure of cargo within the tank. To achieve the desired temperatures, it may be necessary to reduce heating to center tanks so that additional heat can be applied to wing tanks (single hull tankers). The te m pe ra ture is to be brought up gra dua lly. He a ting is m ore e fficie nt a t a nc hor tha n unde rwa y. Records of past voyages are to be consulted. It is re com m e nde d tha t a re s pons ible office r is de le ga te d to s upe rvis e the ope ra tion of starting cargo heating rather than leaving it to the pumpman who may not understand the basics. Ke e p a log with da ily ca rgo te m pe ra ture s a nd s te a m pre s s ure on forwa rd, m id a nd a ft headers. Also, log the percent each return manifold is open so that on a daily basis you can decide on how to change their positions. Normally, you achieve a good balance within 3-4 days of trial and error. Thereafter, rarely will you need to adjust the position
26.7
SYMPTOMS OF COIL LEAKS
Leakage of heat coils in tanks generally reflect the following symptoms: •
Oil traces coming into hot well tank
•
In ca s e s te a m pre s s ure is ve ry high, the n ins te a d of oil tra ce s the re will be steam loss. This obviously means excessive consumption of fresh water. The quickest way to identify this is to shut each header temporarily for 15-20 minutes and reduce the steam pressure within the coils in the tank. If there is any coil leakage, there will be oil seeping into the system and when you are commencing re-heating, oil smears will come out in the drain. In this way, the defective coil can be isolated
Heating Coil breakage on deck head will cause steam smear in the vapor space. This is easy to identify by touching the deck area adjacent to the steam manifold or penetration joints. You will immediately notice a much “hotter” steel environment. In addition, a further check for steam emitting sound i.e. if the leak is large.
26.8
SHUT DOWN PROCEDURE AFTER CARGO HEATING
Heating is normally kept on until the cargo is at the level of the heating coils. Heating after that point will cause excessive vapor and contribute little to a discharge operation. As the ta nk le ve l fa lls ve ry low a nd the coil ge ts tota lly e xpos e d, s te a m in the he a ting coils m us t be gradually reduced. Otherwise, you could have damage at bends, etc. W he n ca rgo heating coils are shut down completely, the drain must be opened in order to break the vacuum. For guidance, once the pipeline steam within the heating coil system condenses it causes a lot of pressure on the exterior wall and, especially on older ships, you tend to get collapse fatigue.

27.1
GENERAL
Crude oil tankers may use crude oil from the cargo as a washing medium. Under normal operating circumstances, for the vessels on the Crude Oil Trade and equipped with the Crude Oil Washing Systems approved by the Flag State Administration, C.O.W. is the primary and the most efficient method of tank cleaning. This operation, subject to Charterers permission may take place in port or at sea between discharge ports. It is most commonly carried out while the tanker is discharging cargo and permits the removal of sediments that have settled from the cargo. These sediments are then discharged with the cargo. This results in: •
Increased out turn of cargo.
•
Less oil is retained on board, thus less oil is available to cause pollution.
•
Increased tonnage for the next cargo (more freight earned).
•
Reduction in corrosion due to less water washing of the tanks.
•
Reductions in the time and cost of routine tank cleaning and tank cleaning for dry dock.
•
Limitation of pollution threat when using Crude Oil Washed cargo tanks for the loading of ballast.
•
Reducing workload of de-sludging before drydock / repair periods.
•
Reducing damage to pumps and valve seats caused by deposits, and sediment in system.
Any vessel equipped with an approved C.O.W. system is required to have on board an approved “Crude Oil Washing Operations and Equipment Manual”. This manual must always be referred to

prior to C.O.W. operations. The procedures and checklists contained in the vessels “C.O.W. Operations and Equipment Manual” must be strictly adhered to. It is absolutely essential that the inherited dangers of C.O.W. are recognized. C.O.W should be suspended in the case of: •
Failure of the inert gas system.
•
Oxygen content exceeds 8% by volume. or below or below terminal minimum requirements.
•
Cargo tank pressure falls below atmospheric pressure. (min pressure in tanks 100 mm WG)
•
Any water content not discharged prior to C.O.W.
•
Leakage from the C.O.W. system.
•
Cargo unsuitable for C.O.W.
•
When the safety of the operation cannot be maintained.
When it is required to carry out crude oil washing operations during discharge the Master must inform the competent authority and the Terminal (or vessel when the ship-to-ship transfer is involved) at least 24 hours in advance. Crude oil washing may only proceed when written permission has been obtained.
27.2
PRIOR ARRIVAL
Advance Notice See International Safety Guide for Oil Tankers & Terminals (ISGOTT) chapter 11.5. The ‘Pre-Arrival Checklist at Discharge Port’ contained in the Class Approved ‘Operation and Equipment Manual for the Crude Oil Washing System’ is to be completed. A copy of this checklist must be filed in the Cargo Checklists file in the cargo control room. The Crude Oil Washing Plan The Chief Officer must prepare a COW plan and permission to COW must be requested well in advance of the vessel's arrival at the discharge port. The COW plan must be incorporated in the ‘Discharge Plan and Oil Transfer Instructions’ prepared by the Chief Officer and each stage must be carefully arranged so that, as far as possible, COW does not delay the discharge programme. The COW Plan must take into account Charterer’s requirements and the requirements of the vessel’s Class Approved Crude Oil Washing Manual. Sufficient tanks will have to be washed to enable vessel to load heavy weather ballast in compliance with Annex I of MARPOL. Heavy weather ballast must never be loaded into a tank which has not been COW (except in emergency situations). At least one quarter of the cargo tanks should be crude oil washed for sludge control purposes on a rotational basis although it is not necessary to wash a tank more than once in four months. In case of multiple grades it will be necessary to start planning for COW at the loading port.

A multiple grade load reduces flexibility for COW. •
Loading and discharging plans must be planned in conjunction with COW plans.
•
Hull stresses, draft and trim may cause problems.
•
Adequate separation of grades must be achieved.
•
Cargo which is to be discharged first should be loaded in the slop tank(s) so that the slop tanks can be used for a COW supply. If possible, when two grades are carried, each slop tank should carry a different grade (provided cargo segregation can be maintained)
•
When multiple grades are carried, COW should only be done using the same grade of oil as that in the tank unless permission is obtained from Charterer. Care will be required in order to avoid cargo contamination.
Control of tank atmosphere The ship should arrive at the unloading port with all cargo tanks pressurised with good quality inert gas. A positive pressure of at least 100 mm water gauge should be maintained in the ullage space and the oxygen content must not exceed 8 % by volume at all times. (Or lesser oxygen content % if required by terminal) If the pressure falls below the low pressure alarm level, it will be necessary to start the inert gas plant to restore an adequate pressure on the system. In this case, particular attention should be paid to obtaining an oxygen content of 5 % or less by volume on the inert gas supply before introducing the gas in the cargo tanks.
Precautions against leakage from the washing device The prevention of leakage during the COW process must be considered as being utmost important and having a higher priority than the COW process itself. Although COW is vitally important to the elimination of operational pollution by tankers, this objective will be cancelled if the COW process itself causes leakage and pollution. That is the reason why, before arrival at the unloading port, the tank washing system should be tested to normal working pressure and examined for leaks. Any leaks found should be made good and the resultant oil cleaned up. Additionally annual test is to be carried out at 1.25 times the working pressure of the COW line. Date of testing is to be recorded. Do this by opening a COW machine at one of the fwd tanks and expel any air by gradually pressurizing the system using the stripping pump or a cargo pump. Verify the accuracy of COW line pressure gauges - remember that there should be a gauge at both ends of the line and a gauge amidships. Tighten up any leaking flanges or replace gaskets as necessary. Check that all blanks from COW line to tank cleaning heater are blanked and that any spool pieces between COW line and heater are in place. Ensure that all portable washing machine connections are blanked and capped were applicable. In the same way all the machines which are to be used should be operated briefly to check for leaks beyond the shut-off valve. Carry out any maintenance on COW machine drive units which have been reported as defective.

AT BERTH
The system must be under continuous observation. For doing this the checklists for Before, During and After COW operations, contained in the Class Approved ‘Operation and Equipment Manual for the Crude Oil Washing System’ are to be used. Copies of these check lists must be filed in the Cargo Check-lists file in the cargo control room (CCR). During the COW process the involved officers and ratings must be alerted about to the possibility of leakage. They have to notify the chief officer should any be noticed, regardless to its importance. The COW must be stopped when any sign of leakage or fault in the tank wash system is discovered. Equipment and fittings on the main deck that are not part of the COW system itself must also be carefully watched as sources of leakage. Some of these can be butterworth plates, sounding tube covers, tank tops, vapour line fittings, PV valves. During COW, the AB on watch must keep a particular close watch upon the surrounding area of the vessel. This is utmost important during night time. This surveillance will guard against leakage from overboard valves, from side and bottom shell seepages, and from escapements through the scupper plugs.
Use and control of inert gas Starting of discharge Pressure may be released for ullaging, sampling and water dips before discharge and at this stage the oxygen level in tanks should be checked to ensure that it is below 8 per cent by volume. The supply of inert gas must be commenced immediately before the commencement of cargo discharge to avoid a vacuum in tanks. By this means a safe condition will be maintained throughout discharge. Apart from this initial release of pressure the pressure in the cargo tanks should always be above atmospheric pressure. Under no circumstances should air be allowed to enter any tank which is to be crude oil washed. Before COW Before each tank is washed, the oxygen content should be checked with the portable oxygen analyser to ensure that it does not exceed 8 per cent by volume. During COW The oxygen content and pressure of the inert gas being delivered during the washing process should be continuously recorded. In case of failure of the inert gas plant, the crude oil washing must be stopped.
Tanks to be washed Rules Before departure on a ballast voyage, sufficient tanks must have been crude oil washed to permit compliance with the draught and trim requirements. If for any operational or maintenance reasons, CONTROLLED

there is the likelihood or intention to put ballast in any other tanks during the voyage then these tanks must also be crude oil washed. Additionally, one quarter of the remaining tanks must be crude oil washed for sludge control on a rotational basis. This additional quarter may include the exceptional ballast tanks mentioned above but, in usually conditions, no tank need to be crude oil washed more than once in every four months for this sludge control. Adaptation to the circumstances The indicated periods between two crude oil washings is depending of the nature of the loaded cargoes. So several successive loading of light crude oil should allow to increase this period then in case of heavy crude oils, it would be reduced. Before dry docking, all the cargo tanks should be crude oil washed. Slop tanks In order to avoid accumulation of settled residues, the slop tanks and especially those which have been used for load on top purposes should be washed at every discharging.
Tank washing procedures For details on each vessel specific refer to the Crude Oil washing manual available on board. Sequence of tank washing (non SBT tankers) Priority should be given to COW of the departure ballast tanks. In such conditions, freeboard problems while alongside, the top ballasting can be concurrent with discharge. The venting of tank gases to atmosphere within port areas will also be avoided. Multistage washing In some cases, each tank should be washed on two stages, the side wash and the bottom wash in order to improve the ship's performances. During bottom washing, the oil depth will be kept as low as possible toward the end of the washing and well drained to achieve the best results. The trim during this last phase should be not less than the required trim given in the COW Operational and Equipment Manual. Extent of washing The programs of washing reported in the COW Operation and Equipment Manual will be adapted for each discharge plan. In particular the number and angles of top and bottom passes, the pitch angle and the speed of the guns, their cycle time and the time taken to wash each tank which have to be estimated and mentioned. Multi tank washing Always in order to minimise ship delay, it is desirable to COW several tanks simultaneously provided that: •
All the guns on any tank are in use at one time
•
Pressure of the tank washing line does not fall below the minimum required as specified in the COW Operation and Equipment Manual.
•
The number of guns operated simultaneously remain compatible with stripping capacity, in particular when cargo eductors are used.

Under no circumstances the stripping rate must be lower than 1.25 times of the total output of the guns used simultaneously during bottom washing. Supply of wash oil The maximum allowable pressure is mentioned in the COW Operation and Equipment Manual. High precautions have to be taken to establish the pressure in order to prevent hydraulic shocks and over pressure. Two pressure-gauges fitted aft and forward the wash line will be used and checked for this purpose. As long as the back pressure of the discharge lines is high enough, the wash oil would be supplied directly from the delivery of the discharge pumps, according to shore possibilities. This method allows to keep the maximum discharging rate. To retain the required pressure, it may be necessary to reduce the number of machines being used or, when the ship's facilities allow this possible, by throttling in the discharge valve of the cargo pump used to supply the wash oil. Alternatively, when the back pressure is too low, it is necessary to dedicate one main pump to supplying the wash oils and accept the reduction of the discharging rate. The close cycle re-circulation via the slop tanks and eductors is not suited to routine crude oil washing as it causes unnecessary delay. It also increases risk of passing sediment through the machines and of using oil which has lost much of its solvent effect. Discharge of tank washings In order to maintain the performances as high as possible, recovered residues should be co-mingled with the main cargo unloading. During multi-stage washing of the tank sides, this co-mingling occurs automatically. During bottom washing, it could be preferable - consideration has to be taken about ship's facilities - to use either the self priming system or the eductor stripping system. When the self priming system is used, the washing oil and recovered residues are discharged directly with the cargo and several tanks could be drained simultaneously by the same pump. Nevertheless the efficiency of stripping could be affected by this method. Then a good care should be kept on the oil levels in tanks being washed. When eductors are used, the washing oil and recovered residues are collected into slop tanks and caution must be taken to avoid any over filling before the slop tank is discharged to shore. Crude Oil washing check lists The check lists included in the crude oil washing manual are to be used.
Stripping and draining procedures Stripping and draining of cargo are of utmost importance for charterer's and cargo receivers, as they require to recover the whole cargo which have to be loaded. Draining and stripping of tanks Two systems could be suitable to drain the tanks: •
The self priming "VAC STRIP" system: As a tank or tanks approach draining levels, the system is manually set in operation. Thereafter vacuum pumps automatically draw off excess of gases and the pump discharge valve closes as flow decreases

OMD Document No. 027 Crude Oil Washing System
The closed cycle system using eductors: This system is very efficient but occurs some delay. Attention should be paid to the drive pressure which has not to fall below a minimum indicated in the COW Operation and Equipment Manual. A good indication that a tank is empty is when the vacuum show by the remote eductor section gauge in the cargo control room, drops completely away. When bottom crude oil washing of any tank nears completion, the tank washing machines in that tank should be shut off. When all washing is completed, sufficient time should be given to complete the draining. Hand dipping must be carried out to achieve the best stripping and the vessel should be trimmed by the stern sufficiently to enable the cargo to run aft to the tank suction. The trim should be as much as possible with due regard to berth security and tank stresses, but should not be less than the minimum required by the COW Operation and Equipment Manual.
Draining of cargo pumps and lines On completion of discharge, all top and bottom lines should be dropped back to either slop tank via the direct loading drops and bottom pump room crossovers. The manifolds have to be vented to permit the oil to drop back. Draining COW lines When COW is completed it is important that the COW lines and branch pipes are drained of oil in order to: •
Improve vessel out-turn figure
•
Reduce the danger of damage caused by thermal expansion of liquids in pipelines
•
Reduce the effects of corrosion on pipeline internals
•
Ensure that washing lines are clean for any subsequent water washing that may take place on the ballast voyage
COW line draining is achieved as follows: Using vessels stern trim, drain line to port and starboard slop tanks - break vacuum in line by opening one forward COW machine. Oil in branch lines can be drained to cargo tanks by opening the appropriate COW machine valve. Pump room COW lines should be drained using the stripping pump as part of the final line draining programme. According to MARPOL requirements, when all lines are drained and cargo tanks dipped manually, the stripping pump can be set to discharge the line draining collected in each slop tank, via the direct stripping suctions, discharging through the special line to the manifold.
Ballasting of cargo tanks Discharging of cargo has to be planed in order to discharge the cargo contained in the heavy weather ballast tanks as early as possible. These tanks must be crude oil washed before ballasting. Good care must be taken while bottom washing with frequent monitoring of soundings, to ensure that the tank bottoms are well cleaned. Once the tanks are empty to the satisfaction of the chief officer, with

the main suction and stripping valve controls lashed in the closed position together with all gun stop valves on those tanks checked shut, then ballasting can be commenced as soon as required.
Prevention of hydrocarbon emission During cargo discharge, there is no hydrocarbon emission to atmosphere, with vacant cargo space being replaced by inert gas. Also, when ballasting cargo departure ballast tanks concurrently with the discharge of other tanks, again there should be no hydrocarbon emission as the rate of supply of inert gas is reduced automatically to maintain the round over pressure.

GENERAL REQUIREMENTS
Limitations of Electronic Charts Electronic Navigational Charts (ENCs) are vector electronic charts that conform to International Hydrographic Organization specifications. They are compiled from a database of individual items (objects) of digitised chart data which can be displayed as a seamless chart. When used in an Electronic Chart Display and Information System ECDIS, the data is re-assembled to display either the entire chart image or a user-selected combination of data. ENCs are intelligent in that systems using them can be set up to give warning of impending danger in relation to the vessel’s position and movement. ENC Updates are issued for all Permanent Chart Updating Notices to Mariners and all chart-specific temporary and preliminary Notices to Mariners. Mariners should be aware that it may not always be possible to issue updates for temporary and preliminary Notices to Mariners that are not chart specific. Mariners should consult the paper weekly Notices to Mariners booklet. Because of the developing nature of ECDIS and because global coverage of ENCs is not yet available, there are vastly varying degrees of experience of the practical, operational use of ECDIS. Mariners should satisfy themselves that their ECDIS provides all the navigational functionality that they will need and that they are familiar with the operation of this functionality. Mariners should be aware of the significant changes in navigational practice required by the introduction of ECDIS and of the need to manage these changes in a careful and prudent manner. The limitations of electronic charts are as follow: •
T & P notices not updated
•
Appearance and content of data may differ substantially from similar data in paper chart form
•
No data from nautical publication imposed
•
Rely on accuracy of GPS

Without selecting different scale charts, the look ahead capability may be limited. This may lead to inconvenience when determining range or bearing of distance objects
Approved ECDIS Use of ECDIS as a stand-alone navigation system without paper charts requires two fully independent, IMO type approved vector chart systems. Appropriate entries should be made in Cargo Ship Safety Equipment Certificate Form E, Section 3, Details of navigation systems and equipment. All navigation officers should undergo an appropriate training course. Before a watchkeeping officer or master intends to use a compliant ECDIS as the primary means of navigation they should complete a generic ECDIS Operators Course complying with IMO Model Course 1.27 - The Operational Use of Electronic Chart Display and Information Systems (ECDIS) as well as type specific training. Whenever a single or non-approved ECDIS, ECD or INS is fitted, a caution notice should be posted on the unit indicating that the unit may be used for reference only.
Use of ECDIS ECDIS is capable of operating with both Raster Navigational Charts (RNC) and Electronic Navigational Charts (ENC). However, when used in the Raster Chart Display System mode (RCDS), the International Maritime Organisation (IMO) performance standards for ECDIS stipulate that the system has to be used ?in conjunction with an appropriate portfolio of up-to date paper charts?. A risk assessment should be undertaken prior to authorising the use of ECDIS in the RCDS mode for primary navigation. •
The risk assessment will depend upon a vessel’s physical dimensions, hydrostatic characteristics and area of operation and must address risks to own ship, other ships and environment resulting from ECDIS -related navigation hazards.
•
The assessment should ensure all hazards have been identified and a system to manage the risks associated with those hazards has been successfully established onboard.
Vessels should be guided by the “MCA Marine Guidance Note MGN 285 (M+F) Electronic Charts The Use of Risk Assessment Methodology When Operating ECDIS in the Raster Chart Display System (RCDS) Mode” In addition, below are some generic examples when conducting risk assessment when using ECDIS. Vessels are encouraged to use the same to make their own ship specific risk assessments when using ECDIS. Sample risk assessments are also provided to the vessels for their additional guidance. •

INTRODUCTION
The SOLAS Convention includes a requirement for all ships to carry to up-to-date nautical charts and publications for the intended voyage. This carriage requirement may be satisfied fully or partly by electronic means. A navigational electronic chart system is a general term for all electronic equipment that is capable of displaying a vessel’s position on a chart image on a screen. There are two classes of navigational electronic chart systems. The first is an Electronic Chart Display and Information System (ECDIS), which meets IMO/SOLAS chart carriage requirements. The second is an Electronic Chart System (ECS), which can be used to assist navigation, but does not meet IMO/SOLAS chart carriage requirements. Electronic Chart Display and Information System (ECDIS) means a navigation information system which, with adequate back up arrangements, can be accepted as complying with the up-to-date chart required by regulation V/19 & V/27 of the 1974 SOLAS Convention. ECS is a navigation information system that electronically displays vessel position and relevant nautical chart data and information from an ECS Database on a display screen, but does not meet all the IMO requirements for ECDIS and is not intended to satisfy the SOLAS Chapter V requirements to carry a navigational chart. The requirements for charts and publications to be carried as required by SOLAS Chapter V can be fulfilled by: •
Carriage of official and up-to-date paper charts, or
•
Carriage of a type-approved ECDIS, using official and up-to-date Electronic
Navigational Charts (ENC) together with an appropriate back up arrangement. After the amendment of SOLAS regulations 1 July 2002 it is allowed to replace the paper charts and publications by electronic means if a suitable back up is provided. IMO Performance Standards require that the “overall system” include both a primary ECDIS and an adequate independent back up arrangement that provides: •

OMD Document No. 028 Electronic Chart Display and Information System (ECDIS)
A means to provide for safe navigation for the remaining part of the voyage in case of ECDIS failure
Paper charts and publications continue to be the minimum requirement for back up purposes. There are a number of possible options that could meet these requirements, including: •
A second ECDIS connected to an independent power supply and a separate GPS position input;
•
An appropriate up-to-date folio of official paper charts for the intended voyage;
•
An ECDIS operating in the RCDS mode of operation; and
•
A radar-based system known as “Chart-Radar” according to IMO Performance Standards for Chart Radar.
Different Back up arrangements are acceptable by different national maritime administrations and this should be verified with the Flag State of the vessel.
Digital Charts There are two kinds of official digital charts commonly available; Electronic Navigational Charts (ENC) and Raster Navigational Charts (RNC). ENC stands for “Electronic Navigational Chart”. By IMO definition ENCs can only be produced by or on the authority of a government authorized Hydrographic Office or other relevant government institution. Official ENCs are vector charts compiled from a database of individual geo-referenced objects from Hydrographic Offices archives including existing paper charts. When used in an ECDIS, the ENCs content can be displayed as a seamless pattern in user selected scales presenting user selected chart items. Due to the limited physical size and the limited resolution of computer monitors the chart image generated from ENCs does not fully imitate the known appearance of the paper chart. This apparent disadvantage is compensated by the ENC being a database: special ECDIS operational functions continuously retrieve the ENC content to give warning of impending danger in relation to the vessel’s position and its movement. RNC means “Raster Navigational Chart”. Official RNCs are digital raster copies of official paper charts. When displayed on an ECDIS screen they appear to be a facsimile of the paper chart however, they contain significant metadata to ensure that they have certain minimum functionality; e.g. a means for geo-referencing positions on the chart, automatic updating of the RNC from digital files (and the ability to show the state of correction) and the display of the RNC in day or night colours as appropriate. As a digital copy of the original paper chart, a RNC has no intelligence and other than visually, cannot be interrogated for e.g. automatic route checking or hazard warnings; however some of these limitations can be minimised by manual user input to the ECDIS. The IMO performance standards for ECDIS states that where official ENCs are not available, RNCs may be used in ECDIS to meet carriage requirements. However, when the ECDIS is using RNCs it should be used together with an appropriate folio of up to date paper charts. The use of official ENCs in a tested, approved and certified ECDIS and with appropriate back up arrangements, is the only paperless chart option for vessel navigation.

ENC Visualization An ENC contains an abstract description of geographic entities but does not contain any presentation rules. All presentation rules to get the ENCs content displayed are contained in a separate ECDIS software module - the “Presentation Library”. Both the geo-referenced objects contained in the ENC and the appropriate symbolization contained in the Presentation Library are linked to each other in the ECDIS only when called up for display. The resulting image will differ depending on the selected sea area, the intended display scale and the mariner’s pre-settings like ambient light conditions and other operational conditions. The definition of the Presentation Library for ENCs is contained in Annex A of the IHO Special Publication S-52, Appendix 2 “Colours & Symbols Specifications for ECDIS” (current edition 3.3/2004) and is mandatory for all ECDIS. The strict separation between the Hydrographic information contained in the ENC, operational information taken from navigation sensors and their situation related presentation by means of the Presentation Library gives the flexibility to display the diversity of ECDIS information, e.g.: physical chart information, (e.g. coastline, depth contours, buoys), •

Because much experience is embodied in the paper chart, and to avoid confusion in the extended period while paper charts and RNCs as compared to ENCs co-exist, the two presentations should be similar wherever possible. The ECDIS Presentation Library follows that of the paper chart to the widest extent possible. However, studies and early experience indicated that good visual communication between the ECDIS display and the user requires more flexibility of display than is available from paper charts.

Probably no other display application is as demanding as that of ECDIS. Since colour is a prime means of distinguishing features, the maximum range of colours should be available. However, the colours selected must be such that they can be clearly discriminated by a mariner with no more than adequate colour vision, and colour induction effects must be avoided (for example a small green object on a saturated blue background will tend to appear yellow). The ambient lighting on the bridge varies between the extremes of bright sunlight, which washes out information on the display, and night, when the light emitted by the display has to be low enough that it does not affect the mariner’s night vision. The colour and symbol specifications of S-52 have been designed to meet these difficult requirements rather than less demanding normal day conditions. Because the ECDIS display uses emitted light, compared with reflected light for the paper chart, ECDIS must switch to a negative image of the chart at night, using a dark background in place of the white background of the paper chart, in order not to impair night vision. Three predefined different colour schemes are therefore provided: •
Day (white background)
•
Dusk (black background)

Official ENCs Nomenclature Each official ENC is identified by an 8 character identifier e.g. FR 501050. The first two characters indicate the producer e.g. FR for France, GB for Great Britain (a complete list of producer codes is included in the IHO standard S-62). The third character (a number from 1 to 6) indicates the navigational purpose band (as shown in the table above).The last 5 characters are alpha- numeric and provide a unique identifier. Updating ENCs In principle the generation and distribution of regular updates uses identical organizational structures as for the production and distribution of ENCs described above. Their frequency is usually synchronized with the chart corrections promulgated with national Notice to Mariners for the affected sea areas. Updates may reach the ship via different ways depending from the capabilities of the service provider and the communication facilities onboard: •
On data distribution media, e.g. CD;
•
As e-mail attachment via SATCOM; and
•
As broadcast message via SATCOM plus additional communication hardware.
Main characteristics of official ENCs •
Vector data in IHO S-57 format ;
•
Are referred to WGS 84 ;
•
Issued by Hydrographic Offices or on behalf of them ;
•
Flexible visualisation provided through the Presentation Library (S-52);
•
Unauthorised changes or illegal copying is avoided by use of the S-63 protection scheme;
•
SENC delivery is an alternative distribution method of ENC content in a proprietary ECDIS manufacturer format; and
•
Regular updates are provided via data distribution media or wireless via SATCOM.
Official Raster Navigational Charts (RNCs) General principles Official RNCs are digital copies of paper charts conforming to IHO special publication S-61 Product Specifications for Raster Navigational Chart (RNC) that are issued by, or on the authority of a national Hydrographic Office. When displayed on an ECDIS screen they appear to be a facsimile of the paper chart however, they contain significant metadata to ensure that they have certain minimum functionality; e.g. a means for geo-referencing positions on the chart, automatic updating of the RNC from digital files (and the ability to show the state of correction) and the display of the RNC in day or night colours as appropriate.

As a digital copy of the original paper chart, a RNC has no intelligence and other than visually, cannot be interrogated for e.g. automatic route checking or hazard warnings; however some of these limitations can be minimized by manual user input to the ECDIS. RNC data format and production RNCs are normally produced by digitally scanning the stable color bases used in the multi-colour printing process. Unlike ENCs there is not a single accepted format for RNCs. The main formats are •
BSB (used by USA, Canada, Cuba and Argentina), and
•
HCRF (used by UK, Australia and New Zealand)
•
RNCs are designed to be displayed at the same resolution as that which they are provided. Excessive zooming in or out of the same image seriously degrades the RNC image.
RCDS allows charts of appropriate scale to be displayed; when the user wants to zoom in then a larger scale chart will be displayed and similarly on zooming out a smaller scale chart will be used; •
Orientation of the RCDS display to other than north-up (e.g. course-up or routeup), may affect the readability of chart text and symbols;
•
RNCs incorporate very similar colour palettes to the day/night colours used by ENCs. It is mandatory for RCDS to have the capability to use different colour palettes;
•
RNCs are treated as individual charts (not seamless like ENCs). However, it is possible for ECDIS to automatically load adjoining chart based on the meta data provided;
•
ARPA radar targets can be overlaid onto an RNC. It is also possible for a radar video image to be scaled to fit the RNC. Scaling the RNC to fit the radar video image is unsatisfactory as this is likely to result in a degraded chart image; and
•
RNCs include significant metadata to allow the ECDIS to make maximum use of the image. For example chart notes and tide panels may be accessed directly by the RCDS rather than the user having to scroll to the appropriate area of the chart.
RNCs maintain the horizontal datum of the paper chart from which the RNC has been derived. Mariners should understand, how the chart horizontal datum relates to the datum of the position fixing system. In some instances, this may appear as a shift in position. (Any differences will be most noticeable at grid intersections and during route monitoring). Where the difference between the local horizontal datum and WGS 84 is known, an adjustment should be automatically applied by the ECDIS. RNC updating •
Updates can be supplied as complete refreshed images or as patches (tiles or areas) that the RCDS can superimpose on the original RNC. The latter method is normally used as this minimises the amount of data to be provided;
•
Updates are provided in line with those made available for the equivalent paper chart; and
•
Most RNC services currently rely on CD as the transfer media.

Resume of main characteristics of official RNCs: •
Digital copies of paper charts geographically referenced and including additional meta-data to allow RCDS usage;
•
Familiar chart display;
•
Issued by Hydrographic Offices according to IHO S-61 Standard;
•
Most routine navigation tasks achievable on the paper chart can be accomplished with the use of RNCs in RCDS; and
•
Updates are regularly supplied in line with the paper chart.
•
IMO has issued SN Circ.207 illustrating the functional differences between ECDIS and RCDS modes, (see Annex IV).
Raster Chart Display System (RCDS) ECDIS is capable of operating in: •
The ECDIS mode when ENC data is used; and
•
The RCDS mode when ENC data is not available.
However, the RCDS mode does not have the full functionality of ECDIS, and can only be used together with an appropriate portfolio of up-to-date charts. The Mariners’ attention is therefore drawn to the following limitations of the RCDS mode: •
Unlike ECDIS where there are no chart boundaries, RCDS is a chart-based system similar to a portfolio of paper charts
•
Raster navigational chart (RNC) data, itself, will not trigger automatic alarms (e.g. anti-grounding). However, some alarms can be generated by the RCDS from user-inserted information. These can include: o
Clearing lines
o
Ship safety contour lines
o
Isolated dangers
o
Danger areas
Horizontal datums and chart projections may differ between RNCs. Mariners should understand how the chart horizontal datum relates to the datum of the position fixing system. In some instances, this may appear as a shift in position. This difference may be most noticeable at grid intersections and during route monitoring •
Chart features cannot be simplified or removed to suit a particular navigational circumstance or task at hand. This could affect the superimposition of radar/ ARPA
•
Without selecting different scale charts, the look-ahead capability may be somewhat limited. This may lead to some inconvenience when determining range and bearing or the identity of distant objects
•
Orientation of the RCDS display to other than chart-up, may affect the readability of chart text and symbols (e.g., course-up, route-up)

•
It may not be possible to interrogate RNC features to gain additional information about charted objects
•
It is not possible to display a ship’s safety contour or safety depth and highlight in on the display, unless these features are manually entered during route planning
•
Depending on the source of the RNC, different colours may be used to show similar chart information. There may also be differences in colours used during day and night time
•
An RNC should be displayed at the scale of the paper chart. Excessive zooming in or zooming out can seriously degrade RCDS capability, for example, by degrading the legibility of the chart image
•
Vessels should be aware that in confined waters, the accuracy of the chart data (i.e. paper charts, ENC or RNC data) may be less than that of the position-fixing system in use. This may be the case when using differential GNSS. ECDIS provides an indication in the ENC which allow a determination of the quality of the data
A risk assessment should be undertaken prior to authorising the use of ECDIS in the RCDS mode for primary navigation. •
The risk assessment will depend upon a vessel’s physical dimensions, hydrostatic characteristics and area of operation and must address risks to own ship, other ships and environment resulting from ECDIS -related navigation hazards
•
The assessment should ensure all hazards have been identified and a system to manage the risks associated with those hazards has been successfully established onboard
Vessels should be guided by the “MCA Marine Guidance Note MGN 285 (M+F) Electronic Charts The Use of Risk Assessment Methodology When Operating ECDIS in the Raster Chart Display System (RCDS) Mode” when conducting the Risk Assessment. Meeting Carriage Requirements with ECDIS Only a type approved ECDIS operating with up to date official ENCs and with appropriate back up may be used to replace all paper charts on a vessel. Where official ENCs are not yet available, IMO regulations allow Flag States to authorize the use of official raster charts (together with an appropriate folio of paper charts) – see section below. In all other cases the vessel must carry all paper charts necessary for its intended voyage. In order to replace paper charts, such systems must fulfil considerable technical requirements: •
The chart data in use must be official (i.e. official ENCs where available);
•
The graphic display on the screen must meet the equipment-independent specification; and
•
The equipment must support the full range of navigational functions that can be performed on the traditional paper charts.

ECDIS Carriage Requirements – Summary
Acceptance of ECDIS by Port State Control Ships arriving at a port may be subject to port state control by local officials based on flag state regulations and international agreements. The port state control Officer (PSCO) will assess whether a ship is using electronic charts in accordance with SOLAS requirements. Checks may include whether: •
The ship has documentation indicating that the system complies with IMO Performance Standards for ECDIS. In the absence of such documentation, the PSCO should seek confirmation from the Flag State that the system does meet the statutory requirements;
•
The system is being used for primary navigation. It should be established if ECDIS is used in the ENC mode or RCDS mode or in both modes;
•
There are written procedures onboard the vessel for using ECDIS;
•
The master and watch-keeping Officers are able to produce appropriate documentation that generic and type-specific ECDIS familiarization has been undertaken;

The charts used for the intended voyage are the latest official editions;
•
The charts in use are updated; and
•
There are approved back up arrangements available to ensure a safe transfer of the ECDIS functions in the event of ECDIS failure and to provide safe navigation for the remaining part of the voyage.
Masters should verify that that the above conditions are met, where applicable, and should contact the Marine and HSSEQ Department for any clarifications or non compliance related to the same.
28.3
OPERATIONS
ECDIS charts provided on board are a combination of ENC, wherever available, and RASTER charts. The inventory of ECDIS charts provided on board covers the vessels current trading area. Should the vessel require an ECDIS chart in addition to that already supplied, a requisition must be made and the office informed by email providing details of the chart and reason for the request. At all times ECDIS charts must be maintained fully corrected, using the latest Notices to Mariners .On ships fitted with ECDIS where correction data is received electronically through Electronic chart correction systems, this must be used for updating the ECDIS whenever a new correction is received. Charts can be corrected by weekly updates received via email or by update CDs received at regular intervals. The procedure for updating will vary with the manufacturer and the provider of the Electronic Charts. Prior using ECDIS for appraisal and passage planning, the following checks should be carried out: •
The vessel’s controlling operational parameters (maximum draft, air draft, turning data, minimum under keel clearance required, ?look ahead? distance etc.) should be entered;
•
The GPS position system input should be set to WGS 84 datum
•
The alarm functions of the ECDIS should be fully operational; they will alert the operator to any dangers exposed in good time during the voyage
•
The electronic chart coverage for the voyage must be adequate
•
The electronic charts must be fully corrected for the intended voyage
During passage planning, marking and highlighting of electronic charts should be carried out in a similar way to paper charts. Such marking should identify radar conspicuous targets, no-go areas, parallel index lines, transit marks, clearing bearings, etc •
It is prudent for a simulated passage to be run prior to the vessel’s departure to ensure that the route does not enter any alarm preset danger areas that may have been overlooked;
•
Estimated positions should be marked on the chart for each watch, in advance.
•
Frequent checks should be made of the ECDIS position fixing system (normally GPS) by the use of other means. Such checks should include:

OMD Document No. 028 Electronic Chart Display and Information System (ECDIS)
o
Data input from the gyro compass, speed log, echo sounder and other electronic equipment to the ECDIS should be periodically monitored to ensure accuracy
o
Full functionality of ECDIS cannot be achieved when operating in the Raster Chart Display (RCDS) mode. Therefore the system should be operated in ECDIS mode unless only raster data is available for the sea area
o
Extreme caution should be exercised whenever information layers are removed or information level is reduced from an ENC and must be reviewed by the Master. All members of the Bridge Team must be advised whenever such changes are carried out.
ECDIS : Passage plans for the voyage Checks are to be made to verify that the proposed courses as laid down on the paper charts are transferred accurately to the ECDIS ensuring both systems indicate identical tracks. Where information, such as vessels position is obtained from ECDIS, this must be cross- reference with and alternative and reliable source. Users must be aware of the potential errors and limitations of the positions provided based on the different horizontal datum in use, specifically those in use in producing the ENC Vector chart, the paper chart equivalent and WGS84 from satellite derived positions. Safe operating parameters, cross track error limits, warnings and alarms etc., are to be configured as per the Masters specific instructions. Verification of these settings are to be included in the normal hand-over procedures of a navigational watch. Care should be exercised when considering which information may be deselected and eliminated from the display. Electronic updating / correcting of ECDIS charts are to be conducted with care and records maintained in a similar manner to the procedures in use for paper charts. Masters ensure that officers are conversant with the limitations and potential dangers of over reliance on ECDIS and are familiar with the general operation of this equipment before it’s use. This may be achieved by referencing operational manuals and self-tutorials installed in the equipment. Consideration should be given at changes of personnel to ensure that the operation of the ECDIS is demonstrated to newly joined officers to enable continuity.
ECDIS - Voyage Planning Voyage Planning is different on an ECDIS compared to a paper chart. There are a number of available features, such as safety contours, alarms, click-and-drop facilities for waypoints and markers, etc. While it is still possible to make errors in Voyage Plans (VPs) they are likely to be different in type from the errors most frequently observed on paper charts. Consideration should be given to developing a “best practice” for ECDIS VPs. Issues such as which chart types are available in the ECDIS for the segments of the voyage should be considered. The process analysis should also cover the situations where vessels are operating ECDIS in addition to traditional paper charts, where VPs are drawn on paper charts as well as programmed on the ECDIS. The VP format should be considered. The existing formats in use may not have been drawn up with ECDIS in mind, and a VP format produced by the ECDIS may not fulfil the needs of the company.

Voyage Planning Considerations In preparation for voyage planning, a wide array of information must be reviewed and considered. The following is a list of some items the officer in charge of voyage planning might consult: •
Appropriately-scaled charts, navigational publications such as notices to mariners, and nautical publications
•
Waterway characteristics, navigational obstructions, bar crossings and water depths
•
Institutional knowledge of areas to be transited from previous voyages (may be taken from previous voyage plans developed by fleet vessels),
•
Characteristics, condition (including engineering conditions), and operational limitations of the vessel
•
Applicable local regulations, including Vessel Traffic Services (VTS), tug escort or assist services, and pilotage requirements, etc.
•
Predicted weather, current, tidal, wind, swell, and visibility conditions along the route
•
Vessel traffic patterns and areas of expected high traffic density
•
Internal and external communication procedures and requirements
•
Vessel operations which require additional searoom, such as ballast exchange or pilot embarkation, anticipated watch conditions, and Company’s regulations such as ships’ routing schemes and reporting systems
Voyage Planning Elements A comprehensive voyage plan will include details marked on the appropriate charts (paper or electronic) as well as voyage planning forms(TSM 001) provided by TSM under their Safety Management Manuals and consistent throughout the company’s fleet. The voyage plan should include all details as specified below and HSSEQ /Operation Manual/OPS Document No2. •
Planned track with true course and distance of each leg, plotted out on appropriately-scaled charts (if an electronic charting system is used, the appropriate waypoints should be entered in the system and checked by another individual)
•
Safe speed for each leg of the passage, taking into account navigational hazards, manoeuvring characteristics, and draft in relation to water depth including squat and heel effect when turning, as applicable
•
Estimated times of arrival at critical points in the plan, wheel over positions, as applicable
•
Turn radius for each alteration, as applicable
•
Areas to be avoided where the vessel is restricted either by local regulations (i.e., marine sanctuaries) or restricted due to water depth or local dangers
•
Areas covered by local regulations such as VTS, tug escort or assist services, and pilotage requirements
•
Areas with high traffic density and/or ferry crossings

•
Areas considered to be pilotage waters where the Master, an area license holder, or a Pilot should be on the bridge
•
Areas where it is considered that the engine room should be at an increased state of readiness
•
Navigational marks to use when navigating visually near a waypoint indicating an alteration of course
•
Method and frequency of position fixing, including primary and secondary alternatives
•
Contingency plans for emergencies including abort points for port, channel, and/or berth approaches, and actions to take to place the vessel in deep water or proceed to a port of refuge or safe anchorage
Safety contour in use When using ECDIS for voyage planning, the navigation officer should establish a “safety contour” around the vessel to fully use the automated function of ECDIS. The safety contour function of the ECDIS allows the mariner to choose a depth contour (isobath) from the database to be emphasized and associated with a variety of available alarms. If the ship crosses a safety contour or approaches a prohibited or specially-defined area such as a traffic separation zone, ECDIS will automatically indicate the error while the route is being planned and executed. Due to the complexity of the system, navigation officers should receive training on the vessel’s specific ECDIS system with annual refresher training. Approval of Voyage Plans Validating a VP made on an ECDIS is different from validating a paper chart based plan. The plan may also have to deal with issues such as the planned settings of the equipment and the alarms. It requires a different mindset to review a paper plan than it does to review a plan made on a computer. It is comparable to the difference between reading a complex paper on a PC compared to reading papers in hard copy. Planning and validation of the route has therefore to consider issues such as which chart types are available for the various segments of the voyage. The format of the voyage plan is likely to differ from the traditional alphanumeric lists of waypoints used with paper charts and should include information on the usability of connected electronic navigational devices such as GPS/GNSS and AIS and their actual alarm settings. It is essential to make use of the in-built automatic check functions provided by ECDIS when validating and approving the voyage plan. Consideration also needs to be given to ensuring that a backup to the voyage plan on the ECDIS is available in case of equipment failure of the ECDIS itself or the connected sensors. Communication between the Officers/Bridge Team Voyage Plan presentation or communication to other Officers must also be considered. Once a VP has been prepared and approved it should be communicated to the other Officers. The communication of the VP will in many ways be similar to the approval. However, it is an issue, which requires separate attention to ensure that all bridge Officers are properly prepared for the intended voyage. This should include information on equipment status and backup procedures. Communication of the VP could cover the presentation to the bridge Officers at the beginning of the voyage as well as the Officer’s review of the part of the voyage likely to be sailed during a watch.

Sharing of Voyage Plans VPs may be stored and shared between several users or ships. It is possible for an Officer with a few keystrokes to print and present a complete and comprehensive VP – possibly made for a vessel with different characteristics. VPs can be sent ashore for approval or for the creation of a VP database. Although the sharing of VPs may be economically attractive, there may be legal and other considerations
Other Procedural and Organisational Considerations Voyage execution The voyage execution impacts on various bridge procedures, and the consequence of the new procedures introduced with the ECDIS should be analyzed and appreciated. It concerns e.g. issues such as the changing of the watch and the settings of the equipment and additional systems and sensors. At the beginning of the voyage, as well as at any change of watch, the officers should review the voyage plan and agree the selected pre-settings of functions, alarms and indicators to be used on the ECDIS When both paper charts and ECDIS in use Where vessels carry an ECDIS or ECS in addition to paper charts (standard navigational charts), in those situations the role of the ECDIS and the charts should be considered. If the ECDIS is used for real time navigation, the statutory requirements regarding monitoring of the progress of the voyage and marking of positions should be considered: •
Are positions marked in paper charts solely for record keeping purposes?
•
What steps are taken to ensure that intended tracks marked on the paper charts correspond with the ECDIS information?
•
Have the bridge procedures set in place by the shipping company been adapted for the use of ECDIS and are all persons concerned with the navigation familiar with these adaptations?
•
Are all persons concerned with the navigation of the vessel using the same equipment according to the bridge procedures?
Until all the world is covered by ENCs, it is most likely that most vessels to some degree will have to operate a dual – or triple – system with paper (SNC, Standard Navigational Charts), raster(RNC, Raster Navigational Charts) and vector (ENC, Electronic Navigational Charts) charts. Change of watch It should be possible for the Officer taking over the watch to look through the intended track on an ECDIS in preparation to take over the watch at the same time as the equipment is in use for manoeuvring in confined water or in dense traffic conditions. Considerations should include: •
The degree of details regarding the settings of the equipment to be covered in handing over the watch
•
The amount of time to be allocated to the change of watch

•
The considerable number of possible settings on an ECDIS which often requires that a range of sub-menus are called up
•
Whether the verification of settings above impacts on the availability of the system for navigation purposes
Standard ECDIS Settings Consideration should be given to which ECDIS settings shall be dictated by the bridge procedures, and which settings should be left to the Officer to decide upon. For most settings the degree of freedom and the level of authority should be considered, for instance in relation to the following items: •
statutory requirements
•
corporate procedures and guidelines
•
Master’s standing orders
•
VP recommendations
•
Officer of the Watch preferences
•
day or night
Position Fixing The Master is responsible to establish effective safe navigation procedures on board vessels under his command and that all available means of position fixing methods for various stages of voyage have been defined including primary and secondary alternatives. Various phases of passage plan should be evaluated in regards to the available means of position fixing methods and radar conspicuous objects should be highlighted on the charts and navigational officers should use at least two means to ascertain the position whenever and wherever possible. Visual cross bearings should be taken wherever possible. Duty Officers should be aware that it is potentially navigationally unsafe to place absolute reliance on any one electronic navigational tool. Voyage plans must contain necessary instruction in regards to position fixing methods which must be fully observed and followed. Additionally, the Master should carry out random checks against the approved and agreed voyage plan to ensure compliance. T&P Corrections on ECDIS Not all Government Hydrographic Offices (GHO) issue T&P NMs for their ENCs. Where this is the case, relevant GHO paper Notices to Mariner Bulletin or Websites (if available) should be consulted.—reference NP100 The Mariner’s Handbook Ninth Edition 2009, Chapter 2.94, par. 5. Chapter 2.87 to 2.105, focuses on ENCs. The Mariner’s Handbook states that the two systems (ENC & Paper charts) should not be compared as to most of the time the ENC system will lag and be a little bit left behind in terms of updating. This does not necessarily mean that the T&P correction will not appear in the next few updates, however if they are contained in the updates, they will automatically install on the ENC. T&P corrections will be automatically installed provided that the system is sequentially updated by the base CD’s, weekly CD’s and website downloads.

Not all ECDIS system are fitted with a date start and date end or period start, period end feature. Since T&Ps are corrections with expiry dates, some of these corrections when applied will not be cancelled by themselves; hence another remark, in exchange of the actual plotting of the T&P’s, the Cautionary areas or “Grey areas” in the ENC’s contains text of the actual T&P promulgated for the paper charts. The sequence of installing corrections is also one of the reasons why T&P’s may not be applied even if they are contained in the updates. Base Cd’s, weekly CD’s and internet updates are all necessary to be in sequence and of the latest issue to have an updated system, if the updating is out of sequence, the subsequent updates will not be loaded or will create an error in the system.

ECIDS MANDATION
Fitting of ECDIS will become mandatory in a rolling timetable that begins in July 2012. The Legislation will be phased by vessel type and size to eventually apply to almost all large merchant vessels and passenger ships. The following diagram determine which of our fleet vessels will be affected and when.
The timetable for new builds is based on the date the vessel’s keel is laid. Existing vessels are required to fit ECDIS in advance of the first survey after the implementation date. There are no requirements for existing cargo vessels of less than 10,000 gross tons. Flag States may exempt vessels that will be taken permanently out of service within two years of the implementation date.

1. The purchase and installation of ECDIS equipment We are liaising with the owners in regards to the purchase and installation of ECDIS equipment across the fleet, suggesting them the best equipment for meeting the operational and training requirements. Factors being taken into account are •
New builds
•
Existing ships
•
Training
There is large range of ECDIS equipment available, from those that are part of an integrated bridge system, through to small standalone units that could be more appropriate for retrofit to vessels that have limited bridge space. The IMO standards require that vessels must carry a backup to ECDIS that can take over the chartbased navigation functions in event of system failure. The fitting of a second ECDIS or the carriage of paper charts are widely accepted as back-up that will meet requirements. Depending on the Flag State, other solutions such as the carriage of a Chart Radar or other type-approved electronic backup may be accepted. Dual or Single ECDIS •
Dual – reduce the requirement for paper charts
•
Single – carry and maintain existing paper charts
Thome, along with the owners will need to decide whether to fit vessels with single or dual ECDIS systems. Fitting a dual system will allow a significant reduction in the paper charts carried (in some cases down to zero). If using paper charts as a back-up to a single ECDIS you are likely to require the carriage of a full (or only slightly reduced) folio. Taking all the factors into account, Thome’s aim is to have the most suitable ECDIS equipment available to suit the purpose
2. Amendment of Bridge procedures We are also in the process of further amendment of the Bridge procedures in order to include the ECDIS as navigational equipment. Ship / type specific guidelines are required to be developed in order to guide the Navigating Officers in regards to the operational capability and requirements of the equipment
3. Selection of a chart service Obtain official charts •
Ensure charts are official and compliant
•
Keep them up to date with the latest Notices to Mariners (NMs)

TRAINING – WHERE AND HOW CAN ECDIS TRAINING BE ACHIEVED
Training is a key element in the successful and safe transition to electronic navigation. Flag States normally, as a minimum, require that ships officers attend an approved generic ECDIS operator training course based on the IMO standard model. In addition, the ISM Code requires that ships officers have familiarization training for all safety equipment fitted onboard. This requirement can be met through type specific training provided by the ECDIS manufacturer. Unlike the paper chart, ECDIS is a highly sophisticated system which, besides the navigational functions, includes components of a complex, computer-based information system. In total, the system includes hardware, operating system, ECDIS software (kernel and user interface), sensor input interfacing, electronic chart data, rules for presentation and display, status and parameters of alarms and indications, etc. All these items are accessed through an appropriate human-machine interface. As such, care must be taken when navigating with ECDIS to avoid •

As with any type of shipboard navigation equipment, it can only be as good as those who use it and what it is being used for. In the case of ECDIS and electronic charts, if the mariner is well trained then the system provides the information flow that the mariner needs to make good decisions and therefore contributes significantly to safe and efficient navigation. Stated another way, an electronic chart system is another tool to enable mariners to perform their job better. However, just having some “knowledge” about “functions” and “operational controls” is insufficient to maximize the benefits of ECDIS; proper training is absolutely necessary.
Training objectives The overall objective of ECDIS training is to enhance navigation safety. In rather general terms, this includes •
•
•
•
Safe operation of the ECDIS equipment o
Use of navigational functions of route planning and monitoring
o
Proper action in case of any malfunction
Proper use of ECDIS-related information o
Selection, display, and interpretation of relevant information
o
Ambiguities of data management (“datum”)
o
Assessment of alarms and indications
Awareness of ECDIS-related limitations o
Errors of displayed data and their interpretation
o
Real and potential limitations
o
Over-reliance on ECDIS
Knowledge of legal aspects and responsibilities related to electronic charts o
Awareness of the status of ECDIS and ECS; of official and non-official data
o
Limitations of RCDS mode
In order to achieve these objectives, the mariner must acquire a thorough knowledge and functional understanding of the basic principles governing ENC data, its proper display in ECDIS and its use with navigation sensors and their respective limits. ECDIS training must have the necessary depth in theoretical aspects (ECDIS data and their presentation) as well as dealing with its proper use (functions and limitations). It should cover all safety-relevant aspects and go far beyond type-specific “button pressing” or basic operations. ECDIS training should be both generic and type-specific. Ideally, the training should cover the full extent of functions and procedures necessary to deal with a wide range of possible navigational problems. It should cover thorough route planning and both visual and automatic route monitoring in typical navigational situations and sea areas. To prepare a user for practical operations, decision-making and alarm handling, real-time complex ECDIS simulator exercises should be conducted. The IMO Committee on Standards for Training and Watch-keeping (STW) approved a standardized IMO “Model Training Course on the Operational Use of ECDIS” (Model Course 1.27). The primary objective of the Model Course is to ensure proper use and operation of ECDIS in terms of a thorough understanding and appreciation of its capabilities and limitations. The IMO Model Course contains four main parts: CONTROLLED

Ship’s Staff The following specific guidelines are for the crewing department to ensure that existing officer assigned to the vessel on “ECDIS” mode as primary means of Navigation or officer new to the company joining these vessel or new to these vessel meet the below training standards. These needs to be completed prior any employment on board Thome Managed vessels which is on “ECDIS” mode as primary means of Navigation. If further clarification is required then Director, Marine & HSSEQ, Marine Manager and/or Training Manager can be contacted. •
The IMO Model course 1.27 (The Operational Use of the ECDIS) is the absolute minimum for generic training. The timetable for the course is for 40 hours training over a 5 Day period. Any existing deck officer joining a vessel with ECDIS as primary means of Navigation should have attended the 40 hour training.
•
A training mode on the actual equipment where by type specific familiarization is completed prior joining such vessel. The training to be a minimum of 12 hours. This training presently is being held at our Thome Zadar office where Raytheon and SAM electronic ECDIS are fitted. The SAM ECDIS is also available in Thome Singapore.
•
If for reason shore based familiarization training cannot be completed then the following option to be considered prior the officer taking over the 1st watch: o
Self Familiarization of equipment with the aid of user manual and a company generated and approved checklist identified within the Bridge procedures.
o
Instruction on the vessel by a suitable experienced and able bridge officer.
o

This is to introduce the Company’s recognized ECDIS Familiarization training. The TSM Form required to be completed as a part of “company generated and approved checklist identified within the Bridge procedures” is TSM Form 065F All Navigating Officers onboard Vessels fitted with an ECDIS ( whether the ECDIS is a primary/ secondary or just for reference) are required to complete the familiarization as per TSM 065F VIQ 4.24 4.24 If the vessel is equipped with an Electronic Chart Display and Information Systems (ECDIS) are the Master and deck watch keeping officers able to produce appropriate documentation that generic and type-specific ECDIS familiarisation has been undertaken? Notes: Each deck watch keeper must be in possession of an ECDIS certificate of training. Training must have taken place at an establishment approved by the Flag Administration, address the subjects set out in, and follow the same timetable contained in the IMO Model Course 1.27, The operational use of Electronic Chart Display and Information Systems (ECDIS). If the equipment on board is a different type (manufacture) to which the generic training was undertaken, then evidence of familiarization of the actual equipment fitted on board should be provided. Record in other comments the nature of and duration of such familiarization. All Masters on board vessel with ECDIS are required to complete this for all deck officers and send same to Marine manager / Marine Supt in-charge. The completed checklist should be available to be shown on board to the vetting inspector. If he still happens to give an observation then you must add a comment as the requirement is that this can be either done ashore or on board.

LIMITATIONS OF ECDIS
The electronic chart should not be totally relied upon or lead the Watch Officer into a false sense on safety and security. Over-confidence must not result from the fact that the ship’[s position is automatically shown on a chart. The Watch Officer must be always wary as to how the system is actually performing in regard to accuracy and reliability. This requires an awareness of the deficiencies and risks of the overall system and its components. It must be recognized that the quality of the sum of the information is essentially dependent on the reliability of the each component of data and technology. Similar to any system, an ECDIS is not infallible. It has the same shortcomings that exist in any technical device. The following factors should be considered, when using ECDIS •

GENERAL
What is Sea Ice Sea ice is simply frozen ocean water. It forms, grows, and melts in the ocean. In contrast, icebergs, glaciers, ice sheets, and ice shelves all originate on land. Sea ice occurs in both the Arctic and Antartic. In the Northern Hemisphere, it can currently exist as far south as Bohai Bay, China (approximately 38 degrees north latitude), which is actually about 700 kilometres (435 miles) closer to the Equator than it is to the North Pole. In the Southern Hemisphere, sea ice only develops around Antartica, occur as far north as 55 degrees latitude. Sea ice grows during the winter months and melts during the summer months, but some sea ice remains all year in certain regions. About 15 percent of the world’s oceans are covered by sea ice during part of the year.
Why is sea ice so important and why do scientists study it? Sea ice occurs primarily in the Polar Regions, it influences our global climate. Sea ice has a bright surface, so much of the sunlight that strikes it is reflected back into space. As a result, areas covered by sea ice don’t absorb much solar energy, so temperatures in the Polar Regions remain relatively cool. If gradually warming temperatures melt sea ice over time, fewer bright surfaces are available to reflect sunlight back into space, more solar energy is absorbed at the surface, and temperatures rise further. This chain of events starts a cycle of warming and melting. This cycle is temporarily halted when the dark days of the polar winter return, but it starts again in the following spring. Even a small increase in temperature can lead to greater warming over time, making the Polar Regions the most sensitive areas to climate change on Earth. Sea ice also effects the movement of ocean waters. When sea ice forms, most of the salt is pushed into the ocean water below the ice, although some salt may become trapped in small pockets between ice crystals. Water below sea ice has a higher concentration of salt and is denser than surrounding ocean water, and so it sinks. In this way, sea ice contributes to the ocean’s global “conveyor-belt” circulation. Cold, dense, polar water sinks and moves along the ocean bottom toward the equator, while warm water from mid-depth to the surface travels from the equator toward the

poles. Changes in the amount of sea ice can disrupt normal ocean circulation, thereby leading to changes in global climate. Too much or too little sea ice can be a problem for wildlife and people who hunt and travel in Polar Regions. In the Arctic, sea ice can be an obstacle to normal shipping routes through the Northern Sea route and Northwest Passage.
What is the difference between sea ice and icebergs, glaciers, and lake ice? The most basic difference is that sea ice forms from salty ocean water, whereas icebergs, glaciers, and lake ice form from fresh water or snow. Sea ice grows, forms, and melts strictly in the ocean. Glaciers are considered land ice, and icebergs are chunks of ice that break off of glaciers and fall into the ocean. Lake ice is made from fresh water and freezes as a smooth layer, unlike sea ice, which develops into various forms and shapes because of the constant turbulence of ocean water. The process by which sea ice forms is also different from that of lake or river ice. Fresh water is unlike most substances because it becomes less dense as it nears the freezing point. This difference in density explains why ice cubes float in a glass of water. Very cold, low-density fresh water stays at the surface of lakes and rivers, forming an ice layer on the top. In contrast to fresh water, the salt in ocean water causes the density of the water to increase as it nears the freezing point, and very cold ocean water tends to sink. As a result, sea ice forms slowly, compared to freshwater ice, because salt water sinks away from the cold surface before it cools enough to freeze. Furthermore, other factors cause the formation of sea ice to be a slow process. The freezing temperature of salt water is lower than fresh water; ocean temperatures must reach -1.8 degrees Celsius (28.8 degrees Fahrenheit) to freeze. Because oceans are so deep, it takes longer to reach the freezing point, and generally, the top 100 to 150 meters (300 to 450 feet) of water must be cooled to the freezing temperature for ice to form.
Can you drink melted sea ice? New ice is usually very salty because it contains concentrated droplets called brine that are trapped in pockets between the ice crystals, and so it would not make good drinking water. As ice ages, the brine eventually drains through the ice, and by the time it becomes multiyear ice, nearly all of the brine is gone. Most multiyear ice is fresh enough that someone could drink its melted water. In fact, multiyear ice often supplies the fresh water needed for polar expeditions. Sea ice is classified by stages of development that relate to thickness and age. Most scientists describe sea ice only by its age, typically as first-year or multiyear. However, some experts who chart the extent of ice for navigational purposes use specific terms to relate the thickness of ice to its age. New ice is a technical term that refers to ice less than 10 centimetres (3.9 inches) thick. As the ice thickens, it enters the young ice stage, defined as ice that is 10 to 30 centimetres (3.9 to 11.8 inches) thick. Young ice is sometimes split into two subcategories, based on colour; grey ice (10 to 15 centimetres, or 3.9 to 5.9 inches thick) and grey-white ice (15 to 30 centimetres, or 5.9 to 11.8 inches thick). First-year ice is thicker than 30 centimetres (11.8 inches), but has not survived a summer melt season. Multiyear ice is ice that has survived a summer melt season and is much thicker than younger ice, typically ranging from 2 to 4 meters (78.7 to 157.5 inches) thick. Processes that effect the growth and melt of sea ice are referred to as thermodynamics.

Due to the dynamic nature of the ocean, sea ice does not simply grow and melt in a single place. Instead, sea ice is constantly moving and changing location.
Degree of Winter Difficulty: Ice winters are classified as “mild,” “normal”, and “severe”. The main factor in assessing the total degree of severity of an ice winter is the extension of sea ice. Other conditions affecting shipping are taken into account including the duration of the ice period, the navigability due to wind and current conditions, etc. The degree of severity within limited areas may differ from the total degree of severity. During an ice winter classified as mild, for instance, the ice conditions in the Gulf of Bothnia may have been normal.
Ice Formation Ice comes in many shapes and sizes. As it forms, a thin sheet of ice called grease ice appears on the surface. It looks a bit like a grease slick. The ice thickens in areas to form small pancake shapes. As the small pancakes come together they form larger pancakes, and so on. Ultimately what forms is a network of large pancakes making up the pack ice. As the pack ice moves with the water pieces often hit each other creating small mountains of ice from the impact, a buckling effect. Often you will see in these buckled areas what is called blue ice. When ice forms from saltwater the salt seeps out into the water below so that what is left is freshwater-ice. When the light filters through the buckled areas the ice appears blue. When large pieces of an ice shelf or a glacier break off into the sea icebergs are formed. Two-thirds of the berg remain underwater. The biggest iceberg on record was 208 miles by 60 miles, bigger than some small countries. Icebergs usually last several years before melting as they drift northward.
Ice Movements Sea ice does not simply grow and melt in one place. Sea ice is almost continually in motion, except in coastal regions where ice grows out from, and stays attached to, the shore (fast ice). The motion of ice results from a balance of forces defined by Newton’s Second Law: Force = mass * acceleration The five principal forces acting on sea ice are described below, in order of their general importance. 1)
Wind
2)
Ocean Currents
3)
Coriolis Force
4)
Internal Ice Stress
5)
Sea Surface Tilt
Wind – is the primary force responsible for ice motion, particularly at the timescale of days or weeks. The wind blowing on the top surface of the sea ice results in a drag force on the ice surface and cause the ice to drift. The amount of the force depends on the speed of the wind and the characteristics of the sea ice surface. A rough ice surface is affected more by the wind than a smooth surface. The relationship between wind and sea ice drift is so strong that a general guideline can be applied; sea ice that drifts freely moves at 2 percent of the wind speed. The directionality of free drift depends on the size of the sea ice moving; larger pieces of sea ice move at the higher range of 20 to

40 degrees to the right (Northern Hemisphere) or left (Southern Hemisphere) of the wind direction. Other factors can also contribute to sea ice free drift, but this simple relationship explains up to 70 percent of sea ice motion on a daily to weekly basis. Ocean Currents – An ocean current force typically acts in the opposite direction of the wind force and acts as a drag on the wind-driven sea ice motion. Currents are an important factor in longer-term (monthly to yearly) ice motion. In some instances and regions, currents are important even short periods of time. Coriolis Force – The Coriolis force causes objects to accelerate because of the rotation of the earth. The Coriolis force is small at scales of tens to hundreds of kilometers, but it does affect processes that occur at the global scale, such as ocean currents, winds, and ice motion. In the Northern Hemisphere, the Coriolis force causes objects to deflect to the right, and in the Southern Hemisphere, objects deflect to the left. The Coriolis force barely exists at the equator, and because the force increases toward the poles, it plays an important role in determining sea ice motion. Internal Ice Stress – is a measure of the compactness, or strength, of the ice. Among the five forces affecting ice motion, internal ice stress is the most variable. Like the ocean current force, internal ice stress usually acts as a resistance to the motion caused by the wind force. Under circumstances when the sea ice pack is loosely compacted and can flow freely (for example, during summer), the internal ice stress is minimal. When the ice is compact and cannot flow, the internal ice stress can be high. For example, where there is a strong onshore wind, we might expect ice motion to be significant; however, if the strong wind is pushing thick, compact ice toward a shore, there may be little or no motion at all, because the ice has nowhere to go. Internal ice stress also plays an important role in the deformation of the ice and in the formation of some features, such as ridges and leads. Sea ice is relatively susceptible to tension forces. So, when the ice is “pulled apart” (picture a tug-of-war game) by winds or currents from opposite directions, the ice easily fractures and forms lead. Sea ice is much stronger under compression forces. When ice is pushed together by converging winds or currents, the internal ice stress keeps the ice from moving together, but if the ice is pushed together hard enough, the ice will “fail”, or break apart, and pile up into ridges. This is similar to putting a thin piece of wood in a vise; if the vise is tightened enough, the wood fails and shatters into splinters. The strength of ice depends primarily on its thickness. Thin ice breaks apart easily under compression, while thick ice is much stronger. The failure of sea ice and the formation of ridges can create piles of sea ice many meters thick-much thicker than the thermodynamic equilibrium thickness. Thickness is one reason that thermodynamics alone does not determine ice thickness. Internal ice stress also depends on brine content, temperature, density, and other factors. Because internal stress varies so much, it is difficult to accurately estimate ice motion without it, particularly in constrained or enclosed areas of ocean. Furthermore, perhaps due to its great variability, internal ice stress remains the least understood sea ice force and continues to be a subject of considerable research. Sea Surface Tilt – Despite how it looks, the ocean surface is not perfectly flat. Even if the ocean were completely at rest, it would consist of high and low regions caused by small differences in gravity; this undulating surface is called a geoid. However, because the ocean is never completely at rest, the ocean surface is higher that the geoid in some regions and lower in other regions. Several factors contribute to differences in the ocean surface level, including uneven heating, salinity variations, and currents, especially near coastal regions or ice shelves. Differences in surface level result in sea-surface tilt, a force that influences the ice motion.

This force is quite small compared to wind and current forces and is not important over periods of several days. However, over longer periods of months or years, sea-surface tilt can have a noticeable effect on sea-ice motion. Since humans first ventured into the ice-covered oceans, they knew that sea ice motion occurred on small scales, such as a few kilometres (a couple of miles). But it wasn’t until the voyage to the Arctic that scientists finally confirmed that sea ice also moves across large-scale regions, primarily from the wind. The wind-driven Arctic ice circulation pattern has two primary components. First, the Beaufort Gyre is a clockwise circulation in the Beaufort Sea, north of Alaska. This circulation results from an average high-pressure system that spawns winds over the region. A second component is the Transpolar Drift Stream, where ice moves from the Siberian coast of Russia across the Arctic basin, exiting into the North Atlantic off the east coast of Greenland. Sea ice that forms or becomes trapped in the Beaufort Gyre may circulate around the Arctic for several years. Sea ice that forms or becomes trapped in the Transpolar Drift Stream generally leaves the Arctic more quickly, usually in one to two years. Because of this, sea ice in the Beaufort Sea has more time to grow and reach the thermodynamic equilibrium thickness, so it is thicker. Also, because of the circular rotation of ice in the Beaufort Sea, ice floes frequently bump into each other. Ice deformation is common and leads to thicker and more ridged ice compared to other regions. The Transpolar Drift Stream pushes some ice against northern Greenland and the Canadian archipelago; the ice compresses and deforms into ridges, resulting in the thickest ice in the Arctic. In both the Beaufort Gyre and Transpolar Drift Stream, most of the ice follows a large-scale pattern when considered over a long period of time; however, within this long-term pattern of movement, there can be a great deal of variation. For example, the Beaufort Gyre may completely reverse directions and often does for short periods of time, such as after a storm from a low-pressure system that moves across the region. Likewise the Transpolar Drift Stream may also reverse direction. Antarctic: The Antarctic large scale circulation of sea ice is generally in a clockwise direction around Antarctica, with gyres, or smaller rotations. There is an average northward component, so sea ice gradually moves to the northern ice edge after it forms. In the arctic, land encircles much of the sea ice, constraining its flow, resulting in ridging and thicker sea ice. The overall flow of Antarctic ice is quite different. There is no northern land boundary for the northward flowing sea ice to run into, so the ice flows northward until it melts in warmer oceans and air temperatures. Because of this, Antarctic sea ice is younger and thinner, on average, than ice in the Arctic. Most sea ice in the Antarctic is less than a year old.
Ice Bergs Icebergs, often known as bergs or bergies, generally range from 1-75 meters (about 3-246 feet) above sea level and weigh 100,000 to 200,000 metric tonnes (about 110,231-220,462 short tons) The tallest known iceberg in the North Atlantic was 168 meters (about 551 feet) above sea level, making it the size of a 55-story building. Despite their size, the icebergs of Newfoundland can move up to seven kilometres (about four miles) a year, making them among the fastest moving icebergs in the world. These icebergs originate from the glaciers of western Greenland, and may have an interior temperature of -15 to -20 degrees C. (5 to -4 F)

Shape: In addition to the above size classification, there is also a type of classification based on shape. The two basic types of iceberg forms are tabular and non-tabular. Tabular icebergs have steep sides and a flat top, much like a plateau, with a length-to-height ratio of less than 5:1. Non-tabular icebergs have different shapes, and include. •
Dome: An iceberg with a rounded top.
•
Pinnacle: An iceberg with one or more spires.
•
Wedge: An iceberg with a steep edge on one side and a slope on the opposite side.
•
Dry-Dock: An iceberg that has eroded to form a slot or channel.
•
Blocky: An iceberg with steep, vertical sides and a flat top. It differs from tabular icebergs in that its shape is more like a block than a flat sheet.
An Iceberg is a large piece of freshwater or water ice that has broken off from a snow formed glacier or ice shelf and is floating in open water. 3

Since the density of pure water ice is ca. 920 kg/m , and that a sea water ca. 1025 kg/m , typically, only one ninth of the volume of an iceberg is above water. The shape of the remainder under the water can be difficult to surmise (imagine) from looking at what is visible above the surface. This has led to the expression “tip of the iceberg”, generally applied to a problem or difficulty, meaning that the visible trouble is only a small manifestation of a larger problem. The word iceberg is a partial loan translation from Dutch ijsberg, literally meaning mountain of ice, cognate to Danish Isbjerg, Swedish Isberg, Low Saxon Lesbarg and German Eisberg. Iceberg calved from the Ross Ice Shelf. Though usually confined by winds and currents to move close to the coast, the largest icebergs recorded are calved, or broken off from, the Ross Ice Shelf of America. Icebergs come off the Upsala glacier. Lago Argentino, Santa Cruz, Argentina. When an iceberg melts, it makes a fizzing sound called “Bergie Seltzer.” This sound is made when compressed air bubbles trapped in the iceberg pop. The bubbles come from air trapped in snow layers that later become glacial ice. Monitoring: Icebergs are monitored worldwide by the U.S. National Ice Center (NIC), established in 1995, which produces analyses and forecasts of Arctic, Antarctic, Great Lakes, and Chesapeake Bay ice conditions. More than 95% of the data used in its sea ice analyses are derived from the remote sensors on polar-orbiting satellites that survey these remote regions of the Earth. The NIC is the only organization that names and tracks all Antarctic Icebergs. It assigns each iceberg larger than 10 nautical miles (18 km) along at least one axis a name composed of a letter indicating its point of origin and a running number. The letters used are as follows: •

SEAFARING IN WINTER CONDITIONS
Preparation for Entering Ice: Arrival to Ice Covered Areas When the temperature drops under zero degrees Celsius during winter, icing can cause big difficulties. The vessel must in good time take measures so that water and steam pipes on deck and spaces which are not warmed up should be emptied. The layer of ice grows continuously and this can lead to problems with stability of the vessel, especially on smaller vessels. During the voyage, it is immensely important to know what kind of ice-conditions can be expected on the basis of the ice-report and the route recommendations which have been given. In sea areas with ice situated are changes rapidly under the influence of weather, and therefore the information about ice and wind forecasts should be used to estimate which changes are going to take place. Wind is the factor which mainly causes ice to move. The speed of ice is approximately 2% of the wind speed, and the direction of the movement varies about 20-25 degrees to right. It is risky to proceed to moving ice with a vessel with a weak engine power. Most vessel have problems with cooling water intakes (sea chests) Therefore the possibilities to use ballast tanks for cooling water should be looked into. The voyage has to be planned before sailing, berth to berth.
Operating in Ice: The voyage to icebound ports can be divided in the following parts: •
Voyage planning prior to departure
•
Open sea at subzero temperatures
•
Approaching and entering the ice field
•
Independent operation in ice
•
Icebreaker assisted operation
•
Pilotage and approaching port/archipelago

Open sea at subzero temperature Before entering the area of subzero weather, at least the following precautions should be taken: •
All water pipes (and –taps) outside must be emptied, including fire lines on deck and in the holds. Compressed air can be used to make certain all the water is emptied.
•
The air pipes and sounding pipes of ballast tanks are also not water filled. Ballast tanks should be filled only to 95% to ascertain this.
•
All movable equipment not needed on deck should be stored in sheltered areas.
•
The pilot ladders should be protected from freezing.
•
Protect the anchor windlass and mooring winches with tarpaulins in case there are no fixed protections.
•
Ensure all loose mooring equipment is stored.
•
Ensure your propeller is completely submerged and as deep as possible, nevertheless excessive trim should be avoided to keep the ice within the ship’s ice belt.
•
Sea chest might get clogged, prepare to use ballast tanks for ME cooling.
•
Ventilators etc should be checked and stopped to avoid freezing of equipment indoors. Even the engine room can freeze if the fans are running full blast. Also air-condition equipment might need adjustments etc to function properly.
•
Prepare everything for icing from open sea and subzero temperature. Your windscreens and wipers will freeze quite fast if no de-icing is available. Also make sure the windscreen washing systems are emptied of water.
•
Follow weather reports to identify danger of icing.

Single Navigation in Ice Water When entering the ice area from open waters, you need to take special care and exercise caution. When the winds are blowing from the open sea towards the ice, an area of brash ice and shuga forms at the ice edge. This area can be very difficult to penetrate and behind it is mostly an area of consolidated ice and ice ridges. If you run into the shuga blindly, you might very possibly get stuck. Never run into the ice at full speed if you do not know exactly what you will encounter. Even an isolated ice floe in otherwise open waters can damage a ship severely when running at full sea speed. The ice area can vary very much. There might be level ice, consolidated ice, brash ice etc and also open stretches with no ice or very open drift ice. In general it is recommended to avoid ice ridges and try to run in level ice and use existing open leads. Follow the waypoints given by icebreaker. If you deviate from the instructions, you might make the icebreakers job much more difficult. Remember, though that you are still responsible for the safe passage of your own ship. Try to obtain advice from other ships advancing ahead of you or coming out of the ice, you might use the channels broken by them.

The safety of navigation is very important, as in these conditions you cannot follow your preplanned route. GPS sailing following a track line is simply impossible. Instead you have to plan using methods of “no-go areas. Mark those areas you can use without danger and mark the ‘no-go areas’. With continuous plot of your position you should be fairly safe. You should also remember that, in wintertime, these latitudes are covered in darkness most of the day. In northern Bay of Bothnia the length of the day at winter solstice is only about 4 hours. In the Gulf of Finland it is somewhat longer, about 6 hours. Powerful searchlights and good radars are of the utmost importance. Searchlights, in plural, because the heavy vibrations and shocks when running in ice damages the equipment quite frequently. Especially ships with forward situated bridges are susceptible to these problems. The searchlights should be as powerful as possible. Because they (and the radars) are the only means to ascertain your route through the ice. The radar is also an important piece of equipment, if properly used. Ice formations, ridges and open leads can be identified on radar, as well as the broken fairway. In this case, the x-band (3cm) radar is better. As mentioned, the shocks and vibrations can also damage other equipment, antennas. It is not unheard of the mate suddenly losing GPS position and, at the same time, a piece of equipment falls to the deck, to be identified as the GPS antenna. It is almost impossible to replace such a piece of equipment at 20 degrees below and 15m/s in total darkness. The gyro compass can be affected by vibrations, the signal is disturbed and the radar/integrated system loses input for a moment. This will cause radar to go to ‘head-up’ display. Switching back is often possible in a few seconds, but when the disturbance is repeated every few minutes, you just have to go give up and run in ‘head-up’ mode.
Proceeding in Ice When sea water starts to freeze, the ice in the open sea gets thicker. The ice-cover becomes asymmetric because of sea currents, wind and the Coriolis force. For the sake of clarity, the ice-areas have been divided into main categories according to their accessibility. The ice-classes in the Baltic Sea Code area are the following: new ice; young ice; open pack ice; close pack ice; compacted shuga; fast ice; consolidated pack ice and ridged ice or hummocked ice. The movement of ice depends on its thickness. When mild winds blow the ice thickness in the Bay of Bothnia is 40cm, and the ice moves all the time. Under harsh winds the even ice is 80-90cm thick, and therefore the ice field is not so mobile in the open sea. In the spring when the ice has started to melt and the even areas have melted completely, the rest of the hummocked ice drifts gently around. The mobility of the ice or the pressure depending on the factors mentioned earlier make the ice to get an asymmetric form. The ice piles up, is pushed into ridges and forms belts of slush and shuga, and everything changes constantly its form depending on external factors. The pack ice ridges constitute the biggest obstacles for seafaring. They consist of ice pieces or floes which are packed together over and under the water surface. The average thickness of the ridges in the Baltic Sea area has been estimated to be approximately 4m. Heavy ridges with the depth of 10-14m can be fairly frequently found in the Bay of Bothnia. Some drifting pack ice ridges have been measured to be 28m under water and 3-4m above water. When pack ice ridges come into contact with the sea bed, the height over the water can increase manifold. The ice floes in the pack ice ridges are relatively small, approximately 3 to 5 times the thickness. There are ice blocks here and they are loose. The consolidated part of the ridges is approximately as big as the thickness of the surrounding fast ice. Because the floes in the ridges are loose, a highcapacity icebreaker can assist merchant vessels during the whole voyage in winter also into the northernmost ports.

Navigation Outside of the Ice To proceed in ice from open sea requires caution and good judgment. When the wind blows from the open sea towards the ice, there is often a belt of shuga at the edge of the ice. The shuga can, depending on how strong and lasting the wind has been, turn out to be highly difficult to penetrate. Behind the shuga there is often a belt with compacted ice and with the highest probability ridges of ice. If one proceeds blindly into the shuga with full power, this can result in the vessel getting stuck and the voyage being interrupted. The main principle is that one never proceeds into shuga from open water with full engine power if one is not absolutely sure about the prevailing circumstances and the nature of ice. Especially in the spring even isolated ice floes can, due to their massive underwater parts, cause major damage to the vessel in collision circumstances even if the vessel is in no danger of getting stuck. An ice field in the sea areas varies usually a lot. It can contain fields of pack ice, areas with even is, new ice, open leads or leads covered with new ice, and areas with open water. When deciding upon the route, it is important, if possible, to avoid areas with many pack ice ridges. In general it is a good idea to try to proceed along areas with even ice and follow possible leads, even if the voyage thus becomes longer. On the other hand, if the ice field is compacted, proceeding carelessly along leads can lead to the interruption of the voyage when the leads merge if one does not at the same time follow how the situation develops and what the ice conditions in the surroundings are. Therefore one can save time and avoid damages by in uncertain situations stopping when it is dark and only proceeding in daylight. Several vessels on their way to the same direction should preferably stay together, which enables mutual assistance so that the voyage can continue even if the circumstances are difficult. When proceeding in an ice field it is usual to come across a ridge which makes continuing impossible. In order to prevent getting beset it is a good idea to closely follow the vessel’s over more slow movement forward. If it is clear that the vessel will come to a stop, a full astern with the engine is in order even before the vessel has stopped by itself. Even if the vessel does not disengage immediately, the propeller current is used to cause effect under the vessel and along the sides. When moving astern in the ice, the rudder must always be positioned midships so that the ice floes do not damage the rudder blade and the rudder stock. If a pilot cannot be taken onboard, full speed forward is taken and the rudder is moved back and forth so that the vessel would move. At the same time till the propeller current will clean the stern part from ice. If pilot boarding attempts with alternating full forward and full astern fail, attempts to eliminate static friction must be taken. The vessel should be made to move with the help of tanks or deck cranes while the engine at the same time is full astern. If the pilot boarding does not succeed despite all the efforts, an icebreaker must be informed about the vessel being stuck. To get stuck in a moving ice field with pressure signifies a noticeable risk for the vessel. There can be damages to the hull through indentations in the shell plating, damages on the frames and in the worst case there can even occur leakages. Therefore it is best to try to go astern to the arrival direction if the voyage starts to seem too difficult and the broken ice-channel begins to close behind the vessel, so that the vessel can find an easier route or a safer area with thin ice where the vessel can wait for an icebreaker in safe conditions. If the vessel is forced to wait for the icebreaker in a frozen area, the fore or aft must be turned against the wind so that the possible ice pressure against the sides is minimized. One must avoid stopping in moving ice near the coast because the ice can lead the vessel with it aground or between rocks which makes icebreaker assistance more difficult or impossible. Navigation in winter conditions requires great precision. Floating sea marks e.g. spar buoys and buoys are not there or have been stored up. Sector lights in sea lighthouses and other lighthouses can be covered with ice or snow which makes it easy to take their green or red lights as white. Because of the pack ice, the coast and ground formations differ from the chart on the radar screen. It is almost impossible to separate the radar echo of a small lighthouse from the echo the ice masses generate. Therefore the most important lighthouses have been equipped with a Racon which can usually be seen in a 3-cm radar.

Radar is an excellent instrument when navigating in an ice field, especially in dark and when the visibility is bad. A 3-cm radar gives a relatively reliable picture of the ice situation up to 3 miles’ distance from the vessel. Areas with open water, leads, ice-channels and compacted ice can be seen quite clearly. However, the interpretation of the radar display requires a lot of experience. The main principle is that even ice and areas with open water do not usually generate an echo, and therefore the echo gets stronger when the ice field gets more compacted. When proceeding in darkness, extra caution is required, especially in areas where there is a lot of open water. Collision with thick ice can damage the vessel. By continuous radar surveillance it is possible to observe obstacles in due time and either try to sail around them or, in constraining circumstances, approach the area with ice with appropriate caution. When it is dark, powerful searchlights can be very helpful in observing the ice situation in vicinity and choosing the route. Avoiding actions: •
Deviate to shelter, along coastlines (risk of grounding….) Remember updated voyage plan.
•
Reduce speed
•
Consider stopping in sheltered position
•
Preplanning imperative!
Navigation with Ice Breaker Assistance Vessel which requires icebreaker assistance must after sending a prior notice continuously be standby on the radio and notify about all the possible changes which differ from the information given in the notice to the icebreaker or the coastal station to which the latest notice has been sent to. Notifying the time for arrival to the place where the assistance will start is important – the icebreaker can work in an efficient manner and it also saves time for the vessel which will be assisted. When the vessel arrives within the reception area of the VHF, the icebreaker gives the vessel a working channel which must be constantly listened to. Preparations for Icebreaker assistance equal with the following actions: The vessel is switched to manual steering. Possible ice is removed from the windlass and the bollards in the bow. A line is placed within reach so that the thin wires of the towing line can be fitted onto the deck. In order for the close-coupled towing to succeed, the anchors must be 4.5m above the water line. To prompt memory, the information on icebreaker light-signals must be placed close to the engine controls. When the vessel stops in darkness in order to wait for icebreaker assistance, searchlights must be switched off as always when the vessel does not move. If many vessels are simultaneously assisted by an icebreaker, the expression “assistance for vessels in a convoy” is used. The icebreaker decides the order in which the vessels sail in the convoy; this order must be absolutely followed unless new orders are given. The weakest vessels are placed nearest to the icebreaker, the strongest vessel as the last one. In this way the convoy will proceed with the speed of the weakest vessel. The icebreaker decides upon the distances between the vessels, and these distances must be maintained during the voyage. In normal circumstances the distance between the vessels is approximately 0.5nm, for large vessels approximately 1nm. The icechannels which the icebreaker breaks in the open sea often close quite quickly because of the movement of the ice. Therefore the distance between the vessels should not be too long. The quicker the convoy moves and the shorter the distances between the vessels are, the less the movement of

the ice has time to affect the ice-channel. The distance is determined on the basis of the vessel’s size, draught, engine power, astern going capacity, the quality of the ice, how compacted it is, etc. In convoy assistance every vessel must carefully keep the distance to the previous vessel, and if one’s own speed decreases, the vessel immediately behind must be warned without delay. The engines must all the time be prepared to be put full astern. The VHF must not be, without an explicit permission from the icebreaker, changed over to another channel, and the vessel must all the time be ready to be towed. The orders and instructions given by the icebreaker must be absolutely followed both in convoy assistance and in the assistance of an individual vessel. If the orders and instructions are not followed, the icebreaker assistance is interrupted. The thickness of the ridges and unevenness on the ice cover often lead to a situation where the vessel in front or even the icebreaker must stop. Then there is risk of collision if everyone does not act quickly and correctly. The first measure in an emergency situation is to turn the rudder to the side where the ice seems to be thinnest. If it is not clear from the ice what one should do, turn the rudder the direction which increases the turning rate when taking astern. Simultaneously when the rudder is turned, the engine is put full astern, if it is not clear that the vessel can sail out from the broken icechannel. With the help of the rudder, it is nevertheless possible to create a situation where the bow turns against the edges of the ice-channel so that the speed stops. In that case the propeller current of the previous vessel helps the vessel to settle crosswise. If the icebreaker suddenly stops or decreases speed rapidly, the two rotating warning-lights in the stern are lit. In that case the vessels following the icebreaker must take action immediately to prevent collision, especially if no specific orders are given on the radio.
Towage in Ice If the vessel cannot follow the icebreaker either because the ice-channel is to difficult to enter of closes far too quickly, towing may be in order. The icebreaker then tows the assisted vessel either with a long cable or as a close-coupled towing. In the outer sea areas with variable circumstances and total ice cover, close coupled towing is the only useful and efficient way to tow. Then the bow of the assisted vessel is hauled using a towing winch in the stern notch of the icebreaker. It is always the icebreaker which decides when the towing will start. The assisted vessel must then immediately start preparing for attaching the towing cable. It is important to act quickly especially when there is pressure in the ice field. From the bow of the assisted vessel a towing line is thrown to the astern going icebreaker, after which two thin cables are hauled to the vessel, one on each side of the bow. The cables are attached to the windlass and the real towing cables are hoisted up and attached to the bollards in the bow. When the towing cables have been attached to the bollards, this is notified to the icebreaker, and after this everybody must clear off from the foredeck. When a vessel is being towed, the engine orders are given by the icebreaker. The rudder can be used especially in bends so that the vessel will turn more easily. The towing ends when the icebreaker deems it suitable, and therefore the assisted vessel must be able to cast loose the towing cables at any time. Towing with a long cable comes into question only when the assisted vessels are very large or equipped with a bulb stem and in general only ice-channels in fast ice. When the icebreaker assistance continues in the direction towards the port of destination, the coast gradually comes nearer and it is time to call for a pilot. Because of winter conditions, the prior notification is not always accurate, and therefore it is often the icebreaker which has to inform about the exact time of arrival. The assisted vessel must anyway make sure that the icebreaker sends the message early enough. During the winter season, the pilot boarding positions are along the fairways in places which are sheltered by the coast or by islands and cliffs. This differs from the procedure during the open water period. When icebreaker assistance is received, there are no risks when arriving to the pilot boarding position. If circumstances make it possible for the vessel to proceed to the coast without assistance, the navigation requires extreme precision. As mentioned earlier, the floating seamarks such as spar buoys and buoys have been removed, or they may be covered by ice or may have moved from their normal places. There is therefore no reason to blindly rely on them. CONTROLLED

Depending on the ice situation and the local circumstances, the pilot can come to the ship in different ways. If the pilot comes to the vessel in a steel cutter and there in no open water in the area, the vessel must stop completely so that the ice will not press the cutter under the stern of the vessel – the engine power of the cutter is often quite weak. When the pilot boarding position is located at the edge of an ice-channel in fast ice, the pilot climbs onto the vessel from the ice. In many places there is a so called ice-bridge available; it is pushed from the ice against the side of the vessel in the fairway. In that case an ordinary pilot ladder can be used. If there is no ice-bridge available, the vessel should have an ice-ladder prepared. This is a long wooden or aluminium ladder which is pushed over the rail as far to the side as possible. The upper part of the ladder must absolutely be attached to the rail. Alternatively the hoisting crane of the vessel can be used to lower a basket down to the ice. The arm of the hoisting crane is usually long enough to reach to the edge of the ice so that the pilot does not have to go on the broken ice in the ice-channel and risk falling in. When the vessel approaches a pilot boarding position located at the edge of the ice, the vessel must be manoeuvred as close to the edge of the ice-channel as possible. The pilot can also come onboard from the icebreaker. The icebreaker then gives stop orders and approached the vessel bow first in order to, using its own pilot elevator to lift the pilot onboard. The pilot can also board the vessel from a helicopter. This however requires that there is enough free space on the deck for landing. If deck structures make direct landing on the vessel impossible, the vessel must be stopped so that the pilot can safely move over from the ice to the vessel. In such cases the vessel has to have a 4-5 meter plank ready so that it can be placed out over the ice and the pilot can use it to pass the broken ice and to board the vessel using the ladder. When the vessel comes from fast ice to an ice-channel, the most dangerous part of the voyage is over, proceeding in ice in open sea. Depending on the ice qualities of the vessel and the quality of the ice-channel, the vessel can possibly proceed without icebreaker assistance. In the archipelago routes, it is often a problem to pass or meet other vessels, if only the vessel’s own power is used. Especially during such winters when the ice is thick and almost always in the northern coastal areas, the edges of the ice-channel can be so hard that not even powerful merchant vessels can come out of the ice-channel when meeting another vessel. It is also of uttermost importance that situation reports about the traffic in the ice-channel are carefully monitored. The VHF makes it possible to agree with a meeting vessel on where the passing will occur, where the fairway area is wide and the ice as easy to proceed in as possible. Overtaking may not be considered until the leading ship has been beset. A hasty attempt to overtake can make both vessels to get stuck and the ice-channel thus becomes blocked-up. When passing a meeting vessel or overtaking a vessel in front extra caution must be paid. It is very difficult to get out of the ice-channel, and therefore it is usual to combine the agreement of the rendezvous with the fact that the vessel with weaker engine power stops for the overtaking. •
If the proceeding in the ice-channel is very slow and it is only a matter of time when the vessel will get stuck, the voyage must be interrupted before the vessel gets stuck in a narrow part of the fairway. The narrowest parts of the fairway always have ice-channels where it is difficult to proceed, and pilot boarding becomes more difficult due to the lack of space. Therefore it is not advisable to sail forward using all engine power if the vessel is going to get stuck anyway.
•
In the archipelago there are so called ice roads for people living in the archipelago, and these roads intersect the fairways here and there. There are sings warning for the intersections and they are erected along the ice-channel at such a long distance that vessels have time to slow down or, when necessary, stop completely before they come to the intersection. In the intersection the icechannel must be as narrow as possible, and therefore the vessels must pass the places for intersection paying major caution and avoiding breaking the edge

of the fast ice. The same applies to the pilot boarding positions in the archipelago. •
During the winter the ice-channels in the fast ice get more and more difficult to penetrate. The icing caused by frost and the hummocking of snow make the slush and shuga get heavier. In a lively trafficked ice-channel in the spring, before the ice has started to melt, ice formation of 2m in the ice-channel and over 5m at the edge of the ice-channel have been measured. The single ice blocks are often several cubic meters. Severe frost makes the proceeding in the ice-channel more difficult because the friction increases manifold compared with proceeding in milder waters.
•
Also the mooring to a quay differs because of the ice from how it is done in open water. In order to get the vessel to the quay, the ice between the vessel and the quay must be cleared away. In general the harbour icebreaker has already broken the ice near the berth, and then one should approach the quay with an angle of approximately 20-30 degrees. The bow must come as close to the quay as possible where the stern will be moored. When the bow is close to the edge of the quay, the rudder is turned towards the quay and engine put ahead. The ice conditions have an effect on how engine power is required. In all cases the power must be adequate in order to maintain the angle to the quay so that the ice cannot come between the vessel and the quay through the bow. When the vessel has reached the berth a double spring is taken ashore and the bow and the stern are run out from the quay in turns through using the engine and rudder in such a way that the ice between the vessel and the quay is pushed / flushed away. The propeller current brings about a suction which draws out the ice.
In such cases when the harbour area is frozen and the ice has not been broken, time is often save if the vessel breaks up the ice. First the vessel is manoeuvred towards the quay at the distance of 3-4 vessel length from the berth. After that the engines are put astern and only after that the vessel sails towards the berth as described above.

4.1
MAIN ENGINE MAINTENANCE
Engine maintenance schedules must be adhered to as far as possible. Overdue items should be reported to the technical superintendent and fleet group manager as "Maintenance not done" through the reporting facilities of the planned maintenance system. Indicator diagrams or peak pressure cards will be taken monthly on all motor ships: •
Immediately after leaving dry-dock.
•
Whenever an engine defect is suspected.
Whenever main engine maintenance in scheduled in port or at anchor, the bridge must be notified to ensure the propeller is clear. Any maintenance tasks, either planned or unplanned, which renders the Main Engine inoperative for a period of more than 2 hours, has to have prior approval from the ship’s Vessel Manager or Technical Superintendent as applicable. The following procedures are to be followed: •
TSM Form 055 A – Critical Equipment Maintenance Permit is to be submitted (in MS word format) to the Office. Both Marine and Technical department are required to review, enter their comments and evaluate the request prior concurrence.
•
TSM Form 089 & TSM Form 089A (as required) should also be completed to highlight the hazards and risk control measures implemented in order to lower the risk.
•
Once the above documents have been submitted and concurrence received, the equipment can be immobilised and the maintenance carried out.
TSM Form 055A is only valid for twelve hours. For any job exceeding twelve hours a fresh TSM Form 055A is to be completed. Once the maintenance work has been completed and permit should be closed and office informed . Prior to starting any maintenance:

•
Designate the person in charge of the maintenance.
•
A safety meeting is to be held with all those involved in the tasks. Briefing on the maintenance procedures, communications procedures and any related safety precautions and contingency plans must be discussed and understood.
•
The designated person-in-charge will assess the maintenance area and carry out the necessary checks and tests after which a written Critical Maintenance Permit with a duration that does not exceed 12 hours may be issued by the Master for each intended task.
The procedures and precautions with all incorporated checks and tests are to be carried out: •
After a permit time has expired and before continuing with the intended maintenance
•
In case the maintenance has been suspended and prior to resumption of the work
This is not applicable to maintenance carryout during when the vessel is in a shipyard or during dry docking. The risk assessment must include as a minimum: •
Personnel, spares and tools
•
Worst case scenarios
•
Testing procedures
•
Necessary modification in operational procedures as a result
Cylinder Heads, Liners and Pistons The most frequent causes of fractured cylinder heads are sudden temperature changes and extreme temperature differences between combustion and cooling water spaces. To prevent cracking: •
The main engine should be warmed-through before starting
•
The main engine should be kept warm during normal port calls
•
Cooling water passages should be inspected periodically to ensure that they are clear and not obstructed by scale or by graphite accumulation
•
The cooling down procedure after finished-with-engines is important, particularly where pistons are oil cooled. The cooling oil must be circulated for at least an hour as stagnant oil in contact with hot surfaces will break down to form carbon deposits.
•
Jacket water chemical protection must be kept at the recommended levels; periodic checks should be recorded in accordance with manufacturers recommendations
•
Every precaution should be taken to prevent the main engine being started with oil or water in any of the cylinders. The main engine must be turned by turning gear or slow turning with indicator cocks open after a prolonged port stay or maintenance and turned on air prior to starting.

OME Document No. 004 Engine Room Systems
The exhaust temperatures should be monitored carefully and the cause of any sudden reduction in temperature should be investigated immediately. If water should enter a cylinder while the main engine is running, the exhaust temperature for that cylinder will show a reduction.
Valves and Valve Gear The condition of the cylinder head valves is a major factor in the correct and efficient operation of any diesel engine. It is essential therefore to chance and overhaul them on a routine basis in accordance with manufacturer's recommendations. Overhaul schedules should be monitored through the planned maintenance system
Fuel Oil and Injection System The fuel injectors and pumps are precision units manufactured to close tolerances. Care must be taken and cleanliness maintained during overhauls. Contact with rags or cotton waste must be avoided and the components must be re-assembled in a wet condition to avoid abrasive matter adhering to the parts. Other concerns include: •
Atomizer spray holes must be cleaned only with the special tool provided.
•
A correct spray pattern, release pressure and clean cut-off should be achieved when testing the injectors by means of the test pump.
•
Atomizer needles and pump plungers are ground to match their respective nozzles and sleeves and must not be interchanged.
•
To achieve correct atomization, the fuel temperature should be regulated to ensure that the viscosity at the injectors is correct. The necessary temperature can be derived from the temperature-viscosity charts which are supplied to all ships, and the injection viscosity is obtainable from the engine manufacturers' handbook.
•
Operating with too low a fuel temperature and a correspondingly higher viscosity will raise peak pressures above the safe limits.
Lubrication System The pressure and temperature of the lube oil supply must always be maintained within the builders' specification. The cleanliness of the lube oil and entire system is of primary importance and the purifier must be operated on a routine basis to maintain this condition. Water washing must only be carried out on instructions from Thome, subsequent to analysis results indicating that washing is necessary. Only distilled water may be used for this purpose.
Charge Air Systems The efficiency of turbochargers tend to fall off very slowly and it is necessary to keep a record of all temperatures, differential pressures and revolutions should therefore be closely monitored. General considerations include: •
Washing of air and exhaust ends in accordance with manufacturers' instructions.
•
Inspection of the gas inlet interceptor grids must be carried out on a regular basis to ensure freedom from fouling and damage. All accessible ports should be cleaned out at the time of this inspection. Air intake filters should be cleaned as necessary as determined by differential pressure measurements.

•
Charge air coolers should be routinely cleaned to prevent an increase in differential pressure. Cooling water supply to the cooler must also be regulated to maintain the air temperature just above dew point.
•
Supercharged and under-piston spaces should be regularly examined and cleaned. Examination should include air transfer valves where fitted.
Crankcase An examination of the crankcase should be carried out at monthly intervals. Inspection should include: •
The testing of all bolts for tightness, together with their locking devices.
•
Camshaft driving gear, including spray pipes; the supply of lubricant to all bearings and spray pipes should be checked while the turning gear and lubricating oil pump is in use, prior to closing.
•
Examination of the piston rod sealing is to be made periodically and at every piston change to ensure that the scraper rings bear uniformly on the rods, that the oil drain holes from the stuffing boxes are quite clear and that the rings are clean and floating in their cages. Piston Telescopic seals should also be regularly inspected.
•
Use of intrinsically safe lights and the adherence to smoking regulations in the vicinity of an open crankcase.
Precautions for Overheating of bearings Overheated bearings can lead to an oil mist explosion in the crankcase. The following precautions must be observed to reduce the risk of crankcase explosion:
4.2
•
Early detection of overheating and the prompt slowing or stopping of the main engine may prevent the occurrence of conditions conducive to fire or explosion.
•
Should an oil mist be detected, the crankcase or inspection doors must not be opened until the main engine has cooled down. The main engine should not be restarted until the cause of overheating has been established and rectified.
•
The oil mist detector must be tested and proven operational at intervals specified by the manufacturer. Testing should be incorporated in the planed maintenance system.
MAIN PROPULSION – STEAM TURBINE
Warming and Shutdown Procedures The warming of steam turbines must be carried out in accordance with the maker's instructions. Appreciable distortion can occur in both the rotors and casings during this process, and also during cooling down periods, if the rotor is allowed to remain stationary for any length of time. The turbine rotors should never be allowed to remain stationary for longer than five minutes, while steam is supplied to the glands, to prevent local heating stresses occurring in the area of the gland pockets of the stationary rotor. The propeller rotation required is negligible, and one or two rev/min will ensure satisfactory rotation of the turbine. The propeller shaft must not be turned until it is established by the bridge that the propeller is clear. The gland steam system must be operated in accordance with the manufacturers' recommendations to minimize gear case humidity.

Maximum Power Underway Full power should be made as soon as steady conditions permit. The plant should be adjusted to provide the maximum efficiency under prevailing conditions. A comparison of the temperature and pressures obtained with those specified in the Heat Balance Diagram will give an indication of efficiency. Temperatures and pressures must therefore be kept as close as possible to the system specifications.
Reduction Gearing The gears and flexible couplings should be regularly inspected for wear or deterioration. When inspection covers are removed, great care must be exercised to ensure that nothing falls into the gear case. Naked lights must not be used due to the danger of explosion.
Lubrication system The condition of the bearings is dependent on an adequate supply of clean lubricating oil. The purifier is to be run on a regular routine basis, for at least 7 days in every 10, to remove any water or sediment. Lube oil filters must be in use. If oil starvation has occurred after a lube oil failure, an examination of the bearings and gearing should be carried out before returning the turbine to service. Where a lube oil gravity tank is fitted, the run-down valve must be locked open at all times when the main turbines are turning. Gravity tank alarms and emergency main turbine trip valves should be checked at regular intervals. Lubricating oil usage must be monitored and recorded daily.
Safety Devices The operation of all governors and trip devices must be checked and proven at intervals not exceeding one month. This is extremely important and must not under any circumstances be neglected. The over-spend governor cannot normally be tested whilst the ship is in service and an item covering the examination and testing should be submitted at repair periods/dry-dock.
4.3
WATER TUBE BOILERS
Feed water System and Chemical Treatment Particular attention must be paid to the purity of feed water of high pressure water tube boilers. Distilled water only must be used and this must be chemically tested to ensure that it is suitable before use and results recorded. If de-mineralization columns are also used, the outlet conductivity must not exceed normal limits or regeneration of the de-mineralisation column may be required. In general, full heating steam should be maintained to the de-aerator under all conditions of plant operation. This will ensure that the de-aerator design shell pressure and outlet feed water temperature are maintained. Most oxygen should then be removed from the feed water, provided there is no leakage of air into the condensate system, and that the de-aerator air release system is operating correctly. Residual traces of oxygen can then be removed by hydrazine or sodium sulphite treatment. Engine department personnel must be familiar with the chemical testing and treatment of the feed water. Chemicals should be added in accordance with manufacturers recommendations and suppliers instructions. Chemical tests of the feed water are to be made daily, and the results entered in the Engine Log. Continuous monitoring of condensate is to be carried out by means of the salinometer, the operation of which must be regularly tested. The results should be tabulated on the record sheet for monthly reporting. Boilers must be blown down weekly where possible to remove sludge accumulations, and when the total dissolved solids concentration limit is exceeded. It is preferable to blow down under light load conditions and when possible, the opportunity to do so should be taken when in port. A single blow, using the drum blow down valves should normally be sufficient. Where water-wall header drain CONTROLLED

valves are fitted, the system must only be blown down on light load. When blowing down in port, care should he exercised if the ship's side valve is above water and craft are alongside. The valves must be opened for a very short period only. In case of oil contamination of boilers a stock of chemicals sufficient to degrease each boiler twice must be carried on each ship. The efficient operation of water gauges is essential. Personnel concerned with boiler operation should routinely confirm that water gauges are fully operational. Low water alarms and trips must also be regularly tested and should be included in the planned maintenance system. Remote level indicators must be considered to be aids only and their readings must be frequently checked against the direct mounted master water gauges. In the event of water falling or rising below the visible range of the water gauge, the following course of action must be taken: •
Extinguish the burners immediately
•
Closing the feed check valve
•
Close the steam stop valves
•
Maintain steam flow through the superheater by opening the vents
•
Stop the forced draught supply after a full purge
•
Add water only when the boiler has cooled sufficiently to prevent water coming in contact with overheated pressure parts
Combustion System and Operation Efficient combustion is dependent upon the fuel being completely burned with the minimum amount of air. To achieve this, the fuel must be injected into the furnace in a finely atomised state of even pattern mixed with the correct quantity of heated air. The atomisation and spray pattern are dependent on the viscosity and pressure of the fuel, condition of the burner and atomising steam temperature and pressure, while the air quantity and mixture will depend on the regulation of the fan dampers. Certain ships are provided with continuous excess oxygen analysers which are valuable aids to achieving minimum air and complete combustion, but care should be taken to ensure readings are unaffected by forced draught air leakage through casings. To atomise correctly, the fuel requires to be at a required viscosity when being injected. The necessary temperature to achieve this viscosity can be obtained from a temperature viscosity chart. It is important that this temperature is checked at the fuel delivery rail to the boilers and not at the heaters, as considerable heat loss can take place between these two points. When changing burners, suitable receptacles are to be used for collecting any spillage of oil. The cleaning, handling and inspection of burners must be carried out with great care. The atomiser holes should be tested regularly and examined to ensure that they are not enlarged, distorted or damaged. Under exceptional circumstances, boiler fires and naked lights in the engine room may be prohibited, and the master must always inform the Chief Engineer of the precautions necessary when these circumstances prevail. The danger arising from particles of incandescent soot being discharged from the funnel can be minimised by operation of the soot blowers on a routine basis at sea and also by operating the soot blowers as close before entering port as permissible. Care must be taken when lighting a boiler fire by hand. The furnace must be purged through with air beforehand for at least 3 minutes on maximum draught. Should fuel be admitted before the insertion of the igniters or torch, it may vaporise in contact with hot surfaces and when ignited, result in a blowback and serious injury. CONTROLLED

The engineer in charge of the watch must be present before the boilers are lit up and when raising steam, no engineer of a rank more junior than that of fourth engineer may be left in charge. The following checks must be carried out before lighting up: •
That the gauge glass cocks are in the correct position.
•
That the water level is correct i.e. there is a level showing at about 50mm from the bottom of the glass.
•
That the superheater vents are fully open to allow steam to circulate through the superheater elements and that they remain open until the boiler is in service.
•
That the superheater drains are open to remove any water that may have lodged there and which would evaporate leaving solids.
•
That the economiser tubes are full.
•
That there is no accumulation of un-burnt fuel on the furnace floor.
If the vessel is fitted with automatic purging, the purging sequence must be completed and on other vessels the furnace must be thoroughly blown through before any attempt is made to flash the boiler. When the boiler is flashed on a volatile fuel such as gas oil, particular care must be taken that purging is complete. Fuel must not be allowed to pass into the furnace after an unsuccessful light-up attempt. Where possible, steam should be raised using the air heater, in order to even out warming-through. Steam or air atomisation should be used in preference to pressure jets. Steam atomising is not permitted when gas oil is being used. The use of limiting devices such as gags or wedges which restrict the complete closing of fuel valves is strictly prohibited. The safe practice of adjusting the master controller set point to reduce the boiler working pressure under port and maneuvering conditions should be observed. When navigating in close waters, the auxiliary boiler should be fired for one-minute intervals to test the fuel oil and combustion system periodically, say once per day. The uptake temperature where gas/air pre-heaters are fitted should not be permitted to drop below the dew point to avoid the dangers of corrosion. Under full load conditions, the uptake temperature should be regulated to maintain it above the minimum of 166°C and under light loads, gas preheaters, where fitted, should be completely bypassed.
Pressure Vessel Relief Devices It is important that all relief devices fitted to any pressure vessel operate correctly, as the consequences of failure could be disastrous. In particular, relief valve waste pipes must be proven clear and unrestricted. The Chief Engineer shall instigate a routine inspection programme to ensure that waste pipes and drains of all pressure relief devices are correctly fitted and unobstructed.
Boiler Maintenance It is important to stress the attention any boiler requires and the dangers of neglect. The direct attention of Chief Engineers is required to ensure boiler feed water, boiler treatment, blow down and in particular all safety devices are being correctly cared for and regularly checked. Also that their staff have clear, preferably written instructions in this respect which they clearly understand. The firesides of the tubes should normally remain clean, with good combustion and the regular use of soot blowers and other fitted devices. However, faulty combustion or a defective soot blower can

lead to serious slagging and fouling. Continued operation under these conditions may result in serious damage to the boiler. Infraphones, where fitted, should be frequently checked to ensure that they are operating correctly and every effort should be made to return them to service following failure. The condition of the fireside of the tubes should be examined at intervals or when the boiler performance indicates a fall off in efficiency. Every boiler must be shut down for examination and cleaning as necessary or at regular intervals as indicated in the instruction book. Permission must be obtained from Thome, before any boiler is shut down for routine maintenance, if this affects charter speed for the voyage. The opportunity should be taken to remove soot deposits and to clean the tubes, also to check the soot blowers and repair any defects, paying particular attention to the blowing arcs and the condition of the blower nozzles. Water washing will usually be found to be the most effective method for the removal of slag deposits but should not be done unless absolutely necessary. A gentle but plentiful application of fresh water, as hot as possible, and at least 76°C through a suitable lance, should loosen and wash away the slag. A fire should be flashed up as soon as possible using a small size burner tip to dry the refractory. Salt water must not be used under any circumstances for water washing boilers or steam generators. There is little danger of major corrosion, by acid attack, taking place during the period of a normal inservice clean when the boiler would be expected to be off-line for 48 hours. Major corrosion could occur should the boiler be shut-down with wet refractory for an extended period. Water washing must therefore be avoided prior to an extended shut-down in excess of 48 hours. Should washing be unavoidable, prior to an extended shut-down, the refractory must be dried out using the forced draught fan and air heater or fired until dry. The refractory should be carefully inspected and repaired as required. Casings should be repaired as necessary and doors must be refitted correctly. Particular emphasis must be placed on the cleanliness of the economisers when washing and when blowing tubes. All safety precautions must be observed when firing and when washing. Junior engineers and crew must be supervised in order to maintain adequate safety standards. All low level trips, both level switch and transmitter actuated, must be tested monthly. The operation of the fuel valves must be checked at the same time. The test detail must be entered in the Engine Log. When tubes have been renewed, care must be taken to remove all traces of the oil which is used when expanding the tubes. In the case of an extensive renewal of tubes it is necessary to boil out the boiler to remove the oil. Where pneumatic hacksaws are supplied to ships they are specifically for cutting out otherwise inaccessible tubes. They should be treated with care and not used for any unauthorised maintenance work.
Boiler Lay Up The method of laying up a boiler will depend on the conditions likely to be experienced. The wet lay up method must be adopted for very short lay ups only. The method to be adopted will be advised by TSM.

To lay up a boiler wet, it must be completely filled with distilled water which has been chemically treated to bring the alkalinity up to a maximum of 300 ppm. All air should be allowed to escape through the superheater vent. A pressure of 3.5 bar should be raised hydraulically and maintained until the boiler is at engineroom temperature. The superheater vents should then be tested to ensure that no air remains. It is then essential to establish that there are no leaks.
Soot Blowing at Sea Boilers are to be sootblown every day or depending on actual condition of boiler when firing on fuel oil. When firing on gas only soot blowing can be reduced to every third day. Boilers to be soot blown before entering port, regardless if fired on fuel or gas. The dual fuel burner registers are fitted with pneumatically operated air sleeves and igniters. The atomising steam, fuel gas valves are also fitted with pneumatic actuators. Steam is the normal atomising medium when burning heavy fuel oil: air is used for starting up and when burning distilled fuel. Oil burners that are not firing are cooled by maintaining the atomising steam supply. The burner oil passages are automatically purged with steam from the atomising supply whenever they are extinguished. When firing on gas only hot fuel is circulated through the boiler oil headers so that the oil burners can be ignited instantly when changing to dual fuel or oil only firing. The firing will automatically change from gas only to duel fuel should the cargo tank pressure fall below a pre-set limit (fuel oil back up) or to fuel oil only (fuel oil boost up) if the master gas valve closes. There is no automatic boost up when an individual boiler gas valve trips. It is important that all oil burners are fitted in place and ready to be lit when burning gas only. All manual fuel oil and atomising steam valves on the burners and in the supply lines must be open. The burners are each fitted with 6 gas spouts. Three of these have multi-hole nozzles where gas must mix with the air outside the nozzle before it ignites (external mix). The three other spouts are arranged with an internal gas nozzle about 400 mm from the end of the spout. This nozzle acts as an ejector and sucks air into the spout through openings adjacent to the nozzle. The air and gas will therefore pre mixed (internal mix) in the spout before it leaves through the single opening in the nozzle at the end. The gas spouts have alternating internal and external mix spouts equally spaced round the periphery of the impeller. This arrangement ensures even distribution of air to the oil and gas flames, stable flames and good ignition of the gas flame over the whole load range.
Soot Blowing in Port Soot blowing is not to be carried out when vessel is within port limits.

ELECTRICAL SYSTEMS
Safety Precautions All electrical conductors, installed in electrical equipment on board should be assumed to be live until they are isolated from all power sources. A test meter, suitable for the normal rated voltage should be used to prove the circuit is dead after isolation, before maintenance work on the circuit may proceed. It is recommended that the correct operation of meters be proved by testing on a live circuit immediately before and after being used to prove an isolated circuit. No tests should be applied to live main switchboard busbars. The circuitry within panels, motor control centres and starters, control enclosures and other equipment may be supplied or energised from more than one source at more than one voltage. Special care is needed to isolate effectively such circuitry before maintenance work may proceed. Where it is necessary to work in the vicinity of live conductors, an insulating non-slip mat should be used as floor covering. This protection is mandatory on switchboards. Rubber soled footwear should always be worn when working on electrical equipment and the use of electrician's rubber gloves and insulated tools is recommended. Clothing must be dry. The load must be isolated before fuse links are re-inserted into a circuit. Electrical apparatus must be maintained in good condition to ensure efficient operation and to afford maximum protection against shock to the operator. Insulated control handles, knots or dials, e.g. on galley range equipment, must be replaced by exactly similar items made of the same material. In certain applications where 440 volt supplies are used, control knobs or handles are of insulated design to ensure safety to personnel. It is important to ensure that portable electrical equipment with a metallic outer case has a secure earth connection. Equipment with worn or damaged flexible cables must not be used. The maintenance of cargo clusters, electric drills, and old types of hand lamps are frequently neglected. Earth connections must be checked frequently for continuity and the cable entries at plug and equipment must be inspected frequently for chafing and wear. Portable equipment should be fed from outlets supplied by isolating transformers unless no such supplies are available on board. Any voltage should be regarded as capable of producing major injury or loss of life by electric shock. The Ship Captain's Medical Guide, Chapter 1, should be referred to for treatment of victims of electric shock.
Operation and Maintenance The electrical generating and distribution systems differ in manufacture, type of equipment and configuration, between ships. Instructions for this particular equipment must always be followed. Where emergency diesel generators are referred to, these machines conform to the following minimum classification requirements: •
The generator is situated above the uppermost continuous deck.
•
The generator is situated outside the machinery space.
•
The fuel and cooling systems are self contained.
•
Two independent starting methods are provided.

OME Document No. 004 Engine Room Systems
The generator can provide power for the following services simultaneously: o
Emergency lighting, navigation lights and daylight signalling lamp.
o
Emergency diesel-generator sets should be tested regularly for starting on power failure and coupling automatically to the emergency switchboard. All diesel-alternator sets should be tested regularly on full load.
o
Batteries for starting purposes should be kept charged. Air receivers and fuel tanks should be kept full.
Where two identical alternator sets are fitted they should be changed over at intervals not exceeding 1 month in order to maintain the insulation, governors and bearings in good condition. In steam ships which are fitted with one main turbo-alternator and one diesel-alternator of the same capacity, the turbo-alternator will be in service for much longer periods than the diesel-alternator. The alternator heaters must be switched on in the diesel-alternator and also the emergency diesel generator in order to maintain the insulation in good condition when these machines are not in use. These machines must also be turned regularly. The main alternator sets are designed to run in parallel for all conditions of loading and any instability should be investigated and rectified. In order to ensure that the sets are capable of satisfactory load sharing, they should be left in parallel for approximately four hours on each change over. Inability to operate satisfactorily in parallel must be regarded as an operational defect and Thome must be notified. When on standby conditions, a main alternator must be kept running at operational speed, synchronised with the first alternator and supplying a share of the load. Diesel-alternators are to be equally loaded and must not be allowed to run unloaded for more than a few minutes. All standby equipment including motors, feeder cables, steering supplies, etc., should be changed over with running equipment at regular intervals. Heaters, where fitted, should be switched on in standby electric motors.
Battery Systems Batteries must be maintained carefully in accordance with the manufacturers instructions. Battery rooms must be adequately ventilated to prevent build up of concentrations of hydrogen gas. Where automatic equipment is installed to supply emergency lighting circuits on failure of power to the switchboards, these circuits must be tested weekly.
Hazardous Area Installations All installations in hazardous areas must be maintained in good condition. Flameproof equipment, in particular flameproof lighting fittings, must be maintained in a safe condition and the Chief Engineer must arrange for the replacement of unserviceable equipment. Enclosure covers must be secured as specified by the manufacturers. Failure to observe these requirements will destroy the effectiveness of the enclosure and allow the external propagation of flame resulting from an internal ignition. Intrinsically safe installations usually use zener barrier devices to separate parts of circuits which are installed in hazardous areas from parts which are installed in safe areas. Their function is to limit the electrical energy which may be transferred to the parts of the circuit which are installed in the hazardous areas under fault conditions. The energy limit is selected to ensure that an explosive mixture present in the hazardous area cannot be ignited. CONTROLLED

The barrier units are sealed and must not be opened. Testing must be confined to replacing a suspect unit with an identical spare. No other maintenance action may be permitted. Warning: test meters must not be connected to the wiring on the hazardous side of the barrier. The Electrician should also be instructed to inspect all explosion proof electrical fittings on the cargo deck of each tank ship and to remove or clean any Silicone sealant applied and replace only the original O-Ring gasket so that the fittings are installed as designed. A prohibition to the use of Silicone on the cargo deck is to be included in the Electrician’s hand-over notes.
Dry-docking Precautions Heaters, where fitted to motors, alternators, switchboards, etc., should be switched on throughout the dry-docking period. The actual operation of the heaters should be checked during the first day of the dry-docking period. Heating lamps can be fitted to all motors not fitted with heaters, at the superintendent's discretion. Regular insulation tests should be carried out on motors to ensure that a safe level is maintained, before any motors are started after the refit period.
Earth Faults and Insulation Testing Earth indication lamps are located on all switchboards and certain sub-switchboards. Action must be taken as soon as possible to locate and clear an earth fault as soon as indication has been given by the lamps. Failure to clear one fault may result in failure of supply to equipment and risk of fire or other damage to the electrical installation should a second fault occur on another phase of the same system. Galley equipment, lighting fittings and domestic consumers are more prone to earth faults than large engine room motors. If an earth fault is traced to a motor circuit the possibility of the fault existing in the motor control gear is likely and should not be overlooked. The more modern ships are provided with earth fault monitoring relays and the relays should be tested regularly. 500 Volt high voltage insulation testers of the Megger type or similar are supplied to ships and these should only be used to test equipment connected to medium and high voltage. High voltage insulation testers must not be used on alternator rotor or exciter windings which are rated for low voltage operation. Rectifiers and other semiconductor devices are also incorporated in this equipment and the application of a high reverse voltage would cause serious damage to these devices. High voltage insulation testers must not be used on any part of electronic control circuits. As a general rule, all motors not fitted with operational heaters should be tested prior to starting after a prolonged shut-down period.

Microwave Ovens - Inspection and Testing Microwave ovens, supplied to ships, comply with the various statutory regulations and British Standard requirements. They are provided with basic safeguards designed to contain the microwaves and reduce any emission or leakage to safe levels. These include door interlocks, effective door seals and overload and no-load protection (to safeguard against overheating and switching on when the oven is empty). The equipment must be maintained in good order and microwave ovens should be inspected and tested at regular intervals.
Maintenance of Intrinsically Safe Equipment The integrity of the protection afforded by the design of intrinsically safe electrical equipment may be compromised by incorrect maintenance procedures. Even the simplest of repair and maintenance operations must be carried out in strict compliance with the manufacturer’s instructions in order to ensure that such equipment remains in a safe condition. This is particular relevant in the case of explosion-proof lights where incorrect closing after changing a light bulb could compromise the integrity of the light. In cases where the manufacturer’s instruction are not located or understood, or in case of any doubt, the vessel manager is to be contacted promptly, before any maintenance can be commenced.

5.1
PLANNED MAINTENANCE SYSTEM
Maintenance of machinery and equipment must always be based upon the manufacturer's instructions, where maintenance procedures and intervals are specified. Maintenance routines must be planned to prevent machinery failure as a result of an oversight in scheduled maintenance. Most Thome vessels will implement a computerized Planned Maintenance System with a database of maintenance jobs to be scheduled. For this purpose, the Thome usually employs the following as a company standard: •
AMOS-D
•
AMOS For Windows
Other systems for planning maintenance may however be utilized in certain circumstances as deemed acceptable to management and in accordance with the instructions from the technical superintendent. In all cases, maintenance intervals for all critical and essential items must be specified. Overdue items should be reported to the technical superintendent and fleet group manager as "Maintenance not done" so that shore based personnel may follow-up and provide resources when necessary. Changes must only be made to the system after discussion with the ship's Fleet Group Manager, Superintendent and, for computerized systems, the software instruction manual. The following guidelines should be adhered to: •
When the planned maintenance system indicates that a particular machine or item is due for attention, all routine maintenance such as greasing, oil changes, filter cleaning, etc., should automatically be done and the work recorded.
•
The Chief Engineer does not have the discretion to alter the frequency of planned maintenance schedules without confirmation and agreement from the Fleet Group Manager and Superintendent
•
If a machine has had abnormally low running hours since the last routine maintenance, the Chief Engineer may postpone part or all of the tasks to a later date, but must report the job as maintenance not done.
•
Where the planned maintenance system indicates that a major overhaul is due, the Chief Engineer should verify if there has been any deterioration in

REGULATION OF SPARES & STORING
Both engine and deck departments must ensure that adequate spares are kept in case of breakdown of essential machinery or equipment and for routine use in scheduled maintenance and repair activities.
7.2
•
A list of essential spares should be established based upon class recommendations and in consultation with the technical superintendent
•
Spares for critical equipment are listed in the AMOS database for each critical equipment
•
A minimum safety stock should be kept for critical spares, and in some cases also others, depending on availability and cost of storing. The superintendent should be consulted before setting the safety stock level.
STOWAGE OF SPARE PARTS
When received, spare parts should be checked, labelled, and stowed in the correct position in the spare part stores. Particulars are to be entered into all sets of records kept on board. •
All machined and all polished surfaces of spare parts are to be fully protected against corrosion. Where parts are clamped to the bulkhead or ship's side, corrosion may occur underneath the clamps. Spare parts are to be stowed so that it is available for inspection at all times. Used spares must not be stowed as spare parts unless they are in good condition throughout and are completely serviceable for further use and marked as such. Rubber components, such as valve diaphragms and large seals, deteriorate if not stored correctly. They should be coated with French chalk and laid out flat in a cool, dark place. It should also be noted that when storing metal parts, adding a dehumidifier bag would be an advantage, and should to the extend possible be pursued.
•
A record is to be maintained of spare parts withdrawal and the chief engineer advised to enable updating of inventories and processing of requisitions.

Vessels had to fit new genuine coalescers and only then released from detention. This incident is obviously a serious violation of MARPOL regulations, for which ship managers and/or crew members can be fined a large amount of money or even be arrested. Preventive measures suggested are: •
The ship manager should supply genuine parts.
•
The ship manager should supply a certificate of genuine parts issued by a manufacturer if available.
•
The crew should check genuine parts to be used.

MAIN ENGINE MAINTENANCE
On arrival at any port or anchorage the main engines must not be immobilised without the consent of the master, who must ensure there are no port regulations prohibiting this and that it is safe to do so. For his part, the Chief Engineer must advise the master of how long he expects the main engines to be immobilised and the maximum time required to make the engines available should there be an emergency or change of orders while immobilised. Risk Assessments (Informal or Formal) must be performed FOR ALL JOBS and a Formal Documented Risk Assessment on form TSM 089 and JHA on form TSM 089A must be performed and Office must be advised in accordance with SHE Manual Doc16.7(Maintenance and/or shutdowns of critical equipment). Any maintenance on main engine control systems should only be carried out when the engine is clearly inhibited from starting and with the full knowledge of both master and chief engineer. Main engine turning gear should be engaged for the entire period that cargo hoses or chicksan arms are connected or, in the case of bulk carriers, when cargo loaders/unloaders are working. Turning gear should also be engaged when the bridge is unmanned. At all times when the turning gear is disengaged, procedures must be adopted to prevent inadvertent starting of the main engine. All engineers must be aware of how the main engine may be tripped in an emergency and, where trips are fitted on the bridge, deck officers must be familiar with their position and when they are to be used.
Underwater Operations Prior to any underwater inspection of the hull and propeller, a full briefing should be conducted by the members of the management team onboard and with the diving contractors when they arrive on the ship. The officer nominated to attend to the divers must be made aware of the value of video inspection. Main engine turning gear must be engaged when divers are working beneath the ship, and the main engine may be turned using the gear provided the divers are advised. No equipment should be started or any operation commenced that will cause an appreciable underwater disturbance and divers should be briefed as to where they will encounter disturbance from sea water inlets and discharges. In all cases, a permit to work must be issued prior to commencement.

OTHER MACHINERY TESTS
Main Engine When it is necessary to run the main engine in port for trial purposes, and the sanction of the port authority, has been obtained, the Master is to ensure that the ship is adequately moored, all cargo hoses are disconnected and that the propeller is clear. The Master in consultation with the Chief Engineer will determine the speeds at which the engine can be safely operated.
Steering Gear In addition to normal pre-arrival and pre-departure tests, should maintenance work be carried out on the remote control system, the steering gear should be tested to ensure that the rudder moves in the correct direction.
Clock Synchronisation The bridge and engine room clocks should be synchronised prior to the commencement of any manoeuvre. If, for any reason, this cannot be done, a note is to be made in the Engine Log on completion of manoeuvres, giving the difference in time between the two clocks.
Plant Performance Trials Each ship is to at monthly intervals complete a machinery operation report.
Failure or Repair Follow-up Should any essential part of the ship's control system which has recently given unsatisfactory performance or has been overhauled or adjusted since the last port should be proven operational. Such tests must be carried out in safe waters where a loss of main engine power for several hours could not endanger the safety of the ship.

ENGINE PRECAUTIONS AGAINST FREEZING Purpose To specify requirements for Engine Precautions against Freezing
Application All vessels
Responsibility Master Chief Engineer Chief Mate
9.1
PRECAUTIONS AGAINST FREEZING
Precautions must be taken to prevent damage being sustained by the freezing of water in the various services, whilst maintaining as far as is practicable the efficiency of the ship and the comfort and amenities for all on board. Although the Chief Engineer is responsible for taking precautions to avoid frost damage to all pipe systems, pumps, machinery and the chief officer for precautions with regard to cargo lines, their mutual cooperation in the forewarning of frost and the implementation of precautionary measures is required if damage and discomfort are to be avoided. Precautions against freezing will need to be taken for equipment in the engine room when temperatures there fall to near freezing point. This will only occur under dead-ship conditions or during refit in cold conditions. It should be noted that sudden changes in sea and air temperatures - are to be expected during winter months on passage from the Caribbean or Mexican Gulf to N. American ports. For example, during the passage, the ship leaves the warm Gulf Stream and enters the cold Labrador Current in the vicinity of Cape Hatteras. In this area, sea temperatures may fall from 21°C to 7°C and air temperatures may also fall sharply, in a distance of under 200 miles. Sea temperatures as low as -1°C may be experienced in the vicinity of Halifax and during December, January, February and March, air temperatures as low as -25°C may be experienced off New York and adjacent ports. •
Operations Manual Part D / OME Checklist 002 should be used

Weather forecast in affected areas should be monitored closely and due precautions taken when approaching areas where cold conditions are experienced during other winter seasons.
9.2
MAIN ENGINE – FREEZING PRECAUTIONS
In port the cooling spaces for the cylinders, pistons, turbo-blowers, etc. should be circulated with their respective media which should be heated by the means provided. Should this not be possible then all spaces containing water must be completely drained. Hand hole-doors should be removed and pipes disconnected where necessary to ensure that no pockets of water remain. The engine should be moved by the turning gear at least once a day, and during this operation the cylinders should be oiled by the hand operated gear on the mechanical lubricators.

cold zone is prolonged, a short trial run should, if possible, be taken at least once a week after the engine has been given two complete turns by the turning gear, and all precautions taken to see that the propeller is not damaged by pack ice during the process. When the presence of pack ice is suspected, the main engine should always be started as slowly as possible.
9.3
EMERGENCY DIESEL ENGINE – FREEZING PRECAUTIONS
Water cooled emergency diesel engines not fitted with heating elements should be filled with an antifreeze solution. The strength of this solution should be checked at regular intervals and adequate stocks of anti-freeze should be carried.
9.4
PUMPS – FREEZING PRECAUTIONS
All pumps that are not in use must be completely drained of water. Due consideration should be given to the possibility of their refilling through passing valves and to any anticipated requirement to return them to service quickly.
9.5
BUNKERS – FREEZING PRECAUTIONS
If fuel is carried in the forward deep tanks, all slack spaces at the after end should be topped up before the cold zone is reached to obviate transferring difficulties under freezing conditions, and also to reduce loss or contamination should forward tanks become damaged during passage through ice.
9.6
ACCOMMODATION - FREEZING PRECAUTIONS
When destined for high latitude ports during winter months, the accommodation heating system should be thoroughly inspected and all necessary repairs carried out before reaching the cold zone. If it is necessary to shut down the system after arrival, widespread freezing up will be unavoidable, and it may not be possible to get the system working again until a more temperate climate is reached.

Application All Vessels
Responsibility Master Chief Engineer Chief Mate
10.1
PLANNING FOR REPAIR SPECIFICATIONS
Dockings are a period of generally high expenditure and therefore accurate preparatory work is essential. The Chief Engineer will use TSM Form 60 Specification of Repairs to detail those items which must be deferred for shipyard repair periods. Prior to entering a repair yard it is essential that all work is clearly specified with every detail. Items that require removal such as handrails, pipes, and floor plates must be specified. Likewise the number of bolts on involved flanges and manholes, the amount of new welding and joining or where staging may be required (any work above one meter) must all be accurately addressed. Improper planning in this regard results in much higher costs as the unspecified extra work is always charged at full rate instead of the pre-negotiated discount rate. The Superintendent must be in a position to ensure work is quoted upon by the shipyard prior to the ships arrival. Unscheduled jobs in the yard must be avoided.
Supervision of Repairs When in a repair yard only the Superintendent may authorise work. During repair periods, all the ship's officers and crew will assist the Superintendent as required in the monitoring, inspection and acceptance of the work being undertaken.
10.2
SURVEYS
All the machinery, with the exception of the Boilers, Inert Gas Plant and Tail-shaft (for which special regulations are applicable) must be surveyed and passed by the Classification Society's Surveyor within a five year period. Additionally, all UMS classed vessels must adhere to an agreed alarm testing schedule, which must be kept up to date. Thome will endeavour to obtain class certification for Chief Engineers so that survey work is undertaken survey work onboard. Chief Engineers must have a certificate for the particular class of their particular vessel before undertaking surveys. In any case class must survey each component once within each five year cycle. The Chief Engineer should arrange for overhauls and inspections of various machinery items in accordance with planned maintenance. These should coincide with the ship's arrival at one of the major ports where a Classification Society Surveyor is available. The particular item or items opened may then be scheduled for survey. The Master Survey Listing should be updated and a Form TSM 68 Survey Report submitted to the Singapore office. When a survey is done by a Chief Engineer, it must be recorded in the Engine Room Log Book and a detailed report must be made. CONTROLLED

The report should contain details of the dismantling work undertaken, calibration and measurement of clearances, list of spares renewed, re-assemble and testing procedure as applicable. As far as possible, report should also include photographs. The original report should be presented to the Class Surveyor and a copy should be forwarded to the Singapore office. CSM records are to be carefully monitored to ensure there is no build up of over due items. Overdue items can affect the Owners insurance cover should a casualty occur. It should be remembered that many of the surveys undertaken by class are in fact statutory surveys on behalf of the Flag State (Safety Equipment and IOPP for example). Statutory surveys not only affect the Owners insurance but are part of international law and have legal implications for the Owner, ship's Master, officers and crew.

Precautions for Charging and Recovery of Halon (where applicable) For safe and environmentally compliant work on Halon Fixed Fire Fighting Systems: •
Halon bottles shall be delivered back to an approved Supplier (as advised by TSM) for servicing, pressure-testing, overhauling, etc., as required
•
There shall be no intentional release of Halon from the System
•
A Log is to be maintained of all Halon being handled onboard (when bottles are landed ashore for charging, pressure-testing, level or weight check onboard, etc.,) as per Form TSM 029
Management of Ozone Depleting Substances The global ban on the production and consumption of CFC's, Halons and HCFC's (herein referred to as Ozone Depleting Substances-ODS), as regulated by the 1987 Montreal Protocol, leads to a significant shift to substances with zero Ozone Depletion Potential (ODP), like for example HFC's. In order to limit the emission of ODS to the atmosphere international treaties, major Flag States and Classification Societies focus on handling of refrigeration systems in an environmental sound manner. Therefore, any service on systems containing ODS (e.g.: repairs, retrofits & conversions) requires a system that can deal with potential ODS waste in an environmentally sound manner, utilizing approved technologies for recovery, recycling, reclamation and disposal. The quality and handling of Refrigerants and Compressor Oils has an impact on the associated machinery and equipment. Poor quality of refrigerants and Compressor Oils will lead to frequent overhauls and repairs, with subsequent loss/release of ODS to the atmosphere. Precautions for Using or Handling Compressor Oils Lubricant selection for a refrigeration system is critical not only for the compressor but also to ensure that the oil does not separate from the refrigerant gas in any part of the plant. If the oil type or supply manufacturer is changed, incompatibility and hence poor miscibility within the plant can cause problems. With the wide range of mineral and synthetic products on the market, coupled with different additive technology, it is vitally important to check miscibility prior to top-up with a different grade oil. The alternative is to drain the oil completely from a refrigeration system, which can be very difficult or even prohibit the use of non-approved refrigeration oils. Used Refrigeration Oil must be disposed off properly.
Long Term Maintenance "Specification of Repairs" (Forms TSM 060 & TSM 060A) The objective of this form is to eliminate the large number of repair items that are missed out, or overlooked, during the preparation of the Docking List.

OPERATION OF THE MAIN TURBINE
The maintenance and operation routines in the company manuals are generic to the vessel types. However, it is very important that reference should be made to any maker’s recommendations that are specific to any vessel or that vessel’s main and auxiliary plant and any machinery or appliances onboard.
Warming Through Ready for Leaving Port Provided the turbines have been turning under vacuum with gland steam on for 24 hours it is possible to get underway immediately in an emergency provided due care is taken to warm through and drain the steam lines and speed is increased slowly. If any unusual vibration is detected speed should immediately be reduced and the turbines operated at no more than 25 RPM for at least 15 minutes before attempting to increase speed again. •
Check that the ahead emergency valve, ahead nozzle valves, astern manoeuvring valve are fully shut. Check also that all the turbine manual and automatic drain valves are open. All bleed and drain valve control switches should be in AUTO position
•
Drain the steam lines upstream of the intermediate stop valve
•
Gradually open the bypass valves on the intermediate stop valves until the pressure in the line to the manoeuvring valve chest is about 5 bar
The turbine will then be in normal state of readiness maintained in the port.
Getting Ready 1 Hour before Departure The Deck officer of the watch or Duty Deck Officer is to be contacted and permission to turn the turbines / propeller requested. Once the Deck Officer has confirmed that this can safely be carried out then and only then can the turbine be turned.

•
In the Engine Control room select the remote hand spinning and by manipulating the controls turn the engine ahead and astern taking care not to open the valves too far
•
Continue turning ahead and astern (maximum 5 RPM) (10 RPM for NGSCO ships) at frequent intervals until the steam temperature at the valve chest is at least 350ºC o
•
Once the turbine has been confirmed working properly engage the Auto-Spin facility o
•
The shaft must not be allowed to remain stopped for longer than three minutes.
Note: the amount of steam admitted by the auto-spin system is insufficient to properly warm through the turbine.
At STANDBY, change to WHEEL HOUSE control
Every three months the turbine is to be turned ahead and astern using the emergency control fitted on the main throttle valve.
Manoeuvring The turbine will normally be operated on lever control when the speed is automatically controlled in response to the position of the selected telegraph (wheel house or engine control room) In the event of a fault developing with the control system it is possible to operate the turbine from the Engine Control room using the engine telegraph in addition to this there are other fitted units that can be used for Emergency use. If control oil pressure is not available the manoeuvring and nozzle valves can be operated by their manual hand jacks. •

avoided, particularly at higher power. After astern operation, restoring full ahead power will take much longer than acceleration from normal condition. For details consult the instruction manual for Astern Operation Limitations.
Action to be taken in case of Turbine Vibration Abnormal turbine vibration when starting or increasing speed is most likely to be due to thermal distortion of the rotors and should be dealt with as follows: •
Reduce speed immediately to DEAD SLOW or STOP
•
Using the remote control in the Engine Control room increase the speed very slowly, turn alternatively ahead and astern at 10 – 20 RPM for about 15 minutes observing the vibration monitor
•
When vibration has reduced to normal, increase speed again checking the vibration monitor. If no abnormal vibration is observed power may be gradually increased to full.
•
If vibration persists the turbine should be shut down and a through investigation carried out.
Open Sea Operation When the control telegraph is in the FULL AHEAD sector, control mode changes from MANOEUVRING to NORMAL. The automatic drain valves, astern guard valve will close. The crossover and LP bleed steam valves will open manually / automatically. When pressure in the turbine is sufficient the HP should open manually / automatically. Note: The main feed pumps re-circulating valves are controlled only by the boiler load and are not dependant on the main engine control mode. (On NGSCO ships Turbine Control) The position of the ahead nozzle valves are controlled by a pre-set time schedule (see instruction book) In case of extreme emergency the time schedule can be bypassed by operating the installed bridge mechanism for this purpose and the speed is then controlled directly by the position of the telegraph. •
This facility must be used with extreme caution
Provided the ships speed is above 10 knots (see instruction book) the main condenser scoop valve will open and the sea water circulation pump will stop approx. 10 min after change over to NORMAL mode. (On NGSCO ships controlled by speed, RPM & throttle setting) The turbine should be carefully monitored whilst running up speed, paying particular attention to vibration and bearing oil flow and temperature. When the telegraph is reduced into the FULL Ahead zone the automatic/manual drain valves, astern guard valve and main condenser re-circulating valve will / should open, and the condenser cooling will change over to the pump. The crossover and LP bleed steam valves will close. The HP bleed valve will close after a time. Normal Operation The main engine is to be operated within the limits of power, maximum evaporative capacity and pressure of the boilers, and the revolutions per min set out in the commissioning letter issued when the vessel entered company service.

Only if subsequent specific instructions have been issued by the Company, are the original commissioning letter parameters to be countermanded. Stand By Manoeuvring The officer of the watch on the Bridge must give the Engine Department at least one hours notice before Stand By for manoeuvring. Regardless of the time of day or type of vessel, i.e. unmanned engine room or conventional watchkeeping, the Chief Engineer Officer, and the Engineer Officer of the watch or Duty Engineer Officer are to be informed. Reduction in speed from full speed to the recognised manoeuvring speed is to be as gradual as possible and in accordance with the manufacturer’s instructions. The operating parameters are to be maintained avoiding sudden variations of the boiler load etc. Control System Maintenance Testing and any maintenance of any turbine control system alongside a berth is strictly forbidden under live steam conditions. The main steam stop, guardian and bulkhead stop valves are to be shut prior to maintenance work being carried out. In the case where a simulated test would be unsatisfactory and operation with live steam has to be carried out, then the vessel is to be suitably anchored or stopped at sea, before maintenance or testing is carried out. Gearing Inspection During gearing inspection the following points are to be carefully examined. •
The lubricating oil jet nozzle brackets. locking plates, housing and pipe brackets for tightness
•
The lubricating oil pipe work system and nozzles for leakage
•
Nozzle alignment to ensure that the oil jets impinge accurately in the mesh between the wheels and pinion
•
The gear teeth contact areas for evidence of pitting, tearing etc. All indications of deterioration are to be recorded
The areas in question are to be coated with blue marking and photographs or “sellotape” impressions taken.
Securing the Turbine in Port Do not stop the turbine rotors for a time period longer than three (3) minutes, when the gland seal steam supply is on the rotors, to prevent thermal deflection. Ensure that the lubricating oil pump and system is always operating when the turbine rotors are being turned. •
After FINISHED WITH ENGINES, select ENGINE ROOM control and ensure that both the ahead nozzle valves and astern manoeuvring valve are fully closed, then select the control mode to OFF

After ensuring that the propeller shaft is stationery, engage and start the turning gear. (On NGSCO ships switch on the 10 RPM trip switch)
•
When the pressure in the main steam line has fallen to zero “crack” open the intermediate stop valve by pass valves to maintain a pressure of about 5 bar in the main steam line. This will ensure that the line and manoeuvring chest remain hot
•
The control oil pumps can be stopped if required
Securing the Turbine for Long Period Before the main condenser can be shut down the turbo-generator exhaust, closed exhaust dump steam must be closed down. •
Stop the main condenser vacuum pumps and allow the vacuum to decay slowly.
•
When the condenser pressure has fallen to atmospheric, shut off the gland steam supply. o
15.2
Under no circumstances should gland steam be shut off whilst the condenser is under vacuum. To do so would result in cold air being drawn in over the turbine glands which could cause rotor distortion.
•
Ensure that the make up feed is directed to the atmospheric drain tank, then stop the main condensate pumps and close the recirculation valve. At least 30 minutes should have elapsed from closing the intermediate steam stop valves.
•
When the LP turbine exhaust has cooled sufficiently the main circulating pump can be stopped. Allow at least two hours after closing the intermediate steam stop valves.
•
After a minimum of 6 hours the turning gear can be stopped and the lubricating oil and control oil systems secured.
•
Start the dehumidifier to prevent condensation in the gearbox contaminating the oil.
•
If turbine is to remain shut down for an extended period, drain the main condenser and dry the hot well. Run the lubrication oil pump for a short while and turn the rotors approximately 90 degrees every week.
TURBO GENERATORS
Note: On ships with fitted turning gear motors the turbine trips cannot be reset unless the turning gear is disengaged. On ships with portable turning gear motors extreme caution must be taken so as not to start the turbine with turning gear engaged. Governor oil pressure is led via an orifice to a trip cylinder attached to the main stop valve. When oil pressure is applied to the cylinder its piston rises and operates a latch against which the stop valve spindle nut(spring holder) resets, enabling the valve to open. When oil pressure is released from the trip cylinder the stop valve closes under the action of its spring, stopping the turbine (see instruction books for variation to the system, for your ship)

Preparation and Starting For more detailed description of the operating procedures, please refer to the Instruction Manual of Turbo Generators. •
Check the oil level in the sump. Note that the level will drop when the oil pump is started
•
Drain off any water in the sump. If a significant quantity is present consideration should be given to purifying or changing the oil. The source of any contamination should be traced and rectified
•
Ensure that the power supplies to the auxiliary oil pump starter, turning gear starter and local supervisory panel are on
•
If the control cooling water system is up to temperature, open the cooling water valves to the turbine oil cooler and alternator air coolers (if fitted)
•
Start the auxiliary oil pump
•
When satisfied that the oil is circulating, engage and start the turning gear
•
After the turbine has been turning for a minimum of 10 minutes, warm through the gland steam supply line and gradually bring the receiver up to normal pressure. Ensure that the automatic control is operating Caution
The gland steam spill line joins the exhaust upstream of the exhaust valve. Take care not to all the exhaust to become pressurised. •
After ensuring that the gland sealing system is operating correctly, cautiously open the by pass valve of the exhaust valve to the condenser in use. When the turbine exhaust pressure gauge indicates the same vacuum as the condenser, open the exhaust valve fully and close the by pass
•
Ensure that the main stop valve, intermediate steam stop valves and exhaust valve are closed, and the steam line vent and all drain valves are open.
•
Open the upper intermediate steam stop valve and carefully crack open the bypass around the lower intermediate stop valve. As the line warms up the drain valves can be throttled but they should not be completely closed until the turbine is running
•
After a further 10 minutes (longer if possible), stop and disengage the turning gear, ensuring that the clutch lever is locked in the disengaged position
•

MONOWALL MARINE BOILER
The monowall marine boiler is preferred when firing with gas and fuel. Monowall boiler construction is a method of fabrication wherein the boiler tubes forming the outer periphery of the boiler are joined together to form a gas tight water cooled envelop. The tubes welded together by mean of “fins” perform the structural function previously done by the boiler framework and casing. The use of a monowall construction eliminates the need for refractory linings except where transition occurs between finned and non finned tubes, that is where the tube spread to enter the drums and to form burner sootblower openings, etc. In these areas a skin case, lined with refractory materials, is constructed. For oil fired only marine boilers, monowall construction usually eliminates the heavy air casing but for oil and Methane gas fired marine boilers, pressurised air casing are fitted to eliminate the possibility of gas leaking into the machinery spaces. The boiler has been designed to suit advanced steaming conditions with the final steam temperature controlled by attemperation between the superheater primary and secondary passes. The furnace is large to give a conservative firing rate and proportioned so that the burners can be arranged with ample flame clearance and flame length. The burners are positioned in the furnace roof to meet the latter requirements and the furnace and superheater spaces are completely water cooled. External down comers from the steam drum to the water drum and the lower water wall headers ensure an adequate circulation of water under all steaming conditions. The economiser is supported on the boiler structure. The boiler superheater and economiser are double cased, the space between being pressurised with air from forced draft fans (separate pipe) to prevent gas leaking into the machinery spaces. All the combustion air enters directly to boiler windbox. The air casing are insulating externally with low temperature insulating materials protected with light plating. The monowall tube areas within the air casing are left bare, insulation is not fitted or required. It is essential in a gas fired boiler that highest parts of the furnace are continuously vented to prevent any dangerous accumulations of gas under the furnace roof. A number of special vent passages are CONTROLLED

provided in the gas seal between the furnace roof tubes and super heater screen wall tubes for this purpose. The boilers are fitted with sliding feet which are fitted with grease nipples and it is important to ensure that they are kept well greased. Failure to grease the feet may result in distortion of the boiler and tube leaks due to expansion and contraction when firing up or taking the boiler out of service.
Superheated Steam Temperature Control The final superheated steam temperature is controlled by attemperation (desuperheating) of the steam between the primary and secondary steam passes of the superheater A proportion of the steam flow from the primary pass is diverted through the superheater, which is located in the steam drum and the excess heat is transferred to the water in the drum. The desuperheater steam is mixed, before entering into the secondary pass, with the remainder of the steam passing through the desuperheater or by-passing this is controlled by two inner linked control valves one on each steam line. The total steam flow passes through the secondary pass under all steam conditions.
Sootblowers Steam operated sootblowers are fitted to maintain all heating surfaces in good condition for long periods. Boilers are to be sootblown every day or depending on actual condition of boiler when firing on fuel oil. When firing on gas only soot blowing can be reduced to every third day. Boilers to be soot blown before entering port, regardless if fired on fuel or gas. The dual fuel burner registers are fitted with pneumatically operated air sleeves and igniters. The atomising steam, fuel gas valves are also fitted with pneumatic actuators. Steam is the normal atomising medium when burning heavy fuel oil: air is used for starting up and when burning distilled fuel. Oil burners that are not firing are cooled by maintaining the atomising steam supply. The burner oil passages are automatically purged with steam from the atomising supply whenever they are extinguished. When firing on gas only hot fuel is circulated through the boiler oil headers so that the oil burners can be ignited instantly when changing to dual fuel or oil only firing. The firing will automatically change from gas only to duel fuel should the cargo tank pressure fall below a pre-set limit (fuel oil back up) or to fuel oil only (fuel oil boost up) if the master gas valve closes. There is no automatic boost up when an individual boiler gas valve trips. It is important that all oil burners are fitted in place and ready to be lit when burning gas only. All manual fuel oil and atomising steam valves on the burners and in the supply lines must be open. The burners are each fitted with 6 gas spouts. Three of these have multi-hole nozzles where gas must mix with the air outside the nozzle before it ignites (external mix). The three other spouts are arranged with an internal gas nozzle about 400 mm from the end of the spout. This nozzle acts as an ejector and sucks air into the spout through openings adjacent to the nozzle. The air and gas will

therefore pre mixed (internal mix) in the spout before it leaves through the single opening in the nozzle at the end. The gas spouts have alternating internal and external mix spouts equally spaced round the periphery of the impeller. This arrangement ensures even distribution of air to the oil and gas flames, stable flames and good ignition of the gas flame over the whole load range.
Burner Operation Gas-Firing Ensure that the cargo system is lined up for gas burning. The low duty heater should be in service and on automatic control. The line from the vapour header through the LD heater must be open down to the gas master valve. When gas is admitted to the first boiler, this should be done with the gas in free flow before the compressor is started. When operating in dual fuel mode the total air requirement for combustion is based on the total fuel (oil + gas) flow to the boiler. The air flow to the boiler will be the same to each burner. Therefore the fuel flow must also be equal to each burner. This means that when burning dual fuel on a boiler it must be dual fuel on all burners at the same time. Never fire with dual fuel on one or two burners and gas or oil only on other burners on same boiler.
Steam Dump Control The steam dump system has two control functions. One for controlling the superheater outlet pressure if the boiler load is below the boiler turn down range or if the boiler load under transient conditions changes faster than the combustion control can respond. The other function is to dump steam to allow the boiler to burn excess boil off gas when the cargo tank pressure is high.
15.4
FEED WATER PUMPS
Preparation for Start-Up Ensure that the superheated steam and closed exhaust systems are prepared for duty. Piping must be well drained before supplying steam to the turbines. The standby pump steam traps (a), steam supply line (b), high pressure steam chest (c) and turbine exhaust end, must be periodically checked to ensure a trouble free start in all conditions. The pump is fitted with mechanical/shaft backing seals, and a void space between the pump and worm gear housing helps prevent the ingress of any gland leakage water into the oil system. Check the oil sump regularly for any ingress of water. Ensure that seal cooling water lines to both ends of the pump are pressurised (pumps with mechanical seals) which enables a flow into the seals. Insufficient seal cooling water flow from the condensate system may result in mechanical seal failure. Therefore it is important to adjust the flow correctly in accordance with the instruction manual.

On no account must steam atomising be used with Diesel or low viscosity fuel oils
•
Once the appropriate steam heating system pressure is reached the boiler is to be operated on heavy fuel oil
Purging If the boiler furnace or furnaces are fitted with automatic purging systems then these must be fully operational. If the furnace or furnaces are not fitted with automatic purging sequence systems, or they are not operational, then prior to burner ignition, and on each subsequent occasion prior to reigniting the burner or burners, the furnace spaces are to be purged using the forced draught fans to give a minimum of five full changes of furnace air. Should the burner fail to ignite, or flame failure occur for any reason then it is essential that the furnace is visually examined for unburned fuel and purged as above mentioned before any attempt is made to re-ignite the burner. Manual Firing If manual firing has to be resorted to, then the procedure must be in accordance with the manufacturer’s instructions and as agreed with the Technical Department of the relevant management office.
Firing Manufacturers recommendations are to be followed, however, by way of a general recommendation to prevent damage to the boiler, gradual and uniform heating is essential. One burner should be used initially using the smallest tip available. Steam should be raised over a six hour period. In cases where extensive repairs have been made to the refractory, or parts of the boiler subject to pressure, then steam should be raised over a 24 hour period. During this period firing is to be using alternate registers.
Flow through Superheaters It is essential that steam flow is maintained through superheaters at all times except in certain cases of emergency. In the case of an emergency when steam is required at short notice the boiler manufacturers instructions are to be adhered to.
Venting From the commencement of firing, and until steam is being generated provision must be made for venting all air from the boiler. This should be done by means of the designated air release cock or if this is not fitted by means of the steam pressure gauge cock. Under no circumstances are the steam connections of the water level gauge glasses to be used for venting purposes.
Use of Boiler Gauge Glasses Any defect must be reported and rectified as soon as is possible.

Low pressure water level gauge glasses are to be "blown down" by an approved method for the type of gauge glass at least once per week or whenever the water level indication is suspect. High pressure water level gauge glasses are to be blown through only when necessary. The water level is to be kept within the upper and lower limits at all times when the boiler is in use. If the water level disappears from either the top or the bottom of the gauge glass and does not return immediately, then all burners are to be shut off and kept shut until the water level is restored in the gauge glass. Any loss of water level from the gauge glass above or below the set limits must be recorded in the Engine Room Log Book and reported to the Chief Engineer. When the water level indicated is suspect it is absolutely essential that remote water level indications are not used in place of the readings from the water level gauge glass.
Testing of Boiler Water Controls, Regulators, Alarms and Trips All boiler controls, regulators, alarms and trips must be tested regularly in accordance with the applicable P.M.P. In preparation to test the boiler, removal of the easing gear and lifting of all gags must be done before hand and any adjustments to the gags and the valves should be done with the boiler in an unfired state. Each test is to be recorded in the Engine Room Log Book, with the signature of the Engineer Officer who conducted the test. Boiler level alarms or trip defects are to be rectified immediately. The boiler must not be operated except in exceptional circumstances with any such safeguards inoperative. Should it be necessary to operate the boiler in this condition the Chief Engineer must be advised and the boiler must be monitored 100% of the time. The appropriate Management office is to be advised of details of any defects, remedial measures taken, and confirmation of satisfactory re-tests which are also to be recorded in the Engine Room Log Book.
Boiler Water Tests and Treatment Water in the boilers, steam/steam generators together with samples of water from their respective feed water systems are to be tested daily. The testing is to be in accordance with procedures laid down by the suppliers of the water treatment systems. Test readings which indicate salt water contamination or loss of chemical reserve are to be investigated immediately. Completion of all tests are to be recorded in the Engine Room Log Book and the full results entered on the report forms issued by the water treatment suppliers. Departures from normal operating conditions or unusual conditions are to be recorded, and the relevant Management Office immediately advised.

These instructions may be found in the suppliers instructions manuals, data sheets or on the chemicals containers. Should no instructions be available on board, the appropriate Management office must be advised. The special protective clothing and equipment supplied to the vessel for the handling of chemicals must be maintained in good condition. This clothing is to be used as directed by the Company or in accordance with the Chemicals Suppliers instructions. Deficiencies or defects in protective clothing must be reported and replacement orders placed with the relevant Management Office at the earliest opportunity. Attention is drawn to the spontaneous combustion properties of certain oxygen scavenging materials such as hydrazine. Cleaning materials like rags, cotton waste, sawdust etc. which have been contaminated with chemicals of this type, must therefore be washed or destroyed immediately after use, to avoid the risk of self ignition.
Blowing Down Boilers To control the quantity of total dissolved solids contained in the boiler water, each boiler, subject to the type and application is to be blown down at least once per week. Blowing down is to be carried out irrespective of the salinity or chemical reserve readings. Ideally at least one tonne should be blown down from each boiler, with the actual quantity recorded in the Engine Room Log Book, and the boiler water report forms. Blowdown should be carried out ideally under light load conditions, with a constant watch placed on the boiler water level. Use is also to be made of the surface blow down valve to remove scum from the boiler.
Boiler Maintenance at Sea Should it become necessary in cases other than an Emergency to shut a boiler down for repairs or routine maintenance, and if this shutdown is liable to cause a reduction in speed or adversely affect operational requirements, the appropriate Management Office must be informed of. •

Safety Precautions During Boiler Maintenance and Cleaning During the cleaning and maintenance of boilers which involves personnel entering the gas or water spaces, the full safety precautions outlined in the Fleet Standing Instructions for entering enclosed spaces are to be adhered to. In particular, respirators, protective clothing, and low voltage lamps are to be used.
Smoke Emission Under various clean air regulations applicable to the area your vessel is in, it may be an offence to emit dark smoke. The following is a guide as a basic minimum requirement: •
Continuous emissions of dark smoke from forced draught oil fired boiler furnaces are only permitted for a maximum of 4 consecutive minutes, and that the total is not to exceed 10 minutes in any 2 hour period o
For a natural draught oil fired boiler the total period of emissions of dark smoke is not to exceed 10 minutes in any 1 hour period.
•
Emissions of dark smoke from all other sources are only permitted for a maximum total of 5 minutes in any 1 hour period.
•
In no case is the emission of black smoke permitted for more than a maximum total of 3 minutes in any 30 minute period.
Particular care must be taken with regard to the references and the difference between “dark” and “black” smoke. Impending legislation will impose strict regulations with regard to nitrogen (Nox) emissions, which will also vary according to the geographical area. It is therefore important that the Master requests information from the local agent if he is unsure about the applicable emission regulations, and pass this information to the Chief Engineer.
Handling of Idle and Standby Boilers The basic steps for all boiler lay-up procedures are: •
Pre-lay-up boiler waterside cleaning, if required
•
Boiler flushout, neutralisation, passivation and formation of protective magnetite film
•
Fireside preparation and lay-up
Introduction Boilers may have to be removed from service for varying periods of time and are either required to be kept in lay-up, standby or to be inspected. If necessary, they may have to be cleaned before being returned to service or laid up. Special attention must be given to standby or idle boilers in order to prevent corrosion. Adequate corrosion prevention measures during operation can be offset if the necessary corrosion prevention measures are not extended into the standby and idle periods. Further, corrosion can occur on the fireside of the boilers if proper corrosion prevention measures are not taken.

Standby Steam Generating Equipment If a steam generator is used as standby equipment and is maintained under pressure, it should receive the same chemical treatment as an operational boiler. If it is not to be maintained under positive pressure, certain additional precautions must be taken. These precautions are detailed in the section “Waterside Wet Lay-Up of Boilers”. Idle Steam Generating Equipment Three general methods are used in laying up the watersides of boilers: •
Wet method
•
Dry method with the unit open for free circulation of air
•
Dry method with the unit completely closed and dosed with a desiccant. The degree of corrosion protection using either of the dry lay-up methods depends on maintaining a completely moisture-free condition. As this is very difficult to maintain without special equipment or unusual attention, the wet lay-up protection is the preferred method
Need for Chemical Cleaning A number of new vessels may go from the builder’s yard into lay-up without commissioning either the boilers or other machinery. Proper lay-up techniques must be practised for idle equipment even if it has never been in operation. Before pre-operational lay-up, the economiser and the boiler should be cleaned with an alkaline detergent solution to remove preservatives, oil and grease. Units operating at relatively high drum pressure may also require chemical cleaning to remove mill scale and corrosion products. Superheaters require special treatment during such pre-operational cleaning, particular attention being paid to draining. To ensure successful deposit removal and to avoid potential equipment damage, qualified personnel are to supervise any necessary pre-operational cleaning. Operational boilers must be removed from service properly to minimise adherence of boiler water suspended solids on boiler metal surfaces. This can be accomplished by immediate flushing with hot, pressurised water, while waterside surfaces are still moist. If a boiler removed from service contains harmful deposits that formed during operation or manifested due to improper shutdown procedures, chemical cleaning may be required before lay-up is achieved. Scheduling of Chemical Cleaning Boilers are to be cleaned before lay-up is commenced. Well operated clean boilers may go directly into lay-up status without cleaning. Cleaning before lay-up has been a controversial subject because of the need for adequate passivation of metal surfaces after chemical cleaning. Passivation requires the formation of a protective metal oxide film on metal surfaces. The recommended procedure, therefore, is to operate all acid cleaned or new boilers with a solution of passivating chemicals after the chemical cleaning, rinsing and neutralisation steps to obtain metal passivation (magnetite film) before lay-up. Passivation is best carried out at 20kg/cm2) 300psi)using 200 ppm hydrazine in distilled water. A lower pressure may be used on boilers which have a lower maximum pressure rating. In the rare event that such cleaning is done it should be carried out by a shoreside company who will be better placed to correctly dispose of any waste resulting from chemical cleaning. The following procedure should be followed in order to provide protection against corrosion when boilers and exhaust gas economisers are removed from service.

Waterside wet Lay-Up of Boilers – Procedure This method entails completely filling the boiler to exclude any air, maintaining a high concentration of hydrazine in the water to scavenge any oxygen that may be present, and ensuring that the boiler water pH is kept at a satisfactory level. The calculated quantity of corrosion inhibitor can be added immediately on completion of service and before lay-up without emptying, if the boiler is known to have clean internal surfaces. Treatment and Filling of Steam Generating Equipment Water treatment conditions required to give the necessary corrosion protection during standby of layup periods are: Oxygen Control – 200ppm minimum – Hydrazine as N2H4 pH – 9.0 – 10.0 “p” Alkalinity – 80 – 120 ppm Preparation of Lay-Up Solution The highest quality water available should be used for laying up boilers. Demineralised water, steam condensate, softened water and boiler feedwater are generally acceptable for lay-up of auxiliary and waste heat boilers which do not have superheaters. Water containing significant amounts of suspended materials must not be used. It is especially important that only high quality condensate or demineralised water and volatile chemicals be used in preparing the lay-up solution for boilers with non-drainable superheaters and/or reheaters. To provide the necessary hydrazine level, the recommended dosage of corrosion inhibitor per ton of water needed to completely fill the unit must be dosed. Correct pH/alkalinity levels can be established by the addition of concentrated alkaline liquid to one ton of neutral water (untreated) to raise the “P” alkalinity to the 80-120 ppm range (pH 9-10 approximately). When only volatile chemicals are used to elevate the pH of the water, the necessary quantity of the condensate corrosion inhibitor must be added to raise the pH to 10 in high quality water. For boilers that are to be fired before lay-up status is achieved, a phosphate boiler water treatment is to be dosed to provide “in-service” levels of phosphate reserve to prevent any possible scale formation on the hot boiler tube surfaces during this pre-lay-up firing. Removing Boilers from Service Boilers that are to be put immediately on standby after service without draining and refilling should have normal in-service treatment levels established prior to shut down. After the fires have been shut off, the necessary amount of corrosion inhibitor to provide a recommended level of 200 ppm hydrazine should be dosed directly to the boiler. (The normal in-service alkalinity levels will give the necessary boiler water pH as indicated above). The boiler (excluding superheater) should then be completely filled with hot deareated feedwater, if available, or treated water (200 ppm hydrazine), to exclude all air, with particular attention paid to any parts where air may be trapped. All external valves or connections should be kept tightly closed or blanked off to prevent leakage of water or ingress of oxygen. A small tank should be connected to an available fitting on top of the boiler (e.g. vent line) to ensure the boiler is maintained completely full. The boiler should then be filled until water overflows into this tank. This will provide a suitable head of water. The level in this tank should be periodically inspected and be maintained throughout the shutdown period. This will also take care of small water volume variations due to temperature changes.

Boilers which are to be put on standby for any reason after inspection or cleaning should have the necessary quantities of phosphate water treatment, corrosion inhibitor and concentrated alkaline liquid dosed to the boiler during. The boiler should then be filled to working level and fired to provide sufficient circulation to obtain uniform concentrations of treatment throughout the boiler and to eliminate oxygen. Boilers which are to be laid up after inspection or cleaning with no application of heat only require the necessary quantities of corrosion inhibitor and concentrated alkaline liquid or a multifunctional boiler and feedwater treatment to be dosed to the boiler during filling. This is to be completed immediately after shut-down. When any steam generating unit is shut down, close attention should be paid to the boiler manufacturer’s procedural recommendations. Superheaters – Special Precautions Where boilers are equipped with superheaters, the instructions supplied by the boiler manufacturers for laying up of the superheaters are to be followed. Where no instructions are supplied, a satisfactory procedure is to completely fill the superheaters with either distilled or demineralised water treated with 200 ppm (minimum) hydrazine. It may also be necessary to add a small quantity of inhibitor to raise the pH to the 9.0 – 10.0 range. Only corrosion inhibitor is to be used in superheaters as these products will leave no deposits when the unit is returned to service. Double Pressure Boilers Particular attention should be paid to the filing of the primary system heat exchanger coils with inhibitor (200 ppm hydrazine) treated boiler water. The “header tank” must always be above the level of the tube nest. The recommended lay-up treatment levels will normally hold at well above any point where corrosion is likely to commence during the idle period. If additional treatment is necessary, the water in the boiler should be lowered to working level and the necessary treatment solution prepared before being added directly to the boiler. The boiler should then be refilled as described for the initial treatment of water. Feedwater Heaters The waterside of feedwater heaters should be treated the same as the boiler during lay-up periods. The shellside normally should be dried, pressurised and blanketed with nitrogen during lay-up. However, it can be flooded with condensate containing 200 ppm hydrazine expressed as n2h4 and corrosion inhibitor treatment needed to maintain the pH at or near 10.0. De-airators usually are nitrogen blanketed during shutdown. If nitrogen is not available, the deairator can be laid up with hydrazine and inhibitor treated water as discussed for feedwater heaters.
Dry Lay-Up General The objective of dry lay-up is to keep metal surfaces free of moisture. Oxygen from the surrounding atmosphere dissolved in the liquid could make it very corrosive. The waterside of auxiliary and waste heat boilers can be laid up dry. A boiler containing porous moisture-retaining deposits (scale) should not be laid up dry due to potential occurrence of underdeposit corrosion. The recommended dry lay-up methods for auxiliary and waste heat boilers are given below: •

Handling of the Fireside of Steam Generating Equipment When boilers are to be laid up, the fireside must be considered as well as the waterside. The two common methods used for fireside lay-up are identified as “cold” and “hot”. The preferred method for each installation will depend on local conditions. The primary objective in fireside lay-up is to keep the metal surfaces dry. If appreciable amounts of deposits are present, the fireside should be cleaned before lay-up. This is especially true where oil (or coal) containing high concentrations of sulphur has been used as the fuel. The deposits that develop when these fuels are burned can absorb moisture and form corrosive acids. In come instances, it may be desirable to spray the metal surfaces with a dilute solution of an alkaline chemical such as concentrated alkaline liquid after the clean-up to control corrosion. The fireside of laid-up boilers should be cleaned mechanically or washed with boiler water or a 0.1% -0.5% solution of concentrated alkaline liquid to neutralise, as far as practical, acidic constituents, and to remove by draining. A heater should then be placed in the furnace to thoroughly dry it. It is good practice to keep a small heater in the fireside to keep it dry during the lay-up period. Cold Lay-Up The following items should be considered where a cold lay-up is planned: Keep the metal surfaces dry by the use of dehumidification with desiccants along with air circulation, of dry warm air, or a combination of both. The relative humidity of the air should be kept as low as practicable. Seal the furnace as completely as possible to minimise entry of moist air. •
Make provisions to keep rain water from entering the boiler by capping the funnel. Log this fact for future reference for uncapping when the unit is to be returned to service
•
Inspect the fireside once per month for evidence of active corrosion and, if found, take corrective measures as previously discussed
Hot Lay-Up The following items are to be considered where hot lay-up is planned: •
Since certain boilers cannot be effectively cleaned on the gas side without extensive dismantling, a hot lay-up may be appropriate
•
The hot lay-up method may not be practical for a lay-up period longer than six months because of energy costs
•
To prevent moisture absorption by deposits on the fire and gas side, the temperature of the metal surfaces must be kept at 77 degrees centigrade (170 degrees Fahrenheit) or higher
•
Fireside metal temperatures can be maintained at a safe level by controlled very light-firing with low sulphur fuel or by the use of electric or other type hot air blowers. Care should be exercised never to dry-fire a boiler
Safety The following safety factors should be observed in handling chemicals: CONTROLLED
Revision: 01 Apr 2012 Approved by DPA/DMR Page 19 of 25
THOME SHIP MANAGEMENT PTE LTD
OME Document No. 015 LNG Technical Operations
•
Always read Material Safety Data Sheets for the chemicals to be used
•
Make sure to use the recommended handling procedures and precautions
•
Follow all governmental regulations and other appropriate safety methods in handling chemicals
•
Wear safety equipment such as goggles, rubber gloves, aprons and boots when handling lay-up chemicals
•
Bodily contact with lay-up chemicals, especially strong alkaline solutions and volatile chemical, should be avoided
•
Remove clothing immediately if contaminated with lay up chemicals. Discard them or launder before reuse
•
Wash skin which has been in contact with chemicals using large quantities of flowing water
•
If eyes are splashed by lay-up chemicals, immediately flood with gently flowing water for at least 15 minutes and then have eyes checked by a physician
•
Do not enter equipment laid up with nitrogen blanketing until the nitrogen is purged and tests show that sufficient oxygen is present to sustain life
•
When entry into a furnace is required, hard hats must be worn. The potential for injuries caused by slag, debris, tools etc., falling on personnel must be eliminated
Start-Up after Lay-Up Wet Lay-Up After lay-up, a boiler must be drained and inspected. This is especially important if the boiler was laid up without first conducting an inspection and cleaning the internals. If a boiler has to be returned to service urgently, for one reason or another, uncap the funnel, and lower the water level within the boiler to the correct level. Heating should be commenced by introducing into the furnace the smallest burner, for warm-through. Drum vents and superheater vents and drains must be open to dissipate the high levels of volatile chemicals. These products will volatilise harmlessly in the atmosphere, and the boiler can be put on line when the working pressure is achieved. When the system has been returned to service in the normal manner, boiler and feedwater tests are to be conducted and recommended working treatment levels re-established. During this start-up period, condensate salinity alarms may be activated temporarily due to high levels of hydrazine and ammonia circulating. Testing Lay-up solutions should be tested at 3 to 6 month intervals. If the tests show that chemical concentrations have decreased below the recommended minimum, a practical procedure may be to add additional lay-up solution, re-circulate by lowering the water level and operating at low load, and then follow the procedures previously described. The favoured procedure for testing the water of laid-up boilers is to take a representative sample (via sight glass or other convenient point) in a high purity sample bottle and dispatch it for analysis. A special test for very high concentrations of hydrazine (up to 350 ppm) can be provided if qualified laboratory personnel and equipment are available at the lay-up location. This test procedure does not lend itself for use by untrained personnel, and it is preferable to send samples to the manufacturers of the chemical treatment system for periodic testing as indicated above. This special

test is not normally necessary as long as the initial dose of hydrazine is adequate, and there are not abnormal conditions of water loss and high makeup. Dry Lay-Up If the boiler or auxiliaries have been pressurised with nitrogen, vent and thoroughly purge the equipment of nitrogen with dry air. This is mandatory if personnel intend to enter the equipment since nitrogen will not sustain life. Remove all trays of desiccant from all locations and clear away all traces which may have been spilled. Handle the equipment in the normal manner when returning it to service.
Boiler Lay-Up Summary Sheet •
Remove boiler from service
•
If boiler is dirty, clean the internals with a suitable descaling compound
•
Refill boiler with acceptable water after neutralising and passivating internal surfaces using corrosion inhibitor and concentrated alkaline liquid or multifunctional boiler and feedwater treatment to scavenge the oxygen and elevate the pH of the water, respectively. For passivating, inhibitor should be dosed to give a hydrazine reserve of 200 ppm (1.3 litres of corrosion inhibitor/ton distilled water). Concentrated alkaline liquid should be added to give a “P” alkalinity reserve of between 80 and 120 ppm. The addition of 0.13 litres of concentrated alkaline liquid to one tonne of neutral distilled water will elevate the “P” alkalinity to the 80-120 range
•
Fire the boiler at low pressure (20 kg/cm2 – 300 psi maximum or a lower level based on the units normal operating pressure) for 24 hours to achieve magnetite film formation and thus complete passivation of internal surfaces. Shut down boiler, drain and inspect internal surfaces to verify magnetite film formation is established
•
If the boiler is clean or after establishing magnetite film formation, add sufficient hydrazine to elevate the reserve in the boiler water to 200 ppm. Elevate to pH to the 9-10 range by addition of condensate corrosion inhibitor or concentrated alkaline liquid, if required
•
Fill the boiler until the header tank connected to the steam drum vent pipe (highest point of boiler) is ¾ full
•
Superheaters should be filled with demineralised water treated with 200 ppm hydrazine, and condensate corrosion inhibitor only (elevate pH to about 10)
•
Protect the boiler gas (fire) side by maintaining all surfaces in a dry condition. This can be effectively achieved by capping the funnel and placing a small heater in the furnace. Fireside acid deposits can be effectively neutralised by washing the surfaces with 0.1%-0.5% solution of concentrated alkaline liquid before lay-up procedure is commenced
•
Before re-commissioning the boiler, uncap the funnel and inspect internals for corrosion. Clean boiler internal as necessary

ENGINE ROOM OPERATIONS
Operation of Unmanned Machinery Spaces On any ship certified for unmanned operation the maximum usage of the facility should be made while at sea. On any ship certified for unmanned operation the machinery spaces are to manned for a minimum of 8 hours in any 24 hour period. Vessels must not operate with the machinery spaces unmanned in the following circumstances: •
During preparation for departure
•
During manoeuvring or standby situations
•
At sea or at Anchor when the Master or the chief Engineer requires the engine room to be manned due to adverse weather, traffic etc.
•
When the cargo handling plant place a high and variable load on the electrical or steam generating plant
•
When port regulations prohibit unmanned engine rooms
•
With any fire, major alarm, or safety system inoperative
•
With any major control or communication system inoperative
•
If the Bridge console is inoperative
•
Before the Chief Engineers specific instructions for operating in the unmanned condition have been compiled
The term Duty Engineer officer refers to the senior engineer officer appointed by the chief Engineer as his representative for the appropriate period of operation. The Duty Engineer has the full authority for the safe and economical operation of the propulsion and auxiliary machinery plant. Under normal “full away” sea passage conditions the Chief Engineer is to designate the unmanned period of operation which is to be posted on the Bridge and in the Engine Room Control Room. The Chief Engineers instructions will vary according to the ship, and machinery type but will typically be as follows:
Prior to Engine Room Unmanned Condition Ensure that all daily service tanks for fuel, lubricating oil, cooling water etc. are full. An inspection of all active and operational machinery and systems in all the machinery spaces, particularly for fuel and lubricating oil leakage, is to be carried out. •
Check that all bilges and seawells are empty
•
Check that all flammable liquids are in sealed canisters
•
Check that all oil spills etc have been cleaned up
•
Check that all waste, rags and other cleaning materials have been stowed away
•
Check that all engine room gear, spare parts etc. are properly secured
•
Check that all alarms are active

OME Document No. 015 LNG Technical Operations
During the Engine Room Unmanned Condition The Duty Engineer Officer must notify the bridge when he is about to enter the machinery spaces. He must not enter the machinery spaces alone, unless his safety is confirmed to the bridge at twenty minute intervals. If confirmation to the bridge, by telephone or deadman alarm, is not received within the twenty minute period then the Bridge watchkeeping officer must first attempt to contact the Duty Engineer, if unsuccessful then another engineer officer or officers must be called to attend. When the Duty Engineer leaves the machinery spaces then the Bridge watchkeeping officer must be notified. In the case of an alarm the Duty Engineer must verify the cause of the alarm and take any necessary measures to correct the alarm condition. If necessary he is to seek advice or help from his fellow engineer officers. In the case of fire, flooding, serious machinery or electrical malfunction or other serious threat to safety the Duty Engineer must notify the Bridge and the Chief Engineer. Two full log entries of the engine room machinery parameters are to be made during the eight hour manned period and one full log entry during the unmanned period. The Chief Engineer is to issue standing orders specific to the vessel detailing the operation of the machinery during the unmanned period. Means are to be adopted to ensure that entry into unmanned machinery spaces outside normal working hours is restricted to the Duty Engineer and any other persons as authorised by the Chief Engineer. Any authorised persons must follow the same procedure as the duty engineer for notifying the bridge watchkeeping officer. Access doors are to carry appropriately worded “Entry Prohibited” signs indicating the times during which the special restrictions are applicable.
15.7
CHIEF ENGINEER’S STANDING ORDERS
Whenever the Master or Deck Officer on watch requires a stand-by condition: Change to dual fire (if gas only), start aux. diesel generator/engage and immediately call the Chief Engineer. At any time the engineer on watch requires assistance or is in doubt concerning the condition or operation of the machinery, the Chief Engineer is to be called immediately. Despite the requirements to notify the Chief Engineer immediately in the foregoing circumstances, the engineer on watch should not hesitate to take immediate action for the safety of personnel, vessel, environment, or the machinery and equipment where circumstances require. The Chief Engineer shall be called when engine damage or operational interference occurs, which affects the safe operation of the ship and/or requires slow-down or stop of any machinery or systems, or whenever the Master or deck officer on watch calls for a stand-by condition.
