These are the question that I remember at present. I will update if I remember anymore questions. Cleared function 3 and function 5. Mr Banerjee was really good. He was very patient and if you were really close to the word he was looking for, he would accept the answer. Oxy-fuel Gouging

Oxy-fuel or flame gouging offers fabricators a quick and efficient method of removing metal. It can be at least four times quicker than cold chipping operations. The process is particularly attractive because of its low noise, ease of handling, and ability to be used in all positions. Process description Flame gouging is a variant of conventional oxyfuel gas welding. Oxygen and a fuel gas are used to produce a high temperature flame for melting the steel. When gouging, the steel is locally heated to a temperature above the 'ignition' temperature (typically 900deg.C) and a jet of oxygen is used to melt the metal - a chemical reaction between pure oxygen and hot metal. This jet is also used to blow away molten metal and slag. It should be noted that compared with oxyfuel cutting, slag is not blown through the material, but remains on the top surface of the workpiece. The gouging nozzle is designed to supply a relatively large volume of oxygen through the gouging jet. This can be as much as 300 litre/min through a 6mm orifice nozzle. In oxyacetylene gouging, equal quantities of oxygen and acetylene are used to set a near-neutral preheating flame. The oxygen jet flow rate determines the depth and width of the gouge. Typical operating parameters (gas pressures and flow rates) for achieving a range of gouge sizes (depth and width) can be seen in the Table.

When the preheating flame and oxygen jet are correctly set, the gouge has a uniform profile and its surfaces are smooth with a dull blue colour.

The black spots typically appear in the mid-stroke area of the liner, roughly between the oil quills and the scavenge ports. Analysis shows the deposits mainly consist of Calcium Sulphate, some water is found, and some oxidation products from hydrocarbons. Calcium Sulphate is commonly known as Gypsum. Calcium Sulphate is formed due to neutralisation of condensed Sulphuric Acid by Calcium Carbonate from the detergent additive of the cylinder oil. Neutralization of condensed Sulphuric Acid is necessary to prevent corrosion. Under normal conditions the Calcium Sulphate is carried away by the continuous refreshment of the oil film on the cylinder liner. If for some reason the refreshment rate of the oil film is reduced in certain areas of the liner surface, Calcium Sulphate is allowed to deposit, resulting in spots. Due to soot and other combustion related products adhering to the surface the spots appear dark or black. A possible reason for reduced oil refreshment in localised areas is the presence of areas where corrosion has previously taken place. These areas are slightly rougher and slightly recessed compared to the surrounding surface. Such areas are likely to retain the oil film and are slightly less exposed to the scraping effect of the piston rings. Influencing factors are liner wall temperature, fuel sulphur content, scavenge air humidity, oil feed rate, etc. Ideally, preventing Sulphuric Acid condensation on the Liner wall by staying above the acid Dew Point would prevent corrosion and the formation of black spots. However, Dew Point temperature is a complicated parameter related to quantity and concentration of the acid produced and the pressure in the cylinder. The recommended cylinder cooling water temperatures should therefore be closely observed. Water carry-over from the scavenging air cooler into the cylinder must be avoided. Free and unrestricted draining of condensate from the cooler and the water separator must be assured and the scavenging air temperature should be at the recommended level. The black spots described in this article are a regularly occurring phenomenon. Experience has shown that the black spots appear and disappear during engine opration, depending on different operational parameters. In general the black spots do not have a negative effect on the piston running conditions. Field inspections revealed normal piston ring condition and liner wear rates despite presence of the black spots as described in this article. Wärtsilä Switzerland Ltd. Winterthur, 27 January 2006

  -   Residual magnetism in the generator exciter field allows the generator to build up voltage during start-up. This magnetism is sometimes lost due to shelf time or improper operation, among other reasons. Restoring this residual magnetism is possible and is sometimes referred to as "flashing the exciter field". To restore the small amount of residual magnetism necessary to begin voltage buildup, connect a 12 volt battery to the exciter field while the generator is at rest, as follows: Remove exciter field leads F+ and F- from the voltage regulator. CAUTION: Failure to remove the field leads from the regulator during flashing procedures may destroy the regulator. Measure the exciter field resistance from the F+ to the F- lead. You should be able to read some resistance as you are measuring a continuous winding. An infinite resistance reading would indicate an open in the exciter field. Also check to be sure there is no path to ground. Connect F+ to the positive pole of the battery. Hold the F- lead by the insulated portion of the lead wire, touch F- to the negative pole of the battery for about 5 to 10 seconds, then remove. Reconnect F+ and F- to the regulator. Repeat the procedure if the generator fails to build voltage.  .'"'c FUNC 3 *TYPES OF DECK SEALS?

1 the purpose of both r the same ...to separate water from the steam..its just tht cyclone separators r used on larger capacity boilers.The mixture steam-water is forced to move around the cyclone and make the rotation. The more turbulent moving force the better separation..In low rated installations this drying may be achieved by fitting simple perforated plates immediately above the normal working level of the water in the steam drum in conjunction with a steam collecting pipe which is usually slotted to provide further separation... ƥ The feedwater pipe receives feedwater from the economizer and distributes it throughout the length of the steam drum. ƥ The chemical feed pipe is used to inject chemicals into the boiler to maintain the proper pH and phosphate balance in the boiler water. ƥ The surface blow pipe is used to remove suspended solid matter that floats ontop of the water and to lower the steam drum water level, when necessary. The surface blow pipe is also used to blow water out to lower the chemical level in the boiler when it becomes too high. ƥ The dry pipe is used to direct the steam to the steam drum outlet nozzle after it leaves the scrubbers. ƥ The vortex eliminators are used to reduce the swirling motion of the water as it enters the downcomers. ƥ The baffle plates are used to direct the steam to the steam separators.

ƥ The cyclone steam separators remove moisture from the steam. This is accomplished by the steam spinning or changing direction. The water drains back into the steam drum while the steam continues upward through a screen and scrubber that removes still more moisture. ? 1"2*"3"   " 3  c

MAN Variable Turbine Area (VTA) VTA system consists of a nozzle ring equipped with adjustable vanes which optionally replace the fxed-vane nozzle rings in MAN Diesel & Turboƞs standard TCA and TCR turbochargers. By altering the pitch of the adjustable vanes, the pressure of the exhaust gases on the turbine is regulated and thus the volume of charge air can be precisely matched to the quantity of injected fuel at all points in an engineƞs load and speed range. The result is reduced specifc fuel consumption, reduced emissions HC and CO2 and improved engine response. Benefts of VTA Up to 5g/kWh lower fuel consumption Lower soot and smoke emission Lower CO2 emissions Lower particle emissions Suitable for TCA and TCR turbochar >08/ /1     8

   2nd attempt his first que - r u related to Mr Ashish wankhede ??? i said no...:) He gave me a paper 2 write all the prvious que askd by last surveyor ( when i told him Mr. Trassi, he laughed out loud) I started with safety but he intrruptd and said wht he askd in func 6, any overhauling for main engine?? I told him RTA fuel p/p timing .....the he asked can u explain RTA main bearing removal. Told him the full procedure as posted in our MEO cl 2 group. he started drilling me in jack bolt.....how to open??...what happens if u open them, how it rotates??....from where u remove the jack bolt top or bottm??.... I was just imagining what will happen coz never seen in real and not read manual...:) then he drilled me @ how will u slide the bottom bearing shell out??.... Then he asked Bukl carrier cargo hold hatch is not opening in port. What will u do as second engineer??? unsatisfactory que for me and unsatisfactory ans for him. :) fucked up func 6 Func 3 All Marpol and Solas Ammendmnts? took 20-30 mins for this ans......he was listning and i was telling all i knew. said ok. told him about every thing in pushpak notes and Kapoor sirs xerox on amendments. IG blower regulations? CO2 routine maintenance as per requirmnt? not much cross que and no NA que.....only heard ans an said ok. Func4b boiler water level low!!! your action.... after explaining him what action i will take...he started his drill machine..... he asked which engines u hv done and their rvrsing procedure ?? RTA MAN reversing explained nxt que- what if the lost motion clutch is not working.....said inside hydraulic pressure is not building.....how will u reverse the engine? a long pause...i was thinking ...he was waiting how to calculate BHP..... he did not accpt only P=pLAN....he wants it as per manual which includes this formula but has some more calculations.... one guy before me had complete ans but i didnt read it.....its all given in MAN B&W manual with all the formula and values. Func 5 alternator maintenance? then cross que are-How will you measure air gap,,,,,,how much,from where u will measure air gap....port side?? fwd or aft of alternator?? AVR? its function? how to check diode??? Open circuit and short circuit test?? he asked what else trassi askd last time.....i told him AMPmobile (he didint knew it-and told me explain). trickle charging ....he said ok.... he asked me my written result and asked you know latest regulation for Fixed CO2 system?? i said...all the ammendmnts i already told u.....

Its a new ammendmnt?? he gave me a hint......its related to old vesse....what will you do with your co2 system if vessel is more then 20 years old.... didnt knew it......he said ok....u will get all the ammendments in MSC ciculars..i asked him any website....he said 0 idont know....but MSC circulars are distributed to class and authorities when their is new ammendments...contact some1 in class if u know?? i said ok he goes tooo deep in every que.

 ICCP Systems work by taking the shipƞs power, converting it using as a transformer rectifier unit into direct current and impressing this on to the hull through inert anodes strategically positioned on the hull. The current will flow from the inert anodes through the sea water and back to the hull. This is ensured by a sufficiently large dielectric coating applied on the hull around the anode. c  *     "

DYNAMIC WINCH BRAKE TEST Annual operational testing should preferably be done by lowering the empty boat. When the boat has reached its maximum lowering speed and boat enters the water, the brake should be abruptly applied. Five-yearly operational testing should be done by lowering the boat loaded to a proof load of 1.1 times the maximum working load of the winch, or equivalent load. When the boat has reached its maximum lowering speed and before the boat enters the water, the brake should be abruptly applied. OVERHAUL OF ON-LOAD RELEASE GEAR dismantling of hook release units; examination with regard to tolerances and design requirements; adjustment of release gear system after assembly; operational test as per above and with a load according to SOLAS regulation III/20.11.2.3; and Examination of vital parts with regard to defects and cracks.. Test of fire fighting equipments. Fire Fighting Equipments including portable fire extinguishers that exists while the ship is being registered under Indian flag are required to have documentary evidence of having approval of Administration or classification society, who is a member of the IACS and the fire fighting equipment is approved in accordance with the relevant provision of the SOLAS 74 as amended and relevant provision of the FSS Code and applicable IMO Assembly Resolution All fire extinguishers are required to have 100 % spare charges; Shipping companies are required to ensure that the refill of the same make is available on board ship Shipping companies are not able to comply with the requirement of getting one third of the fire extinguishers pressure tested every year. In order to facilitate shipping companies, it has been decided that fire extinguishers may be hydraulically pressure tested during the dry dock once in three years. However, shipping companies are required to ensure that the ships fire extinguishers are properly maintained and kept in satisfactory operating condition at all times Weekly testing and inspections all public address systems and general alarm systems are functioning properly; and Breathing apparatus cylinders do not present leakages. Monthly testing and inspections all firemanƞs outfits, fire extinguishers, fire hydrants, hose and nozzles are in place, properly arranged, and are in proper condition; all fixed fire-fighting system stop valves are in the proper open or closed position, dry pipe sprinkler systems have appropriate pressures as indicated by gauges; sprinkler system pressure tanks have correct levels of water as indicated by glass gauges; all sprinkler system pumps automatically operate on reduction of pressure in the systems; all fire pumps are operated; and all fixed fire-extinguishing installation using extinguishing gas are free from leakage. Quarterly testing and inspections all automatic alarms for the sprinkler system are tested using the test valves for each section; the international shore connection is in proper condition; lockers providing storage for fire-fighting equipment contain proper inventory and equipment is in-proper condition; all fire doors and fire dampers are tested for local operation; and all CO2 bottle connections for cable operating system clips should be checked for tightness on fixed fire-extinguishing installations. Annual testing and inspections all fire extinguishers are checked for proper location, charging pressure and condition; fire detection systems are tested for proper operation, as appropriate; all fire doors and dampers are tested for remote operation; all foam-water and water-spray fixed fire-fighting systems are tested for operation; all foam-water and

water-spray fixed fire-fighting systems are tested for operation; all accessible components of fixed fire-fighting system are visually inspected for proper condition; all fire pumps, including sprinkler system pumps, are flow tested for proper pressures and flows; all hydrants are tested for operation; all antifreeze systems are tested for proper solution; sprinkler system connections from the ship?s fire main are tested for operation. all fire hoses are hydrostatically tested; breathing apparatus air recharging systems checked for air quality; control valves of fixed fir-fighting system should be inspected; and air should be blown through the piping of extinguishing gas systems. Five-year service hydrostatic testing for all SCBA?s cylinders; and control valves of fixed fire- fighting systems should be internally inspected. . If the LSA is of Indian make, the "type approval" shall be granted in accordance with M.S. (LSA) Rules. Application shall be forwarded and thereafter tests will be carried out by the nearest Mercantile Marine Department surveyors. Based on satisfactory compliance with the applicable IMO standards an approval for a period of 5 years shall be granted If the LSA is of foreign make, the applicant will be required to submit necessary authenticated document to the Nautical Adviser for scrutiny and consideration for issue of Letter of Acceptance for that appliance No replacement or substitution shall be permitted. The life rafts of foreign make to which acceptance letter has been issued shall be put up for inspection by the MMD for functional test and necessary certificate shall be issued by the MMD on direction of DGS before the same is placed on board Indian ships Letter of Acceptance as mentioned in para (c) shall be issued for a limited period, maximum of 5 years subject to intermediate verification of 2 1/2 year + 3 months. The foreign manufactures of LSA, who seek "Letter of Acceptance", shall clearly nominate only one representative in India who shall be responsible for such equipments. . LSA service stations where inflatable LSA are periodically serviced must have approval from the Directorate General of Shipping. For self certification, the servicing of Life raft shall be carried out at Service Station approved by D.G. Shipping. Such approved Service Station should also have necessary approval from the manufacturer. In all other cases the servicing may be carried out in the presence of a surveyor from the Mercantile Marine Department. Other inflatable LSA of foreign-make will be serviced in the presence of a surveyor from the Mercantile Marine Department. The life raft of the Indian manufacture shall not be serviced by any other service station unless until such service station has an authorization from manufacturer. In such cases, the servicing of the life raft shall be done under the supervision of MMD surveyor. In the cases where the Indian manufacturer has not authorised any service station for servicing of his life raft in any Indian port, the servicing in such port can be undertaken by any service station as per the customer s wish under the supervision of MMD surveyor. The purpose of a Voyage Data Recorder (VDR) and Simplified Voyage Data Recorder (S-VDR) is to maintain and store (in a secure and retrievable form) information concerning the position, movement, physical status, command and control of a vessel over the period leading upto and following an incident / casualty. The information contained in the VDR / S-VDR is to be retrieved and used during the subsequent investigation. For a vessel operating in shallow waters, cost of recovery of fixed VDR recording medium may not be very expensive. However, in case a vessel is lost in deep waters, the cost of recovery of the recording medium may be prohibitive and at times not feasible at all. In view of the foregoing, it has been decided that all Indian ships shall install the float-free variety of the VDR / S-VDR. However, if the shipowner has already installed the fixed type of VDR or it is not possible to install the float-free VDR meeting full requirements of the IMO Resolution, they shall ensure that an additional float-free arrangement may be made to retrieve the following information: Operators should periodically check the condition of igniters and flame scanners, to ensure that they are in good working order, Automatic fuel oil shut offs should, as a routine, be tested to ensure that the fuel valves operate efficiently for fault conditions (e.g. flame failure and combustion air failure). Burners should be lit with fuel oil at the minimum firing rate compatible with flame establishment and operators should not attempt to light a burner immediately after its flame failure. Whenever any machinery is required to be operated on emergency mode, Chief Engineer Officer must be informed, who in turn must give specific instructions for such an operation and take immediate steps to restore the normal mode. Particular attention is drawn to the need to purge the furnace and gas passages with air following flame failure or ignition failure however short the period of failure or prior to any lighting up operation. The sensors should be capable of being located either in the aft part of each cargo hold or in the lowest part of the spaces other than cargo holds to which these requirements apply. The systems of detecting water level should be capable of continuous operation while the ship is at sea. An alarm, both visual and audible, activated when the level of water at the sensor reaches the main alarm level, an alarm both visual and audible must be activated indicating increasing water level in a cargo hold. The indication should identify the space and the audible alarm should not be the same as that for the per-alarm level. For compartments other than cargo holds: An alarm both visual and audible, indicating the presence of water in a compartment other than a cargo hold when the level of water in the space being monitored reaches sensor. The visual and audible characteristics of the alarm indication should be the same as those for the main alarm level in a hold space.The detector indicating the water level should be capable of activating to an accuracy of + 100 mm. The part of the system which has circuitry in the cargo area should be intrinsically safe The visual indication should be capable of remaining visible until the condition activating it has returned below the level of the relevant sensor. The visual indication should not be capable of being extinguished by the operator. The audible indication should be capable of being muted by the operator. Time delays may be incorporated into the alarm system to prevent spurious alarms due to sloshing effects associated with ship motions.Overriding indication and alarms for the detection systems installed only in tanks and holds that have been designed for carriage of water ballast. Cancellation of the override condition and reactivation of the alarm should automatically occur after the hold or tank has been de-ballasted to a level below the lowest alarm indicator level. The water level detector system should be capable of being supplied with electrical power from two independent electrical supplies. Failure of the primary electrical power supply should be indicated by an alarm.

SSAS what and how ? The SSAS should be documented in the Ship Security Plan. The location of activation points should be specified in the plan and may form a part of the Confidential Section of the plan. It is advised that such information shall be known to the Master, Ship Security Officer and other ship personnel as may be decided by the Master and the SSO. The dedicated equipment used for transmission of Security Alert should not be used for any other routine communication. The system should have the main source of electrical power and a backup source, which may include emergency source or independent supply. However, an uninterruptible power supply (UPS) or such similar device may also be considered as an alternate source of power. All Indian Ship owners, Company Security Officers, Masters and others concerned may please note that the SSAS test is to be carried out in the "LIVE" mode only. How to test SSAS? The standard procedure for testing of Ship Security Alert System is as follows: 1. E-mail DG Commcentre the following information at least three hours in advance when requesting for a test : a) Name of the vessel and its present position b) Intended date and time (UTC) and IST of the test. 2. The DG Commcentre will acknowledge confirming the conduct of the test. It may be noted that SSAS tests with other ship/s may have already been scheduled at the proposed time, in which case, the DG Commcentre would advise the earliest suitable time for the conduct of the test. 3. The ship staff may then carry out the SSAS test as per schedule, first from Location 1. 4. The CSO/ Master shall confirm by phone whether the Alert has been received by DG Comm centre. DG Comm centre will then advise if all details provided in the alert are correct, or otherwise. 5. If all details received are correct, DG Comm centre will advise to reset the alert and then proceed to test from Location 2 6. When testing from Location 2, WAIT FOR about 30 minutes for alert to go to Level 3. 7. Call DG Comm centre to confirm whether alert Level 3 has been received. 8. DG Comm centre will confirm whether all is OK, or otherwise. If all is OK, DG Comm centre will advise the CSO/ Master to reset the system. 9. After resetting the system, the CSO/ Master to send an email to DG Comm centre stating that the "SSAS test has been completed and all subsequent alerts may be treated as true alerts." Request for compliance may be made immediately upon satisfactory completion of the test, and not after several days, 10. Comm centre will then revert compliance by email if tests were OK or advise further testing/ rectification, as required. '

The amendments to MARPOL Annex VI Regulations for the prevention of air pollution from ships, add a new chapter 4 to Annex VI on Regulations on energy efficiency for ships to make mandatory the Energy Efficiency Design Index (EEDI), for new ships, and the Ship Energy Efficiency Management Plan (SEEMP) for all ships. Other amendments to Annex VI add new definitions and the requirements for survey and certification, including the format for theInternational Energy Efficiency Certificate. The regulations apply to all ships of 400 gross tonnage and above and are expected to enter into force on 1 January 2013. However, under regulation 19, the Administration may waive the requirement for new ships of 400 gross tonnage and above from complying with the EEDI requirements. This waiver may not be applied to ships above 400 gross tonnage for which the building contract is placed four years after the entry into force date of chapter 4; the keel of which is laid or which is at a similar stage of construction four years and six months after the entry into force; the delivery of which is after six years and six months after the entry into force; or in cases of the major conversion of a new or existing ship, four years after the entry into force date. The EEDI is a non-prescriptive, performance-based mechanism that leaves the choice of technologies to use in a specific ship design to the industry. As long as the required energy-efficiency level is attained, ship designers and builders would be free to use the most cost-efficient solutions for the ship to comply with the regulations.

The SEEMP establishes a mechanism for operators to improve the energy efficiency of ships. Promotion of technical co-operation The new chapter includes a regulation on Promotion of technical co-operation and transfer of technology relating to the improvement of energy efficiency of ships, which requires Administrations, in co-operation with IMO and other international bodies, to promote and provide, as appropriate, support directly or through IMO to States, especially developing States, that request technical assistance. It also requires the Administration of a Party to co-operate actively with other Parties, subject to its national laws, regulations and policies, to promote the development and transfer of technology and exchange of information to States, which request technical assistance, particularly developing States, in respect ofthe implementation of measures to fulfil the requirements of Chapter 4. Work plan agreed The MEPC agreed a work plan to continue the work on energy efficiency measures for ships, to include the development of the EEDI framework for ship types and sizes, and propulsion systems, not covered by the current EEDI requirements and the development of EEDI and SEEMP-related guidelines. Commenting at the close of the session, on the outcome of MEPC, IMO Secretary-General Efthimios E. Mitropoulos expressed satisfaction at the many and various significant achievements with which the session should be credited. ƠAlthough not by consensus ƛ which of course would be the ideal outcome ƛ the Committee has now adopted amendments to MARPOL Annex VI introducing mandatory technical and operational measures for the energy efficiency of ships. Let us hope that the work to follow on these issues will enable all Members to build the consensus that evaded the Committee this time,ơ he said. Marine Environment Protection Committee (MEPC) ƛ 62nd session: 11 to 15 July 2011 IMO environment meeting completes packed agenda IMO adopted amendments to the International Convention for the Prevention of Pollution from Ships (MARPOL) to designate the United States Caribbean Sea as a new emission control area (ECA); to designate the Baltic Sea as a Special Area with respect to pollution by sewage from ships; and to adopt a revised Annex V related to the control of garbage, at the 62nd session of the Marine Environment Protection Committee (MEPC), which met from 11 to 15 July 2011 at the IMO Headquarters in London. IMO also adopted mandatory measures to reduce emissions of greenhouse gases (GHGs) from international shipping (see press briefing 42/2011 http://www.imo.org/MediaCentre/PressBriefings/Pages/42-mepc-ghg.aspx ). The MEPC also designated the Strait of Bonifacio as a Particularly Sensitive Sea Area (PSSA) and adopted the first-ever international recommendations toaddress biofouling of ships, to minimize the transfer of aquatic species. In other matters, the MEPC approved a number of ballast water management systems and adopted guidelines related to the implementation of both the ballast water management and ship recycling Conventions.

Energy efficiency measures adopted Mandatory measures to reduce emissions of greenhouse gases (GHGs) from international shipping were adopted by Parties to MARPOL Annex VI represented in the MEPC (see Briefing 42/2011 http://www.imo.org/MediaCentre/PressBriefings/Pages/42-mepc-ghg.aspx). The MEPC agreed to the terms of reference for an intersessional working group on energy efficiency measures for ships, scheduled to take place in February/March 2012, tasked with: further improving, with a view to finalization at MEPC 63, draft Guidelines on the method of calculation of the EEDI for new ships; draft Guidelines for the development of a SEEMP; draft Guidelines on Survey and Certification of the EEDI; and draft interim Guidelines for determining minimum propulsion power and speed to enable safe manoeuvring in adverse weather conditions; considering the development of EEDI frameworks for other ship types and propulsion systems not covered by the draft Guidelines on the method of calculation of the EEDI for new ships; identifying the necessity of other guidelines or supporting documents for technical and operational measures; considering the EEDI reduction rates for larger tankers and bulk carriers; and considering the improvement of the guidelines on the Ship Energy Efficiency Operational Indicator (EEOI) (MEPC.1/Circ.684). United States Caribbean Emission Control Area adopted Following approval at its last session, the MEPC adopted MARPOL amendments to designate certain waters adjacent to the coasts of Puerto Rico (United States) and the Virgin Islands (United States) as an ECA for the control of emissions of nitrogen oxides (NOX), sulphur oxides (SOX), and particulate matter under MARPOL Annex VI Regulations for the prevention of air pollution from ships. Another amendment will make old steamships exempt from the requirements on sulphur relating to both the North American and United States Caribbean Sea ECAs. The MARPOL amendments are expected to enter into force on 1 January 2013, with the new ECA taking effect 12 months later. Currently, there are two designated ECAs in force under Annex VI, the Baltic Sea area and the North Sea area, while a third, the North American ECA, which was adopted in March 2010 with entry into force in August 2011, will take effect in August 2012. Other Annex VI issues The MEPC adopted Guidelines for reception facilities under MARPOL Annex VI and Guidelines addressing additional aspects to the NOx Technical Code 2008 with regard to particular requirements related to marine diesel engines fitted with selective catalytic reduction (SCR) systems. The MEPC approved, for future adoption, draft amendments to the NOxTechnical Code 2008, relating to engines not pre-certified on a test bed and toNOxreducing devices. It also agreed terms of reference for the review of the status of technological developments to implement the Tier III NOx emission standard. Black Carbon measures to be further considered The MEPC agreed a work plan on addressing the impact in the Arctic of Black Carbon emissions from ships and instructed the Sub-Committee on Bulk Liquids and Gases (BLG) to: develop a definition for Black Carbon emissions from international shipping; consider measurement methods for Black Carbon and identify the most appropriate method for measuring Black Carbon emissions from international shipping; investigate appropriate control measures to reduce the impacts of Black Carbon emissions from international shipping in the Arctic; and submit a final report to MEPC 65 (in 2014). Black Carbon is a strongly light-absorbing carbonaceous aerosol produced by incomplete combustion of fuel oil and is considered a constituent of primary particulate matter, as distinguished from secondary particulate matter pollutants formed in the atmosphere from sulphur dioxide emissions. In addition to harmful human health effects associated with exposure to particulate matter, Black Carbon has effects on climate change. When deposited on snow and ice in the Arctic and lower latitudes, it darkens light surfaces and absorbs energy, causing snow and ice to melt. Annex IV (Sewage) Baltic Special Area adopted The MEPC adopted amendments to MARPOL Annex IV Prevention of pollution by sewage from ships to include the possibility of establishing ƠSpecial Areasơ for the prevention of such pollution from passenger ships and to designate the Baltic Sea as a Special Area under this Annex. The amendments are expected to enter into force on 1 January 2013. Revised Annex V (garbage) adopted The MEPC adopted the revised MARPOL Annex V Regulations for the prevention of pollution by garbage from ships, which has been developed following a comprehensive review to bring the Annex up to date. The amendments are expected to enter into force on 1 January 2013. The main changes include the updating of definitions; the inclusion of a new requirement specifying that discharge of all garbage into the sea is prohibited, except as expressly provided otherwise (the discharges permitted in certain circumstances include food wastes, cargo residues and water used for washing deck and external surfaces containing cleaning agents or additives which are not harmful to the marine environment); expansion of the requirements for placards and garbage management plans to fixed and floating platforms engaged in exploration and exploitation of the sea-bed; and the addition of discharge requirements covering animal carcasses. PSSA for Strait of Bonifacio designated The MEPC agreed to designate the Strait of Bonifacio as a Particularly Sensitive Sea Area (PSSA), following its approval in principle at the last session, and consideration of associated protective measures by the Sub-Committee on Safety of Navigation (NAV) in June 2011. The MEPC also agreed, in principle, to designate the Saba Bank in the Caribbean Sea as a PSSA, noting that the Netherlands would submit detailed proposals for associated protective measures to the NAV Sub-Committee, which would provide recommendations to the Committee with a view to final designation of the PSSA at MEPC 64 in October 2012. Biofouling guidelines adopted The MEPC adopted the first set of international recommendations to address biofouling of ships, to minimize the transfer of aquatic species. The Guidelines for the

control and management of ships' biofouling to minimize the transfer of invasive aquatic species will address the risks of introduction of invasive aquatic species through the adherence of sealife, such as algae and molluscs, to shipsƞ hulls. Research indicates that biofouling is a significant mechanism for species transfer by vessels. A single fertile fouling organism has the potential to release many thousands of eggs, spores or larvae into the water with the capacity to found new populations of invasive species such as crabs, fish, sea stars, molluscs and plankton. Minimizing biofouling will significantly reduce the risk of transfer. Guidelines on recycling of ships adopted The MEPC adopted the 2011 Guidelines for the development of the Ship Recycling Plan as well as updated Guidelines for the development of the Inventory of Hazardous Materials, which are intended to assist in the implementation of the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships, adopted in May 2009. The Committee encouraged Governments to ratify the Convention, which has been signed, subject to ratification, by five countries, and to review the programme of technical assistance aimed at supporting its early implementation. Ballast water management systems approved The MEPC granted final approval to two and basic approval to seven ballast water management systems that make use of active substances, following the recommendations of the fifteenth, sixteenth and seventeenth meetings of the Joint Group of Experts on the Scientific Aspects of Marine Environment Protection (GESAMP) Ballast Water Working Group, which met in December 2010, February/March and May 2011, respectively. The MEPC also adopted the Procedure for approving other methods of ballast water management in accordance with regulation B-3.7 of the Ballast Water Management Convention, which will open the door for new methods and concepts to prevent risks arising from the transfer of invasive species, provided that such methods will ensure at least the same level of protection of the environment as set out in the Convention and are approved in principle by the MEPC. Guidance on scaling of ballast water management systems was also approved. The MEPC reiterated the need for countries to ratify the International Convention for the Control and Management of Ships' Ballast Water and Sediments, 2004, to achieve its entry into force at the earliest opportunity. To date, 28 States, with an aggregate merchant shipping tonnage of 26.37 per cent of the world total, have ratified the Convention. The Convention will enter into force twelve months after the date on which not fewer than 30 States, the combined merchant fleets of which constitute not less than 35 percent of the gross tonnage of the worldƞs merchant shipping, have become Parties to it. Guidelines for the carriage of blends of petroleum oil and bio-fuels approved The MEPC approved Guidelines for the carriage of blends of petroleum oil and bio-fuels, which set out carriage and discharge requirements for bio-fuel blends containing 75% or more of petroleum oil (they are subject to Annex I of MARPOL); bio-fuel blends containing more than 1% but less than 75% of petroleum oil (subject to Annex II of MARPOL); and bio-fuel blends containing 1% or less petroleum oil (also subject to Annex II of MARPOL). FSA environmental risk evaluation criteria endorsed The MEPC endorsed environmental risk evaluation criteria, for inclusion in theGuidelines for Formal Safety Assessment (FSA) for use in the IMO rule-making process, subject to approval by the Maritime Safety Committee (MSC). Implementation of the OPRC Convention and OPRC-HNS Protocol The MEPC also discussed the report of the OPRC-HNS Technical Group, which met for its twelfth meeting the week prior to the MEPC session to progress several matters, including the development of guidelines and manuals, on marine pollution preparedness and response. 2 hours ago · Like · · Subscribe

   / *       *     The only basic difference between synthetic oil and mineral oil, apart from its manufacture and origin, is the molecular and particulate structure of both the lubricants. Synthetic oil being a perfected product, has a very even and uniform structuring of molecules and particulates. On the other hand, mineral oil contains uneven and less uniform molecules as compared to synthetic oil. Now, when the car, engine, piston and piston block is new, it is always advisable to use, mineral oil. The uneven molecular structure of mineral oil makes the uneven surfaces of the components and auto parts rub with each other and erode, thus making the surface even and smooth . This is very useful, as the young components of the engine get into shape and adapt to the mechanism. As the engine grows older, the components, get into shape and start running swiftly without any friction. This is where one should start using synthetic oil. This oil basically keeps the engine in shape and helps in increasing the durability of the engine. ?3.
