Training Procedures Section 1 Training Procedures

Crane Operator OJT Module Training Procedures Sheet Objectives Upon completion of this module, the participant should be able to: 1. demonstrate a clear understanding of the role and responsibilities of Transocean crane operators, and 2. perform basic crane operator tasks safely and competently. Training Procedure Completing the crane operator module should take about twelve working weeks, depending on the effort put in. The mandatory task list is the basic tool for recording progress, and each item on the list shall be completed before participants can receive a module certificate. The task list evaluation guide in this assessor’s guide is to help you assess the competence of the participants. Some flexibility is permitted, but you must be thoroughly satisfied that the level of skill and knowledge demonstrated by each participant is consistent with the objectives of this OJT module. Only when you believe that a participant has truly achieved the required skill level and knowledge required by each task, should you sign off on it. The suppporting self-study DVD-ROMs, CD-ROMs, books and workbook questions helps participants understand the tasks. The use of these tools is voluntary. Many training participants will find the tools very helpful in providing fundamental knowledge. You can customize the task list according to the requirements of your particular rig. A blank section is provided for you to add additional tasks you feel are important and want participants to perform. You cannot, however, delete tasks, except where they do not apply to your rig. When the participant completes the task list requirements to your satisfaction, and has successfully completed the computergenerated final test, complete and sign a completion notification form (CNF). Also, ensure that the participant fills in the employee comments section. Then, forward the completed and signed CNF to the regional training center. After receiving the CNF, the training center will complete the participant in the Training Management System. The RSTC will then be able to print a module certificate from the Training Management System. Keep the completed task list on file at each participant’s assigned location. The training file shall be transferred when the participant is transferred.

Section 2 Task List Evaluation Guide

Task List Evaluation Guide

Crane Operator Task List Evaluation Guide 1.

Describe how the OJT system works and the supervisor’s role in it. Ask participants to explain the OJT system and how it works. The OJT task list is the core of the training system and reference tools are provided to support the hands-on-training if needed. Supervisors play a key role implementing the training. Supervisors are, as part of their ongoing duties, expected to continue providing guidance and on-the-job training to crew members. They monitor and track the progress of the participants with the help of the task list and appraisal guidelines. They are required to teach and instruct the participants. The OJT competency based system is a self-paced program that trains and measures a participant’s skills and knowledge required in each job category or function. The OJT system is a tool for self-development and career progression. It is designed to ensure that the participant is exposed to a majority of the important occurrences relative to the particular job category or function. It consists of a combination of practical work on the rig and self-study. The mandatory tasks are supported with optional training tools that consist of books, manuals, interactive CD-ROMs, and films on DVD-ROMs. Open-book questions are also provided. Instruction and evaluation of the training participants is the responsibility of the immediate supervisor(s). Participants must demonstrate competency in each task before the supervisor signs it off as completed. This method of assessment ensures a demonstrated ability from participants as they gain new knowledge and skills required for the job function. All tasks must be completed to the supervisor(s) satisfaction before they are eligible to complete a final computergenerated test. Ask questions such as: “What are the components of the OJT system and how is it implemented?” Module booklets, reference books, and reference software are procured in the conventional manner referencing the order list on the Corporate Training website or EMPAC/TOPS Houston Procurement website. The supervisor gives the module booklet to the participant who follows the self-paced task list. Besides hands-on learning, training tools are also used to help the participant gain knowledge on the tasks. Supervisors assess participants as they perform the tasks. The OJT Modules Assessor’s Guide is provided to guide the supervisors through the assessment process as required. All tasks must be completed to the supervisor’s satisfaction. Workbook questions also support the tasks. The supervisor should evaluate the workbook answers. The participant must successfully complete the final computer-generated test after all other training requirements are completed. The completion notification form (CNF) is completed by the supervisor and participant and sent to the regional training center for recording in the training database (TMS). A certificate is issued to the participant. When the participant is transferred to another location, the task list / training records are also transferred.

2.

Describe the physical requirements to work as a crane operator. Participants should describe the minimum physical requirements to work as a crane operator. Requirements encompass the following: age, vision, hearing, fitness, depth perception, and health history. A crane operator should be at least 18 years of age. The operator should have at least 20/30 snellen vision in one eye and 20/50 in the other with or without glasses, should have the ability to perceive depths accurately, and be able to distinguish red, green, or yellow regardless of the position of the colors. It is important that the operator has adequate hearing with or without a hearing aid. The operator must be reasonably fit to carry out duties. The operator must be able to judge distances, heights, and clearances accurately. The operator must have no history of mental or physical disabilities. Reference CD-ROM 61.04010.

3.

Demonstrate good housekeeping practices to ensure your areas of responsibility are maintained in a clean, tidy, and hazard-free manner. Observe participants practicing good housekeeping in and around the cranes on their rig. Ask a question such as: “Why is it necessary to keep your crane and the immediate area around it clean, tidy, and free of hazards?” Debris and trash in the cab can interfere with proper operation of crane controls; dirty windshields can obscure vision; tools not properly stowed can become lost or broken; dirt and trash can contaminate lubricants.

Crane Operator Task List Evaluation Guide 4.

Describe the type of crane(s) on your rig. Participants should describe the types of crane(s) used on their rig. Ask questions such as: “What type of crane is on this rig?” “What is its rated capacity at 24-foot radius?” “What is its maximum radius and capacity?” “What are the main types of cranes used on Transocean rigs?” Ask the participant to give the maximum load at various locations on the rig (i.e. V-door). Reference DVD-ROM 20.0124 and CD-ROM 61.04010.

5.

Demonstrate prestart checks, start-up procedures, preoperational checks, checking of crane controls, and routine checks made during normal crane operations. Participants should demonstrate the prestart checks, start-up procedures, preoperational checks, crane control checks, and routine checks they should make during normal crane operations. Ask questions such as: “When you approach the crane to make a lift, what is the first thing to check?” Ensure that the boom is in good operating shape and that it cannot inadvertently come into contact with any part of the rig. Then visually check the swing circle bolts as you go up to the crane. Also look for oil spills on the walkway under the engine. Check the condition of the ladders. “What is the last thing you should check before starting the engine?” Check that all of the control levers are in the neutral position and the brake set is on. “After starting the engine, what is the very first thing to check?” Check for any strange noises in the engine house, then check the gauges in the cab and on the engine or drive train. Reference DVD-ROM 20.0425 and CD-ROM 61.04010.

6.

Demonstrate the use of crane controls during a routine crane operation. Participants should plan where the load will be placed, check for obstacles, check the load radius, and know which quadrants the upperworks will rotate in. They should demonstrate how to swing the boom 90 degrees to the left or right with a load, while not allowing the load to sway. Ease the swing lever in to start the load moving and then a little faster to keep up with the load, then slow down to slow the load. To stop, quickly swing to position vertically above where the load is, thus stopping the load at 90 degrees from the start. Ask a question such as: “What is the most important thing to remember about lifting a heavy load?” Raise the boom as well as the main hook to compensate for wire rope stretch and boom flexing. Keep the load within the SWL radius of the crane’s boom. Do not raise a heavy load using only the main block, because the load can swing away from the crane and possibly overload the boom by being out of the SWL radius for that weight. Reference Orientation for Offshore Crane Operations book 2.50820, DVD-ROM 20.0425, and CD-ROM 61.04020.

7.

Demonstrate prelift and postlift procedures. Ask for a demonstration of prelift and postlift procedures. The participants should wait for the banksman’s signal prior to operating controls. Participants should keep the hook directly over the top of the load to be lifted and tighten the slings slowly. They should then stop until all the roustabouts are out of the way before the lead roustabout gives the signal to raise the load. No one should be directly under the load. Participants should land the load correctly on wood or packing, lower the hook enough to allow the roustabouts to take the slings off, and then raise the hook above head height and allow the roustabouts to remove the slings from the load. Reference DVD-ROM 20.0425 and CD-ROM 61.04020.

Demonstrate normal crane shutdown procedures. Observe participants routinely shutting down the crane. Always place the crane boom onto the boom rest. Then make sure that the clutch is out, the brake set is on, and the swing hand-brake is on. Reference DVD-ROM 20.0425 and CD-ROM 61.04020.

9.

Show how to use the manufacturer’s manual in the crane cab. Participants should demonstrate that they are familiar with using the crane manual in the cab. Ask questions on each section of the manufacturer’s manual such as: “Where would you find information on the grease fitting locations on the boom tip?” “In which section would you find load chart information?” Reference DVD-ROM 20.0122 and CD-ROM 61.04020.

10. Demonstrate proper use of radio equipment and communication techniques. Give participants a hand-held radio and ask them to check if the radio is on the right channel for the rig and workboats (or deck crew). Participants should then demonstrate the sequence to get the correct channel and lock on. Observe the standard protocol for radio use, including how to initiate and terminate the radio conversation. Ask which channels to use and not to use and why. Observe battery charging procedures. Reference DVD-ROM 20.0122. 11. Assist the drill crew in moving drilling tools between the deck and the drill floor. Observe participants moving drilling tools between the deck and the drill floor. They should hold THINK drill at the work site with the crew before any lifting is done. Check that a banksman is on site during the lift(s). Reference A Primer of Offshore Operations book 1.10030, DVD-ROM 20.0122, and CD-ROM 61.04020. 12. Off-load and back-load a supply vessel under calm weather conditions. Observe participants off-loading and back-loading a boat under supervision. Participants should explain vessel specific criteria for supply boat operations. Ask questions such as: “What is the boom angle limit of the crane when making a lift off a boat?” “What is the safest way to lift a load off or put a load down on a workboat?” Have the correct slings on the crane, swing over the side of the rig and lower the hook down over the water to the side of the boat. Wait for the boat to back in. Ensure that the hook is directly over the load before lifting and tighten up the slings. Always take the load off when the boat is on the rise and then swing off the boat to the side. Bring the load up to the deck and land it. When going down with back-loading, ensure the load is lowered over the water until it is about 15 feet above the boat’s deck level. Then swing over the boat and allow the crew to straighten up the load with the tag lines. Land it as the boat goes down. Reference A Primer of Offshore Operations book 1.10030 and DVD-ROM 20.0425.

Crane Operator Task List Evaluation Guide 13. Demonstrate a non-routine lift such as a dual lift involving two cranes. Observe participants performing a dual crane lift such as laying the slip joint out. This task is to be done under strict supervision, and with an experienced operator at the second crane. Do not attempt this task until you are satisfied that participants are able to complete it safely. Participants must first refer to rig specific procedures for this type of operation. Ensure that the crane operator is directly involved with creating and reviewing the procedures. This operation may also include the use of tuggers in conjunction with crane. Reference DVD-ROM 20.0425. 14. Show how to check the anti-two block and travel limiting devices. Ask participants to check anti-two block limits. The limits should be checked with the crane in a position where the limits can be seen to stop as they are tested. On jackup rigs, participants should carefully swing towards a leg and test whether swing motion can be safely stopped until the boom has been raised high enough to pass inside the leg. Only after the boom is raised should the swing be continued. Reference DVD-ROM 20.0425. 15. Explain the rig specific procedures for cranes during helicopter operations. Ask participants to describe rig specific procedures and communication process to ensure crane operations are shut down during helicopter operations. Ask a question such as: “What should you do if a helicopter is about to land or you suddenly hear the rotors of the chopper?” The crane should be locked up and the operator should be standing at the handrail around the crane engine house, away from the cab and the controls. He should remain in sight of the helicopter pilot. The crane should not be moved until the helicopter has departed the rig and is well away from it. Ideally, participants would place the crane boom in its rest, but this action is not always possible. Reference DVD-ROM 20.0425 and CD-ROM 61.04020. 16. Show how to use the crane log book and describe what should be entered in it. Check the participants’ crane log book. Writing must be clear and easy to read. Ask questions such as: “What should be entered in this log book?” Key events such as the number and types of loads; wire rope change outs, including dates and engine hours; unusual occurrences; anything found wrong during operational checks that could not be fixed; and unusual lifts and how they were rigged. “What should not be recorded in the log book?” Any small item that is on the pre- or post operational check lists, anything that is part of the daily PMS checks that was fixed (unless it was an unusual occurrence), and such routine procedures as filling of tanks or greasing. Reference DVD-ROM 20.0122.

Crane Operator Task List Evaluation Guide 17. Communicate effectively with the deck crew, coworkers, and supervisors. Observe participants effectively communicating with the roustabout crew. Ask questions such as: “What is the last job that you assigned to each one of the roustabouts and maintenance roustabouts?” “What are each of the roustabouts doing right at this moment?” Reference DVD-ROM 20.0122 and CD-ROM 61.04020. 18. Show how to conduct a THINK drill at the site where the task will be performed. Observe participants conducting a THINK drill at the work site. Participants should ensure that all concerned roustabout crew members are involved and incorporate suggestions into the work plan. They should also ensure that all safety issues are addressed, all contingency planning is communicated, and key personnel are identified to the group. Assignments and responsibilities must be clearly communicated and understood by each person involved. Ask for an explanation of the purpose of THINK drills. It fully explains to the crew what the job entails and delegate specific tasks to each crew member. It also points out any potential hazards. Reference DVD-ROM 20.0122 and CD-ROM 61.04020. 19. Show how to organize the rig deck area for efficient operations. Ask questions such as: “Where are the walkways; escape routes; routes to the lifeboats, life rafts, and life rings; and routes to the safe briefing areas?” “Where are the fire extinguishers and emergency escape doors (such as at the rear of the logging unit)?” Observe participants’ work areas and ensure that they have not stored anything at or near the crane that blocks safety routes or access to equipment. Observe participants organizing crane loads. Reference DVD-ROM 20.0122. 20. Give a thorough handover briefing to the relief crane operator. Observe and listen to participants during a handover briefing. Ensure that the briefing is thorough and covers situations the relief operator needs to know about. Also, check participants’ handover notes and ask a specific question about these notes. Refer to SMS for specific handover requirements. Reference DVD-ROM 20.0122. 21. Complete a work permit for a non-routine operation. Check the completed safe work permit. Ask participants to name five situations when a safe work permit is required. Expect responses such as: 1) when lifting personnel in a work basket, 2) when transferring personnel to and from boats in a personnel basket, 3) when setting up heavy-lift test equipment, 4) when rigging up or rigging down a BOP or slip joint, 5) when doing PMS on a lifeboat and the boat is hung off on safety pendants, 6) during ROV and diving operations, 7) when lifting over a production zone, 8) when lifting near an overhead obstruction, and 9) when conducting an overload test.

Rev. 02: January 2005

Page: 2.5

Crane Operator Task List Evaluation Guide Ask questions such as: “Why is a work permit required?” To control certain types of work that are identified as potentially hazardous. It is also a means of communication between site management, rig supervisors, operators, and those who carry out the work. “Where are the permits posted and what happens when the job is finished?” They are posted on the specific notice board and all copies are signed by the supervisor of the job and the OIM; they remain on file for one year. Reference DVD-ROM 20.0122. 22. Perform the daily, weekly, and monthly service of the crane and associated components according to the PMS program. Observe participants performing a PMS task on the crane. Also refer to any other PMS weekly or monthly task and ask participants to explain what, why, and how it must be done. Ask when a permit is required while carrying out preventive maintenance. For example, during a load test, or when the crane operator must go out to the boom point while the boom is in the rest. Ask questions such as: “Where are the PMS files stored?” “Where would you go for reference if you discover a difference between last month’s PMS figures and this month’s figures?” Participants, as operators, should be on site to assist the mechanic or electrician when service is performed on the crane. Reference DVD-ROM 20.0424 and CD-ROM 61.04010. 23. Show how to handle common maintenance problems such as hydraulic oil leaks, corrosion, fuel contamination, sheave wear, over lubrication, wire rope misspooling, cab condition, and engine overheating. Make spot checks on items such as the wire rope drum spooling, engine house condition, and cab condition. Observe participants cleaning oil from the hoses in search for oil leaks, listening for any air leaks, and checking the fuel-oil cap for a good seal. The hydraulic-oil and fuel-oil levels should be checked. Ask if there are any ongoing problems with the crane. Reference DVD-ROM 20.0424 and CD-ROM 61.04010. 24. Show how to use a load capacity chart and how crane capacity is affected by boom length, angle, and load radius. Ask a question such as: “How do you measure the crane’s boom radius?” The boom radius is measured from the boom foot pins horizontally to the radius of the main block. The working radius is measured from the center of rotation to the radius of the main block. When the boom length equals the working radius, that is the maximum SWL radius allowed. Refer to the crane’s load chart and ask participants to select the maximum weight that can be picked up with the boom angle at, say, 69 degrees. The point is, if the load chart shows 70 degrees and 65 degrees as the closest to 69 degrees, participants must use the figures for 65 degrees. Interpolation is not permitted. Reference Orientation for Offshore Crane Operations book 2.50820, DVD-ROM 20.0425, and CD-ROM 61.04010.

Rev. 02: January 2005

Crane Operator Task List Evaluation Guide 25. Explain how the center of gravity of a load affects sling placement and correctly sling a load with an offset center of gravity. Ask participants to explain how COG affects sling placement and then observe them correctly sling a load that has an offset COG. Ask questions such as: “How does the center of gravity affect sling placement?” “Why isn’t the slip-joint picked up with two slings of the same length in the middle?” The center of gravity of the load is not in the middle but rather towards the heavy top end. Observe an offset load being lifted. Reference DVD-ROM 20.0425 and CD-ROM 61.04020. 26. Explain operating limits of the crane including lifting capacity, operating speed, weather conditions, and rig motion, and show where to find this information. Participants should explain that the whip line is only rated for a certain amount of weight within the SWL of the wire rope or in some cases the boom, depending on the boom angle. They should also explain the crane specific boom angle limits. Ask questions such as: “Where is the crane’s fulcrum?” Theoretically, the fulcrum is at the point of leverage. On offshore cranes, the fulcrum is at the forward side of the pedestal. “Determine the limiting point (boom or wire rope) when using 6 lines, 4 lines, 2 lines, or a whip line by referencing the load chart.” The limiting point depends on the radius, but there is a point where the point goes from the number of wires to the boom. Most load charts indicate this point. Reference Orientation for Offshore Crane Operations book 2.50820, DVD-ROM 20.0425, and CD-ROM 61.04010. 27. Explain how reeving affects the capacity and speed of the main block and show how to change the number of lines. Observe participants changing the number of lines (with assistance). Ask how reeving affects the capacity and speed of the main block. Given the weight to be raised, the force necessary is divided by the number of wire ropes. The hoisting speed decreases as the number of lines increases. Note that care should be taken to see that the lines do not become crossed, twisted, or fouled. Participants should explain and show how to re-set load indicator for correct number of wire lines when changes are made. Reference Orientation for Offshore Crane Operations book 2.50820, DVD-ROM 20.0425, and CD-ROM 61.04010. 28. Explain the difference between static and dynamic load charts and show how each is used. Ask questions such as: “What is the main factor affecting dynamic lifts?” The sea state. “What is the difference between a static and a dynamic lift?” A static lift is made with no relative motion between the crane and the load about to be lifted. All lifts made on board the rig are static lifts. A dynamic lift is made from a moving workboat deck, when the deck can drop away from the load, causing shock loading to the crane. Dynamic lifts are also made between a floating tender rig and a fixed platform.

Rev. 02: January 2005

Page: 2.7

Crane Operator Task List Evaluation Guide “How do dynamic load charts differ from normal static load charts?” They show wave heights and SWL curves for several significant wave heights. Some dynamic load charts reduce the SWL of a crane by up to 40 percent below that of static or calm conditions. Some dynamic load charts show that a heavier lift can be made at a lower boom angle because the shock load or bounce could throw the crane’s boom over the cab at high angles. Dynamic lifts are a very important part of a crane operator’s duties and if a mistake is made, the shock loading can be as much as three times the weight of the load. Reference DVD-ROM 20.0425 and CD-ROM 61.04010. 29. Describe the common causes of crane-related accidents. Ask participants to describe the common causes of crane-related accidents. Some common causes include poor operator competence, restricted visibility, environmental factors, poor equipment maintenance, poor job evaluation, lack of clear communication, and ignoring START observation data. Ask participants to discuss recent accident analyses and alerts. Reference DVD-ROM 20.0425. 30. Explain the importance of reporting crane accidents or potential accidents as well as defective controls, safety devices, instruments, and other equipment. Ask questions such as: “What could happen if you didn’t report damage to the crane?” Damage or an accident could occur the next time the crane was used. “Would you report damage even if you didn’t do it?” Yes, because a damaged crane is essentially an unusable crane that can be dangerous to life and health. “Why should you report any near miss or potential accidents involving the crane?” A near miss in one instance could be a real accident the next time it occurs. By looking at reports of near misses, future accidents can be prevented by avoiding or alleviating the situation that caused the near miss. Reference DVD-ROM 20.0122. 31. Show how to report a crane overload incident and describe the load test and crane inspection procedures to be performed after an overload. Ask questions such as: “What would you do if you knew the crane had been overloaded?” Report it as soon as possible so it can be checked and a weight test can be arranged. “What sort of damage would you look for if you suspect that the crane has been overloaded?” Cracked paint on the welds of the boom lacing, possible sheave damage, possible wire rope damage (especially at the pickup point), and drum-crushed rope. Reference DVD-ROM 20.0425. 32. Explain the energy isolation system. Ask participants to explain energy isolation and give examples of equipment requiring isolation as it applies to the crane operator’s work. An example of this equipment may include the crane engine. Prior to working on any equipment, all energy sources will be isolated and any stored energy will be released. The OIM will authorize individuals as competent persons for each type of energy isolation. A permit to work is an additional requirement when an isolation certificate is issued for maintenance or repair of a system or component containing energy. In some cases, the task is only hazardous because of the energy. When effective isolation is achieved, the task may no longer be hazardous and, hence, the isolation process controls the risks associated with the energy. The person performing the work will confirm the equipment inoperative by physically trying to operate it. This is done to ensure that prior to working on the equipment, it is rendered safe by releasing any trapped energy (electrical, mechanical, hydraulic, thermal or pneumatic) and that the equipment cannot be energized at either local or remote locations. Reference HS&E Manual 9.30000. Page: 2.8

Rev. 02: January 2005

Crane Operator Task List Evaluation Guide 33. Follow the permit-to-work and lockout and tagout procedures required for a nonroutine maintenance task. Observe participants initiating lockout and tagout procedures for a nonroutine job. Reference DVD-ROM 20.0122. 34. Demonstrate the emergency escape procedure from the cab, use of the escape pack and fire extinguisher, and describe when they should be used. Observe participants stopping and getting out of the crane as quickly and safely as possible. They must land the load safely, take the hook off the slings and raise it out of the way, activate the brake set, put the clutch out, stop the engine, set the handbrake, and leave the cab. Ask participants to explain emergency escape techniques or equipment. Ask questions such as: “What would you do if there was a fire in the engine house?” Land the load, stop the engine, sound the alarm, and try to put out the fire with the extinguisher if practical. “If the fire is out of control in the engine house, how would you escape from the cab of the crane?” “What would you do if the gas alarm sounds?” Land the load, stop the engine, apply all brakes, and go immediately to the safe briefing area. Reference DVD-ROM 20.0122. 35. Show how to use safe weight load indicators (SWLI) and how to set up, adjust, and test the indicator(s) for correct read out. Observe participants adjusting the safe working load indicator and ask questions such as: “What should you do if more (or fewer) lines are on the main block than the number indicated on the SWLI?” Adjust the switch to the number of lines actually in use on the crane. “How do you test the SWLI’s alarms?” Press the test button. Be aware that many types of load indicators are available and some may not have a test button. Reference DVD-ROM 20.0425 and CD-ROM 61.04010. 36. Show how to use safety devices such as up or down limits for the boom, main hoist, whip line, boom pawl limit, hoist brakes, any snatch device to prevent shock loading, swing brake, swing lock, and cab lock. Ask questions such as: “How are the crane boom’s upper and lower limits set?” On the Bucyrus Erie, adjustment pins are on the left inner boom foot pin; On the National, cams are set on an arm that slides with the boom inside the right-side panel in the cab; the arm is under the clutch buttons. When participants are tested, observe them looking up at the limit as the boom approaches it, rather than relying on the horn to warn them that the limit is not working. “How are the whip and main line cut outs, or anti-two-block cut outs checked?” By raising the line slowly onto the limit until it stops. Participants should check each line at least five times and must be watching the cut out every time. Reference DVD-ROM 20.0425 and CD-ROM 61.04010.

Rev. 02: January 2005

Crane Operator Task List Evaluation Guide 37. Show how to use and reset all emergency controls such as emergency stop and emergency load release. Participants should explain and demonstrate crane specific emergency systems and procedures. Ask a question such as: “How do you stop the crane from moving up or down?” By hitting the emergency brake set and pulling the button to reset it. Participants should be able to explain how to use the emergency load release, and how to lower the load with the air-operated foot brake in an emergency without actually depressing the release button. If the load release button is depressed, it can damage the hydraulic motor orifice plates. Reference CD-ROM 61.04010. 38. Show how safety and operational lights are used on the crane and explain why they are important. Observe the use of crane safety and operational lights and ask when and why they are important. To attract the attention of workers around the crane when it is in use; to alert workboats that approach the rig where the cranes are located; and to show helicopter pilots where the cranes are located in relation to the helideck. Reference CD-ROM 20.0122. 39. Describe the specification and construction of all wire ropes used on the crane. Ask a question such as: “What type of wire rope is on the boom (or on the whip line) of the crane?” Participants must reply with the correct diameter, type of construction, type of lay, and type of core. They should know whether the rope is preformed, whether it is galvanized, what grade of steel it is made from, and the length of each of the wire ropes on the crane. Reference Wire Rope Users Manual 10.06010 and DVD-ROM 20.0426. 40. Identify different sling types by design, SWL, dimensions, and other features. Randomly select a sling and ask participants to describe its construction and lay. Also ask where to find the safe working load information or the ID number of the sling. Look on the ferrule at one of the eyes. Sometimes it is stamped as WLL or working load limit instead of SWL. Working load limit is the straight pull limit. In comparison, SWL is the nominal strength that can be applied without damaging or breaking the rope. WLL and SWL are accurate only when the rope is new and in good condition. Ask a question such as: “Where and how should this sling be stored?” Hung up on a rack out of the weather, and lightly oiled for long-term storage. Reference Wire Rope Users Manual 10.06020 and DVD-ROM 20.0125. 41. Show how to maintain an inventory of lifting gear on the rig. Ask questions such as: “Where can I find the test certificate for this shackle?” In the lifting gear register under the shackles section. “What items should be recorded in the lifting gear register?” All lifting gear including slings, shackles, bridles, pad-eyes, chain blocks, hoists, snatch blocks, etc. Reference DVD-ROM 20.0125.

Page: 2.10

Rev. 02: January 2005

Crane Operator Task List Evaluation Guide 42. Explain the crane operator’s role in ensuring that all lifting gear is certified to requirements. Ensure that participants know what to do with new lifting gear when it arrives on the rig. New lifting gear should be recorded in the lifting gear register. Certification number, type, size, and SWL should be entered. Locate a damaged sling and ask participants: “What should you do with this damaged sling?” Record the ID number on the ferrule, destroy the eyes, cut it in half and discard in the scrap metal skip. Then give the number(s) to the barge supervisor to cross off in the lifting gear register. Reference DVD-ROM 20.0125. 43. Explain the lifting gear color-coding system and how records are kept for each item. Ask questions such as: “Why do we have a color-coding system?” “What is the current color code for slings?” “What was the color for last month?” Reference DVD-ROM 20.0125. 44. Show how slings and other lifting gear should be stored correctly. Go with participants to the storage area for slings and inspect for orderliness. Reference DVD-ROM 20.0125. 45. Visually inspect each of the wire ropes used on the crane and explain how to identify damaged wire rope such as abrasion, fatigue, corrosion, bent rope, kinks, irregular wear, diameter change, and mildewing. Ask participants to inspect the crane’s wire ropes and comment on the findings. They should show how to use a sheave gauge. Reference Wire Rope Users Manual 10.06010, DVD-ROM 20.0426, and CD-ROM 61.04010. 46. Demonstrate wire rope lubrication on your rig and explain why pressure lubrication is preferred. Observe participants lubricating wire ropes. Ask questions such as: “What methods are used to lubricate wire rope in the field?” Continuous bath pressure lubrication, dripping, pouring, swabbing, painting, and pressure spraying. “Why is it better to use pressure lubrication instead of simply wiping lubricant on the outside?” The pressure unit actually blows out rust particles and moisture from between the strands and then forces the lubricant in under pressure so that the interior core and exterior rope is thoroughly lubricated. Reference Wire Rope Users Manual 10.06010, DVD-ROM 20.0426, and CD-ROM 61.04010. 47. Explain the rig specific slip-and-cut program and show how to slip and cut the whip and main block lines. Participants should explain the rig specific procedures for inspection and replacement of wire rope. Ask questions such as: “What is the first thing to do when preparing to slip and cut a wire rope?” Check that the rope is not too short to slip and cut and ensure that there are at least five wraps on the drum at all times.

Crane Operator Task List Evaluation Guide “How do you remove old wire from the socket?” Cut off excess wire, leaving about a foot on each side of the wedge. Locate a solid beam and drop the socket and wedge vertically from waist height on to the beam. The wedge should be knocked free from the impact. “How do you bed the wedge into the socket?” It should be done before any clips are put on the wire with a force of about 85 percent of the line’s capacity. Have participants demonstrate the slip-and-cut procedure. Reference DVD-ROM 20.0426. 48. Show how to replace ropes (whip line, main line, boom line, pendants) with proper reeving and drum termination. Ask participants to demonstrate the rule of thumb for finding the correct side of the drum to connect the wire rope. Although this rule doesn’t always apply for particular cranes in some cases, the rule for plain drums should be known by participants. By holding the right or left hand with index finger extended, palm up or down, the proper procedure for applying left- and right-lay rope on a smooth drum can be determined. Refer to page 46 in Wire Rope Users Manual 10.06010. Participants should demonstrate the correct way of connecting a snake to the two ends when pulling new wire rope through the sheaves and back to the drum. They should also be aware that the drum, especially the boom line’s drum, will not accommodate all the old boom wire as the new line is pulled through. It will have to be tied off and the old line removed, and then cut with enough length to reconnect to the drum. Then resume pulling the new wire to the drum, ensuring that at least three wraps of new wire are on the drum before stopping and removing the rest of the old wire. Participants should be able to demonstrate both the wooden block clamp and the sacrificial sling methods for keeping the new wire under tension while placing it on the drum. The roustabout crew should be positioned at the top of the Aframe and in the boom to check the snake as the joined section goes over the sheaves. They should be prepared to stop the motion if it becomes jammed. Have participants demonstrate the use of wire rope clips. The saddle must be on the live working line, with the threads and nuts away from and unable to rub on any part of the working line. Torque nuts evenly. The first clip should be one base width from the dead end of the rope. The second clip should be as near to the loop as possible with the rest of the clips spaced accordingly. Reference Wire Rope Users Manual 10.06010 and DVD-ROM 20.0424. 49. Show how to inspect and identify the SWL of any piece of lifting equipment on your rig such as slings, shackles, lifting bridles, pendants, or spreaders. Participants should find the SWL on all lifting gear, explain what each piece of gear is, and tell what it is used for. 50. Show how to inspect, maintain, and use chains, shackles, hooks, eye bolts, spreader bars, pallet forks, and similar lifting equipment on you rig. Observe participants inspecting, maintaining, and properly using such lifting gear as chains, shackles, hooks, eye bolts, spreader bars, pallet forks, and similar equipment. Participants should explain why homemade or altered equipment is not permitted. They should also explain any restrictions that may be in place relating to persons permitted to conduct inspection. 51. Show how to inspect, maintain, and use web slings, cargo nets, and personnel baskets. Observe participants inspecting, maintaining, and properly using web slings, cargo nets, and personnel baskets. They should also explain any restrictions that may be in place relating to persons permitted to conduct inspection.

Observe participants inspecting, maintaining, and properly using casing hooks, spreader bars, drum lifters, plate clamps, and similar equipment on the rig. Note that only competent crew members are responsible for inspection. 53. Explain the contents of a completed cargo manifest. Review a cargo manifest with participants and ensure that they understand the following. 1) The manifest is in short or metric tons. 2) When multiple grades of drill pipe or casing are to be unloaded, they must know which grades of casing are off-loaded first and why. 3) When loading tubulars, they must check the weights given on the manifest against the weights given in the control room reference book. If there’s a discrepancy, report it to the immediate supervisor. Reference DVD-ROM 20.0122. 54. Show how to plan for unusual loads such as heavy lifts, bulky loads, fragile loads, specialized equipment, and dangerous goods. Check that participants understand which slings are to be used, and that the decks must be cleared and ready. Participants must properly prepare the backload material(s) by securing and positioning before loading onto the workboat. Check if participants are watching for dangerous chemicals and what preparations are made for them. The THINK planning process shall be used as a means of identifying specific dangers and precautions associated with task. Reference DVD-ROM 20.0122. 55. Show how to notify the control room for trim correction while moving load(s) that may affect vessel stability. Ask participants: “Why is it important to tell the control room when a large, heavy lift is to be backloaded, unloaded, or simply moved on the rig?” The trim must be maintained by ballasting. It is especially important to notify the control room when a heavy load is moved on the rig because the weight must be subtracted from where it was and then added to where it is moved. Moving a heavy load makes the difference double the weight moved. Reference DVD-ROM 20.0122. 56. Assist client or service company personnel in moving equipment requiring special handling procedures. Observe participants working with a client or service personnel following all permit to work and safety precautions. Approval for authorization to rig up third-party equipment must be obtained if required. Reference DVD-ROM 20.0122. 57. Explain the rig’s piping color code. Accompany participants to an area of marked piping and ask them to identify specific pipes based on the rig’s color coding system. 58. Show how to line up the rig’s bulk handling system to transfer barite, bentonite, and cement. Ask participants to demonstrate valve line-up to pressure up a P-tank and transfer barite or bentonite to the sack room hopper, or line-up valves at the cement P-tank to pressure up and transfer cement to the cement unit or another P-tank. This task is sometimes rig specific and not performed by the crane operator, but they should nevertheless know the procedure.

Rev. 02: January 2005

Crane Operator Task List Evaluation Guide 59. Show how to line up to load, back load, or transfer liquid mud, fuel, potable water, or drill water. Observe the correct line up of the rig’s systems for various bulk supplies. Check that the particular hoses are color-coded or at least marked with the product name. Ensure that participants trace the hose back to the solid steel piping, especially with the barite and cement hoses. Allow participants to line up the valves to open and close when taking on drill water or fuel oil. 60. Demonstrate procedures for using the personnel basket. Ask participants to fully explain the correct procedure for using the personnel basket. Participants must mention the work permit, PPE, basket condition, and rigging. Observe, under close supervision, the transportation of personnel using the personnel basket. All personnel should have their lifejackets on and stand evenly around the basket with their baggage inside. Lift the basket off the deck just high enough to clear obstructions. Swing evenly overboard and come down steadily over the water at the side of the boat. When the basket is 15 feet above the water, stop and swing the basket over the boat smoothly. Land it gently on a clear area of deck. When coming off the boat, make sure all baggage is secure in the middle of the basket and that all personnel have their lifejackets donned properly. Ensure that the hook of the crane is centered over the basket, and then make the lift on the rise of the boat. Swing overboard when about 15 feet above the boat and raise the basket over water at the side of the boat. Stop just above the deck or helideck height and carefully swing the basket over the deck and land gently. Reference DVD-ROM 20.0425. 61. Show the procedures for using a work basket over the side of the rig. Ask questions such as: “What are the procedures when using a work basket over the side?” Get a safe work permit, hold a THINK drill, get the proper PPE including work vests and safety harnesses, and use twoway radios. Position one man by the handrail at the main deck to directly watch the operation and give signals as required. “What do you do if you lose visual contact with the signal person?” Stop immediately. After preparation work, observe the use of the work basket during a cleaning, painting, or maintenance job. Reference DVD-ROM 20.0425. 62. Show how to secure equipment on the deck in preparation for rig moving or bad weather. Observe participants preparing for rig moving or bad weather operations. They should explain any restrictions that may affect the method of securing materials and equipment on deck. Ask questions such as: “How do you secure tubulars and other equipment for a rig move?” Use wire rope and wire-rope clips and turn buckles across tubulars and other items where possible. Use chains with boomers to secure odd-shaped pieces of equipment if necessary. Pad eyes may have to be welded to the deck for securing some equipment. When the task is completed, make sure that the pad eyes are removed, and the deck is ground down, primed, and painted. When using chains to secure items, shackle or hook it at both ends and use a boomer to tighten it down. The boomer is then safety wired. Use extra care when using boomers. They should be used as a last resort. Always use a cheater pipe to release the boomer and stand to the side during the release motion. For jackup rigs, ask questions such as: “Have you checked what has to be moved to lower levels before the cantilever can be skidded in or out?” “Is there anything in the way that the cantilever will hit or potentially damage during the skidding operation?” “Have you checked if anything is in the way of the electrical bridle at the port side of the cantilever that could prevent the bridle from bunching up or opening up as the cantilever is skidded?”

Rev. 02: January 2005

Crane Operator Task List Evaluation Guide 63. Show how to secure the crane for field moves and ocean tows. Ensure that participants are familiar with procedures in the operations manual that apply to cranes during field moves or ocean tows. 64. Show the procedures for passing and recovering an anchor pendant to and from an anchor-handling boat. Observe participants assisting the barge supervisor in the anchor-handling operations. They should know the vessel specific procedures for anchor handling onboard. Ask a question such as: “What is the correct procedure to pick up the primary anchor pendant and pass it to the anchor-handling boat?” Put a 1-inch by 30-foot long sling through the eye of the pendant and place both eyes on the crane block safety hook. Put a second 1-inch by 30-foot long sling through the same eye of the pendant and choke it back on itself. Allow this sling to hang down near the actual pendant. Pick up the pendant and clear it from the deck clamp or sock, then lower it down to the anchor boat’s roller so that the sling hanging down can be pulled on board with a boat hook as the pendant is lowered down about 10 feet out of the water. The boat crew should hook onto this sling with their deck tugger and pull the pendant onto the deck as the crane slacks off to keep the slings loose. The deck crew can line up the pendant to sit on top of the boat’s jaws. After the jaws are raised, the deck crew slacks off on their deck tugger so the ferrule of the pendant is held at the jaws. The crane now slacks off to allow the doubled-up sling to be removed from the crane’s safety hook. The crane can be raised out of the way while both slings are removed and then lowered to receive the two slings, or they can be picked up later. (Note that the old method of wrapping a sling around the pendant wire is no longer allowed.) The pendant is picked up in the reverse order. The deck crew should have the pendant eye in the jaws and thread one 1inch by 30-foot sling through it and place both eyes of the sling onto the safety hook on the crane hook. The second sling is choked around the eye of the pendant and connected to the boat’s deck tugger. The crane leaves the slings slack but stays directly above the pendant eye. The weight of the pendant is taken by the deck tugger and the jaws are lowered. The tugger is slacked off until the pendant eye is at the roller of the boat. Here the crane takes the weight of the pendant and holds the eye just above the roller while the boat crew removes their tugger from the second sling. When this action is done, the crane lifts the pendant up as high as needed and places it in the deck clamp to be secured. Reference CD-ROM 61.10020. 65. Describe deck area load restrictions on your rig and where to find this information. Participants should show how to reference the Operations Manual for information concerning maximum deck load for specific areas. Observe participants loading materials on deck. Ask questions such as: “Where would you store a shot of anchor chain on the rig?” On the catwalk, as it has the highest point loading of any area on the rig. “How would you handle a spool of drilling line weighing about 25 tons that is unloaded from the workboat to the rig?” Use a 3/4-inch or thicker steel plate laid directly onto the flat deck, preferably over a main support beam. The steel plate distributes the weight over a larger area. “In which direction would you run spreaders to take the weight of a heavy lift?” Spreaders are run perpendicular across beams. Know beforehand which way the angle braces and beams are running under the deck. 66. Show how to carry out routine maintenance on waste/trash disposal and environmental protection equipment. Explain trash separation and trash compactor procedures on the rig. Observe participants properly handling and operating the waste disposal equipment. They should describe onboard waste disposal and recycling programs in place. Review the Garbage Record Log with participants.
