23 OPERATIONS OPERATIONS 23

24 4. OPERATIONS WARNING: Do not touch the VES-CL Elevator, unless hydraulic power is disconnected. WARNING: Never open the elevator when the pipe load is still suspended by the elevator. WARNING: Observe the elevator continuously while closing to check if the elevator is properly closed. The CL-250 Elevator PN Y-H-T is WITHOUT closing signal, therefore extra caution needs to be taken to ensure that the elevator is properly closed BEFORE picking up any load. Safety Make sure that ALL hydraulic lines are isolated (disconnected) before any work is carried out on the VES-CL Elevator. It is recommended to have the VES-CL Elevator operated by the driller. The VES-CL Elevator is activated with a remote control valve, which may be actuated by hand or foot depending on the type of valve and/or HMI-interface. The driller (and or the floor man) must coordinate operation of the elevator and slips/spider so one tool is engaged around the tubular before the other is disengaged. Thus, one or both tools continuously suspend the tubular during all stages of pipe handling operations. Operation Running in / Tripping OPERATIONS 1. The CL-250 elevator is lowered around the tooljoint and the command close elevator is given. 2. A signal is given to the driller when the CL-250 elevator is closed NOTE: Only for elevator model Y-H-TF with closing signal) 3. The pipe is made up. 4. The driller lifts the CL-250-elevator in order to pick up the load. 5. The slips/spider is commanded to open, simultaneously, the driller picks up the elevator while the driller raises the spider/slips. 6. The driller lowers the string into the hole. 7. The driller sets the spider/slips. 8. Open the CL-250 Elevator and pick up a new section of pipe. Operation Running out / Tripping 1. The CL-250 elevator is lowered around the tooljoint and the command close elevator is given. 2. Observe the CL-250 Elevator is closed when the elevator closed indication signal is visible. NOTE: Only for elevator model Y-H-TF with closing signal 1. Raise the spider/slips. 2. Pull out the string. 3. Close the spider/slips 4. Release the stringweight from the CL-250 Elevator by lowering it slightly 5. Now running out the stand or joint. 6. When the pipe is running out, pick up the stand and set it back. 7. Open the CL-250 Elevator and guide pipe out. 8. Lower CL-250 Elevator and pick up the string at rigfloor. 24

25 MAINTENANCE & INSPECTION MAINTENANCE & INSPECTION 25

26 5. MAINTENANCE AND INSPECTION General WARNING: For service and maintenance activities, make sure that no hydraulic pressure exists on the elevator and that the connecting lines are disconnected. Lubrication The elevator needs to be lubricated regularly on the following points. Use a grease gun: Grease points: 1. On top and bottom of the latch pin (2 nipples each). 2. Lubricate springs daily. 3. Check and lubricate latch opening arrangement daily. 4. On top and bottom of the hinge pin (2 nipples each). Daily Inspection The Function of the Feedbacksignal has to be checked daily. Locking of screws All screws are normally secured by mechanical bolt lock or with a lock wire. Grease point 1 on the elevator Grease point 2+3 on the elevator MAINTENANCE & INSPECTION Grease Quality In order to achieve efficient greasing even at different environmental temperatures, we recommend the following grease types should be used (obtainable from Blohm + Voss Oil Tools): Low-Viscosity grease Type AVIATICON Grease XRF Grease point 4 on the elevator Alternatively; Use EP1 gear lubricating grease for greasing non-oil tight gear trains when temp. < 0 C/32 F. Use EP2 when temp. > 0 C/32 F. WARNING: Ensure to wear personal safety protection like gloves and safety glasses when handling hydraulic oil and/or grease. Oil and grease may be potentially harmfull for skin and eyes. Recommended grease gun 26

27 2. 1. Bushing Wear Check Wear of Equipment Normal wear of bushings and elevator ears caused by usage will eventually reduce the load capacity of elevators. The existence of cracks or the appearance of defects can indicate severe deterioration and even failures. Prompt attention is required either to remove the elevator from service immediately or to undertake appropriate repair. A wear condition in its early stages is common. Frequently, it results in a tool joint sticking to the elevator. Elevators showing hammer marks around the top of the bore should be closely examined to determine whether it is the elevator, the tool joint or both are faulty. To indentify the conditions of the 18 Elevator taper gauges are available for all B + V Elevators (P/N ). A set of gauges consists of an 18 gauge (GOOD) and a 15 gauge (BAD). How to check the bushing the correct way 1. Fit the gauge to the inner bore of the bushing. 2. Push the gauge against the bushing and start to move the gauge downwards until the chamfer touched the 18 shoulder. 3. Check the result as follows: Check of results 1. Using the GOOD gauge: If the gauge sits directly on the bushing without showing any clearance between gauge and bushing, the bushing is OK. 2. If the gauge shows space between the gauge and the bushing, you have to check with the second gauge. 3. Using the BAD 15 gauge: If the gauge shows any clearance between gauge and bushing, the bushing is OK. 4. If the gauge sits directly on the bushing without showing any space between gauge and bushing, take the elevator out of service. WARNING: If the taper is less than 15 take the elevator out of service or exchange the bushing. If the taper is between 18 and 15, reduce the elevators load capacity to 90%. Never use the elevator without a bushing. MAINTENANCE & INSPECTION Gap or no Gap? Blohm+Voss 18 and 15 gauge (P/N ) 27

28 Minimum ear dimensions WARNING: Minimum ear dimensions are only valid when the elevator is in otherwise good condition, does not have excessive wear, cracks or other defects, or previous weld repair and has not been misused. This inspection criteria can not on their own determine the overall condition of the elevator and its suitability for continued use.

30 Maintaining the Closing Signal Valve (Elevator model Y-H-TF only) MAINTENANCE & INSPECTION Inspection and Maintenance An inspection is recommended at least on a daily basis (Cat II). Depending on operational factors (operating time, load cycles, environment etc.) inspection frequency can be increased. 1. Ensure the elevator is pressureless and the hydraulic lines are isolated 2. Prior to inspection, all foreign material such as dirt, paint, grease, oil, scale etc. shall be removed from the valve by a suitable method. 3. The equipment shall be inspected by a qualified person 4. Check for visible damage at the valve, its single parts and fixations screws 5. Check for loose items 6. Check the fixation screws which keeps the valve in the correct position. The screws needs to be thight and the securing elements (wire, lock washers, tab washers etc) need to be free of damage 7. Check if the red actuation roller at the valve can be moved easily by hand up and down. 8. Connect the elevator hydrauliccally. Check the open / close function of the elevator 9. Before the elevator is placed into storage, the valve must be cleaned and inspected. 10. If any malfunction occurs or anyparts were found showing cracks, excessive wear, loose or damaged items the elevator shall be removed ffrom service for further examination. Function of Valve When the elevator is fully closed and latched, the valve is actuated. Therefore hydraulic pressure passes through and pressurizes line C (Elevator closed signal). The signal indicates the operator that the elevator is properly closed and latched. Location of Valve The hydraulic valve (p/n ) is located at the Latch Lock in front of the elevator. The exact position varies slightly depending on the elevator type (see pictures for example). GREASE DAILY Warning Position of valve 30

31 Inspection categories acc. to API RP 8B Category I This category involves observing the equipment during operation for indications of inadequate performance. When in use, equipment shall be visually inspected on a daily basis for cracks, loose fits or connections, elongation of part, and other signs of wear, corrosion or overloading.

37 7 26 Adjustment procedure Feedback Valve (Closing Signal) In case the elevator does not give a proper closing signal, the feedback valve may be in need of readjustment. To check if this is the case, close the elevator. When the elevator is fully closed, move down the valve roller manually. If a closing signal occurs, the valve has to be readjusted. If no closing signal occurs, it is possible the valve is damaged or defect and has to be replaced. Procedure to readjust the valve : unscrew the screws at position 28 and disassemble the protection cover loosen the screws at position 35 slightly move the valve slightly upward by turning the adjustment screw at position 31 Warning: be carefull moving the valve upward, only a small distance may be necessary. If the valve is placed too high, it can be crushed when closing the elevator tighten the screws at position 35 check the closing signal by closing the elevator if there is still no signal, move the valve a bit higher and check again, repeat till the closing signal works After successful adjustment, make sure all screws are tightened and all safety elements are in place.
