I. RISER

A. Description

The marine riser forms a continuation of the well bore from the top of the blowout preventer stack to the drilling vessel. Risers differ in the auxiliary line size, length and wall thickness of the pipe and, if used, buoyancy material. The LK 3.5 risers are rated to 3,500,000 pounds (15,569 Kilonewtons) and have integral auxiliary lines. All Choke, Kill, and Mud Boost Auxiliary lines are NACE certified for H2S Service (applies to pup joints as well). See the riser assembly drawing in this section for detailed specifications.

Note: The seal sub for the LK riser may be run in either flange, but for clarification, for the re-mainder of this text, the flange with the seal sub will be referred to as the PIN, and the flange without the seal sub will be called the BOX.

B. Operation

The rig operator must establish the limits for riser operation based on the characteristics of the drilling vessel, riser system, and expected environmental conditions. This will mini-mize riser damage from overstress and/or fatigue. Also, the rig operator must establish the tensioning program for the riser system. Always maintaining the correct amount of tension at the top of the riser prevents column buckling, and minimizes bending stresses and flex joint deflection. For additional information on the operation and maintenance of marine drilling riser, see API bulletin RP16Q.

1. Inspect the riser assembly.

Perform the following procedure while the riser is on the pipe rack or in the stor-age area.

a. Inspect the riser pipe, including auxiliary lines and, if used, the buoyancy equip-ment for external damage. Repair if necessary.

b. Ensure that the auxiliary lines are securely clamped to the riser pipe. See the LK Riser Joint Assembly Descriptions and Dimensions Table (or illustration) for rec-ommended number and location of clamps for bare joints and joints with buoy-ancy modules. When installing the clamp assemblies, torque the bolts to 51 ft-lb (69 Nm) using a molylube.

c. Inspect the connector for external damage. Repair if necessary. See the Riser Connectors section of this manual for inspection procedures.

d. Remove the pin protectors from the riser and auxiliary lines.

e. Inspect the bores of the riser and auxiliary lines for obstructions and wear.

f. Clean the pins of the auxiliary lines and the seal sub with fresh water.

16TC9162

Important: DO NOT use salt water.

g. Inspect the sealing area on the pins for excessive wear or damage. Repair if nec-essary. See the Riser Connectors section of this manual.

h. Apply a thin coat of clean, water-resistant mineral grease to the seal sub and auxiliary line pins.

Important: DO NOT use a metallic-compound grease, such as thread dope.

i. Install the pin protectors.

Caution: DO NOT remove the pin protectors until the riser joint is on the rig floor.

j. Remove box protectors.

k. Clean the riser boxes and auxiliary line boxes with fresh water.


l. Inspect the seals for excessive wear or cuts. Replace if necessary.

m. Apply a thin coat of clean, water-resistant mineral grease to the riser boxes and auxiliary line boxes.

n. Inspect the bolts and nuts for excessive wear or damage. Replace or repair if nec-essary. Clean thoroughly and protect against corrosion.

o. The nuts are retained against rotation by a dowel pin. The anti-rotation pin and nut are retained in the flange by a roll pin. When properly installed, the end of the roll pin will be flush with the outside diameter of the flange.

2. Move the riser joints into position for installation according to rig procedure using the following guidelines:

a. Always handle the riser joints with the pin protector installed.

b. If automatic handling equipment is not available, use a guideline and a sling specially designed for picking up and moving riser joints with a crane.

c. Do not pick up riser joints by the auxiliary lines or brackets. Use the lifting eyes located on both the pin and box ends of the riser joints for the sling.

d. Move the riser joints slowly and carefully out of the pipe rack. This prevents damage to the equipment and/or risk of injury to personnel.

Note: Foam buoyancy material on risers is easily damaged.

3. Install the riser.

a. Secure the riser spider to the rotary table according to the manufacturers in-structions and rig procedures.

b. Ensure proper spider operation according to rig procedures before installing the first joint of riser.

c. Use the riser handling tool, and install the first joint of riser pipe.

d. Ensure cleanliness of threads on both the bolts and nuts, then lubricate threads, bolt collars, and under the bolt head with Hydratight/Sweeney 503 Moly Paste Lubricant or Loctite Moly Paste C-670.

e. Align the riser box end to correctly fit the riser pin end.

17TC9162

Note: If there are more than two auxiliary lines, ensure proper orientation of the lines as the riser joints are stabbed together.

f. Ensure that the connector bolts are fully retracted into the flange.

g. Lower the riser into position, ensuring that the mating flange faces are in full contact.

h. Tighten the riser bolts, using one of the two options described in steps 4 and 5.

4. Bolt installation using one hydraulic torque wrench.

a. Ensure that the nut and bolt threads, the bolt collars, and the nut bearing faces are clean and lubricated with Hydratight/Sweeney 503 Moly Paste Lubricant or Loctite Moly Paste C-670.

b. Hand-tighten all the bolts into the nuts.

c. Apply 9000 ft-lb (12,202 Nm) of torque to one of the bolts. Verify the applied torque using the gauge on the power supply.

Note: Refer to the calibration certificate provided by torque tool manufacturer.

d. Move the wrench to the bolt 180O away from the first bolt. Apply 9000 ft-lb (12,202 Nm) of torque to the bolt.

e. Move the wrench back to the first bolt. Apply 18,000 ft-lb (24,405 Nm) of torque to the first bolt.

f. Move the wrench to the second bolt and apply 18,000 ft-lb (24,405 Nm) of torque.

g. Continue to torque the bolts to 18,000 ft-lb (24,405 Nm) according to the se-quence illustrated in the diagram below.

Bolt Torque Sequence5. Bolt installation using two hydraulic torque wrenches.

a. Ensure that the nut and bolt threads, the bolt collars, and the nut bearing faces are clean and lubricated with Hydratight/Sweeney 503 Moly Paste Lubricant or Loctite Moly Paste C-670.

b. Apply 18,000 ft-lb torque (24,405 Nm) simultaneously to two bolts 180O apart, using the two hydraulic torque wrenches.

c. Move the hydraulic torque wrenches to the next two bolts 180O apart, and apply 18,000 ft-lb torque (24,405 Nm).

18TC9162

Important: Either a clockwise or counterclockwise rotation may be used, but the two hydraulic torque wrenches must always be 180O apart.

d. Move the hydraulic torque wrenches to the final two bolts, and apply 18,000 ft-lb (24,405 Nm) torque.

6. Rotate the riser joints after retrieval.

When storage space permits, change the relative position of the joints in the riser string within wall thickness and buoyancy water depth rating ranges each time the riser is run.

C. Pressure Tests

1. At the installation of each third riser joint, pressure test each choke, kill, or other control line with a suitable fluid to the full working pressure of the line.

2. Hold the pressure for at least three minutes, or follow the rig procedures for pres-sure testing of the lines.

3. If a pressure loss is evident, inspect the seals. Replace if necessary.

Note: Pressure test all appropriate lines on the riser to working pressure of the line prior to starting well operation.

D. Field Inspection and Maintenance

1. Visually inspect the riser.

After use in extreme conditions, or six months of normal drilling conditions, inspect each riser joint for corrosion, cracks, or excess wear. Repair if necessary.

2. Inspect the coated surface of the riser.

All external parts of a riser joint, except moving parts and mating surfaces, are coated with three part epoxy.

a. Inspect the coated surfaces for cracked or flaking coating.

b. If cracked or flaking coating is found, thoroughly clean the area of rust or grease, and recoat.

c. Clean the pins and boxes with fresh water.


d. Replace the seals, if damaged, using the seal insertion tool, P/N 698908-01.

e. Grease the pins and boxes with a light coat of clean, water-resistant mineral grease.

Important: DO NOT use a metallic-compound grease, such as thread dope.

E. Storage

1. Ensure that proper maintenance is performed before storing riser joints. See the Riser Description and Operation sections of this procedure. See the Riser Connectors section of this manual.

19TC9162

2. Store riser joints on riser storage racks or on cradles designed specifically for sup-porting the weight of the riser.

3. Arrange the racks to facilitate a riser joint rotation system. See operation section of this procedure for joint rotation guidelines.

4. Do not support riser joints by the buoyant sections or auxiliary lines.

5. Always store riser joints with the pin protectors in place.

6. Do not block access to the pin protectors. Access must be maintained for periodic inspections and maintenance while in storage.

7. Place wooden strips and supports, at least 18 (457 mm) from the ground, under the bottom layer of riser joints and also between riser joint layers. Use an adequate number of strips and supports to prevent the riser joints from bending.

8. Stack the riser joints in a slightly inclined position to ensure proper drainage of col-lected water.

F. Transportation

1. When loading riser joints on freight cars, supply boats, or any other transport ve-hicle, cover the bottom of the vehicle with wooden planks.

2. If the bottom of the vehicle is uneven, rigidly shim the planks so that the tops of the planks are level.

3. Tie down and properly secure the riser joints to keep the load from shifting.

4. Protect painted or coated surfaces from the tie-down clamps or straps with heavy duty rubber pads or the equivalent.

5. Do not stack drill pipe, drill collars, casing, or other miscellaneous cargo on or be-tween the riser joints.

II. RISER CONNECTORS

A. Inspection and Rework

Use the following procedure after one complete drilling operation in extreme conditions, after six months of normal drilling, before storage, or if a connector has been damaged.

1. Inspect the riser box connector and repair if necessary.

a. Remove LK bolts and inspect for thread damage, galling on the bottom of the bolt head, or damage to hex flats of bolt head. Replace if necessary. Refer to EB695D for further thread inspection information.

b. Remove the six roll pins, P/N 2090495-01, by driving them into the bore of the nuts. Remove the nuts and anti-rotation pins, P/N 2724226-01. Inspect the nuts for thread damage and galling to the top and bottom faces of the nuts. Replace if necessary.

c. Clean the inside of the box thoroughly with fresh water.


d. Inspect inside the LK riser connector for damage to the sealing area and the run-ning tool lock-ring groove area. Remove any small burrs using #150 emery cloth.

20TC9162

e. Perform a surface Non-Destructive Examination (NDE) inspection of the riser connectors in the areas shown. This inspection should also be performed on the inside diameter of all splice welds. Wet fluorescent magnetic particle inspection is recommended.

f. Grind out any suspect cracks to determine the depth of the crack.

1.) If a crack greater than .030 (0.76 mm) in depth is found, the crack must be repaired using Cameron welding specifications or the complete connector box must be replaced. Contact a Cameron representative if field repairs are needed. Do not weld riser joints in the field.

2.) If a crack less than .030 (0.76 mm) in depth is found, the crack does not need to be weld-repaired. Blend the ground-out area into the original surface.

g. Apply a light coat of water-resistant mineral grease to all internal surfaces and components.

2. Inspect the riser pin connector and repair if necessary.

a. Clean the pin thoroughly with fresh water.


b. Remove the seal sub retainer, P/N 648749-02, by using a screwdriver in one of the four slots in the flange to hold one side, and another screwdriver in the slot 180O apart to pry out one end of the split retainer wire.

c. Inspect the seal sub for any signs of damage. Remove any burrs near the seal groove area using #150 emery cloth.

d. Follow the same instructions as given in the previous section pertaining to in-spection of the riser box connector.

e. Apply a thin layer of water-resistant mineral grease to the seal and the grooves.

f. Install new seals on the seal sub.

g. Re-install the seal sub into the LK flange.

h. Re-install the seal sub retainer wire.

i. Coat the pin with water-resistant mineral grease.

3. Inspect the auxiliary line connections and repair if necessary. Each auxiliary line should be inspected according to the following procedure:

TENSION RING OPERATION PROCEDURE

I. PURPOSE

The purpose of this procedure is to provide pre-commissioning RUNNING and RETRIEVAL IN-STRUCTIONS LK-35 RST RING ASSEMBLY NO. 2329218-01

II. PRE-COMMISSIONING MAINTENANCE AND FUNCTION TESTING

1. Load dogs, centralization dogs and the internal locking ring must be greased, and then function and pressure tested to 3000 psi on the deck. The hydraulic source must come from the DCU Control Bundle. This pre-commissioning verification must be done prior to deployment. Initial verification testing is essential to provide con-firmation of smooth operation and serve as a proof test that the PLC Logic sequen-tially operates as intended. In particular, it confirms the functional PLC lock-outs are working correctly.

2. There are six top grease ports and 12 peripheral grease ports shown in Fig. 1 and Fig. 2. A pneumatic grease gun has been provided to speed the lubrication process. All ports are 1/8 NPT. Use x 1/8 NPT standard grease fitting.

Fig.1 - 6 Top Grease Ports Fig. 2 - 12 Peripheral Grease Ports

3. All dog cavity wipers are to be fitted prior to commissioning deployment as a safety measure that is intended to prevent seawater corrosion in the dog cavities.

4. Verification of actuation ring positioning Indicators is also required to ensure that the internal traverse of the back-up lock ring is correct when in the extend and retract position. The position indicators can be observed from the DCU room level. The extended and retract positions are shown in Fig. 3 and Fig. 4.

58TC9162

Fig. 3 CCW => Ring Extended (Locked) Fig. 4 CW => Ring Retracted (Open)

III. ROUTINE OPERATIONAL MAINTENANCE

The RST Dogs and Lock Ring must be exercised prior to each deployment. Function Pressure testing to 3000 psi is also required to ensure that all hydraulic lines have zero leakage. It is recommended that prior to normal periodic deployment the Dogs and Lock Ring are greased and exercised to ensure smooth operation. Marine grade grease is recommended to lubricate the components exposed to the salt water spray environment in the moonpool and thus all moving parts remain lubricated and protected. This is particularly important for the 6 load dogs and the 6 centralization dogs, as well as the locking ring lower track and gear segments. The dogs are directly lubricated through 12 grease ports located around the periphery of the lower ring covers, and 6 grease ports on the top flange of the inner body. These ports are di-rect lines to the bottom and top of the load, and centralization dog cavities. The dog faces in the RST ring bore are equipped with UHMWP and soft Neoprene wipers that resist water and foreign material from entering the dog cavities of the machine in the RST load body. RST Ring must be lowered to the LMRP trolley between deployments for cleaning, inspection, lubrica-tion, and function testing.

IV. THE FOUR FUNCTIONS OF THE RST RING

Diverter dogs extend/retract

Load dogs extend/retract

Centralization dogs extend/retract

Dog lock ring extend/retract

A. Mobilization Sequence and Interlocks

The diverter latch and un-latch is interlocked with the three other functions.

B. Deployment Sequence

1. After space-out centralization dogs extended (dogs are out)

2. Load dogs extended (dogs are out)

59TC9162

3. Back-up ring shifts to extend position (dogs are out and now backed up)

4. Diverter dogs retracted (releasing the ring, interlocked)

C. Demobilization Sequence and Interlocks

1. Diverter dogs extended (hanging the ring, interlock)

2. Back-up ring shifts to open position (dogs are free to traverse back)

3. Load dogs retract

4. Centralization dogs retract

Seq. No. Derrick Mobilize Condition

Sequence

1 After centering the TJ prep 6-8 inches Centralization Dogs Extend

2 Pull up against centralization dogs Load Dogs Extend

3 Extend the back-up ring Back-Up Ring Extend

4 Apply overpull then retract the diverter dogs Diverter Lock Dogs Retrack (unlock)

Seq. No. Derrick Demobilize Condition

Sequence

1 Apply overpull against the centralization dogs Diverter Lock Dogs Extend (lock)

2 Slack off 6-8 inches (hangs the ring) Back-Up Ring Retract

3 Retracts load dogs with zero load Load Dogs Retract

4 Retracts centralization dogs with zero load Centralization Dogs Retract

Warning: Do not alter the ladder logic in any manner. Lockouts and exclusions are pro-grammed in to prevent incorrect function sequencing. In particular the ladder logic prevents operation of the 4th function (the back-up ring) with either or both sets of dogs in the retracted position. The reason for this is the dog operation cylinders are protected from the ring cams that can force the dogs to extend against a closed hy-draulic piston. The only way the ring can operate is if both sets of dogs are extend-ed. This eliminates the forgoing possibility of incorrect loading on the dog cylinders. Also the logic prevents retraction of the dogs against a locked backup ring. This is excluded to avoid unnecessary loading of the backup ring. The ring is designed to mechanically maintain the position of the dogs regardless if hydraulic pressure is present or not.

Caution: During mobilization or demobilization do not operate the Centralization Dogs or Load Dogs when any axial load is applied. Always lift the load off the dogs before retraction per the below instructions. The dogs are operated by independent hydrau-lic cylinders. At 1500 psi these cylinders have a pushing force outward of 4000 lbf and a pulling force of 2000 lbf. The forces are doubled at maximum emergency opera-tion pressure of 3000 psi. Any load on the dogs should be reduced to zero before any retraction (or extension) functions are conducted. See Figures 5 and 6.

60TC9162

V. RUNNING THE TELESCOPING JOINT WITH THE RST RING

The above elevations shown in Fig. 5 indicate the distance from the drill floor level to the bottom face of the diverter housing. This distance is 141.7 (12.64) and provided as a reference. This dimension should be measured and recorded.

A. General Running Sequence

1. Ensure that the diverter latch dogs are closed and locked completely in the diverter housing latch groove. Maintain 1500 psi closing pressure. The diverter control panel should indicate that the RST is locked to the diverter.

2. Ensure that the load dogs, centralization dogs and the dog locking ring of RST ring are in fully open (retracted) position.

Caution: Do not attempt to run anything through the RST ring without visually checking the position of the dogs and the locking ring. This can result in damage to the RST ring.

3. Ensure that the telescoping joint auto lock is locked in safe mode (dogs engaged and locked by the actuation ring). The position indicator rod should be in the lower most position as seen from the top face of the lock housing. See operation instruc-tions for telescoping joint auto lock system.

4. Ensuring that the desired orientation is correct in accordance with rig manual in-structions, pick up telescoping joint with the riser running tool.

5. Make up the TJ outer barrel to the LK35 riser flange hanging on the spider/gimbal. Following LK35 running instructions.

6. Pick up hanging load in the derrick and record the running hook load weight.

7. Run Telescoping Joint through the rotary to the designated elevation. See Illus-tration Fig. 5 (measurements must be taken to ensure the vertical distance of the centralization dogs to the drill floor so the TJ can be marked).

8. With the RST ring latched to the diverter housing, run the TJ to the predetermined elevation where the centralization dogs can be extended without obstruction be-tween the locking faces of the riser lock section. The opening between these faces is 12.75. This running start position of the centralization dogs should be at approx-imately 6 to 8 inches above the lower face (see illustration).

9. Record again the static hook load reading. The values should be the same.

10. Extend the centralization dogs and maintain 1500 psi.

11. Lift TJ until it reaches an elevation where the hook load indicator starts showing a load increase. This weight-increase value should not exceed 50,000 lbf. This then is the indication that the centralization dogs are tagged off on the lower face of the lower riser locking face.

12. Without changing position of the running string extend the load dogs and main-tain 1500 psi.

13. Extend the back-up ring and ensure that it is in the extreme locked position. Check this visually from below. The three position indicators are located under the bottom face of the RST rings and are spaced at 120 apart. These indicators are attached to the lower shaft portion of the linear actuators and directly reflect the position of the Lock Ring. See Fig. 3 and Fig. 4.

14. Lift the load in order to conduct a 50,000 lbf over pull to ensure that the load dogs are engaged.

15. Slack off on the derrick to the previously recorded hanging load to relieve the load on the diverter dog load. Open the diverter locking dogs to release the RST ring from the diverter housing. The lifting force may require further reduction to free the diverter locking dogs.

16. In accordance with the rig operations procedure manual, under control of the derrick, lower the TJ/RST Ring to tensioner engagement position to facilitate the marine riser tension on the RST ring. It is recommended that the tensioners are engaged slowly to facilitate a smooth and uniform load transition from the derrick.

VI. GENERAL DEMOBILIZATION AND RETRIEVAL SEQUENCE

Note: The diverter latch and unlatch (open/close) is interlocked with the other functions. The sequence must be the following:

1. Check the controls to ensure that the locking ring, centralization and load dogs have remained in the fully locked position.

2. Ensure that the diverter locking dogs are in the fully retracted (open) position and ready to hang the RST ring.

3. In accordance with rig operations manual, under the control of the derrick slack off the tensioners then elevate the RST ring to the engagement position with the

62TC9162

diverter housing. At this stage the entire load of the RST ring and wire ropes will be resting on the centralization dogs.

4. Lock the diverter latch dogs and maintain a minimum of 1500 psig closing pressure.

5. In the following sequence disengage the RST ring from the TJ.

6. Retract the lock ring. Check the position indicators to ensure that the ring is in the fully open position. Maintain 1500 psig.

7. Lift any load off the main load dogs then retract the main load dogs to the fully open position and verify on the control. Maintain 1500 psig.

8. Lift the TJ to the initial running engagement position removing any load from the centralization dogs.

9. Retract the centralization dogs and maintain 1500 psig.

10. Pull the TJ through the rotary and demobilize per rig operations manual.

Fig. 6

Shown above in Fig. 6 is the cross section of the RST ring locked to the telescoping joint and the diverter housing prior to deployment or upon retrieval. The reaction ring is shown (blue) permanently locked to the TJ load shoulder preparation. During the first TJ deployment is essential and safe to mount this reaction ring to the TJ on the drill floor when the TJ is in the vertical position. The ring is split and has studded faces. It is impor-tant to include the neoprene shock pad so the ring will compress the TJ body and be able to tolerate shock loads when the tag-off during deployment (discussed above) is encoun-tered, also when the MRTs engage the RST rings.

VII. MISCELLANEOUS NOMENCLATURE

Fig. 7

Fig. 7 shows the assembly with the bottom funnel and dog housing removed. The back-up ring is shown in the extended (locked) position with the dogs extended. The back-up ring is rotated using three linear actuators positioned at 120. The actuators are connected to a continuous hydraulic source and operate in together to turn the ring. The bulkhead connections are shown in the forefront. There are eight ports for four functions that ex-tend/retract the dogs, ring and diverter lock dogs.

TELESCOPING JOINT AUTOLOCK MECHANISM

I. DESCRIPTION

The outer barrel of the telescoping joint may be prevented from stroking relative to the inner barrel by engaging the telescoping joint locking mechanism. The lock is controlled by an ac-tuation ring (item 14) that is driven by two hydraulic cylinders (item 16) set at 180O apart. Load dogs (item 15) are used to transfer load from the outer barrel to the lock body. The actuation ring controls the position of the load dogs. Two position indicators (item 2) extend above and below the outer lock body (item 1). Not only do the position indicators provide a visual sign as to which mode the actuation ring is in, they provide stability for the cylinders driving the actuation ring.

SD-017666Unlocked Mode

SD-017667Autolock Mode

Secured ModeSD-017662

The telescoping joint lock has three modes of operation: unlocked, automatic lock and se-cured lock. All three modes are dictated by the position of the actuation ring. When the ring is in the unlocked mode (highest position) the load dogs are fully retracted allowing the telescoping joint to stroke freely. In the automatic lock mode (center position) the load dog extend through the actuation ring windows but have full freedom of movement through their swing arc. This allows the telescoping joint load dogs to engage the lock body flange (item 17 on the Dual Seal Subassembly drawing) when the inner barrel is fully stroked into the outer barrel. The secured lock mode is used after the lock body flange has been engaged by the load dogs and all overstroke has been removed. This moves the upper window lip of the actuation ring behind the load dogs preventing the load dogs from rotating in their arc.

SD-017670Flange in Overstroke Position

SD-017671Flange in Full Seated Position

Warning: The lock should only be operated while telescoping joint is in the vertical position.

72TC9162

II. UNLOCKING THE TELESCOPING JOINT

a. Ensure the tensioners are secured to the tension ring and that the tension ring is secured to the telescoping joint.

b. Place the telescoping joint lock in the automatic lock mode. Verify placement by visually inspecting the position indicators (item 2).

SD-017664Autolock Mode

Note: The position indicator has three grooves. Two grooves are on top of the rods and one on the bottom. One groove should be in close approximation to a bearing cover (item 4) during each mode. The distance from groove to plate might vary slightly from lock to lock but remain constant from cycle to cycle on an individual lock.

c. Either raise the outer barrel or lower the inner barrel approximately 4. This will place the telescoping lock in the overstroke position.


d. Move the telescoping joint lock to the unlock mode. Verify placement by visually inspecting the position indicators (item 2).

SD-017663Unlocked Mode

e. Separate the inner and outer barrel on the telescoping joint.

Warning: Never attempt to place lock body flange in the overstroke position while the tele-scoping joint lock is in the secured lock mode!


TC9162 73

III. LOCKING THE TELESCOPING JOINT

a. Move the telescoping joint lock to the automatic lock mode. Verify placement by visually inspecting the position indicators (item 2).

b. Close the telescoping joint inner barrel into the outer barrel until fully retracted. This will put the telescoping joint into the overstroke position while engaging the load dogs (item 15) with the lock body flange (item 17 on the Dual Seal Sub-assembly drawing).

c. Extend the telescoping joint inner barrel out from the outer barrel until the load dogs fully seat against the lock body flange. This is approximately 4.

Note: When fully seated the telescoping joint lock will carry the loads applied through the outer barrel.


d. Move the telescoping joint lock to the secured lock mode. Verify placement by visually inspecting the position indicators (item 2).

SD-017665Secured Mode

Note: During normal operating conditions, the telescoping joint lock may either remain in the automatic lock mode or the unlock mode. If placed in automatic lock mode the telescoping joint lock will engage if fully retracted. This will be prevented by operating telescoping joint in the unlock mode.

TELESCOPING JOINT WITH HYDRAULIC LOCK MECHANISM

I. SUMMARY

The telescoping joint compensates for changes in the distance between the drill ship and the BOP stack. Waves, tides, or ship movement cause a change in distance between the ship and BOP stack. The telescoping joint extends and retracts to compensate for this change in dis-tance.

The telescoping joint consists of two, sliding, concentric pipes, which are referred to as the in-ner and outer barrels. The construction of the telescoping joint allows the inner barrel to slide up and down the inside of the outer barrel without leaking. The larger, outer barrel, located at the bottom of the telescoping joint, is attached to the top of the last riser joint with a riser connector. The smaller, inner barrel, located at the upper end of the telescoping joint, is at-tached to the hydraulic lock mechanism, which has a riser connector on top.

An elastomer sealing element seals the annulus between the inner and outer barrels. The pressure rating of the elements is 500 psi (34.5 bars). Air or hydraulic pressure approximately 10% greater than the bore pressure is required to seal the space between the inner barrel and the outer barrel, depending upon the condition of the elements and inner barrel. The seals and the wear bushings also keep the inner barrel aligned inside the outer barrel. A seawater hose connected to the locking flange wets the dry space above the upper split seal.

II. INSTALLATION

Note: Refer to the Upper Housing/Double Seal Subassembly illustration and parts list for item identification.

Install the telescoping joint on the riser string as follows:

1. Suspend the last riser joint in the spider.

2. Ensure that the telescoping joint lock is in the locked position. Refer to the Au-tolock section of this manual.

3. Pick up the telescoping joint, and install it on the riser string.

4. Make up the lower flange on the telescoping joint per procedures shown in the riser section of this manual.

Note: If the weight is to be supported on the shoe ensure that the shoe has not worn below the wear indicator groove on the outside diameter of the shoe. Refer to the Inner Bar-rel section of this manual for shoe inspection procedures.

79TC9162

Lower the telescoping joint and the BOP stack as follows:

1. Support the telescoping joint with the draw-works.

2. Retract the spider dogs.

3. Lower the telescoping joint.

Note: At this time the energizing pressure function of either split seal may be pressure tested. Both split packers may also be pressure tested simultaneously by applying pressure through the port in the double flange between the seal housings.

If pressure testing is not performed at this time proceed to step 6.

4. Extend the spider dogs under the lower seal housing, suspending the telescoping joint in the spider.

Note: The telescoping joint can be suspended from the bottom of the lower seal housing or the riser flange on top of the telescoping joint. In either case the spider dogs should be fully extended and the mechanical stops installed.

5. Pressure test the double seal subassembly for leaks as follows:

Energizing Pressure Test

a. Connect the air or hydraulic line in place of either pipe plug (item 3 of Double Seal Assembly Parts List) in both seal housings (item 4 of Double Seal Assembly Parts List).

b. Apply energizing pressure, per rig operational requirements, to seal against 500 psi (34.5 bars) maximum bore pressure.

c. Check for leaks, and watch for pressure drop.

d. If the pressure does not hold, release the remaining pressure, and repair the leak. Refer to the Seal Assembly section for seal replacement procedures.

e. Relieve energizing pressure.

Bore Pressure Test

To test the packers, bore pressure may be applied between the upper and lower seal housings. Depending on the condition of the packers and inner barrel, the required ener-gizing pressure is approximately 10% higher than bore pressure.

a. Remove the pipe plug from the double flange (item 6 of Double Seal Assembly Parts List) and connect a test line.

b. With seal energizing pressure applied, apply bore pressure to test port in the double flange (item 6 of Double Seal Assembly Parts List).

c. Check for leaks, and watch for pressure drop.

d. If the pressure does not hold, release the remaining pressure, and repair the leak. Refer to the Seal Assembly section for seal replacement procedures.

e. Relieve all pressure.

6. Attach the tension ring to the telescoping joint per procedures in the tension ring section of this manual.

80TC9162

7. Attach choke, kill and auxiliary goosenecks per rig operating procedures and the following:

a. Lift the gooseneck into position using the lugs provided.

b. Lower the gooseneck slowly. Check for a proper stab of the gooseneck pin into the auxiliary line box.

c. Stab the gooseneck pin into the auxiliary line box.

d. Turn the threaded hammer nut down to fully engage the threads. Torque ap-plication to preload is not required.

8. Attach seal energizing lines to the seal housings.

9. Attach operating pressure lines to the Autolock.

10. When the lock body flange has cleared the locking mechanism, inspect the lubrica-tion port for mud, grease, and other foreign matter.

11. Remove any mud, grease, or other foreign matter from the lubrication port.

12. Ensure that the port which supplies lubricant to the inner barrel is open.

13. Attach seal lubrication lines to the lock body flange (item 17 of Double Seal Assem-bly Parts List).

14. Lower the BOP stack onto the wellhead.

III. RETRIEVAL

The following procedure details the steps necessary to retrieve the telescoping joint.

1. Disconnect the BOP stack from the wellhead.

2. Raise the telescoping joint outer barrel.

3. Place the telescoping joint lock in the locked position.

4. Disconnect the seal lubrication lines from the lock body flange.

5. Disconnect the operating pressure lines from the Auto lock.

6. Disconnect the seal energizing lines from the seal housings.

7. Remove the choke, kill, and auxiliary line goosenecks per rig operating procedures and the following

a. Attach lifting device to lifting lug on the gooseneck. Take the slack out of the line. DO NOT OVERPULL THE GOOSENECK!

b. Unscrew the hammer nut.

c. Pull up on the gooseneck keeping the connection pin vertical.

8. Disconnect the tension ring from the telescoping joint per procedures in the ten-sion ring section of this manual.

9. Raise the telescoping joint and the riser string until the bottom flange on the tele-scoping joint and the top flange on the uppermost riser joint are above the spider dogs.

10. Extend the spider dogs.

11. Break out the lower flange bolts on the telescoping joint per the procedures found in the riser section of this manual.

12. Lift the telescoping joint off of the riser string and place it in its storage position per rig procedures.

81TC9162

IV. OPERATION

Refer to the Autolock Subassembly illustration for item numbers.

A. Autolock Description

The Autolock provides a means for preventing the outer barrel of the telescoping joint from stroking relative to the inner barrel. Locking the telescoping joint barrels is neces-sary during transportation and storage. Also it may be required when landing the stack on the wellhead during operation. The three positions of the Autolock are unlocked mode, autolock mode, and secured mode. When the outer barrel is locked in the au-tolock or secured modes, the lock has a rating of 2.4 million pounds.

The locks mode is dictated by the position of the actuation ring (item 14). The actua-tion ring has three positions manipulated by two hydraulic cylinders (item 16) set at 180O apart. The actuation ring controls the position of eight load dogs (item 15). The load dogs are used to transfer load from the outer barrel to the lock body. The actuation ring is connected to two position indicators (item 2) extending above and below the outer lock body (item 1). The position indicators provide a visual sign as to the current mode of the Autolock.

When the lock is in the unlocked mode, the load dogs are fully withdrawn allowing the telescoping joint to stroke freely. In the Autolock mode, the load dogs engage the lock body flange (item 17 of Double Seal Assembly Parts List) located above the packer assem-bly when the inner barrel is fully stroked into the outer barrel. The secured mode is used after the lock body flange has been engaged by the load dogs. This mode prevents the load dogs from disengaging the lock body flange. The Autolock should be maintained in the secured mode while the telescoping joint is separated from the riser string.

The hydraulic cylinders have two stages. Their combinations of extend and retract will place the Autolock in the desired mode. The lock is supplied with hoses running from each cylinder to a hydraulic block. At the block, quick connects (telescoping joint side and rig side) are supplied prepped with NPT male to receive rig hydraulic supply. The
