Installation and testing of 9.5/8" or 10.3/4" emergency seal assembly

1.0 Prepare seal assembly. Inspect for damage, paying particular attention to the 'LS'and 'T' seals. Replace as necessary. Ensure spring loaded anti-rotational pinsdepress and retract.

2.0 Make up the running tool onto NC50 handling joint.

Note: A minimum weight of 10,000 lbf is required to install the seal assembly.This may require the use of heavy weight drill collars hung from the

NC50 box thread below the running tool to supplement total hangoffweight.

3.0 Partially screw seal assembly left hand onto running tool until tool contactstapered portion of split lockdown ring. Approximately 4 turns are required tocontact split lockdown ring. Note number of turns.

4.0 Adjust bolt on the installation tool to compress the split lockdown ring.

5.0 As ring is compressed, screw the seal assembly further onto the running tool.

6.0 Repeat 4.0 and 5.0 until O/D of split lockdown ring is flush with or just below theO.D. of the seal assembly body. Approximately 4 further turns are required tofully compress the split lockdown ring. Note number of turns.

7.0 With the running tool fully engaged on split lockdown ring, adjust bolt on theinstallation tool and remove tool.

Note: After removal of the installation tool, split lockdown ring must be flushwith or just below the O/D of the seal assembly. If required, replaceinstallation tool and repeat from 4.0.

8.0 Clean seal assembly and lubricate all seals with valve grease.

9.0 Open lower outlets in the compact housing.

10.0 Slowly lower seal assembly through BOP stack and riser into housing.

Note: An increase in resistance will be felt as the I/D seals engage onto the casing.

11.0 Compare stick up above rotary table with that calculated to ensure at correctdepth. This can be verified by viewing through lower outlets.

Installation and testing of 9.5/8" or 10.3/4"emergency seal assembly(continued)

12.0 Mark angular datum on handling joint and back out running tool 4 turns righthand to allow split lockdown ring to expand into its groove in the housing.

Note 1: Initial rotation right hand of the 9.5/8" seal assembly will locate the two anti-rotation spring loaded pins of the seal assembly into the slip bowl. This will be achieved within 180°. A revised angular datum should then be marked at this point.

Note 2: Initial rotation right hand of the 10.3/4" seal assembly will locate the three anti-rotation spring loaded pins of the seal assembly into the slip

bowl. This will be achieved within 120°. A revised angular datum should then be marked at this point.

Note 3: If confirmation of ring expansion is required, an overpull of 20,000lbf can be applied to the running tool at this stage.

13.0 Ensure lower outlets are open on housing, do not retrieve running tool at thisstage.

Pressure testing of seal assembly

Note: The split lockdown ring must be expanded into the lockdown groove before pressure testing commences. Failure to do this can result in damage to the seal assembly.

14.0 Remove autoclave plug and gland from test port 1 (see page 100) in housing.

15.0 Connect pressure test pump into the test port and apply pressure while bleedingair from the opposite port. Test pressure is to be 80% of collapse of casing. Lockin for required hold period.

16.0 After successful test, release pressure, and re-install plug and gland (see Section3.6).

17.0 Fully back out running tool by right hand rotation, approximately 4 further turns(see 3.0) and retrieve. Lift slowly to ensure that the tool has fully disengaged.

Retrieval of seal assembly

Note: In the unlikely event that a successful pressure test is not obtained on the seal assembly, it may be necessary to retrieve the seal assembly andinvestigate the problem.

1.0 If the running tool is still engaged on the seal assembly down hole, proceed to 5.0.

2.0 Make up running tool onto NC50 handling joint. Lubricate threads and inner lipof tool.

3.0 Slowly lower running tool through BOP and riser into the compact housinglanding out on top of the seal assembly.

4.0 Rotate left hand to engage tool onto seal assembly thread.

5.0 Continue rotation approximately 8 turns (see 3.0 and 6.0 on page 99) until tool isfully engaged on thread and a firm stop is encountered. The torque will increaseas the tool approaches the 8 th turn, DO NOT exceed 4,500 ft.lbf of make-uptorque as the seal assembly latch pins may be sheared. Back off from this point amaximum of 45° (1/8 th of a turn) right hand.

6.0 Retrieve seal assembly by overpull.

Note: An overpull of 15,000 lbf should be satisfactory to retrieve the assembly, DO NOT exceed 25,000 lbf.

7.0 To remove seal assembly from running tool, replace the installation tool andadjust bolt to fully compress the lockdown ring. Unscrew seal assembly righthand.
