Tandem Boosters for UM BOPs

A BOP equipped with tandem boosters can deliver increased shearing force while not in-creasing the wear and tear on the packers. Tandem boosters approximately double theforce available to shear pipe. Since the tailrod of the tandem booster has the same strokeas the BOP’s operating piston, the standard shear locking mechanism can be installed onthe outside end of the booster. For information on lock screws and the required spacers,see page 17.

For information concerning applications where a tandem booster is required, consultyour Cameron representative.

UM BOP Ram Hang-Off Weights andShear Requirements

Hang-Off Weights

Hang-off weights are estimated capacities with hardened top corners of the hang-offrams. This enables the rams to dig into the tool joint and provide superior hang-off capac-ity while still meeting NACE requirements.

For variable bore rams (VBRs) and FLEXPACKER rams, hang-off weights up to 300,000lb (136,078 kg) on hang-off rams for the lower pipe size in the range, 600,000 lb (272,155kg) for the larger pipe size in the range.

Drill Pipe Shearing Requirements

The minimum shearing configurations needed for each size UM BOP to meet the require-ments of the second edition of API 16A are listed in the following chart. Each shearingconfiguration is capable of shearing the corresponding pipe at a closing pressure equal toor less than 2800 psi. For further information on shearing requirements for different pipesizes and grades, contact your Cameron representative.

U and UM BOP Pipe Rams

Pipe rams are available for use in Cameron UM BOPs to fit all commonly used sizes of tub-ing, drill pipe, drill collar or casing within the ranges in the charts on pages 25, 26, and 27.Cameron pipe rams include the following features:

• Cameron pipe rams are self-feeding and incorporate a large reservoir of packerrubber to ensure a long-lasting seal under all conditions.

• Ram packers lock into place and are not dislodged by well flow.• All Cameron pipe rams are suitable for H2S service per NACE MR-01-75.• CAMRAM™ top seals are standard for all U and UM BOP pipe rams from 7-1/16”

through 18-3/4” sizes. Packer part numbers beginning with 644xxx indicate theCAMRAM lipped-plate design. All other packers use standard elastomer material andreinforcement plates.

• CAMRAM 350™ packers and top seals are available for high temperature service andfor service in which concentrations of H2S are expected.

U and UM BOP Shearing Blind Rams

Cameron shearing blind rams shear the pipe in the hole, then bend the lower section ofsheared pipe to allow the rams to close and seal. Shearing blind rams can be used as blindrams during normal drilling operations.

The DS shearing blind ram can cut larger diameter tubulars or multiple tubing stringsregardless of their orientation to the centerline of the ram. A blade seal between the up-per and lower faces eliminates the need for moving pipe after shearing.

Features of shearing blind rams and DS rams include:

• Large frontal area on the blade face seal reduces pressure on the rubber andincreases service life.

• Cameron SBRs can cut pipe numerous times without damage to the cutting edge.

• The single-piece body incorporates an integrated cutting edge.

• CAMRAM™ top seals are standard for all U and UM BOP shearing blind ramsthrough 18-3/4”. Part numbers beginning with 644xxx indicate CAMRAM. All othertop seals are standard elastomer material.

• H2S SBRs are available for critical service applications and include a blade material ofhardened high alloy suitable for H2S service.

• The Cameron shearing blind ram has a single-piece body with an integrated cuttingedge.

Flexpackers for U and UM BOPs

The Cameron FLEXPACKER ram is designed to close and seal around several diameters oftubing and pipe. These packers can be used in existing Cameron BOPs. Features include:

• Stacks of metal inserts bonded into the elastomer move radially in the elastomer asthe BOP rams are closed.

As rams are energized, the proper set of metal inserts is forced against the pipe. The topplate of the packer fits the largest diameter of pipe.

VI. Maintenance Procedures

A. Routine Maintenance

1. If more than 500 psi (34.5 Bars) hydraulic pressure is required to operate theram subassemblies when there is no pressure in the well bore, determine thecause and correct any irregularities.

Caution: To avoid damage to the packers, close pipe and variable bore rams only whenpipe is in the preventer.

2. Pressure test and operate the preventer once a week per API RP53 “PeriodicField Testing” or appropriate regulatory agency requirement.

B. Periodic Maintenance

1. Once a year, or every six months in cold weather conditions, completely dis-assemble the preventer.

Note: For detailed description of disassembly, see Part III, DISASSEMBLY.

a. Clean all parts. Do not use a wire brush on sealing areas.

b. Replace all rubber seals, gaskets, and O-rings.

c. Replace ram packing according to its physical condition.

TC1542 45

d. Repair or replace damaged metal parts.

2. Reassemble the preventer.

Note: For a detailed description of assembly, see Part IV, ASSEMBLY.

a. After reassembling the preventer, test the rams and operating system. Re-fer to Part VII, TESTING for the correct procedure.

VII. Testing

A. Hydraulic Operating System

1. Test the hydraulic operating system after installation.

a. Flush the hydraulic operating system with clean operating fluid.

b. Test for proper stroking of the rams and operating system.

1) Apply a maximum of 300 psi (20.7 Bars) hydraulic pressure to the OPENport.

2) Ensure that the rams open.

3) Reduce hydraulic pressure to zero psi.

4) Apply a maximum of 300 psi (20.7 Bars) hydraulic pressure to the CLOSEport.

5) Ensure the rams close.

6) Reduce hydraulic pressure to zero psi.

c. Test for leaks in the operating system.

1) Remove the hydraulic line from the OPEN port.

Note: If testing pipe, casing, flex packers, or variable bore rams, be sure that an appropri-ate size test mandrel is installed into the preventer. DO NOT close the rams on anopen hole unless closing pressure is less than 300 psi (20.7 Bars). Flex Packers andVBRs should be tested with the largest pipe size for that packer.

2) Apply 300 psi (20.7 Bars) hydraulic pressure to the CLOSE port, and ob-serve the OPEN port for leaks.

3) Increase the pressure to 3000 psi (207 Bars) and observe the OPEN portfor leaks.

4) Inspect for leaks between the intermediate flange, the bonnet, and theBOP body. Bleed all pressure from the BOP closing line.

TC1542 46

5) Replace the hydraulic line to the OPEN port.

6) Remove the hydraulic line from the CLOSE port.

7) Apply 300 psi (20.7 Bars) hydraulic pressure to the OPEN port, and ob-serve the CLOSE port for leaks.

8) Increase the pressure to 3000 psi (207 Bars) and observe the CLOSE portfor leaks.

9) Inspect for leaks between the intermediate flange, body, and bonnet.Bleed all pressure from the BOP opening line.

10) Replace the hydraulic line to the CLOSE port.

11) Replace the seals if leaks were observed and repeat the test with newseals.

12) Repeat the procedure for each preventer.

B. Ram Test

(After installation and as required by API RP53 or appropriate regulatoryagency.)

1. Hydraulically test ram packers with water using the following procedure:

a. Install the BOP stack on a prepared test stump or install a test plug belowthe BOP if on the wellhead.

b. Inspect for ram packer leaks at low pressure by closing rams on an appro-priate size test mandrel (none if blinds or shears are used) with 1500 psi(103 Bars) operating pressure, and apply 200 psi (13.8 Bars) pressure underthe rams. Hold pressure for 3 minutes. Maximum pressure drop is 10 psi(.7 Bars) in 3 minutes.

c. Increase pressure slowly to the rated working pressure of the preventer.Hold pressure for 3 minutes. Maximum pressure drop is 100 psi (6.9 Bars)in 3 minutes.

d. If rams leak at low pressure or at working pressure, inspect for worn rampackers and replace if necessary.

e. Repeat the above procedure for each set of casing, pipe and shear rams.

VIII. Storage

A. Preventer

1. Open the bonnets and remove the ram subassemblies.

TC1542 47

2. Remove the top seals and packers, then wash the ram subasemblies.

3. Lubricate the ram bodies, covering them with a heavy grease.

Caution: DO NOT lubricate the top seals or packers.

4. Do not store the ram subassemblies inside the preventer.

Note: Rubber products that have been put into service and that are subsequently stored,will have an unpredictable shelf-life. This is attributable to their varied physical con-dition when returned to storage, due to the inability to completely removeelastomeric solvents (hydrocarbon contaminates, etc.) and storage in a containerfilled with air (chemically active gases).

5. Clean the inside and outside machined surfaces of the preventer.

6. Dry with an air blaster until no moisture is left inside or outside thepreventer.

7. Inspect the ram bores and the vertical bores for burrs.

8. Remove burrs by touching the surface lightly with a grinder using 36 to 60grit paper.

9. Lubricate the ram bore with a heavy grease.

10. Lubricate the end and outlet connection faces with a heavy grease, and coverthem with flange protectors.

11. Flush the operating system using clean operating fluid.

12. Fill the operating system with preservation fluid Cameron P/N 718100.

13. Install the 1” NPT pipe plugs into the OPEN and CLOSE connections.

Caution: DO NOT use the bonnet lifting eyes to lift a preventer.

14. To lift the preventer, use appropriately rated slings around the ends of thebody.

B. Elastomers

1. Store rubber products inside a cool, dark, and dry storage area.

a. The preferred storage temperature range for rubber goods is from 40°F to80°F (4.4°C to 26.7°C).

b. Rubber goods should be wrapped or otherwise protected from direct ex-posure to sunlight or artificial light with a high ultraviolet content (suchas fluorescent lighting). Do not store in direct sunlight even if wrapped, asoverheating will result.

TC1542 48

c. Store rubber parts in a relaxed position. Do not stretch or hang O-ringsand seals. Labels should not be attached to seals with string, wire, or tape,as these items may deform the sealing surface.

2. Use airtight containers when possible to protect against circulating air.

3. Ozone is extremely harmful to rubber. Ensure that there is no equipment inthe storage area which may generate ozone, such as mercury vapor lamps,high-voltage electrical equipment, electric motors, or any electric apparatuswhich produces arcing.

4. Keep the rubber products clean and free of solvents, oil, greases, or anyother semi-solid or liquid materials during storage. Rubber goods should spe-cifically be protected against direct contact with: manganese, copper, copperalloys (including brass), polyvinyl chloride (PVC), creosote-impregnated tim-ber, other rubber goods of different rubber compounds, sulphur, and coppernapthenate.

5. When cleaning is necessary, rubber goods may be cleaned with either soapand water or methyl alcohol. After cleaning, the rubber goods should bedried at room temperature.

6. Examine the part before installation.

Important: Rubber goods taken from storage must ALWAYS be inspected before installa-tion. Rubber goods should not be flexed at temperatures below 40°F (4.4°C).Rubber goods in storage should be inspected every 12 months to ensure thatthey are still serviceable.

a. Ensure that the part does not have a tacky surface or noticeable softeningor hardening of the surface.

b. Flex the part and inspect with a magnifying glass to ensure that there areno cracks.

c. Replace items which show any of the aging signs mentioned above.
