U BOP Hydraulic Control System

The U blowout preventer is designed so that hydraulic pressure opens and closes the ramsand provides the means for quick ram change-out.

Ram closing pressure closes the rams. When the bonnet bolts are removed, closingpressure opens the bonnet. After the bonnet has moved to the fully extended position,the ram is clear of the body. An eyebolt can be installed in the top of each ram to lift itout of the preventer.

Ram opening pressure opens the rams. Following ram change-out, this pressure closesthe bonnets. The rams are pulled outward, near the bonnets before the bonnets beginmoving toward the preventer body. This assures that the rams never obstruct the bore orinterfere with the pipe in the hole. Hydraulic pressure draws the bonnets tightly againstthe preventer body and the bonnet bolts are reinstalled to hold the bonnets closed.

Tandem Boosters for U 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 pages 11, 13, and 15.

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

U BOP Ram Hang-Off Weights andShear Requirements

Hang-Off Weights

Hang-off weights are estimated capacities withhardened top corners of the hang-off rams. Thisenables the rams to dig into the tool joint andprovide superior hang-off capacity while stillmeeting NACE requirements.

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

Drill Pipe Shearing Requirements

The minimum shearing configurations needed for each size U 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 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 BOP shearing blind rams through18-3/4”. Part numbers beginning with 644xxx indicate CAMRAM. All other top sealsare 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.

U BOP DSI and DVS Shear Rams

Dual string interlocking (DSI) shear rams and double V shear (DVS) rams are also availablefor the U BOP. The interlocking feature of these rams provides the capability of shearingwireline and braided cable with zero tension in the line, while still maintaining a seal. Theblades are interlocked by using pockets in the lower ram and arms on the upper ram toprevent any gap between blade surfaces.

DSI rams are similar to standard DS shear rams except for the interlock feature. DSIshear rams are capable of shearing tubing, small pipe, braided cable, slickline and solidsinker bar.

DVS rams are similar in design to the standard shearing blind rams except that bothblades are V shaped and interlocked. The DVS rams are capable of shearing tubing, smallpipe, braided cable and slickline.

U BOP Variable Bore Rams

One set of Cameron variable bore rams seals on several sizes of pipe or hexagonal kelly.Variable bore rams are available in the size ranges listed in the chart below. All rams listedare suitable for H2S service per NACE MR-01-75.

CAMRAM top seals are standard for all U BOP variable bore rams. CAMRAM packersare available in most sizes. Packer part numbers beginning with 644xxx indicateCAMRAM. All other packers are standard elastomer material.

The variable bore ram packer contains steel reinforcing inserts similar to those in theCameron annular BOP packer. The inserts rotate inward when the rams are closed so thesteel provides support for the rubber which seals against the pipe.

Bonnet Seal Carriers for U BOPs

The bonnet seal carrier is a bore-typesealing assembly which replaces the faceseal used as the previous bonnet seal.Sealing capability is not dependent uponbonnet bolt torque. One seal is capturedin a machined bore in the BOP bodywhile the other seal is captured in a ma-chined bore in the intermediate flange.

The seal carrier was designed, devel-oped and performance-verified for use innewly manufactured BOPs or as a re-placement seal assembly for BOPs whereeither the BOP body or the intermediateflange requires weld repair on the seal-ing surfaces.

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.

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.

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.
