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 BOPs 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.

Tandem Booster Assembly

*The 7-1/16 tandem booster is a part of the standard land and platform shear configuration for 7-1/16 U BOPs.

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 Pipe Rams

Pipe rams are available for use in Cameron U BOPs to fit all commonly used sizes of tub-ing, drill pipe, drill collar or casing within the ranges in the charts on pages 23, 24, and 25.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 BOP pipe rams from 7-1/16 through

18-3/4 sizes. Packer part numbers beginning with 644xxx indicate the CAMRAMlipped-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 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 Shearing Blind Ram

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.

Flexpackers for U 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. Thetop plate of the packer fits the largest diameter of 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.

IV. Assembly Procedure

A. Part Preparation Prior to Assembly

The work area should be clean and well lighted.

1. Remove all dirt, grit, oil, and contaminates from the ram bore, ram changepiston holes, bonnet stud holes, all fluid passageways in the body, and inter-mediate flange. Clean water and detergent should be used for cleaning.High pressure air may also be used if it is dry air.

2. Clean all internal surfaces of bonnets using clean water and detergent. Lubri-cate internal sealing surfaces.

3. Clean pistons, cylinders, and intermediate flanges, using clean water and de-tergent. Lubricate areas that will come in contact with other parts.

4. Lubricate sealing surfaces behind the threads in the bonnet stud holes in theBOP body after cleaning this area.

5. Sealed elastomer containers should not be opened until they are required forassembly. This is to prevent contamination and damage to the seal.

B. Bonnet Assembly
