U BOP Hydraulic Control System

The U blowout preventer is designed so that hydraulic pressure opens and closes the rams

and provides the means for quick ram change-out.

Ram closing pressure closes the rams. When the bonnet bolts are removed, closing

pressure 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 it

out of the preventer.

Ram opening pressure opens the rams. Following ram change-out, this pressure closes

the bonnets. The rams are pulled outward, near the bonnets before the bonnets begin

moving toward the preventer body. This assures that the rams never obstruct the bore or

interfere with the pipe in the hole. Hydraulic pressure draws the bonnets tightly against

the preventer body and the bonnet bolts are reinstalled to hold the bonnets closed.

-U BOP Specifications and Accessories

The following specifications apply to typical Cameron U type BOPs. Your Cameron

repre-sentative can provide information on non-standard BOP assemblies.

• Side outlets to 4-1/16” (7-1/16” on 26-3/4” BOPs) can be provided beneath each set

of rams on either or both sides of U BOPs. Side outlets can be studded, open-face

flange or clamp hub with the same pressure rating as the vertical run connections.

• Flanges conform to API standard 6A and/or 16A. Hubs conform to API 16A or

applicable standards. Type 6BX flanges are standard for 10,000 and 15,000 psi

working pressures and for 5000 psi for 13-5/8” and larger bore BOPs.

• Hydraulic control connections for operation of rams and bonnets are 1” NPT. There

are two connections for each set of rams. Wedgelock connections are ½” NPT.

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 the

force available to shear pipe. Since the tailrod of the tandem booster has the same stroke

as the BOP’s operating piston, the standard shear locking mechanism can be installed on

the 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, consult

your Cameron representative.

U BOP Ram Hang-Off Weights and

Shear Requirements

Hang-Off Weights

Hang-off weights are estimated capacities with

hardened top corners of the hang-off rams. This

enables the rams to dig into the tool joint and

provide superior hang-off capacity while still

meeting NACE requirements.

For variable bore rams (VBRs) and

FLEXPACKER rams, hang-off weights up to 300,000 lb (136,078 kg) on hang-off rams for

the lower pipe size in the range, 600,000 lb (272,155 kg) for the larger pipe size in the

range.

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 shearing

configuration is capable of shearing the corresponding pipe at a closing pressure equal to

or less than 2800 psi. For further information on shearing requirements for different pipe

sizes 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 packer

rubber 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 H

2

S 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 CAMRAM

lipped-plate design. All other packers use standard elastomer material and

reinforcement plates.

• CAMRAM 350™ packers and top seals are available for high temperature service and

for service in which concentrations of H

2

S are expected.

U BOP Shearing Blind Rams

Cameron shearing blind rams shear the pipe in the hole, then bend the lower section of

sheared pipe to allow the rams to close and seal. Shearing blind rams can be used as blind

rams during normal drilling operations.

The DS shearing blind ram can cut larger diameter tubulars or multiple tubing strings

regardless 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 and

increases 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 through

18-3/4”. Part numbers beginning with 644xxx indicate CAMRAM. All other top seals

are standard elastomer material.

• H

2

S SBRs are available for critical service applications and include a blade material of

hardened high alloy suitable for H

2

S service.

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

edge.

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 available

for the U BOP. The interlocking feature of these rams provides the capability of shearing

wireline and braided cable with zero tension in the line, while still maintaining a seal. The

blades are interlocked by using pockets in the lower ram and arms on the upper ram to

prevent any gap between blade surfaces.

DSI rams are similar to standard DS shear rams except for the interlock feature. DSI

shear rams are capable of shearing tubing, small pipe, braided cable, slickline and solid

sinker bar.

DVS rams are similar in design to the standard shearing blind rams except that both

blades are V shaped and interlocked. The DVS rams are capable of shearing tubing, small

pipe, 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 listed

are suitable for H

2

S service per NACE MR-01-75.

CAMRAM top seals are standard for all U BOP variable bore rams. CAMRAM packers

are available in most sizes. Packer part numbers beginning with 644xxx indicate

CAMRAM. All other packers are standard elastomer material.

The variable bore ram packer contains steel reinforcing inserts similar to those in the

Cameron annular BOP packer. The inserts rotate inward when the rams are closed so the

steel 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 of

tubing 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 as

the BOP rams are closed.

• As rams are energized, the proper set of metal inserts is forced against the pipe. The

top plate of the packer fits the largest diameter of pipe.
