Comparison of Cameron Ram-Type Blowout Preventers 

Cameron offers a wide range of ram-type BOPs to meet the dynamic needs of the 

drilling industry. The Cameron U BOP was initially designed for underwater drilling 

and is now the most widely used land BOP. Today, there are more U BOPs in the 

field worldwide than any other ram-type BOP in the industry. As technology and the 

needs of the drilling industry changed, Cameron responded by developing new 

ram-type BOP designs. Cameron introduced the U II BOP for subsea applications and 

has since developed the T BOP and the TL, UL and UM models for land and subsea 

applications. Regardless of the model, all of the pressure containing components in 

Cameron ram-type BOPs are forged to provide added safety and reliability.

U BOP 

The Cameron U BOP is the most widely used ram-type BOP for land, platform and subsea applications 

worldwide and offers the widest range of sizes of any Cameron ram-type BOP. Like all other Cameron 

preventers, the rams in the U BOP are pressure-energized. Well bore pressure acts on the rams to increase 

the sealing force and maintain the seal in case of hydraulic pressure loss. Seal integrity is actually 

improved by increased well bore pressure. 

Other features of the U BOP include: 

• Bonnet seal carrier is available to eliminate the need for high makeup torque on bonnet bolts 

and nuts. The new 13-5/8” bodies have a bore seal. Therefore you can add the seal carrier 

without additional re-work. All other sizes require modification to accept the seal carrier. 

• Hydraulically operated locking mechanisms, wedgelocks, lock the ram hydraulically and hold 

the rams mechanically closed even when actuating pressure is released. The operating system 

can be interlocked using sequence caps to ensure that the wedgelock is retracted before 

pressure is applied to open the BOP. 

• For subsea applications, a pressure balance chamber is used with the wedgelocks to eliminate 

the possibility of the wedgelock becoming unlocked due to hydrostatic pressure. 

• Retrofit to UM Bonnet is available to provide more shearing force without the need for shear 

bonnets, large bore bonnets, or tandem boosters. 

Other features include hydraulically opening bonnets, forged body and a wide selection of rams to 

meet all applications. See page 43 for rams available to fit the U BOP.

U Blowout Preventer 


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.

Tandem Boosters for U BOPs 

A BOP equipped with tandem boosters can deliver increased shearing force while not increasing 

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 17, 19 and 21. 

For information concerning applications where a tandem booster is required, consult

UM BOPs 

The Cameron UM BOP is a lightweight blowout preventer designed for easy maintenance 

and long life. The UM complements the existing line of U preventers with interchangeable 

bonnets that can be installed on any comparable size U BOP. The 

shearing capabilities of the UM BOP bonnet is comparable to a U BOP bonnet with 

tandem boosters installed. The UM utilizes an internal booster that results in a reduced 

weight and length for the preventer and eliminates the need for external 

plumbing. The UM replaces the UL since the UM bonnet features full stroke operation 

that allows for one-step ram removal. 

Other features of the UM BOP include: 

• Bonnet seal carrier is available to eliminate the need for high makeup torque 

on bonnet bolts and nuts. 

• Same bonnet used for both shear and pipe rams. The internal shear booster 

can be reversed to act as a stroke-limiting device. 

• Internal booster provides the force necessary for shearing pipe and at the 

same time provides a reduced sealing force for long ram seal life. 

• Hydraulically operated locking mechanisms, wedgelocks, are available for 

subsea applications. 

• Most operating system seals can be replaced with the bonnet in the 

ram-change position without removing the bonnets. 

• UM utilizes the same rams as the U BOP. 

Other features include hydraulically opening bonnets, forged body and a wide selection 

of rams to meet all applications.

Tandem Booster Assembly 

SD 034536 


Tandem Boosters for UM BOPs 

A BOP equipped with tandem boosters can deliver increased shearing force while 

not increasing 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 concerning applications where a tandem booster is required, consult

U, UL and UM BOP Pipe Rams 

Pipe rams are available for use in Cameron U, UL and UM BOPs to fit all commonly used 

sizes of tubing, drill pipe, drill collar or casing within the ranges in the charts on the following 

pages. 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, UL and UM BOP pipe rams from 

7-1/16” through 18-3/4” sizes. Packer part numbers beginning with 644xxx 

indicate the CAMRAM lipped-plate design. Other part numbers may use 

standard elastomer material and reinforced plates. Verify this with your 

Cameron representative. 

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

service in which concentrations of H 2 S are expected.

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 (VBR’s) and FLEXPACKER rams hang-off data, refer to Cameron Engineering 

Bulletin 859D.

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 large diameter tubulars or multiple tubing strings regardless of 

their orientation to the centerline of the ram. A blade seal between the upper 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 TM top seals are standard for all U BOP shearing blind rams through 18-3/4”. 

• For U and UII BOPs through 18-3/4”, part numbers beginning with 644XXX indicate the 

CAMRAM lipped-plate design. Other part numbers may use standard elastomer material and 

reinforced plates. Verify this with your Cameron representative. 

• 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.

ISR Shearing Blind Ram 

Interlocking Shear Ram (ISR) is available for the U type BOP line. The ISR rams provide an improved 

shearing capacity alternative to the standard SBR rams, and should only be used when the standard 

rams cannot handle the desired shearing load. Since the geometry of the ISR ram incorporates a “V” 

shape and is designed as wide as possible, it can shear multiple strings and drill pipe as large as 6-5/8” 

OD. Also, ISR rams do not have to fold over the lower fish. This means less force is required to shear 

and, by leaving the fish open, kill mud can be pumped down the severed drill string. The interlocking 

mechanism incorporated in the ISR means that these rams can be utilized in an oversized cavity without 

fear of a leak at low wellbore pressures.

U, UL and UM BOP DSI and DVS Shear Rams 

Dual string interlocking (DSI) shear rams and double V shear (DVS) rams are also available for the U, 

UL and UM BOPs. 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, UL and UM BOP Variable Bore Rams 

(VBR and VBR-II ) 

The Cameron VBR-II is the next generation of the highly popular Cameron variable bore ram (VBR) 

packer. The patent pending VBR-II accomodates a range of pipe sizes and may be used in existing 

Cameron variable bore rams. The VBR-II seals on a range of drill pipe sizes as well as hexagonal kellys 

and provides uniform sealing pressure with virtual elimination of extrusion paths. 

As indicated in the chart below, the VBR-II is the standard VBR in most common sizes. In sizes where 

the VBR-II is not specified in the chart, the popular Cameron VBR is the standard offering. VBR-II 

packers for other size BOPs and other pipe size ranges are available upon request.

Inserted Packers 

The Cameron Inserted Packer for stripping/snubbing service is designed with a field 

replaceable, wear-resistant, non-rotating insert block. The insert block is fabricated 

from a specially formulated ultra-high molecular weight polyethelyne (UHMW-PE) 

which extends service life. The insert block is designed to be self-locking in the 

packer and should not require screws or other fasteners to hold it in place. The 

Cameron design eliminates the major causes of failure for inserted packers using 

semicircular inserts held in place with screws, including rapid insert wear out and insert 

rotation resulting in permanent packer damage.

CAMRAM 350 Packers and Top Seals for U BOPs 

CAMRAM 350 U BOP pipe ram packers and top seals are available for applications 

which require high temperature capabilities and greater H 2 S resistance than standard 

CAMRAM packers and top seals. 

CAMRAM 350 is available in all U BOP sizes in which standard CAMRAM packers and 

top seals are offered. 

CAMRAM packers in drill pipe sizes feature the Cameron patented lipped plate design. 

All packers also have chambered ends on the top and bottom reinforcing plates 

to prevent ram bore scoring and reduce elastomer extrusion.

Hydraulic Bonnet Bolt System 

The hydraulic bonnet bolt tensioner eliminates frictional and torsional loads and reduces 

the time required for making up and breaking out bonnet bolts. 

• The hydraulic bonnet bolt is completely interchangeable with conventional 

bonnet bolts. It has a standard hexagonal head. An additional external thread 

mates with the internal threads in the operating head of the hydraulic 

bonnet bolt tensioner. The hydraulic bonnet bolt has its operating rod 

permanently secured in the machined hole in the center of the bolt.

Bonnet Seals and Connecting Rod Seals 

For applications where only bonnet and/or connecting rod seals are required, 

Cameron offers individually packaged components. Connecting rod seals are nitrile 

rubber. Bonnet seals beginning with 644197 are the newest design. 

When high temperature and/or high concentrations of H 2 S are expected, Cameron 

recommends the use of CAMLAST bonnet and connecting rod seals along with 

CAMRAM 350 packers and top seals.

Bonnet Seal Carriers for U, UM and U II BOPs 

The bonnet seal carrier is a bore-type sealing assembly which replaces the face seal 

used as the previous bonnet seal. Sealing capability is not dependant upon bonnet 

bolt torque. One seal is captured in a machined bore in the BOP body while the 

other seal is captured in a machined bore in the intermediate flange. 

The seal carrier was designed, developed and performance-verified for use in newly 

manufactured BOPs or as a replacement seal assembly for BOPs where either the 

BOP body or the intermediate flange requires weld repair on the sealing surfaces.

UIIBOP 

The Cameron U II BOP takes all of the features of the U BOP and adapts them for subsea use in the 18-3/4” 

10,000 and 15,000 psi WP sizes. 

Like all other Cameron preventers, the rams in the U II BOP are pressure-energized. Wellbore pressure acts 

on the rams to increase the sealing force and maintain the seal in case of hydraulic pressure loss. Seal integrity 

is actually improved by increased well bore pressure. Other features of the U II BOP include: 

• Internally ported hydraulic stud tensioning system ensures that stud loading is consistently 

accurate and even. 

• Bonnet seal carrier is available to eliminate the need for high makeup torque on bonnet 

studs and nuts. 

• Hydraulically operated locking mechanisms, wedgelocks, lock the ram hydraulically and hold 

the rams mechanically closed even when actuating pressure is released. The operating system 

can be interlocked using sequence caps to ensure that the wedgelock is retracted before 

pressure is applied to the open BOP. 

• A pressure balance chamber is used with the wedgelocks to eliminate the possibility of the 

wedgelock becoming unlocked due to hydrostatic pressure. 

Other features include hydraulically opening bonnets, forged body and a wide selection of rams to meet all 

applications. See pages 67-70 for rams available to fit the U II BOP.

U II 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 packers and top seals are standard 

for all U II BOP variable bore rams. 

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.

U II 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. 

Features of shearing blind 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 intregal cutting egde. 

• CAMRAM TM top seals are standard for all U II BOP shearing blind rams. 

• 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.

T BOP 

The Cameron T blowout preventer offers a unique combination of benefits including safety, economy, reliability, 

extended service life, reduced height and fast and easy service. 

Side ram removal on the T BOP permits reduced stack height and facilitates change-out of rams and packers. 

Sliding the rams to the side simplifies access and handling and reduces vertical clearance requirements. 

The T BOP is available in a modular design which greatly reduces stack height. The design is possible because 

the side ram removal feature of the T BOP allows for construction of a BOP stack with virtually no extra 

space between BOP body cavities. Each BOP body or module has only a slightly raised face and gasket 

prep. 

The design of the T is based on Cameron’s experience with the highly successful U and U II ram-type BOPs 

and combines much of this proven technology including: 

• Metal-to-metal bonnet gaskets increase the safety and reliability in critical service 

applications. 

• Hydraulic stud tensioning ensures that stud loading is consistently acurate and even. 

• Hydraulically operated locking mechanisms, ST Locks, act directly on the operating piston 

tailrod and are interlocked by sequence caps to ensure that the locks are unlocked/opened 

before the BOP is opened. 

• Bonnet studs instead of bonnet bolts reduce the need to make and break threads in the BOP 

body. 

• Most operating system seals can be replaced with the bonnet in the ram change position 

without removing the bonnets. 

• The standard T BOP has a large enough piston area to shear all commonly used sizes and 

grades of drill pipe. 

Other features include hydraulically opening bonnets, forged body and a wide selection of rams to meet all 

applications. See pages 104-109 for rams available to fit the T BOP. 


T BOP Accessories 

A high-pressure, hydraulic pump system is utilized with all Cameron T BOPs for 

tensioning of the bonnet studs.

T BOP Hydraulic Control System 

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

rams and provides a means for side ram removal. 

Ram opening pressure opens the rams and closes the bonnets after ram change-out. 

The rams are pulled outward, close to the bonnets, before the bonnets begin moving 

towards the preventer body. This assures that the rams never obstruct the bore 

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

against the preventer body and the bonnet studs are hydraulically tensioned to hold 

the bonnets closed. Ram opening pressure is also used to automatically unlock the 

ST-locks. 

Ram closing pressure closes the rams. When the bonnet nuts are released, closing 

pressure opens the bonnets. When the bonnet has moved to the fully extended position, 

a ram removal tray is inserted and ram opening pressure brings the rams into 

the clear for removal. ST-locks are locked by applying pressure to the ST-lock lock 

port. This pressure wedges a piston-like assembly into position to ensure that the 

rams are locked in the closed position. An option is available where the locks are 

also locked automatically by installing a sequence valve in the system.

TL BOP 

The Cameron TL BOP product line is the result of an evolution of Cameron’s successful U, 

UII and T BOPs combined with custom features based on each customer’s specific requirements. 

All TL BOPs are based on a simplified design that eliminates the separate 

bonnet and intermediate flange design. The TL BOP features side ram removal resulting 

in a shorter BOP well-suited for rig designs with height constraints. Like all of 

Cameron’s BOPs, the TL includes hydraulically opening bonnets, forged body and a wide 

selection of rams to meet all applications. All TL BOPs feature: 

• Bonnet seal carrier eliminates the need for high make-up torque on bonnet studs 

and nuts. 

• Bonnet studs rather than bonnet bolts eliminate the need to make and break 

threads in the BOP body. 

• Side ram removal reduces stack height and simplifies ram change-out. 

• Access caps on the ram change pistons enable easier access and bonnet removal. 

• Most operating system seals can be replaced with the bonnet in the ram-change 

position without removing the bonnets because the operating cylinder and 

ram-change cylinders fit between the bonnet and end flange with tie-bolts 

holding the assembly together. 

• Piston area is large enough to shear all commonly used sizes and grades of drill 

pipe. 

• Wear pads are included on the bottom of all TL BOP rams. 

• Available in 13-5/8” 10,000 psi WP and 18-3/4” 5000, 10,000 and 15,000 psi WP 

sizes with many body configurations. 

TL Custom Features: 

• Choice of manual and hydro-mechanical locking devices, including manual lock 

screws, wedgelocks (5000 psi WP only), ST-Locks or RamLocks . 

• Choice of locking device operation/manual, semi-automatic or automatic 

operation. 

• Choice of several styles of bonnets for increased shearing capabilities such as: 

• Tandem Boosters to shear large, extra-heavy wall casing. 

• Super Shear bonnets fitted with non-sealing super shear rams for shearing drill 

collars and large casing. 

• Inconel inlays for critical sealing components. 

Due to the extensive variety of custom features, no TL BOP part numbers are included 

in this publication. Please refer to the operation and maintenance manual supplied 

with your TL BOP for specific replacement part numbers.

T and TL 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. 

Features of shearing blind 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 

integral cutting edge. 

• CAMRAM TM top seals are standard for 

all T BOP shearing blind rams. 

• 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.

T and TL BOP Variable Bore Rams 

One set of 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 packers and top seals are standard for all T and TL BOP variable bore rams. The variable bore 

ram packer contains steel reinforcing inserts similar to those in the Cameron annular BOP packer. The 

steel inserts rotate inward when the rams are closed so that the steel provides support for the rubber 

which seals against the pipe.

C BOP 

The Cameron C BOP was designed as an emergency safety head for snubbing coiled tubing workover applications. 

The main function of the C BOP is to shear whatever is in the hole - from braided cable to perforating 

guns - and forms a safe, pressure-tight seal. 

Features of the C BOP include: 

• C BOPs are compact 

• Visual position indicators clearly show the lock and unlock status, as well as the ram position 

• DSI Shear Rams shear and seal wireline, braided cable, perforating guns, gravel pack screen 

assemblies, etc. 

• Bonnet contains an auxiliary connecting rod seal for back up in emergency situations. 

• BOP can be installed in different orientations through the use of duplicate plumbing ports 

• Ram changeout is simple because of the elongated top bonnet stud 

• Provides maximum shearing capacity to ensure reliable shearing and sealing with a maximum 

closing pressure of 2800 psi achieved with a 15” diameter operating piston coupled with DSI 

Shearing Rams 

• Rams are mounted on removable buttons that may be easily changed out if required 

• Close and Lock functions are independent, allowing shearing without automatically locking - 

optional sequence valve is available 

• Rams are automatically unlocked prior to opening through the use of a sequence valve 

• High temperature seals are standard 

• Optional pressure balance chambers are available for subsea use 

• 13” flanges are available to accommodate increased bending moments

C BOP Dual String Interlocking (DSI) Rams 

DSI rams were developed to shear multiple tubing strings regardless of their orientation to the centerline 

of the ram bore. They are spring-loaded and interlocked to prevent vertical separation between 

the upper and lower blades. This feature also provides the capability to maintain a seal and 

shear wireline and braided cable with zero tension in the line. The efficient shear blade geometry on 

both upper and lower rams reduces the required shearing force. The tool steel inlayed cutting edges 

include a secondary cutting edge, which cuts and wipes away cable strands or shrapnel, which may 

have survived the initial shear edges. Clearance below the shear blade is maximized to allow the fish 

to collect when shearing large assemblies.

S/QRC and G-2 Snubbing BOPs 

The Cameron S/QRC and G-2 snubbing blowout preventers are used in well workover 

and servicing operations. S/QRCs are ram-type preventers which maintain pressure 

control for all types of workover wells. The Cameron G-2 BOP is suitable for wells requiring 

a 4-1/16” 5000 or 10,000 psi WP or 7-1/16” 5000 psi WP snubbing preventer. 

S/QRC and G-2 Rams 

Cameron S/QRC and G-2 snubbing BOPs can be equipped with the proper rams to 

perform a full range of snubbing preventer operations. 

Four types of ram bodies are available for the 4-1/16” 10,000, 15,000 and 25,000 psi 

S/QRC and 4-1/16” 5000 and 10,000 psi G-2 BOPs. These include blind, pipe, shear 

and wireline rams. Pipe rams can be fitted with safety packers, wear insert packers 

or slip inserts. Blind and pipe rams are available for all sizes. 

Features include: 

• Safety packers seal around tubing in the well bore. Tubing can be stripped or 

snubbed through these packers, if necessary. 

• Wear insert packers are for stripping and snubbing service. These subassemblies 

have a wear insert which can be easily replaced to renew the packer. 

• Slip inserts are used to hold the tubing string after shearing or during workover 

operations by supporting upward and downward forces as well as tortional 

forces. 

• Wireline ram guides have hardened steel guiding surfaces and are replaceable. 

• No special operating system is required for shearing. 

• All S/QRC and G-2 rams are suited for H 2 S service per NACE MR-01-75.

D and DL Annular Blowout Preventers 

In the unique design of the Cameron DL Annular BOP, closing pressure forces the operating piston 

and pusher plate upward to displace the solid elastomer donut and force the packer to close inward. 

As the packer closes, interlocking steel reinforcing inserts rotate inward to form a continuous support 

ring of steel at the top and bottom of the packer. The inserts remain in contact with each other 

whether the packer is open, closed on pipe, or closed on open hole. 

Other features of the DL BOP include: 

• The Cameron DL BOP is shorter in height than comparable annular preventers. 

• Available in dual configuration in certain sizes. 

• A quick-release top with a one-piece split lock ring permits quick packer change-out with no 

loose parts involved. The design also provides visual indication of whether the top is locked 

or unlocked. 

• The DL BOP is designed to simplify field maintenance. Components subject to wear are 

field-replaceable and the entire operating system may be removed in the field for immediate 

change-out without removing the BOP from the stack. 

• Twin seals separated by a vented chamber positively isolate the BOP operating system from 

well bore pressure. High strength polymer bearing rings prevent metal-to-metal contact and 

reduce wear between all moving parts of the operating systems. 

• All Cameron DL BOPs are manufactured to comply with NACE specification MR-01-75 for H 2 S 

service. 

• Packers for DL BOPs have the capacity to strip pipe as well as close and seal on almost any size 

or shape object that will fit into the well bore. These packers will also close and seal on open 

hole. Some annular packers can also be split for installation while pipe is in the hole. Popular 

sizes of the DL BOP are available with high-performance CAMULAR TM annular packing 

subassemblies. 

The Cameron DL BOP is available in sizes from 7-1/16” to 21-1/4” and in working pressures from 2000 to 

20,000 psi.

DL Annular BOP 

Replacement Part Kits 

For popular size DL BOPs, a BOP replacement parts kit is available to provide all seals, bearings 

and scrapers required during normal maintenance. 

Kit parts are shrink-film packed to prevent loss and assure long shelf life and are less expensive 

than individual parts. All parts in each kit are identified with part numbers and 

parts list index numbers. 

As an optional replacement for the standard lip seal design, a D-shaped seal is available for 

service in annular BOPs that have pitted, corroded or oversized seal grooves. To enhance 

the performance life of the used annular BOP, this seal design will fill most voids created 

by excessive wear and tear to the seal groove. Seal kits have been created which include all 

the operating system seals for the annular BOPs listed below.
