T BOP

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

ability, 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 pack-

ers. 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 be-

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

tra 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 accurate 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 114-120 for rams available to fit the T BOP.

T BOP Accessories

A high-pressure, hydraulic pump system is utilized with all Cameron T BOPs fortensioning of the bonnet studs.

T BOP Hydraulic Control System

The T blowout preventer is designed so that hydraulic pressure opens and closes therams and provides a means for side ram removal.

Ram opening pressure opens the rams and closes the bonnets after ram change-out. Therams are pulled outward, close to the bonnets, before the bonnets begin moving to-wards the preventer body. This assures that the rams never obstruct the bore or inter-fere with pipe in the hole. Hydraulic pressure draws the bonnets tightly against thepreventer body and the bonnet studs are hydraulically tensioned to hold the bonnetsclosed. 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 pres-sure opens the bonnets. When the bonnet has moved to the fully extended position, aram removal tray is inserted and ram opening pressure brings the rams into the clear forremoval. ST-locks are locked by applying pressure to the ST-lock lock port. This pressurewedges a piston-like assembly into position to ensure that the rams are locked in theclosed position. An option is available where the locks are also locked automatically byinstalling a sequence valve in the system.
