T BOPThe 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 becausethe side ram removal feature of the T BOP allows for construction of a BOP stack with virtually no extraspace between BOP body cavities. Each BOP body or module has only a slightly raised face and gasketprep.The design of the T is based on Cameron’s experience with the highly successful U and U II ram-type BOPsand combines much of this proven technology including:• Metal-to-metal bonnet gaskets increase the safety and reliability in critical serviceapplications.• Hydraulic stud tensioning ensures that stud loading is consistently acurate and even.• Hydraulically operated locking mechanisms, ST Locks, act directly on the operating pistontailrod and are interlocked by sequence caps to ensure that the locks are unlocked/openedbefore the BOP is opened.• Bonnet studs instead of bonnet bolts reduce the need to make and break threads in the BOPbody.• Most operating system seals can be replaced with the bonnet in the ram change positionwithout removing the bonnets.• The standard T BOP has a large enough piston area to shear all commonly used sizes andgrades of drill pipe.Other features include hydraulically opening bonnets, forged body and a wide selection of rams to meet allapplications.
