Based on our experience with the U onshore ram-type BOP, U-II, and T BOP technologies, the TL offshore ram-type BOP offers the same quality, reliability, and performance in a lighter design.

Our TL BOP helps decrease downtime by simplifying maintenance. It features side ram removal and hydraulically opening bonnets that simplify ram changeout. Seal replacement does not require bonnet removal, and bonnet seal carriers eliminate the need for high makeup torque on bonnet studs and nuts. Access caps on the ram-change pistons also enable easier access from the end of the bonnet.

For improved safety and performance, ST locks and wedge locks can be interlocked with the TL BOP operating system using sequence caps to ensure the lock is retracted before applying pressure to open the BOP.
