EVO Compact, Offshore Ram-Type BOP | SLB


Compact, offshore ram-type BOP

25K BOP stack in the field

Introduced in 2006, the EVO compact, ram-type BOP combines engineering simplicity, footprint and operational savings, and superior reliability for improved performance in today's demanding drilling environments.

The EVO BOP design achieves a shorter, lighter footprint than standard BOPs, requiring fewer accumulator bottles without compromising power.

Its field-proven packers, seals and seal carriers, removable side ram, and hydraulically opening bonnets offer reliability and ease of maintenance.

It utilizes patented technologies, including the ROV-operable EVO-Loc BOP locking system.
