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 the TL BOP, 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.
