High-Temperature Variable-Bore Rams
H2S and high-temperature applications
Provide a seal to a range of diameters, and are suited for H2S service per NACE MR0175 and compatible with U surface ram-type BOP.
EVO
Compact, offshore ram-type BOP
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.
