Accumulator Units

Accumulator Unit

An Accumulator Unit is a high-pressure hydraulic system designed to store and supply hydraulic energy for the operation of Blowout Preventer (BOP) stacks and other well control equipment. It provides the hydraulic pressure required to open and close BOP rams, annular preventers, choke and kill valves, and other hydraulic devices during normal drilling operations and emergency well control situations. Accumulator Units are an essential part of every drilling rig, ensuring rapid and reliable well control to protect personnel, equipment, and the environment.

Our Accumulator Units are available for sale and lease, delivering dependable hydraulic power for onshore and offshore drilling, workover, and well intervention operations.
