Oceaneering International Delivers ‘Six Shooter’ Subsea Accumulator Module (USA)

Oceaneering International, Inc. has tested and delivered a Subsea Accumulator Module, dubbed the “Six Shooter”. The Six Shooter is six accumulators, each with 100 gallons per minute volume and rated for 7,500 psi stored pressure. The module is capable of supplying greater than 100 gallons per minute of pressurized control fluid for BOP intervention operations.

The Six Shooter Subsea Accumulator Module is deployed to rest on a mudmat or parking pile. A Remotely Operated Vehicle (ROV) actuates regulated output pressures of 5,000, 3,000, and 1,500 psi. The unit can be fully recharged subsea via an ROV or rig hotline for emergency operations and is an ideal solution for testing BOP equipment.

Each Six Shooter module is capable of delivering about 142 usable gallons of fluid at 5,000 fsw or 80 usable gallons at 10,000 fsw (7,500 psi charge, 1,500 psi MOP). Units can be “daisy chained” together to increase usable volume at depth.
