Reel Power ME patented innovative depth compensated accumulators reduce subsea equipment
weights, lowers maintenance requirements and improves equipment access. Accumulators are used to
deliver hydraulic fluids to a wellhead blowout preventer, subsea control systems and subsea trees.
Among other functions, accumulators are used to actuate the shear rams on a subsea BOP stack.

Accumulators are used to deliver hydraulic fluids to a wellhead blowout preventer, subsea control
systems, and subsea trees. Among other functions, accumulators are used to actuate the shear rams on
a subsea BOP stack.
The patented Depth Compensated Accumulators use the pressure of the ocean’s water column to boost
the hydraulic pressure, thereby allowing a fewer number of accumulator bottles mounted in the subsea
system. In some cases, the number of bottles can be reduced by over 90%.

The Depth Compensated technology provides a fixed volume output regardless of the changes from the
surface to subsea temperatures and regardless of operating depth. The volume output is consistent and
predictable every time. The Depth Compensated Accumulators perform subsea exactly as they do on the
surface. Conventional accumulators offer significantly lower volume output at subsea due to changing
temperatures and pressures at subsea compared to the surface. In some cases, conventional
accumulators have only 15% of the volume at subsea as they have at the surface or less in deeper
waters.
