Deep water, combined with ever-increasing actuation requirements, presents an inherent problem for subsea control systems. Storing energy in classic, pneumatic accumulators becomes less and less effective the deeper the water.
To meet API and BSEE standards using a typical subsea system:
Deeper water = More accumulators
In most subsea hydraulic systems, the accumulators are rated to higher pressures than the rest of the control system. This means that there is usable energy storage capacity in the accumulators that is presently not being taken advantage of. Accessing this extra storage capacity can be extremely beneficial in many subsea applications.
The Subsea BARS™ allows you to access the extra energy storage capacity in the subsea accumulators, without the need to increase the pressure ratings of the existing subsea piping and subsea hydraulic control system.
It’s a fully redundant pressure intensifier and pressure regulator, all-in-one:
