Pressure Compensators

Pressure compensators are used in all subsea hydraulic systems to negate the effects of pressure differential at depth. The compensation maintains a constant slightly higher oil pressure within the hydraulic system, regardless of depth. It also provides the initial head pressure the hydraulic pump requires for startup without cavitation. Typically around 12 PSI. The design of the compensator ensures this slight over-pressure is maintained for all water depths, from surface to full ocean depth.

Compensators are also used on electrical enclosures to prevent collapse at depth. The enclosure is oil-filled & all air is bled from the system. The compensator is attached to automatically maintain a constant, slight over-pressure, regardless of depth. Typically 5PSI, 10PSI or 15 PSI.

As the internal oil is for all intents & purposes incompressible, this removes the external pressure differential when the enclosure is submerged and prevents enclosure collapse. This method allows lighter, thin wall enclosures to be used, as opposed to heavy thick walled pressure resistant enclosures, thus reducing the overall weight of the equipment.

Also by utilizing a slight over-pressure, this ensures that in the event of a leak, oil will leak out of the system before water is drawn in. Integral measurement transducers, built in to the compensator unit, monitor stroke (leakage) and give for-warning of any problems to the equipment operator, allowing for a timely recovery of the equipment before major damage occurs

Clearview style unit ss316

Deep-Sea Pressure Housings

PT. Marine Propulsion Solutions, is a subsea engineering company who designs and manufactures affordable, harsh environment aluminum, stainless steel and Titanium enclosures for housing electrical components to full ocean depth.

MPS’s enclosures are often used for thruster motor controllers, batteries, lights, camera, laser, hydrophones, data-loggers and other sensing and monitoring equipment, instrumentation housings, junction boxes, underwater camera enclosures, general subsea enclosures with internal/external mounting brackets.

We offer multiple families of pressure housings which live up to their pressure rating. which can have many underwater connector interfaces and are used extensively with Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs) and for many other applications in the oil and gas industry, defense, research, environmental monitoring and offshore renewables.
