The Hydraulic Power Unit (HPU) is designed to provide low and high pressure filtered hydraulic fluid to topside and subsea control valves and stored volume will be provided via accumulators in the event of loss of power.

All systems are designed and tailored to suit the individual project specifications or client/SMS developed standardised design philosophies always incorporating safety, environmental and statutory requirements.
