Description

The subsea HPU (SHPU) is an electro-hydraulic pump designed to provide control fluid, grease
and other hydraulic fluids for power and control applications subsea. It is a modular, integrated
design, with advanced motor drive, electrical motor and hydraulic pump integrated in one unit.
The modular design approach allows each section – drive, motor and pump – to be individually
interchanged. This allows the system to be used as pump for different types of fluids – e.g.
water-glycol control fluids, grease, hydraulic oil – simply by replacing the pump. This also allows
for easy field servicing and configurability.
The units are built and tested according to customer specifications, and qualified to ISO 13628-6
for subsea control applications. The electrical systems have dual barriers to sea.
Remote control of the SHPU is done via an integrated intelligent motor drive system, with semi
automatic functions to allow the system to maintain a set pressure. With extensive diagnostics
and monitoring systems, the SHPU can work in autonomous and semi-autonomous modes.

The electrical motor is an AC motor enclosed in a sealed, oil filled, pressure compensated chamber.
The system is equipped with sensors to monitor voltage, current, pressures and temperature during
operation. Operational data is provided online, and can be stored for condition monitoring and analysis.

The SHPU can be configured to customer specifications and have been delivered in the following
configurations:
HP Water-glycol 690 bar
LP Water-glycol 345 bar
HP Grease 690 bar
LP Grease 100 bar
