IMPAQ Technologies – Subsea Power Specialists

IMPAQ Technologies offer Subsea HPU solutions. We have a range of standard subsea HPU’s and the ability to make custom units for various applications. Most typically these are for ROV or trenching systems that vary in size.

We can also offer topside Power Distribution Units as a package solution and in previous projects have designed, built and delivered the full power circuit with complimentary control systems, valve packs and compensators from our sister companies.


Our mid-range submersible motors and hydraulic power units (HPUs) are the latest versions of a product with a 25-year track-record.

Sharing many common components and a common shaft height outputs range from 75HP
to 200HP in normal submerged operation. Ports are provided for circulating the motor oil through an external cooling system for operating outside the normal operating environment and we can assist with designing such systems.

As well as the standard, fully machined (no potentially weak castings are used) and hard anodised aluminum construction we also offer stainless steel versions using our lightweight fabricated stainless-steel housing.

Further options including water-jacket cooling are also possible.

A feature of our motor endcaps are the machined pockets to reduce weight and increase surface area for increased cooling without resorting to fins which can become clogged with silt and prevent rather than improve motor cooling.
