Our standard passive heave compensators increase the weather window for your marine operations

In general

Standard PHC units are robust, easy to implement and very easy to use. They offers excellent performance for topside and subsea applications, where the dynamic challenges can be reduced significantly by shock absorption, constant tension or overload protection.

PHC units are hydropneumatic units containing nitrogen gas and oil. These elements give the unit its spring and damping characteristics which are carefully designed to meet our clients needs for a variety of applications. Standard units normally provide excellent performance for topside and subsea applications where the functionality of shock absorption and/or overload protection is required.

Shock absorption

Safe deployment through the splash zone:

Overload protection

Overload protection in case estimated max load is exceeded.

Quick lift-off function

Increase the lift-off velocity on transfer lifts by including a Safelink PHC solution with the functionality of high pressure actuated retraction of the piston rod.
