Active heave

Active heave swell compensators system

The Hydac group has delivered the active heave hydraulic system, the gas station and the control system for a dredging vessel.

Active heave winches

Hydac supplies tailor-made active heave compensation systems on winches or hydraulic cylinders that rely on the input of motion sensors. Responding to the signal from these sensors, the winches or cylinders pay in or pay out wire rope to keep the load at a constant elevation.
