30T Active Heave Winch

The AHC winch system (comprising winch container and HPU) is specially designed for load handling from a vessel or a rig towards the seabed, underwater installations or other fixed targets on the seabed. Active heave compensation (AHC) is used to control the relative position of a load to a fixed object The position is determined by the control system using a real-time signal from a motion reference unit (MRU) as an input. In response to this signal the AHC system will pay in or pay out to keep the load at a constant distance from the seabed or other fixed target.
