Title: TWO BODY MOTION COMPENSATION SYSTEM FOR MARINE APPLICATIONS
Abstract:
A motion compensation system employs a power winch, at least one sensor, and a control system that are used for moving a payload from, for example, a supply vessel to a platform of an oil rig. Prior to connecting a lifting hook to a payload, the compensation system automatically adjusts the positioning of the hook relative to the deck of the supply vessel, which during inclement weather conditions at sea, makes it easier for deck workers to tether the lifting hook to the cargo.
