The Proteus system is designed to maintain vertical displacement of a subsea payload to within 0.6 inch even if the surface deployment vessel, or ship, is experiencing a heave of up to 30 ft (9 m). The control system monitors vertical motions and compensates by releasing and retrieving the main winch to keep the payload still.
