Abstract

The system transfers a load between a unit near or on the sea and a vessel by means of a crane with winch, and is partic, for use in a rough sea. The hook (17) supporting the load (18) is subjected while hoisting and lowering to a controlled wave movement in relation to the crane (13), corresponding to the relative movement between unit and vessel (19), and in synchronism with this movement. Pulleys can be provided (24-28) to detect relative movement between unit and vessel, and haul in or pay out the hoist rope in synchronism with the relative movement.
