During offshore operations in harsh sea conditions,the active heave compensation( AHC) system used on the ship-mounted crane can improve the vessel's safety and efficiency. Also the variation of the cable forces resulting from the vertical motion of the vessel can be effectively reduced due to the application of the AHC system.Hence,the crane's winch driving system is constructed based on the secondary regulated hydrostatic drive technology. And the full mathematic model of the heave compensation system is ...
