MOTION COMPENSATION SYSTEM |
摘要 |
A heave or motion compensation system (100) is employed on the crane (20) to compensate for the heave being experienced by a ship (22) on which the crane is mounted. The heave compensation system includes a motion reference unit (102) mounted on a distal end portion of crane arm (36) to measure the movement (acceleration) thereat. This information is transmitted to a programmable logic control processor (104) to control the operation of a winch (50) carried by the crane thereby to pay out or reel in the load line (32) of the crane. The distal end of the load line is connectable to a load being lowered or lifted by the crane.
