PROBLEM TO BE SOLVED: To provide an arithmetic control unit for controlling a floating crane which can prevent a suspended load thrown by a crane from becoming unstable on a water surface or in water or flowing when a plurality of propelling machines hold a hull at a fixed point.;SOLUTION: An arithmetic control unit 40 controls a floating crane 100 which includes a hull 10, a crane 30 which is provided rotatably to the hull 10 and throws a suspended load 101 on a water surface or into water, and a propelling system which is configured redundantly of a plurality of propelling machines 21 to 24. The arithmetic control unit 40 performs the fixed point holding control of the hull 10 while executing limited operation for reducing the quantity of water jetted from the propelling machines 21 to 24 to the throwing position of the suspended load 101.;COPYRIGHT: (C)2013,JPO&INPIT
