CONTROL METHOD FOR TWIN-SCREW VESSEL AND TWIN-SCREW VESSEL

PROBLEM TO BE SOLVED: To provide a twin-screw vessel with a pair of propellers connected with individually controllable drive sources, the vessel being capable of optionally adjusting a rotational phase difference cross a pair of propellers.SOLUTION: In a control method for the twin-screw vessel 1 with a pair of propellers 4, 5 connected with individually controllable drive sources 2, 3, the drive source 2 of one propeller 4 is controlled so that a rotational speed of one of the pair of propellers 4, 5 is a target rotational speed, and a rotational phase difference between the pair of propellers 4, 5 is calculated, and the drive source 3 of the other propeller 5 is controlled so that a rotational speed of the one propeller 4 of the pair of propellers 4, 5 is a target rotational speed.
