To improve fuel consumption when the attitude of a ship is made to reach a target angle.SOLUTION: There are provided: two propulsion generation devices 113L and 113R provided on both sides of a hull; a helm 115 for controlling turning of the hull; a turning command acquisition part 103 for acquiring a turning command value including a turning direction and a turning amount; a speed acquisition part 107 for acquiring a speed command value of the hull; and a turning control part 111 for controlling the two propulsion generation devices 113L and 113R so that the helm 115 is at a neutral position, and propulsion of the propulsion generation devices 113L and 113R inside in the turning direction becomes smaller than propulsion of the propulsion generation devices 113L and 113R outside in the turning direction when the speed command value acquired by the speed acquisition part 107 is equal to or higher than a speed threshold, and turning a ship according to the turning command value.SELECTED DRAWING: Figure 1
【課題】船舶の姿勢を目的の角度に到達させるときの燃費を向上させる。【解決手段】船体の両側にそれぞれ設けられた2つの推進力発生装置113L,113Rと、船体の旋回を制御するための舵機115と、旋回方向及び旋回量を含む旋回指令値を取得する旋回指令取得部103と、船体の速度指令値を取得する速度取得部107と、速度取得部107が取得した速度指令値が速度閾値以上の場合、舵機115を中立位置にし、かつ旋回方向内側の推進力発生装置113L,113Rの推進力が旋回方向外側の推進力発生装置113L,113Rの推進力よりも小さくなるように2つの推進力発生装置113L,113Rを制御して旋回指令値に従って前記船舶を旋回させる旋回制御部111とを備える。【選択図】図1
