To provide a ship propulsion system which has a bow thruster on a bow and a plurality of propellers on a stern, and a specific azimuth control technique which is suitable for a ship.SOLUTION: A ship propulsion system 100 includes: a bow thruster BT which is provided on a bow of a hull and generates propulsion power in a lateral direction; at least two outboard motors OM which are provided on a stern of the hull and can change a steering angle; and a main controller 50. The main controller controls the propulsion power of the bow thruster for azimuth control of controlling the azimuth of the hull, and controls the propulsion power and the steering angle of the two outboard motors. The azimuth control includes: a bow thruster mode of controlling the propulsion power of the bow thruster and adjusting the azimuth of the hull; and a combination mode of controlling the propulsion power of the bow thruster, performing forward movement operation and backward movement operation on the two outboard motors and adjusting the azimuth of the hull. The main controller is transited between the bow thruster mode and the combination mode, on the basis of a predetermined transition condition.SELECTED DRAWING: Figure 2

    【課題】船首にバウスラスタを備え船尾に複数の推進機を備える船舶推進システムおよび船舶に適した具体的な方位制御技術を提供する。【解決手段】船舶推進システム100は、船体の船首に備えられ、左右方向の推進力を発生するバウスラスタBTと、船体の船尾に備えられ、それぞれ転舵角の変更が可能な少なくとも2機の船外機OMと、メインコントローラ50とを含む。メインコントローラは、船体の方位を制御する方位制御のために、バウスラスタの推進力を制御し、2機の船外機の推進力および転舵角を制御する。方位制御は、バウスラスタの推進力を制御して船体の方位を調整するバウスラスタモードと、バウスラスタの推進力を制御し、かつ2機の船外機をそれぞれ前進運転および後進運転して船体の方位を調整する併用モードとを含む。メインコントローラは、所定の遷移条件に基づいて、バウスラスタモードと併用モードとの間で遷移する。【選択図】図2
