To provide a ship propulsion system which achieves a fixed point holding operation capable of maintaining a position and azimuth of a hull with high accuracy, and a ship equipped with the same.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; a propeller (outboard motor OM) which is provided on a stern of the hull and can change a steering angle; and a controller (main controller 50). The controller controls the propulsion power of the bow thruster for fixed point holding control of maintaining the position and the azimuth of the hull, and controls the propulsion power and the steering angle of the propeller. The fixed point holding control includes: a translation mode of controlling the propulsion power of the propeller with the steering angle as a translation mode steering angle and holds the position of the hull, controlling the propulsion power of the bow thruster and adjusting the azimuth of the hull; and a head-turning mode of controlling the propulsion power of the bow thruster and the propeller and adjusting the azimuth of the hull with the steering angle as a head-turning mode steering angle.SELECTED DRAWING: Figure 2

    【課題】船体の位置および方位を高精度に維持できる定点保持動作を実現する船舶推進システム、ならびにそれを備える船舶を提供する。【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、転舵角の変更が可能な推進機(船外機OM)と、コントローラ(メインコントローラ50)とを含む。コントローラは、船体の位置および方位を維持する定点保持制御のために、バウスラスタの推進力を制御し、かつ推進機の推進力および転舵角を制御する。定点保持制御は、転舵角を並進モード舵角として推進機の推進力を制御して船体の位置を保持し、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並進モードと、転舵角を回頭モード舵角とし、バウスラスタおよび推進機の推進力を制御して船体の方位を調整する回頭モードとを含む。【選択図】図2
