To improve redundancy in a main engine in a vessel.SOLUTION: A vessel 1A includes: a hull 2; a main engine 3; an output shaft 34; a propeller 42; a propeller driving shaft 4; a motor 5; and a shaft connection/disconnection unit 7. The main engine 3 is provided in the hull 2. The output shaft 34 is rotated and driven by the main engine 3. The propeller 42 is provided outside the hull 2. The propeller driving shaft 4 rotates the propeller 42. The motor 5 is provided on the propeller driving shaft 4 and rotates and drives the propeller shaft 4. The shaft connection/disconnection unit 7 disconnects the output shaft 34 and the propeller driving shaft 4.SELECTED DRAWING: Figure 1
【課題】船舶における主機の冗長性を高める。【解決手段】船舶1Aは、船体2と、主機3と、出力軸34と、プロペラ42と、プロペラ駆動軸4と、電動機5と、軸連結断続部7と、を備える。主機3は、船体2内に設けられる。出力軸34は、主機3により回転駆動される。プロペラ42は、船体2の外部に設けられる。プロペラ駆動軸4は、プロペラ42を回転させる。電動機5は、プロペラ駆動軸4に設けられ、プロペラ駆動軸4を回転駆動させる。軸連結断続部7は、出力軸34とプロペラ駆動軸4とを断続する。【選択図】図1
