To smoothly operate a propelling engine when starting to use LPG.SOLUTION: A vessel includes a fuel tank, a propelling engine, a fuel supply line, a pump, a fuel recovery line, a bypass line, a pressure gauge, and a control device. When the pressure of an air layer in the fuel tank detected by the pressure gauge is a predetermined value or less in a period that LPG is not used as fuel, the control device operates the pump to circulate LPG in the fuel tank via the engine and/or the bypass line to the fuel tank.SELECTED DRAWING: Figure 1

    【課題】 LPG使用開始時に推進用エンジンを円滑に運転させる。【解決手段】 船舶は、燃料タンク、推進用エンジン、燃料供給ライン、ポンプ、燃料回収ライン、バイパスライン、圧力計、および制御装置を備える。制御装置は、LPGが燃料として使用されていない期間に、圧力計で検出される燃料タンク内の気層の圧力が所定値以下であるときには、ポンプを作動させ、燃料タンク内のLPGをエンジンおよび/またはバイパスラインを介して燃料タンクへと循環させる。【選択図】図1
