PROBLEM TO BE SOLVED: To provide a marine vessel capable of supplying a sufficient amount of fuel gas to a main gas engine and a sub-gas engine without using a high pressure pump.SOLUTION: A marine vessel comprises: a main gas engine for propulsion; a tank for accumulating a LNG; a gas supply line for introducing a BOG produced in the tank to a compressor; a first supply line for introducing the BOG discharged from the compressor to the main gas engine; a sub-gas engine for electric power generation; a liquid supply line for introducing the LNG discharged from a pump disposed in the tank to a forced carburetor; a second supply line for introducing the VG produced in the forced carburetor to the sub-gas engine; a bridge line having a first adjusting valve changeable the opening degree for introducing the VG to the gas supply line from the second supply line; a return line having a second adjusting valve changeable the opening degree for connecting to the tank from the second supply line; and a control device for controlling the first adjusting valve and the second adjusting valve.SELECTED DRAWING: Figure 1

    【課題】高圧ポンプを用いることなく主ガスエンジンおよび副ガスエンジンへ十分な量の燃料ガスを供給できる船舶を提供する。【解決手段】船舶は、推進用の主ガスエンジンと、LNGを貯留するタンクと、タンク内で発生するBOGを圧縮機へ導く送気ラインと、圧縮機から吐出されるBOGを主ガスエンジンへ導く第1供給ラインと、発電用の副ガスエンジンと、タンク内に配置されたポンプから吐出されるLNGを強制気化器へ導く送液ラインと、強制気化器にて生成されるVGを副ガスエンジンへ導く第2供給ラインと、第2供給ラインから送気ラインへVGを導く、開度変更が可能な第1調整弁が設けられたブリッジラインと、第2供給ラインからタンクにつながる、開度変更が可能な第2調整弁が設けられた返送ラインと、第1調整弁および第2調整弁を制御する制御装置と、を備える。【選択図】図1
