To easily carry out ventilation in a leakage even when fuel with greater specific gravity than air when vaporized is used.SOLUTION: A vessel has a floor partitioning an engine room into a plurality of floors. An exhaust duct and an air supply duct are formed integrally as an air supply exhaust duct. The air supply exhaust duct includes an air supply exhaust duct body extending in the vertical direction and an air supply exhaust duct extension unit branching sideways from the air supply exhaust duct body and extending along a ceiling. The air supply exhaust duct body includes an exhaust conduction opening opened in a bottom unit of a lower most floor of a plurality of floors in the engine room. An opening and closing device for opening and closing the exhaust conduction opening is provided in the exhaust conduction opening opened in the bottom unit in the lower most floor.SELECTED DRAWING: Figure 1

    【課題】気化した際に空気より比重の大きい燃料を使用した場合においても、漏洩時の換気を容易に行う。【解決手段】船舶は、機関室を複数の階に区画する床を有している。排気ダクトと給気ダクトとは、給排気ダクトとして一体に形成されている。給排気ダクトは、上下方向に延在する給排気ダクト本体と、該給排気ダクト本体から側方に分岐して天井に沿って延在する給排気ダクト延長部とを有している。給排気ダクト本体は、機械室の複数の階のうちの最下階の下部に開口する排気導入口を備えている。最下階の下部に開口する前記排気導入口には、該排気導入口を開閉する開閉装置が設けられている。【選択図】図1
