Disclosed is a fuel supply system for a vessel. According to the embodiment of the present invention, the fuel supply system for a vessel includes: a first engine fuel supply line compressing evaporation gas supplied from a storage tank by a compression unit and supplying the evaporation gas to a first engine; a second engine fuel supply line supplying liquefied gas received from the storage tank to a second engine through a high pressure pump and a high pressure evaporator; a methane control line diverging from the front end of the high pressure pump of the second engine fuel supply line and supplying the separated gas ingredient as fuel for the first engine and including a regulator and a separator, wherein the regulator evaporates the ingredient with a high methane rate by heating the liquefied gas supplied from the storage tank and the separator separates the gas ingredient of the liquefied gas evaporated by the regulator from a liquid ingredient; and a reformer receiving the separated liquid ingredient and changing a heavy hydrocarbon ingredient contained in the liquid ingredient to a light hydrocarbon ingredient. The fuel supply system for a vessel stops fuel supply through the first engine fuel supply line when the pressure in the storage tank is less than a reference value. The fuel supply system for a vessel also supplies the separated gas ingredient as the fuel of the first engine through the methane control line and additionally supplies the light hydrocarbon ingredient changed in accordance with the fuel supply rate required by the first engine as the fuel for the first engine.

    선박용 연료공급시스템이 개시된다. 본 발명의 실시 예에 의한 선박용 연료공급시스템은 저장탱크로부터 공급받은 증발가스를 압축부를 통해 압축하여 제1엔진으로 공급하는 제1엔진연료공급라인; 저장탱크로부터 공급받은 액화가스를 고압펌프 및 고압기화기를 거쳐 제2엔진으로 공급하는 제2엔진연료공급라인; 제2엔진연료공급라인의 고압펌프 전단으로부터 분기되며, 저장탱크로부터 공급받은 액화가스를 가열하여 메탄가가 높은 성분을 기화시키는 조절기와, 조절기에 의해 기화된 액화가스의 기체성분과 액체성분을 서로 분리시키는 분리기를 마련하고, 분리된 기체성분을 제1엔진의 연료로 공급하는 메탄가조절라인; 및 분리된 액체성분을 공급받아, 액체성분에 함유된 중탄화수소 성분을 경질탄화수소 성분으로 변환시키는 개질기;를 포함하며, 저장탱크 내부의 압력이 기준치 미만일 경우, 제1엔진연료공급라인을 통한 연료공급을 중단시키고, 분리된 기체성분을 메탄가조절라인을 통해 제1엔진의 연료로 공급하되, 제1엔진이 요구하는 연료공급량에 따라 변환된 경질탄화수소 성분을 추가로 제1엔진의 연료로 공급한다.
