Disclosed is a fuel supply system for a ship. According to an embodiment of the present invention, the fuel supply system for the ship comprises: a first engine fuel supply line which compresses evaporated gas supplied by a storage tank through a compression unit to supply the compressed evaporated gas to a first engine; a second engine fuel supply line which supplies liquefied gas supplied by the storage tank to a second engine through a high-pressure pump and a high-pressure gasification apparatus; a methane number control line which includes: a controller branched from a front end of the high-pressure pump of the second engine fuel supply line to heat the liquefied gas supplied by the storage tank and to gasify substances with a high methane number, and a separator which separates gas substances from liquid substances in the liquefied gas which is gasified by the controller, and which supplies the separated gas substances as a fuel for the first engine; and a second engine heavier hydrocarbon supply line which supplies the separated liquid substances to a front end of the high-pressure pump of the second engine fuel supply line. When the pressure in the storage tank is under a standard value and the first engine and second engine work, a fuel supply through the first engine fuel supply line is stopped, the separated gas substances are supplied as a fuel for the first engine through the methane number control line, and the separated liquid substances are supplied as a fuel for the second engine through the second engine heavier hydrocarbon supply line. According to the present invention, the fuel supply system for the ship is able to effectively supply fuel to meet the methane number conditions required by an 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 제2엔진연료공급라인의 고압펌프 전단으로 공급하는 제2엔진중탄화수소공급라인;을 포함하되, 저장탱크 내부의 압력이 기준치 미만이고 제1엔진 및 제2엔진 가동 시, 제1엔진연료공급라인을 통한 연료공급을 중단시키고, 분리된 기체성분을 메탄가조절라인을 통해 제1엔진의 연료로 공급하고, 분리된 액체성분을 제2엔진중탄화수소공급라인을 통해 제2엔진의 연료로 공급한다.
