Disclosed is a fuel supply system for a ship. According to one embodiment of the present invention, the fuel supply system for the ship comprises: one or more tanks which store liquefied gas and boil-off gas of the liquefied gas; a gasifier which gasifies the liquefied gas supplied from the one or more of tanks; a first supply line which supplies gasified fluid as fuel for a first consumer; a preheater which heats the boil-off gas supplied from one or more of a first tank and a second tank; an ejector which discharges the gasified fluid at a pressure needed by a second consumer; a first operating fluid supply line which is branched from a rear end of the gasifier of the first supply line to be connected to the ejector and supplying at least some of the gasified fluid as an operating fluid of the ejector; a suction line through which the boil-off gas heated by the discharged fluid is suctioned into the ejector so as to be mixed with the fluid; and a second supply line which supplies the mixed fluid passing through the ejector as fuel for a second consumer. The present invention is able to effectively supply fuel to consumers. 선박의 연료공급시스템을 개시한다. 본 발명의 실시 예에 따른 선박의 연료공급시스템은 액화가스 및 액화가스의 증발가스를 저장하는 하나 이상의 탱크; 탱크 중 하나 이상으로부터 공급받은 액화가스를 기화시키는 기화기; 기화된 유체를 제1수요처의 연료로 공급하는 제1공급라인; 제1탱크 및 제2탱크 중 하나 이상으로부터 공급받은 증발가스를 가열시키는 프리히터; 기화된 유체를 제2수요처가 필요로 하는 압력으로 분출시키는 이젝터; 제1공급라인의 기화기 후단으로부터 분기되어 이젝터와 연결되며, 기화된 유체 중 적어도 일부를 이젝터의 작동유체로 공급하는 제1작동유체공급라인; 분출되는 유체에 의해 가열된 증발가스가 이젝터로 흡입되어 분출되는 유체와 혼합되도록 하는 흡입라인; 및 이젝터를 통과한 혼합된 유체를 제2수요처의 연료로 공급하는 제2공급라인;을 포함한다.
