Disclosed is a fuel supply system for a ship. According to an embodiment of the present invention, the fuel supply system for a ship, which comprises: a fuel supply line transforming liquid fuel supplied from a fuel tank to meet the fuel supply requirements of an engine by one or more processing means, and supplying the fuel to the engine; a recollection line recollecting the unused fuel not burnt in the engine and let the fuel join the fuel supply line; a catch tank storing unused fuel purged by purging gas when the engine is normally turned off or in case of an abnormal shutdown while the ship is operating; and a gasification unit gasifying the liquid fuel stored in the catch tank and increasing pressure in the catch tank. As the liquid fuel in the catch tank is discharged by the increased pressure in the catch tank and is supplied to the fuel supply line, the fuel is used as the fuel for the engine. Therefore, unused fuel can be recollected to be supplied as fuel when the driving is resumed.

    선박의 연료공급시스템이 개시된다. 본 발명의 실시 예에 따른 선박의 연료공급시스템은 연료탱크로부터 공급받은 액상의 연료를 하나 이상의 처리수단에 의해 엔진의 연료공급조건에 맞게 변형하여, 엔진으로 공급하는 연료공급라인; 엔진에서 연소되지 않은 미사용 연료를 회수하여 연료공급라인으로 합류시키는 회수라인; 선박 운전 중 정상적인 시동 오프 시 또는 비정상적인 셧다운 시, 퍼징가스에 의해 퍼징된 미사용 연료를 저장하는 캐치탱크; 및 캐치탱크에 저장된 액상의 연료를 기화시켜 캐치탱크 내부의 압력을 상승시키는 기화부;를 포함하되, 캐치탱크 내부의 압력 상승에 의해 캐치탱크 내의 액상 연료가 토출되어 회수라인을 통해 연료공급라인으로 공급됨으로써 엔진의 연료로 사용된다.
