Disclosed are a ship fuel supply system and method that can effectively supply fuel while effectively processing liquefied petroleum gas (LPG) recovered from an engine. The ship fuel supply system of the present invention comprises: a fuel supply line which supplies liquefied gas from a fuel supply tank provided on a ship to the ship's engine; a fuel supply pump provided in the fuel supply tank to pump the liquefied gas into the fuel supply line; a pressurizing pump provided in the fuel supply line and pressurizing the liquefied gas to the pressure required for the engine; and a return line for recovering liquefied gas not consumed by the engine among the liquefied gas supplied to the engine to the upstream of the engine. The fuel supply tank is an atmospheric pressure tank placed inside the hull of the ship. 선박의 연료공급시스템 및 방법이 개시된다. 본 발명의 선박의 연료공급시스템은, 선박에 마련된 연료공급탱크로부터 선내 엔진으로 액화가스가 공급되는 연료공급라인; 상기 연료공급탱크 내에 마련되어 상기 연료공급라인으로 액화가스를 펌핑하는 연료공급펌프; 상기 연료공급라인에 마련되며 액화가스를 상기 엔진에 필요한 압력으로 가압하는 가압펌프; 및 상기 엔진으로 공급된 액화가스 중 엔진에서 소비되지 않은 액화가스를 상기 엔진의 상류로 회수하는 리턴라인:을 포함하며, 상기 연료공급탱크는 상기 선박의 선체(Hull) 내부에 배치되는 상압식 탱크인 것을 특징으로 한다.
