Disclosed are a fuel supply system and method for a ship engine. The fuel supply system for a ship engine of the present invention comprises: a submersible pump which is provided to an LNG storage tank of a ship for supplying LNG to the engine of the ship; a high-pressure pump which has the LNG supplied thereto from the submersible pump and compresses same under high pressure; and a return flow channel which, at the upstream of the high-pressure pump, returns the LNG to the LNG storage tank, wherein the flow of the LNG returning through the return flow channel is controlled, and the temperature of the LNG is controlled at the front end of the high-pressure pump.

    L'invention concerne un système et un procédé d'alimentation en carburant pour un moteur de bateau. Le système d'alimentation en carburant pour un moteur de bateau de la présente invention comprend : une pompe submersible qui est prévue sur un réservoir de stockage de GNL d'un bateau pour acheminer un GNL au moteur du bateau ; une pompe à haute pression pour lequel le GNL est acheminé jusqu'à celle-ci depuis la pompe submersible et le comprime sous haute pression ; et un canal d'écoulement de retour qui, en amont de la pompe à haute pression, renvoie le GNL au réservoir de stockage de GNL, l'écoulement de GNL revenant à travers le canal d'écoulement de retour étant commandé, et la température du GNL étant régulée au niveau de l'extrémité avant de la pompe à haute pression.

    선박용 엔진의 연료공급 시스템 및 방법이 개시된다. 본 발명의 선박용 엔진의 연료공급 시스템은, 선박의 LNG 저장탱크에 마련되어 LNG를 상기 선박의 엔진으로 공급하는 잠수 펌프; 상기 잠수 펌프로부터 상기 LNG를 공급받아 고압으로 압축하는 고압 펌프; 및 상기 고압 펌프 상류에서 상기 LNG를 상기 LNG 저장탱크로 복귀시키는 리턴 유로를 포함하되, 상기 리턴 유로를 통해 복귀되는 상기 LNG의 유량을 제어하여 상기 고압 펌프의 전단에서 상기 LNG의 온도를 제어하는 것을 특징으로 한다.
