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 first flow channel which is connected to an LNG storage tank of a ship, pumps and vaporizes liquid natural gas stored in the LNG storage tank, and supplies same to a first engine provided to the ship; a pressure reducing flow channel which branches out from the first flow channel, reduces the pressure of the pumped and vaporized natural gas, and supplies same to a second engine provided to the ship; and a pressure maintaining flow channel which branches out from the pressure reducing flow channel and supplies the pressure reduced natural gas to the LNG storage tank.

    L'invention concerne un système d'alimentation en carburant et un procédé pour un moteur de bateau. Le système d'alimentation en carburant pour un moteur de bateau de la présente invention comprend : un premier canal d'écoulement qui est relié à un réservoir de stockage de GNL d'un bateau, qui pompe et vaporise un gaz naturel liquide stocké dans le réservoir de stockage de GNL, et le distribue à un premier moteur disposé sur le bateau; un canal d'écoulement de réduction de pression qui se ramifie depuis le premier canal d'écoulement, réduit la pression du gaz naturel pompé et vaporisé, et le distribue à un second moteur prévu sur le bateau; et un canal d'écoulement de maintien de pression qui se ramifie depuis le canal d'écoulement de réduction de pression et distribue le gaz naturel de pression réduite au réservoir de stockage de GNL.
