Disclosed is a system for supplying fuel gas for a ship. The system for supplying fuel gas for a ship comprises: a vaporizer for vaporizing liquefied natural gas to supply natural gas to an engine; a first heater for exchanging heat between cooling water discharged after cooling the engine and a fluid used as a heating medium in the vaporizer to heat the fluid; and a fresh water generator for obtaining fresh water by heating sea water with a part of or the entirety of a heat source of the cooling water, which has passed through the first heater after being discharged from the engine, wherein the vaporizer exchanges heat between the heating medium having been heated by the first heater and the liquefied natural gas to vaporize the liquefied natural gas. La présente invention concerne un système permettant d'alimenter en gaz combustible un navire. Le système permettant d'alimenter en gaz combustible un navire comprend : un vaporisateur destiné à vaporiser un gaz naturel liquéfié pour fournir du gaz naturel à un moteur ; un premier dispositif de chauffage destiné à échanger de la chaleur entre l'eau de refroidissement évacuée après refroidissement du moteur et un fluide utilisé comme milieu chauffant dans le vaporisateur pour chauffer le fluide ; et un générateur d'eau douce destiné à obtenir de l'eau douce en chauffant de l'eau de mer avec une partie, ou la totalité, d'une source de chaleur de l'eau de refroidissement, qui est passée à travers le premier dispositif de chauffage après avoir été évacuée du moteur, le vaporisateur échangeant de la chaleur entre le milieu chauffant ayant été chauffé par le premier dispositif de chauffage et le gaz naturel liquéfié pour vaporiser le gaz naturel liquéfié. 선박용 연료 가스 공급 시스템이 개시된다. 상기 선박용 연료 가스 공급 시스템은, 액화천연가스를 기화시켜 엔진에 공급하는 기화기; 상기 엔진을 냉각시키고 난 후 배출된 냉각수와 상기 기화기에서 열매로 사용되는 유체를 열교환시켜, 상기 기화기에서 열매로 사용되는 유체를 가열하는 제1 가열기; 및 상기 엔진에서 배출된 후 상기 제1 가열기를 통과한 냉각수가 가진 열원의 일부 또는 전부를 이용하여, 해수를 가열하여 청수를 얻어내는 조수기;를 포함하고, 상기 기화기는, 상기 제1 가열기에 의해 가열된 열매와 액화천연가스를 열교환시켜 액화천연가스를 기화시킨다.
