One embodiment of the present invention relates to a fuel supply system for a vessel. The fuel supply system comprises: storage tanks (100, 110) containing liquefied ammonia supplied as a fuel for an engine (E) for a vessel; a first pipe (L1) connected to the storage tanks (100, 110) to supply the fuel to the engine (E); an after heater (104) connected to the first pipe (L1); a third pipe (L3) connecting the storage tanks (100, 110) with the after heater (104); a compressor (201) connected to the third pipe (L3) to pressurize boil-off gas (BOG) occurring in the storage tanks (100, 110); an economizer (204) connected to the rear end of the compressor (201) to reliquefy the BOG; a tenth pipe (L10) connecting the rear end of the compressor (201) with the economizer (204); and a heat recovery device (205) interposed between the rear end of the compressor (201) and the economizer (204) and connected to the tenth pipe (L10). Accordingly, the BOG is used to heat liquefied ammonia and, at the same time, is supplied along with the liquefied ammonia as a fuel to the engine for a vessel, thereby providing economic efficiency.
