According to one embodiment of the present invention, provided is a fuel supply system for a vessel, which comprises: storage tanks (100, 110) storing liquefied ammonia supplied as fuel to 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) and 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 re-liquefy the BOG; a twelfth pipe (L12) connecting the economizer (204) and the storage tanks (100, 110); and a heat recovery device (205) interposed between the economizer (204) and the storage tanks (100, 110) and connected to the twelfth pipe (L12). 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 of a vessel, thereby providing economic efficiency.
