One embodiment of the present invention provides an ammonia fuel vessel capable of effectively disposing of ammonia when an abnormal situation of an engine occurs. According to one embodiment of the present invention, the ammonia fuel vessel comprises: a hull; a fuel tank installed on the hull and storing liquid ammonia; a first combustion engine receiving the liquid ammonia from the fuel tank through a first fuel supply pipe to generate power; a second combustion engine receiving the liquid ammonia from the fuel tank through a second fuel supply pipe to generate power; a pollutant reduction device installed on an exhaust pipe of at least one between the first combustion engine and the second combustion engine to reduce at least one between nitrous oxide and nitrogen oxide included in exhaust gas; and a recovery pipe recovering the liquid ammonia remaining in the first fuel supply pipe or the second fuel supply pipe or remaining in the first combustion engine or the second combustion engine or ammonia created as the liquid ammonia is vaporized to supply the liquid ammonia or the ammonia as a reducing agent to the pollutant reduction device.
