SHIP

A ship comprises: a hull; an ammonia storage tank in which ammonia can be stored; an inert gas supply device that supplies an inert gas to an ammonia circulation path that communicates with the ammonia storage tank; a vent tube that guides the ammonia in the circulation path to the outside together with the inert gas supplied by the inert gas supply device; and a processing tank provided midway along the vent tube, water being stored inside the processing tank, and the inert gas and ammonia being introduced into the processing tank from the vent pipe below the surface of the water.
