Disclosed are an ammonia cooling system and method for a ship. The ammonia cooling system comprises: a service tank provided in a ship with an engine receiving ammonia, to store ammonia to be supplied as engine fuel; a safety valve for preventing an increase in pressure of the service tank; and a cooling line allowing refrigerant that cools the service tank to circulate. The cooling line has: a compressor receiving and compressing ammonia gas; a cooling device cooling and liquefying the ammonia gas compressed by the compressor; and an expansion device receiving, expanding, and cooling the ammonia liquefied by the cooling device. Ammonia evaporation gas generated in the service tank is discharged to the cooling line to circulate as the refrigerant. Therefore, the ammonia cooling system can reduce greenhouse gas emissions when the ship sails.
