Disclosed are a boil-off gas reliquefaction system for a ship and a method thereof. The boil-off gas reliquefaction system for a ship comprises: a compressor for compressing boil-off gas generated from a storage tank in a ship; a heat exchanger for cooling the compressed gas compressed by the compressor; a refrigerant circulation line through which the refrigerant supplied to the heat exchanger circulates; a refrigerant compression unit provided in the refrigerant circulation line to compress the refrigerant discharged after heat exchange in the heat exchanger; and a cold and heat recovery heat exchanger for receiving the compressed refrigerant from the refrigerant compression unit and exchanging heat between the compressed refrigerant and uncompressed boil-off gas discharged from the storage tank. The boil-off gas discharged from the storage tank is introduced into the compressor through the heat exchanger after the exchange of heat between the boil-off gas and the refrigerant in the cold and heat recovery heat exchanger. Therefore, reliquefaction performance can be increased by cooling boil-off gas to be reliquefied through more effective heat exchange.
