Disclosed are a boil-off gas reliquefaction system and method for a ship. According to the present invention, the boil-off gas reliquefaction system for the ship comprises: a compressor compressing boil-off gas generated from a storage tank in the ship; a heat exchanger cooling the compressed gas compressed by the compressor; a refrigerant circulation line circulating a refrigerant supplied to the heat exchanger; a refrigerant expansion apparatus placed in the refrigerant circulation line and expanding and cooling the refrigerant supplied to the heat exchanger; a refrigerant compression unit placed in the refrigerant circulation line and compressing the refrigerant discharged from the heat exchanger after heat is exchanged; and a liquefied gas supply line supplying liquefied gas stored in the storage tank to an engine in the ship. The liquefied gas supply line is connected to the engine by passing through the heat exchanger. In the heat exchanger, heat is exchanged by and between five flows of the compressed gas, the refrigerant expanded and cooled in the refrigerant expansion apparatus, the non-compressed boil-off gas to be introduced from the storage tank into the compressor, the refrigerant compressed in the refrigerant compression unit, and the liquefied gas of the liquefied gas supply line. The present invention aims to provide a boil-off gas reliquefaction system and method for a ship, which are capable of reducing cost for installation and operation.
