The present invention relates to a boil-off gas (BOG) re-liquefaction system and a vessel thereof, including a liquefying portion for liquefying BOG by using a mixed refrigerant. The liquefying portion includes: a re-liquefier for liquefying BOG by heat exchange with a mixed refrigerant; a mixed refrigerant compressor, which is a screw type using oil for sealing and lubrication, and which compresses the mixed refrigerant; and an oil treatment portion for separating the oil from the compressed mixed refrigerant and recirculating the resultant oil to the mixed refrigerant compressor, wherein the oil treatment portion is configured to allow at least a part of the oil to go around the mixed refrigerant compressor and to be mixed with the compressed mixed refrigerant.
