The present invention relates to a boil-off gas (BOG) re-liquefaction system and a vessel thereof, including: a liquefied gas storage tank; a BOG compressor for compressing BOG generated in the liquefied gas storage tank; and a liquefying portion for liquefying the BOG by using a mixed refrigerant. The liquefying portion includes: a re-liquefier for liquefying the compressed BOG by heat exchange with the 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 filter for filtering out the oil from the compressed mixed refrigerant.
