Disclosed is an evaporation gas reliquefaction system for a vessel. The evaporation gas reliquefaction system for a vessel includes: a compressor compressing evaporation gas; a heat exchanger exchanging the heat of the evaporation gas compressed by the compressor and cooling the evaporation gas, using the evaporation gas before being compressed by the compressor as a refrigerant; an oil separator installed in the upper part of the heat exchanger and separating the oil included in the evaporation gas compressed by the compressor; a first oil filter installed in the upper part of the heat exchanger and separating the oil included in the evaporation gas passing through the oil separator; a second oil filter installed in the upper part of the heat exchanger and separating the oil included in the evaporation gas passing through the first oil filter; a decompression device decompressing a fluid cooled by the heat exchanger; and a third oil filter installed in the lower part of the decompression device and filtering lubricating oil solidified and mixed in the evaporation gas.
