    Disclosed is a reliquefaction system for evaporation gas of a vessel. The reliquefaction system for evaporation gas of a vessel includes: a first compressor compressing evaporation gas; a second compressor installed in parallel with the first compressor and compressing the evaporation gas of other flow, which is not transferred to the first compressor; a first heat exchanger cooling the evaporation gas compressed by the first compressor, using the evaporation gas before being compressed by the first compressor or the second compressor, as a refrigerant; a second heat exchanger additionally heat-exchanging the fluid cooled by the first heat exchanger and cooling the fluid by using the evaporation gas circulating in a refrigerant cycle as the refrigerant; a first decompressor decompressing the fluid cooled by the second heat exchanger; a first detour line enabling the evaporation gas which is scheduled to be used as the refrigerant in the first heat exchanger to detour to the first heat exchanger and directly supplying the evaporation gas to the first compressor and the second compressor; and a second detour line diverging from the first detour line and joined to the first detour line. The purpose of the present invention is to provide the reliquefaction system for evaporation gas of a vessel and a method for the same, capable of efficiently reliquefying the evaporation gas and compensating for existing problems occurring while a methane refrigeration system (MRS) is operated.
