The present invention relates to a boil-off gas re-liquefaction system, and a ship. The present invention has a liquefied portion for liquefying boil-off gas using mixed refrigerants. Moreover, the liquefied portion comprises: a mixed refrigerant compressor for compressing the mixed refrigerants; a re-liquefaction apparatus for liquefying the boil-off gas by exchanging heat with the mixed refrigerants; and a decompression valve for allowing the mixed refrigerants heat-exchanged from the re-liquefaction apparatus to be decompressed so as to be re-introduced into the re-liquefaction apparatus. The liquefied portion further has a mixed refrigerant bypassing unit which delivers the mixed refrigerants, delivered from the re-liquefaction apparatus to the mixed refrigerant compressor, to downstream of the mixed refrigerant compressor using at least a portion of the mixed refrigerants delivered from the mixed refrigerant compressor to the decompression valve.
