Disclosed is a system for re-liquefying boil off gas for a ship. The system for re-liquefying boil off gas for a ship includes: a compressor compressing boil off gas; a second heat exchanger cooling the boil off gas compressed by the compressor; a second filter filtering lubricating oil contained in fluid cooled by the second heat exchanger; a first heat exchanger additionally cooling the fluid in which the lubricating oil is filtered by the second filter; and a decompression device decompressing the fluid cooled by the first heat exchanger. The boil off gas before being compressed by the compressor is branched into two flows so that some are used for a refrigerant in the first heat exchanger and the other is used for a refrigerant in the second heat exchanger.
