Disclosed is a system for re-liquefying boil off gas for a ship. The system for re-liquefying boil off gas for the ship includes: a compressor compressing the boil off gas; a heat exchanger exchanging heat to cool the boil off gas compressed by the compressor by using the boil off gas before being compressed by the compressor as a refrigerant; a decompressing device decompressing fluid cooled by the heat exchanger; and a second filter installed in a downstream portion of the decompressing device to filter solidified lubricating oil mixed in the boil off gas, wherein the second filter is installed at a point in which the temperature of the boil off gas is the lowest.
