Disclosed is a system for treating a boil-off gas for a ship. The system for treating a boil-off gas for a ship comprises: a first heat exchanger using, as a coolant, the boil-off gas discharged from a storage tank; a compressor compressing the boil-off gas used as the coolant by the first heat exchanger; a second heat exchanger primarily heat-exchanging and cooling the boil-off gas compressed by the compressor; a first decompression device decompressing a fluid secondarily heat-exchanged and cooled by the first heat exchanger after being primarily cooled by the second heat exchanger; a second pump pressing a liquefied gas discharged from the storage tank; and a gasifier gasifying the fluid used as the coolant in the second heat-exchanger after being pressed by the second pump, wherein the second heat exchanger heat-exchanges and cools the boil-off gas compressed by the compressor by using the liquefied gas pressed by the second pump as the coolant, and the gas gasified by the gasifier is supplied as a fuel of a first engine. The system for treating a boil-off gas for a ship increases efficiency in re-liquefying the boil-off gas.
