Disclosed is a boil-off gas treating system for a ship, which increases boil-off gas re-liquefying efficiency. The boil-off gas treating system for a ship comprises: a first heat exchanger using boil-off gas discharged from a storage tank as a coolant; 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 decompressing 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 pressurizing liquefied gas discharged from the storage tank; a gasifier gasifying the liquefied gas pressurized by the second pump; and a second decompressing device decompressing a portion of the gas gasified by the gasifier. The gas gasified by the gasifier branches into two streams such that one stream is decompressed by the second decompressing device and then used as the coolant of the second heat exchanger, the other stream is supplied as the fuel of a first engine, and the gas used as the coolant of the second heat exchanger is supplied as the fuel of a second engine.
