A system and method for treating boil-off gas of a ship are disclosed. The boil-off gas treatment system includes: a first compressor receiving boil-off gas generated from liquefied gas stored in a storage tank of the ship and compressing the received boil-off gas; a second compressor compressing boil-off gas received from the storage tank; a heat exchanger cooling the boil-off gas compressed by the first compressor or the second compressor; and a refrigerant circulation line along which a refrigerant supplied to the heat exchanger is circulated, wherein the first compressor is a multistage compressor including a plurality of compressors and compressing the boil-off gas to a fuel supply pressure required for a propulsion engine of the ship, the second compressor compresses the boil-off gas to a fuel supply pressure required for a power generation engine supplied with fuel at a lower pressure than the propulsion engine, and boil-off gas compressed while passing through part of the first compressor is supplied to the heat exchanger to be cooled or is supplied to the power generation engine.
