Abstract: Disclosed is a boil-off gas system for a ship having a storage tank in which liquefied natural gas is stored and an engine using the liquefied natural gas as fuel stored in the storage tank. The boil-off treatment system for a ship comprises a first stream of the boil-off gas discharged from the storage tank after being generated from the liquefied natural gas in the storage tank; a second stream of the boil-off gas supplied to the engine as the fuel by being branched from the first stream when the amount of the first stream is more than the amount of the fuel that the engine requires; and a third stream of the boil-off gas not supplied to the engine among the first stream. The present invention can treat the boil-off gas without a reliquefication device having a refrigeration cycle by heat-exchanging the third stream with the first stream in the heat exchanger to be liquefied.
