Disclosed is a system for processing a liquefied natural gas in a ship, comprising a storage tank for storing liquefied natural gas, and an engine using the liquefied natural gas stored in the storage tank as a fuel. The system for processing the liquefied gas comprises (1) a first stream comprising an evaporation gas generated from the liquefied natural gas inside the storage tank and then discharged from the storage tank; (2) a second stream comprising the evaporation gas from the first stream which is supplied to the engine as the fuel; and (3) a third stream comprising the evaporation gas from the first stream that is not supplied to the engine. The first stream is compressed by a compression device and branched into the second stream and the third stream. The third stream is heat-exchanged with the first stream in a heat exchanger and liquefied, thereby processing the evaporation gas without using a reliquefication device that uses an additional coolant.
