Disclosed is a fuel gas supplying system of a vessel, capable of improving reliquefaction efficiency of evaporated gas. According to one embodiment of the present invention, the system comprises: a storage tank to store liquefied gas and the evaporated gas of the liquefied gas; a first evaporated gas supply line including a compression unit to compress the evaporated gas and supplying a first engine with the evaporated gas compressed by the compression unit; and a reliquefaction line receiving a part of the compressed evaporated gas to reliquefy the same. The reliquefaction line includes: a cooling unit to cool a part of the compressed evaporated gas; an expansion valve to decompress the evaporated gas cooled by the cooling unit; a gas-liquid separator to separate the evaporated gas, which passes the expansion valve to be in a gas-liquid mixed state, into gas and liquid components; and a nitrogen processing unit measuring the content of nitrogen components contained in the gas component, and circulating the gas component to the first exhaust gas supply line or supplying the gas component to a gas combustion unit (GCU), to consume the gas component based on a measurement result.

    선박의 연료가스 공급시스템이 개시된다. 본 발명의 실시 예에 의한 선박의 연료가스 공급시스템은 액화가스 및 액화가스의 증발가스를 수용하는 저장탱크, 증발가스를 가압하는 압축부를 구비하고 압축부에 의해 가압된 증발가스를 제1엔진으로 공급하는 제1증발가스 공급라인 및 가압된 증발가스의 일부를 공급받아 재액화시키는 재액화라인을 포함하고, 재액화라인은 가압된 증발가스의 일부를 냉각시키는 냉각부와, 냉각부에 의해 냉각된 증발가스를 감압시키는 팽창밸브와, 팽창밸브를 통과하여 기액 혼합상태의 증발가스를 기체성분과 액체성분으로 분리하는 기액분리기 및 기체성분에 함유된 질소성분의 함량을 측정하고 이에 근거하여 기체성분을 제1증발가스 공급라인으로 순환시키거나 GCU(Gas Combustion Unit)로 공급하여 소모시키는 질소 처리부를 포함하여 제공될 수 있다.
