The present invention relates to an inert gas supply system of floating liquefied natural gas (FLNG) comprising: a nitrogen generator for producing nitrogen gas to be supplied as a refrigerant to a liquefaction facility for liquefying natural gas, a nitrogen storage tank for storing nitrogen gas generated from the nitrogen generator, and a fluid storage tank provided to store fluid such as liquefied natural gas, wherein a nitrogen gas stored in the nitrogen storage tank is supplied to the fluid storage tank to replace the inside of the fluid storage tank. According to the present invention, it is possible to supply an inert gas to a storage tank requiring inert gas purging without a separate inert gas production facility.

    본 발명은 천연가스를 액화하기 위한 액화설비에 냉매로서 공급되기 위한 질소 가스를 생산하는 질소발생기, 상기 질소발생기로부터 발생된 질소 가스를 저장하기 위한 질소 저장탱크 및 액화천연가스를 비롯한 저장 유체를 저장하기 위해 마련되는 유체 저장탱크를 포함하고, 상기 질소 저장탱크에 저장된 질소 가스가 상기 유체 저장탱크에 공급되어 상기 유체 저장탱크의 내부를 치환하는 것을 특징으로 하는 FLNG의 불활성가스 공급 시스템으로서, 본 발명에 의하면, 별도의 불활성가스 생산시설 없이 불활성가스 퍼징을 요하는 저장탱크에 불활성가스를 공급할 수 있게 한다.
