Disclosed is an LNG tank maintenance and repair method of FLNG. The LNG tank maintenance and repair method of FLNG according to one embodiment of the present invention comprises a maintenance and repair gas processing method which processes the gas inside the LNG tank for the maintenance and repair of the LNG tank which is disposed to store the LNG in the FLNG. The maintenance and repair gas processing method may comprise: a first inerting and warming-up process of supplying nitrogen gas to the LNG tank in a heated state by using a nitrogen generator and an air compressor having a drying unit arranged at the FLNG; and an aeration process of supplying air to the LNG tank by using the air compressor so that the nitrogen gas in the LNG tank can be converted into air. Therefore, space utilization can be increased, and fabrication costs can be reduced.

    FLNG의 LNG탱크 유지보수 방법을 개시한다. 일 실시 예에 따른 FLNG의 LNG탱크 유지보수 방법은 FLNG에 LNG를 저장하도록 마련되는 LNG탱크의 유지보수를 위해 상기 LNG탱크 내부 가스를 처리하는 유지보수시 가스처리방법;을 포함하고, 상기 유지보수시 가스처리방법은, 상기 FLNG에 배치되는 드라잉유닛을 구비하는 공기압축기와 질소발생기를 이용하여 질소가스를 가열된 상태로 상기 LNG탱크에 공급하는 제1 이너팅 및 워밍업 작업; 상기 LNG탱크 내부의 질소가스가 공기로 치환될 수 있게 상기 공기압축기를 이용하여 상기 LNG탱크에 공기를 공급하는 에어레이션 작업;을 포함할 수 있다.
