Disclosed are an LNG cargo hold testing method of a floating liquefied natural gas (FLNG) and the FLNG applied therewith. The LNG cargo hold testing method of an FLNG according to an embodiment of the present invention comprises steps of: (a) performing a first soundness test on a secondary barrier of the LNG cargo hold after the LNG cargo hold of the FLNG is built; (b) performing a cool-down operation on the inside of the LNG cargo hold; and (c) performing a second soundness test on the secondary barrier of the LNG cargo hold, wherein steps (a) to (c) are performed on the LNG cargo hold of the FLNG in a state where the FLNG is placed onshore, and the step (b) is performed using one of refrigerants excluding an LNG, thereby capable of reducing cost and increasing work efficiency.
FLNG의 LNG화물창 테스트방법 및 이를 적용한 FLNG가 개시된다. 본 발명의 실시 예에 따른 FLNG의 LNG화물창 테스트방법은 (a) FLNG의 LNG화물창 건조 이후, LNG화물창의 2차방벽에 대한 제1차 건전성 테스트를 수행하는 단계; (b) LNG화물창 내부에 대한 쿨다운 작업을 수행하는 단계; 및 (c) LNG화물창의 2차방벽에 대한 제2차 건전성 테스트를 수행하는 단계;를 포함하되, (a) 내지 (c) 단계는 FLNG를 온쇼어에 배치시킨 상태에서 FLNG의 LNG화물창에 대해 수행되고, (b) 단계는 LNG를 제외한 냉매 중 어느 하나를 이용하여 수행된다.
