[0002] As a key component of the storage tank of liquefied natural gas (LNG) carriers, the main function of the marine membrane enclosure system is to protect the inner wall of the tank from direct contact with low-temperature LNG, while ensuring the good insulation performance and pressure resistance of the structure. The membrane enclosure system mainly includes a membrane shielding layer, an insulation module, and an anchoring system. The anchoring system is used to connect the membrane shielding layer and the insulation module. During the construction of the membrane shielding layer, a large number of corrugated plates should be assembled and welded according to the design requirements. After the welding is completed, a strict sealing test is required to ensure that there is no risk of leakage during LNG storage.

[0003] At present, people usually use ammonia colorimetric detection to test the sealing of two adjacent corrugated plate welding positions; the specific detection steps are to stick phenolphthalein test paper on the side of the weld that is easy to observe, and the width of the test paper is slightly wider than the weld to ensure that all possible leakage areas are covered; then fill the weld position with ammonia mixed gas through the other side of the weld; if there is a defect at the welding position, ammonia will leak through the defect to the outer wall and react with the test paper to produce red stripes, so that the staff can repair the welding defects.

[0004] However, since the area of ​​multiple corrugated plates is large and the weight is heavy after welding, it is inconvenient for the staff to stick phenolphthalein test paper on one side of the welding position and flush ammonia mixed gas on the other side, which reduces the detection efficiency and needs to be improved.
