Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings which form a part hereof. The same reference numerals in the figures denote the same components.

[0031] figure 1 A schematic structural diagram of a liquefied gas tank to which the method for detecting the stability of a secondary barrier according to an embodiment of the present invention is applied is illustrated.

[0032] Such as figure 1 As shown, the liquefied gas tank 10 includes a primary barrier 100 and a secondary barrier 200 . Due to the existence of the primary barrier 100 and the secondary barrier 200, an inter-barrier space IBS and an isolation space IS are formed. The inter-barrier space IBS and isolation space IS are connected to a nitrogen booster system that supplies nitrogen to the IBS and IS spaces through nitrogen supply control valves 110 and 210 . In addition, the inter-barrier space IBS and the isolation space IS are connected t...

Abstract

A test method for soundness of a secondary barrier in a liquefied gas tank includes the steps of: (A) observing an integrated automation system; (B) performing a first differential pressure test when abnormality is observed through the observation in the step (A); and (C) performing, when a pressure in an insulation space and a pressure in an inter-barrier space are not equal to each other or pressure reversal occurs after the pressures become equal to each other as a result of the first differential pressure test in the step (B), a second differential pressure test. The test method further includes: (D) performing, when the pressure in the insulation space and the pressure in the inter-barrier space are equal to each other as a result of the second differential pressure test in the step (C), a third differential pressure test.

Description

technical field [0001] The invention relates to a detection method for the soundness of a secondary barrier in a liquefied gas tank, which is capable of evaluating the soundness of the secondary barrier in a liquefied gas tank of a ship in operation. Background technique [0002] There are two main known methods of transporting natural gas, an attractive clean fuel, from production areas to consumption areas: gaseous natural gas by pipeline; and liquid natural gas by ship. [0003] Natural gas is transported by pipeline, and for long-distance transportation, the gas needs to be handled at high pressure, and the pipeline needs to be continuously maintained and repaired. Furthermore, the installation of pipelines is heavily influenced by geopolitical issues. [0004] Recently, in order to overcome the above-mentioned problems, a method of transporting natural gas by ships is widely used. In particular, with the development of extremely low-temperature object storage technolo...
