Super+ type containment system is the fifth containment system in NO96 membrane LNG carrier, and the real carrier has constructed. The erection of the super+ type containment system mock-up is compulsory course before the erection of real carrier containment system. Four important technologies devoted to erection of the super+ type containment system are obtained though the analysis and research on the construction technology of super+ type containment system mock-up. A series of technical issues that maybe occur before the erection of mock-up are summarized, and put forward solutions. At the same time, technical issues are recorded and solutions are proposed during the erection process. According to the above, it can promote the high-efficiency and high-quality erection of the mock-up, and provide an important reference value for the construction of the real carrier containment system.
