As shown in fig. 1, on a membrane type LNG carrier, liquid gas cargo 2 is surrounded by a containment system 3, and the containment system 3 is provided in a hull structure 1, where the containment system 3 is referred to as a membrane type containment system. The specific structural design of the thin film type cargo containment system is shown in fig. 2, and the thin film type cargo containment system comprises a first sealing shielding layer 4, a suspension magnet 5, a guide magnet 6, a second sealing shielding layer 7, an insulation module 8, low temperature resistant plywood 11, low temperature resistant epoxy resin 9, a low temperature resistant fastener 12 and low temperature resistant glass wool 10.
The first sealing shielding layer 4 is in direct contact with the liquid gas cargo 2 and is arranged on the innermost layer of the film-type cargo containment system, and considering that the film-type cargo containment system can load various types of liquid gas cargo 2 and needs to bear stress caused by thermal expansion and cold contraction, invar steel is preferably selected as a manufacturing material of the first sealing shielding layer 4.
As shown in fig. 3, 4 and 5, the levitation magnet 5 is disposed outside the first sealing and shielding layer 4 and is connected to the first sealing and shielding layer 4 by welding, so as to form a levitation module. The adjacent suspension modules are connected in a welding mode, and a plurality of suspension modules finally form a closed space for bearing liquid gas cargos 2. The levitating magnet 5 is a T-shaped permanent magnet material, but the levitating magnet material may be modified depending on the form of levitation selected. The guide magnet 6 is a concave electromagnet, and the guide magnet 6 is arranged in a groove of the low-temperature resistant plywood 11 at the top of the insulating module 8. The guiding magnet 6 is fixed with the insulating module 8 through a low-temperature stainless steel connecting piece to form a guiding insulating module, and the manufacturing material of the guiding magnet 6 can be changed according to the selected suspension form. The guiding insulation modules are arranged in an array form at the outer side of the first sealing shielding layer 4 to form a magnetic suspension force bearing surface to generate magnetic suspension force, one surface after arrangement is shown as figure 7, and figure 7 is a schematic layout view of the guiding insulation modules in the planar area of the magnetic suspension film type cargo containment system in the embodiment of the invention.
As shown in fig. 6 and 7, the suspension module forms a completely closed space by welding, the suspension module forms a closed loop along the ship length direction, the suspension magnets 5 on the suspension module correspond to the guide magnets 6 on the guide insulating module one by one, the guide magnets 6 are arranged outside the suspension magnets 5 and cooperate with the suspension magnets 5 to realize the magnetic suspension function, and a certain gap is left between the guide magnets 6 and the suspension magnets 5, and the gap is not larger than the maximum interval of failure of the magnetic suspension function. The guiding magnet 6 is connected with the insulating module 8 through a low temperature resistant fastener 12, and in order to ensure the reliability of the connection, low temperature glue can be added or more low temperature resistant connecting pieces 12 and the same type thereof can be adopted.

The first shielding space can be filled with liquid nitrogen or low-temperature inert gas to provide a positive-pressure inert environment for the enclosure system. During specific application, thereby the first shielding space is formed by filling liquid nitrogen between the first sealing shielding layer 4 and the second sealing shielding layer 7, the liquid nitrogen can enable the whole first sealing shielding layer 4 and the liquid gas cargo 2 to be in a cryogenic environment at-196 ℃, volatilization of the liquid gas cargo is reduced, and volatile gas of the liquid nitrogen can enter the second shielding space.

In the process of ship sloshing, the suspension cargo hold has a damping effect, and the ship body is kept stable. The magnetic levitation technology may be any one of a diamagnetic levitation technology, a superconductive repulsion levitation technology, and the like, and is intended to ensure that a certain gap is always maintained between the levitation magnet 5 and the guidance magnet 6 in a ship sailing state or a harbor berthing state, and to reduce the influence of the sloshing of the hull structure 1 on the liquid gas cargo 2 during the sloshing of the ship.
