The marine liquefied gas storage tank is mainly of three types, namely a film type, an independent B type and an independent C type. The independent C-shaped liquid tank has many advantages and few defects, so that the application range is the most extensive. However, the independent C-shaped liquid tank has smaller relative bilge and lower bilge utilization rate.

In recent years, container ships and automobile roll-on/roll-off carriers are becoming the main stream of new shipbuilding markets in addition to liquefied gas carriers. The container ship and the automobile roll-on/roll-off transport ship can only be arranged in the cabin due to the total arrangement requirement, and the fuel cabin is arranged in the cabin below the superstructure as much as possible in order to improve the cabin capacity utilization rate. Therefore, the two ship-shaped matched fuel tanks are more selected from a film type and an independent B type before, and the shape is a flat and short octahedral prism, namely, the length of the tank body is smaller than the relative width and the height of the tank body. However, the popularization and application of the system are limited due to the defects of long design period, special evaporation gas treatment system and the like. Therefore, there is an urgent need in the market for a new type of tank to meet the requirements of both types of ship-shaped fuel tanks.
