In general, liquefied natural gas refers to a cryogenic liquid which is reduced by compressing its volume to 1/600 by cooling a natural gas mainly composed of methane to minus 162 degrees. As liquefied natural gas emerges as an energy resource, an efficient transportation method that can transport a large amount from the production base to the receiving site is considered to use this gas as energy, and the result is liquefaction for sea transportation of liquefied natural gas. It appeared as a natural gas (Liquefied Natural Gas) LNG carrier.

LNG carriers need to design and build tanks that can withstand ultra-low temperatures of minus 162 degrees and require the highest level of drying technology for the entire shipbuilding industry, and classify LNG carriers according to the most characteristic type of tank. It can be divided into independent type and membrane type.

The liquefied natural gas storage tank of such a liquefied natural gas carrier has a heat dissipation panel made of two layers of urethane foam attached to the inner wall and welded a membrane inside the heat dissipation panel. The adhesive is applied to each other to attach them.
