MEMBRANE CARGO CAPACITY FOR LIQUEFIED NATURAL GAS TRANSPORTATION AND STORAGE Russian patent published in 2014 - IPC B63B25/16 F17C3/02 B21D51/24 B65D90/02 G21C13/87 

FIELD: transport.

SUBSTANCE: invention relates to transport shipbuilding, means for marine freight and storage of liquefied natural gas (LNG) and concerns design of membrane cargo capacity for its transportation and storage. Reservoir for transportation and storage of LNG includes structured thermally insulated shell mounted on carrying structure of freight vessel or capacity. The shell consists of several layers. In this structure, one layer is metal and sealed and contacts with liquefied gas being transferred or stored. The layer contains undulating corrugations. Wave tops and troughs form zigzags. Undulating indents between corrugations on the outside are filled with porous synthetic material or paste based on chopped glass fibre and binding agent.

EFFECT: higher strength and reliability of membrane cargo capacity for liquefied natural gas transportation and storage, lower probability of sealing failure.
