VESSEL FOR TRANSPORTATION OF LIQUEFIED GASES Russian patent published in 2011 - IPC B63B25/08 B63B25/16 

FIELD: construction.

SUBSTANCE: vessel includes cargo compartments in the body, where heat-insulated prismatic tanks of liquefied gases are installed, which are made of aerated concrete, and the inner surface of their walls is lined with a sealing thin-walled coating, made of metal that ensures transportation of liquefied gas under cryogenic temperatures. Heat-insulated tanks are made as inbuilt into compartments or as inserts. The aerated concrete contains additives in the form of synthetic or metal fibre. The sealing thin-walled coating of tanks is made of metal, preferably of stainless steel or from nickel-containing, or chrome-containing alloy, or in the form of a thin-walled membrane.

EFFECT: invention provides transportation of low-temperature liquefied natural gases at long distances in case of considerable drops of gas and ambient temperatures.
