Title: Insulated tanks for liquefied gases

Abstract: A tank for holding liquefied gas and including a support in the form of a vertical skirt which forms a structural unity with the tank wall. The vertical skirt has an intermediate belt or zone in the region between the transition to the tank wall and the foundation, said zone being made of a bearing material which has the properties of poor heat conductivity relative to that of the material comprising the tank wall and the rest of the skirt, a thermal expansion coefficient which lies between the values for the other skirt materials, and the ability to withstand low temperatures, said zone being thermally insulated.
