Abstract
Abstract A TANK A RELATIVELY FLEXIBLE SIDE WALL ENCLOSED BY A JACKET THAT HAS RIGID SIDE WALL SPACED FROM THE TANK WALL. RIGID PANELS ENCIRCLING THE TANK WALL IN ENGAGEMENT WITH IT ARE SPACED FROM THE JACKET SIDE WALL BY MEANS OF VERTICAL STRUTS. THE PANELS AND STRUTS ARE MADE OF MATERIAL OF VERY LOW HEAT CONDUCTIVITY AND TRANSFER THE OUTWARD PRESURE OF THE FILLED TANK TO THE JACKET SIDE WALL. THE SPACE BETWEEN THE PANELS AND THE JACKET IS FILLED WITH THEREMAL INSULATION. THE TANK IS PROVIDED WITH EXPANSION JOINTS TO ALLOW ITS SIDE WALL TO REMAIN AGAINST THE PANELS UNDER ALL CONDITIONS.
