Abstract: 1,123,254. Liquefied gas storage tanks. WHESSOE Ltd. 30 June, 1966 [1 July, 1965], No. 27978/65. Heading F4P. The flat bottom 1 of a liquefied gas storage container is supported on a layer of granular heat insulating material 3, e.g. gravel, which extends outwardly beyond the periphery of the base and which is protected from ambient moisture by a layer 7 of asphalt. The roof and vertical cylindrical wall 2 of the container is lagged with heat insulation material 8 wrapped with an impervious cover 8a. The gravel 3 and asphalt 7 are retained within a steel tray 4 provided with a steam-heated tube 6. In a modification, the tray is of concrete supported by piles or by a continuous slab of concrete. The cylinder wall 2 has a plurality of peripherally spaced brackets (11), Fig. 3 (not shown), each engaged by a holding-down bolt (13) extending downwardly through a sleeve (14) in gravel layer 3 and pivoted to anchor bolts (15).
