1,226,035. Liquefied gas storage containers. CONCH OCEAN Ltd. 18 Sept., 1968 [12 Oct., 1967], No. 44324/68. Heading F4P. A non-self supporting fluid-tight cold-resistant flexible membrane tank 6 right hand side of Fig. 1, is supported against internal loads by a surrounding solid thermal insulation 5 which is itself supported by a rigid shell 2, e.g. the inner hull of a tanker and the membrane tank 6 is anchored to the insulation by rigid anglesectioned members 19, Fig. 5, which extend along and are secured to the junction of adjacent side top and bottom walls of tank 6 and referred to as corners, and members 19 are also rigidly secured to the corners of the insulation 5. The membrane tank is formed of nickel-steel corrugated sheets 16 and corrugated dihedral corner-pieces 17 and trihedral corner-pieces 17<SP>1</SP>, Fig. 4, to which are welded the angled anchor members 19 along regularly spaced intervals along the lengths of the corners of the membrane tank. Members 19 are bolted to spaced hardwood blocks 21, 22, adhesively secured to insulation panels 8 constructed as described in Specification 951,923. The spaces between adjacent hardwood blocks is occupied by balsa wood blocks 23. A modified membrane tank 41, Fig. 10, has stepped top and side walls providing internal entrant corners a and external re-entrant corners b. |
