membrane tanks for the storage and transport of fluids at low temperature.

摘要

Membrane tank having utility for the transportation and storage of liquefied gases, such as liquefied natural gas, the tank wall being comprised of two sets of warped surfaces with double curvatures, all sections of which are curved, with the surfaces of both sets being alike but having curvatures in opposite directions, some being concave and others convex in an alternating arrangement and being tangent at their common borders, each of said surfaces being anchored to a second outer wall by means of columns or partitions which project perpendicularly to a plane defined by the vertices of the warped surfaces.
