A storage tank has side walls (100) each assembled from a plurality of panels (1), preferably of metal clad GRP, interconnected with one another. The panels (1) are each of hyperbolic paraboloid (“hypar”) shape thus providing a concave surface (3) which, on assembly of the tank, faces out. The tanks

A storage tank has side walls (100) each assembled from a plurality of panels (1), preferably of metal clad GRP, interconnected with one another. The panels (1) are each of hyperbolic paraboloid (“hypar”) shape thus providing a concave surface (3) which, on assembly of the tank, faces out. The tanks may be strengthened by internal bracing (500) under tension or external bracing under compression.

A fluid storage fluid tank having side walls each assembled from a plurality of panels interconnected with one another, each said panel being of hyperbolic paraboloid shape arranged to have its concave surface facing out, and each said panel having lateral edges along which run raised portions which together define a continuous flange and a plurality of spine beams extending essentially from respective mid points of the lateral edges of the panels to a reinforcing boss at a raised central region to provide interconnection between the bosses and flanges within each panel and the adjacent panels being interconnected at their flanges, means for supporting said side walls by applying support to said bosses, whereby liquid load of a filled tank on the surfaces of the respective panels is transmissible to the said flanges and spine beams which are in turn, by said support means, capable of distributing the load throughout the tank.
