A structure for an underwater hull or tank which is required to withstand a high external pressure due to use at great immersion depths. The hull or tank is composed of one or more toric components formed of metal, which may be filled with a pressure-resistant material for added strength. The toric components are interconnected by connecting rings welded between adjacent toric components, and longitudinal connecting beams which are welded to the toric components and connecting rings.
A structure for a hull for underwater use and which accommodates high external pressure when immersed to great depths, comprising a plurality of toric components positioned in a series about a common axis with each component being adjacent at least one other of the components, transversal connecting rings between each two adjacent toric components, said rings being shaped to engage the outer surface of each of the two toric components between which said ring is located and being fused to said two components, and inner and outer longitudinal connecting be...
