Abstract
Platform for use in locating and exploiting underwater deposits, e.g. of oil and/or gas of the known type having a hollow base of adjustable buoyancy, supporting a deck by means of long legs, but in which the base consists of a vessel or tank with a rigid base, the annular polygonal or rectangular periphery of which consists of one and pref. a number of annular tubes of large internal dia., the internal space in which can be filled, at least in part, with sea water or with products from the undersea deposits. Overcomes the problems of the very large draught required to float platforms with a single hollow concrete base and permits the platforms with a single hollow concrete base and permits the platform to be constructed in a dry dock or in an enclosed, but openable, sheet of water.
