Abstract
An underwater system for confining large volumes of liquids comprising an elongated sock-like closed container immersed in a body of water. The container has thin flexible sidewalls and is provided with an opening located adjacent the water surface. It is contemplated that the system will be used for liquids having a specific gravity about that of water so that no substantial pressure differential will exist across the container sidewalls.
Claims2
A liquid containment system comprising:
- at least two elongated closed containers constructed of flexible fluid impermeable material for storing liquids;
- said containers oriented in a generally upright manner proximate each other with each having a top portion and a bottom portion and being substantially entirely immersed within a surrounding body of water;
- said top portions including an opening providing access to the interior thereof and being supported in an uppermost position by buoyant means connected thereto for communication to the atmosphere;
- said buoyant means comprising a floating structure which supports a header assembly and conduit means in communication with each of said openings for transporting liquids into and out of said containers, said header assembly providing a plurality of passageways for transporting liquid in a predetermined manner through said conduit means;
- said containers being adapted to dispense solid materials accumulated in the bottom portion thereof wherein one of said containers includes connecting lines secured to the bottom portion thereof for drawing said portion near said top opening to facilitate the dispensation of said solid materials.
