ABSTRACT:
A portable submerged structure uses fluid pressure to extend a plurality of lexible conduits until the conduits become rigid. In such a rigid configuration the flexible conduits provide a rigid support which is independent of any further moorings or other conventional structure used to obtain rigidity. The invention discloses the use of an open form of independent conduits as well as conduits which are joined to provide a closed geometric figure. A packaging and deploying system using a fluid released container is also disclosed.
