Abstract

Support is for positioning sub-marine conduits. Conduits are fixed on a support comprising at least one girder lattice at the ends of which are fixed floats. Alternatively a structure carries two expandable floats. The height of the support separates the conduits from the sea bed. Used for positioning sub-marine conduits with the aid of floats.
