Abstract
Pipe system for collecting petroleum from off-shore wells located at great depths comprises flexible pipes connecting well head to a float comprising an at least partially submerged caisson which contains air so as to maintain the flexible pipes under tension. Rigid pipes within the caisson lead from the flexible pipes to a discharge opening in a superstructure which projects above the surface of the sea.
