Abstract
A flexible supportive joint is provided between a buoyancy chamber of flotation means and a sub-sea well riser conduit upon which the flotation means is mounted. In a preferred exemplary embodiment, such flexible supportive joint comprises an assembly of coaxial, telescopically oriented pipe sections with a cylindrical elastomeric member bonded therebetween to flexibly join the two sections in load bearing relation, one section being connected to the riser conduit with the other section being connected to the flotation means buoyancy chamber. In a first alternative exemplary embodiment, the flexible supportive joint is provided by a ball and socket-like connection while in a second alternative construction, the flexible supportive joint is provided by a combination of an elastomeric member in load bearing relation with coaxial conduit sections and a ball and socket-like joint between the sections.
