<p>An apparatus for supporting a pipe suspended over undulated sea beds, including at great depth, comprising a support module to be filled with liquid cement when positioned under said suspended pipe, and consisting of a high strength synthetic fibre fabric envelope of cushion configuration, with a rectangular base piece joined at its edges to another saddle-shaped piece acting as the top, and provided on one side with a hose fitted with a non-return valve and with a connector for connecting to an instant connection and release coupling by means of a projecting control lever, and which, strengthened and enclosed by a tubular perimetral reinforcement, is releasably and rotatably supported at a free end of a vertical articulated positioning arm constituted by three beam or trellis elements which, by means of horizontal pins, are hinged one after the other end rotatable one relative to the other about horizontal axes, the other free end of said vertical articulated positioning arm being rotatably hinged, by means of two horizontal rotation pins of which one is hollow for the passage of the liquid cement, 2. on a vertical hollow pin supported rotatable through 360.degree. about a vertical axis in a vertical tube portion welded to the end of a bracket structure fixed to a recoverable service module which is lowered by a depot ship on to the sea bed. Said vertical articulated positioning arm is also provided with an articulated positioning arm is also provided jointed pipes, which follows the configuration of said articulated arm to which it is fixed and which connects said hose of the support module to said horizontal hollow rotation pin connected by flexible conduits to the closure headpieces is connected by flexible conduits to the closure headpieces being of cone frustum shape and being clamped in a sealed manner against the ends of the respective cylindrical containers by hydropneumatically controlled cams, and being all mounted on a single carriage which slides, under hydropneumatic control, on two rails supported by said recoverable service module.</p> |
