APPARATUS FOR SUPPORTING PIPES SUSPENDED OVER UNDULATED SEA BEDS, INCLUDING AT GREAT DEPTH

摘要

ABSTRACT OF THE DISCLOSUREAn apparatus for supporting a pipe suspended over undulatedsea beds, including at great depth, comprising a supportmodule to be filled with liquid cement when positioned undersaid suspended pipe, and consisting of a high strength syntheticfibre fabric envelope of cushion configuration, with a rectangularbase piece joined at its edges to another saddle-shaped pieceacting as the top, and provided on one side with a hose fittedwith a non-return valve and with a connector for connecting toan instant connection and release coupling by means of aprojecting control lever, and which, strengthened and enclosed by atubular perimetral reinforcement, is releasably and rotatablysupported at a free end of a vertical articulated positioningarm constituted by three beam or trellis elements which, bymeans of horizontal pins, are hinged one after the other endrotatable one relative to the other about horizontal axes,the other free end of said vertical articulated positioningarm being rotatably hinged, by means of two horizontal rotationpins of which one is hollow for the passage of the liquid cement,2.on a vertical hollow pin supported rotatable through 360°about a vertical axis in a vertical tube portion weldedto the end of a bracket structure fixed to a recoverableservice module which is lowered by a depot ship on to thesea bed.Said vertical articulated positioning arm is also providedwith an articulated positioning arm is also providedjointed pipes, which follows the configuration of saidarticulated arm to which it is fixed and which connects saidhose of the support module to said horizontal hollow rotationpin connected by flexible conduits to the closure headpiecesis connected by flexible conduits to the closure headpiecesbeing of cone frustum shape and being clamped in a sealedmanner against the ends of the respective cylindrical containersby hydropneumatically controlled cams, and being all mountedon a single carriage which slides, under hydropneumaticcontrol, on two rails supported by said recoverable servicemodule.
