    摘要: A method for laying a pipeline formed of joined rigid and flexible tubular conduits on an underwater surface, particularly an ocean bed, by using a floating support. The method includes the steps of: loading onto the floating support a length of flexible tubular conduit; laying from the support a length of rigid tubular conduit; connecting the ends of the two conduits together; lowering the conduits; and halting the lowering when the rigid conduit hits bottom, while the other end of the flexible conduit is still in the floating support.

    摘要: A device for laying flexible tubular conduits from a floating support is provided. The flexible tubular conduit has insulating sheaths and reinforcements where the conduit includes a recoverable flexible tubular handling conduit connected to the flexible tubular conduit. The flexible tubular handling conduit has sufficient mechanical strength to withstand the combined action of the highest internal pressure and the axial tensile force corresponding to the apparent weight in water of the length of tubular handling conduit which is suspended between the floating support and the floor, and on the other hand, the isolated action of the axial tensile force corresponding to the apparent weight in water of the length of flexible tubular conduit when the latter is suspended between the floating support and the floor by the flexible tubular handling conduit.

    摘要: A wire-spiralling machine continuously produces a tubular structure comprising a spiral winding, particularly a pressure-armor layer, from two noninterlocking wires of large cross section delivered from two reels of wire and two locking wires delivered from two reels of locking wire. A motorized rotating circular cage carries the four reels of wire and locking wire at its rear, while the downstream face of the cage supports, on two adjustable-inclination plates, two on-board twin-track caterpillars for dragging the wire. These caterpillars are arranged just upstream of guide and/or bend rolls leading the wires towards their respective lay point.

    摘要: A device for temporarily holding a load on a vertical holding line including two articulated elements forming a pincer, each element having a jaw and an arm, one of the two arms including a connection for fastening to a holding line, the device being able to assume two positions, a first closed position for gripping the held load and a second open position enabling the load to be released; the arm having the ability to intensify the gripping force f which is exerted between the two arms near their end, in order to keep the jaws closed when the load is being gripped. The device further includes a feature for limiting the separation connecting the arms by exerting the gripping force f necessary for maintaining the first closed position of the jaws, the arms having a configuration such that the cable, or the like, for limiting the separation of the lever arms is placed laterally at a distance greater than 3.0 meters relative to the axis of the holding line.

    摘要: A transferring sea buoy is moored to the sea floor via an anchoring line. The anchoring line comprises a chain and an anchoring device for fastening the chain and the buoy. The anchoring device comprises a deformable longitudinal element having a first end connected to the transferring sea buoy and a second end connected to the chain. The deformable longitudinal element is deformable when the transferring sea buoy moves. The member has at least first and second portion of thin rectangular cross-section, each deformable in one plane to absorb relative motion between the buoy and the chain.
