Abstract: The invention relates to a device for transferring fluid between the sea bottom and the surface, especially for recovering and bringing up oil produced by an underwater formation, comprising at least one flexible tubular pipeline extending in a chain between a surface support and an intermediate member imparting to the pipeline, over some of its length, a curved configuration with a concavity facing the bottom, a part of the pipeline between said intermediate member and the sea bottom being tensioned and being fastened to the bottom at a fixed point. … It comprises means for retaining at least one zone of said lower part of the pipeline (3), which means are connected to the fixed point, consisting preferably of an anchorage (5), and which are designed to keep under tension the part (3b) of the pipeline located between the intermediate member (4) and the retaining means and to impart to the pipeline, in a vertical plane, a predetermined set curvature, the concavity of which is directed towards the structure, especially a wellhead (2), which is located on the sea bottom and from which the oil is to be brought up. … …

Abstract: PCT No. PCT/FR91/00264 Sec. 371 Date Jan. 29, 1992 Sec. 102(e) Date Jan. 29, 1992 PCT Filed Apr. 2, 1991 PCT Pub. No. WO91/15699 PCT Pub. Date Oct. 17, 1991.A device for laying flexible tubular conduits from a floating support comprises rigid accessories the outer diameter of which is greater than the outer diameter of the conduit. It comprises main, linear winch-type tensioning means (6) for normal lowering of the flexible conduit (3) to be laid. The linear winch has an essentially vertical axis and comprises the last means for guiding the flexible conduit at the level of the floating support (1) and auxiliary holding means (19) which hold the flexible conduit by means of an accessory (21) mounted on the flexible conduit, such as an end fitting or an auxiliary accessory, and enable the main tensioning means (6) to clear a section of flexible conduit on which the accessory (21) is mounted.

Date Mar. 4, 1999A 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.

Abstract: The invention concerns a spiral winder continuously producing a tubular structure consisting of a helical winding (2), in particular a pressure arch, from two non-self-clipping wires with thick cross-section supplied by two wire coils and two clipping wires supplied by two clipping wire coils. A powerdriven rotating circular frame (8) bears at the rear the four wire and clipping wire coils, while the frame (8) downstream surface carries on two trays (35) with adjustable inclination two incorporated double tracks (31, 31') for driving the wire (16) arranged just upstream of guide and/or bending rollers (34) driving the wires towards their respective twisting point (33).
