    摘要： The present invention relates to a piece of seabed-to-surface linking equipment between a plurality of submarine pipes (3) resting on the seabed (12) and a support (1) floating on the surface (10) and anchored (1a) to the seabed, including: a) a so-called floating support including a turret (2), and b) a plurality of flexible pipes (7, 7a-7b) extending from said turret to a respective plurality of rigid pipes (4a), said rigid pipes (4a) providing the link between said flexible pipes (7, 7a, 7b) and said respective plurality of submarine pipes (3) resting on the seabed, said equipment being characterised in that it includes a guide structure (5) held under the surface (H l) between said turret (2) and the top of said rigid pipes (4a), said guide structure (5) being suitable for guiding said flexible pipes (7), said guide structure (5) including a plurality of first guide elements (5b) respectively crossed by said plurality of flexible pipes, such that one such flexible pipe includes at least one lower flexible pipe portion (7-1) in catenary curve configuration, and a second flexible pipe portion (7-2) extending entirely above the contact point (5b1) between the flexible pipe and said first curve guide element (5b) forming a chain from said guide element (5b) which said flexible pipe crosses in the direction of said turret (2) to which the top end of the latter (7-2') is connected.

    摘要： The invention concerns a cylindrical connector (1) designed to connect two elements (2) of a set of at least two axial pipes, comprising an outer pipe (21) containing an inner pipe (22) delimiting an annular space (23) containing preferably an insulating material (24). The invention is characterized in that the stamped connector forms two annular cavities (4) and (6) delimited by forking branches at each end of said connector which enable the stresses and strains to be reduced to a minimum at the connecting zones between the two connectors at the end of two lengths of coaxial pipes to be connected and between each pipe length and each connector at their ends.

    摘要： The invention concerns a single-unit element of underwater pipe for a seafloor-surface connection, consisting of an assembly of two coaxial PiP-type pipes (1) comprising an inner pipe element (2) and an outer pipe element (3) with an annular space (4i) therebetween, preferably including a thermal insulation material (42) in said annular space and including at each end a steel-forged junction piece (6, 6a-6b) for connecting said two single-unit elements of coaxial pipes (1), said junction pieces (6) being welded both at the ends of said inner pipes and at the ends of said outer pipes. The invention is characterized in that said inner pipe element (2) comprises in its main part an inner metal tube (20) with reduced thickness relative to the thickness of the ends of said inner pipe welded to said junction pieces (6), the inner tube (2) being coated with a material (22) comprising longitudinal continuous fibers wound about said inner tube so as to completely cover the surface of said inner tube.

    摘要： The invention relates to a device for heating and thermally insulating at least one main undersea pipeline (1a) for the circulation of a warm flow comprising a heat insulation coating (2) which wraps one or several main pipelines (1a) and is covered with an external waterproof jacket (3) and an internal chamber (4) which is coaxially arranged with respect to said jacket (3). The insulating coating wraps the internal chamber (4) in the annular space between said external jacket (3) and the internal chamber (4). The main pipeline (1a) extends inside the internal chamber (4) which is embodied, preferably, in the form of a cylinder. The inventive device also comprises means (61) for maintaining the temperature of a liquid coolant (5) and for circulating said coolant inside the internal chamber in such a way that the main pipeline (1a) which is arranged in the chamber (4) is surrounded by the coolant (5).
