    摘要： A hybrid riser system (10) for connection between a floating unit (12) and a sub-sea unit (14) that is located at the sea floor (18). The riser system (10) comprises a composite conduit (22) for transporting a fluid between said floating (12) and sub-sea units (14) and at least one end pipe section (20,24) that is adapted to be connected between the floating (12) and/or the subsea unit (14) and the composite conduit (22). Said at least one end pipe section (20,24) comprises a metallic pipe or a non-bonded flexible pipe.

    摘要： A flexible conduit formed by a helically wound band of metal that resists burst pressure. The band has a leading edge hook and a trailing edge hook that engage and interlock. The cross-section of the band has a radially asymmetrical Z-shaped profile. When the band is helically wound, the downstream hook of one turn of the band is received in the upstream valley of the previous turn of the band so that the downstream and upstream hooks form an interlock holding the windings together. In the wound configuration, the thickness of the profile between the upstream valley and the internal surface of the tube is greater than the thickness of the profile between the downstream valley and the external surface of the tube to provide greater material thickness to reduce contact stress at the hook and valley interface and to reduce alternating stresses in the valley corners. The outer surface of the profile tapers towards the center of the tube to direct externally applied radial compression forces toward the thickest section of the profile. A multilayer conduit employing the band may include a central, helically wound collapse-resistant layer disposed within a flexible fluid barrier that in turn is disposed within the tube formed by the band. The conduit may be wrapped with one or more tensile strength layers, anti-wear layers, and additional fluid barriers.

    摘要： A flexible conduit (10) constructed of overlapping layers of sealing and strengthening materials designed to resist tensile, compressive, and axial forces is employed as a submerged flow line carrying pressurized fluid. Sealing material layers disposed radially on either side of the strengthening layers isolate the strengthening layers from the liquids that contact the internal and external conduit walls. The innermost seal layer (12) is positioned within a burst layer that protects the external strengthening layers from pressure-induced damage. The annular area between the strengthening layers is continuously vented to the atmosphere to prevent pressure damage to the strengthening layers caused by gases leaking or permeating into the annular area through the seal layers. End connectors (25) join sections of the conduit (10) together and connect the vents of the sections to each other to form a continuous vent passage that vents the annulus gas at the water surface.
