    • The present invention discloses multiple sealing systems for composite risers and methods of preventing interior fluid leakage to the outside of composite risers. Single or multiple elastomeric seals are formed between an elastomer applied in single or multiple grooves provided circumferentially along the outer surface of a metal to composite interface (MCI) of a liner assembly of the composite riser and an elastomeric shear ply provided on the outside of the liner assembly. The elastomeric seals and a seal between the MCI and the liner of the liner assembly provide a multiple sealing system for the composite riser to prevent leakage of interior fluids. In the event that the integrity of the seal between the MCI and liner fails or the integrity of the liner is compromised, the elastomeric seals would prevent leakage of the fluid to the outside of the composite riser.
    • 本发明公开了用于复合提升管的多个密封系统和防止内部流体泄漏到复合提升管外部的方法。 单个或多个弹性体密封件形成在施加在单个或多个凹槽中的弹性体之间,该凹槽沿复合提升管的衬套组件的金属与复合界面(MCI)的外表面周向设置,弹性体剪切层设置在 内胆组装。 弹性体密封件和MCI和衬套组件的衬套之间的密封为复合提升管提供了多个密封系统,以防止内部流体泄漏。 在MCI和衬管之间的密封的完整性损坏或衬套的完整性受损的情况下,弹性体密封将防止流体泄漏到复合提升管的外部。

    • A method of manufacturing a composite riser section with a liner assembly comprises holding the liner assembly in a horizontal position, bowing the liner assembly upward, and winding resin impregnated fibers about the liner assembly to form a structural composite overwrap. Another method of manufacturing a composite riser with a liner assembly comprises holding the liner assembly in a horizontal position between two supports, and winding resin impregnated fibers about the liner assembly to form a structural composite overwrap. A system for manufacturing a composite riser section with a liner assembly having a longitudinal axis comprises a first support and a second support that hold the liner assembly in a horizontal position therebetween, and a plurality of rollers that rotate the liner assembly about the longitudinal axis.
    • 一种制造具有衬套组件的复合提升部分的方法包括将衬套组件保持在水平位置,向上弯曲衬套组件,并将树脂浸渍的纤维缠绕在衬套组件上以形成结构复合外包装。 制造具有衬套组件的复合提升管的另一种方法包括将衬套组件保持在两个支撑件之间的水平位置,以及围绕衬套组件卷绕树脂浸渍的纤维以形成结构复合外包装。 用于制造具有纵向轴线的衬套组件的复合提升部分的系统包括第一支撑件和将衬套组件保持在水平位置之间的第二支撑件以及使衬套组件围绕纵向轴线旋转的多个辊子。
