    • A marine riser system for transferring fluid between a well on the seafloor and a vessel floating on the surface of the sea. The riser system has a turret buoy capable of connecting to a floating vessel; two or more hybrid risers, each of the hybrid risers having a vertical riser, a riser buoy attached to the upper portion of the vertical riser and a flexible jumper connecting the riser buoy to the turret buoy, and wherein the hybrid risers are secured to the seafloor. A flowline may connect a lower portion of each of the vertical risers to a subsea manifold, which interconnects the flowline and a subsea well. The subsea manifold is capable of controlling the flow to or from a subsea well. The hybrid risers are positioned about the turret buoy so that the turret buoy is horizontally balanced while disconnected from a vessel. In another embodiment, the marine riser system is capable of directing a fluid from the floating vessel to a subsea export flowline. In another embodiment, the present invention discloses a method of producing hydrocarbons from a subsea well, utilizing the marine riser system.
    • 用于在海底井和浮在海面上的船舶之间输送流体的海洋立管系统。 提升管系统具有能够连接到浮动船的转塔浮标; 两个或更多个混合提升管,每个混合提升管具有垂直提升管,连接到垂直提升管的上部的提升管浮标和将提升板浮标连接到转台浮标的柔性跳线,并且其中混合提升板固定到 海底 流线可以将每个垂直立管的下部连接到海底歧管,其将流线和海底井相互连接。 海底歧管能够控制往返于海底井的流量。 混合式提升管围绕转塔浮标定位,使得转盘浮标在与容器断开的同时水平平衡。 在另一个实施例中,海洋立管系统能够将流体从浮动船舶引导到海底出口流线。 在另一个实施方案中,本发明公开了一种利用海洋立管系统从海底井生产烃的方法。
