  • Connector for steel catenary riser to flexible line without stress-joint or flex-joint
    Patent number: 9074428
    Abstract: A flexible element in a basket-like structure supports a Steel Catenary Riser (SCR) on a subsurface buoy or “artificial seabed.” A riser collar transfers the tension load of riser to a compressive load on the radial bearing. Relative motion between the subsurface buoy and the riser is accommodated by the flexible element. A flexible jumper is connected to the riser for fluid transfer. Motions of the riser relative to the subsurface buoy are accommodated by the flexible jumper. In this way, a transition from an SCR to a flexible jumper may be accomplished without the need for either a stress-joint or a flex-joint.

  • Buoy-to-riser connector
    Patent number: 8282433
    Abstract: A support for a subsea riser decouples the function of the riser into two separate functions: the load transfer function which supports the hung weight of a subsea riser configuration to a supporting floater (such as the buoy of a disconnectable fluid transfer system) and the fluid transfer function which provides a continuous flow path for the fluid coming to or from the riser.
