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.
