Abstract
A marine compliant riser system connects a subsea hydrocarbon source to a floating surface facility through a lower multi-conduit riser section to a submerged buoy section located below a turbulent water zone and a flexible flowline. Fluid connection is established between corresponding lower riser conduits and the surface facility by a plurality of flexible conduits. Connection assembly means connects individual upwardly-directed flexible conduits with corresponding upwardly-directed lower riser conduits in fluid flow relationship. A yoke assembly mounted on the buoy section, includes beam means for holding a plurality of spaced apart flexible conduit terminations, with each of the flexible conduits being connected individually in catenary arrangement between the yoke assembly and the surface facility. The flexible conduits are attached to the surface facility in compact, non-linear array and to the yoke assembly in substantially linear array. A ribbon-like configuration is obtained by providing a plurality of spreader beams spaced longitudinally along the flexible flowline at predetermined locations, each of the spreader beams having annular conduit guide means mounted on the beam in laterally-spaced linear array for restraining the conduits from side movement while permitting longitudinal movement of individual conduits axially with the flowline.
