A steel catenary riser (16) is suspended from a floating platform (14) hanging in tension between seabed (12) and surface (10). A flexible conduit (18) extends between an upper end J of the steel riser and a fluid connection point F on the platform. An arm or tether 20 extends between the upper end (J) of the riser(s) and a hanging point (H) elsewhere on the vessel, typically midships. Most of the tension in the riser is carried by the tether, and the location of the hanging point is significantly closer to either or both the pitch and roll axes (R) of the vessel than it is to the fluid connection point. All fluid or mechanical connections can be made above the sea surface. |
