This document addresses structural analysis procedures, design guidelines, component selection criteria, and typical designs for all new riser systems used on floating production systems (FPS). Guidance is also given for developing load information for the equipment attached to the ends of the risers. The recommended practice for structural design of risers is generally based on the principles of limiting stresses in the risers and related components under normal, extreme, and accidental conditions. This document assumes that the risers willbe made of steel or titanium pipe or unbonded flexible pipe. However, other materials can be shown to be fit for purpose. Design considerations for unbonded flexible pipe are included primarily by reference to API RP 17B and API Spec 17J.
