Abstract
Abstract The steel catenary riser (SCR) is the preferred riser solution for the cost‐effective development of deepwater fields and has been successfully adapted to a variety of floaters including spars, tension leg platforms (TLPs), semi‐submersibles, and floating production storage and offloading vessels (FPSOs). This article presents an overview of the design, fabrication, installation, commissioning, and operational aspects of SCRs. The American Petroleum Institute has issued a new riser code “Dynamic Risers for Floating Production Systems API Standard 2RD, Second Edition”. This article summarizes four design methods. SCR design is often driven by the fatigue damage considerations at the floater hang‐off location and the touchdown zone (TDZ). The fatigue at the hand‐off region can be mitigated using specialty joints such as flex joint and stress joint. TDZ fatigue is more complicated due to uncertainty associated with pipe–soil interaction process. Finally, installation using different pipe‐laying methods such as S‐lay, J‐lay, and reeling are discussed.
