Review of the Design and Research on Deepwater Steel Catenary Riser

With the development of offshore oil and gas exploitation,a steel catenary riser has become a widely used form of deep water riser.At present,it has been applied to a variety of offshore platform,such as TLP,semi-submersible platform and FPSO.Importance of the Steel Catenary Risers(SCR) in the development of offshore oil and gas is introduced in this paper. And analysis of the key influencing factors and main steps of steel catenary riser design are also presented in this paper.Then the main theories to analyse the SCR,including its static stress analysis and the movement equations,are introduced.Furthermore,main development and study during the past two decades are illustrated in this paper.Finally,problems faced in the design of SCR and its future development are forecasted,and corresponding suggestions are proposed.
