Stability and Frequency Response of Top-Tensioned Risers and SCR’s: The L/D Ratio in Perspective

Abstract: Stability is closely linked to the dynamic behavior of risers and SCR’s. This paper reviews the L/D criterion as used to categorize offshore structural elements and places this criterion in perspective when used in VIV calculations to compare slender beams, beam-columns and cable behavior to anticipated results for top-tensioned risers with like L/D ratios. The stability of beam-columns with various end conditions and loadings are compared to that of an in-service 2400m top-tensioned riser. An analytic solutio… Show more
