Abstract

Here, effects of rigid body swing of steel catenary riser (SCR) on its transverse flow response was studied. The SCR response was solved with the finite element method considering large-deflection slender beam model, wave loading, top transverse motion input and rigid body swing model. Lissajous figures were used to realize verification of structural calculation. The calculation showed that the SCR response develops gradually from narrower range oscillation in YZ plane of the suspension point to a wider range ‘8’ shape oscillation in ZX plane of bottom touch point, the deeper the water depth, the smaller the response; the top region displacement response drops more sharply, while bottom region displacement response drops more slightly; rigid body swing effects reveals increase or decrease in amplitude, or even counterbalance, it is linearly related to radius vectors; effects of rigid body swing on SCR structural transverse displacement response can be estimated with a certain safe coefficient; the study results provides a reference for transverse flow response calculation of SCR.
