Vortex-Induced Vibration of a Vertical Riser
Vortex-induced vibration (VIV) often causes the fatigue of offshore slender structures, such as risers, mooring lines and pipelines. Detailed understanding of this fluid-structure interaction (FSI) phenomenon and an efficient prediction of such self-excited and self-sustained oscillations are required for the reliable estimation of the fatigue damage and the development of VIV suppression techniques. In this study, VIV of a vertical riser in uniform and linearly sheared currents is studied. The main objective of this study is to address the importance of the IL fatigue damage.
