Abstract

© 2019 Elsevier Ltd Marine risers are subject to vortex-induced vibration (VIV) caused by a combination of various external and internal excitations. The external excitations include the current-induced hydrodynamic forces and the wave-induced motions of the floating platform, while the internal excitation refers to the effect of internal flow. With significant increase of the riser aspect ratio, the VIV becomes much more complicated, resulting in more frequent fatigue damages to the risers. Hence, VIV is an important research area in marine engineering. This review surveys the latest progress on the VIV research, including the multi-mode response, VIV response at high Reynolds numbers, flow-induced vibrations between multiple marine risers, VIV of inclined risers and intermittent VIV in oscillatory flow. Particularly, the impacts of the floating platform and internal flow that have not been widely considered in previous studies are discussed to comprehensively understand the VIV of marine risers. Moreover, typical experimental and numerical investigations on the VIV of marine risers are also introduced.
