“…7(b), the research concluded that the forced vibration can be used to map the hydrodynamic properties of WIV, and hence predict the dynamic response of WIV. In addition to predicting WIV from hydrodynamic analysis, Song et al [82] established an empirical model for the prediction of WIV frequency response based on a fitted Strouhal frequency formula. Nevertheless, a further conclusion from these works is that the understanding of the flows and responses of WIV presents a continuing challenge and there may be yet more modes of shedding and mechanisms of response to be uncovered.…”

As a fundamental fluid-structure interaction (FSI) phenomenon, vortex-induced vibrations (VIVs) of circular cylinders have been the center of the FSI research in the past several decades. Apart from its scientific significance in rich physics, VIVs are paid great attentions by offshore engineers, as they are encountered in many ocean engineering applications. Recently, with the development of research and application, wake-induced vibration (WIV) for multiple cylinders and galloping for VIV suppression attachments are attracting a growing research interest. All these phenomena are connected with the flow-induced vibration (FIV). In this paper, we review and give some discussions on the FIV of offshore circular cylinders, including the research progress on the basic VIV mechanism of an isolated rigid or flexible cylinder, interference of multiple cylinders concerning WIV of multiple cylinders, practical VIV suppression and unwanted galloping for cylinder of attachments. Finally, we draw concluding remarks, give some comments and propose future research prospects, especially on the major challenges as well as potentials in the offline/online modelling and prediction of real-scale offshore structures with high-fidelity CFD methods, new experimental facilities and applications of artificial intelligence tools.
