The mechanism of vortex-induced vibration and vibration response of marine flexible risers were summarized from the aspects of theory,experiment,and numerical calculation.In terms of the basic characteristics of vortex-induced vibration of offshore flexible risers,the riser system of deepwater platforms,the main characteristics and influencing parameters of vortex-induced vibration were reviewed in detail.In terms of the research progress of vortex-induced vibration of marine flexible risers,the numerical analysis method and experimental analysis method of vortex-induced vibration were described in detail.In terms of the hot research issues of vortex-induced vibration of marine flexible risers,four major research hotspots were analyzed in detail as follows:the coupling of power equipment and underwater flexible risers,the coupling of particle flow in pipes and underwater flexible risers,the coupling between internal and external flow of marine flexible risers,and the suppression method and optimization scheme of vortex-induced vibration.Finally,based on the development trend of the research on vortex-induced vibration of marine flexible risers,it was pointed out that the combined action of wind and waves outside the risers,the motion of the upper floating body,the combined action of internal and external flows,and the coupling action of multiple risers were the future research and development directions.
