| Abstract: | The vortex-induced vibration(VIV) of span is one of the main factors resulting in fatigue failure of submarine pipe-lines.This paper described the reasons for the formation of free span.It summarized the calculation of the critical length on the free span,and discussed the theory of the vortex-induced vibration and experimental research in recent years.Finally,several suggestions on the free span research are provided. |
