• The marine riser is an important part connecting the undersea drilling and the offshore platform. The primary factor causing the fatigue damage of marine risers is the vortex-induced vibration. Due to the random effects of ocean currents, the vortex-induced vibration of the riser is uncertain. Quick and reliable analysis of such random vibration is of great importance for the engineering design of the riser. Compared with the deterministic excitation, the random excitation is much more difficult to analyze, and the pseudo-excitation method is an efficient tool for this problem. In recent years, the pseudo-excitation method was applied and extended by the author and his collaborators for the analysis of vortex-induced vibration of marine risers, and many achievements were made, which were briefly summarized.
