“…Klaycham et al [5] derived the motion equation of a large-displacement deepwater riser based on the Hamilton variational principle and studied the nonlinear-free vibration characteristics of the marine riser. By the Galerkin method, Zhou et al [6] conducted research on the effects of the elastic constraints simulating damaged and undamaged boundaries on the natural frequencies and shapes of marine risers with a variable axial tension. Alfosail et al [7] studied natural frequencies and mode shapes of the linear vibrations of inclined risers and proposed a numerical state-space approach to examine the natural frequencies and critical buckling limits of the marine riser [8].…”

Marine riser is a key equipment in offshore drilling operation, and failure of the riser can lead to drilling moratorium; in severe cases, it may cause oil and gas leaks. In this paper, the time-dependent boundary conditions of the riser and the randomness of wave load are considered to improve the calculation efficiency and accuracy of the dynamic response of the jack-up riser. Based on the Euler–Bernoulli beam theory, an analytical method to determine the response of the jack-up riser subjected to the random wave load was established by the Mindlin–Goodman method in the frequency domain, and an experiment was carried out to verify it. The research shows that transverse dynamic response is the main component of the transverse response of the riser, and the method proposed is feasible to calculate the transverse response of the riser.
