Abstract
This paper presents an investigation on the interaction between extreme waves and monopile support structures. A time-domain nonlinear potential flow model is developed based on the weak-scatterer approximation. On the free surface, the 4th-order Runge-Kutta scheme with an arbitrary Lagrangian-Eulerian (ALE) approach is adopted in the time marching process. The corresponding boundary value problem is solved by the higher-order boundary element method (HOBEM) at each time step. A comparative study has been performed to investigate the interaction of steep focused wave groups with a fixed vertical cylinder. The present numerical results of wave elevations and dynamic pressures recorded at different positions are provided and compared with the experimental data. Then the wave run-up and inline force are analysed in the time-frequency domain based on wavelet transforms.
