Abstract

Abstract

The foundation structure with piles and cap is one of the widely used structures for offshore wind farm construction in shallow water. The experimental studies on hydrodynamic loads acting on the piles and cap under irregular waves and currents were summarized with discussion about the pile group effect on wave forces and wave impact loads upon the cap locating near the free surface. Through theoretical solution of the wave diffracted by the cap and application of the Morison equation to evaluate the wave force on piles, the effects of the cap on wave force upon piles were investigated. Based on the RANS equations and the VOF method, a numerical wave basin was developed to simulate the wavestructure interaction. The computed maximum wave force on the foundation structure with piles and cap agreed well with the measured data. The violent deformation, breaking and runup of wave around the structure were provided and discussed. Further work on the turbulent flow structures and large deformation of the free surface due to interaction of waves and foundation structures of offshore wind farms is needed to develop efficient approaches for evaluating hydrodynamic loads under the waves and currents.
