Abstract

Offshore wind energy offers a huge potential for the expansion of renewable energies in Germany. High demands have to be made concerning foundation design and construction methods to find an economically and technically optimal solution. A promising foundation concept which can be used in this field is the monopile, which in principle is a prolongation of the tower shaft into the ground. The behaviour of large-diameter monopiles under the horizontal loading induced by wind and wave loads is analysed using a three-dimensional finite element model. Non-linear elastoplastic soil behaviour is taken into account. The results of the numerical simulations are presented and compared with the results of the p-y method commonly used for the design of laterally loaded piles.
