Monopiles are one of the preferred foundation technologies for use in offshore wind developments. During the lifetime of an offshore wind turbine, it is subjected to millions of lateral load cycles. Cyclic lateral loads may cause rotation and lateral deflection of the turbine structure which can lead to fatigue of mechanical components and a reduced lifetime. The displacement-rotation response of a monopile is a function of the soil properties, pile properties and the applied loads. However, the nature of the relationship between these factors is not well understood. The results of centrifuge testing on model monopiles subjected to a range of cyclic lateral loads are presented.
