The accumulation of lateral displacement of monopiles under lateral cycling over the life of a wind turbine is a major design consideration. This paper presents the results from centrifuge tests on instrumented piles installed in kaolin prepared to an overconsolidation ratio of 2; the tests involved both monotonic loading and two separate one-way cyclic loading histories. It is shown that the geotechnical ultimate limit state is relatively un-affected by cycling but that large permanent rotations occur during cycling, even at a relatively modest cyclic load ratios.
