There is currently a significant focus on developing offshore wind power in the UK and Europe.The most common foundation type for wind turbines is a single large diameter pile, termed a monopile, onwhich the turbine is located. As the diameter of such piles is envisaged to increase in future installations, thereare concerns that current design methods are not applicable. To explore this problem, the joint industry projectPISA has been established, with the aim to develop a new design framework for laterally loaded piles utilised inthe offshore wind industry, based on new theoretical developments, numerical modelling and large scale fieldpile testing. This paper presents an overview of numerical modelling undertaken as part of the project.
