PISA: new design methods for offshore wind turbine monopiles

This paper provides a summary of the PIle Soil Analysis (PISA) project, completed in the UK during the period 2013 to 2018. The research led to the development of a new, computationally efficient, one dimensional design model for laterally loaded monopile foundations, particularly for offshore wind turbine support structures. The current form of the design model is applicable to monotonic loading only, but it could form a basis for extensions to cyclic loading. This short paper describes the background to the project, outlining the key research elements completed, as well as the main impacts that have been achieved. A number of publications describing the research in further detail are highlighted.
