PICASO: Cyclic loading of wind turbine monopiles
The PICASO project is a multi-faceted collaborative project between the University of Oxford and Ørsted that aims to develop the next generation of cyclic loading models for offshore wind turbine monopiles. The project focuses on a wide range of activities including (a) detailed development of PISA type 1D finite element models, including the application of machine learning techniques for model calibration, (b) completion of laboratory element and laboratory model testing in a wide range of soils, including monotonic and cyclic loading, (c) development of new theoretical methods to capture cyclic loading within a plasticity framework (HARM), such that it can be adapted to 0D, 1D and 3D type modelling of foundations, (d) field scale testing at a clay and sand site, adopting realistic loading patterns for cyclic loading, and exploring rate effects, at two different pile diameters (1.22 m and 2.5 m), (e) translation of the research findings to design applications. This paper provides an overview of the research completed and the important findings for design practice.
