Job description

The post-doctoral researcher will advance the knowledge of cyclic soil-monopile interaction in offshore wind turbines using state-of-the-art numerical modelling. Scientific challenges exist in the fundamental understanding and conceptualisation of cyclic pile behaviour, and its translation into engineering models (e.g., based on the well-known p-y approach).
The researcher will numerically investigate the cyclic behaviour of laterally loaded monopiles in sandy soil, under a variety of loading and geotechnical conditions. The work will include development, set-up and calibration of 3D FE monopile models, in combination with advanced constitutive modelling of cyclic sand behaviour. Design of the numerical simulation programme, and validation of obtained results, will be carried out in close collaboration with experimentalists and industry experts involved in the research project. The new knowledge gained from combined physical and numerical modelling will be oriented towards the formulation and implementation of a new engineering p-y model for the analysis of large-diameter monopiles in sand under cyclic loading.
This position is supported by MIDAS (Monopile Improved Design through Advanced cyclic Soil modelling), a research project funded by the Netherlands Enterprise Agency (Rijksdienst voor Ondernemend Nederland - RVO) and industry partners in the framework of the Dutch offshore wind program GROW. TU Delft is the leading institution of a team including Deltares, Eneco, IHC, Innogy, Shell, Siemens Gamesa Renewable Energy, and Van Oord.
