Abstract

Foundations are ~25% of offshore wind deployment costs, and therefore, industry could benefit from technological improvements that would make developments more economical. Suction bucket jackets are advantageous due to the fast installation process. However, uncertainties regarding the suction bucket load-sharing mechanism and the response in more complex stratigraphies remains. Furthermore, there is a need to advance modelling techniques tailored to offshore wind loading conditions. In this thesis, experimental modelling is used to address uncertainties regarding the response in the absence of lid invert-soil contact and in layered stratigraphies, while numerical and statistical learning techniques are used to enhance modelling capabilities.
