OPUS4-39585 Vorlesung Cuéllar, Pablo Deep foundations for offshore wind turbines In this lecture, both the physical behaviour and the general design procedures for deep foundations in the context of the offshore wind energy generation are presented. The first part of the lecture deals with the phenomenology and design of the pile foundations relative to the bearing of axial loads. The second part dwelves on the particularities of the lateral loads as well as on two research topics beyond the current design procedures, namely the hydromechanical coupling and the aging and fatigue phenomena as observed in the course of large-scale field tests. 7 Bauwerkssicherheit
OPUS4-44764 Vorlesung Cuéllar, Pablo Deep foundations for offshore wind turbines This presentation deals with the phenomenology and design of pile foundations for offshore wind turbines, and is divided in two lectures. The first lecture presents a brief introduction to the context and peculiarities of such foundations, and then focuses on the particular case of axially loaded piles. This part is most relevant for the relatively slender piles of the multi-pile substructures (i.e. jackets and tripods). A clear distinction between physical phenomenology and practical design is drawn here. The second lecture continues with the case of lateraly loaded offshore piles, which bears most relevance for the case of the monopile foundations. Here again, a clear separation between physical reality and design methods is intended. Finally, the last part of the second lecture introduces several advanced topics which lie outside the classical design approaches, namely the cyclic pile fatigue and the so-called pile setup (i.e. the time effects on the axial pile capacity). The relevance of these two topics is illustrated with experimental results from a field testing campaign on real large-scale piles. 7 Bauwerkssicherheit
