SS09: Offshore Foundations

Summary: Offshore wind turbines are typically placed on monopiles, but many other concepts (including gravity-based footings, jacket structures and bucket foundations) have been proposed. To understand fully the behaviour of the foundations, including their interaction with the surroundings, sophisticated models are required. However, for design purposes, simplified approaches are also of high interest, and the models should be validated experimentally by comparison with laboratory or prototype tests. The mini-symposium focusses on development and application of computational models for offshore foundations with regard to static, cyclic and dynamic analyses. The models can be analytical, semi-analytical or numerical; they can be based on system–reduction techniques or macro-element formulations. Papers addressing experimental validation of such models are also welcome. Relevant topics include load estimation, structure, structure–soil–fluid interaction, constitutive modelling of soil and foundation materials as well as modelling of soil–structure interfaces. Applications will include foundation installation, geotechnical and structural failure, deformations, fatigue, buckling and other instability issues, scour, deterministic and stochastic analyses, design standards, feasibility studies, novel foundation concepts or case studies.
