Performance-Based Design Optimization of a Transition Piece for Bucket Foundations for Offshore Wind Turbines

This paper deals with optimization of the shape of the transition piece connecting turbine column with a suction bucket used as a monopod foundation for an offshore wind turbine. The structural behaviour of a transition piece made of compact reinforced composite (CRC) is analysed. Several geometries are compared to find the one providing better force distribution, preventing stress concentration and buckling, reducing the amount of material used as well as potentially minimizing scour. Local optimization of the cross section is performed with the aim of minimizing the material consumption (steel, as well as CRC). A non-linear finiteelement model is developed for analysis of the structure
