Multi-body dynamic analysis of offshore wind turbine considering soil-structure interaction for fatigue design of monopile
Abstract Fatigue design of monopile foundation for an offshore wind turbine using multi-body dynamic analysis is the theme of this paper. For this purpose, a benchmark turbine is modelled in Kane's approach considering soil-structure interaction for a site at the North Sea. Each soil layer is modelled using the p-y curve, and the dynamic response of the combined system is simulated using aero-hydro-servo-elastic analysis. The fatigue life is estimated following IEC 61400-3 guidelines. The numerical analysis presented in this study shows stress-based fatigue analysis using rainflow algorithm in the light of soil-structure interaction for short-term damage accumulation. Besides short-term effects, the study also investigates serviceability criteria over the lifespan of the structure, i.e. long-term effects. Finally, design curves are developed for a given power rating. Overall, the study highlights the importance of soil-structure interaction and its impact on the fatigue life of offshore wind turbines.
Highlights Multi-body dynamics of the offshore wind turbine is modelled using Kane's approach. Fatigue design is carried out considering soil-structure interaction and rotor dynamics. Long-term performance of the monopile is investigated in terms of characteristics strain. Site-specific design curves are generated for the design of monopole in different flow conditions.
