Performance of Offshore Wind Turbine Under Expected Dynamic Environmental Loadings Considering Soil–Structure Interaction
摘要
Offshore wind energy is attracting global interest as a promising renewable energy source, with multi- megawatt offshore wind turbines (OWTs) being widely used to capture continuous wind energy. To ensure their optimal performance, it’s essential to analyze the dynamic responses of these turbines under realistic environmental conditions. Monopile foundations are commonly chosen for OWTs due to their simple construction, cost-effectiveness, and proven track record in offshore settings. The design of OWTs is determined by factors such as power output and environmental conditions, requiring careful sizing of components like the tower, monopile, and blades. This study provides a quantitative analysis of a 2 MW offshore wind turbine with a monopile foundation, assessing its performance under environmental loads like wind and wave forces. Using finite element analysis, the study checks the influence of loading parameters such as wind velocity, wave period, and wave height on the dynamic performance of the structure in terms of peak horizontal displacement and peak shear stress. Results indicate that the response of the OWT increases with increasing wind speeds and wave heights but decreases with longer wavelengths.
