Scour effects on the dynamic behavior of monopile-supported offshore wind turbine
Scour effects on the dynamic behavior of monopile-supported offshore wind turbine
In recent years, offshore wind turbines have seen increased development worldwide to harness wind energy in coastal regions. The monopile foundation is the most widely used foundation for offshore wind turbines, selected based on met-ocean conditions. This research primarily examines the impact of scour on the natural frequency of offshore wind turbines (OWT) through free vibration analysis. The study investigates the effects of varying scour depths and types on the structural behavior of monopile foundations through a series of finite element simulations. The design of monopile foundations and soil has been considered as per the feasibility studies conducted on the locations that are the potential offshore sites for the upcoming offshore wind farms in India. It aims to determine the influence of different scour types on the natural frequency of offshore wind turbines, considering the reduction in stiffness due to the removal of soil around the monopile foundation.
