<p>In recent years, offshore wind turbines have seen increased development worldwide to harness wind energy in coastal regions. Offshore sites in the Gujarat coastal region, a potential location for upcoming offshore wind farms, are subjected to critical and harsh environmental conditions. Therefore, extensive research is necessary to properly assess the associated risk. The current study addresses one aspect concerning the scour development around the offshore wind turbine (OWT) foundations. Based on sediment inspections at Gujarat’s coastal locations, the site is highly susceptible to scour, which can weaken the strength and stiffness of OWT structure’s foundations. Therefore, a comprehensive study is essential to understand these geohazard’s effects better and potentially reduce the LCOE for modern clean energy technologies. The monopile foundation is suggested for these offshore wind turbines, selected based on met-ocean conditions. This research primarily examines the impact of scour on the dynamic behavior of OWTs supported on the monopile foundation. The present study focuses on assessing the deformation behavior and natural frequency of these monopile-supported OWTs with different scour geometries. The free vibration analysis method is utilized to evaluate the natural frequency of OWTs. The OWT is subjected to free harmonic motion considering the embedment of the monopile in a continuum medium. It 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 per the feasibility studies conducted on the sites. The study highlights the significance of the scour consideration while assessing the dynamic behavior of the monopile foundation.</p>
