Dynamic analysis of marine structures in offshore wind farms using fluid-solid interaction models

Offshore wind farms (OWFs) have gained significant importance as a renewable energy source, especially in regions with abundant wind resources and available coastal areas. The structural integrity and durability of marine structures within OWFs, including turbines, foundations, and related infrastructure, are critical to their long-term performance and economic feasibility. This paper investigates the dynamic analysis of marine structures in offshore wind farms using fluid-solid interaction (FSI) models. FSI simulations provide a comprehensive approach to researching the interaction between the surrounding fluid (ocean water) and solid structures (wind turbines and foundations). These simulations incorporate the effects of hydrodynamic forces, wave loads, and environmental conditions, which are vital in ensuring the safety and resilience of marine structures. A detailed analysis of these interactions can optimize the design and enhance the operational efficiency of OWFs by reducing the risk of structural failure caused by dynamic forces. The research examines various FSI models, evaluates their accuracy, and assesses their ability to predict the behavior of marine structures under different operating conditions. The objective is to identify the most effective modeling approaches and to explore the impact of FSI on the design and maintenance strategies of offshore wind farms. Through numerical simulations, the paper explores factors such as wave-structure interaction, fluid flow patterns, and vibration frequencies that influence the performance of these structures. The results of this research contribute to a better understanding of the dynamic behavior of OWFs, providing insights for improving the design, maintenance, and operational planning of offshore wind energy systems.
