Structural Optimization of Offshore Wind Turbine Foundations Under Dynamic Ocean Loads

Abstract

The increasing demand for renewable energy has accelerated the deployment of offshore wind turbines, requiring highly reliable and structurally efficient foundation systems capable of withstanding complex oceanic environments. This study investigates the structural optimization of offshore wind turbine foundations under dynamic ocean loads to improve stability, durability, and cost-effectiveness in offshore energy applications. The proposed research framework integrates finite element analysis, hydrodynamic load modeling, and optimization techniques to evaluate the structural behavior of monopile and jacket-type foundations subjected to wave, wind, and current-induced dynamic forces. A computational methodology was employed to analyze stress distribution, vibration response, fatigue performance, and displacement characteristics under varying environmental and operational conditions. Optimization algorithms were utilized to identify suitable geometric and material configurations that minimize structural weight while maintaining safety and performance requirements. Simulation results demonstrated that the optimized foundation designs significantly reduced stress concentration, structural deformation, and fatigue damage compared with conventional configurations. The findings also indicated improvements in load-bearing capacity, dynamic stability, and long-term operational reliability under severe ocean conditions. Furthermore, the optimized structural framework contributed to reduced material consumption and installation costs, enhancing the economic feasibility of offshore wind energy projects. The study concludes that advanced structural optimization techniques combined with dynamic load analysis provide an effective approach for designing resilient and sustainable offshore wind turbine foundations. The proposed methodology supports the development of high-performance renewable energy infrastructure capable of ensuring safe and efficient offshore wind power generation in challenging marine environments.
