A study was conducted on the initial stages of floating wind turbines design, which face significant challenges. The research focused on the comprehensive investigation of the aerodynamics of wind turbines, hydrodynamics of floating platforms, and dynamics of mooring lines. The study also examined the interaction between these components and their effects on each other. The research introduced a new design for the heave plate, optimizing its dimensions for supporting a 5-MW wind turbine in deep offshore waters near Jask Port in the Oman Sea. Through numerical simulations, the study evaluated the coupled dynamic responses of the floating wind turbine system to wave loads, currents, tides, and winds. The findings demonstrated that the optimized heave plate effectively met operational requirements under normal and severe conditions. Additionally, the study highlighted the superior performance of the optimized heave plate in the structural-wave interaction, providing satisfactory results.
