The search for more sustainable energy sources to replace fossil fuels has encouraged the development of several energy sectors, including floating offshore wind energy. Growth in this area focuses on research in platforms for aero-hydro-servo-elastic codes such as OpenFAST and aero-hydro coupling methods. In this thesis, the innovative floating platform, which was previously designed for 300 kW and 5 MW capacities, has been modified in terms of dimensions and features to be suitable for analysis with the 5 MW NREL reference wind turbine. The study examined coupling methods for spar, semisubmersible, common in the literature, and innovative platforms. This involved determining natural periods and damping ratios to see the system responses and behaviors of turbines and platforms, free decay tests, and various loads, including steady and turbulent wind conditions in regular, irregular wave conditions. The analysis provided several conclusions, including the verification of coupling methods, comparative evaluations of different platforms, and investigations into the behaviors of the innovative platform under flexible and rigid configurations. In this context, open-source programs like Capytaine and NEMOH and the commercial program AQWA produce results similar to WAMIT’s OpenFAST outputs. The F2A coupled method also shows strong correlation and consistency with these results. Furthermore, while the innovative platform with mooring lines achieves higher values than other platforms, its pitch angle is significantly lower, which is crucial for system stability, fatigue, and extreme loads. This reduces loading on components such as the tower blade and yaw bearing
