Abstract: Offshore wind power stands as a prime exemplar of high-end technological innovation in the renewable energy sector and is poised to be one of the high-growth industries of the future. In this study, a static mechanics and fatigue characteristic curve approach was utilized, employing both Abaqus and Fe-safe for the simulation analysis of the braced foundation transition sections in an offshore wind farm project in Shantou, Guangdong. The analysis revealed vulnerabilities in the stiffener plates and base plates of the transition sections. By increasing the thickness of the stiffener plates and adding sub-beams to the base plates, the structural stress was effectively reduced by 10–50%, thus ensuring the safety and suitability of the turbines. This provides a reference for the design of similar engineering transition sections.
