| With the rapid advancement of offshore engineering, the long-term fatigue characteristics of structures have become a critical issue affecting the safe operation of ocean structures. Selecting appropriate and effective fatigue analysis methods for various types and functionalities of offshore structures under the influence of complex environmental loads remains a challenging issue in the academic realm. Therefore, this study reviews the evaluation methods for fatigue damage of offshore structures including the calculation principles of external environmental loads such as wind and waves acting on offshore structures, random load processing methods. Subsequently, a review of fatigue analysis methods based on S-N curves and crack propagation is provided, including linear and nonlinear damage accumulation theories. Finally, the entire fatigue damage evaluation process is demonstrated through engineering examples. This study provides a valuable reference for selecting fatigue analysis methods in the ocean engineering field, enhances the understanding of the practical value of fatigue evaluation methods in ocean engineering, and facilitates further exploration of how to improve the safety and reliability of ocean structures through fatigue evaluation. |
