Abstract

To enhance the reliability of offshore wind turbine jacket structures under unexpected scenarios such as deformation or even fracture caused by ship collisions, this paper proposes a fail-safe based topology optimization (TO) method for the jacket structures. The maximum-minimization TO formulation is constructed. By varying the size of individual failure zone and overall zone size, a series of optimized structures are obtained through optimization solutions. Taking the TO results under a certain weighting factor as an example, the ultimate loads are calculated based on the IEC 61400-3 principle, and the response of the jacket under ultimate load conditions are analyzed using the finite element method. The focus is on examining the first-order natural frequency of the complete offshore wind turbine and the maximum deformation of the jacket for different structural designs. The results indicate that the optimized structures exhibit superior performance under potential failure conditions, thereby validating the feasibility and superiority of the proposed method.
