Abstract:

Topology optimization (TO) has experienced substantial progress in both scholarly research and practical engineering applications. Recent years have witnessed extensive research on TO approaches incorporating the failsafe concept, with a particular emphasis on potential failures. This paper proposes a TO methodology on the offshore wind turbine (OWT) jacket structure, focusing on the unexpected failure modes. The initial step involves constructing the formulation for maximum-minimization TO. A series of optimized structures can be generated by varying the sizes of individual damage populations and overall failure zones. A 5 MW OWT and jacket structure have been selected as the reference model. The external loads acting on the jacket structure are determined by given environmental conditions, as assessed using the DNV Bladed TM package. The feasibility of an optimized structure is evaluated by comparing its static behaviors, such as maximum displacement and von Mises stress, to those of the reference structure. The investigation focuses on the fundamental frequencies of the optimized structure under various damage populations. The discovery demonstrates the superiority of the suggested methodology in the case of a potential failure.
