| Abstract: | Fatigue assessment methods of "ship" ocean engineering structure were discussed in detail. Combined with finite element method, adapted a simplified and practical engineering method to conduct fatigue analysis. Calculated the fatigue cumulative damage and fatigue life of a Topside pipe rack, and this verified the rationality of the structure fatigue resistant design. The fatigue analysis process is simple and feasible, and it can provide a reference for the fatigue life assessment of similar engineering structures. |
