| Abstract: | The critical positions prone to fatigue of hatch corners of ultra large container ship are illustrated, and the principle of the spectrum analysis method is discussed base on linear cumulative damage theory, and a reinforce method during the fatigue spectrum analysis are put forward. Several effective methods for extending the fatigue life of hatch corners are summarized in design stage and several common post processing methods are analyzed in manufacture stage. |
