ABSTRACT
This chapter explores a procedure to generate the fatigue load history based on a Storm Model. An application example is given to demonstrate the fatigue life prediction for a tubular T-joint of an offshore platform by using the generated load history, which shows the practical and effective use of the proposed procedure. In order to apply the Fatigue Crack Propagation-based approaches in the design of marine structures, fatigue load needs to be provided as the load-time history in the time domain rather than the used load spectrum in the frequency domain. Japanese researchers presented another relatively simple load sequence generation model called storm model. The chapter presents an improved procedure to generate fatigue load history by using seasonal Wave Scatter Diagrams (WSD) instead of the averaged one that was used before. This implies the use of separate WSDs for each of the seasons.
