FATIGUE ANALYSIS FOR DEEPWATER FIXED-BOTTOM PLATFORMS

As the offshore oil industry moves into deeper water, fixed-bottom platforms will be found to exhibit dynamic amplification of wave-induced response. The resulting dynamic loads will have a significant effect on the cyclic stresses used in a fatigue analysis. State-of-the-art fatigue analyses require some sort of stress-history curve, which is extracted from the dynamic response indicated by a mathematical model of a platform. The mathematical model of the platform is subjected to finite length synthetic wave profiles representing operational and severe sea states for a given location.
