Abstract
In this paper the development of a monitoring system for hull fatigue of FPSOs is discussed. Fatigue assessment is subject to many uncertainties. Asset integrity can be improved by limiting these uncertainties. Continuous monitoring reduces these uncertainties, but requires extensive data analysis. Automated analyses are required to ensure the monitoring data is used in an optimal and consistent way. A joint effort of industrial partners has resulted in a smart data analysis system that shows fatigue accumulation in an easy-to-understand format. Sources of accelerated fatigue accumulation can be identified which enables rational actions to reduce lifetime consumption.
