Meeting The Challenge of Fatigue Design for Offshore Structures

The energy sector has been building offshore structures for many decades. What started in the 1880s with wooden piers and towers in the shallow waters off California has transformed into the deep-water engineering feats we see today. What was clear from the beginning was the importance of fatigue as a life-limiting failure mode for offshore structures. Today, as we move into harsher environments including deeper water and wilder weather to maximise the potential of our available energy resources, our understanding of fatigue in offshore structures has never been so important. Indeed, the wealth of experience of designing offshore structures for the Oil & Gas industry, that can withstand challenging conditions for fatigue design, is now being transferred to enable realisation of the vast potential for renewable energy that can be harnessed offshore, including fixed and floating offshore wind. In this talk, James will provide an overview of the engineering challenges associated with fatigue in offshore structures. This will include some examples of the challenges faced from different modes of fatigue, and the advances being made to meet these challenges. For example, how do you account for dynamic loading imposed on topside pipework by waves impacting the conductor? And, how can advanced probabilistic techniques combine with classical fracture mechanics to improve the calculated fatigue life of your offshore wind turbine?
