Abstract of the lecture:
An efficient source of renewable energy, which is increasingly the preferred solution for realising Britain’s short- and long-term energy ambitions, is offshore wind. The national target set by the UK government to increase the currently installed offshore wind capacity from approximately 10 GW to 50 GW in 2030 demonstrates the strategic importance of this clean source of energy in the UK’s energy mix. Fatigue and corrosion-fatigue interaction are the dominant material degradation mechanisms in Offshore Wind Turbine structures, particularly in the foundations which are in direct contact with seawater and subjected to cyclic loading condition. This means that during operation, fatigue cracks may initiate, in the presence or absence of corrosion pits, and propagate through the structure. Therefore, careful considerations must be made in the design and life assessment of these offshore structures by accounting for fatigue and corrosion-fatigue damage in the lifecycle analysis. The aim of this talk is to present the design and structural integrity challenges associated with Offshore Wind Turbines with the view to maximise the operational life, reduce the number of frequent inspections and deliver a direct beneficial impact on Operations and Maintenance (O&M) costs.
Bio of the speaker:
Prof. Ali Mehmanparast (PhD, MBA, CEng, CMgr) is a Professor of Structural Integrity at University of Strathclyde and the Manager of the Cranfield-Oxford-Strathclyde Universities Renewable Energy Marine Structures Centre for Doctoral Training (REMS CDT). Ali sits on the Engineering Integrity Society (EIS) Durability and Fatigue committee, the UK Forum for Engineering Structural Integrity (FESI Council) and is a member of the European Structural Integrity Society (ESIS). He is a Chartered Engineer of IMechE, fellow of The Higher Education Academy and fellow of the Chartered Management Institute. He has more than 100 peer reviewed journal and conference papers in the field of engineering structural integrity, and has organised and chaired technical sessions at international conferences. Ali was a member of the technical delivery team for the Structural Lifecycle Industry Collaboration (SLIC) Joint Industry Project, the PI of the Rutherford Appleton Laboratory funded project on welding residual stress effects on fatigue life assessment of monopiles, the academic lead of the Carbon Trust funded project on offshore wind turbine foundation flange study and the PI of research projects funded by the Supergen Wind Hub and Supergen ORE Hub on floating and fixed-bottom offshore wind turbine foundations.
