Structural Integrity Assessment of Offshore Wind Turbine Foundations

7th February 2020, Brussels, Belgium

Given the harsh environment of offshore wind, a major design and O&M challenge is the corrosion and fatigue of the structure. This workshop is designed to give engineers a more rounded appreciation of the unique considerations that should be given to the structural integrity assessment of offshore wind turbine foundations

 

Several areas will be covered leaving delegates with a more rounded appreciation of the fatigue issues relevant to offshore wind foundations. Throughout the course, tutorials and practical considerations will be used to consolidate the knowledge gained by the attendees and gauge their understanding.

About the Lecturer

Dr Ali Mehmanparast is a Lecturer in Structural Integrity at Cranfield University and the Manager of the Cranfield-Oxford University Renewable Energy Marine Structures Centre for Doctoral Training (REMS CDT). Ali currently 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 and a fellow of The Higher Education Academy. He has more than 50 peer reviewed journal and conference papers in the field of engineering structural integrity and has chaired technical sessions at international conferences. He was also a member of the local technical committee for “Fatigue 2017” International Conference in Cambridge. Ali is the manager of the Structural Integrity Laboratory at Cranfield University and a member of the technical delivery team for the Structural Lifecycle Industry Collaboration (SLIC) Joint Industry Project, which is a collaboration between 10 Offshore Wind Operators, the UK Department for Energy and Climate Change and The Crown Estate to improve the structural design and integrity of offshore wind monopiles. He is currently the PI for a project funded by Rutherford Appleton Laboratory to investigate the welding residual stress effects on structural integrity of offshore wind turbine monopiles. He is also the academic lead of a project funded by The Welding Institute (TWI), Lloyd’s register and EPSRC to assess the crack arrest behaviour in modern structural steels. Ali is the Cranfield PI of the Cranfield-LICenergy joint project on offshore wind turbine foundation flange study. Moreover, he is the PI of the Cranfield-Imperial EPSRC-SUPERGEN Wind Hub funded project on offshore floating wind turbine structures.
