Large scale Offshore Wind Farms has emerged as a critical renewable energy technology to reduce GHG (Green House Gas) emission and autonomy in energy production. Each of these wind farms consist of many Wind Turbine Generators (WTG) mounted on a support structure and are capable of generating up to 1.2GW of power. These are relatively new technological advancements which are installed in harsh offshore environments. Naturally, the design of foundations for such structures are challenging. The aim of the lecture is to discuss the challenges in designing foundations for such structures and how to obtain loads on the foundations.
Scaled model tests are currently being used to design such structures. The rationale behind scaled models tests that supported the development of offshore Wind Turbine design philosophy will also be discussed. Methods to scale the such model tests for predicting prototype consequences will be illustrated. Finally, the lecture will conclude that well thought out scaled models tests can be effective in predicting the long-term issues and engineers must also need to learn from other disciplines.
Professor Bhattacharya currently holds the Chair of Geomechanics and directs SAGE (Surrey Advanced Geotechnical Engineering) laboratory, a specialized soil mechanics/geotechnical engineering laboratory for research and industrial testing. He is also the Programme Director for the specialized MSc course on Advanced Geotechnical Engineering. He is also adjunct professor at Zhejiang University (China) and Visiting Fellow at the University of Bristol (UK). Previously, Professor Bhattacharya held academic posts at: University of Bristol (Senior Lecturer in Dynamics), University of Oxford (Departmental Lecturer), Junior Research Fellow (Somerville College, Oxford), 21st Century Centre of Excellence Fellow (Tokyo Institute of Technology). He has more than 20 years’ professional and research experience in the behaviour and design of foundations in extreme environments. He has recently published over 25 papers on the dynamics of wind turbines including Soil-Structure Interaction and an integrated design method for the design of monopiles.
