Offshore wind energy is a major component of the UK’s energy mix, with nearly 2500 offshore turbines either operational or being constructed, and many more planned for the next few decades. Similarly ambitious plans exist across Europe and elsewhere in the world. Advanced engineering design plays a crucial role in reducing capital and operational costs, and is necessary for the wind energy industry to be sustained. This lecture will explore how Oxford Engineering Science is addressing critical design challenges facing the offshore wind industry, with a focus on civil and geotechnical design (e.g. foundations, structures), including the application to next generation offshore wind farms.
