The project

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. While Britain is presently the global leader in offshore wind energy, the national target set by the UK government to increase the installed capacity of offshore wind energy from approximately 10 GW in 2020 to 40 GW in 2030 demonstrates the strategic importance of this clean source of energy for the UK’s energy mix

Offshore wind turbines (OWTs) are typically designed for 20-25 years of operation. One of the main barriers for extending the operational lifespan of OWTs beyond 25 years is the evolution of corrosion-fatigue damage due to the constant exertion of wind, wave and current variable amplitude forces in the highly corrosive environments. The overall aim of this project is to develop permanent additively manufactured protective layers, as a novel coating technology, in the critical areas of offshore wind turbine (OWT) support structures. This will extend the lifespan, optimise and reduce the number of frequent inspections and deliver a direct beneficial impact on Operations and Maintenance (O&M) costs of OWTs.
