Offshore Demonstration Site Demand and Feasibility Study.
Abstract
In late 2022, Opergy was commissioned by Natural England to conduct a desk-based research study assessing the demand and feasibility of an offshore demonstration site in English waters. This initiative aims to bolster the UK's extensive offshore wind capacity while mitigating environmental impacts through pre-commercial scale trials of new technologies. The study evaluated 46 offshore trial sites globally, revealing a gap in facilities focused solely on environmental impacts. Key findings indicated a broad support from statutory bodies and industry representatives for such a site, emphasizing its potential to complement existing work and help the UK meet net zero targets. Stakeholders highlighted critical areas for targeted research, including impacts of cable trenching, anchoring systems, biofouling prevention, corrosion protection, and cumulative effects on marine life. The study recommended leveraging existing infrastructure and fostering a network of test sites to minimize duplication and reduce development costs. Strong support was found for new sites with diverse seabed environments to address specific testing needs. An online survey corroborated the necessity of accessible trial facilities in the UK, with a significant demand cited by 60% of respondents. The study concluded with recommendations for Natural England, including promoting environmental impact management, developing a network of demonstration sites, engaging with potential partners, and establishing governance and funding arrangements.
