Floating offshore wind presents unique operations and maintenance challenges, such as monitoring and replacing mooring lines and dynamic cables. For floating wind to successfully transition to commercialization, the industry needs a stronger understanding of component failure modes, the time and cost of repairs, and their impact on operational expenses.
ORE Catapult’s Floating Offshore Wind Centre of Excellence will deliver the project alongside Apollo Engineering and DOF Subsea UK.
Sean Snee, Floating Offshore Wind Team Leader at ORE Catapult, said: “Operating and maintaining a floating offshore wind farm creates challenges not previously faced in fixed offshore wind, including the monitoring and replacement of mooring lines and dynamic cables.
“More data is required to accurately assess key component failures and what leads to them. In identifying preventative measures and innovative technologies, the learnings from this project could reduce the overall cost of floating offshore wind mooring lines and dynamic cable repairs and replacement across the UK and internationally.”
The “Mooring line and dynamic cable monitoring and replacement methodologies” project will provide comprehensive insight into the monitoring and maintenance requirements for floating wind dynamic cable and mooring line components. Historically, mooring repair costs for oil production assets have exceeded £400 million for a single incident, while cable failures have accounted for 70–80% of UK offshore wind insurance claims.
Will Brindley, Lead Naval Architect, Apollo Engineering, said: “Understanding the specific requirements of mooring and cable repair is essential to minimize floating wind costs. The insight gained from this study will allow the next generation of gigawatt-scale arrays to be designed, built, and operated with long-term integrity and maintainability in mind.”
Mike Kearney, Renewables Project Manager, DOF Subsea UK, added: “We’re proud to be collaborating with Apollo and ORE Catapult, bringing together innovation and operational know-how to help commercialize floating wind at scale.”
The Floating Offshore Wind Centre of Excellence is an internationally recognized center of excellence in floating offshore wind, supporting and developing opportunities for the local supply chain, helping to drive and derisk innovation in manufacturing, installation, and Operations and Maintenance methodologies in floating wind.
Its mission includes establishing the UK as the world’s leading floating offshore wind market and attracting investment in floating offshore wind research and development in the UK.
