This TAILWIND factsheet explores how more sustainable station-keeping systems can support the scale-up of floating offshore wind. It focuses on anchor concepts and fibre rope mooring lines, highlighting how design choices can reduce material use, environmental impact and end-of-life challenges. The factsheet also looks at shared-anchor opportunities, recycling pathways and key bottlenecks for fibre rope recyclability, showing why sustainability needs to be considered from early design to decommissioning.
