Proud to share that iWind Renewables participated in the International Offshore Wind Technical Conference (IOWTC) 2025 in Toulon, France, where we presented our latest work on mooring systems for floating offshore wind turbines — covering semi-submersible, spar-buoy, and TLP concepts at 200–300 m water depths .
This study — funded by Teufelberger-Redaelli and conducted in collaboration with the National Technical University of Athens — explored hybrid-catenary mooring systems with steel wire, polyester, and Dyneema ropes, assessing both technical performance and cost efficiency.
Highlights:
• All configurations proved technically viable with comparable coupled dynamic behavior.
• Hybrid rope–chain systems reduced mooring material costs by 30–90% for semi-sub and spar designs compared to the conventional all-chain solution.
• Steel wire and polyester systems showed similar costs (±10%).
• For TLPs, steel wire ropes offered up to 45% cost savings versus Dyneema, with better stiffness performance.
