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.  iWind Renewables participated in the 7th Renewable & Storage Forum, organized by energypress.gr and held at Ethniki Asfalistiki Conference Centre in Athens, Greece on 22-23 October 2025. Panagiotis Chaviaropoulos took part in the Section 4 panel discussion on "Offshore RES Systems". You can watch the full discussion in Greek or English. Dimitris Manolas delivered a presentation titled "Optimal techno-economic design of floaters and moorings in the Aegean". You can watch the presentation in Greek or English.

 A new handbook on wind turbine aerodynamics has been made available recently. We are pleased that two of iWind's partners were invited to contribute to the "Handbook of Wind Energy Aerodynamics". It is edited by well known experts in the field (Bernhard Stoevesandt, Gerard Schepers, Peter Fuglsang and Yuping Sun) and includes contributions from numerous industry and research experts.
The contributed chapters are "Economic Aspects of Wind Turbine Aerodynamics" and "Rotor Blade Design, Number of Blades, Performance Characteristics". The first chapter deals with the connection between LCoE (Levelized Cost of Energy) and technological selections and design aspects, with focus on rotor aerodynamics. The second one is related to the design of the blade planform and the choices about the main geometrical characteristics of the blade, namely chord, twist and blade thickness. |
