So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!
PO083: Pre-stretching effect on polyester and nylon mooring lines for commercial wind farms in deep waters
Marie Feron, Offshore Wind Naval Architect, TotalEnergies
Abstract
The floating offshore wind market is expected to grow very quickly in the next coming years and is now starting to develop in deep waters (typically above 400m). The associated Floating Offshore Wind Turbine (FOWT) mooring systems will typically be made of synthetic fiber ropes. The benefits from the available competitive technologies (mainly polyester and nylon) shall then be clearly identified. In this context, DORIS, Bexco and TotalEnergies have performed an R&D study where the objective is to compare the response of FOWT mooring systems based on nylon vs polyester, for deep waters application, in order to understand the pros and cons of both synthetic materials. In particular, based on available test results from manufacturers, the mooring response has been evaluated accounting for mechanical properties achieved when no pre-stretching operations is performed during installation. The FOWT system studied here is based on the NereWind semi-submersible developed by DORIS and the IEA Wind 15-MW reference turbine with the associated floating tower designed by the NREL.. This work will allow floating offshore wind farms developers and floating concept designers to understand better the synthetic mooring for floating wind and shows how pre-stretching operation could be avoided.
