The main project objective is to reduce the cost of energy (LCOE) of floating wind by 50% through the validation of the "PivotBuoy" (TRL3), an innovative subsystem that reduces the costs of mooring systems and floating platforms, allows faster and cheaper installation and a more reliable and sustainable operation. The PivotBuoy system combines the advantages of Single Point Mooring systems (SPM - pre-installation of the mooring and connection system using small vessels) with those of tension-leg systems (TLPs - weight reduction, reduced mooring length and enhanced stability), enabling a radical weight reduction of 50% to 90% in floating wind systems compared to current spar and semi-submersible systems but also enabling a critical simplification in the installation of traditional TLP systems. The project proposes validating the concept at PLOCAN test site, integrating a part-scale prototype of the PivotBuoy single point mooring system in a 225kW downwind floating platform developed by X1 WIND. By testing in a relevant environment, the project will also validate critical innovations related to assembly, installation and O&M techniques, reaching TRL5 at the project end.
- Study on the logistics of the operation & maintenance of 50 floating 5MW wind turbines off the Canaries, using the PivotBuoy concept.
- Numerical simulation of this device, using CFD (computational fluid dynamics) to estimate the loads under extreme wave conditions.
- LCOE modelling
- Development of a business case and life cycle analysis (LCA)
