Mutualised anchors for offshore wind farms
In Europe, around 80% of the offshore wind resource is located in waters more than 60 metres deep, where floating offshore wind turbines are seen as technologies capable of satisfying environmental constraints and ensuring a competitive levelized cost of energy. After the deployment of demonstrators and pilot farms, the next major stage is that of commercial wind farms, which raises the question of the morring systems to be used to ensure sufficient profitability.
MUTANC has shown that loads on shared anchors vary according to depth and type of mooring. It also appears that multidirectional and cyclic loadings on a pile in sand lead to variable displacements, which often increase with the intensity and directionality of the loads. Finally, the techno-economic analysis highlighted cost reductions of 16 to 33% when using shared anchors, validating the potential of such a solution applied to floating wind farms.
Ce projet was led by France Energies Marines, Technip Energies and Saipem.
This project received French State funding managed by the National Research Agency under the France 2030 investment plan (ANR-10-IEED-0006-34). It also received financial support from the Pays de La Loire region, Nantes Métropole and Pôle Mer Bretagne Atlantique.
