Description du projet
Des ancres partagées pour réduire les coûts de construction des éoliennes flottantes
Le plan stratégique européen pour les technologies énergétiques englobe la recherche et l’innovation dans le domaine de l’énergie éolienne en mer. Des régions potentielles caractérisées par des conditions de vent constantes et un impact visuel minimal sur les côtes ont été identifiées. Ces régions se trouvent en eaux profondes, ce qui incite à explorer les éoliennes flottantes comme une alternative viable. Cependant, les dépenses de construction liées aux plateformes et aux systèmes d’amarrage sont considérables. Une solution consistait à utiliser des ancres communes reliées aux systèmes d’amarrage. L’initiative ShareWind financée par le programme MSCA permettra de développer des modèles physiques, d’établir des lignes directrices en matière de conception et d’évaluer la capacité de charge des ancres partagées déployées dans des profils de fonds marins argileux. Des simulations numériques et des études paramétriques permettront de vérifier les enveloppes de rupture des ancrages exposés à des charges cycliques multidirectionnelles.
Objectif
"On the framework of the energy transition in Europe, new technologies are under research, development and implementation. One of the targets of the European Commission is by 2030 to achieve a 32% of energy capacity based on renewable sources . Offshore wind energy is one of the renewable energy sources contemplated in the European Strategic Energy Technology Plan (SET Plan) as part of the actions for research and innovation. New potential areas with more intense and stable wind conditions and minimized visual impact on the coastline have been identified (deep waters of >60 m depth). This motivates the idea of implementing floating wind turbines as an alternative to reach deep water locations with a great potential as a step further in the offshore wind industry. One of the main challenges for this technology is the cost associated with the construction of the platforms for the wind turbines and the mooring systems to anchor the turbines in deep water. One of the solutions to optimize offshore floating wind farms costs is sharing the anchors connected to the mooring systems that secure the wind turbines when subjected to the ocean environmental laods. The research proposed here ""Shared anchors for floating wind turbines- ShareWind"", aims to provide design guidelines and evaluate the loading capacity of shared anchors installed in clayey seabed profiles as most of the research on this topic has been adressed in sands. As part of ShareWind, the applicant will (i) develop physical models of shared anchors to be tested at theUniv.Eiffel (France) geotechnical centrifuge, (ii) perform numerical simulations and parametric studies to provide design guidelines and failure envelopes of anchors subjected to multidirectional cyclic loading. The results of ShareWind will be integrated in design frameworks to predict the loading capacity and displacements of shared anchors with impacts in their long-term performance and in the optimization of costs of floating wind farms."
