Description du projet
Des installations éoliennes offshore plus sûres
L’énergie produite à partir d’éoliennes flottantes (offshore) est de plus en plus populaire. Cependant, la demande en matière de sécurité, d’entretien et d’optimisation du coût est de plus en plus pressante. Les installations éoliennes en mer comportent des connexions adhésives qui doivent être remplacées et utilisent un système de collage spécifique. Le projet ASSO, financé par l’UE, préparera une étude solide, testera et évaluera cette opération et la précision de sa procédure numérique. Le projet inclut également la création d’un modèle mécanique non linéaire innovant. Il évaluera l’impact de l’eau de mer et d’autres facteurs physiques sur l’état, le comportement et la capacité de résistance des connecteurs adhésifs. Ce projet multidisciplinaire comprendra des essais expérimentaux, un modèle mécanique non linéaire, une analyse basée sur la méthode des éléments finis (FEM), des transferts de connaissances et des formations.
Objectif
The development of floating (offshore) wind turbines on a commercial scale is expected to grow considerably over the next few years after that different countries have recognized them as the best solution for the production of sustainable energy. In order to satisfy the required needs of safety, serviceability, durability and affordability, the actual connections and the secondary structures have to be replaced by a new ones based on the bonding technique.
The ASSO project has the principal purpose to establish a sound framework for the feasibility and assessment of adhesive connections for offshore wind installations in the marine environment, including experimental tests and accurate numerical procedures.
In this framework, the ASSO project aims to develop: an innovative non-linear mechanical model able to investigate the influence of seawater on the performance of adhesive connections in the presence of leading causes of degradation, ageing and vibrations (due to the waves); an experimental database in order to predict their service life investigating the long-term behaviour and resistance in seawater environment. Consequently, in order to increase the knowledge of adhesive connections in the marine environment, the project is composed of the following three different levels: experimental tests, non-linear mechanical model and FEM analysis. The multidisciplinary nature of the project is strong, involving aspects of mechanical engineering, structural engineering, environmental engineering, applied mathematics, numerical analysis and advanced materials design.
The proposal includes both the transfer of knowledge to the host institution and the training of the candidate in new advanced techniques. Results have the potential capacity to increase the diffusion of offshore wind installations for sustainable energy production, an ambitious target in line with the EU strategy.
