À propos de nous
Nantes Université est un établissement public d’enseignement supérieur et de recherche qui propose un modèle d’université inédit en France unissant une université, un hôpital universitaire (CHU de Nantes), un institut de recherche technologique (IRT Jules Verne), un organisme national de recherche (Inserm) ainsi que Centrale Nantes, l’école des Beaux-Arts Nantes Saint-Nazaire et l’École Nationale Supérieure d’Architecture de Nantes.
Ces acteurs concentrent leurs forces pour développer l’excellence de la recherche nantaise et offrir de nouvelles opportunités de formations, dans tous les domaines de la connaissance.
Durable et ouverte sur le monde, Nantes Université veille à la qualité des conditions d'études et de travail offertes à ses étudiantes, étudiants et personnels, pour favoriser leur épanouissement sur tous ses campus de Nantes, Saint-Nazaire et La Roche-sur-Yon.
Mission
The SLOOP project, funded by the ORACLE LabEx, addresses critical challenges in offshore wind turbine (OWT) design: the transition from deterministic to stochastic modelling. As OWTs move into deeper waters and larger scales, standard design methods struggle to capture the complex, long-term cumulative displacements caused by stochastic, multidirectional marine environments. SLOOP aims to bridge the gap by integrating advanced aero-hydrodynamic load simulation with high-fidelity geotechnical response modelling.
As a core member of the SLOOP research team, the Postdoctoral Researcher will contribute to Work Package #2, focusing on the soil-pile interaction under realistic offshore loading conditions. Key tasks include:
- Offshore Monopile Loading Analysis: Integrate aero hydrodynamic load time series generated at École Centrale de Nantes using Morison’s equations, potential-flow theory, and OpenFAST into the geotechnical modelling workflow.
- 3D Finite Element Modelling: Develop, calibrate, and refine high‑fidelity ABAQUS models of monopile–sand interaction. Use geotechnical centrifuge data from Gustave Eiffel University to calibrate advanced soil constitutive models (Hypoplastic, SANISAND). Simulate monotonic, unidirectional cyclic, and multidirectional loading conditions.
- Design Tool Development: Develop simplified or macro‑element models for cyclic loading. Contribute to improved P–y curves, stiffness‑degradation laws, and long‑term displacement prediction.
- Collaboration and Dissemination: Participate in co-supervision of MSc interns. Work closely with hydrodynamics experts (ECN) and centrifuge specialists (UGE). Contribute to project deliverables and progress meeting. Prepare journal papers and conference contributions.
We offer a highly collaborative research ecosystem that connects three leading laboratories: GeM at Nantes Université, providing advanced expertise in soil mechanics; LHEEA at École Centrale de Nantes, a world‑class center for hydrodynamics modelling; and the Geotechnical Centrifuge Laboratory at Gustave Eiffel University, home to France’s national centrifuge testing facility. We provide access to high‑quality experimental and numerical datasets from major offshore geotechnical projects—including SOLCYP, SOLCYP+, MUTANC, and SLOOP. We provide new personal workstation and access to high-performance computing resources for numerical simulation. We support publication in top journals and participation in international conferences. We foster an interdisciplinary research collaboration within the ORACLE LabEx network, linking geotechnics, hydrodynamics, and offshore renewable energy.
