Marine dunes, whether tidal or non-tidal, are highly variable sedimentary structures relatively frequent in the North Sea and the English Channel, where future offshore farms are planned. Because of their movements, they can lead to scour around foundations (monopile or substation) and burying or exposure of cables, thus having implications for the design, implementation, longevity and safety of offshore renewable energy devices.
To predict the dunes impact on offshore wind farm components, the MODULLES R&D project worked on modelling marine dune dynamics and their interaction with the OWF infrastructures at different scales. The project also investigated the future needs to combine physical and ecological aspect of the marine dunes and understand their resilience after the construction phase.
Register now to discover the main results of the project:
- Small-scall numerical modelling of the sediment transport close to a monopile
- Large-scale modelling and interactions between marines dunes and OWF infrastructures
- Investigation of the dune resilience in an ORE context
- Results transfer to the ORE sector (Conclusion by RTE)
