Marine Dune Dynamics and Offshore Wind Farms
Published on 07/10/2024
Better understanding marine dune dynamics in an offshore wind farm context is essential.
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.
Final webinar
This project has come to an end and a final webinar was held on 17 October 2024, from 2:00pm to 3:30pm CEST (Paris time).
It presents the main results of the project.
