AB Mobility of the sedimentary substrate, both through the flow of sedimentary particles and through the migration and evolution of sedimentary structures, has direct implications on the design, implementation, longevity, and safety of ORE (ocean renewable energy) devices. Marine dunes are very present on the English Channel and North Sea coast where most of the future Europeans offshore windfarms (OWF) are located and planned to be constructed. Cable installation and foundations for OWF in this environment is a challenge due to the seabed mobility. This mobility can bring risks of cable over-burying or un-burying and uncertainties about foundations scouring conditions. Consequently, there is a need to anticipate variations in sediment thickness to limit damage to infrastructure and to design anti-scouring protection and better anticipate OWF costs. Furthermore, marine dunes are areas of high ecological importance. It is therefore important to understand the effect that the installation of MRE infrastructure can have on dune morphodynamics to limit the impacts on the ecosystem. To address all these issues for OWF industry, two research and development collaborative projects have been set up: DUNES & MODULLES. The first project (DUNES) aimed at collecting in situ data on seabed, hydrodynamics and ecosystem via bathymetric surveys, current measurements and biological sampling. The second one (MODULLES) aims to model the influence of these dunes on offshore wind farms at different spatio-temporal scales from a few seconds and centimeters to several years and kilometers via numerical and physical modeling. During MARID, marine dunes issues for ORE sector will be depicted. An overview of the DUNES and MODULES projects will be given to present how we address these issues with research and development project.
