The objectives of the DUNES project are on the one hand to understand the sedimentary and ecosystem dynamics of underwater dunes, and on the other hand to provide technology developers and industrialists in the ORE sector with complementary knowledge and approaches to work in environments with hydraulic dunes. The expected results are first of all to have a better knowledge of the physical processes and the natural functioning of hydraulic dunes, to create a free access GIS dedicated to dune fields and sandbanks, to characterize on a fine scale of the structure of food webs in dunes to understand the functioning of these particular systems, and finally to establish methodological recommendations regarding the evaluation of anthropogenic impacts on dune ecosystems.

The objectives of the ABIOP+ project were to : • Provide characterisation protocols for biofouling on cable and mooring lines materials which are very vulnerable to this biological process, in order to collect quantitative in-situ data. • Inventory existing fouling management methods and test the solutions best suited for floating offshore wind turbines.

The objective of the DiMe project was to improve the characterisation of extreme sea states with breaking waves by combining observations and modelling.

The objective of the CASSIOWPE project was to support the development of offshore wind energy in the French Mediterranean coastal areas by providing a database of high-resolution observations of wind, wave and current fields as well as a new numerical tool for the modelling of metocean conditions in the Gulf of Lion.

The objective of the TROPHIK project was to model the role of offshore wind turbines and other anthropogenic activities in modifying the functioning of thefood webs of the Bay of Seine by taking climate change into account. TROPHIK has initiated a methodology to move from the sectoral vision of environmental impact studies to a functional and holistic approach. The analysis of the sensitivity of the functioning of the food web to the development of offshore wind farms represents a solid basis for recommending new areas of implantation. This approach will be completed within the framework of APPEAL and WINDSERV by integrating the societal and economic environment as well as biogeochemical forcings

The objectives of the DYNAMO project are: - to develop recommendations for the optimisation of in-service monitoring solutions for subsea cables at the farm leve - to propose a roadmap for the development of the identified promising technologies

The objective of the ANODE project was to quantify the chemical compounds emitted by the galvanic anodes of ORE structures and the risk associated with their dispersion in the marine environment. By combining ecotoxicological expertise and hydrodynamic modelling, the ANODE project has determined that there is no risk associated with most of the elements making up galvanic anodes, namely zinc, iron, copper and cadmium. On the other hand, concerning aluminium, additional experiments are necessary to conclude. The two currently available Predicted No-Effect Concentrations (PNECs) do not seem suitable for this assessment. These thresholds must therefore be refined and include data from in situ measurements in order to be able to estimate the possible risk associated with aluminium releases.

The objectives of the AESTUS project were: • To develop and finalise the tools and procedures necessary to create relevant databases. • To analyse these databases to acquire new knowledge on turbulent phenomena within high intensity flows that can be used by engineering companies for their design studies.

The objectives of the DTOcean project were: • To accelerate the industrial development of knowledge related to wave and tidal energy production. • To provide design tools for the deployment of the first generation of ocean energy systems.

The objective of the CARAVELE project was to improve the characterisation of extreme winds by combining atmospheric models with satellite and in-situ observations.
