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.

This study is a numerical experiment to evaluate the sensitivity and specificity of a set of ecosystem indicators, including ANS, to fishing pressure.

This report outlines the proposed architecture and main functions of the DTOcean mooring and foundation design module and its interaction with other elements and modules of the tool

Monitoring data on biomass (fresh weight in air and water), biovolume, thickness.

Measurement of the diameter of biocolonised moorings and biofouling composition at T+6 months of immersion.

This deliverable consists of two parts. The first one is a comprehensive review of all the electrical infrastructure technologies between the converter and the point of connection to the onshore electrical grid. The second one is a set of operating regimes of the ocean energy conversion arrays

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.

Review to identify the state of knowledge on anodes and their environmental impact. Report serving as a basis for further work (deliverables 3 and 4)

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.

This report studies the effect of the cumulative effects of climate change and the reef effect induced by the implementation of the Courseulles sur mer wind farm on the emergent properties of the ecosystem, as well as the sensitivity of the ENA to a cumulative impact.
