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)

Report on the assessment of the chemical risk of aluminum-based galvanic anodes on the environment

To reduce the number of interventions and maintenance operations, it is necessary to monitor the proliferation of marine fouling in real time and over a long period. This is why it is necessary to have an in situ optical video system that is protected for as long as possible against biocolonisation.

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.

Conclusion and recommendation report resulting from the results of the ANODE project and published by FEM editions

Synthesis of existing data for the modeling work to follow (modeling in the deliverables of lot 3)

Numerical simulations applied on the study sites

Configuration of the ocean model and biogeochemical modules

Report describing the methodology and results of the simulations

This report focuses on two important parameters for biofouling image analysis: the artificial light and the distance to the structure. The first section presents the available tool that was already deployed in several studies in link with industrial needs (O’Byrne et al., 2018c) and the laboratory equipment. Section 2 focuses on the automatic segmentation algorithm and the indicators of quality of assessments. Finally section 3 introduces configurations that were tested and the key results.
