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

During the ABIOP project launch meeting, the consortium agreed to add a task to the project aimed at identifying the challenges of biocolonisation in an ORE context. This additional work is indeed necessary because it allows the organisation, updating and presentation of the reflections undertaken by biofouling experts from various industrial and research entities and federated by FEM, for several years on this topic.

Backup of the data used for characterising the different biofouling monitoring protocols in an excel file.

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

Excel database containing the information collected for the atlas (45 sources for the French maritime façades + 24 on a global scale) and shapefiles for the cartographic representation of the available data

Numerical simulations applied on the study sites

The macrofouling qualification and quantification protocols were extracted from 64 public documents (33 scientific articles, 1 book chapter, 22 internal reports, 4 internship reports and 4 theses) presenting studies conducted in France (n = 40), Europe (n = 16) and the world (n = 8).

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)

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.
