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

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

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.

Configuration of the ocean model and biogeochemical modules

The main objective of this atlas is to summarise the knowledge acquired on biofouling, and more generally on communities of living organisms on hard substrates, available today in mainland France and the French overseas territories, in order to anticipate the issues that this phenomenon will pose in an ORE context. The atlas is based on the most exhaustive bibliographical analysis possible, including A-level scientific articles, reports (training courses, monitoring, studies), and works presenting the results of studies conducted in French waters

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.

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

Database of images collected at ABIOP monitoring sites (UTLN = Mola buoy offshore Banyuls, SEMREV = special marks east and north, UN = biocolmar buoy) + report on biofouling characterisation (rapport_taxo_ABIOP_provisoire)

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).
