Measurement of the diameter of the biocolonised moorings and the composition of the biofouling at T+12 months of immersion.

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

Proposal of protocols for measuring several biofouling variables (fresh weight in air, fresh weight in water, biovolume, thickness) that were tested during the project.

Report describing the methodology and results of the simulations

The objective of the ABIOP project was to develop biofouling characterisation and quantification methods to make the design and maintenance of ORE systems more reliable. ABIOP has identified the research needs that will enable better identification and management of the risks relating to the ORE components most sensitive to biofouling. Initial in situ measurements were also carried out to characterise biocolonisation in the Atlantic and Mediterranean from an engineering and environmental point of view. The necessary additional studies are being carried out within the framework of the ABIOP+ project.

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

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).

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.
