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

Numerical simulations applied on the study sites

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.

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.

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

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

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.
