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 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

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

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.

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.

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.
