ABIOP project : better understanding of biofouling


Innovative work and promising results

The impact of biofouling developing on MRE, both environmental and technical, is still poorly understood. However, it is crucial to better characterize this phenomenon so that it is taken into account from the design phase of offshore energy recovery systems, in order to optimize their sizing and maintenance. Initiated in March 2017 and completed last week, the ABIOP collaborative R&D project is addressing this issue.
It was conducted along two axes:

  • The realization of an in-depth synthesis of knowledge on biofouling at the level of the various French maritime facades. This will soon be published in the form of an atlas much awaited by the various actors in the sector;
  • The development and implementation of experimental protocols to characterize biofouling at two sites off the Croisic in the Atlantic and a site near Banyuls in the Mediterranean. PVC sheets and sections of nylon tips were immersed for 1 year at a depth of several metres (3, 5 and 10 m). Different techniques were then used to characterize and quantify the species present on the colonized supports: analysis of 3D images obtained using stereoscopic cameras, taxonomic study and metagenomic approach.

During the closing meeting, the 9 partners discussed the results obtained and the very promising results of ABIOP, which will soon be reflected in a new project called ABIOP+.
