Consideration of biofouling using quantification protocols useful for engineering

Duration: 36 months


Increasing the competitiveness of ORE (linked to the decline in LCOE) is essential to their development. An optimized design and an appropriate maintenance plan for structures and farms are therefore necessary. In this context, the development of organisms living on elements immersed in the sea, also known as biofouling, is a crucial parameter to be taken into account.
This biological process, which affects all types of structures, is not fully understood, especially considering the very dynamic and shallow sites characteristic of ORE system siting areas. Several studies, including the ABIOP project, highlight that biofouling is a critical problem for mooring lines and dynamic cables.


To characterize biofouling qualitatively and quantitatively according to the sites and components concerned using innovative, inexpensive and globally applicable protocols based on sound data analysis.

Expected results

  • Better knowledge of biofouling at ORE sites including differences between sites (Atlantic and Mediterranean) on a large scale and a detailed characterization over 4 years.
  • New protocols and approaches for the identification and quantification of biofouling and its effects for consideration in structural design.
  • Answers to questions specific to mooring lines and dyanmic cables: effects of cyclic stresses, thermal effect of biofouling...
  • Proposal of biofouling management solutions adapted to ORE among those from other industrial sectors, emphasizing the need for a sustainable approach.

Scientific contents

  • Multi-scale characterisation of biofouling
  • Improvement of biofouling characterisation protocols on standardisation, operability and cost aspects
  • Development of a quantitative image analysis method
  • Evaluation of existing solutions to manage biofouling
