Accounting for biofouling through established protocols of quantification

Duration: 18 months (2017 - 2018)


The effects and magnitude of biofouling on marine renewable energies (MRE) systems are largely unknown and represent a challenge to the sector in the design and maintenance phases likely to impact the final technology LCOE. It is therefore crucial to provide reliable input data needed for engineering based on studies coupling marine biology, marine metrology and structural design.


To develop biofouling characterisation and quantification methods. Développer des méthodes de caractérisation et de quantification du biofouling for reliable design and maintenance of ORE systems.

Scientific and technical contents

  • Bibliographic synthesis and georeferencing of studies carried out on biofouling at the level of French coasts.
  • State of the art of biofouling issues encountered for the different ORE technologies.
  • Improvement of image analysis protocols for macrofouling integrating environmental measurement conditions.
  • Recommendations to optimise the positioning of biological expertise.
  • Specification of sensor requirements in terms of precision and reliability.
