Projet
ABIOP
Accounting for biofouling through established protocols of quantification
- Duration: 22 months (2017-2018)
- Budget: €540K
Context
The effects and magnitude of biofouling on offshore renewable energies 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.
Objective
- To develop biofouling characterisation and quantification methods for reliable design and maintenance of offshore renewable energy systems
Main achivements
Literature review and georeferencing of studies carried out on biofouling on French coastlines
Review of biofouling issues encountered for the various offshore renewable energy technologies
Improvement of image analysis protocols for macrofouling integrating environmental measurement conditions
Recommendations for optimising the positioning of biological expertise
Specification of sensor requirements in terms of accuracy and reliability
Main outputs
- Bibliographic atlas of the biofouling of French coasts in an offshore renewable energy context
- Databases: bibliographic atlas and image analysis protocols
- Video system with antifouling protection that can be deployed at depths of up to 200 m
Conclusion
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.
