Consideration of biofouling using quantification protocols useful for engineering

Duration: 40 months (2019 - 2022)


Increasing the competitiveness of ORE (linked to the decline in LCOE) is essential to their development. An optimised 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 provide characterisation protocols for biofouling on cable and mooring lines materials which are very vulnerable to this biological process, in order to collect quantitative in-situ data.
  • To inventory existing fouling management methods and test the solutions best suited for floating offshore wind turbines.
