For ORE projects to be best integrated into the marine environment, it is important to know the interactions between these new types of infrastructures and coastal marine ecosystems. Within the framework of calls for tenders issued by the French government for the installation and operation of offshore wind farms, the question of the impact of subsea power cables is regularly raised during the consultation phases. This is also a point that is carefully examined by the environmental authority that assesses the regulatory impact studies of wind power projects. Although the direct impacts of electromagnetic fields and temperature emitted by cables are often considered to be low within the community of scientific experts, there is nevertheless a lack of data from environmental monitoring of existing projects to address these issues.
To enhance knowledge of the potential impacts of ORE electric power cables on coastal ecosystems.
