Environmental Impacts of ORE and OWF: Analysis and Assessment
- Impacts due to both floating and fixed OWFs
- Impact of noise and vibration
- Impact of collisions on birds and bats
- Impact on the water column and ecosystem functioning
- Impact on fish and fisheries
- Impact on marine mammals and large migratory species
- Impact on the seafloor and benthic habitats
- Impact of submarine power cables
- Figure 2 Comprehensive list of environmental components to be considered for a rigorous EIA (environmental impact assessment) is presented in schematic of Danovaro et al. (Renewable and Sustainable Energy Reviews, 197, 114386., 2024)

Specific Impacts of fixed OWFs on the marine ecosystem – shallow water
- Wind wake effect in shallow water – affects hydrodynamics: – circulation, stratification, mixing;
- Impacts upon primary production (PP) and ecosystem functioning - potential substantial impact on the structuring of coastal marine ecosystems on basin scales
