Envision Ltd reanalysed raw geophysical and benthic characterisation data along the offshore export cable corridor (Offshore ECC) for the Outer Dowsing Offshore Wind project, confirming that no qualifying Annex I biogenic reef was present within the offshore ECC. The work supported the project’s biogenic reef mitigation planning and informed pre-construction survey and micrositing/routeing commitments within and near the IDRBNR SAC.
