Setec delivered environmental baseline study inputs for the Centre Manche 1 offshore wind project area (also referred to as Éoliennes en Mer Manche Normandie / AO4 Centre-Manche 1). The project information page lists Setec as the author of a “Note bibliographique” and associated survey protocols focused on “mégafaune marine” (marine megafauna), which typically covers offshore ecology receptors such as marine mammals and other large marine fauna relevant to impact assessment and monitoring planning. This scope formed part of the “État initial de l’environnement” (initial state of the environment) work package presented among the key environmental and usage studies for the Centre-Manche zone. The deliverables indicate Setec’s role was to compile and synthesise existing knowledge (bibliographic baseline) and to define methodologies/protocols to guide subsequent field campaigns and reporting for marine megafauna within the project’s pre-construction development phase. No contract value, award date, or commissioning client is stated on the page, and no quantities are provided. The reference is presented as part of the publicly accessible study catalogue linked from the official project information site.
