Equinor ASA, as owner and operator of Hywind Scotland, is responsible for the ongoing inspection and maintenance of the project’s subsea electrical infrastructure, including the export cable to shore. Under its operations and maintenance programme, Equinor plans and executes campaign‑based surveys of the substructures, mooring systems and subsea cables, currently on a bi‑annual basis, using internal subsea competence. Equinor also provides high‑voltage switching services on the turbines and at the onshore substation via its Great Yarmouth wind control centre, ensuring safe operation and isolation of the export connection during maintenance activities.
