National Grid (in partnership with SSEN Transmission) deployed four uncrewed survey vessels (USVs) from Scarborough at the end of April 2025 to begin geophysical seabed mapping for Eastern Green Link 5. The XOCEAN-operated USVs carried multibeam echo sounders and sub‑bottom profilers to collect bathymetry, seabed and shallow sub‑seabed data along the proposed EGL5 route, supporting route engineering, environmental assessment and archaeological appraisal.
