Geotechnical surveys for EGL1 began in English waters on approximately 1 July 2025. The geotechnical campaign was managed by Prysmian with subcontractor HDI and executed from the barge Sandpiper. The works comprised boreholes, cone penetration tests (CPTs) and vibrocore sampling along the planned subsea route to characterise seabed sediments and subsurface conditions for trenching, burial depth assessment and cable protection design. The campaign was weather dependent and intended to provide site-specific ground data to finalise installation methodology and engineering.
