Polish research company MEWO was contracted to inspect the seabed for potential unexploded ordnance (UXO) and duds along the offshore cable routes and turbine locations for the Bałtyk 2 and Bałtyk 3 projects. The UXO survey campaign covered the submarine export cable corridors and wind farm areas in the Polish Baltic Sea, providing clearance certification ahead of the offshore construction and cable installation campaigns. This survey work was completed in spring 2025 as part of the broader offshore site preparation programme.
