Offshore Site Preparation

In January 2026, subsea rock installation (SRI) began in the Baltic Sea for the Bałtyk 2 and Bałtyk 3 offshore wind farms. Specialist vessels from Van Oord commenced placing rock material in designated seabed areas to provide scour protection around monopile foundation locations and to prepare the submarine export cable routes for safe installation. This SRI campaign represents a distinct phase of offshore site preparation following the earlier boulder relocation works completed in 2025 by Helix Robotics Solutions using the i-Plough under the Jan De Nul and Hellenic Cables consortium contract. The rock installation protects the seabed infrastructure from currents and wave-induced erosion and prepares the cable corridors ahead of the main offshore installation campaign planned for spring-summer 2026, during which monopile foundations, offshore substations, and the 220 kV HVAC submarine export cables for the Bałtyk 3 Export system will be installed.
