Dutch Offshore Contractors (DOC) commenced an intensive loading campaign at Hellenic Cables' Corinth/Soussaki plant in Greece and completed the first transport tranche in early April 2026. The heavy-lift carrier FJORD (IMO 8636740) loaded approximately 200 kilometres of 220 kV HVAC submarine export cable using an advanced dual-spooling operation across three carousels of 9,000 tonnes each, for a total loaded weight of 19,500 tonnes. FJORD departed Vlissingen (Netherlands) on 1 April 2026 bound for Poland, where cables will be offloaded directly onto Jan De Nul's cable-laying vessel Isaac Newton for offshore installation. The shipment forms part of the four 220 kV HVAC export cable package (256 km combined) supplied under the October 2023 consortium contract between Jan De Nul and Hellenic Cables for the connection of Bałtyk 2 and Bałtyk 3 offshore wind farms to shore, developed by the Equinor–Polenergia joint venture. Cable manufacturing is performed at Hellenic Cables' subsidiary Fulgor's Corinth plant. The 2026 offshore construction campaign includes installation of monopiles, offshore substations, and the export and inter-array cable system, with more than 20 specialised vessels engaged.
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.

In January 2026, Equinor and Polenergia began offshore site preparation for Bałtyk 3, launching a subsea rock installation campaign as the first phase of the offshore installation works shared with Bałtyk 2. Specialist vessels started placing more than one million tonnes of rock on the seabed to protect future export and inter-array cables and turbine foundations against waves and currents, providing mechanical protection ahead of main installation activities.
Offshore construction for the Bałtyk 3 offshore wind farm formally commenced in January 2026 as part of the joint Bałtyk 2 and 3 programme. The 2026 offshore campaign, led by Equinor and Polenergia, began with subsea rock installation and will progress to installing 100 monopile foundations with transition pieces, offshore substation components, subsea cables, and other supporting infrastructure at the project site in the Polish exclusive economic zone of the Baltic Sea.
During 2025, manufacturing and delivery of key transmission components for the Bałtyk 2 and Bałtyk 3 grid connections progressed significantly. Tele‑Fonika Kable’s Bydgoszcz plant supplied cables for the onshore section of the connection corridor linking the landfall near Ustka with the new substations and onward to PSE’s Słupsk–Wierzbięcino substation, while Hitachi Energy’s facilities in Łódź produced autotransformers for the onshore power stations in Pęplin. These manufacturing activities underpin the Bałtyk 3 Export system, which will transmit power from the Bałtyk 3 offshore substation into the Polish transmission grid.
In 2025, Equinor and Polenergia carried out offshore site preparation for the Bałtyk 2 and Bałtyk 3 export cable systems, including Bałtyk 3 Export. The work comprised UXO surveys and seabed preparatory works along the offshore cable routes, including boulder relocation using tools such as Helix Robotics Solutions’ i‑Plough under an amended contract with the Jan De Nul–Hellenic Cables consortium, to clear and prepare the submarine export cable corridors ahead of installation.
In 2025, the Polish research company MEWO completed an inspection of the seabed for potential unexploded ordnance and duds in the offshore area for the Bałtyk 2 and Bałtyk 3 wind farms, as part of preparations for upcoming offshore construction and export cable installation.
In October 2025, the Bałtyk 2 and Bałtyk 3 project reported significant fabrication milestones for offshore infrastructure components at multiple facilities across Europe. Key achievements included setting the first transition pieces upright at the fabrication yard, completing initial production of one of the two offshore substation topsides and beginning its outfitting phase, and completing fabrication and assembly of the jacket support structure for one of the offshore substations. These works were carried out in parallel at facilities in Poland, Belgium, the Netherlands and the United Kingdom. The offshore substations are critical components of the Bałtyk 3 Export transmission system, housing the 220 kV HVAC switchgear and transformer equipment that will aggregate power from the Bałtyk III wind farm's inter-array cables and step it up for transmission via the two 220 kV submarine export cables to landfall near Ustka. Progress on these fabrication milestones confirms the project is on track for offshore installation commencing in 2026.
On 31 July 2025, Equinor and Polenergia reported signing amendments to their existing contracts with the Jan De Nul Group and Hellenic Cables consortium for the Bałtyk 2 and Bałtyk 3 projects, extending the export cable EPCI scope. Under the amendments, Jan De Nul, with Helix Robotics Solutions as subcontractor, will clear boulders from the submarine power cable routes prior to installation by relocating large individual boulders with an ROV grapple and removing dense clusters using Helix’s specialised i‑Plough unit, thereby preparing the offshore export cable corridors for safe installation, including those of the Bałtyk 3 Export system.
Onshore construction for the Bałtyk 3 offshore wind farm, developed by Equinor and Polenergia alongside the adjacent Bałtyk 2 project, started in June 2025.
