Investors PGE Polska Grupa Energetyczna and Ørsted have commenced preparatory works directly preceding the construction of the Baltica 2 offshore wind farm. The Olympic Electra vessel is already operating in the area of the future investment, carrying out the process of relocating boulders and other seabed obstructions. To ensure the wind farm construction on the Baltic Sea proceeds correctly and safely, the investor must move approximately 10,000 objects of various sizes.
The works aim to clear the seabed for the future farm infrastructure – both at turbine locations and along the route of future export cable installation. The process related to preparing the seabed for farm construction will continue until early 2026.
The vessel has been equipped with a specialized boulder removal toolkit, including a dedicated boulder picking spread supplied by Utility ROV Services (UTROV). This technology enables the safe relocation of boulders and other objects with diameters up to 3 meters lying on the seabed, including old nets, steel cables, or pieces of wood.
The ongoing preparatory works at sea represent the final stage before the construction phase begins. The boulder relocation operation has a direct impact on the safety and efficiency of subsequent stages – the installation of foundations and other underwater infrastructure elements.
Several dozen crew members are directly involved in the entire process, not counting vessel operations, investor supervision, and specialist teams that participated in seabed reconnaissance during the research phase.
The cleared area will enable the planned installation of scour protection systems and foundations in 2026, as well as inter-array and export cables in 2027. The contract with UTROV was signed in 2025, and the equipment used has been deployed in similar seabed clearance operations for offshore projects across Europe.
Baltica 2, developed jointly by PGE and Ørsted, is planned to achieve up to 1.5 GW capacity upon commissioning scheduled for 2027, enabling the supply of green energy to approximately 2.5 million Polish households.
The commencement of preparatory works on Baltica 2 represents a key moment for the development of offshore wind energy in Poland and the Baltic region. This project is part of a broader strategy for decarbonizing the Polish energy system and achieving climate neutrality goals. Offshore wind farms in the Baltic Sea could become a pillar of Poland’s energy transformation, utilizing rich wind resources and contributing to the country’s energy independence from fossil fuels.
