Baltica 2: 150 km cable corridors ready in the Baltic Sea

Baltica 2 offshore wind farm project entered the next stage of implementation. The preparation of 150 km of routes for internal cables to connect turbines to marine power stations has been completed.

The work carried out in the Baltic thus confirms the maintenance of the schedule of one of the largest offshore elevator investments in Poland.

150 km of cable tracks between turbines

The Boskalis-owned BOKA Falcon unit completed the first phase of the seabed preparatory campaign for laying internal cables in the Baltica 2 project. 150 km of cable corridors have been cleaned and prepared to allow safe connection of turbines to sea stations transformer.

The work included a full sequence of activities: from geotechnical research and the identification of ground conditions, by checking routes for unexploded and unfired, to removing large boulders and making excavations for cables.

No hazardous objects were detected, allowing smooth transition to subsequent stages.

Cleaning and digging under cables

The key element of the operation was clearing routes from boulders with a diameter of up to 2 metres. T-Rex ploughs were used for this. The excavation of cables was then started using the Megalodon plough, which allowed the bottom to be properly prepared for later laying and securing the wires.

The completed part of the campaign concerns internal cables. The next stage will include the designation and preparation of 260 km of routes for export cables that will bring energy to land. The installation will be carried out by cable laying ships Ndurance and Boka Ocean.

Energy from the Baltic to the National Power System

After the sea work is completed, the energy from Baltica 2 will go to the terrestrial transformer station in the municipality of Chochewo and then to the National Power System.

Baltica 2 with a power of approx. 1.5 GW is a joint investment of PGE and Ørsted. This year, the installation of foundations, export cables and marine transformer stations is planned. Launching the farm scheduled for 2027. After putting into operation it will be the largest offshore wind farm in Poland, able to power more than 2.5 million households.

The project clearly enters the phase of intensive installation at sea. For the Polish offshore wind sector, it is a moment of transition from the stage of preparation to the stage of real construction of energy infrastructure in the Baltic.
