Key milestones have been reached in the production of components for the Bałtyk 2 and Bałtyk 3 offshore wind farms, developed by Equinor and the Polenergia Group. At the premises of the supplier, Smulders, the first transition pieces have been erected, the assembly of the jacket support structure for the offshore power station platform has been completed, and its main part (topside) has been prepared for further equipping. The Polish branch, Smulders Projects Poland, is supplying auxiliary steel, increasing the country’s contribution to the project. The installation of components at sea will begin in spring 2026.

The initial positioning of the transition pieces (TP) in a vertical position is a key stage of production, enabling verification of geometry, precision and quality of workmanship. A total of 100 TP sets will be produced, which, after being equipped with secondary steel, will be transported to the installation port, where they will await further transport and assembly at sea. The secondary steel components are manufactured and supplied by the Polish Smulders plants in Żary, Niemodlin and Łęknica, which significantly increases the domestic contribution to the project.

The preliminary production of the main part (the topside) of one of the two offshore power stations has also been completed and prepared for further equipping. Its weight exceeds 3,500 tonnes. At the same time, the production and assembly of the jacket support structure on which the platform will be mounted has been completed. The structure itself weighs almost 3,500 tonnes and has impressive dimensions: over 40 metres in length and width and over 50 metres in height.

After connecting both elements – the superstructure and the support structure – a structure with a height of nearly 100 metres and sides over 40 metres wide will be created. The total weight exceeds 7,000 tonnes, which corresponds to the weight of 280 fully loaded lorries, which, if lined up one behind the other, would take up over 4 kilometres of road.

Smulders’ plants in Poland, Belgium, the Netherlands and the United Kingdom were involved in the production of these elements, working in parallel. A significant part of the superstructure components was manufactured in Poland.

Smulders is responsible for the design and construction of two complete offshore substations – both superstructures and support structures. In a consortium with Sif, it is producing all transition pieces for the Bałtyk 2 and Bałtyk 3 offshore wind farms. The Bałtyk 2 and Bałtyk 3 offshore wind farms, jointly developed by Equinor and Polenergia, will have a total capacity of 1,440 MW. This will enable them to supply green energy to over 2 million households in Poland and significantly support the country’s energy transition. The first electricity from the farms will flow in 2027, and their commercial operation will begin in 2028.
