SPIE Global Services Energy has been awarded a contract by Seaway7 to provide inter-array cable termination and testing work for the Bałtyk 2 and Bałtyk 3 offshore wind farms in Poland.
The work will be carried out by SPIE Wind Connect, the group’s specialist high-voltage wind energy business unit, and the offshore campaign is scheduled to commence in the second quarter of 2026.
Under the contract, SPIE Wind Connect will terminate and test 66 kV interconnected cable systems connecting wind turbines to offshore substations. Each wind farm will contain ten turbine chains, each housing five wind turbine generators.
According to the company, the offshore turbine in each cascade will be connected using 400 mm² overlapping cables, while 1,000 mm² cables will transport the entire cascade outlet to the offshore substations.
The Bałtyk 2 and Bałtyk 3 plants, developed by Equinor and Polenergia in the Polish Baltic Sea exclusive economic zone, will include 100 Siemens Gamesa SG 14-236 DD wind turbines, with a total capacity of 1,440 MW.
Seaway7 was awarded a contract for two wind farms in 2023, covering engineering, procurement, construction and installation (EPCI) work for 100 66 kV cables, approximately 200 km long.
Offshore construction at the project site(s), located approximately 37 and 22 kilometers from the coast near Ustka and Lipa, began earlier this year. The 2026 construction campaign will include the installation of 100 monopoles, transition pieces (TPs), subsea substation components, submarine cables and supporting infrastructure.
The installation of wind turbines is scheduled to begin in 2027, along with the equipping of marine substations. The first electricity from offshore wind farms is expected to be generated in 2027, and full commercial power production is scheduled for 2028.
