en.Wedoany.com Reported - SPIE Global Services Energy has recently been awarded a contract by Seaway7 to provide termination and testing services for inter-array cables at the Bałtyk 2 and Bałtyk 3 offshore wind farms in Poland. The project will be executed by the group's specialized high-voltage wind team, SPIE Wind Connect, with offshore operations scheduled to commence in the second quarter of 2026.
The related work primarily revolves around the 66 kV inter-array cable system, connecting wind turbines to the offshore substations. Each wind farm is designed with 10 turbine circuits, with each circuit comprising 5 wind turbine generators. The most distant units within a circuit are connected via 400 mm² cross-section cables, while 1000 mm² cables are responsible for transmitting the entire circuit's output to the offshore substation.
The Bałtyk 2 and Bałtyk 3 projects are being developed by Equinor and Polenergia in the Polish exclusive economic zone of the Baltic Sea. They will feature a total of 100 Siemens Gamesa SG 14-236 DD wind turbines, with a combined installed capacity of 1,440 MW. Seaway7 secured the engineering, procurement, construction, and installation contract for these two wind farms in 2023, covering approximately 200 kilometers of 100 66 kV inter-array cables.
The sites are located approximately 37 km and 22 km off the coastlines of Ustka and Łeba, respectively, with offshore wind construction having commenced earlier this year. Construction activities in 2026 include the installation of 100 monopiles, transition pieces, offshore substation components, submarine cables, and associated infrastructure. Turbine installation and offshore substation outfitting are expected to begin in 2027, with first power generation occurring the same year, followed by full commercial operation in 2028.
