Boskalis has acquired two contracts for the transportation and installation of the export and array cables for the Baltica 2 offshore wind farm off the coast of Poland. The two contracts have a combined valuea value of more than EUR 300 million.
The contracts were awarded by a joint venture between PGE Polska Grupa Energetyczna and Ørsted, which are developing the Baltica 2 project.
The project scope comprises the transportation and installation of 107 array cables with a total length of more than 150 kilometres. Also included are four 275 kV export cables with a total combined length of nearly 300 kilometres. Furthermore, Boskalis will carry out seabed preparation activities including the leveling of the seabed, pre-trenching and the removal of boulders.
Upon completion of the cable installation activities, Boskalis will protect and stabilise the CPS (cable protection systems) with the placement of rock. Preparatory works will commence in 2025 and the transport and installation activities will commence in 2027.
Five vessels involved
Boskalis will deploy two cable-laying vessels, a construction support vessel, a subsea rock installation vessel and a trailing suction hopper dredger. Due to challenging soil conditions in the Baltic Sea, the cables will be installed in a pre-cut trench using the multi-mode Megalodon plough deployed from Boskalis’ construction support vessel Falcon.
The Baltica 2 offshore wind farm with a total capacity of up to 1.5 GW is located in the Polish section of the Baltic Sea approximately 40 kilometres off the coast of Poland between Leba and Ustka and will be the country’s largest renewable energy project to date.
