Boskalis, a Dutch company that provides dredging and maritime services to the offshore energy sector, has been awarded two contracts for the transportation and installation of export and array cables for the Baltica 2 offshore wind farm off the coast of Poland. The two contracts have a combined value over $322 million. A joint venture formed by PGE Polska Grupa Energetyczna and Orsted is developing Baltica 2.
The project scope comprises the transportation and installation of 107 array cables with a total length of more than 93 miles in addition to four 275 kV export cables with a total combined length of nearly 186 miles. Boskalis will also carry out seabed preparation activities: leveling of the seabed, pre-trenching and the removal of boulders. Upon completion of the cable installation, Boskalis will protect and stabilize the cable-protection systems with the placement of rock. Preparatory works will begin in 2025 and the transport and installation activities will start in 2027.
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 25 miles off the coast of Poland between Leba and Ustka. It will be the country’s largest renewable energy project to date.
