Dutch offshore contractor Boskalis has won two deals 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, awarded by a joint venture between PGE Polska Grupa Energetyczna and Ørsted, were described as ‘large’ by the company which means that the combined value was over €300m (322m).
The project scope comprises the transportation and installation of 107 array cables with a total length of more than 150 kilometres in addition to four 275 kV export cables with a total combined length of nearly 300 kilometres.
Furthermore, Boskalis will carry out seabed preparation activities including the levelling of the seabed, pre-trenching and the removal of boulders. Upon completion of the cable installation activities, Boskalis will protect and stabilize the cable protection systems with the placement of rock.
Preparatory works will commence in 2025 and the transport and installation activities will commence 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 in the Polish section of the Baltic Sea some 40 kilometres off the coast of Poland between Leba and Ustka and will be the country’s largest renewable energy project to date.
