Boskalis has acquired two contracts for the transportation and installation of the export and array cables for the 1.5 GW Baltica 2 offshore wind farm off the coast of Poland.
The two contracts were awarded by a joint venture between PGE Polska Grupa Energetyczna and Ørsted, which are developing the Baltica 2 project.
“For this project, we will deploy two cable-laying vessels, a construction support vessel, a subsea rock installation vessel and a trailing suction hopper dredger ,” Boskalis said.
The work scope comprises the transportation and installation of 107 array cables with a total length of more than 150 kilometers in addition to four 275 kV export cables with a total combined length of nearly 300 kilometers.
“Furthermore, we will carry out seabed preparation activities including the leveling of the seabed, pre-trenching and the removal of boulders,” said Boskalis.
“Upon completion of the cable installation activities, we will protect and stabilize the cable protection systems with the placement of rock.”
Preparatory works will start in 2025 and the transport and installation activities are set to begin in 2027.
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.
