Dutch offshore installation services provider Boskalis has clinched two significant contracts for the transportation and installation of export and array cables for the Baltica 2 offshore wind farm, situated off the coast of Poland. The contracts, awarded by a joint venture between PGE Polska Grupa Energetyczna and Ørsted, the developers of the Baltica 2 project, have a combined value exceeding 300 million euros, qualifying them as "large" according to Boskalis.
The project's scope encompasses the transportation and installation of 107 array cables, totaling over 150 kilometers in length, as well as four 275 kV export cables, with a combined length of nearly 300 kilometers. Additionally, Boskalis will undertake seabed preparation activities, including seabed leveling, pre-trenching, and boulder removal. Upon the completion of cable installation, the company will protect and stabilize the cable protection systems (CPS) by deploying rock.
Preparatory work is slated to commence in 2025, with transport and installation activities commencing in 2027. Boskalis plans to employ two cable-laying vessels, a construction support vessel, a subsea rock installation vessel, and a trailing suction hopper dredger for the project. Given the challenging soil conditions in the Baltic Sea, the cables will be installed in a pre-cut trench utilizing the multi-mode Megalodon plow, deployed from Boskalis' construction support vessel, Falcon.
The Baltica 2 offshore wind farm, boasting a total capacity of up to 1.5 GW, is positioned in the Polish section of the Baltic Sea, approximately 40 kilometers off the Polish coast between Leba and Ustka. This project represents Poland's largest renewable energy endeavor to date.
