The HDD technology allows for precise drilling below the ground surface – without the need for excavation or interference with the beach or dunes. Each of the four boreholes will be approximately 1,200 meters long and drilled at a depth of 20–30 meters below ground level. The works are being carried out by a consortium of Polish companies: ROMGOS Gwiazdowscy and ZRB Janicki.
“This is a symbolic moment for the entire project – as the subsea cables are brought ashore beneath the shoreline, the offshore part of the investment meets the onshore part,” said Ulrik Lange, Project Director for Baltica 2 at Ørsted. “Thanks to the use of HDD technology, we can connect these two areas in a way that is safe for the environment and almost invisible from the beach.”
“The start of HDD drilling in Choczewo is another important step in the implementation of the Baltica 2 project. It is the least invasive method of cable line installation and does not require any beach closures during construction. This method is safe and performed at a significant depth, which allows us to carry out the works while respecting the landscape and the natural environment,” said Bartosz Fedurek, CEO of PGE Baltica.
After the drilling works are completed – planned for the turn of 2025 and 2026 – installation of the export cables will begin. These cables will deliver the electricity generated by the wind turbines to the mainland.
