In the Lubiatowo area, the first of four directional drills under the coastline, beach, and seabed has been successfully completed, with no direct impact on areas of high ecological value. This phase of the project paves the way for connecting the Baltic Power offshore wind farm to its onshore substation. The 1.4 km tunnel will house power transmission cables. The drilling was conducted using HDD (horizontal directional drilling) technology.
The completed section is the first of four underground corridors, designed to hold 30-cm diameter cables. This marks the first large-scale use of HDD technology in Poland. Part of the drilling operation took place offshore, utilising divers and a jack-up rig to complete the underwater section. In total, the drilling will result in the extraction of over 8,000 m³ of spoil from all four drills. According to studies commissioned by Baltic Power, the excavated sand is clean and suitable for beach restoration efforts, helping to repair storm damage sustained over the winter.
“In Europe, shoreline crossing drills are typically shorter, and when they are longer, the drill diameter is usually smaller. For Baltic Power, we are undertaking a significant engineering challenge, drilling nearly 1.5 kilometres under dunes, the beach, and the seabed. It’s not possible to drill from just one side, but we are working to ensure minimal environmental disruption,” said Jens Poulsen, Member of the Baltic Power Management Board.
