A breakthrough at the bottom of the Baltic Sea. 150 km of cable routes for the Baltica 2 farm ready

At the bottom of the Baltic Sea, 150 km of routes have been prepared for internal cables connecting the turbines with marine power stations. This is the first stage of preparing the bottom for laying cable infrastructure for the Baltica 2 offshore wind farm, said representatives of PGE Baltica and Orsted.

The work began with geotechnical research along the planned cable routes. The contractors then checked the area for unexploded ordnance and unexploded ordnance, which was a condition for continuing operations in the cable corridor. No such objects were found in these sections.

The next stage was the removal of large boulders (up to 2 m) from the internal and export cable routes. The specialized BOKA Falcon unit, using a T-Rex plow, cleared cable corridors and prepared a route for trenching for cables.

Excavation using the Megalodon plow began at the end of last year. The seabed was prepared so that the cables could be properly laid and secured after installation. The completed stage included 150 km of routes for internal cables. The next phase of work will include the preparation of export cable routes with a total length of 260 km.

Infrastructure security as a priority

Ulrik Lange, vice president and managing director of the Baltica 2 project in Orsted, emphasized in the announcement that the completion of work on the internal cable routes means the completion of a key stage of preparing the bottom for the connections between the turbines.

This is an important milestone because the quality of excavation and corridor preparation directly affects the safety of the installation and the protection of the cables after they are laid. Now we are focusing on the next section of offshore work, maintaining the pace and sequence of activities in accordance with the project schedule, he announced.

Green energy will flow to Choczew

The president of PGE Baltica, Bartosz Fedurek, noted that the work preparing the bottom of the Baltic Sea for the installation of foundations and laying cables is well advanced.

“After creating corridors enabling the laying of cables connecting the turbines, contractors move on to preparing routes for the power output cables. They will soon be connected to the land section of the infrastructure. Thanks to this, after the Baltica 2 farm is put into operation, the electricity produced at sea will go to the onshore transformer station in the Choczewo commune, and then to the National Power System,” he said.

The largest farm in Polish waters

Baltica 2, after its planned launch in 2027, will be the largest offshore wind farm built in Polish waters of the Baltic Sea. Its capacity will be approximately 1.5 GW, which will power approximately 2.5 million households in Poland with green energy. (PAP)
