Cyberattack Halts Construction of Denmark-Germany Fehmarn Belt Tunnel

Construction Halted After Attack

Construction of the road-and-rail tunnel under the Fehmarn Belt strait, intended to connect Denmark and Germany, has stopped following a cyberattack on the international FLC consortium carrying out the work, RMF24 reports. As a result of the attack, workers' identification cards stopped functioning, and vessels, cranes and platforms used for offshore work were immobilized. According to Danish media, construction work has therefore been completely halted.

Consortium and Project Scale

The FLC consortium employs around 2,800 people in total from companies in Denmark, Germany, France, Belgium and the Netherlands, with a significant number of Poles among the workers at the site. The 18-kilometer tunnel is being built from 89 concrete elements, which are transported and connected at sea using digital software. The project's cost is estimated at approximately €7 billion, and its opening was initially planned for 2029, though possible delays had already been reported earlier.

Details of the Attack Being Established

Sund & Baelt, the investor company, confirmed that it is discussing the situation with the contractor. It has not yet been established who exactly is behind the cyberattack or how long it will take to eliminate its consequences. Henning Mortensen, head of the Danish Council for Digital Security, did not rule out a connection between the incident and hybrid warfare. In recent weeks, Danish services have warned of possible cyberattacks from Russia and raised the threat level to high.
