VINCI through its subsidiary Cobra IS has just signed the contract to equip the Femern tunnel with electromechanical installations. The contract is over DKK 4 billion (€535 million). It focuses primarily on ventilation, lighting and safety systems, plus maintenance for the electromechanical systems into the five tubes of the tunnel (two for highway road, two for high-speed rail, and one for service gallery) over the next six years.

Cobra IS proposed energy-efficient and climate-friendly solutions, which will notably enable the tunnel operations to run with 100% renewable energy. The Femern, the longest road and rail immersed tunnel in the world, is being built 40 meters below the surface of the Baltic Sea. The construction started in 2020.

After its commissioning in 2029, it will link Denmark to Germany in seven minutes by train and 10 minutes by car. Furthermore, VINCI Construction and its partners have been awarded the main civil works design and build contract of the Femern tunnel. In this context, the precast factory construction that will produce the immersed segments of the tunnel is currently in progress.

Moreover, Cobra is currently involved in carrying out electromechanical equipment works for other major infrastructures projects in Scandinavia, such as the Stockholm bypass, the northern and southern extensions of the Stockholm metro and Tingstad tunnel in Gothenburg, Sweden. Last year, Cobra IS won the contract to implement the electrical installations along 23 kilometers of motorway in Norway, including 15 kilometers of tunnels.
