The Fehmarn Belt Fixed Link is the longest underwater railway and road tunnel in the world. It is the largest infrastructure project in Denmark and one of the most ambitious in Europe, with a total length of 18 km. The contract, awarded to the Spanish consortium made up of the companies SICE and Cobra, is of the Design&Build type and involves the electromechanical systems of the tunnel’s four tubes (two for road and two for high-speed rail).

SICE is responsible for the Electromechanical, Instrumentation, Control and Automation package, as well as the Control Centre. It will also install its own Centralised Management solution: SIDERA, and a new collaborative methodology, the BIM methodology, will be used.
Thanks to this project, SICE positions itself as a world leader in ITS and Tunnel Systems Management Solutions, and considerably strengthens its presence in the Nordic countries and Northern Europe.

The Fehmarnbelt Tunnel, Denmark’s largest infrastructure project and one of the most ambitious projects in Europe, will link Scandinavia and continental Europe through a green corridor that will reduce the connection between Denmark and Germany to only seven minutes by train and 10 minutes by car.

The Spanish consortium formed by the companies SICE – Cobra was awarded the project for the design and construction of the electromechanical installations of the Fehmarnbelt Tunnel, for a total of around 4 billion DKK, just over 530 million euros. The contract, which is part of a total infrastructure project worth more than DKK 55 billion, involves the construction of an 18km underwater tunnel that will connect northern Germany with Denmark, considerably reducing connection times between continental Europe (Hamburg) and Scandinavia (Copenhagen/Malmö).

The contract places special emphasis on energy efficient solutions and solutions that adapt to the green technologies of the future, ensuring of course that the tunnel is a safe infrastructure for both road and rail users. The tunnel installations as well as the traffic in the tunnel will be monitored 24 hours a day to ensure that any incidents are detected and dealt with.

Constructively, the tunnel will have four tubes, in addition to a service gallery: two for road, each with two lanes plus an emergency lane, and two for rail.

This “design & build” contract includes the design, installation, testing, commissioning and maintenance of the tunnel’s electromechanical systems, with an estimated duration of 6 years. The technological systems included in the contract will have the highest levels of reliability, availability, maintainability and safety and will be framed under the acronym “MEICA” (Mechanical, Electrical, Instrumentation, Control & Automation).
