AFRY has secured a €9.4 million order for the installation of a SCADA system in connection with the construction of the Nordhavn Tunnel in Denmark.

Nordhavn Tunnel is one of the largest infrastructure projects in the Danish capital Copenhagen in decades. The project entails the construction of a 1.4km tunnel across Svanemølle Bay and the construction of a replacement harbour.

SCADA - supervisory control and data acquisition - is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes. It also covers sensors and other devices, such as programmable logic controllers. For road traffic, a SCADA will collect, analyse and visualise data to provide the tunnel operators with information about incidents, technical errors and when to implement safety precautions.

Apart from the SCADA system, AFRY also provides ITS and internal television for the project that is designed to to reduce the number of heavy goods vehicles in the inner city of Copenhagen.

Once finished, the new tunnel will connect the two city areas of Østerbro and Nordhavn, and connect with the existing 600m-long Nordhavnsvej Tunnel that has its own SCADA system.

AFRY, a Danish engineering design and IT solutions company, has worked with the client Danish Road Directorate on various assignments since the 1990’s. The directorate chose to separate the control system from the actual construction project and find an expert in control systems for tunnels. ”It is important that we learn from the lessons made by Copenhagen Municipality when they constructed Nordhavnsvej Tunnel,” said Silas Nørager, project manager at the Danish Road Directorate and responsible for the control system in Nordhavn Tunnel.

“Our focus is to have a fully integrated system that works from day one between the two road stretches. It’s a technically challenging task and then there is the added difficulty that it has to connect with the existing SCADA system in Nordhavnsvej Tunnel. We are very pleased to award the assignment to AFRY,” said Nørager.

Højgaard Denmark and BESIX have the €349.6 million Nordhavnstunnel construction contract that was awarded by the Danish Road Directorate / Vejdirektoratet. The Højgaard / BESIX joint venture will work closely with project management consultancy Niras, electrical contractor Bravida Danmark and engineering services company Jacobs Sverige. The tunnel is expected to be commissioned in 2027.

The 1.4km cut-and-cover tunnel, to be built in sections in-situ, will run from Svanevænget across the Svanemøllehavn harbour (Svanemølle Bay) to Nordhavn. The consortium will cast the tunnel sections in-situ and around 700m will be underwater. It will connect Østerbro with outer Nordhavn and provide easier access to the port area.
