A tender has been launched for electrical installation within the planned €7 billion, 18km Fehmarnbelt immersed road-rail tunnel between Germany and Denmark.

As part of what will be a contract worth around €750 million (US$913 million), the winner must set up a renewable energy centre for its work. The tender will close and a decision made by the end of the year, work to start in 2022 or 2023.

Installation will include power for an electrified railway  that will run between beside the two the traffic lanes, ventilation, lighting, safety-emergency-monitoring systems, emergency doors, fire extinguishing systems, drainage, cable-pipe and various control systems.

The Fehmarn Belt is a strait between the German island of Fehmarn and the Danish island of Lolland. The tunnel will replace a ferry service from Rødby and Puttgarden. The project’s approval process was bogged down over environmental issues, especially within the German state of Schleswig-Holstein in which the southern end of 18km immersed tunnel will surface

Meanwhile, Femern Link Contractors started dredging and filling work last month for a works harbour in Rødbyhavn, as well as a tunnel portal on Lolland. A video of the dredging and earthworks is available here.

A Rambøll-Arup-TEC consultancy joint venture is engaged in a client consultancy services contract with Femern. The joint venture has also worked on other landmark infrastructure projects, including the Øresund Tunnel in Denmark, the City Tunnel in Malmö, Sweden, the Medway Tunnel in England, as well as underground rail systems in Amsterdam and Copenhagen.

COWI is carrying out the detailed design of the tunnel (north tunnel section, south tunnel section, and ramps & portals). Meanwhile, SWECO is handling the design for the dredging and reclamation work.
