The Fehmarnbelt tunnel trench dredging project

A fixed and direct transport connection between Scandinavia and Central Europe has been an enduring vision for many decades. This vision is about to be realised with the construction of the Fehmarnbelt Fixed Link, an 18-kilometre-long immersed tunnel between Rødbyhavn in Denmark and Puttgarden in Germany. When it opens in 2029, the tunnel will be the longest immersed tunnel in the world combining a dual railway and motorway connection. This article provides insight into the improved dredging equipment used and the methodology specially adapted and further developed to the project’s requirements.

Marine Works Operations and Environmental Considerations When Building the Fehmarnbelt Tunnel

The Fehmarnbelt Fixed Link connecting Scandinavia and continental Europe will most likely become a tunnel rather than a bridge, but how it will be dredged is still to be determined.

The Fehmarnbelt Tunnel: Regional Development Perspectives

After almost 2 years of extensive study of conceptual designs, the plans for the "missing" transportation link across the Fehmarnbelt from Denmark to Germany are ready to proceed. The present-day ferry takes 45 minutes plus waiting time. The link will take 7 to 10 minutes.

The Øresund Fixed Link: Dredging and Reclamation

To build the 16 km long bridge-tunnel link from Denmark to Sweden requires the dredging of extremely hard layers of limestone, often in extreme weather conditions, with strictly controlled spillage limitations.
