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.

Fehmarnbelt: A green link between Germany and Denmark

To connect Scandinavia with Germany, the world’s longest immersed tunnel will be built. The Fehmarnbelt will close a major gap in the European transport network while fostering the development of new nature and recreational landscapes.
