Fehmarn Link Tunnel

The Fehmarnbelt link

Client: Femern A/S 

Mermaid Maritime Consulting has provided maritime consultancy for the planning and procedures of the Fehmarn Link project.

The Fehmarnbelt link will be an 18 kilometre long immersed tunnel. It will be the world's longest of its type for both road and rail.

The tunnel will consist of 79 individual elements, each 217 metres long, and 10 special elements with a lower floor for the use of the tunnel operation and maintenance equipment.

A tunnel element weighs 73,000 tonnes. This corresponds to 14,000 elephants.

The amount of steel used in the tunnel is equivalent to about 50 Eiffel Towers.

Up to 3,000 people will be directly employed in building the Fehmarnbelt tunnel.

It will take about 8.5 years to build the Fehmarnbelt link
