Posted on 4 March 2016

dws-boskalis-fehmernbelt-tunnel-impression-770pxDanish planning company Femern has announced its intention to award a contract for dredging and reclamation related to the construction of the Fehmarnbelt tunnel to the Fehmarn Belt Contractors consortium.

Besides Royal Boskalis, this consortium includes Hochtief, Ed Züblin and Van Oord.

The Fehmarnbelt tunnel is to connect Denmark and Germany with a 18 km long immersed tunnel link, carring a four-lane motorway alongside a twin track-electrified railway.

The total budget for the Fehmarnbelt link construction is 6 billion euro and the value of the contract to Boskalis is 300 million euro.

Femern is a subsidiary of the Danish state-owned Sund & Bælt Holding and is charged with preparing the construction of the tunnel.

The Fehmarn tunnel is to link the German Fehmarn island and the Danish Lolland island by 2024.

Longest immersed road and rail tunnel
The Fehmarnbelt Fixed Link will connect Denmark and Germany and will be the world's longest immersed road and rail tunnel.

The fixed immersed tunnel link across the Fehmarnbelt will be more than 18 km long and carry a four-lane motorway alongside a twin track-electrified railway.

The Fehmarnbelt Fixed Link tender consisted of four contracts: the tunnel north, the tunnel south, tunnel dredging and reclamation and the tunnel portals and ramps.

Preferred bidder
The Fehmarn Belt Contractors consortium is the preferred bidder for the tunnel dredging & reclamation contract. The contract is conditional to obtaining the outstanding environmental permits that have yet to be issued by the German authorities.

These permits are not expected to be issued before 2017.

Tunnel trench in seabed
The activity scope for Boskalis together with Van Oord includes the dredging of a tunnel trench in the seabed over a distance of 16 km with the use of various types of dredging equipment including trailing suction hopper dredgers, backhoes and grab dredgers.

The dredged material will be reused to create a new recreational nature reserve area on the Danish side of the Fehmarnbelt.

The consortium will also construct a new working harbor where the tunnel contractors will construct a tunnel fabrication yard where the tunnel sections will be cast before being floated out to sea for installation.

Specialized joint venture in immersed tunnels, Tunnel Engineering Consultants (TEC) provided input to the design and tender preparation for the tunnel. TEC is a joint venture made up of Dutch consultancy firms Royal HaskoningDHV and Witteveen+Bos.
