The Fehmarn Belt Contractors consortium has won tunnel dredging and reclamation contract for the Fehmarnbelt Fixed Link tunnel project.
The consortium includes Royal Boskalis Westminster (Boskalis), Hochtief, Ed Züblin and Van Oord. The value of the contract to Boskalis is about €300m.
The fixed immersed tunnel link across the Fehmarnbelt will be the world's longest immersed road and rail tunnel, connecting Denmark and Germany. It will stretch over 18km in length, carrying a four-lane motorway and a twin track-electrified railway.
The overall project, estimated to cost DKR45bn (about €6bn), includes four contracts- the tunnel north, the tunnel south, tunnel dredging and reclamation, as well as the tunnel portals and ramps.
The tunnel dredging and reclamation contract is subject to approval of outstanding environmental permits from the German authorities.
The scope for Boskalis and Van Oord will involve dredging of a tunnel trench in the seabed over a 16km distance by using different types of dredging equipment such as trailing suction hopper dredgers, backhoes and grab dredgers.
The dredged material will be reused to create a new recreational nature reserve area on the Fehmarnbelt’s Danish side.
In addition, the consortium will be responsible for building a new working harbour where the tunnel contractors will construct a tunnel fabrication yard.
