The contractors on the Fehmarnbelt tunnel

The two European contractor consortia, Fehmarn Belt Contractors (FBC) and Femern Link Contractors (FLC), are responsible for the construction of the 18 km long Fehmarnbelt tunnel between Rødbyhavn and Puttgarden.

The contract with the Dutch contractor consortium, FBC, came into force in November 2019. The task includes the dredging work at sea, the establishment of the two work harbours and land reclamation for the new nature areas.

Sund & Bælt entered into the conditional contracts for the construction of the tunnel itself, portals and ramps in May 2020. The contracts are with the FLC contractor consortium and were effective from 1 January 2021.

In May 2022 Sund & Bælt and the European contractor consortium Femern SICE Cobra (FSC) signed the contract for the important task of equipping the Fehmarnbelt tunnel with advanced electro-mechanical installations and technology.

In December 2022 Sund & Bælt and Elecnor signed the contract for building a large transformerstation that will supply green power to the Fehmarnbelt tunnel’s installations and the railway between Denmark and Germany as well as on Lolland.
