SICE-Cobra awarded contract for Fehmarnbelt sub-sea tunnel project


SICE-Cobra, an international consortium, has been awarded a DKK4bn (£450m) contract for ‘green’ tunnel technology for the 18km Fehmarnbelt sub-sea tunnel that will link Denmark and Germany.

The consortium was awarded the contract by Femern, the planning company behind the tunnel project.

Fehmarnbelt project will be the longest immersed tunnel and the longest underwater road and rail tunnel in the world once complete.

The immersed tube tunnel will feature a four-lane motorway adjacent to two electrified railway tracks linking the Danish island of Lolland with the German island of Fehmarn.

SICE-Cobra consortium comprises Sociedad Ibérica de Construcciones Eléctricas (SICE) of Spain; SICE Tecnología y Sistemas, Spain; Cobra Instalaciones y Servicios, Spain; Moncobra, Spain. It is backed by Cobra’s international offices and SICE’s US, New Zealand, Australia and Nordic offices.

SICE-Cobra will be responsible for the design and installation of electrics across the tunnel, including lighting, ventilation, automation processes and safety systems.

However, this contract does not include the electrification of train tracks, for which tender will be called later this year.

Construction firm Femern intends to operate the tunnel completely on renewable energy. The consortia comes with the ability to provide advanced technology that is carbon neutral as well as energy efficient.

The procurement process began in spring 2021. During the prequalification stage, three consortia gave their initial tenders for negotiation in November.

Following a good negotiating offer from SICE-Cobra, Femern decided to advance directly to the contract award process.

Femern technical director Jens Ole Kaslund said: “This contract is crucial to our ambition for the Fehmarnbelt Tunnel to be the green transport corridor of the future.

“All bidders submitted top-quality tenders which met our requirements for expertise and qualifications, but the chosen consortium submitted the best bid in terms of price and quality.”
