A tunnel for the LNG terminal in Dunkirk

30 September 2011 - New contracts - France

Within the framework of the methane gas terminal project in Dunkirk (north of France), the consortium composed of CSM Bessac (leader) and Soletanche Bachy, both subsidiaries of Soletanche Freyssinet (VINCI Construction), and Razel has been appointed to build a 5 km-long tunnel.

This structure (internal diameter: 3 m) will enable some of the warm effluent from the Gravelines nuclear power plant to be transported to the terminal‘s pumping station, where it will be used for the regasification of the liquefied natural gas (LNG). The works will take almost 40 months to complete. They will also involve creating a shaft more than 45 metres deep, internal diameter: 16 m.

Reminder: construction of the three LNG storage tanks has been awarded to the consortium led by Entrepose Contracting (VINCI Construction).
