Fugro, the Geo-data specialist has finished Fehmarnbelt Tunnel’s nearshore geotechnical investigation. The tunnel will link Germany and Denmark by rail and road and become the world’s longest immersed tunnel.
It has been 10 years that the company is involved on the project, from primary site study work up to the ongoing geotechnical investigation. This latest phase contained geotechnical site characterization of the sub-seabed soil at both tunnel entrances and, on the Danish side, the production facility where the hollow concrete tunnel elements are being created.
Fugro used its Skate 3 jack-up platform; a custom-designed geotechnical spread; and a specialist data-acquisition team to perform core drilling and downhole cone penetration tests. Then, the deducted data were analyzed to show subsurface uncertainty to increase the client’s and the contractor’s ground risk exposure by supplying secured geotechnical design input parameters.
Femern Link Contractors, the consortium constructing the 18km-long tunnel, was the client for the work.
