As for the construction method of the Fehmarn Fixed Link, the tunnel parts will be prefabricated and fitted into the seabed by a series of movable steel and concrete transverse gates.
Industrias Metálicas Anro will be in charge of producing the second gate of the dry dock where the concrete segments will be manufactured. The gate, 110m long and 750ton, will be an essential element in the assembly of the tunnel components. It will include a movement and sealing system that allows the gate to be lifted and moved to any desired location.
Some 19 million cubic meters of rock and sand are expected to be excavated from the bottom of the Baltic Sea, which will be used to gain ground along the Danish coast.
