The outer cross-sectional dimensions are 8.6 m by 38.8 m, enclosing two railway tubes, two motorway tubes, and a central escape and installation gallery. The elements are placed in a pre-dredged trench, and founded on bedding sand. All 20 tunnel elements are fabricated in a purpose-built casting yard at the Nordhavn area of Copenhagen harbour. The transportation distance to the tunnel site is 20 km. The towing configuration is with two leading tugs and two assisting tugs, i.e. one at each corner of the element.
Figure above indicates locations of casting yard, tunnel site and towing route.
The total duration of a towing and element immersion is expected to last up to 36 hours. The planning of the transportation and installation of tunnel elements requires a wealth of knowledge about the current conditions in resund. This is just an abstract of the application summary.
