Construction of the world’s first mile long ship tunnel has been started at Snohetta’s entrance through norwegian coastline, says an article published in DesignBoom.
Project ship tunnel
The project, being first of its kind, was first commissioned in 2016 by the norwegian coastal administration.
The tunnel measures 36 meters wide and 37 meters high. Although a similar ‘rove’ tunnel was built in France in 1927, it accommodated only small barges, measuring only 22 meters wide and 11.4 meters high.
Natural sea conditions
The stad sea is a dangerous stretch with challenging ocean currents and underwater topography.
The resulting complex and unpredictable wave conditions combined with strong wind result in a very demanding part of the coastline. high waves coming from different directions can create critical situations for boat traffic. The waves can stay behind several days after the wind has died down, making sailing conditions difficult even on days with little wind..
Safety measures taken by Snohetta
With its integrated natural and cultural elements, snøhetta’s ship tunnel seeks to avoid becoming a ‘foul intervention’ in the landscape
Stone walls are brought into the design of the entrances, creating slightly sloping terraces. These terraces are built into the stone, carved out of the mountain where the tunnel is created.
The terraces will have a naturally rough form within the precise geometry of the horizontal lines. In addition to creating a link to the area’s cultural landscape, the geometry is also highly beneficial for the structural stability of the portal.
