Lo Stad Ship Tunnel Norwegian, a futuristic naval tunnel project over 1600 meters long, has finally received the go-ahead. Construction of the tunnel, scheduled for next year, will cross an entire peninsula, allowing ships to bypass Norway's most dangerous sea route.
For Futuroprossimo aficionados: we talked about it exactly three years ago, when the first preliminary studies were presented. Today the approval: it will be the first “life-size” naval tunnel in the world (in France there was one which could accommodate smaller boats, until its collapse in the 60s). The Stad Ship Tunnel will allow ships to avoid the dangerous waters of the Stad Peninsula by cutting it directly. It will have a height of 50 meters (164 feet) and a width of 36 meters (118 feet). It will reach a total length of 1,7 km (1,05 miles).
The first naval tunnel in the world
In total, it is planned to remove a total of 3 billion cubic meters of rock using a series of barges. Engineers will use a horizontal and explosives drilling technique to remove the upper ceiling section first, then move on to vertical drilling and explosives for the lower section. The entrance and exit of the tunnel will be left partially blocked during this period so that the interior remains dry during the works, then opened when it is time to let the water in.
Based on the letter of assignment, we will now initiate the ownership acquisition processes in the area where the ship's tunnel will be located, as well as put in place a project organization, prepare a tender basis and initiate a tender . There is a lot of work to be done, but we have done thorough studies and planning that will form the basis for the work.Terje Andreassen, manager of the Stad Ship Tunnel project
Once the business opens, an average of 19 ships will pass through each day, with one-way traffic alternating every hour. We have no news on the tonnage of the ships that will pass through the tunnel. We're not talking about weekend pleasure craft, though - they will be substantial cargo ships, as well as passenger ships.
Assuming everything goes according to plan, the completion of the tunnel is expected by 2026. The budget has increased since the last time I told you about this project and is currently set at NOK 2,8 billion (around € 320 million), excluding taxes.
