Terje Andreassen, director of the Stad Ship Tunnel project, said that it was possible to verify the viability of the tunnel navigation in a safe and stable way under different flow and wave conditions.

The Stad Ship Tunnel project, to achieve the construction of the world's first ship tunnel. The test of the tunnel model has already been carried out at the Norwegian Marine Research Technology Institute (Marintek) in Trondheim, the actual dimensions of which are 1.7 km long, 49 m high and 36 m wide. They can sail cargo and passenger ships up to 16,000 tonnes. There were two different models of ships, the "Midnatsol" ro-pax of the Norwegian Coastal Express and a container carrier. Through the tests with the models, researchers have concluded that the ships could sail through this tunnel under the worst conditions without touching any of the walls of the tunnel. The next step will be the verification of experimental data with other tests carried out.

The Norwegian Government approved with a budget of SEK 1.6 billion, about EUR 162 million, the construction of this tunnel in April 2013. The construction of the project is expected to start in 2018 and complete four years later. This tunnel is part of the Norwegian Government's National Transport Plan (2014-2023), with which it aims to transfer 25% of the goods currently going by road to other modes of transport, namely rail and maritime. This project includes the construction of a stanco compartment for each end of the tunnel to perform after its placement the excavation work that will be carried out using drilling and explosion methods at sea level. The watertight compartments will be removed when they complete the excavation work allowing the water to inundate the channel that will be 12 feet, almost 3.7 meters deep.
