Norway is set to embark on a groundbreaking project to construct the world’s first ocean ship tunnel, with an estimated cost of £671 million. The Stad Ship Tunnel will connect Moldefjord to Kjødepollen on the country’s west coast, spanning a distance of 1.7km (1.06 miles) with additional entrance structures extending to 2.2km (1.4 miles).
The decision to invest in this ambitious project stems from the need to provide a safe passage for vessels navigating the hazardous Stadhavet Sea, known for its extreme weather conditions that pose risks to maritime traffic. The tunnel aims to offer a secure alternative route, reducing delays and enhancing safety for passenger ferries, fishing fleets, and cargo ships.
Originally approved by the Norwegian parliament in 2021 but later postponed due to cost concerns, the project has now been resurrected following a revised budget approval. The Norwegian Coastal Administration is currently evaluating bids from contractors, with plans to commence major excavation and blasting in the near future.
The tunnel, designed to accommodate large ships weighing up to 16,000 gross tonnes, will be free for all traffic, unlike the Rogfast road tunnel. It is expected to enhance Norway’s shipping industry and facilitate smoother transportation of goods, such as salmon exports from Trøndelag. Authorities anticipate that the tunnel will contribute to the region’s economic growth and mitigate risks associated with inclement weather conditions during maritime journeys.
