A tunnel for ships<\/h2>\n\n\n\n
The tunnel will connect Kj\u00f8depollen in Vanylvsfjorden with Moldefjorden near Selje, cutting through the narrowest part of the Stad Peninsula. Including its entrance areas, the full route will stretch about 1.4 miles from one side to the other.<\/p>\n\n\n\n

The opening is planned to stand about 164 feet high and 118 feet wide, with about 108 feet of clearance from the sea surface to the ceiling. That is large enough for vessels up to the size of Norway\u2019s coastal route ships, including Hurtigruten and Kystruten.<\/p>\n\n\n\n
In practical terms, that means ferries<\/a>, cargo vessels, fishing boats, aquaculture ships, and many coastal cruise vessels could sail through a mountain instead of rounding Stad in open water. It is a simple idea, but not a small one.<\/p>\n\n\n\nWhy Stad matters<\/h2>\n\n\n\n
The waters around Stad are feared for a reason. Project materials describe Stadhavet as the most weather-exposed and dangerous sea stretch along Norway\u2019s coast, where wind, currents, and seabed shape can create highly unpredictable waves.<\/p>\n\n\n\n
Kr\u00e5kenes lighthouse, just south of Stad, has recorded many years with more than 100 storm days. Waves can reach about 98 feet and arrive from several directions at once, which is exactly the kind of sea that makes captains wait, sometimes for days, before moving on.<\/p>\n\n\n\n![\"A](\"https:\/\/okdiario.com\/techy\/en\/wp-content\/uploads\/2026\/07\/norway-stad-ship-tunnel-maritime-engineering.jpg\" "\\"\\"")
The Stad Ship Tunnel will provide a protected 1.7-kilometer shortcut, allowing vessels to bypass the treacherous and storm-prone Stadhavet Sea.<\/figcaption><\/figure>\n\n\n\nThat waiting time has a very real business cost.

The climate promise<\/h2>\n\n\n\n
The environmental argument is straightforward. If ships spend less time fighting rough seas or waiting for a safe weather window, they can burn less fuel<\/a>. That\u2019s the compass behind the project\u2019s green pitch.<\/p>\n\n\n\nA report cited by the Stad Ship Tunnel project compared the current outside route with a simulated route through the tunnel under normal winter wave conditions. It projected fuel reductions<\/a> of up to 60 percent for ships around 131 feet long, and about 30 percent for ships around 459 feet long.<\/p>\n\n\n\n
