Norway to build world's first ship tunnel at sea

Norway on Wednesday unveiled plans to build the world's first sea tunnel to pass through a mountain, avoiding dangerous waters that intimidated even the Vikings.
Built to bypass the Stad peninsula, a storm-swept area in western Norway, the Stad ship tunnel will be 1.7 kilometres (one mile) long and 36 meters wide, making journeys safer.

"The Stad tunnel for boats will finally be built," said Norwegian Transport Minister Ketil Solvik-Olsen, presenting a comprehensive transport plan for the period 2018-2029.

"The government is now ensuring a safer and more reliable passage of the most dangerous and harsh waters for the transport of goods along the Norwegian coasts," he said in a statement.

The North Sea is roughed up by fierce winds off the peninsula and many ships wait for storms to abate before continuing their journey.

Even the Vikings, who were talented sailors, preferred to avoid the waters, instead transporting their boats by land.

Tunnels for boats exist in other parts of the world, such as the Canal du Midi in France, but the Stad tunnel will be the first to accommodate ships up to 16,000 tonnes for freight transport and passengers, including the iconic Bergen-Kirkenes Coastal Express, which connects the Nordic nation's south and north.

The project is estimated to cost 2.7 billion kroner (295 million euros, $315 million).

It should take between three and four years to build, with work to begin in the first half of the multi-year plan, the government said.

Norway may build the world's first tunnel for ships

Stretching over 15 miles, Norway's Lærdal Tunnel has been the longest road tunnel in the world since it was built in the 1990s.

Now, the country is trying to construct the world's first tunnel for ships — which would see between 70 and 120 vessels per day.

As noted by BBC News, the tunnel started gaining public support in the 1980s, and the Norwegian Coastal Administration (NCA) has since embarked on several feasibility studies to see how it could be realized.

Terje Andreassen, the tunnel's project manager, tells Business Insider that the NCA will submit its findings to Norway's Department of Transport in May 2017. The project would need to be fully financed by the Norwegian Parliament, which has already designated approximately $117 million ($1 billion NOK) for the NCA's research.

If the plans are approved, construction could start as early as 2019, Andreassen says.

The NCA worked with Snøhetta, an Oslo-based architecture firm, to create renderings of what the tunnel would look like. Check them out below.

Stormy weather makes it almost impossible for ships to travel in the area. Vessels often wait for hours or even days before it becomes safe enough to cross, Andreassen says. His team at the NCA is conducting research on the feasibility of building the tunnel.

The Stad Tunnel would allow for safer passage along the sea, Andreassen says. Here's a rendering of what it would look like:

From the north, ships would access the tunnel near the town of Selje. The southern entrance would be through the Molde fjord, where there would also be a new pedestrian bridge.

Norway to build world's first TUNNEL for ships in INCREDIBLE £2.3bn feat of engineering

NORWAY plans to build the world's first ever shipping tunnel in a huge £2.3billion project.

Plans for the Stad Ship Tunnel have been revealed allowing ships to avoid one of the most dangerous coastlines in Scandinavia.

Commercial ships will no longer have to navigate the dangerous fjords but instead will use the mile long tunnel.

The tunnel, which will cross the Stad Peninsula at its narrowest point, will be nearly 150ft tall and 118ft wide.



Diggers will remove about 7.5 million tonnes of blasted rock during construction.

Ships as large as Norway's Hurtigruten cruise vessels will be able to use the tunnel with construction set to start as early as 2018.

The Norwegian Coastal Administration said: "The Stadhavet Sea is the most exposed, most dangerous area along the coast of Norway. The aim of this project is to allow ships to navigate more safely through Stad."

The Norwegian Parliament has earmarked nearly £1billion for the tunnel in its 2014-2013 National Transport Plan.

The Norwegian Coastal Administration estimates the entire project will cost up to £2.3billion in total.

Once complete the Stad Ship Tunnel would be the world's first full-scale ship tunnel of this size.

As well as the tunnel, the project includes plans for a pedestrian bridge to allow tourists to watch the huge ships use the tunnel.

The Norwegian Coastal Administration said: "The Kråkenes lighthouse, just south of Stad, is the meteorological weather station with the most stormy days, which can be anything from 45 to 106 days per year.

"The combination of wind, currents and waves around this part of the coastline make this section a particularly demanding part of the Norwegian coast.

"The combination of sea currents and subsea topography creates particularly complex and unpredictable navigational conditions.

"Very high waves come from different directions at the same time and can create critical situations.

"The conditions also cause heavy waves to continue for a number of days once the wind has died down. This causes difficult sailing conditions even on less windy days.

"Studies in 2000-2001 and 2007-2008 have analysed a number of alternative cross sections and routes for the tunnel.

"The final route has been selected because the Stad Peninsula is at its narrowest point here, and at the same time the waters are sufficiently shielded to allow shipping to use the tunnel in the majority of weathers."

That's just too amazing Otter, wow.
