World’s first ship tunnel Norway.The Stad Ship Tunnel is a proposed canal and tunnel to bypass the Stad peninsula in Selje Municipality in Sogn og Fjordane county, Norway. The peninsula is one of the most exposed areas on the coast, without any outlying islands to protect it from the weather. The section has traditionally been one of the most dangerous along the coast of Norway.
The mile-long, 118-feet-wide tunnel will pass through the narrowest part of the Stad peninsula in western Norway, allowing freight and passenger ships to bypass the stormy, exposed Stadhavet Sea and avoid a highly treacherous part of the Scandinavian nation’s coastline.
Two paths have been proposed: one 1,800 meters (5,900 ft) long from the Eide farm at the inner part of the Moldefjorden through the Mannseidet isthmus to the Kjødspollen (the inner part of the Vanylvsfjorden), the narrowest but innermost place of the peninsula. The other option is a slightly longer tunnel from the Skårbø farm to the Fløde farm through the central part of the peninsula.
In 2013, the tunnel was included for the first time in the National Transport Plan. 1 billion kr was set aside for it in the budget. The tunnel will be 162 ft (49m) high and 118 ft (36m) wide, able to handle ships of up to 16,000 tonnes (16,000 long tons; 18,000 short tons), large enough for the Hurtigruten coastal express ships. The water will be 12 metres (39 ft) deep in the tunnel. The cost is estimated to be 1.7 billion kr, and construction will start in 2018 and is expected to open in 2023.
The team anticipates it will take three to four years to build the tunnel and cost an estimated $315 million. To create it engineers will have to blast out a huge eight million tons of rock.
The first proposal was in an article in Nordre Bergenhus Amtstidende newspaper in 1874, and shortly afterwards an article in the same newspaper proposed a railway tunnel across the peninsula. The latter would have allowed the boats to be raised onto wagons and to be hauled across, and would cost only half as much.
In 2011, a report by Det Norske Veritas and Institute for Research in Economics and Business Administration for the Norwegian Coastal Administration concluded that a tunnel would not be economical. It looked at two sizes, small and large, which would cost 1,264 million and 2,027 million kr respectively. The report concluded that the utility, including saved waiting costs, for shippers have a present value of 304 million and 314 million kr, respectively, and 67 million and 76 million kr in saved accident costs. A similar report from 2007 concluded that the tunnel would be economical. The Coastal Administration stated that the differences were because of new and better data.
Terje Andreassen is the project manager and he states that construction is expected to start, at the earliest, in 2019.
