Nordoya Subsea Tunnel
Faroe Islands

The 6.2 km Nordoya subsea tunnel opened on 29th April, 2006 in the Faroe Islands, three months ahead of schedule. This is a single-tube dual-lane tunnel, the longest in the Faroe Islands, connecting Leirvik on Esturoy with Klaskvik on Bordoy, the most northerly islands. At its deepest point, the tunnel runs 150 metres under the sea level. The Faroes are an archipelago in the north Atlantic ocean between Scotland and Iceland, administered by Denmark. In the fall of 2003, a contract was signed with a joint venture of NCC and local partners J&K Petersen Contractors and Byggitek. Construction began in Leirvik on 18th December, 2003 and in Klaksvik on 20th April, 2004. The tunnel holed through on 25th June, 2005. Visit www.ncc.dk The key element for such a short construction time was the principle of sectional completion of the tunnel. This implied that sections behind the tunnel face of approximately 500 metres each had to be subsequently completed, including the permanent roadworks (drain pipes, cable canals, etc. and one layer of asphalt). Permanent rock support was also determined for each section so that the contractors could install the permanent rock support at any time they preferred. The DKK405 million Nordoya (north island) tunnel is the second subsea tunnel of the Faroes after the Vaga tunnel, built at a cost of DKK302 million. A third tunnel is now planned, the 12 km-long Sandoy tunnel, that will link Gamlaraett on Streymoy island, Hestur island and Skopun on Sandoy (south island). This will be one of the world's longest subsea tunnels ever built. Geoseismic surveys of the seabed are under way. There are special requirements for ventilation and pumping stations that have to be met when building a tunnel of such length. Construction of the Sandoy tunnel will take approximately 5-6 years.

More About Faroe Islands

Location and size Situated in the heart of the Gulf Stream in the North Atlantic at 62°00’N, the Faroe Islands lie northwest of Scotland and halfway between Iceland and Norway. The archipelago is composed of 18 islands covering 1399 km2 (545.3 sq.miles) and is 113 km (70 miles) long and 75 km (47 miles) wide, roughly in the shape of an arrowhead. There are 1100 km (687 miles) of coastline and at no time is one more than 5 km (3 miles) away from the ocean. The highest mountain is 882 m (2883 ft) above sea level and the average height above sea level for the country is 300 m (982 ft).   Climate The weather is maritime and quite changeable, from moments of brilliant sunshine to misty hill fog, to showers. The Gulf Stream encircling the islands tempers the climate. The harbours never freeze and the temperature in winter time is very moderate considering the high latitude. Snowfall occurs, but is shortlived. The average temperature ranges from 3°C in winter to 11°C in the summer. In sheltered areas, the temperature can be much higher, but the air is always fresh and clean no matter what the season.   Population The population is 48.520 (1st April 2008). About 19,400 people live in the metropolitan area which comprises Tórshavn, Kirkjubøur, Velbastaður, Nólsoy, Hestur, Koltur, Hoyvík, Argir, Kaldbak, Kaldbaksbotnur, Norðradalur, Syðradalur, Hvítanes, Sund, Kollafjørður, Signabøur and Oyrareingir, while about 4,700 people live in Klaksvík, the second largest town in the Faroe Islands.   Form of Government Since 1948, the Faroe Islands have been a self governing region of the Kingdom of Denmark. It has its own parliament and its own flag. It is not, however, a member of the European Union and all trade is governed by special treaties.   Languages Spoken Faroese is the national language and is rooted in Old Norse. Nordic languages are readily understood by most Faroese, and English is also widely spoken, especially among the younger people.   Religion Religion plays an important part in Faroese culture and over 80% of the population belong to the established church, the EvangelicalLutheran. 10% of the population belong to the Christian Brethren (Plymouth Brethren).   Industry The fishing industry is the most important source of income for the Faroes. Fish products account for over 97% of the export volume. Tourism is the second largest industry, followed by woollen and other manufactured products.
