1,200 kilometers of Dillinger steel sunk
Langeled, at 1,200 kilometers the world's longest submarine pipeline, will carry natural gas from Nyhamna, in Norway, via the Sleipner distribution station in the North Sea, to Easington, in North-East England. The gas originates from the Ormen Lange field off the Norwegian coast. Langeled consists for the most part of heavy plate supplied by Dillinger Hütte GTS, and if the very tonnage presents a challenge, the boundary conditions are an even greater one.
The pipes must be installed at depths of down to 900 meters, a task possible only with the assistance of submarine robots. Langeled, when completed, will handle up to 70 million cubic meters of gas daily, and up to 8,000 cubic meters of condensate, meeting the heating needs of around ten million UK residents.
