Troll Platform

|
Troll Platform is a huge gas platform; one of the largest and most complex engineering projects in history. Built by Norske Shell, the platform was a TV sensation when it was towed into the North Sea in 1996. There it was handed over to Statoil.
It reaches the sea floor, 303 metres below the surface of the Norwegian Sea. Gas rises from 40 wells, and is exported through a number of pipes. Its height is 472 meters and it weighs 656,000 tons. It was the tallest structure ever moved. The base and the deck were built separately (starting in 1991-1992). They were joined while the base was partially submerged. The Troll platform was towed over 200 km from Vats, north Rogaland, to the Troll field, 80 km north-west of Bergen. The tow took 7 days.
