Troll A platform
From Wikipedia, the free encyclopedia
The Troll A platform is a huge platform for production of gas, it is the highest construction that has ever been moved to another position, and is among the largest and most complex engineering projects in history. Built by Norwegian Contractors for Norske Shell, the platform was a televised sensation when it was towed into the North Sea in 1996, where it is operated by StatoilHydro.

Troll A has an overall height of 472 meters and weighs 656,000 tons. It has the distinction of being the tallest structure ever moved by mankind. The platform stands on the sea floor 303 meters below the surface of the sea. The walls of Troll A's legs are over 1 meter thick.
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, in the northern part of Rogaland, to the Troll field, 80 km north-west of Bergen. The tow took seven days. The platform is built of reinforced concrete using the Condeep technology.
Gas rises from 40 wells, and is exported through a number of pipes.
In 2006, the 10th anniversary of Statoil's operatorship of Troll gas production was celebrated with a concert by Katie Melua held in the Troll A platform. As well as entertaining the workers on the rig, the concert set a new world record for the deepest underwater concert at 303 meters.[1]
In 1996 the platform set the Guinness World Record for 'largest offshore gas platform'.[2]
