Troll A: The World's Largest Movable Structure and Engineering Marvel
Discover Troll A, a remarkable engineering feat and the largest movable structure ever built. Located in the North Sea off the coast of Norway, this natural gas production platform stands on a gravity-based concrete structure that extends 369 meters (1,211 feet) below the sea. Installed in 1996, Troll A is anchored to the seabed and supports natural gas extraction from the Troll gas field, one of the world's largest.
