What is the largest offshore gas platform in the world?

• A. Troll A
• B. Ekofisk
• C. Gullfaks C
• D. Brent Alpha

Answer: (A)

The biggest offshore platform is Troll A. It’s a gravity-based concrete structure built to produce gas from the Troll field in the North Sea, and what sets it apart is its size and mass—the tallest offshore platform ever constructed. Its massive hull rests on the seabed and supports a deck that rises far above the water, making it vastly larger than other platforms. The other options—Ekofisk, Gullfaks C, and Brent Alpha—are substantial, but they are smaller in overall dimensions and are mostly oil platforms, not matching Troll A’s enormous size.
