600,000 Tons of Impossible Engineering: Shell's Prelude FLNG

The Shell Prelude FLNG is not a ship. It is not an oil rig. It is a 600,000-tonne beast designed to do the impossible.

In this video, we explore the engineering insanity behind the largest floating structure humanity has ever built. Longer than the Empire State Building is tall and displacing more water than six aircraft carriers, the Prelude sits in "Cyclone Alley" to harvest gas from the ocean floor.

We uncover how it survives Category 5 storms without ever disconnecting, the 1.6 million engineering hours required to build it, and why—after costing $17.5 Billion—Shell says they will likely never build another one.

Correction note:
The brief map animation showing the 475 km distance unfortunately uses the wrong coastline (Tasman Sea / New Zealand area visible). The narration is correct — Prelude is 475 km north-northeast of Broome, Western Australia (Browse Basin). Thanks to viewers for pointing this out!
