The New York Times calls it, “The Biggest Ship in the World (Though It Isn’t Exactly a Ship)”

“It’s called Prelude, and it’s bigger than big. More than 530 yards long and 80 yards wide, it was constructed with 260,000 metric tons of steel, more than was used in the entire original World Trade Center complex, and it’s expected to displace 600,000 metric tons of water, or as much as six aircraft carriers.”

This one is to be anchored in North West of Australia, but if one comes to the US EEZ, it is going to be an incredible Marine Inspection task.
