A TikTok went viral after is showed how oil rigs can dwarf some of the world's most iconic skyscrapers. Oil platforms like the Bullwinkle in the Gulf of Mexico can span over 1,000 feet in length.

They’re enormous. The BP oil rig in the Gulf of Mexico that exploded April 20 was 400 feet by 250 feet—roughly the size of two football fields—with a crew of 130. Some rigs are even larger ...

The rig itself was found on the sea floor about 1,500 feet from the well. The sheen of crude oil and water mix on the surface of the water was still more than 40 miles from shore at its closest ...

Offshore oil and gas drilling has been a contentious issue in California for 50 years, ever since a rig ruptured and spilled 80,000 to 100,000 barrels of crude oil off Santa Barbara in 1969.
