Why do oil rigs at sea have a constant flame burning on top of them? Natural gas? And why couldn’t it be collected as well instead of wasting it?

It’s an emergency fail safe. Natural gas is a pressure pocket that keeps a lot of liquid at bay. If they were drilling and siphoning gas what would happen if the driver failed? The gas would expand and create a massive pressure expanse. It only has one way to go: right to the rig. They burn it to let some escape easily and keep things in check.
