Deepwater Horizon - Transocean Oil Rig Fire

Not trying to derail the thread, but I’d like some opinions regarding the fighting of the fire. (I’m no expert regarding fire on marine vessels)

If the first-responder boats had not embrittled the steel (cold water on super hot steel) is it even remotely possible that the DWH could still be floating today?

Obviously if the rig were still floating we’d be in a MUCH better place.

Surely the derrick would have melted. But with most of the heat radiating up, is it plausible that the hull would still have water-tight integrity?

Any thoughts from the experts???

Thanks.
