I am not even sure about the only SAR being where it is legislated or in the "developed" world.
Gomer would know exactly but there is only very limited SAR cover in the GOM. Exxon are currently drilling 219 miles out and using an ERA 332L for support....but no SAR out there. The USCG couldn't even begin to respond to an emergency that far out in the GOM. Shell and BP are also drilling deep water wells but no SAR there either.
What would happen if a 332L had even a controlled or semi controlled ditching 150-180 miles out in the GOM?
The operators and the oil companies need to get together and fix this problem.
