1) tons of experience in deep sea work
2) a pretty good idea of the situation (which the rest of us mostly lack)
3) a very large budget and an inventory of resources at their disposal
4) are far from stupid.
So if this is going to be solved in the short term I doubt it will be an outsider.
Occasionally outsiders do come up with great solutions, one I remember was the jet engine strapped to a tank to blow out the gulf war fires. That was sheer genius.
