I think all we really need is the ones that the bush administration removed.
and I think they need to re-evaluate their emergency responce
systems.
sure pumping oil at this depth can be safe but only if nothing
goes wrong as has been proven.
the Obama Administration as you mentioned didnt remove restrictions or place restrictions as far as I have heard of , before the incident that is , now he has restricted any deep oil drilling.
until they can come up with a better safer way to prevent oil spills at this or similar depths.
look how long the rov's have been down there.
if there was just a simple valve below the BOP then a rov
could have closed the valve the same day.
in the future a manual valve should be there so that a
rov can manualy close the valve.
that is if a oil rig doesnt land on top of the BOP !!!
which is another problem that needs to be addressed.
or upgrade existing BOP's with a manual valve system.
Sounds like the problem's fixing/fixed itself then. Cool. Maybe if this next trick fails they can just leave it. Gas doesn't hurt anyone out there in the sea.
IF the gas stops , then the oil will not come out unless the heavier water drains into the well , pushing the oil up slowly
but considering the temperature at the sea floor , probably never would actually come out of the pipe.
the crude would have too great a viscocity and would get stuck in the pipe.
there is the possibility that the sea floor could break up as
the presures decrease , thereby releasing all of the methane at once.
that is the really scarry part , do we even know the volume of methane we are speaking about?
however methane is one of the worst gasses that cause climate change.
methane naturally seeps up from the sea floorand from lakes and ponds , so the effect of methane on sea life is negligible.
