Some of the refineries may be underwater. Maybe that should have no effect on bringing them online -- once the water recedes. I know the buildest hurdle is electrical power for refineries. I don't see why they don't build a small electrical generator facility onsite, and just pump diesel into the generator.
One of the refineries near Baton Rouge had trouble getting back online because the power grid was down.
I don't see why they don't produce their own electricity since they probably have diesel storage tanks at most refineries.
But I really don't know...
I just saw this on another thread:
"and a White House statement that half the lost refinery production shut by the storm would be back on line within two weeks."
With the Platation pipeline back up, and the Colonial pipeline at 705 (up to 86% by the end of the weekend), and Shell announcing a major platform is back on line, things should ease rapidly.
I figure a couple of the refineries are going to need a lot of work, and a couple of more a moderate amount - about the equivilent of a turnaround.
