Interesting statement about the March 2005 explosion at the BP refinery.  Any ideas on the cause?  Was it another deferred maintenance issue?  Anyone know how much, if any, production was lost as a result before the hurricanes?  And speaking of deferred maintenance, how did BP go from needing to repair/replace 16 of 22 miles of pipeline requiring the shutting in of 400,000 bpd to only needing to shut in 200,000 bpd?  Was the 400k just a scare?  Did they bow to political pressure not to fix all the pipeline so they could keep production up?  Anyone know how things changed so rapidly?
There are two arms to the pipelines that feed into the main Alaska pipeline south.  BP have been given permission to re-open one of them, which carries about half of the production.  I would imagine, since this is the branch that had the spill in March, that this had already been largely inspected.
There's a lot of good material on the explosion at the Houston Chronicle's website; go to http://www.chron.com/ and search for BP refinery explosion. Basically, it was a poorly managed facility with some outdated equipment.
