Well putting my 2 cents in here but if they are going for economic then blowing up a tanker while it's coming into port would shut down all the traffic for quite a while.
But if they are looking to rack up a death toll as well as economic then I would think they would go for hitting the storgae facilities. Multiple targets at once could be pretty big.

Yep...Wonder if these particular tankers venture up the Mississippi?
