Im no epa person nor a oil spill expert but it seems they are having bouy issues of coming apart and so on. Just an idea for the pass s to keep this out why cant we use empty barges tied end to end to block off the pass and also line them on the gulf side with bouys. the barges are deep enough and tall enough to stop the flow and can be skimmed into these barges. Also the barges will act as a wall for the bouys not to have as much stress and come apart.Tugs could help hold the barges in place as well as anchors. Just a thought is all so guys dont kill me on this Im sure we all have ideas.
