An argument can be made against double hull tankers. I've heard it said that the space between the hulls can get filled with explosive gases, raising the risk of catastrophy. Perhaps filling the space with some sort of foam could solve that problem.
Double hull tankers may cut the risk, but they don't eliminate it. There was a large spill involving a double hull tanker about 8-10 years ago in Europe.
