I'm more familiar with the studies that have tried to assess whether ships are inducing erosion. I have to admit I'm a little less familiar with all the regulatory aspects, so I think I will have to defer on that one, but I will say it's a topic of great interest in Germany, the Netherlands and the United States. There are studies on the Savannah River in Georgia. The national research institute in Germany has set up its own lab to study this issue. Certainly it's a topic of concern all over the world.
