I'll give it a shot.
With respect to the insurance, the insurance doesn't per se prevent the event. What it does is prevent challenges after the event when it comes to who pays for cleaning up and what have you. There's much in the legislation that does that, starting with the efforts the government will be able to make to pursue responsible vessel management—not only the prohibition on abandonment, but also the ability to provide notices that a vessel owner needs to act to address a challenging situation and the ability to follow up if the vessel owner does not take the action that's requested in order to address a potential hazard. Those are all the things that contribute to preventing incidents.
This legislation really is kind of like bookends around an incident. It lays out a number of requirements and actions that the government can take to prevent an incident from happening, and also to make it easier to deal with the incident after the fact in terms of identifying the lead role of the Coast Guard, for example, in assessing hazards related to an incident, who pays, etc. From that perspective, there's quite a lot in the bill with respect to prevention.
