Those risk assessments are done by a number of organizations, for a number of different reasons.
Certainly when you're talking about petroleum products, the customer is definitely demanding it. It's a very significant vetting process that happens for carriers that ship petroleum products.
From a shipowner's perspective, that risk assessment is done to make sure that the business is viable from both a safety perspective and an economic perspective. It doesn't make any sense if one of those isn't supported.
I think there are other organizations that conduct risk assessments based on anticipation. A large, semi-political regional body called the Great Lakes Commission recently did one on the carriage of petroleum products on the Great Lakes. I think that process—maybe not official by any oversight by a single government agency—is happening in anticipation of increased traffic with petroleum products.
Do we anticipate that there will be more that is necessary? Absolutely, yes. Whenever you're operating with a different type of vessel, a different cargo, or in a different operating environment, it has to happen. It's the culture of the industry to want to do that.
