We're drawing from best and not so best practices. That's right. We are learning from both sides.
You're looking for number three. I'd say that it is safety, pipeline safety in particular.
In my opening remarks I talked about the focus on management systems. Our recent study on offshore drilling revealed that the best way to promote safety on platforms, and the best way to protect the environment and ecosystems, is with the concept of a safety culture. Now, it may sound a little soft to talk about culture. It is a difficult concept to describe. But safety culture is driven by rigorously documented management systems that start from the top of the organization. People know about them. Safety culture is what people do when nobody else is watching. I think we can continue to progress on that.
