Number one, there's close engagement from the CEO level down to the crew on a ship at every level at least annually. All the companies have what is basically called a “fleet week”, where they get together to discuss issues of safety. That starts right from the top.
There are companies that have reward competitions for new safety aspects. I'll give you a great example. One that came out of that type of culture was called the “draft information system”, DIS. It allows a ship to have a 3-D map of the St. Lawrence River through the seaway in real time. That's available to the master of the vessel on the bridge and also in the corporate office, so not only is it increasing the level of safety of the vessel, it's also effecting more efficiency in transportation in the loading of the vessel.
Those are the types of innovations that happen through that kind of corporate culture.
