There are two things. First, if you talk to any container ship operator right now, shipowners will tell you that we're not going to use any Arctic route for our container ships as long as it's a seasonal operation; we have scheduled services set up, with time-specific departures and arrivals, and we're not going to change that system as long as it's a seasonal access to the Arctic.
The other point of view is that maybe it makes sense to have transfer points: for example, conventional container ships would operate to Iceland, transfer to an icebreaking container ship that would go across the pole, and then transfer again at, say, Dutch Harbor, Alaska, to a conventional container ship.
So there are two different points of view as to how container ships might react to this opportunity, but the conventional wisdom right now is that it will not happen with the container ship operators that are operating right now.
