In modern times, with some major climatic changes, there are certain opportunities opening up in the form of newer and shorter sea routes. For example in China, there has been an emphasis on using the route across the Arctic Ocean to reach Europe and the USA. This was given a thumbs-up after the exploration carried on by the Icebreaker Xuelong. China has seen a very good opportunity to tap the potential of this route formed as a result of the climate change. But it is not only the Arctic which is freezing cold, sea routes also pass through North Atlantic or North Pacific regions. Remember the assignment of freeboards on Plimsoll Lines? Enough said already, you should get a picture already by now as we come to the topic – accumulation of ice on ship.
