For the first time a Gas tanker (Norwegian ship Ob River) will attempt to cross the Arctic during the winter season, a period when previously this was unthinkable in the past as the ocean was frozen over.

The trip via the Arctic will save 20 days travel time on the journey from Norway to Japan. A Russian icebreaker is leading the convoy.
