A large tanker carrying liquified natural gas is set to become the first ship of its type to sail across the Arctic.
The carrier named Ob River, which had left Norway in November, has sailed north of Russia and is on its way to Japan.
According to the BBC, the specially equipped tanker is due to arrive in early December and will shave 20 days off the regular journey.
The ship, with an international crew of 40, has been chartered from its Greek owners Dynagas by the Russian Gazprom energy giant.
The report quoted Tony Lauritzen, commercial director at Dynagas, as saying that a key factor in the decision to use the northern route was the recent scientific record on melting in the Arctic.
"We have studied lots of observation data - there is an observable trend that the ice conditions are becoming more and more favourable for transiting this route. You are able to reach a highly profitable market by saving 40 percent distance, that's 40 percent less fuel used as well," Lauritzen added. (ANI)
