The tanker Perserverance left the port of Murmansk on June 29, bound for the port of Ningbo (China), the Ministry of Transport said.
The ship will deliver to the destination port 60,000 tons of gas condensate of Novatek.
Atomflot said the tanker has a deadweight of 73,000 tons. This is the first ship of such tonnage that sails on the shipping lane this navigation season.
Two nuclear-powered icebreakers, the Yamal and the Taimyr started yesterday escorting the tanker to the ice edge in the Chukchi Sea.
