Rosatom has gotten exclusive responsibilities for the development of the Northern Sea Route and is in full swing with developing new icebreaking vessels, both nuclear-powered and conventional-engined.

«We are reaching the stage where we start using the fleet of port vessels that will serve project Yamal LNG for the next 25 years,» says Vyacheslav Ruksha, Director of Rosatom’s Northern Sea Route Directorate.

«I am confident that the Gulf of Ob will become a center for production of LNG,» he underlines in a press release.

The «Ob» is designed by Aker Arctic and has capacity to break through 1,5 meter thick ice at two knots speed. It is built at the Vyborg Yard outside St.Petersburg.
