The lead Project 22220 nuclear icebreaker \"Arktika\" has begun escorting the LNG tanker \"Aleksey Kosygin\" — the first Russian Arc7 ice-class vessel built at the Zvezda shipbuilding complex for transporting liquefied natural gas (LNG). The route runs from the waters of Primorsky Krai to the export terminal of the \"Arktik SPG-2\" project on the Gydan Peninsula along the Northern Sea Route (NSR).
Earlier, the nuclear-powered vessel had already ensured the safe passage of the LNG carrier through Arctic waters — from the Zvezda shipyard to the industrial site of \"Arktik SPG-2\".
The icebreaker \"Arktika\" is a universal dual-purpose vessel with variable draft: the minimum operating draft is 8.55 m for operation in the inland Arctic seas, and the maximum is 10.5 m for going out into the open ocean
The power plant includes two RITM-200 reactors with a total capacity of 175 MW, providing up to 60 MW of propulsion power at the propellers. With a length of 173.3 m and a beam of 34 m, the vessel is capable of breaking through ice up to 2.8 m thick at a speed of 1.5–2 knots.
The tanker \"Aleksey Kosygin\" became the lead vessel in a series of 15 icebreaking LNG carriers being built for the \"Arktik SPG-2\" project. The Arc7-class vessel has a reinforced hull with a five-meter \"ice belt\" 46 mm thick and is capable of navigating independently through ice up to 1.8 m thick; however, to guarantee safety in difficult ice conditions, nuclear icebreaker support is used.
