Baltiysky Zavod – Sudostrojenije OJSC (United Shipbuilding Corporation) has laid down the first sections of the superstructure for the lead nuclear-powered icebreaker Arktika (LK-60, Project 22220), the shipyard’s press center says.
The pilot’s cabin is located in the upper part of the superstructure. The accommodation area will have cabins for 75 crewmembers, recreational area, sanitary and utility space. The superstructure weighing some 2,400 t will be placed on the ship following her launching.
Metal-water protection tanks manufactured by Baltiysky Zavod – Sudostrojenije are being prepared for loading. The tanks serve as a foundation for reactor units. Their function is to remove heat generated by the reactor unit and to ensure biological protection of the crew.
Loading of metal-water protection units and construction of the icebreaker’s superstructure are important steps in construction of the ship before she is launched in May 2016. The degree of the Arktika readiness is 30%.
The LK-60 icebreaker of project 22220 Arktika, the first icebreaker of the new generation, will be the world’s largest and most powerful icebreaker.
