Specialists from the Baltic Shipyard of the USC have begun installing shaft lines on the icebreaker Chukotka. The propeller shaft, to which the ship's propeller is attached, was loaded onto the stern. This was reported by the press service of the shipbuilding corporation.
In total, it is planned to install three shaft lines made of carbon steel. The total weight of the shaft with two blades and a hub is 83 tons. The length of the propeller shaft is 13 meters, the side counterparts are 16.5 meters, and the diameter is 840 mm.
The shaft lines installed on the nuclear icebreaker Chukotka were manufactured and tested at the Baltic Shipyard, taking into account the specifics of operation in harsh Arctic conditions, and are capable of ensuring safe operation and maneuverability of the vessel.
The nuclear icebreaker Chukotka is the fifth vessel of Project 22220. It is planned to be launched before the end of this year.
Technical characteristics of the icebreaker:
- Length – 174 m.
- Power - 60 MW (on shafts).
- Width - 34 m.
- Displacement — 33.54 thousand tons.
- Draft — 10.5/9.3 m.
- Reactor unit "RITM-200".
- Crew size — 54 people.
- Service life — 40 years.
The official customer of the Project 22220 nuclear icebreakers is FSUE Atomflot (part of the Rosatom State Corporation).
Earlier www1.ru reported that the new nuclear icebreaker Chukotka received a block of protective shell of the central compartment.
