The Baltic Shipyard (part of the United Shipbuilding Corporation, USC) has installed the main turbogenerators and propulsion electric motors (PEM) on the fifth universal nuclear icebreaker of Project 22220, Chukotka, which is under construction.
Specialists have lifted and installed the port turbogenerator and the central propulsion electric motor on board the icebreaker under construction. The shipyard's shipbuilders have now started installing equipment on the foundations.
USC noted that the propulsion electric motors, weighing about 300 tons each and with a capacity of 20 MW, are key elements of the icebreaker's electric propulsion system. In total, there are three of them on the Project 22220 icebreaker: port and starboard, and central.
Through the shafts, the PEMs transmit torque to the propellers in the underwater part of the stern of the vessel. The total power of the icebreaker on the shafts is 60 MW.
The nuclear icebreaker Chukotka is the fifth vessel of Project 22220, being built at the Baltic Shipyard by order of the Rosatom State Corporation. The vessel was launched on November 6, 2024.
