Belonging to the 21900M project, built by Vyborg Shipyard for “Rosmorport” and delivered in 2016, it is the third in its series (Vladivostok, Murmansk and Novorossiysk). It represented the first non-nuclear icebreaker project over the last 30 years.

It is powered by 28 MW in terms of generators, 4 in particular. From those, 18 MW (26,000 hp) are exclusively for propulsion, by means of 2 monoblock motors, capable of reaching 17 knots and working in ice thicknesses of 1.5 meters.

Supply range

  • 4 x 8,482 kVA generators at 6.3 KV
  • 2 x 9000 kW Monoblock motors for main propulsion at 660V
  • 1 x 1000 kW propeller motor for maneuvering propellers

The design of our propulsion motors must take into account strict regulations regarding the shaft design, since the propellers of this type of vessels may come into contact with large pieces of ice, which generates a large over-torque in the shaft line.
