Russians Building More Icebreakers

MarineLink reports that the Russians have contracted for two new icebreakers.

The icebreakers of Aker ARC 130 A design are about 122 m long overall and have a beam of 25 m and design draft of 8m. The vessels have a diesel-electric power plant and the combined propulsion power of the three azimuth thrusters is 21.5 MW.  (28,820 HP–Chuck)

  1. While the new Russian icebreakers are quite big and can break 7 ft ice, I wonder if the concept (three azimuth thrusters, one in bow and two in stern) could be adapted to a smaller scale and become the next-generation USCG icebreaker/buoy tender for the Great Lakes. Based on recent photographs, the icebreaking vessels in the region are mostly operating in ice channels and brash ice, and the triple-thruster system is superior to conventional alternatives (that is, USCGC Mackinaw) in such ice conditions. Of course, you could go all the way and make the ship asymmetrical like the one that was just successfully tested in the Arctic…

  2. Two Russian 18 MW “Project 21900M” icebreakers were recently tested in the Arctic:

    In total, Russia has built five ships of this type (two “Project 21900”, three “Project 21900M”) in the past years:
    – Moskva (2008)
    – Sankt-Peterburg (2009)
    – Vladivostok (2015)
    – Murmansk (2016)
    – Novorossiysk (under construction; to be delivered in 2016).

    These are the first large non-nuclear icebreakers completely designed and built by Russian shipbuilding companies (one was built by Russian-owned shipyard in Finland). Now that the design has been proven to be feasible (unlike the 25 MW icebreaker that is delayed by several years), I’m quite sure there will be repeat orders, likely with only minor modifications. Most of the existing non-nuclear state-owned icebreaker fleet was built in the 1970s and 1980s, and is due to be replaced in the coming years. This could be the new workhorse for non-Arctic freezing seas as well as Arctic routes during the summer season.

    Anyway, in general this is yet another signal that Russia is actively renewing and developing the icebreaker fleet. These are not one-off designs – they are in serial production.
