MarineLog is reporting that a German yard is building two icebreaking rescue and salvage vessels for the Russian Ministry of Transport, to be used by “the Russian State Maritime Rescue Coordination Center (SMRCC) for patrols and rescues on the northern Polar Sea route.” The ships will be 88 m x 18.5 m and will be powered by two 3.5 MW Azipods. The ships are larger but the power is very close to that of the Macknaw (WLBB-30) (73 m x 17.8 m) which uses two 3.4MW Azipods.
We have talked about Azipods before, but if you haven’t seen them before, they are quite impressive in the maneuverability they provide (see the video above). gCaptain reports the contract for the entire propulsion and electric generation system for the two almost 10,000 horsepower ships was $25M. To put this in perspective, the Wind Class icebreakers had 12,000 HP.
A new type of Azipod usable for icebreakers, 1.6 megawatts to 7 megawatts (2,145 to 9,642 HP). http://gcaptain.com/abb-introduces-new-azipod-d-electric-thruster/
This post actually does a better job of explaining how these Azipods are better, simpler, easier to service, and more efficient. http://www.marinelog.com/index.php?option=com_k2&view=item&id=8914:abb-adds-to-azipod-line&Itemid=231

20 megawatts is about 27,000 HP so three of them should provide over 80,000 HP.
