The Akademik Tryoshnikov, a Russian diesel-electric research vessel, is the flagship of the Russian Polar Research Institute. It was built at the Admiralty shipyard in St. Petersburg. It has a complex diesel-electric propulsion plant, consisting of three Wärtsilä engines, two 6,300 kW and one 4,200 kW, which drive high-voltage Alconza generators.

Chilean Navy polar vessel currently under construction at the Asmar Shipyard in Talcahuano. She has a total power of 14.5 MW in her diesel-electric propulsion plant, with main propulsion engines supplied by Alconza and directly coupled to the propeller.
- 2 synchronous generators of 5040 kVA, 690 V, 50 Hz @1000 rpm (LV)
- 2 synchronous generators 2030 kVA, 690 V, 50 Hz @ 1000 rpm (LV)
- 2 horizontal asynchronous drive motors 4500 kW, 17 Hz, 690 V @123 rpm (LV)
- 1 vertical asynchronous motor 2000 kW, 720 V, 50.5 Hz @750 rpm (LV)
This vessel will replace the “Oscar Viel” vessel, currently the Chilean Navy’s icebreaker, and will focus on logistical support activities in the Antarctic Polar Circle. It will be equipped with hydroacoustic equipment for geological and oceanographic research, and will be capable of conducting search, rescue and towing activities.
