Her ice class, ABS A3, indicates that she is strengthened for navigation in polar ice conditions with the presence of multiyear ice floes. Furthermore, the notation "Ice Breaker" states that she is designed and constructed for breaking ice to open navigable channels for other ships. [1] [45]
Yamal can break ice while making way either forwards or backwards. Yamal is one of the Russian Arktika family of icebreakers, the most powerful icebreakers in the world. These ships must cruise in cold water to cool their reactors [failed verification], so they cannot pass through the tropics to undertake voyages in the Southern hemisphere. [3]
[25] [26] With a total propulsion power of 60 megawatts (80,000 hp), Leningrad is designed to be capable of breaking 2.8 metres (9 ft) thick level ice at a continuous speed of 1.5–2 knots (2.8–3.7 km/h; 1.7–2.3 mph) at full power when operating in deep water at design draught.
