The hybrid propulsion system of the new icebreaker is a further development of the traditional double acting concept and will consist of two 7.5 MW ABB Azipod units and a fixed 10 MW centerline shaft. The construction of the new polar icebreaker began in 2013 and it is expected to enter service in the Northern Sea Route in 2018. [12] [13] [14]
[6] [20] [28] This will allow the PSCs to break ice with a thickness between 6 and 8 feet (1.8 and 2.4 m). [4] Designed according to the International Association of Classification Societies (IACS) Unified Requirements for Polar Class Ships , the PSCs will be strengthened to Polar Class 2 which is intended for vessels operating year-round in ...
As part of these plans that were published in the early 1990s, a number of both conventional and nuclear-powered icebreaker icebreaker type size series were developed, ranging from 7-megawatt auxiliary icebreakers (LK-7) operating near large ports to 110-megawatt nuclear icebreakers (LK-110Ya) capable of breaking ice up to 3.5 metres (11 ft) thick.
Singh noted that the U.S. has only two icebreakers, and both are nearing the end of their usable life. Finland has 12 icebreakers and Canada has nine, while Russia has 36, according to U.S. Coast ...
