Icebreakers of Russia
The first Soviet nuclear-powered icebreaker, Lenin

There is a disagreement as to whether the Russia first "true" icebreaker was Pilot (manufactured in Great Britain in 1862, whose ice-breaking capabilities were enhanced in Russia in 1864) or genuinely first 1898 Arctic ice-faring icebreaker Yermak.[1]

Classification

[edit]

In Russia, icebreakers are classified in several ways, according to different criteria:[2][3]

  • By purpose
    • Leader icebreakers: The most powerful icebreakers that head ship caravans
    • Line icebreakers: For guiding and towing of ships on sea routes, for freeing ice-stuck ships
    • Auxiliary icebreakers: for work in ports, river mouths, and for emergency rescue operations
  • By ice passability:
    • heavy icebreakers can break through ice up to 2 m thick
    • medium icebreakers, for ice from 1 to 1.5 m thick
    • light icebreakers, for ice less than 1 m thick
  • By power type:
  • By operating method
    • Ice-cutting. These ships existed in 19th-20th centuries, and for them the term "icecutter" [ru] was used in Russia[4]
    • Ice-breaking
  • By operational area
    • River icebreakers
    • Marine icebreakers
    • Port icebreakers

The official classification of a particular vessel may be found in the database of the Russian Maritime Register of Shipping.[3]
