A river icebreaker is an icebreaker specially designed to operate in shallow waters such as rivers and estuaries, and often able to pass through canals and under bridges. [1] As published by the American Society of Civil Engineers in 1916, "On some rivers, particularly where melting first takes place on the upper river, as on the Oder and Weichsel in Germany, the formation of ice jams is a frequent cause of floods." [2] River icebreakers can operate in any navigable waterway to prevent such ice jams. [3]

Various river icebreakers, from smaller vessels to the nuclear-powered shallow draft icebreakers Taymyr-class Vaygach and Taymyr, [4] are also in service in the large rivers of the Russian arctic.

The oldest river icebreaker in the world that is still in service is the Kuna .

The Kara Sea is a marginal sea, separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya, and from the Laptev Sea to the east by the Severnaya Zemlya archipelago. Ultimately the Kara, Barents and Laptev Seas are all extensions of the Arctic Ocean north of Siberia.

An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom.

<span class="mw-page-title-main">Nuclear-powered icebreaker</span> Type of ship

A nuclear-powered icebreaker is an icebreaker with an onboard nuclear power plant that produces power for the vessel's propulsion system. Although more expensive to operate, nuclear-powered icebreakers provide a number of advantages over their diesel-powered counterparts, especially along the Northern Sea Route where heavy power demand associated with icebreaking, limited refueling infrastructure along the Siberian coast, and endurance required make diesel-powered icebreaker operations challenging. As of 2023, Russia is the only country that builds and operates nuclear-powered icebreakers, having built a number of such vessels to aid shipping along the Northern Sea Route and Russian arctic outposts since the Soviet era.
