The need for construction of specialized ships to clear the path in the ice appeared in the mid-18th century. The first icebreaker was a wheeled steamer that cleared ice in the harbor of Philadelphia. Requirements for icebreakers have been tightened, so wheels were replaced by vents and turbines, and internal combustion engines were replaced by nuclear power units. The highest demand for icebreakers is expected to be in Russia, since part of the seas and estuaries there are covered with a thick layer of ice most of the year. In this release, we will check out 5 largest nuclear icebreakers in the world.
