This is a list of icebreakers and other special icebreaking vessels (except cargo ships and tankers) capable of operating independently in ice-covered waters. Ships known to be in service are presented in bold .
An icebreaker is a brief facilitation exercise intended to help members of a group begin the process of working together or forming a team.They are commonly presented as games to "warm up" a group by helping members get to know each other and often focus on sharing personal information such as names or hobbies.
Prior to ocean-going ships, ice breaking technology was developed on inland canals and rivers using laborers with axes and hooks. The first recorded primitive icebreaker ship was a barge used by the Belgian town of Bruges in 1383 to help clear the town moat.
Although icebreaking cargo ships had been built in the past, their hull forms were always compromises between open water performance and icebreaking capability. A good icebreaking bow, designed to break the ice by bending it under the ship's weight, has very poor open water characteristics and is subjected to slamming in heavy weather. However ...
The amplitude of the FGW increases sharply and, with a sufficient load, destruction begins. The power consumption is several times lower (depending on the thickness of the ice) compared with icebreakers and ice-breaking attachments. This method of ice destruction is known as the resonance method.
Magadan ' s hull is 88.5 metres (290.4 ft) long overall and has a beam of 21.2 metres (69.6 ft) at its widest point. [5] However, the towing notch increases the extreme length of the vessel to 92.0 metres (301.8 ft) while the inclined sides reduce the hull width to 20.0 metres (65.6 ft) at the design waterline. [6]

Yermak assisting the stranded warship Apraxin, 1900 1976 Soviet postage stamp honoring the Yermak. An earlier vessel, the schooner Yermak, was commissioned for the 1862 attempt to find the Yenissei river delta by Paul Theodor von Krusenstern, by navigating from Murmansk through the Kara Sea to the destination, but unfortunately was shipwrecked before obtaining success.
