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.
Diversity Icebreaker is used to work on a wide range of subjects from focus on communication and interaction in general to more specific topics like team development, intercultural relations, learning styles and conflict resolution.
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 .
When a ship becomes immobilized by ice, the icebreaker has to free it by breaking the ice surrounding the ship and, if necessary, open a safe passage through the ice field. In difficult ice conditions, the icebreaker can also tow the weakest ships. [11] Finnish icebreaker Otso escorting a merchant ship in the Baltic Sea
Nuclear icebreaker Yamal, 2015. 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 diesel-powered icebreaker operations are ...
Polar-class icebreakers USCGC Polar Star (WAGB-10), USCGC Polar Sea (WAGB-11) are heavy icebreakers operated by the United States Coast Guard (USCG). These cutters, specifically designed for icebreaking, have reinforced hulls, special icebreaking bows, and a system that allows rapid shifting of ballast to increase the effectiveness of their icebreaking.
Because of the limitations of traditional propulsion systems, the double acting ship concept wasn't seriously considered until the development of electric podded propulsion units which combine the advantages of the diesel–electric powertrain, already widely used in icebreakers, with the excellent manoeuvrability of azimuth thrusters.

The U.S. Coast Guard Cutter Thunder Bay (WTGB-108) clears a channel for vessels to navigate the frozen Hudson River. 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]
