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.
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.
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]
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 ...
The icebreaker will also be fitted with an air bubbling system that provides hull lubrication and reduces ice friction during icebreaking operations. [ 4 ] For maneuvering at ports as well as stationkeeping capability in Sea State 5 and currents of up to 3 knots (5.6 km/h; 3.5 mph) in open water, Arpatuuq will also be fitted with two 1,900 kW ...
The Kapitan Khlebnikov was completed in Finland in 1981 [3] as one of four Kapitan Sorokin-class icebreakers.She was refitted in 1990 as a tour ship [4] and was the first ship to circumnavigate Antarctica with passengers in 1996–97.
If static force is applied to a sheet of ice it will flex slightly before suffering a catastrophic failure. Since the ice will bend slightly when any capable vehicle travels on ice-covered water, it follows that travelling at some critical speed may impose sufficient flexing of the ice sheet to cause resonance, and this may result in positive feedback effectively amplifying the oscillation ...
