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.
The Cambridge examination board offers an ICE (International Certificate in Education) group qualification for candidates who achieve 7 subject passes across the following groups: [4] Group 1: Languages; Group 2: Humanities and Social Sciences; Group 3: Sciences; Group 4: Mathematics; Group 5: Creative and Vocational (Professional and Creative)
In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull to direct the broken ice around or under the vessel.
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.
Oden is a large Swedish icebreaker, built in 1988 for the Swedish Maritime Administration.It is named after the Norse god Odin.First built to clear a passage through the ice of the Gulf of Bothnia for cargo ships, it was later modified to serve as a research vessel.
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 ...
