USCGC Healy at right breaks ice around the Russian-flagged tanker Renda, 250 miles (400 km) south of Nome, Alaska.. An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships.
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 ...
The Ice Breaker Tournament (also called the Ice Breaker Invitational or the Ice Breaker Cup) is a college Division I men's ice hockey tournament played annually at the start of each season. [ 1 ] The tournament began play in 1997 as an exhibition [ 2 ] and was created as an early-season showcase for top-ranked teams from four separate conferences.
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.
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.
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 ...
Yamal can break ice while making way either forwards or backwards. Yamal is one of the Russian Arktika family of icebreakers, the most powerful icebreakers in the world. These ships must cruise in cold water to cool their reactors [ failed verification ] , so they cannot pass through the tropics to undertake voyages in the Southern hemisphere .
[26] [27] With a total propulsion power of 60 megawatts (80,000 hp), Chukotka is designed to be capable of breaking 2.8 metres (9 ft) thick level ice at a continuous speed of 1.5–2 knots (2.8–3.7 km/h; 1.7–2.3 mph) at full power when operating in deep water at design draught.
