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. [1] [2
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.
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.
Petroleum exploitation companies operate a fleet of Ice Breaking Emergency Evacuation Vessels (IBEEV) on the Caspian Sea, to service the extensive oil fields there. [2] [3] [4] The vessels are designed to evacuate up to 338 individuals per trip. They are designed to function using compressed air to power their engines, if they are passing ...
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 ...
[72] [73] With a total propulsion power of 60 megawatts (80,000 hp), Arktika 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.
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 .
