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 .
Prior to ocean-going ships, ice breaking technology was developed on inland canals and rivers using laborers with axes and hooks. The first recorded primitive icebreaker ship was a barge used by the Belgian town of Bruges in 1383 to help clear the town moat.
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.
Using a hovercraft for destruction of ice is desirable because this type of vehicle makes possible a combination of transport and ice-breaking, and its all-terrain qualities facilitate year-round operation. The high speed of destruction of ice by hovercraft can effectively make an early opening of individual sections of rivers and reservoirs.
Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. [1] It is a form of ice ablation or ice disruption. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as an ...
CCGS Terry Fox is a Canadian Coast Guard heavy icebreaker.She was originally built by Burrard-Yarrows Corporation in Canada in 1983 as part of an Arctic drilling system developed by BeauDril, the drilling subsidiary of Gulf Canada Resources.
[26] [27] With a total propulsion power of 60 megawatts (80,000 hp), Yakutiya 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. [3]
