  Icebreaker - Wikipedia, the free encyclopedia
Essential to an icebreaking vessel is the ability to propel itself onto the ice, breaking it, and then successfully clearing the ice debris from its path.
Icebreakers are expensive to build and very expensive to run, whether the icebreaker is powered by gas turbines, diesel-electric powerplant or nuclear energy.
A modern icebreaker typically has shielded propellers both at the bow and at the stern, as well as side thrusters; pumps to move water ballast from side to side; and holes on the hull below the waterline to eject water bubbles, all designed to allow an icebreaker stuck amidst thick ice to break free.

Several technological advances were introduced over the years, but it was not until the introduction of nuclear power (icebreaker Lenin, 1959) that icebreakers developed their full potentials.
Icebreakers are expensive to build and very expensive to run, whether the icebreaker is powered by gas turbines, or is a nuclear powered icebreaker.
Icebreakers have a round sled-like bow, however; they tend to slam into waves, which can be a risk in high seas.

 CCGS Terry Fox - Wikipedia, the free encyclopedia
MV Terry Fox, along with her sister ship MV Arctic Kalvik supported Gulf Oil's operations in the Beaufort Sea during the 1980s.
MV Terry Fox was acquired by the Canadian Coast Guard in 1992 and renamed CCGS Terry Fox.
Classed as a "Heavy Gulf Icebreaker" by the coast guard, she is stationed at CCG Base Dartmouth in Dartmouth, Nova Scotia and operates in the Gulf of St. Lawrence during the winter ice season and in Canada's eastern Arctic during the summer shipping season, assisting in escorting the annual Arctic summer sea-lift to coastal communities.

They are uncomfortable to travel in on the open sea: Almost all of them have rounded keels and with no protuberances for stability they can roll even in light seas.
The shape which allows icebreakers to move through ice also make the ship uncomfortable in open water and have poor fuel effiency.
Icebreakers with the round; sled-like bow used to ride up on the ice; tend to slam into waves and can be a risk in high seas.

 Games > Video Games > Puzzle > Icebreaker
At a beginning of the 20th Century several countries began to operate purpose-purpose-made icebreakers; virtually all were coastal icebreakers, however Russia and later a Soviet Union also built several seagoing icebreakers of in the area of 10,000 metric ton displacement.
Icebreakers come required to keep trade routes open in which there are either seasonal or even lasting ice conditions.
Icebreakers come expensive to build & super expensive to redo, whether a icebreaker is powered by gas turbines, diesel-electric powerplant or nuclear energy.

We left Resolute Bay this morning at exactly 0800, heading east to our rendez-vous with the MV 'Arctic', the bulk carrier which we are to escort into the 'Polaris' mine on 'LCI'-- Little Cornwallis Island.
Icebreaking technique is fairly simple in principle, but you still have to know a lot to run any ship, and more to run one of these.
Some icebreakers use 'trim tanks' to change the way the ship floats in the water to help free her if she gets pinched, by rocking her from side to side or fore and aft.

 NORTHERN ICE 2001
Last night, the MV Arctic was stopped dead in her track a number of times, necessitating our backtracking to rescue her from icebound imprisonment.
The ice surrounding the MV Arctic was under such tremendous force that mounting ridges, built of chunks of ice, transected the surface of the floes.
After reaching LCI with the MV Arctic, the plan is to wait with her as she is loaded, a process that takes several days, then escort her back out of the ice west into open water.

The Arctic Sunrise was blockading a 130-metre sea barge to prevent it docking at BP's controversial Arctic oil project, Northstar.
Greenpeace's 50 metre icebreaker had positioned itself adjacent to the offshore drilling island to stop the barge from off-loading BP's new control centre and accommodation module when BP served an injunction on the ship and its crew.
The Arctic is on the front-line of global warming by the burning of fossil fuels.

Further skills were honed on board MV Arctic – then the world's highest ice-class cargo ship – which operated in the ice before and after the seasonal presence of icebreakers.
With an ice-strengthened vessel, avoidance is the key, whereas icebreaking vessels can meet the ice head on, and work it.
Stints with Canarctic Shipping Company Ltd. on board MV Arctic were followed by a return to the coast guard in the late 1990s.

The nuclear icebreaker Yamal was built in St. Petersburg, Russia in 1992 by Murmansk Shipping Company and is one of five ice-breakers in this class.
With a displacement of 23,000 tons, 75,000 total horsepower and an armour steel icebreaker hull no less than 48mm thick, the Yamal is among the world's most powerful and sophisticated ships.
With the world's largest and most modern fleet of icebreakers, the Russians are recognised experts in polar operations.

 NCE Knowledge Site -- Sea Ice in the Canadian Arctic in the 21st Century   (Site not responding. Last check: 2007-11-02)
With the waterways among the Arctic islands more open in summer, there could be more incursions of multi-year ice from the Arctic Ocean into the main navigation channels of the archipelago (at least until further in the future when the Arctic Ocean itself might become ice-free in summer).
The MV Arctic takes cargo from the Raglan mine on Hudson Strait throughout the winter -- a commitment that would have been unthinkable a decade ago.
In addition, if the Canadian Arctic were to have significantly easier ice conditions in the future, we would likely see the introduction of a new type of marine traffic -- vessels transiting the area without making a Canadian port of call.

The Arctic Sunrise is a vessel that has spent most of its life in ice regions, has now been converted to be a fully fledged campaigning vessel.
It has al ready been a very active ship in the fleet, having started its Greenpeace life doing an oilrig tour in the North Sea exposing some of the major pollution that is happening from these platforms.

Emily Craddock, 27, a radio operator, was last seen on board the MV Arctic Sunrise shortly after midnight on Friday as the vessel was returning from a campaigning tour 1,500 miles north of Rio de Janeiro.
The region between Porta de Moz, where the Arctic Sunrise was returning from, and Belem is of the main areas of rainforest destruction in the Amazon, where more than 10,000 square miles of forest is estimated to vanish every year.
Ms Dunlop said: "The Arctic Sunrise is zig-zagging throughout the area and co-ordinating grid searches of the river but we are only able to search during daylight." Greenpeace is also asking the communities who live on the banks of the Amazon to help in the search.

Newly appointed as chief inspector at the Brazilian Federal Environment Agency (Ibama), he is leading a clampdown on illegal logging in the Fazenda Esperanca, whose 2 million hectares of verdant flood plain forest have since 2002 been ravaged by a rapid increase in deforestation.
The Arctic Sunrise had dropped her anchor somewhat provocatively opposite the frontier logging town of Porto de Moz.
The Arctic Sunrise’s draught restricts her from entering the Amazon’s shallower tributaries, so in order to get to the remoter communities on whose support the proposed extractive reserves rely Greenpeace chartered a river boat, the Captain Dario.

Ironically, this ship was built in 1975 for commercial seal hunting and then acquired by the French government as a supply vessel, for their Antarctic oil and mineral exploitation.
In 1997 it became the first ship to circumnavigate James Ross Island in the Antarctic, which previously was an impossible journey until a 200m thick ice shelf connecting the island to the Antarctic continent collapsed.
Sadly, not much had changed – the loggers were still at it and the Arctic Sunrise found shiploads of illegal logs bound for export.

 4aAB5 A model for assessing the impact of vessel noise on odontocete   (Site not responding. Last check: 2007-11-02)
A probabilistic model of sound detection was developed for assessing the impact of underwater icebreaker noise on signal detection by beluga whales and narwhals.
The probability of detecting sample signals, in the absence of vessel noise, was compared to that of detecting the same signals in ship noise, using the MV arctic, as a sample noise source.
Analysis of signal detection probabilities showed that loud signals centered on the 5-kHz critical band were more severely masked by ship noise than were quiet 5-kHz signals or loud 2-kHz signals.
