The coastline of Russia along the Arctic ocean is so great that the icebreaker fleet the country needs. But the icebreakers are working not only in the North. They hold court all year round, and frozen seas and rivers.

History of the icebreaker fleet of Russia

On the Northern rivers of Russia's icebreaker boats were used for a long time. The first icebreaking ship type was built in Kronshtadt in 1864, and in the late nineteenth century was officially created icebreaker fleet. The famous icebreaker «Ermak», which belonged to Vice-Admiral S. O. Makarov, famous scientist D. I. Mendeleev, was founded on the English shipyard in 1897.Diesel icebreakers

The Naval Ministry of Russian Empire in 1913, announced a competition for the construction of twelve linear and port icebreakers. The world's first linear icebreaker “history” was built in 1917 by the firm “Sir Armstrong and°” by S. O. Makarov. Later it was renamed and began to carry the name “Krasin”.

The First Soviet icebreakers were built in domestic shipyards in 1938—1941. The ice fleet of the Soviet Union consisted of vessels of domestic, British, German, Danish, Finnish and canadian-built.

A Soviet icebreaker fleet the first in the world added nuclear ice breaker "Lenin" in 1959, built at the Admiralty shipyard.

Diesel icebreakers for the Soviet fleet built in the shipyards of Finland. These were powerful ships of “Moscow” and type icebreakers "Kapitan Sorokin” with a capacity of 16.2 MW, are designed for navigation at the mouth of Arctic rivers and in areas with small depths and at temperatures of -50°C as well as breakers of the type “Mudyug”. By the end of Soviet history of Russian icebreaker fleet consisted of 36 vessels.

The Island of Mudyug

In the White sea near the mouth of the Northern Dvina river is an island with scenic beauty, which attracts tourists and the beauty of the sea and clean air, and a terrible story. Mudyug to Arkhangelsk was of great strategic value, is the same as Kronstadt to St. Petersburg.

During the first world war and the beginning of the civil war here was created by the interventionists concentration camp for prisoners of war, who later became exiled convict prison. In the camp, and then prison were inhuman conditions, survived there are few, so Mudyug called “island of death”.

Now the island is historical-natural reserve, which includes remnants of the camps and prisons, French sign of the lighthouse in 1875 and the lighthouse built in 1938.

The monument to the victims of the intervention was installed in memory of those who died on the island in 1928, first in stone and cement, and in 1958 it was replaced with granite. Ship "Mudyug"
with the Name of the island called a ship. “Mudyug” – diesel-electric icebreaker capacity of 7 MW, built in 1982.

Icebreaker «Mudyug”

The Translation of the name from Finno-Ugric – “crooked river". The name, in General, corresponds to the current operation of the auxiliary icebreaker.

It was Built in 1982 on the famous Finnish shipyard “Vyartsilya" (the Finland icebreakers break the ice in all ice-breaking fleets of the world), as well as two other icebreaker – “Dickson” and “Magadan” – after it.Icebreakers of Finland he Began his career as “Mudyug” from work in the Murmansk shipping company, then was transferred to Arkhangelsk. In 1987 the ‘Mudyug” was reworked by the Swiss project. The front half of the icebreaker was completely rebuilt, and now his nose is like a giant size Shoe. The tank ship was very spacious, but has worse agility and a new nose, which was originally developed for thin ice lakes in Switzerland, was not able to break thick Arctic ice. And auxiliary icebreaker was transferred to Saint Petersburg in the North-West branch of Rosmorport.

Now he cuts new ice on the fairway in the Neva Bay and the strip of clean water after him for pilotage remains wide and smooth.

Features of the icebreaker

The owner of the auxiliary icebreaker «Mudyug” is the North-Western basin branch of FSUE «Rosmorport”, he is assigned in the port of St. Petersburg. The court ‘Rosmorport” to ensure safe navigation in the water areas of Russian ports on the Baltic sea and the approaches to them.

An Icebreaker with a power of 7.3 MW speeds speed in open water 16.5 knots. Its length is 111,6 meters, width – 22,2 meters, sludge – 6,8 meters, the height – 38 meters. The total displacement of the icebreaker – 8,154 thousand tonnes, icebreaking capability – 115 centimeters.

Icebreaking capability – is the ability of an icebreaker to move into solid ice at full power, it shows the ice of the vessel and is measured by the maximum ice thickness where the vessel can continuously with a minimum speed to move."Mudyug" translation

According to “Rosmorport" icebreaker "Mudyug” may twenty-five days to stay in Autonomous navigation, and its swimming area in the Baltic sea is not restricted.

The purpose of the icebreaker

Auxiliary icebreaker «Mudyug” designed for independent icebreaking vessels, that is, make a channel of pure water, free fromice. Since the length of the caravan depends on the length of the channel of clean water for an icebreaker, “Mudyug” can conduct convoys of several ships. Also, it can tow non self-propelled vessels and floating structures not only in ice but in water. Specificity "of an ice-cutter”, which reserves a wide smooth channel, allows it to tow vessels on a long tow."Mudyug" icebreaker

Equipment allows to extinguish fires in any buildings, not just on floating objects and to carry assistance to vessels in distress, and in ice conditions, and clean water.

An Experiment on the modernization of the icebreaker

Initially, icebreaking capability was achieved by increasing the mass of the vehicle and power its power plants. But it turned out that the option in which the ice is cut at a certain angle, and not choking is more effective. A special form of hull lines to push on the sides of the ship cut ice under ice array, leaving the icebreaker a clean strip of water, not ice debris, which not every ship can pass."Mudyug" icebreaker

The West German firm "Thyssen-WAAS” referred to the successful experience of the modernization of the icebreaker «Max Waldeck” and “Mudyug” came to trouble. Long nose and deeply hidden under her blunt part of anchor fairleads and gave occasion to the wags to call the icebreaker “train wreck” or “nostrils".

Because trials occurred in the summer, ice in the area of Franz-Joseph were not very thick, and the tests give satisfactory results. But in the winter on the practical transaction of the courts surfaced that were not previously considered flaws. Astern the break-up to move and never could, and on the front of it was jammed with ice. Moreover glaciologists have proved that multi-year ice with hummocks cutting at all, unlike annuals, which were cut in the test “Mudyug”. Icebreaker eventually transferred to the Baltic.

Festivals icebreakers

In early may, 2014 was held the festival of icebreakers. It was held in St. Petersburg, was the first in the world and was dedicated to the sesquicentennial of the Russian icebreaker fleet. Petersburg parade of icebreakers. Only on the first day of the festival was visited by over ten thousand people. The famous Arctic icebreaker «Krasin” with a rich and heroic history; of the port icebreaker «Ivan Kruzenshtern”, named after the great Explorer Admiral I. F. Krusenstern; one of the six icebreakers, named after the famous Soviet captains “Captain Zarubin”; modern icebreakers rescue equipment for extinguishing fires at sea and combating oil spill «Moscow” and “St Petersburg” – in such a great company worthy place was taken by the worker “Mudyug" icebreaker for pilotage in freezing seas.Parade of icebreakers

The second time the festival was held in may of 2015. It was dedicated to the seventieth anniversary of the Victory and heroism of the Arctic convoys during the great Patriotic war. And St. Petersburg again took the parade of icebreakers. In addition to last year's participants, icebreakers “Krasin», «Ivan Kruzenshtern”, “Mudyug» and «Moscow», participated in the festival “Nevskaya Zastava" and "Kapitan Sorokin”.

The Future of the icebreaker fleet of Russia

Now developed the state program of creation of a new icebreaking fleet of Russia, since the majority of existing vessels is to be discarded.

Includes built diesel-electric icebreakers: linear for use in the Arctic, the power shafts which – 25 MW; linear for freezing seas with a capacity of 16–18 MW; auxiliary with a capacity of 7 MW, as in icebreaker «Mudyug”.

Class Icebreaker LK-25D may, replacing the ice-breakers “Krasin” and “Admiral Makarov”, to ensure the summer of a shipping and pilotage in the East, and year-round – in the Western area of the Arctic, on the Yenisei river.

Icebreakers of type LK-18D, which is intended to replace vessels "Kapitan Sorokin", can provide not only transportation in the East Arctic and the far East, but also in new and promising directions in the far Eastern basin.
Icebreakers of type LK-7D will come not only to replace the auxiliary diesel-electric ships of “Mudyug”.

The Icebreaker of new generation need for the development of new lines of transportation in the far East and the Arctic, and to service new ports and terminals.
