Russian nuclear icebreakers
• Nuclear icebreakers Russia
has the most extensive Russian icebreaker fleet among the countries, and a unique design experience, construction and operation of such vessels. Icebreakers provide stable operation of the Northern Sea Route, as well as access to the Far North and the Arctic shelf. Nuclear icebreakers are much more powerful diesel, the most important advantage of such a fleet - no need regular refueling, which is convenient and profitable in the permafrost.
Nuclear icebreaker fleet evolved almost in parallel with the national nuclear energy. The decision to build the first nuclear-powered icebreaker was taken November 20, 1953, and after 6 years of icebreaker "Lenin" was launched.
Now the nuclear icebreaker fleet has 6 nuclear-powered icebreakers, 1 and 4 container vessel technological service. Ships based in Murmansk in the center of FSUE "Atomflot".
The first step is to meet the base Atomflot icebreakers "Vaigach", commissioned in 1990, and the "Soviet Union", which is on the refurbishing.
The icebreaker "Soviet Union" was put into operation in 1989. In March 2002, during the icebreaker parking at the dock in Murmansk, the first of its power plant it has been used to supply electricity onshore facilities. In this case the unit capacity reached 50 megawatts. It is interesting that the icebreaker "Soviet Union" is designed so that in a short time, it can be converted into a warship.
Icebreaker "Vaigach" was built in Finland in the Wärtsilä shipyard in 1990 and characterized by a reduced draft, intended for piloting in the mouth of the Siberian rivers. Nuclear energy installation has an output of 50,000 horsepower and lets the icebreaker to go through the ice two meters thick.
The icebreaker "Russia" looks out of the tap. It was founded February 20, 1981 and served until 2013. Is the fourth in the world icebreaker with nuclear power plant. Technically, "Russia" can independently go through the tropics to work in the Antarctic, but there is a risk of high wear most of the vessel's machinery. Currently, the icebreaker is in the sludge, and started the process of unloading the spent fuel.
Nuclear workers laugh meaning ships' names - "Russian" destroyed, and "Soviet Union" is reduced.
Go ahead on the base. In the vast floating repair dock was nuclear-powered icebreaker "Yamal" and passed scheduled maintenance.
"Yamal" was founded in 1986 and launched in 6 years. In 2000, he made an expedition to the North Pole to meet the third millennium. In the repair dock to the ship we will be back later!
Icebreaker "Siberia" is currently in cold sludge and fully prepared for recycling in 2015. Ships has worked at sea from 1977 to 1992. Vyvden of operation due to a fault of steam generators
Power nuclear power plants - 75 000 hp and a top speed of 20 knots, a displacement of 21,120 tons.
On the nose icebreaker had gun mount, and the bow presumably had a P-shaft 13 for ballistic missiles. The living quarters are mounted on elastic bearings and dampers, to not hear the noise.
The icebreaker "Arktika" is the ancestor of its class and the first who visited the North Pole. It was August 17, 1977. Currently, the icebreaker is in the port of Murmansk on the "cold sludge". In August 2008, he was taken out of service.
In the distance the ships go.
Over 33 years of trouble-free operation the icebreaker in the Arctic ice was more than a million miles. In 1999-2000 he worked in the Arctic Ocean without refueling, and year of entry into port.
Lifeboats on the icebreaker "Sibir".
The vessel placed nearly 1300 rooms: 155 cabins, galley and dining room, club-cinema hall for 108 seats, a medical unit to the operating room, a gym, a library, two power backup and emergency diesel generators, workshops, fire fighting and ventilation systems , helipad, broadcasting center and other household facilities to ensure a comfortable life of the crew during prolonged isolation "from the mainland."
Go back to the icebreaker "Yamal".
Repair floating dock is, in fact, is the same ship. Doc plunged almost entirely in the water, it comes to the ship, requiring repair. By boat placed props, on which it will stand for all time of work, and the Dock pops up with the vessel top.
The extent of the ice-breaker and repair dock, of course, staggering. It is a pity that the picture can not convey the actual size of designs!
This is one of all nuclear-powered ships, which currently runs on the Northern Sea Route. Total "Yamal" has made 46 flights to the North Pole.
The vessel can chop ice, moving both forward and backward. motor reversing, change of the direction of rotation from full speed to one side to complete the other takes 11 seconds with a weight of 50 tons of screws!
nuclear icebreaker "Yamal" has a double hull, made of steel AK-28. In place of collision with ice outer casing has "ice belt" five-meter height of 46 mm, and in other places of the outer body thickness of about 30 mm. Polumillimetrovym housing is coated with a layer of special ink "Inerta-160" to reduce friction.
Power plant capacity - 75 thousand horsepower, displacement - 23 000 tons.
In addition to the support of the courts, walking along the Northern Sea Route, rescue, service stations and maintenance of the drifting expedition "Yamal" commits tourist cruises to the North Pole.
The base of the nuclear fleet is located quite close to the center of Murmansk. Sea Port stretched along the coast, so the absolute silence, as it may seem, is not around. Softly came the roar of engines, honking ships, the sound of construction, the sound of waves!
Sebyashechka, so to speak, for the scale.
On the icebreaker "Yamal" happened a few accidents. For example, in 2009 in the Yenisei Gulf of the Kara Sea, during the ice channeling, there was a collision, "Yamal" tanker "Indigo." As a result of impact on the main deck of the tanker a crack total length of 9 meters 5 with the opening 8 mm. The tanker was following in ballast, environmental pollution has not occurred. As a result, the tanker was escorted "Yamal" to repair Arkhangelsk.
The result was a general review of the nuclear fleet. In the next post I will tell in detail about the icebreaker "50 Years of Victory". Show the inside of the device, components, various compartments and levels of nuclear vessel.
