Arktika (icebreaker)
Nuclear-powered icebreaker Arktika
The nuclear-powered icebreaker Arktika (Russian Арктика ) is a Russian nuclear-powered icebreaker Arktika the class, which was designed to work in polar regions. It is the successor model of Lenin.
History
On December 26, 1972, the Arktika ran in Leningrad at the Baltic shipyard stack. Upon completion, the ship was thoroughly tested until it was handed over on 25 April 1975, the Russian shipping company Murmanskoje Parochodstwo in Murmansk. The Arktika made at that time the flagship of the Soviet nuclear icebreaker fleet dar. For more than a decade was the Arktika the most powerful nuclear- powered non-military ship in the world. The icebreaker was designed specifically for the ice-free - hold in the northern sea routes. Task was to extend the shipping period and to allow faster passage. The Arktika was several years out of service until it was fully restored back in the late 1990s. In 2007, the icebreaker was ready for use again.
On 9 April 2007 broke on the Arktika from a fire that took three cabins and the ship's electrical system affected. The two nuclear reactors were not damaged and there were no injuries. Following the ship to Murmansk was ordered for repair work.
On 3 October 2008, the shutdown of the reactors and thus the immobilisation of the vessel after the estimated period of use was covered by eight years.
Technology
The Polar icebreaker has, based on the design draft of 11.0 meters, a length in the design waterline of 136.0 meters. The overall length is 148.0 meters. The width is 30 meters. The displacement of the double hull is unloaded 19,300 tons and 23,460 tons at maximum load. The ship has two OK - 900A nuclear reactors, each of which generates an output of 171 MW. The heat generated in the reactor makes in two turbine sets a total of 75,000 WPS ( 55,200 kW). Arktika the three drive screws which are electrically turbo rotated. The maximum free - running speed amounts to 21 kn. For that time the ship with the most modern navigation and radio equipment was fitted. The establishment of the occupation is relatively comfortably designed to make long stays at sea as pleasant as possible.
North Pole journey in 1977
The Arktika reached on August 17, 1977 as the first surface vessel to the geographic North Pole at 4:00 Moscow time clock. At the pole of the Arctic Ocean is more than 4,000 meters deep. With the help of a crane, a metal plate was lowered into the North Sea, the inscription " USSR. 60 years of October. Nuclear-powered icebreaker Arktika " to commemorate the October Revolution. After addition the flag of the USSR was hoisted, the ship finally took 19:05 clock again heading for home port of Murmansk. When the icebreaker on August 23, again in 1977 arrived at the home port, 3852 miles were covered in 13 days, of which 1609 nautical miles. Strong through ice fields
