Russian fishing 3.9

A nuclear-powered icebreaker is a russian fishing 3.9 purpose-built russian fishing 3.9 use in waters covered with ice. The only country constructing nuclear-poweredicebreakers is Russia. Nuclear-poweredicebreakers have been constructed by the USSR and later Russia primarily to aid shipping along the Northern Sea Route in the frozen Arctic waterways north of Siberia. Nuclear-powered icebreakers are much more powerful than their diesel-powered counterparts, and although nuclear propulsion is expensive to install and maintain, very heavy fuel demands and limitations on range, compounded with the difficulty of refueling in arctic region, can make diesel vessels less practical and economical overall for these ice-breaking duties.

During the winter, the ice along the Northern Sea Route varies in thickness from 1.2 to 2.0 metres (3.9 to 6.5 feet).

The ice in central parts of the Arctic Ocean is on average 2.5 metres (8.2 ft) thick. Nuclear-powered icebreakers can force through this ice at russian fishing 3.9 up to 10 knots (19 km/h, 12 mph). In ice-free waters the maximum speed of the nuclear-powered icebreakers is as much as 21 knots (39 km/h, 24 mph).

In August 2012 Russia's state-owned nuclear corporation, Rosatom, signed a contract russian fishing 3.9 begin construction on what will be the world's largest nuclear icebreaker, a "universal" vessel that could navigate both shallower rivers and the russian fishing 3.9 depths of the Arctic.[1]

Uses of nuclear-powered icebreakers[edit]

Russian Arktika-class icebreakers are used to force through the ice for the benefit of cargo ships and other vessels along the Russian fishing 3.9 Sea Route, which comprises the eastern part of the Barents Sea, the Pechora Sea, the Kara Sea, the Laptev Sea, and the Eastern Siberian Sea to the Bering Strait.

Other important ports include Dikson, Tiksi, and Pevek. Of six Arktika-class icebreakers built in 1975–2007, four are russian fishing 3.9 in service.

Two shallow-draft nuclear-powered icebreakers, Vaygach and Taymyr, have been built for shallow waters and are usually used from the Yenisei River to Dikson, where they break through the ice followed by cargo ships with lumber from Igarka and cargo ships with ore and metals from the Norilsk Company's port in Dudinka.

The icebreakers have also been used for a number of scientific expeditions in the Arctic.

On August 17, 1977, Arktika was the first surface vessel in the world to reach the North Pole. Since 1989, some icebreakers have been used for Arctic tourist cruises.

Russian nuclear icebreakers[edit]

In all, ten civilian nuclear-powered vessels have been built in the USSR and Russia.

Nine of these are icebreakers, russian fishing 3.9 one is a container ship with an icebreaking bow. All six nuclear-powered icebreakers of the Arktika class have been built at the Baltic Shipyard in St. Petersburg. Vaigach and Taimyr were built at the Helsinki New Shipyard in Finland and then brought to Russia for installation of the reactors and turbogenerators.

Ships[edit]

Lenin[edit]

At its launch in 1957 the icebreaker NS Lenin was both the world's first nuclear-powered surface ship and the first nuclear-powered civilian vessel.

Lenin was put into ordinary operation in 1959. Lenin russian fishing 3.9 two nuclear accidents, the first in 1965, and the second in 1967.

The second accident resulted in one of the three OK-150 reactors russian fishing 3.9 damaged russian fishing 3.9 repair.

All three reactors were removed, and replaced by two OK-900 reactors; the ship returned to service in 1970. The Lenin was taken out of operation in November 1989 and laid up russian fishing 3.9 Atomflot, the base for nuclear-powered icebreakers, in the Murmansk Fjord. Conversion to a museum ship was scheduled to be completed during 2005[update].

Arktika russian fishing 3.9 article: Arktika class icebreaker

Arktika class icebreakers are the bulk of the Russian nuclear icebreaker fleet; six of Russia's ten nuclear civilian ships are Arktikas.

Since they have been built over a period of thirty years, ships of russian fishing 3.9 classes vary among one another; thus specifications are listed as a range of values. In general, the newer ships are larger, faster, and require smaller crews.

Specifications:

  • Length: 148 m to 159 m (approximately 136 m at the waterline)
  • Beam: 30 m (28 m at russian fishing 3.9 waterline)
  • Draft: approximately 11.08 m.
  • Height (keel to masthead): approximately 55 m
  • Displacement: 23,000 to 25,000 tons
  • Maximum speed: 18 to 22 knots
  • Cruising speed: approximately 18 to 20 knots
  • Crew: 138 to over 200
  • Passengers: approximately 100
  • Reactors: 2 OK-900A, 171 megawatt each
  • Propulsion: 3 propellers totalling approximately 75,000 hp
  • Maximum ice thickness: 2 to 2.8 m
  • Endurance: 7.5 months at sea, 4 years between refuelings

Arktika-class icebreakers have a double hull, with the outer hull being approximately 48 mm thick at the ice-breaking areas and 25 mm thick elsewhere.

There is water ballast between the inner and russian fishing 3.9 hulls which can be shifted to aid icebreaking. Icebreaking is also assisted by an air bubbling system which can deliver 24 m³/s of air from jets 9 m below the surface. Some ships have polymer coated hulls to reduce friction. Arktika-class ships can break ice while making way either forwards or backwards. Although they have two reactors, normally only one is used to provide power, with the other being maintained in a standby mode.

Some ships carry one or two russian fishing 3.9 and several Zodiac boats.

Radio and satellite systems can include navigation, telephone, fax, and email capabilities.

Most nuclear-powered icebreakers in the Russian service today have a swimming pool, a sauna, a cinema, and a gymnasium.[citation needed] In the restaurants aboard there is a bar and facilities for live music performances. Some also have a library and at least one has a volleyball court.[citation needed]

Individual ships[edit]

On 17 August 1977, NS Arktika ("Arctic") became the first surface russian fishing 3.9 ever to reach the North Pole.

Arktika was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.[2] Rather than be scrapped, there are calls for her to be converted to a museum ship, like her predecessor Lenin.[3]

NS Sibir ("Siberia") ceased operation in 1992 and is awaiting scrapping.[4]

The NS Rossiya ("Russia") carries two helicopters.

Rossiya was used to transport an expedition of around 40 West Germans to the North Pole in the Summer of 1990; this may have been the first non-communist charter of a nuclear icebreaker. Rossiya was in refit as of December 2004.

The NS Sovetskiy Soyuz ("Soviet Union") was trapped in ice for three days in 1998.

In 2004 it was one of three icebreakers used for an Arctic ice core expedition intended to research climate change and global warming.

The NS Yamal is mostly used for tourism and scientific expeditions.

It has 50 passenger cabins and suites, and carries one helicopter. The crew is 150, including 50 officers and engineers. Yamal was the 12th surface ship ever to reach the North Pole.

The NS 50 Lyet Pobyedi ("50 Years of Victory") is the final Arktika class ship. It was launched from the shipyard at Saint Petersburg on December 29, 1993, as the NS Ural, and delivered to Murmansk in 1994. It was later renamed and not actually completed and commissioned until 2006 due to funding delays.

The crew is expected to normally number 138 russian fishing 3.9. It has an environmental russian fishing 3.9 processing module added to the hull which accounts for 9 m of the ship's 159 m length; this makes it the largest of the Arktika class and the largest nuclear-powered icebreaker in the world. It carries two Ka-32 helicopters. It entered service on April 2, 2007.

Taymyr class[edit]

Taymyr and russian fishing 3.9 sister ship, Vaygach, were built at the Helsinki New Shipyard in Finland by Wärtsilä.

The nuclear reactors were installed at the Leningrad Baltic Shipyard in the Soviet Union after delivery from Finland.[5]

Specifications:

  • Length: 150.2 m (Taymyr), 151.8 m (Vaygach)
  • Beam: 29.2 m
  • Draft: 8.0 m
  • Height: 15.2 m keel to main deck, 8 stories from main deck to bridge
  • Displacement: 20,000 tons
  • Speed: 18.5 knots
  • Crew: 120 to 138
  • Reactors: One KLT-40M russian fishing 3.9 producing 135 MW
  • Propulsion: 3 propellers totalling 52,000 hp

The bow hull plating is approximately 32 mm thick.

Future icebreakers[edit]

This section needs to be updated.

Please update this article to reflect recent events or newly available information.(June 2015)

Russia russian fishing 3.9 planning to start building new icebreakers, Project 22220 after 2010. In June 2008 the head of the state nuclear russian fishing 3.9 Rosatom, Sergei Kiriyenko, said "It is important to not only use the existing fleet of icebreakers, but also to build new ships, and the first nuclear icebreaker of a new generation will be built by 2015.

This should be an icebreaker capable of moving in rivers and seas", he said. He went on saying that the Iceberg Design Bureau in St. Petersburg would prepare the design of the icebreaker by 2009.[6] According to the BBC the LK-60 (ЛК60Я) will be the biggest nuclear-powered icebreaker that was ever built.[7]Vladimir Putin said in 2010, Russia builds at least three nuclear icebreakers of the new generation in the period from 2012 to 2020.

Sergei Kiriyenko, head of the state nuclear corporation Rosatom ordered the russian fishing 3.9 operator Atomflot to build up to three nuclear icebreakers until 2016.

The russian fishing 3.9 of a nuclear-powered icebreaker takes eight years, the fuel endurance is about 25 years[citation needed] and the reactor can be refueled. According russian fishing 3.9 the Transport Ministry, Russia needs six new icebreakers in the future.[8]

Infrastructure[edit]

Support facilities include the fuel transports Imandra and Lotta which are used for refuelling and spent fuel.

The Volodarsky is used for storage of solid waste; it can hold 300 cubic meters. Serebryanka is a tanker used for liquid waste which can hold 1,000 cubic meters of material.

The Rosta-1 boat is used for radiation monitoring and control, including sanitization of workers.

A third fuel vessel, Lepse, is filled with spent nuclear fuel elements, many of them damaged and thus difficult to handle.

The vessel was used for dumping of nuclear waste in the Barents and Kara Seas from 1963 to 1984.[9] During a dumping operation in 1984, Lepse encountered very rough seas, and high-level reactor waste mixed russian fishing 3.9 water was splashed all over the inside of the russian fishing 3.9 compartment. The contamination was so severe that the crew were forced to immediately return to port at the Atomflot harbor with most of the nuclear waste still in the hold.

The ship was immediately recognized as being far too dangerous to decontaminate and return to service, and has been essentially abandoned with a cargo russian fishing 3.9 full of leaking spent reactor fuel vessels, staying in the harbor for over 15 years. A small crew monitored the ship on a constant basis while Russia tried to raise the money and perform the research needed for safe disposal.

In September 2012 the Lepse was removed from the Atomflot harbor and transported to the Nerpa shipyard where it will be carefully scrapped.[10]

In all, about 2,000 people work aboard the icebreakers, the nuclear-powered container ship, and aboard the service and storage ships stationed at the Atomflot harbour.

The crew on the civil nuclear-powered vessels receive special training at the Makarov college in St. Petersburg, Russia.

Icebreakers generally try to navigate paths with the russian fishing 3.9 possible ice in order to make speedier progress and to help ensure that they do not become trapped in ice too thick for them to break.

russian fishing 3.9

In the russian fishing 3.9 and 1980s, land-based aircraft would observe and map the ice to help with course plotting. Over time, most of russian fishing 3.9 work has been taken over by satellite surveillance systems, sometimes aided by the helicopters carried by the icebreakers.

Arctic tourism[edit]

Since 1989 the russian fishing 3.9 icebreakers have also been used for tourist purposes carrying passengers to the North Pole.

Each participant pays up to US$ 25,000 for a cruise lasting three weeks. The NS Sibir was used for the first two tourist cruises in 1989 and 1990.

In 1991 and 1992, the tourist trips to the North Pole were undertaken by NS Sovyetski Soyuz. During the summer of 1993 the NS Yamal was russian fishing 3.9 for three tourist expeditions in the Arctic.

The NS Yamal has a separate accommodation section for tourists. The nuclear-powered icebreaker russian fishing 3.9 Let Pobedy (known in English as the 50 Years of Victory) contains an accommodation deck customised for tourists.

Quark Expeditions chartered the 50 Years of Victory russian fishing 3.9 expeditions to the North Pole in 2008.

The vessel's maiden voyage to the North Pole embarked in Murmansk, on June 24, 2008. The ship carried 128 guests in 64 cabins in five categories.

50 Years of Victory completed a total of three expeditions to the North Pole in 2008 for the polar adventure company. As of February 2013, Quark Expeditions was listing the 50 Years of Victory in the company fleet[11] and offering it for a North Pole cruise.[12]
