Moskva (1959 Icebreaker)
''Moskva'' ( rus, Москва; literally: Moscow) was a Soviet polar icebreaker and the lead ship of a series of five diesel-electric icebreakers named after major Soviet cities. She was built at Wärtsilä Hietalahti shipyard in Helsinki, Finland, in 1959 and when delivered was the largest and most powerful non-nuclear icebreaker ever built. Shortly after the dissolution of the Soviet Union, ''Moskva'' was decommissioned after a long and successful career along the Northern Sea Route and sold for scrap in 1992. In February 1985, ''Moskva'' became the center of international attention when a herd of beluga whales was trapped by ice near the Chukchi Peninsula in the Soviet Far East. The icebreaker broke a channel through the ice pack and managed to lead about 2,000 whales to the open sea. Construction In 1956, the 20th Congress of the Communist Party of the Soviet Union decided to increase the importance and capacity of the Northern Sea Route. This ambitious plan called ...

Icebreaker Moskva (1959) Under Construction 2
An icebreaker is a special-purpose ship or boat designed to move and Ice navigation, navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened Hull (watercraft), hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's wikt:trim#Noun, trim. In cases of very thick ice, an icebreaker can drive its Bow (ship), bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chukchi Peninsula
The Chukchi Peninsula (also Chukotka Peninsula or Chukotski Peninsula; russian: Чуко́тский полуо́стров, ''Chukotskiy poluostrov'', short form russian: Чуко́тка, ''Chukotka''), at about 66° N 172° W, is the easternmost peninsula of Asia. Its eastern end is at Cape Dezhnev near the village of Uelen. The Chukotka Mountains are located in the central/western part of the peninsula, which is bounded by the Chukchi Sea to the north, the Bering Sea to the south, and the Bering Strait to the east, where at its easternmost point it is only about from Seward Peninsula in Alaska; this is the smallest distance between the land masses of Eurasia and North America. The peninsula is part of Chukotka Autonomous Okrug of Russia. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Murmansk
Murmansk (Russian: ''Мурманск'' lit. "Norwegian coast"; Finnish: ''Murmansk'', sometimes ''Muurmanski'', previously ''Muurmanni''; Norwegian: ''Norskekysten;'' Northern Sámi: ''Murmánska;'' Kildin Sámi: ''Мурман ланнҍ'') is a port city and the administrative center of Murmansk Oblast in the far northwest part of Russia. It sits on both slopes and banks of a modest ria or fjord, Kola Bay, an estuarine inlet of the Barents Sea. Its bulk is on the east bank of the inlet. It is in the north of the rounded Kola Peninsula which covers most of the oblast. The city is from the border with Norway and from the Finnish border. The city is named for the Murman Coast, which is in turn derived from an archaic term in Russian for "Norwegian". Benefiting from the North Atlantic Current, Murmansk resembles cities of its size across western Russia, with highway and railway access to the rest of Europe, and the northernmost trolleybus system on Earth. It lies over 2° n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

Slipway
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's hull is coated with grease, which then allows the ship or boat to "slip" off of the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ships. Pulling large ships against the greased ramp would require too much force. Therefor ...

Wilhelm Wahlforss
Emil Wilhelm Wahlforss (25 June 1891 – 20 June 1969) was a Finnish engineer, industrialist and vuorineuvos. Early life Wahlforss was born in Helsinki, the capital of Grand Duchy of Finland. His father Henrik Alfred Wahlforss was an appreciated chemistry teacher in Polytechnical institute; his mother, Emilia Elisabeth née Långhjelm, was 24 years younger and originally from Ostrobothnia. The couple had four children: 1883 and 1885 born daughters Elisabeth and Henriette, and 1891 and 1895 born sons Wilhelm and Eric. While the father was doing significant research, his work, which was written in Swedish, remained without international attention. Another hindrance for his success was his drinking problem. He died in 1899 when Wilhelm was just eight years old. The family fell into poverty and moved often in the following years, however, staying in the same area, Oulunkylä. Studies During his school years in Swedish Normal School Wilhelm Wahlforss had classmates who later beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lenin (1957 Icebreaker)
''Lenin'' (russian: Ленин) was a Soviet nuclear-powered icebreaker, the first nuclear-powered icebreaker in the world. Launched in 1957, it was both the world's first nuclear-powered surface ship and the first nuclear-powered civilian vessel. ''Lenin'' entered operation in 1959 and worked clearing sea routes for cargo ships along Russia's northern coast. From 1960 to 1965 the ship covered over during the Arctic navigation season, of which almost was through ice. Nuclear power proved to be an ideal technology for a vessel working in such a remote area as it removed the need for regular replenishment of fuel. On 10 April 1974 the vessel was awarded the Order of Lenin. It was officially decommissioned in 1989. It was subsequently converted to a museum ship and is now permanently based at Murmansk. Propulsion When launched in 1957, ''Lenin'' was powered by three OK-150 reactors. In its late-1960s configuration, at full capacity the ship used five to six pounds of uranium-23 ...
