Eisbär (1941 Icebreaker)
''Eisbär'' was a steam-powered Kriegsmarine port icebreaker built at Eriksbergs Mekaniska Verkstad in Gothenburg, Sweden, in 1942. She had two triple-expansion steam engines driving one propeller in the stern and another in the bow of the vessel. In 1946, ''Eisbär'' was handed over to the Soviet Union as war reparations and renamed ''Ilya Muromets'' after the Russian folk hero. She was first used by the Soviet Navy until 1957 and afterwards as a port icebreaker in Vladivostok Vladivostok ( ; , ) is the largest city and the administrative center of Primorsky Krai and the capital of the Far Eastern Federal District of Russia. It is located around the Zolotoy Rog, Golden Horn Bay on the Sea of Japan, covering an area o ... by the Far Eastern Shipping Company until 1979. ''Ilya Muromets'' was broken up in 1981. In the 1950s, the hull form of ''Ilya Muromets'' was used as the basis for the development of the diesel-electric ''Dobrynya Nikitich''-class icebreakers.

Frierfjord
Frier or Frierfjord is a fjord in Telemark county, Norway. The long fjord is located along the Skaggerak coast in the traditional district of Grenland and it forms the border with the municipalities of Bamble, Skien, and Porsgrunn. The fjord is actually an inner arm of the Langesundsfjord, and historically (well into the 1700s) this fjord was also known as the Langesundsfjord. The fjord stretches from the opening to Langesundsfjord in the south to the mouth of the Porsgrunn River in the north. The much smaller fjord of Gunneklevfjord opens into the Porsgrunn/Skien River and is separated from Frierfjorden by the peninsula of Herøya. The Frierfjorden narrows to a width of about at Breviksstrømmen, the mouth of the fjord, where the town of Brevik sits on the northern side and the town of Stathelle lies on the southern side. The Brevik Bridge crosses Breviksstrømmen between the two towns. A little further into the fjord the newer Grenland Bridge crosses the fjord, carrying t ...

Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first transatlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code abbreviations to denote the various individual stations on the line (for instance, AX could represent Halifax). "N" and two letters would identify U.S. Navy; "M" and two letters would be a Marconi station. On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icebreakers Of The Soviet Union
An icebreaker is a special-purpose ship or boat designed to move and 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, 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 trim. In cases of very thick ice, an icebreaker can drive its 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 ice itself, so icebreakers have a specially designed hull to d ...

Dobrynya Nikitich-class Icebreaker
''Dobrynya Nikitich'' class, also known by its Soviet designation Project 97, is a diverse series of diesel–electric icebreakers and other icebreaking vessels built in the Soviet Union. In total, 32 vessels were built in various configurations for both civilian and naval service in the 1960s, 1970s and early 1980s, and several remain in service in Russia . Western sources refer to the Project 97 vessels using two different names: ''Dobrynya Nikitich'' class for the various icebreaker variants and more heavily-modified derivative designs, and Ivan Susanin-class patrol ship, ''Ivan Susanin'' class specifically for #Project 97P, Project 97P patrol ships. Background and construction In the mid-1950s, the Soviet Union began developing a new diesel–electric icebreaker design that could meet the needs of both civilian and naval operators. At the time, the merchant marine relied largely on ageing steam-powered icebreakers, many of which had been built during the Imperial Russia era ...

Steamship
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 19th century; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for ''paddle steamer'' or "SS" for ''screw steamer'' (using a propeller or screw). As paddle steamers became less common, "SS" is incorrectly assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for ''motor vessel'', so it is not correct to use "SS" for most modern vessels. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was ...

Triple-expansion Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) Cylinder (engine), cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP) cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP (Arthur Woolf, Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" ...

Vladivostok
Vladivostok ( ; , ) is the largest city and the administrative center of Primorsky Krai and the capital of the Far Eastern Federal District of Russia. It is located around the Zolotoy Rog, Golden Horn Bay on the Sea of Japan, covering an area of , with a population of 603,519 residents Vladivostok is the second-largest city in the Far Eastern Federal District, as well as the Russian Far East, after Khabarovsk. It is located approximately from the China–Russia border and from the North Korea–Russia border. What is now Vladivostok was part of Outer Manchuria. Shortly after the signing of the Treaty of Aigun between Qing China and the Russian Empire and affirmed by the Convention of Peking – from which it is also known as the Amur Annexation – the city was founded as a Russian military outpost on July 2, 1860. In 1872, the main Russian naval base on the Pacific Ocean was transferred to the city, stimulating its growth. In 1914 the city experienced rapid growth economical ...
