Evpatiy Kolovrat (icebreaker)
''Evpatiy Kolovrat'' (russian: italic=yes, Евпатий Коловрат) is a Russian icebreaker built at the Almaz Shipbuilding Company for the Russian Navy. The vessel is scheduled to enter service with the Pacific Fleet in 2023. Development and construction In the mid-2010s, the Ministry of Defence of the Russian Federation announced that a fleet of new auxiliary icebreakers would be built for the Russian Navy as part of the ongoing fleet renewal program to replace Soviet-era vessels. However, the initial plans for the construction of four Project 21180 icebreakers was revised after the lead ship, ''Ilya Muromets'', turned out to be too expensive. As a response to this, Vympel Design Bureau developed a revised design, 21180M, with about two thirds of the displacement and more limited functionality compared to the bigger vessel. The construction of the Project 21180M icebreaker, estimated to cost between 5 and 6 billion rubles, was awarded to the Saint Petersburg-based ...

Icebreaker
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 ...

Bow Thruster
Manoeuvering thruster (bow thruster or stern thruster) is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect. A stern thruster is of the same principle, fitted at the stern. Large ships might have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by electric motors, but some are hydraulically powered. These bow thrusters, also known as tunnel thrusters, may allow the ship to doc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

The Tale Of The Destruction Of Ryazan
''The Tale of the Destruction of Riazan'' (russian: Повесть о разорении Рязани Батыем) is an early Russian work about the capture of the city of Ryazan by the Mongols in 1237. Historical background Before the events described in the tale, the Principality of Ryazan operated as a rather prosperous border settlement-area - actively engaged in trade along the rivers Oka and Volga to the east and by the river Don and the Black Sea to the south. Archeological evidence suggests lively trading relationships with the Northern Caucasus and with peoples of the Black Sea coast. Crafts were relatively well developed, especially famous being Ryazan jewelry-making. The principality often became involved in conflicts with neighboring Chernigov and Vladimir; by the time of the Mongol invasion their relationships were relatively peaceful. Ryazan was first mentioned in a chronicle of 1096 in connection with the move of Prince Oleg I Sviatoslavovich of Chernigov (also ...
