Moskva (2007 Icebreaker)
''Moskva'' ( rus, Москва; literally: Moscow) is a Russian Project 21900 icebreaker, Project 21900 diesel-electric icebreaker. Built at Baltic Shipyard in 2008, she was the first non-nuclear-powered icebreaker built in Russia after the dissolution of the Soviet Union. ''Moskva'' has an identical sister ship, Sankt-Peterburg (icebreaker), ''Sankt-Peterburg'', built in 2009. In addition, three icebreakers of slightly upgraded design (Vladivostok (2014 icebreaker), ''Vladivostok'', Murmansk (2015 icebreaker), ''Murmansk'' and Novorossiysk (icebreaker), ''Novorossiysk'') were built in 2015–2016. Development and construction In July 2004, the Saint Petersburg-based Baltic Shipyard won an international tender for the construction of two 16-megawatt diesel-electric icebreakers for Rosmorport, a state-owned company established in 2003 to manage Russia's port infrastructure and operate its fleet of diesel-powered icebreakers. Although the shipyard had built five Arktika-class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moscow
Moscow ( , US chiefly ; rus, links=no, Москва, r=Moskva, p=mɐskˈva, a=Москва.ogg) is the capital and largest city of Russia. The city stands on the Moskva River in Central Russia, with a population estimated at 13.0 million residents within the city limits, over 17 million residents in the urban area, and over 21.5 million residents in the metropolitan area. The city covers an area of , while the urban area covers , and the metropolitan area covers over . Moscow is among the world's largest cities; being the most populous city entirely in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow grew to become a prosperous and powerful city that served as the capital of the Grand Duchy that bears its name. When the Grand Duchy of Moscow evolved into the Tsardom of Russia, Moscow remained the political and economic center for most of the Tsardom's history. When th ...

Sankt-Peterburg (icebreaker)
''Sankt-Peterburg'' ( rus, Санкт-Петербург; literally: Saint Petersburg) is a Russian diesel-electric icebreaker. She was built at Baltic Shipyard in 2009 as the second vessel for Project 21900, the first series of non-nuclear icebreakers built in Russia after the dissolution of the Soviet Union. She has an identical sister ship, the 2008-built ''Moskva''. Following the construction of ''Sankt-Peterburg'', three icebreakers of slightly upgraded design ( ''Vladivostok'', ''Murmansk'' and ''Novorossiysk'') were built in 2015–2016. Development and construction In July 2004, the Saint Petersburg-based Baltic Shipyard won an international tender for the construction of two 16-megawatt diesel-electric icebreakers for Rosmorport, a state-owned company established in 2003 to manage Russia's port infrastructure and operate its fleet of diesel-powered icebreakers. Although the shipyard had built five ''Arktika''-class nuclear-powered icebreakers in 1975–199 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Generator
A diesel generator (DG) (also known as a diesel Genset) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. This is a specific case of engine generator. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas. Diesel generating sets are used in places without connection to a power grid, or as an emergency power supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support, and export to the power grid. Diesel generator size is crucial to minimize low load or power shortages. Sizing is complicated by the characteristics of modern electronics, specifically non-linear loads. In size ranges around 50 MW and above, an open cycle gas turbine is more efficient at full load than an array of diesel engines, and far more compact, with comparable capital costs; but for regular part-loading, ...

Ice Class
Ice class refers to a notation assigned by a classification society or a national authority to denote the additional level of strengthening as well as other arrangements that enable a ship to navigate through sea ice. Some ice classes also have requirements for the ice-going performance of the vessel. Significance of ice class Not all ships are built to an ice class. Building a ship to an ice class means that the hull must be thicker, and more scantlings must be in place. Sea chests may need to be arranged differently depending on the class. Sea bays may also be required to ensure that the sea chest does not become blocked with ice. Most of the stronger classes require several forms of rudder and propeller protection. Two rudder pintles are usually required, and strengthened propeller tips are often required in the stronger ice classes. More watertight bulkheads, in addition to those required by a ship's normal class, are usually required. In addition, heating arrangemen ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...

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 ...
