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.

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 ...

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 ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
50 Let Pobedy
''50 Let Pobedy'' (russian: 50 лет Победы; "50 Years of Victory", referring to the anniversary of victory of the Soviet Union in World War II) is a Russian nuclear-powered icebreaker. History Construction on project no. 10521 started on 4 October 1989, at the Baltic Works in Leningrad (now Saint Petersburg), USSR. Originally the ship was named ''Ural''. Work was halted in 1994 for lack of funds, so that the actual fiftieth anniversary of Victory Day in 1995, after which she was named, found the ship in an abandoned state. Construction was restarted in 2003. On 30 November 2004, a fire broke out on the ship. All workers aboard the vessel had to be evacuated while the fire crews battled the fire for some 20 hours before getting it under control; one worker was sent to the hospital. She was finally completed in the beginning of 2007, after the 60th Anniversary. The icebreaker sailed into the Gulf of Finland for two weeks of sea trials on 1 February 2007. Upon completing ...

Nuclear-powered Icebreaker
A nuclear-powered icebreaker is an icebreaker with an Nuclear marine propulsion, onboard nuclear power plant that produces power for the vessel's propulsion system. , Russia is the only country that builds and operates nuclear-powered icebreakers, having built a number of such vessels to aid shipping along the Northern Sea Route since the Soviet times. Nuclear-powered icebreakers are much more powerful than their Diesel engine, diesel-powered counterparts. Although nuclear propulsion is expensive to install and maintain, very heavy fuel demands, limitations on range, and difficulty refueling in the Arctic region can make diesel vessels less practical and less economical overall for these ice-breaking duties. During the winter, the ice along the Northern Sea Route varies in thickness from . The ice in central parts of the Arctic Ocean is on average thick. Nuclear-powered icebreakers can force through this ice at speeds up to . In ice-free waters, the maximum speed of the nuclear-p ...

Arktika-class Icebreaker
The ''Arktika'' class is a Russian (formerly Soviet) class of nuclear-powered icebreakers. Formerly known as ''Project 10520 nuclear-powered icebreaker'', they were the world's largest and most powerful icebreakers until the 2016 launch of the first Project 22220 icebreaker, also named '' Arktika''. Ships of the ''Arktika'' class are owned by the federal government, but were operated by the Murmansk Shipping Company (MSCO) until 2008, when they were transferred to the fully state-owned corporation Atomflot. Of the ten civilian nuclear-powered vessels built by Russia or the Soviet Union, six were of this type. They are used for escorting merchant ships in the Arctic Ocean north of Siberia as well as for scientific and recreational expeditions to the Arctic. History On July 3, 1971, construction began on a conceptual design of a larger nuclear icebreaker, dubbed '' Arktika'', in the Baltic Shipyard in then Leningrad.Olagaard, P. Reistad, O. (April 2006).
