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.

Kara Sea
The Kara Sea (russian: Ка́рское мо́ре, ''Karskoye more'') is a marginal sea, separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya, and from the Laptev Sea to the east by the Severnaya Zemlya archipelago. Ultimately the Kara, Barents and Laptev Seas are all extensions of the Arctic Ocean north of Siberia. The Kara Sea's northern limit is marked geographically by a line running from Cape Kohlsaat in Graham Bell Island, Franz Josef Land, to Cape Molotov (Arctic Cape), the northernmost point of Komsomolets Island in Severnaya Zemlya. The Kara Sea is roughly long and wide with an area of around and a mean depth of . Its main ports are Novy Port and Dikson and it is important as a fishing ground although the sea is ice-bound for all but two months of the year. The Kara Sea contains the East-Prinovozemelsky field (an extension of the West Siberian Oil Basin), containing significant undeveloped petroleum and natural gas. In 2014, ...

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 A sternpost is the upright structural member or post at the stern of a (generally wooden) ship or a boat, to which are attached the transoms and the rearmost left corner part of the stern. The sternpost may either be completely vertical or m ..., 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, natural ...

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 A marina (from Spanish , Portuguese and Italian : ''marina'', "coast" or "shore") is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships o ... 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 oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 li ... [...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 (9 May), 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 2 ...

Nuclear-powered Icebreaker
A nuclear-powered icebreaker is an icebreaker with an 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-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-powered icebreakers is as much as . Use ...

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).
