Soviet Destroyer Lenin
''Lenin'' (Russian: Ленин) was a built for the Imperial Russian Navy during World War I under the name of ''Kapitan Izylmetev'' (Russian: Капитан Изыльметьев). Completed in 1916, she served with the Baltic Fleet. The ship was taken over by the Bolsheviks during the October Revolution in 1917 and renamed ''Lenin'' five years later. Design and description The ''Leytenant Ilin''-class ships were designed as an improved version of the .Budzbon, p. 310 The ships normally displaced and at full load. They measured long overall with a beam of , and a draft of . The ''Leytenant Ilin''s were propelled by two Brown-Boveri- Parsons steam turbines, each driving one propeller using steam from four Normand-Vulcan boilers. The turbines were designed to produce a total of for an intended maximum speed of using forced draft.Verstyuk & Gordeyev, p. 43 On ''Kapitan Izylmetev''s sea trials, she only reached from .

Russian Empire
The Russian Empire was an empire that spanned most of northern Eurasia from its establishment in November 1721 until the proclamation of the Russian Republic in September 1917. At its height in the late 19th century, it covered about , roughly one-sixth of the world's landmass, making it the list of largest empires, third-largest empire in history, behind only the British Empire, British and Mongol Empire, Mongol empires. It also Russian colonization of North America, colonized Alaska between 1799 and 1867. The empire's 1897 census, the only one it conducted, found a population of 125.6 million with considerable ethnic, linguistic, religious, and socioeconomic diversity. From the 10th to 17th centuries, the Russians had been ruled by a noble class known as the boyars, above whom was the tsar, an absolute monarch. The groundwork of the Russian Empire was laid by Ivan III (), who greatly expanded his domain, established a centralized Russian national state, and secured inde ...

Normal Displacement
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has three ...

Stern
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night. Sterns on European and American wooden sailing ships began with two principal forms: the ''square'' or ''transom'' stern and the ''elliptical'', ''fantail'', or ''merchant'' stern, and were developed in that order. The hull sections of a sailing ship located before the stern were composed of a series of U-shaped rib-like frames set in a sloped or "cant" arrangement, with the last frame before the stern being called the ''fashion timber(s)'' or ''fashion piece(s)'', so called for "fashioning" the after part of the ship. This frame i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck (ship), deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase "Wiktionary:before the mast, before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow (ship), bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main Mast (sailing), mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as th ...

Fuel Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel, and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat ( heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Trials
A sea trial or trial trip is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forced Draft
In a water boiler, draft is the difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow. Types of draft Drafts are produced by the rising combustion gases in the stack, flue, or by mechanical means. For example, a boiler can be put into four categories: natural, induced, balanced, and forced. *Natural draft: When air or flue gases flow due to the difference in density of the hot flue gases and cooler ambient gases. The difference in density creates a pressure differential that moves the hotter flue gases into the cooler surroundings. * Forced draft: When air or flue gases are maintained above atmospheric pressure. Normally it is done with the help of a forced draft fan. * Induced draft: When air or flue gases flow under the effect of a gradually decreasing pressure below atmospheric pre ...

Normand Boiler
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power Steamship, ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler. The fundamental characteristic of the "three-drum" design is the arrangement of a steam drum above two Glossary of boiler terms#Water drum, water drums, in a triangular layout. Water tubes fill in the two sides of this triangle between the drums, and the Industrial furnace, furnace is in the centre. The whole assembly is then enclosed in a casing, leading to the exhaust flue. Firing can be by either coal or oil. Many coal-fired boilers used multiple Glossary of boiler terms#Firedoor, firedoors and teams of Fireman (steam engine), stokers, often from both ends. Development Development of the three-drum boiler began in the late 19th century, with the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parsons Marine Steam Turbine Company
Parsons Marine Steam Turbine Company was a United Kingdom of Great Britain and Ireland, British engineering company based on the River Tyne at Wallsend, North East England. History Charles Algernon Parsons founded the company in 1897 with £500,000 of capital. It specialised in building the steam turbine engines that he had invented for marine use. The first vessel powered by a Parsons turbine was ''Turbinia'', launched in 1894. The successful demonstration of this vessel led to the creation of the company and the building of engines for the first two turbine-powered destroyers for the Royal Navy, and , launched in 1899. Although both these vessels came to grief, the new engines were not to blame, and the British Admiralty, Admiralty was convinced. Parsons' son became a director in the company and was replaced during the First World War by his daughter Rachel Mary Parsons, Rachel Parsons. Parsons turbines powered the Royal Navy's first turbine powered battleship, , and the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown, Boveri & Cie
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Baden bei Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1988 BBC merged with ASEA to form ABB. Early history of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network. Activity in Britain Brown Boveri's early activities included manufac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...
