SS Ranchi
SS ''Ranchi'' was Peninsular and Oriental Steam Navigation Company "R"-class steam ocean liner that was built in 1925 and scrapped in 1953. From 1939 to 1943 she was the Royal Navy armed merchant cruiser HMS ''Ranchi''. From 1943 to 1947 she was a troop ship for the Ministry of War Transport and post-war Ministry of Transport. Building and technical data Hawthorn Leslie and Company of Hebburn, County Durham built ''Ranchi'' for P&O. Her yard number was 534. She was launched on 24 January 1925 and completed on 29 July. She was long and had a beam of . Her gross register tonnage was 16,738, and as built her net register tonnage was 8,850. P&O's "R"-Class included ''Ranchi''s sister ships , and , all built in 1924 and 1925. Like her sisters ''Ranchi'' had quadruple-expansion steam engines, but unlike her sisters she also had low-pressure steam turbines to re-use exhaust steam from her reciprocating engines. The turbines were coupled to her propeller shafts by double reducti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Net Register Tonnage
Net register tonnage (NRT, nrt, n.r.t.) is a ship's cargo volume capacity expressed in "register tons", one of which equals to a volume of . It is calculated by subtracting non-revenue-earning spaces i.e. spaces not available for carrying cargo, for example engine rooms, fuel tanks and crew quarters, from the ship's gross register tonnage.Units and Systems of Measurement Their Origin, Development, and Present Status . National Institute of Standards and Technology. Net tonnage is thus used in situations where a vessel's earning capacity is important, rather than its mere size. Net register tonnage is not a measure of the weight of the ship or its cargo, and should not be confused with terms such as |

Department For Transport
The Department for Transport (DfT) is a department of His Majesty's Government responsible for the English transport network and a limited number of transport matters in Scotland, Wales and Northern Ireland that have not been devolved. The department is run by the Secretary of State for Transport, currently (since 25 October 2022) Mark Harper. The expenditure, administration and policy of the Department for Transport are scrutinised by the Transport Committee. History The Ministry of Transport was established by the Ministry of Transport Act 1919 which provided for the transfer to the new ministry of powers and duties of any government department in respect of railways, light railways, tramways, canals and inland waterways, roads, bridges and ferries, and vehicles and traffic thereon, harbours, docks and piers. In September 1919, all the powers of the Road Board, the Ministry of Health, and the Board of Trade in respect of transport, were transferred to the new min ...

Ministry Of War Transport
The Ministry of War Transport (MoWT) was a department of the British Government formed early in the Second World War to control transportation policy and resources. It was formed by merging the Ministry of Shipping and the Ministry of Transport, bringing responsibility for both shipping and land transport to a single department, and easing problems of co-ordination of transport in wartime. The MoWT was founded on 1 May 1941, when Lord Leathers was appointed Minister of War Transport. Following the general election of July 1945, Alfred Barnes was appointed Minister of War Transport, remaining in the post after the department was renamed the Ministry of Transport in April 1946. Divisions The jurisdiction of the MoWT covered all forms of transportation and it inherited numerous and varied responsibilities from its parent organisations. From the Ministry of Shipping these included: * Allocation of Tonnage Division, responsible for the provision of shipping, other than liners, bu ...

Ocean Liner
An ocean liner is a passenger ship primarily used as a form of transportation across seas or oceans. Ocean liners may also carry cargo or mail, and may sometimes be used for other purposes (such as for pleasure cruises or as hospital ships). Cargo vessels running to a schedule are sometimes called ''liners''. The category does not include ferries or other vessels engaged in short-sea trading, nor dedicated cruise ships where the voyage itself, and not transportation, is the primary purpose of the trip. Nor does it include tramp steamers, even those equipped to handle limited numbers of passengers. Some shipping companies refer to themselves as "lines" and their container ships, which often operate over set routes according to established schedules, as "liners". Ocean liners are usually strongly built with a high freeboard to withstand rough seas and adverse conditions encountered in the open ocean. Additionally, they are often designed with thicker hull plating than is found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steamship
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for ''paddle steamer'' or "SS" for ''screw steamer'' (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for ''motor vessel'', so it is not correct to use "SS" for most modern vessels. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in hu ...

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence airc ...
