Nelson-class Cruiser
The ''Nelson''-class cruisers were a pair of armoured cruisers built in the 1870s for the Royal Navy. Design and description The ''Nelson''-class ships were designed by Nathaniel Barnaby, Chief Constructor of the Royal Navy, as enlarged and improved versions of to counter the threat of enemy armoured ships encountered abroad. The ships were not much liked in service as they were deemed too weakly armoured to fight ironclad battleships and not fast enough to catch commerce-raiding cruisers. They were laid out as central battery ironclads with the armament concentrated amidships. The ''Nelson''s had a length between perpendiculars of , a beam of and a deep draught of . The ships displaced , about more than ''Shannon''. The steel-hulled ships were fitted with a ram and their crew numbered approximately 560 officers and other ranks. The ships had two 3-cylinder, inverted compound steam engines, each driving a single two-bladed, propeller, using steam provided by 10 ova ...

Hobart, Australia
Hobart ( ; Nuennonne/Palawa kani: ''nipaluna'') is the capital and most populous city of the Australian island state of Tasmania. Home to almost half of all Tasmanians, it is the least-populated Australian state capital city, and second-smallest if territories are taken into account, before Darwin, Northern Territory. Hobart is located in Tasmania's south-east on the estuary of the River Derwent, making it the most southern of Australia's capital cities. Its skyline is dominated by the kunanyi/Mount Wellington, and its harbour forms the second-deepest natural port in the world, with much of the city's waterfront consisting of reclaimed land. The metropolitan area is often referred to as Greater Hobart, to differentiate it from the City of Hobart, one of the five local government areas that cover the city. It has a mild maritime climate. The city lies on country which was known by the local Mouheneener people as nipaluna, a name which includes surrounding features such as kun ...

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 ...

Robert Napier And Sons
Messrs Robert Napier and Sons was a famous firm of Clyde shipbuilders and marine engineers at Govan, Glasgow founded by Robert Napier in 1826. It was moved to Govan for more space in 1841. His sons James and John were taken into partnership in 1853. The whole Clyde, every engineer and shipbuilder in it, was considered to have benefitted from the firm's achievements and celebrity. By the 1840s it was universally recognised as the finest in Britain. Many firms were founded by former employees.ed. W H Fraser and I Maver. ''Glasgow: 1830 to 1912'' Manchester University Press 1996 After Robert Napier's death in 1876 the plant and goodwill were sold by auction in March 1877 and purchased by a group of engineers led by the previous manager, A C Kirk. It continued to build ships and engines until 1900 when it was incorporated in William Beardmore and Company. Beginnings In 1800 Glasgow had no shipbuilding firms.

HMS Northampton (1876)
HMS ''Northampton'' was a armoured cruiser built for the Royal Navy in the 1870s. She was sold for scrap in 1905. Design and description The ''Nelson''-class ships were designed as enlarged and improved versions of HMS ''Shannon'' to counter the threat of enemy armoured ships encountered abroad. The ships had a length between perpendiculars of , a beam of and a deep draught of . ''Northampton'' displaced , about more than ''Shannon''. The steel-hulled ships were fitted with a ram and their crew numbered approximately 560 officers and other ranks.Parkes, p. 239 The ship had two 3-cylinder, inverted compound steam engines, each driving a single propeller, using steam provided by 10 oval boilers. The cylinders of the ''Northampton''s engines could be adjusted in volume to optimize steam production depending on the demand. They were troublesome throughout the ship's life and she was always about slower than her sister despite repeated efforts to improve her speed. The e ...

Glasgow
Glasgow ( ; sco, Glesca or ; gd, Glaschu ) is the most populous city in Scotland and the fourth-most populous city in the United Kingdom, as well as being the 27th largest city by population in Europe. In 2020, it had an estimated population of 635,640. Straddling the border between historic Lanarkshire and Renfrewshire, the city now forms the Glasgow City Council area, one of the 32 council areas of Scotland, and is governed by Glasgow City Council. It is situated on the River Clyde in the country's West Central Lowlands. Glasgow has the largest economy in Scotland and the third-highest GDP per capita of any city in the UK. Glasgow's major cultural institutions – the Burrell Collection, Kelvingrove Art Gallery and Museum, the Royal Conservatoire of Scotland, the Royal Scottish National Orchestra, Scottish Ballet and Scottish Opera – enjoy international reputations. The city was the European Capital of Culture in 1990 and is notable for its architectur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Randolph, Elder & Co
The Fairfield Shipbuilding and Engineering Company, Limited was a Scottish shipbuilding company in the Govan area on the Clyde in Glasgow. Fairfields, as it is often known, was a major warship builder, turning out many vessels for the Royal Navy and other navies through the First World War and the Second World War. It also built many transatlantic liners, including record-breaking ships for the Cunard Line and Canadian Pacific, such as the Blue Riband-winning sisters RMS ''Campania'' and RMS ''Lucania''. At the other end of the scale, Fairfields built fast cross-channel mail steamers and ferries for locations around the world. These included ships for the Bosporus crossing in Istanbul and some of the early ships used by Thomas Cook for developing tourism on the River Nile. John Elder & Co and predecessors Millwright Randolph & Elliott Charles Randolph founded the company as Randolph & Co. He had been an apprentice at the Clyde shipyard of Robert Napier, and at William ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brassey's Naval Annual
''The Naval Annual'' was a periodical that provided considerable text and graphic information (largely concerning the British Royal Navy) which had previously been obtainable only by consulting a wide range of often foreign language publications. During its life it underwent a number of title changes. The ''Annual'' was started by Thomas Brassey, 1st Earl Brassey, in 1886. Though often compared with '' Jane's Fighting Ships'', the two British annuals were, in fact quite different. The Brassey series began a dozen years earlier, and its special strength was the dozen or more detailed articles on naval (plus, from 1920 through 1935, merchant marine) matters, authored by experts. They covered British and other nations' naval developments ranging from the latest ships to overall policy. The first five or six Brassey volumes used a second printing colour (a light blue green) to highlight armored portions of naval vessels' hulls. Through 1949, the series was also known for its ...

Sea Trial
A sea trial 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 vessels, they are us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration i ...

Other Ranks (UK)
Other ranks (ORs) in the Royal Marines, British Army, Royal Air Force, and in the armies and air forces of many other Commonwealth countries and the Republic of Ireland, are those personnel who are not commissioned officers, usually including non-commissioned officers (NCOs). In the Royal Navy, these personnel are called " ratings" rather than "other ranks". Non-commissioned member is the equivalent term for the Canadian Armed Forces. Colloquially, members of the other ranks are known as "rankers". The term is often considered to exclude warrant officer Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned ranks, the mo ...s, and occasionally also excludes NCOs. Formally, a regiment consists of the "officers, warrant officers, non-commissioned officers and men" or the "officers, warrant officers and ...

Naval Ram
A ram was a weapon fitted to varied types of ships, dating back to antiquity. The weapon comprised an underwater prolongation of the bow of the ship to form an armoured beak, usually between 2 and 4 meters (6–12 ft) in length. This would be driven into the hull of an enemy ship to puncture, sink or disable it. Ancient rams It was possibly developed in late Bronze age Egypt, but it only became widely used in later Iron age Mediterranean galleys. The ram was a naval weapon in the Greek/ Roman antiquity and was used in such naval battles as Salamis and Actium. Naval warfare in the Mediterranean rarely used sails, and the use of rams specifically required oarsmen rather than sails in order to maneuver with accuracy and speed, and particularly to reverse the movement of a ramming ship to disentangle it from its sinking victim, lest it be pulled down when its victim sank. The Athenians were especially known for their '' diekplous'' and ''periplous'' tactics that disabled enemy shi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
