HMS Dasher (1895)
HMS ''Dasher'' was a which served with the Royal Navy. She was built by Yarrow Shipbuilders in 1895, served in home waters and was sold in 1911. Construction and design On 12 October 1893, the British Admiralty placed an order for three torpedo boat destroyers (, ''Dasher'' and ) with the shipbuilder Yarrow under the 1893–1894 shipbuilding programme for the Royal Navy as a follow-on to the two prototype destroyers ( and ) ordered from Yarrows under the 1892–1893 programme. The Admiralty did not specify a standard design for destroyers, laying down broad requirements, including a trial speed of , a "turtleback" forecastle and armament, which was to vary depending on whether the ship was to be used in the torpedo boat or gunboat role. As a torpedo boat, the planned armament was a single QF 12 pounder 12 cwt ( calibre) gun on a platform on the ship's conning tower (in practice the platform was also used as the ship's bridge), together with a secondary gun armament of three ...

Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMNB Devonport
His Majesty's Naval Base, Devonport (HMNB Devonport) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Portsmouth) and is the sole nuclear repair and refuelling facility for the Royal Navy. The largest naval base in Western Europe, HMNB Devonport is located in Devonport, in the west of the city of Plymouth, England. The base began as Royal Navy Dockyard in the late 17th century, but shipbuilding ceased at Devonport in the early 1970s, although ship maintenance work has continued. The now privatised maintenance facilities are operated by Babcock International Group, who took over the previous owner Devonport Management Limited (DML) in 2007. DML had been running the Dockyard since privatisation in 1987. From 1934 until the early 21st century the naval barracks on the site was named HMS ''Drake'' (it had previously been known as HMS ''Vivid'' after the base ship of the same name). The name HMS ''Drake'' and its c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimmeridge
Kimmeridge () is a small village and civil parish on the Isle of Purbeck, a peninsula on the English Channel coast in Dorset, England. It is situated about south of Wareham and west of Swanage. In 2013 the estimated population of the civil parish was 90. Kimmeridge is a coastal parish and its coastline forms part of the Jurassic Coast, a World Heritage Site. The coast is also part of a Site of Special Scientific Interest, and the whole parish is part of the Dorset Area of Outstanding Natural Beauty. Kimmeridge is the type locality for Kimmeridge Clay, the geological formation that covers most of the parish. Within the clay are bands of bituminous shale, which in the history of the village have been the focus of several attempts to create an industrial centre. An oil well has operated on the shore of Kimmeridge Bay since 1959. The village is the origin of the name of the Kimmeridgian stage of the Late Jurassic. The roughly semi-circular Kimmeridge Bay is southwest of Kimme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonport, Plymouth
Devonport ( ), formerly named Plymouth Dock or just Dock, is a district of Plymouth in the English county of Devon, although it was, at one time, the more important settlement. It became a county borough in 1889. Devonport was originally one of the "Three Towns" (along with Plymouth and East Stonehouse); these merged in 1914 to form what would become in 1928 the City of Plymouth. It is represented in the Parliament of the United Kingdom as part of the Plymouth Sutton and Devonport constituency. Its elected Member of Parliament (MP) is Luke Pollard, who is a member of the Labour Party. The population of the ward at the 2011 census was 14,788. History Plymouth Dock In 1690 the Admiralty gave a contract to Robert Waters from Portsmouth to build a stone dock at Point Froward on the east bank of the Hamoaze at the mouth of the River Tamar. Plymouth Dock, as Devonport was originally called, began around 1700 as a small settlement to house workers employed on the new naval base tha ...

Chatham Dockyard
Chatham Dockyard was a Royal Navy Dockyard located on the River Medway in Kent. Established in Chatham in the mid-16th century, the dockyard subsequently expanded into neighbouring Gillingham (at its most extensive, in the early 20th century, two-thirds of the dockyard lay in Gillingham, one-third in Chatham). It came into existence at the time when, following the Reformation, relations with the Catholic countries of Europe had worsened, leading to a requirement for additional defences. Over 414 years Chatham Royal Dockyard provided more than 500 ships for the Royal Navy, and was at the forefront of shipbuilding, industrial and architectural technology. At its height, it employed over 10,000 skilled artisans and covered . Chatham dockyard closed in 1984, and of the Georgian dockyard is now managed as the Chatham Historic Dockyard visitor attraction by the Chatham Historic Dockyard Trust.

Earle's Shipbuilding
Earle's Shipbuilding was an engineering company that was based in Hull, East Riding of Yorkshire, England from 1845 to 1932. Earle Brothers The company was started in Hull in 1845 by two brothers, Charles and William Earle. The firm was made up of engineers and focussed on shipbuilding and repair. Its most notable association was with the Wilson Line, for whom the yard produced many ships. Earle's also built vessels for many other British shipping firms, especially those operating on North Sea routes such as the Great Eastern Railway and the Hull & Netherlands Steamship Co. Ltd. In 1871, Earle's was restructured as a joint-stock company and for a short time Sir Edward James Reed served as its chairman and managing director. Earle's built two steam yachts for Tsarevitch Alexander: ''Slavanka'' in 1873 and ''Czarevna'' in 1874. Also in 1874 Earle's built the unsuccessful , Sir Henry Bessemer's experimental swinging-cabin paddle steamer, which made its maiden (and only) publi ...

Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Trials
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 used t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...
