Royal Navy Dockyard
Royal Navy Dockyards (more usually termed Royal Dockyards) were state-owned harbour facilities where ships of the Royal Navy were built, based, repaired and refitted. Until the mid-19th century the Royal Dockyards were the largest industrial complexes in Britain. From the reign of Henry VII up until the 1990s, the Royal Navy had a policy of establishing and maintaining its own dockyard facilities (although at the same time, as continues to be the case, it made extensive use of private shipyards, both at home and abroad). Portsmouth was the first Royal Dockyard, dating from the late 15th century; it was followed by Deptford, Woolwich, Chatham and others. By the 18th century, Britain had a string of these state-owned naval dockyards, located not just around the country but across the world; each was sited close to a safe harbour or anchorage used by the fleet. Royal Naval Dockyards were the core naval and military facilities of the four Imperial fortresses - colonies which ena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rosyth Dockyard
Rosyth Dockyard is a large Royal Navy Dockyard, naval dockyard on the Firth of Forth at Rosyth, Fife, Scotland, owned by Babcock Marine, which formerly undertook refitting of Royal Navy surface vessels and submarines. Before its privatisation in the 1990s it was formerly the Royal Naval Dockyard Rosyth. Its primary role now is the dismantling of decommissioned nuclear submarines. It is also the integration site for the Royal Navy's newest aircraft carriers, the as well as the Type 31 frigate, Type 31 Frigate. History Construction of the dockyard by civil engineers Easton, Gibb & Son commenced in 1909. At the time, the Royal Navy was strengthening its presence along the eastern seaboard of Great Britain due to a Anglo-German naval arms race, naval arms race with Germany. First World War * In 1903 approval was given with an estimated cost of £3 million for "works" and £250,000 for machinery spread over 10 years. The site consisted of of land, of foreshore, and the main bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plymouth Naval Base And Surrounding Area
Plymouth ( ) is a port city and unitary authority in Devon, South West England. It is located on Devon's south coast between the rivers Plym and Tamar, about southwest of Exeter and southwest of London. It is the most populous city in Devon. Plymouth's history extends back to the Bronze Age, evolving from a trading post at Mount Batten into the thriving market town of Sutton, which was formally re-named as Plymouth in 1439 when it was made a borough. The settlement has played a significant role in English history, notably in 1588 when an English fleet based here defeated the Spanish Armada, and in 1620 as the departure point for the Pilgrim Fathers to the New World. During the English Civil War, the town was held by the Parliamentarians and was besieged between 1642 and 1646. In 1690 a dockyard was established on the River Tamar for the Royal Navy and Plymouth grew as a commercial shipping port throughout the Industrial Revolution. After absorbing nearby settlements in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fitted Out
Fitting out, or outfitting, is the process in shipbuilding that follows the float-out/launching of a vessel and precedes sea trials. It is the period when all the remaining construction of the ship is completed and readied for delivery to her owners. Since most of the fitting-out process is interior work, this stage can overlap with latter stages, such as the sea trials. Launching or floating After a vessel has been floated (in contemporary shipbuilding) or launched (in traditional shipbuilding), it is then towed out of its drydock and moored at a fitting-out berth.The Fairfield Shipbuilding and Engineering Works: History of the Company: Review of Its Productions; and Description of the Works'. Fairfield Ship Building & Engineering Company, 1909. 108. While still afloat, its construction is then continued. Depending on the type of vessel, fitting-out can last weeks or many months. Vessels with comparatively little space for human occupation, such as oil tankers, bulk carriers an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Dock
The word dock () in American English refers to one or a group of human-made structures that are involved in the handling of boats or ships (usually on or near a shore). In British English, the term is not used the same way as in American English; it is used to mean the area of water that is next to or around a wharf or quay. The exact meaning varies among different variants of the English language. "Dock" may also refer to a dockyard (also known as a shipyard) where the loading, unloading, building, or repairing of ships occurs. History The earliest known docks were those discovered in Wadi al-Jarf, an ancient Egyptian harbor, of Pharaoh Khufu, dating from c.2500 BC located on the Red Sea coast. Archaeologists also discovered anchors and storage jars near the site. A dock from Lothal in India dates from 2400 BC and was located away from the main current to avoid deposition of silt. Modern oceanographers have observed that the ancient Harappans must have possessed great k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ropewalk
A ropewalk is a long straight narrow lane, or a covered pathway, where long strands of material are laid before being twisted into rope. Due to the length of some ropewalks, workers may use bicycles to get from one end to the other. Many ropewalks were in the open air, while others were covered only by roofs. Ropewalks historically frequently caught fire, as hemp dust ignites easily and burns fiercely. Rope was essential in sailing ships and the standard length for a British Naval Rope was . A sailing ship such as required of rope. Rope-making technology Natural fiber, Natural fibres are short in length, and so have to be twisted together into different fibres, starting at different points along the construction, to hold each other together. From a single strand, much like wool, which can easily be torn apart, putting several together forms a line, which is far stronger. That can similarly be repeated time and again, producing a very strong rope, at the cost of weight and si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Capstan (nautical)
A capstan is a vertical-axled rotating machine developed for use on sailing ships to multiply the pulling force of sailors when hauling ropes, Nautical cable, cables, and hawsers. The principle is similar to that of the windlass, which has a horizontal axle. History The word, connected with the Old French or , from Old Provençal , from "pulley cord", from Latin , a halter, from , to take hold of, seems to have come into English (14th century) from Portuguese or Spanish shipmen at the time of the Crusades. Both device and word are considered Spanish inventions. Early form In its earliest form, the capstan consisted of a timber mounted vertically through a vessel's structure which was free to rotate. Levers, known as bars, were inserted through holes at the top of the timber and used to turn the capstan. A rope wrapped several turns around the drum was thus hauled upon. A rudimentary ratchet (device), ratchet was provided to hold the tension. The ropes were always wound i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Careening
Careening (also known as "heaving down") is a method of gaining access to the hull of a sailing vessel without the use of a dry dock. It is used for cleaning or repairing the hull. Before ship's hulls were protected from marine growth by fastening copper sheets over the surface of the hull, fouling by this growth would seriously affect the sailing qualities of a ship, causing a large amount of drag. As this growth was underwater, removing it was difficult. Beaching the vessel at high tide allowed the lower hull to be exposed for cleaning or repairs. Etymology The term, and similar terms in French, Spanish and Italian, derive from the term for a ship's keel—''carène'' (French), ''carena'' (Spanish), ''carena'' (Italian). These come from the Latin term for keel, ''carīna''. Practice The ship was grounded broadside on a steep beach at high tide or, in dockyards, moored at a permanent facility for careening known as a ''careening wharf''. A beach favoured for careening was c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Marine Propulsion
Nuclear marine propulsion is Marine propulsion, propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a Transmission (mechanics), gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built. Compared to oil- or coal-fuelled ships, nuclear propulsion offers the advantage of very long intervals of operation before refueling. All the fuel is contained within the nuclear reactor, so no cargo or supplies space is taken up by fuel, nor is space taken up by exhaust stacks or combustion air intakes. The low fuel cost is offset by high operating costs and investment in infrastructure, however, so nearly all nuclear-powered vessels are military. Power plants Basic operation of naval ship or submarine Most na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Age Of Sail
The Age of Sail is a period in European history that lasted at the latest from the mid-16th (or mid-15th) to the mid-19th centuries, in which the dominance of sailing ships in global trade and warfare culminated, particularly marked by the introduction of naval artillery, and ultimately reached its highest extent at the advent of steam power. Enabled by the advances of the related age of navigation, it is identified as a distinctive element of the early modern period and the Age of Discovery. Periodization Like most periodic eras, defining the age is inexact and serves only as a general description. The term is used differently for warships and merchant vessels. By the 14th century naval artillery was employed in Europe, documented at the Battle of Arnemuiden (1338). The 15th century saw the Iberian naval ventures all the way along the African Atlantic coast and across the Atlantic Ocean, starting the Age of Discovery. For warships, the age of sail runs roughly from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graving Docks
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History China The use of dry docks in China goes at least as far back as the 10th century A.D. In 1088, Song dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his ''Dream Pool Essays'': Europe Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. However a more recent survey by Goodchild and Forbes does not substantiate its existence. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. Renaissance ...
