HMS Narwhal (S03)
HMS ''Narwhal'' (S03) was a ''Porpoise''-class submarine of the Royal Navy. She was launched on 25 October 1957. Design and construction The ''Porpoise'' class was the first class of operational submarines built for the Royal Navy after the end of the Second World War, and were designed to take advantage of experience gained by studying German Type XXI U-boats and British wartime experiments with the submarine , which was modified by streamlining and fitting a bigger battery. The ''Porpoise''-class submarines were long overall and between perpendiculars, with a beam of and a draught of . Displacement was standard and full load surfaced and submerged. Propulsion machinery consisted of two Admiralty Standard Range diesel generators rated at a total of , which could charge the submarine's batteries or directly drive the electric motors. These were rated at , and drove two shafts, giving a speed of on the surface and submerged. Eight torpedo tubes were fitted; six ...

Vickers-Armstrongs
Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977. History Vickers merged with the Tyneside-based engineering company Armstrong Whitworth, founded by William Armstrong, to become Vickers-Armstrongs. Armstrong Whitworth and Vickers had developed along similar lines, expanding into various military sectors and produced a whole suite of military products. Armstrong Whitworth were notable for their artillery manufacture at Elswick and shipbuilding at a yard at High Walker on the River Tyne. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage and Wagon (MCCW); Metro Cammell. In 1935, before rearmament began, Vickers-Armstrongs was the third-largest manufacturing emplo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
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" (or "load lines"). A mer ...

Ships Built In Barrow-in-Furness
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were con ...

Portland Harbour
Portland Harbour is located beside the Isle of Portland, Dorset, on the south coast of England. Construction of the harbour began in 1849; when completed in 1872, its surface area made it the largest man-made harbour in the world, and remains one of the largest in the world today. It is naturally protected by Portland to the south, Chesil Beach to the west and mainland Dorset to the north. It consists of four breakwaters — two southern and two northern. These have a total length of and enclose approximately of water. Portland Harbour was built by the Admiralty as a facility for the Royal Navy (though access was also available to merchant ships); on 11 December 1923 it was formally designated HM Naval Base (HMNB) Portland, and continued to serve as such until closure in 1995. History Creation of harbour of refuge (1844–1872) The original harbour was naturally protected by the south coast of England, Chesil Beach and the Isle of Portland, providing refuge for ships aga ...

North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though some perhaps semi-permanent gravel banks lie slightly clos ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Campbeltown
Campbeltown (; gd, Ceann Loch Chille Chiarain or ) is a town and former royal burgh in Argyll and Bute, Scotland. It lies by Campbeltown Loch on the Kintyre peninsula. Campbeltown became an important centre for Scotch whisky, and a busy fishing port. The 2018 population estimate was 4,600 indicating a reduction since the 2011 census. History Originally known as Kinlochkilkerran (an anglicization of the Gaelic, which means 'head of the loch by the kirk of Ciarán'), Campbeltown was renamed in the 17th century as ''Campbell's Town'' after Archibald Campbell ( Earl of Argyle) was granted the site in 1667. Campbeltown Town Hall was completed in 1760. Whisky Campbeltown is one of five areas in Scotland categorised as a distinct malt whisky producing region, and is home to the Campbeltown single malts. At one point it had over 30 distilleries and proclaimed itself "the whisky capital of the world". However, a focus on quantity rather than quality, and the combination of Prohibiti ...

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 ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
