Round Table-class Trawler
The Round Table class was a small class of trawlers built for the British Royal Navy in 1941–1942. The class were built by two Aberdeen shipbuilding firms Hall, Russell & Company and J. Lewis & Sons Ltd. All were built to a 1936 design, the ''Star of Orkney'', by Hall, Russell & Co but were commissioned as minesweepers. Two of the class, ''Sir Galahad'' and ''Sir Lancelot'' were converted to danlayers. Ships The ships (and assigned pennant numbers) in the class were: * ''Sir Agravaine'' (T230) launched 5 March 1942 * ''Sir Galahad'' (T226) launched 18 December 1941 * ''Sir Gareth'' (T227) launched 19 January 1942 * ''Sir Geraint'' (T240) launched 15 April 1942 * ''Sir Kay'' (T241) launched 26 October 1942 * ''Sir Lamorack'' (T242) launched 23 November 1942 * ''Sir Lancelot'' (T228) launched 4 December 1941 * ''Sir Tristram'' (T229) launched 17 January 1942 See also * Trawlers of the Royal Navy Naval trawlers were purpose-built or requisitioned and operated by the ...

Hall, Russell & Company
Hall, Russell & Company, Limited was a shipbuilder based in Aberdeen, Scotland. History Brothers James and William Hall, Thomas Russell, a Glasgow engineer, and James Cardno Couper founded the company in 1864 to build steam engines and boilers. In 1867 the company built its first ship, the ''Kwang Tung'', for the Imperial Chinese Navy. Like most shipyards of their era, Hall Russell built ships first using iron and later changing to steel. In 1944–45 Hall, Russell built five coasters under sub-contract for the Burntisland Shipbuilding Company of Fife: hull numbers 773, 776, 781, 785 and 788. In 1956–57 Hall, Russell built two more coasters for Burntisland: hull 750 launched as SS ''Winga'' and hull 857 launched as William Cory & Son's MV ''Corsea''. In 1977 the company became part of the nationalised British Shipbuilders Corporation, before being returned to the private sector in 1986. Having been placed in receivership in 1988, it came under the ownership of A&P Appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danlayer
A danlayer was a type of vessel assigned to minesweeping flotillas during and immediately after World War II. They were usually small trawlers, fitted for the purpose of laying dans. A dan is a marker buoy which consists of a long pole moored to the seabed and fitted to float vertically, usually with a coded flag at the top. Dan laying was an important part of minesweeping, and boats were fitted specifically for this purpose. The task of a danlayer was to follow the minesweepers as they worked an area, and lay the dans which defined the area swept and made it obvious where the clear channels were. This would also help the minesweepers cover areas accurately without gaps and unnecessary overlaps.McDougall RJ, ''New Zealand Naval Vessels'', p. 55. Wellington, NZ: Government Printing Office, 1989. A danlayer worked with a minesweeper flotilla when large areas of sea were to be clear-swept.

Naval Trawlers Of The United Kingdom
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications ( ...

Minesweepers Of The Royal Navy
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

Trawlers Of The Royal Navy
Naval trawlers were purpose-built or requisitioned and operated by the Royal Navy (RN), mainly during World Wars I and II. Vessels built to Admiralty specifications for RN use were known as Admiralty trawlers. All trawlers operated by the RN, regardless of origin, were typically given the prefix HMT, for "His Majesty's Trawler". Summary First World War The trawler Viola, built in 1906 at Hull and requisitioned September 1914 is the oldest surviving steam trawler in the world. She is currently beached at Grytviken in South Georgia, though there are currently plans to return her to Hull. Second World War Requisitioned trawlers There were also 215 trawlers of no specific class These were commercial trawlers that the Admiralty requisitioned. The Royal Navy classified requisitioned trawlers by manufacturer, although such classes were more diverse than traditional naval classifications. Seventy-two requisitioned trawlers were lost.

RV Sir Lancelot
RV ''Sir Lancelot'' (LT263) was a fisheries research vessel that was operated by the Directorate of Fisheries, now known as the Centre for Environment, Fisheries and Aquaculture Science (Cefas). It was based at the port of Lowestoft and was originally ordered by the Admiralty as one of eight Round Table-class trawlers during World War II HMS ''Sir Lancelot'' (T228) took part in Operation Neptune, the D-Day landings in June 1944, attached to the 14th Minesweeping flotilla in Force U. She was primarily responsible for marking swept passages to Utah Beach.Operation Neptune the Minesweeping Operation 5–6 June 1944, by David Verghese. http://www.mcdoa.org.uk/operation_neptune_minesweeping.htm Accessed 18 May 2018. After the war and conversion to a civilian trawler ''Sir Lancelot'' came into service as a research vessel in December 1946. In 1962, she was sold to Mrs Karin Meta Alexa Husseini, Hamburg and renamed 'Hair-Ed-Din Barbarossa'. Construction and wartime history The ship ...

HMS Sir Galahad (T226)
HMS ''Sir Galahad'' was a trawler built for the British Royal Navy in 1941. Post war it was sold into civilian service and was wrecked in 1957 after running aground off the Isle of Mull. Construction and war service The vessel was built by Hall, Russell & Company of Aberdeen to a 1936 design of the same company. Although the design was for a trawler the ship was commissioned as a minesweeper (Pennant number T226). Launched in December 1941 she was the second member of the Round Table class. In March 1943 the ''Sir Galahad'' was one of the first ships to respond when the aircraft carrier sank in the River Clyde. In 1944, having been converted to a danlayer, ''Sir Galahad'' was attached to the 14th Minesweeping Flotilla, part of Force U. The 14th Minesweeping Flotilla took part in Operation Neptune, the maritime part of the Normandy Landings. Post war Decommissioned in February 1946, the ship was sold in April of the same year to the Walker Steam Trawling & Fishing Co Ltd ...

Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any penna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aberdeen
Aberdeen (; sco, Aiberdeen ; gd, Obar Dheathain ; la, Aberdonia) is a city in North East Scotland, and is the third most populous city in the country. Aberdeen is one of Scotland's 32 local government council areas (as Aberdeen City), and has a population estimate of for the city of Aberdeen, and for the local council area making it the United Kingdom's 39th most populous built-up area. The city is northeast of Edinburgh and north of London, and is the northernmost major city in the United Kingdom. Aberdeen has a long, sandy coastline and features an oceanic climate, with cool summers and mild, rainy winters. During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, which may sparkle like silver because of its high mica content. Since the discovery of North Sea oil in 1969, Aberdeen has been known as the offshore oil capital of Europe. Based upon the discovery of prehistoric villages around the mouths of the ...
