RFA Fort Rosalie (A186)
RFA ''Fort Rosalie'' (A186) was an armament stores carrier of the Royal Fleet Auxiliary. She was built by United Shipyards, Montreal and initially completed as a stores ship but converted to an armament stores issuing ship at Portsmouth 1947/8. She served in the Pacific Fleet Train and remained in the Far East until 1951. She took part in Operation Grapple, the thermonuclear weapon test at Christmas Island in 1957. The ship was fitted with cargo lifts 1959/60. She was decommissioned on 1 May 1972 and laid up at Rosyth. She arrived at Castellon for scrapping on 10 February 1973. During World War II, 28 were lost to enemy action, and four were lost due to accidents. Many of the surviving 166 ships passed to the United States Maritime Commission. The last recorded scrapping was in 1985. Fort and Park ship were the Canadian equivalent of the United States, American Liberty ships. All three shared a similar design by J.L. Thompson and Sons of Sunderland, Tyne and Wear, Sunderland, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunderland, Tyne And Wear
Sunderland () is a port city in Tyne and Wear, England. It is the City of Sunderland's administrative centre and in the historic county of Durham. The city is from Newcastle-upon-Tyne and is on the River Wear's mouth to the North Sea. The river also flows through Durham roughly south-west of Sunderland City Centre. It is the only other city in the county and the second largest settlement in the North East after Newcastle upon Tyne. Locals from the city are sometimes known as Mackems. The term originated as recently as the early 1980s; its use and acceptance by residents, particularly among the older generations, is not universal. At one time, ships built on the Wear were called "Jamies", in contrast with those from the Tyne, which were known as "Geordies", although in the case of "Jamie" it is not known whether this was ever extended to people. There were three original settlements by the River's mouth which are part of the modern-day city: Monkwearmouth, settled in 674 ...

Fort Cataraqui (ship)
SS ''Fort Cataraqui'' was a North Sands-type Fort ship. The North Sands type, along with similar Park, Fort, and Canadian Liberty classes were essentially British and Canadian variants of the American Liberty and Victory classes. ''Fort Cataraqui'' is notable for being the first Allied ship to enter the port of Antwerp after the Canadian First Army cleared the Scheldt Estuary during the Battle of the Scheldt in the Second World War. The vessel was built by Davie Shipbuilding & Repair Company, in Lauzon, Quebec and was delivered in October 1942. ''Fort Cataraqui'' survived the war and was broken up in 1960 in Mobile, Alabama. During World War II, 28 were lost to enemy action, and four were lost due to accidents. Many of the surviving 166 ships passed to the United States Maritime Commission. The last recorded scrapping was in 1985, and two ships, the former and , were listed on Lloyd's Register Lloyd's Register Group Limited (LR) is a technical and professional services orga ...

Lloyd's Register
Lloyd's Register Group Limited (LR) is a technical and professional services organisation and a maritime classification society, wholly owned by the Lloyd’s Register Foundation, a UK charity dedicated to research and education in science and engineering. The organisation dates to 1760. Its stated aims are to enhance the safety of life, property, and the environment, by helping its clients (including by validation, certification, and accreditation) to improve the safety and performance of complex projects, supply chains and critical infrastructure. In July 2012, the organisation converted from an industrial and provident society to a company limited by shares, named Lloyd’s Register Group Limited, with the new Lloyd’s Register Foundation as the sole shareholder. At the same time the organisation gave to the Foundation a substantial bond and equity portfolio to assist it with its charitable purposes. It will benefit from continued funding from the group’s operating arm, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propellor
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...

Triple Expansion Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Liberty Ship
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them th ...

Montreal
Montreal ( ; officially Montréal, ) is the List of the largest municipalities in Canada by population, second-most populous city in Canada and List of towns in Quebec, most populous city in the Provinces and territories of Canada, Canadian province of Quebec. Founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built.
