SS Tyndareus
SS ''Tyndareus'' was a British steamship that was built in 1914–15 as a cargo liner for the Blue Funnel Line of the Ocean Steamship Company. Completed during the First World War, she served as a Troopship, troop ship and was nearly sunk by a German naval mine, but without loss of life. Inter-war period, Between the wars she operated commercially in the Pacific Ocean, before returning to military service in the Second World War. Her final civil role was to carry Islamic pilgrims from Indonesia to Mecca, before being scrapped in 1960. Description The ship was long, with a beam of and a depth of . She was powered by two triple expansion steam engines, which had cylinders of 22in (56 cm), and diameter by stroke. The engines drove twin screw propellers. They were rated at 622 nominal horsepower, nhp and were built by Scotts Shipbuilding and Engineering Company. She was assessed at , .

Tyndareus
In Greek mythology, Tyndareus (; Ancient Greek: Τυνδάρεος, ''Tundáreos''; Attic Greek, Attic: Τυνδάρεως, ''Tundáreōs''; ) was a Spartan king. Family Tyndareus was the son of Oebalus (or Perieres (king of Messenia), Perieres) and Gorgophone (or Batea (mythology), Bateia). He married the Aetolian princess, Leda (mythology), Leda, by whom he became the father of Castor (mythology), Castor, Clytemnestra, Timandra (mythology), Timandra, Phoebe (mythological characters), Phoebe and Philonoe, and the stepfather of Helen of Troy and Pollux (mythology), Pollux. Mythology Early years Tyndareus had a brother named Hippocoon, who seized power and exiled Tyndareus. He was reinstated by Heracles, who killed Hippocoon and his sons. Tyndareus’ other brother was Icarius of Sparta, Icarius, the father of Penelope. Tyndareus’ wife Leda (mythology), Leda was seduced by Zeus, who disguised himself as a swan. She laid two eggs, each producing two children. When Thyestes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo Liner
A cargo liner, also known as a passenger-cargo ship or passenger-cargoman, is a type of merchant ship which carries general cargo and often passengers. They became common just after the middle of the 19th century, and eventually gave way to container ships and other more specialized carriers in the latter half of the 20th century. Characteristics A ''cargo liner'' has been defined as: A vessel which operated a regular scheduled service on a fixed route between designated ports and carries many consignments of different commodities. Cargo liners transported general freight, from raw materials to manufactures to merchandise. Many had cargo holds adapted to particular services, with refrigerator space for frozen meats or chilled fruit, tanks for liquid cargos such as plant oils, and lockers for valuables. Cargo liners typically carried passengers as well, usually in a single class. They differed from ocean liners which focussed on the passenger trade, and from tramp steamers whic ...

Nominal Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the steam ...

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 ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inter-war Period
In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days), the end of the First World War to the beginning of the Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the developed world. The indulgences of the era subsequently were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies. Politically, the era coincided with the rise of communism, starting in Russia with the October Revolution and Russian Civil War, at the end of World War I, and ended with the rise ...

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Troopship
A troopship (also troop ship or troop transport or trooper) is a ship used to carry soldiers, either in peacetime or wartime. Troopships were often drafted from commercial shipping fleets, and were unable land troops directly on shore, typically loading and unloading at a seaport or onto smaller vessels, either tenders or barges. Attack transports, a variant of ocean-going troopship adapted to transporting invasion forces ashore, carry their own fleet of landing craft. Landing ships beach themselves and bring their troops directly ashore. History Ships to transport troops were used in Antiquity. Ancient Rome used the navis lusoria, a small vessel powered by rowers and sail, to move soldiers on the Rhine and Danube. The modern troopship has as long a history as passenger ships do, as most maritime nations enlisted their support in military operations (either by leasing the vessels or by impressing them into service) when their normal naval forces were deemed insufficient fo ...

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Funnel Line
Alfred Holt and Company, trading as Blue Funnel Line, was a UK shipping company that was founded in 1866 and operated merchant ships for 122 years. It was one of the UK's larger shipowning and operating companies, and as such had a significant role in the country's overseas trade and in the First World War, First and World War II, Second World Wars. Its seafarers later went to fill various roles in the British maritime shore based establishment, including Malcolm Machlachlan, a lecturer in Glasgow and a popular author of books on Maritime business. History Foundation and expansion Alfred Holt founded the business on 16 January 1866. The main operating subsidiary was the Ocean Group plc, Ocean Steam Ship Company, which owned and operated the majority of the company's vessels. A Netherlands, Dutch subsidiary, the Nederlandsche Stoomvaart Maatschappij Oceaan, was founded in 1891, as was the East India Ocean Steam Ship Company, operated from Singapore. This latter was sold in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steamship
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for ''paddle steamer'' or "SS" for ''screw steamer'' (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for ''motor vessel'', so it is not correct to use "SS" for most modern vessels. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in hu ...
