MV Aorangi (1924)
MV ''Aorangi'' was a transpacific ocean liner and refrigerated cargo ship. She was launched in 1924 in Scotland and scrapped in 1953. Her regular route was between Sydney and Vancouver via Auckland, Suva and Honolulu. ''Aorangi'' was owned firstly by the Union Steam Ship Company of New Zealand (popularly known as the "Union Company"), and later by the Canadian-Australasian Line, which was jointly owned by the Union Company and Canadian Pacific. Like many Union Company ships, she was registered in London in the United Kingdom. ''Aorangi'' was a troop ship and depot ship in the Second World War. When new, ''Aorangi'' was both the largest and the swiftest motor ship in the World. She was also the largest and swiftest ship in the Union Company fleet. Background Since the first decade of the 20th century the Union Company had operated the Sydney – Vancouver mail ship route. In 1913 the Union Company introduced a new liner on the route, . She was faster and far larger than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles.

Two-stroke Diesel Engine
A two-stroke diesel engine is an internal combustion engine that uses compression ignition, with a two-stroke combustion cycle. It was invented by Hugo Güldner in 1899.Mau (1984) p.7 In compression ignition, air is first compressed and heated; fuel is then injected into the cylinder, causing it to self-ignite. The two-stroke cycle ignites the fuel to deliver a power stroke each time the piston rises and falls in the cylinder, without any need for the additional exhaust and induction strokes of the four-stroke cycle. History According to the designer of the first operational diesel engine, Imanuel Lauster, Rudolf Diesel did not originally intend using the two-stroke principle for the diesel engine. Hugo Güldner designed what is believed to be the first operational two-stroke diesel engine in 1899, and he convinced MAN, Krupp and Diesel to fund building this engine with ℳ 10,000 each. Güldner's engine had a 175 mm work cylinder, and a 185 mm scavenging cylinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motor Ship
A motor ship or motor vessel is a ship propelled by an internal combustion engine, usually a diesel engine. The names of motor ships are often prefixed with MS, M/S, MV or M/V. Engines for motorships were developed during the 1890s, and by the early 20th century, motorships began to cross the waters. History The first diesel-powered motorships were launched in 1903: the Russian (the first equipped with diesel-electric transmission) and French ''Petite-Pierre''. There is disagreement over which of the two was the first. See also * Gas turbine ship (GTS) – prefix for a jet-engine/turbine-propelled ship * Steamship (SS) – a steamship is a ship propelled by a steam engine or steam turbine. The name of steam ships are often prefixed with SS or S/S * Royal Mail Ship Royal Mail Ship (sometimes Steam-ship or Steamer), usually seen in its abbreviated form RMS, is the ship prefix used for seagoing vessels that carry mail under contract to the British Royal Mail.

World War II
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] |
Depot Ship
A depot ship is an auxiliary ship used as a mobile or fixed base for submarines, destroyers, minesweepers, fast attack craft, landing craft, or other small ships with similarly limited space for maintenance equipment and crew dining, berthing and relaxation. Depot ships may be identified as tenders in American English. Depot ships may be specifically designed for their purpose or be converted from another purpose. Function Depot ships provide services unavailable from local naval base shore facilities. Industrialized countries may build naval bases with extensive workshops, warehouses, barracks, and medical and recreation facilities. Depot ships operating within such bases may provide little more than command staff offices,Lenton (1975) pp.391-394 while depot ships operating at remote bases may perform unusually diverse support functions. Some United States Navy submarine depot ships operating in the Pacific during World War II included sailors with Construction Battalion ratings ...

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 ...

CP Ships
CP Ships was a large Canadian shipping company established in the 19th century. From the late 1880s until after World War II, the company was Canada's largest operator of Atlantic and Pacific steamships. Many immigrants travelled on CP ships from Europe to Canada. The sinking of the steamship just before World War I was the largest maritime disaster in Canadian history. The company provided Canadian Merchant Navy vessels in World Wars I and II. Twelve vessels were lost due to enemy action in World War II, including the , which was the largest ship ever sunk by a German U-boat. The company moved to a model of container shipping from passenger, freight and mail service in the 1960s due to competitive pressure from the airline industry. The company was a part of the Canadian Pacific Ltd. conglomerate. It was spun out as a separate company in 2001. In 2005, it was purchased by TUI AG and is now part of the company's Hapag-Lloyd division. The Atlantic and Pacific passenger line ...

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 ...

Ocean Liner
An ocean liner is a passenger ship primarily used as a form of transportation across seas or oceans. Ocean liners may also carry cargo or mail, and may sometimes be used for other purposes (such as for pleasure cruises or as hospital ships). Cargo vessels running to a schedule are sometimes called ''liners''. The category does not include ferry, ferries or other vessels engaged in short-sea trading, nor dedicated cruise ships where the voyage itself, and not transportation, is the primary purpose of the trip. Nor does it include tramp steamers, even those equipped to handle limited numbers of passengers. Some shipping companies refer to themselves as "lines" and their container ships, which often operate over set routes according to established schedules, as "liners". Ocean liners are usually strongly built with a high Freeboard (nautical), freeboard to withstand rough seas and adverse conditions encountered in the open ocean. Additionally, they are often designed with thicker H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transpacific Crossing
Transpacific crossings are voyages of passengers and cargo across the Pacific Ocean between Asia, Australia and the Americas. Cruises offer transpacific crossing which passes through the International Date Line. The first recorded crossing of the Pacific was the Magellan-Elcano expedition of 1521. Commercial transpacific flights have been available since 1935. History The Spanish expedition of Magellan-Elcano was the first to cross the Pacific in 1521 and the one to give the ocean its name. After discovering and crossing the Strait of Magellan in November 1520, the expedition sailed northwest across the Pacific for over three months and reached the Philippines in March 1521. Juan Sebastian Elcano would continue the expedition to complete the first world circumnavigation in 1522. The first navigator to cross the Pacific from west to east was Andres de Urdaneta, who discovered the easterly route across the Pacific from the Philippines to Mexico in 1565. The first transpacific trade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyrocompass
A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth (or another planetary body if used elsewhere in the universe) to find geographical direction automatically. The use of a gyrocompass is one of the seven fundamental ways to determine the heading of a vehicle. A gyroscope is an essential component of a gyrocompass, but they are different devices; a gyrocompass is built to use the effect of gyroscopic precession, which is a distinctive aspect of the general gyroscopic effect. Gyrocompasses are widely used for navigation on ships, because they have two significant advantages over magnetic compasses: * they find true north as determined by the axis of the Earth's rotation, which is different from, and navigationally more useful than, ''magnetic'' north, and * they are unaffected by ferromagnetic materials, such as in a ship's steel hull, which distort the magnetic field. Aircraft commonly use gyroscopic instrumen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direction Finding
Direction finding (DF), or radio direction finding (RDF), isin accordance with International Telecommunication Union (ITU)defined as radio location that uses the reception of radio waves to determine the direction in which a radio station or an object is located. This can refer to radio or other forms of wireless communication, including radar signals detection and monitoring (ELINT/ESM). By combining the direction information from two or more suitably spaced receivers (or a single mobile receiver), the source of a transmission may be located via triangulation. Radio direction finding is used in the navigation of ships and aircraft, to locate emergency transmitters for search and rescue, for tracking wildlife, and to locate illegal or interfering transmitters. RDF was important in combating German threats during both the World War II Battle of Britain and the long running Battle of the Atlantic. In the former, the Air Ministry also used RDF to locate its own fighter gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
