SS Tuscania (1921)
SS ''Tuscania'' was built by Fairfield Shipbuilding and Engineering Company, and launched on 4 October 1921 for the Anchor Line. Building and description During the First World War, several large liners of Glasgow-based Anchor Line (Henderson Bros) Ltd were lost, including the earlier ''Tuscania'' of 1914. Embarking on a replacement programme even before the end of 1918, the replacement ''Tuscania'' for the Mediterranean-New York service was built by Fairfield Shipbuilding and Engineering Company at Govan, Glasgow, as yard number 595. She measured and , was long between perpendiculars by beam and had a depth of . She had six Brown-Curtis steam turbines, also made by Fairfield, driving twin screws via double reduction gearing, giving her a speed of . The ship was formally named ''Tuscania'' when launched on 4 October 1921, in the midst of the post-war economic slump, when many shipowners, Anchor Line included, had asked builders to slow or suspend building work.

Tuscania
Tuscania is a town and ''comune'' in the province of Viterbo, Lazio Region, Italy. Until the late 19th century the town was known as Toscanella. History Antiquity According to the legend, Tuscania was founded by Aeneas' son, Ascanius, where he had found twelve dog pups (whence the Etruscan name ''Tus''-''Cana'', ''cana'' being similar to Latin ''canis'' for "dog"). Another legend attributes the foundation to one Tusco, son of Hercules and Araxes. Evidence of human presence in the area dates from the Neolithic age, but probably the city proper was founded in the 7th century BC when the acropolis on St. Peter's Hill was surrounded by a line of walls. Villages existed in the vicinity. In the following years its strategic position gave Tuscania a leading role in the Etruscan world. After the defeat of the coastal cities by the Greeks (4th century BC), Tuscania also became a maritime trade centre through the port of ''Regas'' (next to today's Montalto di Castro). There is no re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of New York And New Jersey
The Port of New York and New Jersey is the port district of the New York-Newark metropolitan area, encompassing the region within approximately a radius of the Statue of Liberty National Monument. It includes the system of navigable waterways in the New York–New Jersey Harbor Estuary, which runs along over of shoreline in the vicinity of New York City and northeastern New Jersey, and is considered one of the largest natural harbors in the world. Having long been the busiest port on the East Coast it became it the busiest port by maritime cargo volume in the United States in August 2022 and is a major economic engine for the region. The region's airports make the port the nation's top gateway for international flights and its busiest center for overall passenger and air freight flights. There are two foreign-trade zones (FTZ) within the port. Geography Port district Encompassing an area within an approximate radius of the Statue of Liberty National Monument, ...

Southampton
Southampton () is a port city in the ceremonial county of Hampshire in southern England. It is located approximately south-west of London and west of Portsmouth. The city forms part of the South Hampshire built-up area, which also covers Portsmouth and the towns of Havant, Waterlooville, Eastleigh, Fareham and Gosport. A major port, and close to the New Forest, it lies at the northernmost point of Southampton Water, at the confluence of the River Test and Itchen, with the River Hamble joining to the south. Southampton is classified as a Medium-Port City . Southampton was the departure point for the and home to 500 of the people who perished on board. The Spitfire was built in the city and Southampton has a strong association with the ''Mayflower'', being the departure point before the vessel was forced to return to Plymouth. In the past century, the city was one of Europe's main ports for ocean liners and more recently, Southampton is known as the home port of some of ...

Official Number
Official numbers are ship identifier numbers assigned to merchant ships by their flag state, country of registration. Each country developed its own official numbering system, some on a national and some on a port-by-port basis, and the formats have sometimes changed over time. As an internationally recognized ship identifier, national official numbers have largely been superseded by the IMO number, though flag states still use national systems, which also cover those vessels not subject to the IMO regulations. British official number Beginning in 1855, with the implementation of the Merchant Shipping Act 1854, all British seagoing vessels were assigned an official number to give each ship a unique identity, even after being renamed or changing the port of registry. U.S. official number After the passage of legislation in the United States Congress in 1866, all American ships were required to carve the official number on the main beam; the system was controlled by the Bureau of Sta ...

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post–World War I Recession
The post–World War I recession was an economic recession that hit much of the world in the aftermath of World War I. In many nations, especially in North America, economic growth continued and even accelerated during World War I as nations mobilized their economies to fight the war in Europe. After the war ended, the global economy began to decline. In the United States, 1918–1919 saw a modest economic retreat, but the second part of 1919 saw a mild recovery. A more severe recession hit the United States in 1920 and 1921, when the global economy fell very sharply. North America In North America, the recession immediately following World War I was extremely brief, lasting for only seven months from August 1918 (even before the war had actually ended) to March 1919. A second, much more severe recession, sometimes labeled a depression, began in January 1920. Several indices of economic activity suggest the recession was moderately severe.

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 ...

Gear Train
A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. Features of gears and gear trains include: * The gear ratio of the pitch circles of mating gears defines the speed ratio and the mechanical advantage of the gear set. * A planetary gear train provides high gear reduction in a compact package. * It is possible to design gear teeth for gears that are non-circular, yet still transmit torque smoothly. * The speed ratios of chain and belt drives are computed in the same way as gear ratios. See bicycle gearing. The transmission of rotation between contacting toothed wheels can be traced back to the Antikythera mechanism of Greece and the south-pointing chariot of China. Illustrations by the Renaissance scientist Georgius Agricola show gear trains with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
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 (ship), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...
