Steamships
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 19th century; 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 incorrectly 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 u ...

Steamboat
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. The term ''steamboat'' is used to refer to small steam-powered vessels working on lakes, rivers, and in short-sea shipping. The development of the steamboat led to the larger steamship, which is a seaworthy and often ocean-going ship. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. Background Limitations of the Newcomen steam engine The first steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The heavy weight of the Newcomen engine required a structurally strong boat, and the reciprocating motion of the engine beam required a compli ...

Steam-powered Vessel
Steam-powered vessels include steamboats and steamships. Smaller steamboats were developed first. They were replaced by larger steamships which were often ocean-going. Steamships required a change in propulsion technology from sail to paddlewheel to screw to steam turbines. The latter innovation changed the design of vessels to one that could move faster through the water. Engine propulsion changed to steam turbine in the early 20th century. In the latter part of the 20th century, these, in turn, were replaced by gas turbines. ''Steamship'' generally refers to a larger steam-powered ship, usually ocean-going, capable of carrying a (ship's) boat. The engine room, to the right, is a concept drawing during the construction of the ship. The term steam wheeler is archaic and rarely used. In England, "steam packet", after its sailing predecessor, was the usual term; even "steam barge" could be used (Steam tonnage in Lloyd's Register exceeded sailing ships tonnage by 1865).

Aaron Manby
''Aaron Manby'' was a landmark vessel in the science of shipbuilding as the first iron steamship to go to sea. She was built by Aaron Manby (1776–1850) at the Horseley Ironworks. She made the voyage to Paris in June 1822 under Captain (later Admiral) Charles Napier, with Aaron's son Charles on board as engineer. ''Aaron Manby'' was then used by the ''Compagnie des bateaux a vapeur en fer'' to operate its service between Paris and Le Havre. Vessel history Launched in 1821, ''Aaron Manby'' was the first steamship to be built of iron. She was the brainchild of the eccentric but far-seeing naval officer Captain (later Admiral) Charles Napier, who had conceived the idea of a fleet of steamships for service on the River Seine. The ship was named after the master of the Horseley Ironworks, Tipton, Staffordshire, where she was pre-fabricated to a design jointly formulated by Captain Napier, Aaron Manby and his son Charles. She was then shipped in pieces to Rotherhithe on the T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isambard Kingdom Brunel
Isambard Kingdom Brunel ( ; 9 April 1806 – 15 September 1859) was an English civil engineer and mechanical engineer who is considered "one of the most ingenious and prolific figures in engineering history", "one of the 19th-century engineering giants", and "one of the greatest figures of the Industrial Revolution, hochanged the face of the English landscape with his groundbreaking designs and ingenious constructions". Brunel built dockyards, the Great Western Railway (GWR), a series of steamships including the first purpose-built transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering. Though Brunel's projects were not always successful, they often contained innovative solutions to long-standing engineering problems. During his career, Brunel achieved many engineering firsts, including assisting his father in the building of the first tunnel under a navigable river (the River Thames) and ...

Propeller
A propeller (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 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 stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the propeller, screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Globalization
Globalization is the process of increasing interdependence and integration among the economies, markets, societies, and cultures of different countries worldwide. This is made possible by the reduction of barriers to international trade, the liberalization of capital movements, the development of transportation, and the advancement of information and communication technologies. The term ''globalization'' first appeared in the early 20th century (supplanting an earlier French term ''mondialisation''). It developed its current meaning sometime in the second half of the 20th century, and came into popular use in the 1990s to describe the unprecedented international connectivity of the Post–Cold War era, post–Cold War world. The origins of globalization can be traced back to the 18th and 19th centuries, driven by advances in transportation and communication technologies. These developments increased global interactions, fostering the growth of international trade and the exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seaworthy
Seakeeping ability or seaworthiness is a measure of how well-suited a watercraft is to conditions when underway. A ship or boat which has good seakeeping ability is said to be very seaworthy and is able to operate effectively even in high sea states. Measure In 1976, St. Denis suggested four principal terms needed to describe a seakeeping performance. These are: *Mission: what the ship is intended to accomplish. The role of the ship while at sea. *Environment: the conditions under which the ship is operating. This can be described as sea state, wind speed, geographic region or some combination thereof. *Ship responses: the response of the ship to the environmental conditions. The responses are a function of the environment and the vessel characteristics. *Seakeeping performance criteria: the established limits for the ship's responses. These are based on the ship motions and the accelerations experienced, and include comfort criteria such as noise, vibration and sea sickness, p ...

Surinam (Dutch Colony)
Surinam (), also unofficially known as Dutch colonisation of the Guianas, Dutch Guiana, was a Dutch plantation economy, plantation colony in the Guianas and the predecessor polity of modern country of Suriname. It was bordered by the fellow Dutch colony of Berbice to the west, and the French colony of French Guiana, Cayenne to the east. It later bordered British Guiana (modern-day Guyana) from 1831 to 1966. History The colonization of Suriname Surinam was a Dutch colony from 26 February 1667, when Dutch forces captured Francis Willoughby, 5th Baron Willoughby of Parham, Francis Willoughby's England, English colony during the Second Anglo-Dutch War, until 15 December 1954, when Surinam became a Suriname (Kingdom of the Netherlands), constituent country of the Kingdom of the Netherlands. The status quo of Dutch sovereignty over Surinam, and English sovereignty over New Netherland, which it had conquered in 1664, was kept in the Treaty of Breda (1667), Treaty of Breda of 31 ...

Paramaribo
Paramaribo ( , , ) is the capital city, capital and largest city of Suriname, located on the banks of the Suriname River in the Paramaribo District. Paramaribo has a population of roughly 241,000 people (2012 census), almost half of Suriname's population. The historic inner city of Paramaribo has been a UNESCO World Heritage Site since 2002. Name The city is named for the Paramaribo tribe living at the mouth of the Suriname River; the name is from Tupi–Guarani languages, Tupi–Guarani ''para'' "large river" + ''maribo'' "inhabitants". History The name Paramaribo is probably a corruption of the name of a native village, spelled Parmurbo in the earliest Dutch sources. This was the location of the first Dutch settlement, a trading post established by Nicolaes Baliestel and Dirck Claeszoon van Sanen in 1613. English and French traders also tried to establish settlements in Suriname, including a French post established in 1644 near present-day Paramaribo. All earlier settle ...
