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 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 human ...

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. 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. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early 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 Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet i ...

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). The French t ...

Isambard Kingdom Brunel
Isambard Kingdom Brunel (; 9 April 1806 – 15 September 1859) was a British civil 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 propeller-driven 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 in the building of the first tunnel under a navigable river (the River Thames) and the development of the , the first ...

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 Thame ...

Globalization
Globalization, or globalisation (Commonwealth English; see spelling differences), is the process of interaction and integration among people, companies, and governments worldwide. The term ''globalization'' first appeared in the early 20th century (supplanting an earlier French term ''mondialization''), developed its current meaning some time 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 world. Its origins can be traced back to 18th and 19th centuries due to advances in transportation and communications technology. This increase in global interactions has caused a growth in international trade and the exchange of ideas, beliefs, and culture. Globalization is primarily an economic process of interaction and integration that is associated with social and cultural aspects. However, disputes and international diplomacy are also large parts of the history of globalizat ...

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 ...

Horseley Ironworks
The Horseley Ironworks (sometimes spelled Horsley) was a major ironworks in the Tipton area in the county of Staffordshire, now the West Midlands, England. History Founded by Aaron Manby, it is most famous for constructing the first iron steamer, '' The Aaron Manby'', in 1821.''Energy and Empire: A Biographical Study of Lord Kelvin'', Crosbie Smith, Matthew Norton Wise, 1989, Cambridge University Press () The boat was assembled at Rotherhithe. She was only the first of a number of steamboats built on the "knock-down" principle. The ironworks have also been responsible for the manufacture of numerous canal and railway bridges of the 19th century. The ironworks were built near the Toll End Communication Canal''Canal Companion – Birmingham Canal Navigations'', J. M.

Dover
Dover () is a town and major ferry port in Kent, South East England. It faces France across the Strait of Dover, the narrowest part of the English Channel at from Cap Gris Nez in France. It lies south-east of Canterbury and east of Maidstone. The town is the administrative centre of the Dover District and home of the Port of Dover. Archaeological finds have revealed that the area has always been a focus for peoples entering and leaving Great Britain, Britain. The name derives from the River Dour that flows through it. In recent times the town has undergone transformations with a high-speed rail link to London, new retail in town with St James' area opened in 2018, and a revamped promenade and beachfront. This followed in 2019, with a new 500m Pier to the west of the Harbour, and new Marina unveiled as part of a £330m investment in the area.

Steam Engine, Elevation Plan And Section Of A Steam-boat
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

Hellevoetsluis
Hellevoetsluis () is a small city and municipality in the western Netherlands. It is located in Voorne-Putten, South Holland. The municipality covers an area of of which is water and it includes the population centres Nieuw-Helvoet, Nieuwenhoorn, and Oude en Nieuwe Struiten, all former municipalities. Hellevoetsluis is located on the Haringvliet with the sea, beach, and dunes close by, on the extreme southern edge of the Rijnmond and Europoort areas, close to the broad Zeeland landscape. The name translates as "lock at the foot of the Helle". The Helle was a small local river that disappeared over time. History The area has been settled since before Roman times and was concentrated around a body of water called the "Helle", which was later Latinized by the Romans to "''Helinium''" and "''Helius''". The name Hel(le) Voet, ''Helius' foot'' or "(land at) the lowest point of Helius", appears in documents from the 13th century and later, such as in 1395, when the Nieuw-Helvoet Polder ...
