190-458: A barge -hauler, Charlotte Dundas , for the Forth and Clyde Canal Company . It successfully hauled two 70-ton barges almost 20 mi (32 km) in 6 hours against a strong headwind on test in 1802. Enthusiasm was high, but some directors of the company were concerned about the banks of the canal being damaged by the wash from a powered vessel, and no more were ordered. While Charlotte Dundas
285-457: A lifeboat lowered on the starboard side to check the extent of the damage but it never regained the steamer. Within twenty minutes, Lady Elgin broke apart, and all but the bow section rapidly sank. The night was lit up at intervals by flashes of lightning showing the scattered wreckage. The life preservers , 2 in (5.1 cm) hardwood planks, 5 ft (1.5 m) long and 18 in (46 cm) wide, were never used. Two boats with
380-610: A boat with a pair of paddlewheels at each end turned by men operating compound cranks. The concept was improved by the Italian Roberto Valturio in 1463, who devised a boat with five sets, where the parallel cranks are all joined to a single power source by one connecting rod, an idea adopted by his compatriot Francesco di Giorgio . In 1539, Spanish engineer Blasco de Garay received the support of Charles V to build ships equipped with manually-powered side paddle wheels. From 1539 to 1543, Garay built and launched five ships,

Three hundred men and women spent the day of September 7 listening to political speeches followed by an evening of entertainment by a German brass band on board Lady Elgin . On the return trip that night, the brightly lit Lady Elgin was steaming through Lake Michigan against gale force winds when she
570-456: A centre for the transshipment of sea cargo to inland destinations. A smart port uses technologies, including the Internet of Things (IoT) and artificial intelligence (AI) to be more efficient at handling goods. Smart ports usually deploy cloud-based software as part of the process of greater automation to help generate the operating flow that helps the port work smoothly. At present, most of

One of the first functioning steamships , Palmipède , which was also the first paddle steamer, was built in France in 1774 by Marquis Claude de Jouffroy and his colleagues. The 13 m (42 ft 8 in) steamer with rotating paddles sailed on the Doubs River in June and July 1776. In 1783,
855-876: A fishing port to be uneconomical. A marina is a port for recreational boating. A warm-water port (also known as an ice-free port) is one where the water does not freeze in winter. This is mainly used in the context of countries with mostly cold winters where parts of the coastline freezes over every winter. Because they are available year-round, warm-water ports can be of great geopolitical or economic interest . Such settlements as Narvik in Norway, Dalian in China, Murmansk , Novorossiysk , Petropavlovsk-Kamchatsky and Vostochny Port in Russia, Odesa in Ukraine, Kushiro in Japan and Valdez at

1235-617: A monument dedicated to the Lady Elgin disaster and the many lost in the tragedy who are buried there. Songwriter Henry Clay Work penned the memorial song "Lost on the Lady Elgin" in 1861. For many years in central Canada this song was sung at family gatherings and social occasions. In 2009, the Milwaukee Irish Heritage and Cultural Center launched a $ 200,000 fundraising campaign for a mammoth, two-story bronze memorial statue for
1330-551: A new paddle steamer by de Jouffroy, Pyroscaphe , successfully steamed up the river Saône for 15 minutes before the engine failed. Bureaucracy and the French Revolution thwarted further progress by de Jouffroy. The next successful attempt at a paddle-driven steam ship was by Scottish engineer William Symington , who suggested steam power to Patrick Miller of Dalswinton . Experimental boats built in 1788 and 1789 worked successfully on Lochmaben Loch. In 1802, Symington built

The ancient Chinese mathematician and astronomer Zu Chongzhi (429–500) had a paddle-wheel ship built on the Xinting River (south of Nanjing ) known as
1520-711: A port or nearby. Modern ports will have specialised cargo -handling equipment, such as gantry cranes , reach stackers and forklift trucks . Ports usually have specialised functions: some tend to cater mainly for passenger ferries and cruise ships ; some specialise in container traffic or general cargo; and some ports play an important military role for their nation's navy. Some third world countries and small islands such as Ascension and St Helena still have limited port facilities, so that ships must anchor off while their cargo and passengers are taken ashore by barge or launch (respectively). In modern times, ports survive or decline, depending on current economic trends. In
1615-529: A principal cause of the collision was the lack of a $ 15 lantern on the Augusta. Steamboat historian Peter Charlebois noted that, after the investigation, Captain Malott and Lady Elgin's crew and owners were absolved of any blame. He reported: The judgement was based on a law that not only gave sail the right of way over steam, but did not require sailing vessels to carry running lights. Apparently Augusta had sighted
1710-584: A reconnaissance survey of the wreck site in 1992. Cave dive sites: Paddle steamer 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 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. The paddle wheel
1805-462: A rod and lever. The geometry is designed such that the paddles are kept almost vertical for the short duration that they are in the water. The use of a paddle wheel in navigation appears for the first time in the mechanical treatise of the Roman engineer Vitruvius ( De architectura , X 9.5–7), where he describes multigeared paddle wheels working as a ship odometer . The first mention of paddle wheels as
1900-424: A ship on its sailing itinerary. At these ports, cargo ships may take on supplies or fuel, as well as unloading and loading cargo while cruise liners have passengers get on or off ship. A fishing port is a port or harbor for landing and distributing fish. It may be a recreational facility, but it is usually commercial. A fishing port is the only port that depends on an ocean product, and depletion of fish may cause
1995-506: A ship to sail from the ocean inland to the port to load or unload its cargo. An example of this is the St. Lawrence Seaway which allows ships to travel from the Atlantic Ocean several thousand kilometers inland to Great Lakes ports like Toronto , Duluth-Superior , and Chicago . The term inland port is also used for dry ports . A seaport is a port located on the shore of a sea or ocean. It

In the 12th century, the Song government used paddle-wheel ships en masse to defeat opposing armies of pirates armed with their own paddle-wheel ships. At the Battle of Caishi in 1161, paddle-wheelers were also used with great success against
2185-419: A simple paddle wheel, where the paddles are fixed around the periphery, power is lost due to churning of the water as the paddles enter and leave the water surface. Ideally, the paddles should remain vertical while under water. This ideal can be approximated by use of levers and linkages connected to a fixed eccentric. The eccentric is fixed slightly forward of the main wheel centre. It is coupled to each paddle by

In mainland Europe, it is normal for ports to be publicly owned, so that, for instance, the ports of Rotterdam and Amsterdam are owned partly by the state and partly by
2375-541: A steam-powered desalinator created by Garay for a steam boiler. In 1705, Papin constructed a ship powered by hand-cranked paddles. An apocryphal story originating in 1851 by Louis Figuire held that this ship was steam-powered rather than hand-powered and that it was therefore the first steam-powered vehicle of any kind. The myth was refuted as early as 1880 by Ernst Gerland [ de ] , though still it finds credulous expression in some contemporary scholarly work. In 1787, Patrick Miller of Dalswinton invented
2470-641: A third of the world's shipping containers , half of the world's annual supply of crude oil , and is the world's busiest transshipment port . Europe's busiest container port and biggest port by cargo tonnage by far is the Port of Rotterdam , in the Netherlands. It is followed by the Belgian Port of Antwerp or the German Port of Hamburg , depending on which metric is used. In turn, the Spanish Port of Valencia

The drummer of the German band, Charles Beverung, saved himself by using his large bass drum as a life preserver. Survivors reported the heroic efforts of Captain Wilson to save about 300 persons collected on a raft. When day broke, between 350 and 400 passengers and crew were drifting in stormy waters, holding on to anything they could, many only to be pulled under by breakers near shore. Students from Northwestern University and Garrett Biblical Institute were watching
2660-623: A wide environmental impact on local ecologies and waterways, most importantly water quality, which can be caused by dredging, spills and other pollution . Ports are heavily affected by changing environmental factors caused by climate change as most port infrastructure is extremely vulnerable to sea level rise and coastal flooding . Internationally, global ports are beginning to identify ways to improve coastal management practices and integrate climate change adaptation practices into their construction. Wherever ancient civilisations engaged in maritime trade, they tended to develop sea ports. One of

Bulk cargo ports may handle one particular type of cargo or numerous cargoes, such as grains, liquid fuels, liquid chemicals, wood, automobiles, etc. Such ports are known as
2945-688: Is often lower because of both direct and indirect pollution from the shipping, and other challenges caused by the port's community, such as trash washing into the ocean. Sewage from ships, and leaks of oil and chemicals from shipping vessels can contaminate local water, and cause other effects like nutrient pollution in the water. Ports and their infrastructure are very vulnerable to climate change and sea level rise, because many of them are in low-lying areas designed for status quo water levels. Variable weather, coastal erosion, and sea level rise all put pressure on existing infrastructure, resulting in subsidence , coastal flooding and other direct pressures on

Ports are often on estuaries, where the water may be shallow and may need regular dredging . Deep water ports such as Milford Haven are less common, but can handle larger ships with a greater draft, such as super tankers , Post-Panamax vessels and large container ships . Other businesses such as regional distribution centres , warehouses and freight-forwarders, canneries and other processing facilities find it advantageous to be located within

In the Second World War , some thirty pleasure paddle steamers were again requisitioned; an added advantage was that their wooden hulls did not activate the new magnetic mines. The paddle ships formed six minesweeping flotillas , based at ports around the British coast. Other paddle steamers were converted to anti-aircraft ships. More than twenty paddle steamers were used as emergency troop transports during

At the siege of Liyang in 573, the admiral Huang Faqiu employed foot-treadle powered paddle-wheel boats. A successful paddle-wheel warship design was made in China by Prince Li Gao in 784 AD, during an imperial examination of
4370-468: The "bulk" or "break bulk ports". Ports that handle containerized cargo are known as container ports . Most cargo ports handle all sorts of cargo, but some ports are very specific as to what cargo they handle. Additionally, individual cargo ports may be divided into different operating terminals which handle the different types of cargoes, and may be operated by different companies, also known as terminal operators, or stevedores . A cruise home port
4465-423: The 1820s, paddle steamers were used to take tourists from the rapidly expanding industrial cities on river cruises, or to the newly established seaside resorts , where pleasure piers were built to allow passengers to disembark regardless of the state of the tide. Later, these paddle steamers were fitted with luxurious saloons in an effort to compete with the facilities available on the railways. Notable examples are
4560-614: The 1980s, the steam engines were replaced with diesel ones, and the wooden paddles were replaced with iron ones. Hydraulic steering was introduced in the 1990s, followed by electro-hydraulic systems in 2020. Modern equipment such as radar and GPS was also installed. However, PS Gazi , PS Teal , and PS Kiwi were decommissioned in the late '90s after catching fire while docked for repairs. Until 2022, four paddle steamers—PS Ostrich (built in Scotland in 1929), PS Mahsud (1928), PS Lepcha (1938), and PS Tern (1950)—were operated by

Great Western , however, was actually built for the transatlantic trade, and so had sufficient coal for the passage; Sirius had to burn furniture and other items after running out of coal. Great Western ' s more successful crossing began the regular sailing of powered vessels across
4750-629: The Atlantic. Beaver was the first coastal steamship to operate in the Pacific Northwest of North America. Paddle steamers helped open Japan to the Western World in the mid-19th century. The largest paddle-steamer ever built was Brunel's Great Eastern , but it also had screw propulsion and sail rigging. It was 692 ft (211 m) long and weighed 32,000 tons, its paddlewheels being 56 ft (17 m) in diameter. In oceangoing service, paddle steamers became much less useful after

Even in more recent times, ports sometimes fall out of use. Rye, East Sussex , was an important English port in the Middle Ages, but the coastline changed and it is now 2 miles (3.2 km) from the sea, while the ports of Ravenspurn and Dunwich have been lost to coastal erosion . Whereas early ports tended to be just simple harbours, modern ports tend to be multimodal distribution hubs , with transport links using sea, river, canal, road, rail and air routes. Successful ports are located to optimize access to an active hinterland , such as

6745-444: The most famous being the modified Portuguese carrack La Trinidad , which surpassed a nearby galley in speed and maneuverability on June 17, 1543, in the harbor of Barcelona . The project, however, was discontinued. 19th century writer Tomás González claimed to have found proof that at least some of these vessels were steam-powered, but this theory was discredited by the Spanish authorities. It has been proposed that González mistook
6840-660: The narrower, winding rivers of the Murray–Darling system in Australia, where a number still operate. European sidewheelers, such as PS Waverley , connect the wheels with solid drive shafts that limit maneuverability and give the craft a wide turning radius. Some were built with paddle clutches that disengage one or both paddles so they can turn independently. However, wisdom gained from early experience with sidewheelers deemed that they be operated with clutches out, or as solid-shaft vessels. Crews noticed that as ships approached
6935-422: The passenger steamer twenty minutes before the collision but in the rain had misjudged the distance between them. Four years after the disaster, in 1864, a new ruling was made requiring sailing vessels to carry running lights. Since there were still nearly 1,900 ships under sail by 1870 the regulations were long overdue. The wreck of Lady Elgin was discovered in 1989 off Highwood , Illinois by Harry Zych. Zych
7030-615: The port. There are several initiatives to decrease negative environmental impacts of ports. The World Port Sustainability Program points to all of the Sustainable Development Goals as potential ways of addressing port sustainability. These include SIMPYC , the World Ports Climate Initiative , the African Green Port Initiative , EcoPorts and Green Marine . The port of Shanghai
7125-486: The provinces by the Tang dynasty (618–907) emperor. The Chinese Song dynasty (960–1279) issued the construction of many paddle-wheel ships for its standing navy , and according to the British biochemist, historian, and sinologist Joseph Needham : "...between 1132 and 1183 (AD) a great number of treadmill-operated paddle-wheel craft, large and small, were built, including sternwheelers and ships with as many as 11 paddle-wheels
7220-436: The sea via rivers or canals . Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide
7315-588: The shore on the morning of September 8, looking for survivors. One of the students, Edward Spencer, is credited with rescuing 17 passengers over the course of six hours. He sustained injuries during his rescue efforts that left him an invalid for the rest of his life. A plaque in his honor was first placed in the Northwestern University Gymnasium, and is now housed in the Northwestern University Library. About 300 people died in
7410-431: The sinking, including Captain Wilson, who was lost trying to save two women when he was caught by the surf and forced into the rocks. Most were from Milwaukee with the majority of those from the Irish communities, including nearly all of Milwaukee's Irish Union Guard. So many Irish-American political operatives died that day that the disaster has been credited with transferring the balance of political power in Milwaukee "from
7505-721: The southern rivers. In 1958, Pakistan River Steamers inherited the fleet, some of which were built at the private Garden Rich Dockyard in Kolkata . After the liberation of Bangladesh , there were around 13 paddle steamers in 1972, nicknamed “the Rockets” for their speed, operated by the newly founded Bangladesh Inland Water Transport Corporation (BIWTC). These included PS Sandra , PS Lali , PS Mohammed , PS Gazi , PS Kiwi , PS Ostrich , PS Mahsud , PS Lepcha , and PS Tern . The steamers served destinations such as Chandpur , Barisal , Khulna , Morrelganj , and Kolkata , from Dhaka . In
7600-522: The start of the First World War , the Royal Navy requisitioned more than fifty pleasure paddle steamers for use as auxiliary minesweepers . The large spaces on their decks intended for promenading passengers proved to be ideal for handling the minesweeping booms and cables, and the paddles allowed them to operate in coastal shallows and estuaries. These were so successful that a new class of paddle ships,
7695-525: The terminus of the Alaska Pipeline owe their very existence to being ice-free ports. The Baltic Sea and similar areas have ports available year-round beginning in the 20th century thanks to icebreakers , but earlier access problems prompted Russia to expand its territory to the Black Sea . A dry port is an inland intermodal terminal directly connected by road or rail to a seaport and operating as
7790-439: The type was by far the dominant mode of marine steam propulsion, both for steamships and steamboats, until the increasing adoption of screw propulsion from the 1850s. Though the side wheels and enclosing sponsons make them wider than sternwheelers, they may be more maneuverable, since they can sometimes move the paddles at different speeds, and even in opposite directions. This extra maneuverability makes side-wheelers popular on
7885-414: The water column, and can stir up pollutants captured in the sediments. Invasive species are often spread by the bilge water and species attached to the hulls of ships. It is estimated that there are over 7000 invasive species transported in bilge water around the world on a daily basis Invasive species can have direct or indirect interactions with native sea life. Direct interaction such as predation,
7980-421: The water to increase efficiency. The upper part of a paddle wheel is normally enclosed in a paddlebox to minimise splashing. The three types of paddle wheel steamer are sidewheeler, with one paddlewheel amidships on each side; sternwheeler, with a single paddlewheel at the stern ; and (rarely) inboard, with the paddlewheel mounted in a recess amidships. The earliest steam vessel s were sidewheelers, and
8075-415: The waterline. Concerned that she was damaged and believing Lady Elgin had got safely away, Augusta made for Chicago. Aboard Lady Elgin , Captain Wilson ordered that cattle and cargo be thrown overboard to lighten the load and raise the gaping hole in Lady Elgin's port side above water level while the steward was down in the coal bunker trying to stop the leak with mattresses. Captain Wilson ordered
8170-516: The wooden-hulled sidewheeler was one of the most elegantly appointed passenger ships plying the Great Lakes . Rated a first-class steamer , she was a favorite with the traveling public. Early in her career she ran between Buffalo and Chicago, then later between Chicago and Collingwood, Ontario . For many of her later seasons, she plied the route between Chicago and other Lake Michigan ports and Lake Superior . During Lady Elgin ' s career she
8265-527: The world's oldest known artificial harbors is at Wadi al-Jarf on the Red Sea . Along with the finding of harbor structures, ancient anchors have also been found. Other ancient ports include Guangzhou during Qin dynasty China and Canopus , the principal Egyptian port for Greek trade before the foundation of Alexandria . In ancient Greece, Athens' port of Piraeus was the base for the Athenian fleet which played
8360-766: The world's ports have somewhat embedded technology, if not for full leadership. However, thanks to global government initiatives and exponential growth in maritime trade, the number of intelligent ports has gradually increased. A report by business intelligence provider Visiongain assessed that Smart Ports Market spending would reach $ 1.5 bn in 2019. Ports and their operation are often a cause of environmental issues, such as sediment contamination and spills from ships and are susceptible to larger environmental issues, such as human caused climate change and its effects. Every year 100 million cubic metres of marine sediment are dredged to improve waterways around ports. Dredging, in its practice, disturbs local ecosystems, brings sediments into
8455-474: Was awarded ownership in 1999 after a protracted legal battle. The wreck, consisting of four main debris fields lying in 50 and 60 feet (15 and 18 m) of water, has been stripped of artifacts through the years. Divers must obtain permission from Zych and Lady Elgin Foundation, and are expected to observe the preservation laws governing historic sites. The Underwater Archaeological Society of Chicago undertook
8550-526: Was involved in numerous accidents. She sank and was repaired in 1854 after striking a rock at Manitowoc, Wisconsin . In 1855, she was towed to Chicago after an accident to her machinery. In 1857, she was damaged by fire. In June 1858, she struck a reef at Copper Harbor, Michigan . In August 1858, she was stranded on Au Sable Point Reef in Lake Superior. In October 1859, she was towed to Marquette, Michigan after breaking her crossbeam . In November 1859, she
8645-465: Was purely for the purpose of moving a river-boat to a new market, but paddle-steamers began regular short coastal trips soon after. In 1816 Pierre Andriel, a French businessman, bought in London the 15 hp (11 kW) paddle steamer Margery (later renamed Elise ) and made an eventful London- Le Havre -Paris crossing, encountering heavy weather on the way. He later operated his ship as a river packet on
8740-406: Was rammed by the schooner Augusta of Oswego . Augusta was sailing using only a single white light, mounted on a five-foot Samson on the bow, and did not attempt, or was unable, to turn to avoid the collision in the gale. On the morning of the collision (September 8) at 2:30 am, Augusta rammed the port side of Lady Elgin , damaging her own bowsprit and headgear, while holing the latter ship below
8835-636: Was steamed from Newcastle to San Francisco. As the voyage was intended to be completed under power, the tug was rigged as steam propelled with a sail auxiliary. The transatlantic stage of the voyage was completed exactly 150 years after the voyage of Savannah . As of 2022, the PS Waverley is the last seagoing passenger-carrying paddle steamer in the world. Beginning in the 1820s, the British Royal Navy began building paddle-driven steam frigates and steam sloops . By 1850 these had become obsolete due to
8930-507: Was the first commercial paddle steamer and steamboat , the first commercial success was possibly Robert Fulton 's Clermont in New York, which went into commercial service in 1807 between New York City and Albany . Many other paddle-equipped river boats followed all around the world; the first in Europe being PS Comet designed by Henry Bell which started a scheduled passenger service on
9025-558: Was towed again when her crank pin broke near Point Iroquois , Michigan. Her final blow came in 1860 when she was rammed by the wooden schooner Augusta ten miles from shore. In 1899, Great Lakes historian J.B. Mansfield called Lady Elgin ' s sinking "one of the greatest marine horrors on record". On the night of September 6, 1860 Lady Elgin left Milwaukee , Wisconsin , from the Dooley, Martin, Dousman, and Company Dock, for Chicago, carrying members of Milwaukee 's Union Guard to hear
