Maritime transport (or ocean transport ) or more generally waterborne transport , is the transport of people ( passengers ) or goods ( cargo ) via waterways . Freight transport by sea has been widely used throughout recorded history . The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises . Transport by water is cheaper than transport by air or ground, but significantly slower for longer distances. Maritime transport accounts for roughly 80% of international trade , according to UNCTAD in 2020.

50-529: Maritime transport can be realized over any distance by boat, ship, sailboat or barge , over oceans and lakes, through canals or along rivers. Shipping may be for commerce , recreation , or military purposes. While extensive inland shipping is less critical today, the major waterways of the world including many canals are still very important and are integral parts of worldwide economies . Particularly, especially any material can be moved by water; however, water transport becomes impractical when material delivery

100-409: A flat-bottomed vessel which does not have its own means of mechanical propulsion. Original use was on inland waterways, while modern use is on both inland and marine water environments. The first modern barges were pulled by tugs , but on inland waterways, most are pushed by pusher boats , or other vessels. The term barge has a rich history, and therefore there are many types of barges. "Barge"

150-407: A British canal boat of traditional long, narrow design, steered with a tiller; spec. one not exceeding 7 feet (approx. 2.1 metres) in width or 72 feet (approx. 21.9 metres) in length The narrowboats were initially also known as barges, and the new canals were constructed with an adjacent towpath along which draft horses walked, towing the barges. These types of canal craft are so specific that on

200-519: A United Nations agency, and the Nautical Institute are seeking improved international standards for mariners. Satellite phones have improved communication and efficiency aboard sea-faring ships. This technology has contributed to crew welfare, although both equipment and fees are expensive. Ocean voyages are steeped in routine. Maritime tradition dictates that each day be divided into six four-hour periods. Three groups of watch keepers from

250-481: A barge has given rise to the saying "I wouldn't touch that [subject/thing] with a barge pole." In the United States a barge was not a sailing vessel by the end of the 19th century. Indeed, barges were often created by cutting down ( razeeing ) sailing vessels. In New York this was an accepted meaning of the term barge. The somewhat smaller scow was built as such, but the scow also had its sailing counterpart

300-402: A cargo engineer works with the deck department during cargo operations, as well as being a watchkeeping engineer. A common engine crew for a ship includes: Many American ships also carry a motorman . Other possible positions include machinist , electrician , refrigeration engineer, and tankerman. Engine cadets are engineer trainees who are completing sea time necessary before they can obtain

350-447: A dumb barge. In Europe, a Dumb barge is: An inland waterway transport freight vessel designed to be towed which does not have its own means of mechanical propulsion . In America, a barge is generally pushed. Barges are used today for transporting low-value bulk items, as the cost of hauling goods that way is very low and for larger project cargo, such as offshore wind turbine blades. Barges are also used for very heavy or bulky items;

400-553: A few decades, the term dumb barge evolved, and came to mean: 'a vessel propelled by oars only'. By the 1890s Dumb barge was still used only on the Thames. By 1880 barges on British rivers and canals were often towed by steam tugboats. On the Thames, many dumb barges still relied on their poles, oars and the tide. Others dumb barges made use of about 50 tugboats to tow them to their destinations. While many coal barges were towed, many dumb barges that handled single parcels were not. On

450-695: A mariner's off-duty time is largely a solitary affair, pursuing hobbies, reading, writing letters, and sleeping. On modern ocean-going vessels, typically registered with a flag of convenience , life has changed immensely in the last 20 years. Most large vessels include a gym and often a swimming pool for use by the crew. Since the Exxon Valdez incident , the focus of leisure time activity has shifted from having officer and crew bars, to simply having lounge-style areas where officers or crew can sit to watch movies. With many companies now providing TVs and DVD players in cabins, and enforcing strict smoking policies, it

500-566: A ship, including Junior Assistant Purser , Senior Assistant Purser , Purser , Chief Purser , Medical Doctor , Professional Nurse , Marine Physician Assistant , and hospital corpsman , are considered administrative positions and are therefore regulated by Certificates of Registry issued by the United States Coast Guard . Pilots are also merchant marine officers and are licensed by the Coast Guard. Formerly, there

550-464: A strategy referred to as " slow steaming ". A ship's complement can be divided into four categories: Officer positions in the deck department include but not limited to the Master and his Chief , Second , and Third officers. The official classifications for unlicensed members of the deck department are Able Seaman and Ordinary Seaman . A common deck crew for a ship includes: A deck cadet

600-493: A time, followed by protracted shore leave. However, some seamen secure jobs on ships they like and stay aboard for years. The quick turnaround of many modern ships, spending only a few hours in port, limits a seafarer's free-time ashore. Moreover, some foreign seamen entering U.S. ports from a watch list of 25 countries face restrictions on shore leave due to maritime security concerns. However, shore leave restrictions while in U.S. ports impact American seamen as well. For example,

650-454: A typical American barge measures 195 by 35 feet (59.4 m × 10.7 m), and can carry up to about 1,500 short tons (1,400 t) of cargo. The most common European barges measure 251 by 37 feet (76.5 m × 11.4 m) and can carry up to about 2,450 tonnes (2,700 short tons). As an example, on June 26, 2006, in the US a 565-short-ton (513 t) catalytic cracking unit reactor

700-499: A watchkeeping license. A typical steward's department for a cargo ship would be composed of a Chief Steward , a chief cook , and a Steward's Assistant . All three positions are typically filled by unlicensed personnel. The chief steward directs, instructs, and assigns personnel performing such functions as preparing and serving meals; cleaning and maintaining officers' quarters and steward department areas; and receiving, issuing, and inventorying stores. On large passenger vessels ,

750-655: Is time-critical such as various types of perishable produce . Still, water transport is highly cost effective with regular schedulable cargoes, such as trans-oceanic shipping of consumer products – and especially for heavy loads or bulk cargos , such as coal , coke , ores , or grains . Arguably, the Industrial Revolution had its first impacts where cheap water transport by canal, navigations, or shipping by all types of watercraft on natural waterways supported cost-effective bulk transport . Containerization revolutionized maritime transport starting in

800-422: Is a person who is carrying out mandatory sea time to achieve their officer of the watch certificate. Their time on board is spent learning the operations and tasks of everyday life on a merchant vessel. A ship's engine department consists of the members of a ship's crew that operate and maintain the propulsion and other systems on board the vessel. Engine staff also deal with the "Hotel" facilities on board, notably

850-509: Is attested from 1300, from Old French barge , from Vulgar Latin barga . The word originally could refer to any small boat; the modern meaning arose around 1480. Bark "small ship" is attested from 1420, from Old French barque , from Vulgar Latin barca (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from

900-406: Is not surprising that the bar is now a much quieter place on most ships. In some instances games consoles are provided for the officers and crew. The officers enjoy a much higher standard of living on board ocean-going vessels. Crews are generally poorly paid, poorly qualified and have to complete contracts of approximately 9 months before returning home on leave. They often come from countries where

950-597: Is the Bibby Stockholm . List of busiest ports in Europe The table below lists 20 of the busiest ports in Europe ; Rotterdam currently ranks first here, and eleventh in the world by cargo tonnage . For ferries, transport vehicles like heavy trucks are included using their full weight, while passenger cars are not counted as cargo. The table below lists 20 of the busiest container ports in Europe with

1000-554: The International Organization of Masters, Mates & Pilots notes a trend of U.S. shipping terminal operators restricting seamen from traveling from the ship to the terminal gate. Furthermore, in cases where transit is allowed, special "security fees" are at times assessed. Such restrictions on shore leave, coupled with reduced time in port, translate into longer periods at sea. Mariners report that extended periods at sea living and working with shipmates, who for

1050-475: The Latin barica , from Greek baris "Egyptian boat", from Coptic bari "small boat", hieroglyphic Egyptian and similar ba-y-r for "basket-shaped boat". By extension, the term "embark" literally means to board the kind of boat called a "barque". In Great Britain a merchant barge was originally a flat bottomed merchant vessel for use on navigable rivers. Most of these barges had sails. For traffic on

1100-520: The River Severn the barge was described thus: "The lesser sort are called barges and frigates, being from forty to sixty feet in length, having a single mast and square sail, and carrying from twenty to forty tons burthen." The larger vessels were called trows. On the River Irwell there was reference to barges passing below Barton Aqueduct with their mast and sails standing. Early barges on

1150-557: The Steward's Assistant , the chief cook , and other Steward's Department crewmembers. In the United States Merchant Marine , a chief steward must have a Merchant Mariner's Document issued by the United States Coast Guard . Because of international law , conventions, and agreements , all chief cooks who sail internationally are similarly documented by their respective countries. Staff officer positions on

1200-625: The Thames were called west country barges. In the United Kingdom the word barge had many meanings by the 1890s, and these varied locally. On the Mersey a barge was called a 'Flat', on the Thames a Lighter or barge, and on the Humber a 'Keel'. A Lighter had neither mast nor rigging. A keel did have a single mast with sails. Barge and lighter were used indiscriminately. A local distinction

1250-500: The narrowboat , which usually had a beam a couple of inches less to allow for clearance e.g. 6 feet 10 inches (2.08 m) . It was soon realized that the narrow locks were too limiting, and later locks were therefore doubled in width to 14 feet (4.3 m). This led to the development of the widebeam canal boat. The narrowboat (one word) definition in the Oxford English Dictionary is: Narrowboat:

1300-436: The sewage , lighting, air conditioning and water systems. They deal with bulk fuel transfers, and require training in firefighting and first aid , as well as in dealing with the ship's boats and other nautical tasks- especially with cargo loading/discharging gear and safety systems, though the specific cargo discharge function remains the responsibility of deck officers and deck workers. On LPG and LNG tankers , however,

1350-431: The 1970s. "General cargo" includes goods packaged in boxes, cases, pallets, and barrels. When a cargo is carried in more than one mode, it is intermodal or co-modal . A nation's shipping fleet (variously called merchant navy , merchant marine, or merchant fleet) consists of the ships operated by civilian crews to transport passengers or cargo from one place to another. Merchant shipping also includes water transport over

1400-696: The 2005 CIA World Factbook , the total number of merchant ships of at least 1,000 gross register tons in the world was 30,936. In 2010, it was 38,988, an increase of 26%, across many countries . As of December 2018, a quarter of all merchant mariners were born in the Philippines . A ship may also be categorized as to how it is operated. Ships and other watercraft are used for maritime transport. Types can be distinguished by propulsion , size or cargo type. Recreational or educational craft still use wind power, while some smaller craft use internal combustion engines to drive one or more propellers , or in

1450-717: The 4 month mark for officers, with generous leave. Most ocean-going vessels now operate an unmanned engine room system allowing engineers to work days only. The engine room is computer controlled by night, although the duty engineer will make inspections during unmanned operation. Engineers work in a hot, humid, noisy atmosphere. Communication in the engine room is therefore by hand signals and lip-reading, and good teamwork often stands in place of any communication at all. The environmental impact of shipping includes greenhouse gas emissions , acoustic , and oil pollution . The International Maritime Organization (IMO) estimates that Carbon dioxide emissions from shipping were equal to 2.2% of

1500-469: The British canal system the term 'barge' is no longer used to describe narrowboats and widebeams . Narrowboats and widebeams are still seen on canals, mostly for leisure cruising, and now engine-powered. The people who moved barges were known as lightermen . Poles are used on barges to fend off other nearby vessels or a wharf. These are often called 'pike poles'. The long pole used to maneuver or propel

1550-517: The British river system and larger waterways, the Thames sailing barge , and Dutch barge and unspecified other styles of barge, are still known as barges. The term Dutch barge is nowadays often used to refer to an accommodation ship, but originally refers to the slightly larger Dutch version of the Thames sailing barge. During the Industrial Revolution , a substantial network of canals was developed in Great Britain from 1750 onward. Whilst

1600-753: The Catering Department is headed by the Chief Purser and managed by Assistant Pursers. Although they enjoy the benefits of having officer rank, they generally progress through the ranks to become pursers. Under the pursers are the department heads – such as chief cook, head waiter, head barman etc. They are responsible for the administration of their own areas. The chief steward also plans menus and compiles supply, overtime, and cost control records. They may requisition or purchase stores and equipment. They may bake bread, rolls, cakes, pies, and pastries. A chief steward's duties may overlap with those of

1650-534: The Great Lakes and Canada with New Orleans . Ores, coal, and grains can travel along the rivers of the American Midwest to Pittsburgh or to Birmingham , Alabama. Professional mariners are known as merchant seamen, merchant sailors, and merchant mariners, or simply seamen, sailors, or mariners. The terms "seaman" or "sailor" may also refer to a member of a country's martial navy . According to

1700-733: The attraction is a life unencumbered with the restraints of life ashore. Seagoing adventure and a chance to see the world also appeal to many seafarers. Whatever the calling, those who live and work at sea invariably confront social isolation. Findings by the Seafarer's International Research Center indicate a leading cause of mariners leaving the industry is "almost invariably because they want to be with their families." U.S. merchant ships typically do not allow family members to accompany seafarers on voyages. Industry experts increasingly recognize isolation, stress, and fatigue as occupational hazards. Advocacy groups such as International Labour Organization,

1750-461: The average industrial wage is still very low, such as the Philippines or India . Officers however, come from all over the world and it is not uncommon to mix the nationality of the officers on board ships. Officers are often the recipients of university degrees and have completed vast amounts of training in order to reach their rank. Officers benefit e.g. by having larger, more comfortable cabins and table service for their meals. Contracts average at

1800-545: The case of jet boats, an inboard water jet. In shallow-draft areas, such as the Everglades , some craft, such as the hovercraft , are propelled by large pusher-prop fans. Most modern merchant ships can be placed in one of a few categories, such as: Ocean liners are usually strongly built with a high freeboard to withstand rough seas and adverse conditions encountered in the open ocean, having large capacities for fuel, food and other consumables on long voyages. These were

1850-539: The engine and deck departments work four hours on then have eight hours off watch keeping. However, there are many overtime jobs to be done daily. This cycle repeats endlessly, 24 hours a day while the ship is at sea. Members of the steward department typically are day workers who put in at least eight-hour shifts. Operations at sea, including repairs, safeguarding against piracy , securing cargo, underway replenishment , and other duties provide opportunities for overtime work. Service aboard ships typically extends for months at

1900-463: The engine department. Mariners spend much of their life beyond the reach of land. They sometimes face dangerous conditions at sea or on lakes – the fishing port of Gloucester, Massachusetts has a seaside memorial listing over 10,000 fishermen who lost their lives to the sea, and the Great Lakes have seen over 10,000 lost vessels since the 1800s, yet men and women still go to sea. For some,

1950-502: The final port to the refinery. The Transportation Institute at Texas A&M found that inland barge transportation in the US produces far fewer emissions of carbon dioxide for each ton of cargo moved compared to transport by truck or rail. According to the study, transporting cargo by barge produces 43% less greenhouse gas emissions than rail and more than 800% less than trucks. Environmentalists claim that in areas where barges, tugboats and towboats idle may produce more emissions like in

2000-409: The global human-made emissions in 2012 and expects them to rise 50 to 250 percent by 2050 if no action is taken. The IEA forecasts that ammonia will meet approximately 45% of shipping fuel demands by 2050. For a port to efficiently send and receive cargo, it requires infrastructure : docks, bollards, pilings, cranes, bulk cargo handling equipment, and so on – equipment and organization supporting

2050-414: The largest of these could accommodate ocean-going vessels e.g the later Manchester Ship Canal , a complex network of smaller canals was also developed. These smaller canals had locks, bridges and tunnels that were at minimum only 7 feet (2.1 m) wide at the waterline . On wider sections, standard barges and other vessels could trade, but full access to the network necessitated the parallel development of

2100-586: The locks and dams of the Mississippi River. Self-propelled barges may be used for traveling downstream or upstream in placid waters; they are operated as an unpowered barge, with the assistance of a tugboat, when traveling upstream in faster waters. Canal barges are usually made for the particular canal in which they will operate. Unpowered vessels—barges—may be used for other purposes, such as large accommodation vessels , towed to where they are needed and stationed there as long as necessary. An example

2150-600: The main stay of most passenger transport companies, however, due to the growth of air travel, the passenger ships saw a steady decline. Cruise ships later filled the void and are primarily used by people who still have a love of the sea and offer more amenities than the older passenger ships. A cargo ship sailing from a European port to a US one will typically take 10–12 days depending on water currents and other factors. In order to make container ship transport more economical, ship operators sometimes reduce cruising speed, thereby increasing transit time, to reduce fuel consumption,

2200-443: The most part are strangers, takes getting used to. At the same time, there is an opportunity to meet people from other ethnic and cultural backgrounds. Recreational opportunities have improved aboard some U.S. ships, which may feature gyms and day rooms for watching movies, swapping sea stories , and other activities. And in some cases, especially tankers, it is possible for a mariner to be accompanied by members of his family. However,

2250-664: The river and canal systems connecting inland destinations, large and small. For example, during the early modern era , cities in the Hanseatic League began taming Northern Europe 's rivers and harbors. Similarly, the Saint Lawrence Seaway connects the port cities on the Great Lakes in Canada and the United States with the Atlantic Ocean shipping routes, while the various Illinois canals connect

2300-573: The role of the facilities. From pier to pier these may differ, one dock handling intermodal transport needs (container-ships linked to rail by cranes); another bulk handling capabilities (such as conveyors, elevators, tanks, pumps) for loading and unloading bulk cargoes like grain, coal, or fuels. Others may be outfitted as passenger terminals or for mixed mode operations. Generally, Harbors , seaports and marinas all host watercraft, and consist of components such as piers , wharfs , docks and roadsteads . Barge Barge typically refers to

2350-525: The sailing scow. The innovation that led to the modern barge was the use of iron barges towed by a steam tugboat. These were first used to transport grain and other bulk products. From about 1840 to 1870 the towed iron barge was quickly introduced on the Rhine, Danube, Don, Dniester , and rivers in Egypt, India and Australia. Many of these barges were built in Great Britain. Nowadays 'barge' generally refers to

2400-458: Was also a radio department, headed by a chief radio officer and supported by a number of radio officers. Since the introduction of GMDSS (Satellite communications) and the subsequent exemptions from carrying radio officers if the vessel is so equipped, this department has fallen away, although many ships do still carry specialist radio officers, particularly passenger vessels. Many radio officers became 'electro-technical officers', and transferred into

2450-671: Was shipped by barge from the Tulsa Port of Catoosa in Oklahoma to a refinery in Pascagoula, Mississippi . Extremely large objects are normally shipped in sections and assembled after delivery, but shipping an assembled unit reduces costs and avoids reliance on construction labor at the delivery site, which in the case of the reactor was still recovering from Hurricane Katrina . Of the reactor's 700-mile (1,100 km) journey, only about 40 miles (64 km) were traveled overland, from

2500-416: Was that any flat that was not propelled by steam was a barge, although it might be a sailing flat. The term Dumb barge was probably taken into use to end the confusion. The term Dumb barge surfaced in the early nineteenth century. It first denoted the use of a barge as a mooring platform in a fixed place. As it went up and down with the tides, it made a very convenient mooring place for steam vessels. Within
