82-488: Container ship capacity is measured in twenty-foot equivalent units (TEU). Typical loads are a mix of 20-foot (1-TEU) and 40-foot (2-TEU) ISO-standard containers , with the latter predominant. Today, about 90% of non- bulk cargo worldwide is transported by container ships, the largest of which, from 2023 onward, can carry over 24,000 TEU. There are two main types of dry cargo: bulk cargo and break bulk cargo . Bulk cargoes, like grain or coal, are transported unpackaged in

164-627: A "dramatic decline" of approximately 75%, which lasted until rates stabilized in April 2009. Rates have ranged from $ 2.70 to $ 35.40 in this period, with prices generally lower on larger ships. The most resilient sized vessel in this time period were those from 200 to 300 TEU, a fact that the United Nations Council on Trade and Development attributes to lack of competition in this sector. Overall, in 2010, these rates rebounded somewhat, but remained at approximately half of their 2008 values. As of 2011,

246-618: A combination is within the limits of national road regulations in many countries, requiring no special permission. As some road regulations allow longer trucks, there are also variations of the standard 40-foot container; in Europe and most other places a container of 45 feet (13.72 m) may be pulled as a trailer. Containers with a length of 48 feet (14.63 m) or 53 feet (16.15 m) are restricted to road and rail transport in North America. Although longer than 40 feet, these variants are put in

328-402: A gearless ship. Geared ships also incur greater recurring expenses, such as maintenance and fuel costs. The United Nations Council on Trade and Development characterizes geared ships as a "niche market only appropriate for those ports where low cargo volumes do not justify investment in port cranes or where the public sector does not have the financial resources for such investment". Instead of

410-522: A key to the success of the container ship. The first crane that was specifically designed for container work was built in California's Port of Alameda in 1959. By the 1980s, shoreside gantry cranes were capable of moving containers on a 3-minute-cycle, or up to 400 tons per hour. In March 2010, at Port Klang in Malaysia, a new world record was set when 734 container moves were made in a single hour. The record

492-466: A maximum weight of 67,200 pounds (30,500 kg), an empty weight of 5,290 pounds (2,400 kg), and a net load of 61,910 pounds (28,080 kg). Cargo ship A cargo ship or freighter is a merchant ship that carries cargo , goods , and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade . Cargo ships are usually specially designed for

574-608: A merchant ship's prefix, denotes that it is a T urbine S teamer. Famous cargo ships include the 2,710 Liberty ships of World War II , partly based on a British design . Liberty ship sections were prefabricated in locations across the United States and then assembled by shipbuilders in an average of six weeks, with the record being just over four days. These ships allowed the Allies in World War II to replace sunken cargo vessels at

656-597: A moulded breadth over 32.31 m, however the Panama Canal expansion project has caused some changes in terminology. The Neopanamax category is based on the maximum vessel size that is able to transit a new third set of locks, which opened in June 2016. The third set of locks were built to accommodate a container ship with a length overall of 366 metres (1,201 ft), a maximum beam (width) of 49 metres (161 ft), and tropical fresh-water draft of 15.2 metres (50 ft). Such

738-529: A narrow channel between Indonesia and Singapore / Malaysia , and cargo ships are still commonly targeted. In 2004, the governments of those three nations agreed to provide better protection for the ships passing through the Straits. The waters off Somalia and Nigeria are also prone to piracy, while smaller vessels are also in danger along parts of the South American coasts, Southeast Asian coasts, and near

820-509: A new " Triple E " family of container ships with a capacity of 18,000 TEU, with an emphasis on lower fuel consumption. In the present market situation, main engines will not be as much of a limiting factor for vessel growth either. The steadily rising expense of fuel oil in the early 2010s had prompted most container lines to adapt a slower, more economical voyage speed of about 21 knots, compared to earlier top speeds of 25 or more knots. Subsequently, newly built container ships can be fitted with

902-557: A rate greater than the Kriegsmarine 's U-boats could sink them, and contributed significantly to the war effort, the delivery of supplies, and eventual victory over the Axis powers. Liberty ships were followed by the faster Victory ships . Canada built Park ships and Fort ships to meet the demand for the Allies shipping. The United Kingdom built Empire ships and used US Ocean ships . After

984-606: A second watertight shell that runs most of the length of a ship. The double-bottoms generally hold liquids such as fuel oil, ballast water or fresh water. A ship's engine room houses its main engines and auxiliary machinery such as the fresh water and sewage systems, electrical generators, fire pumps, and air conditioners. In most new ships, the engine room is located in the aft portion. Container ships are distinguished into 7 major size categories: small feeder, feeder, feedermax, Panamax , Post-Panamax , Neopanamax and ultra-large. As of December 2012, there were 161 container ships in

1066-539: A smaller main engine. Engine types fitted to today's ships of 14,000  TEU are thus sufficiently large to propel future vessels of 20,000  TEU or more. Maersk Line, the world's largest container shipping line, nevertheless opted for twin engines (two smaller engines working two separate propellers), when ordering a series of ten 18,000 TEU vessels from Daewoo Shipbuilding in February 2011. The ships were delivered between 2013 and 2014. In 2016, some experts believed that

1148-479: A standard-sized metal box that can be easily transferred between different modes of transportation, such as ships, trains, and trucks. The standard intermodal container is 19 feet 10.5 inches (6.058 m) long and eight feet (2.44 m) wide. The height of such containers is most commonly 8 feet 6 inches (2.59 m) but ranges from 4 feet 3 inches (1.30 m) to 9 feet 6 inches (2.90 m). Another standard container

1230-521: A vessel, called Neopanamax class, is wide enough to carry 19 columns of containers, can have a total capacity of approximately 12,000 TEU and is comparable in size to a capesize bulk carrier or a Suezmax tanker. Container ships under 3,000 TEU are generally called feeder ships or feeders. They are small ships that typically operate between smaller container ports. Some feeders collect their cargo from small ports, drop it off at large ports for transshipment on larger ships, and distribute containers from

1312-445: A volume range of 680 to 1,520 cubic feet (19 to 43 m ) for one TEU. While the TEU is not itself a measure of mass, some conclusions can be drawn about the maximum mass that a TEU can represent. The maximum gross mass for a 20-foot (6.1 m) dry cargo container is 24,000 kilograms (53,000 lb). Subtracting the tare mass of the container itself, the maximum amount of cargo per TEU

1394-503: Is a chartering price, specifically the price to time-charter a 1 TEU slot for 14 tonnes of cargo on a container ship. The other is the freight rate ; or comprehensive daily cost to deliver one-TEU worth of cargo on a given route. As a result of the late-2000s recession , both indicators showed sharp drops during 2008–2009, and have shown signs of stabilization since 2010. UNCTAD uses the Hamburg Shipbrokers' Association (formally

1476-492: Is built around a strong keel . Into this frame is set one or more below-deck cargo holds , numerous tanks, and the engine room . The holds are topped by hatch covers, onto which more containers can be stacked. Many container ships have cargo cranes installed on them, and some have specialized systems for securing containers on board. The hull of a modern cargo ship is a complex arrangement of steel plates and strengthening beams. Resembling ribs, and fastened at right angles to

1558-437: Is constructed of forged steel and ductile iron and has a shear strength of 48 tonnes. The buttress system, used on some large container ships, uses a system of large towers attached to the ship at both ends of each cargo hold. As the ship is loaded, a rigid, removable stacking frame is added, structurally securing each tier of containers together. Container ships have typically had a single bridge and accommodation unit towards

1640-547: Is defined as two TEU. It is common to designate a 45-foot (13.7 m) container as 2 TEU, rather than 2.25 TEU. The most common twenty-foot container occupies a space 20 feet (6.1 m) long, 8 feet (2.44 m) wide, and 8 feet 6 inches (2.59 m) high, with an allowance externally for the corner castings ; the internal volume is 1,172 cubic feet (33.2 m ). However, both 9-foot-6-inch-tall (2.90 m) High cube and 4-foot-3-inch (1.30 m) half height containers are also reckoned as 1 TEU. This gives

1722-413: Is increased by securing containers to each other, either by simple metal forms (such as stacking cones) or more complicated devices such as twist-lock stackers. A typical twist-lock is inserted into the casting hole of one container and rotated to hold it in place, then another container is lowered on top of it. The two containers are locked together by twisting the device's handle. A typical twist-lock

1804-433: Is increasing: with bunker fuel consumption at 278 million tonnes per year in 2001, it is projected to be at 500 million tonnes per year in 2020. International standards to dramatically reduce sulphur content in marine fuels and nitrogen oxide emissions have been put in place. Among some of the solutions offered is changing over the fuel intake to clean diesel or marine gas oil, while in restricted waters and cold ironing

1886-593: Is moved at once and each container is secured to the ship once in a standardized way. Containerization has increased the efficiency of moving traditional break-bulk cargoes significantly, reducing shipping time by 84% and costs by 35%. In 2001, more than 90% of world trade in non-bulk goods was transported in ISO containers. In 2009, almost one quarter of the world's dry cargo was shipped by container, an estimated 125 million TEU or 1.19 billion tonnes worth of cargo. The first ships designed to carry standardized load units were used in

1968-552: Is one of four ordered from the builder in 2020, and exceeded MSC's 24,116 TEU MSC Tessa , which had been delivered that same day by the China State Shipbuilding Corporation (CSSC). In April, MSC Irina sister ship MSC Loreto , with an equal capacity of 24,346 TEU was received by MSC. On June 2, 2023 Ocean Network Express took delivery of the ONE Innovation with a capacity of 24,136 TEUs. ONE Innovation

2050-463: Is one of six new Megamax vessels ordered by Ocean Network Express in December 2020 to be built by a consortium of Imabari Shipbuilding and Japan Marine United . The act of hiring a ship to carry cargo is called chartering. Outside special bulk cargo markets, ships are hired by three types of charter agreements: the voyage charter , the time charter, and the bareboat charter . In a voyage charter,

2132-465: Is reduced to about 21,600 kilograms (47,600 lb). Similarly, the maximum gross mass for a 40-foot (12.2 m) dry cargo container (including the 9-foot-6-inch (2.90 m) High cube container) is 30,480 kilograms (67,200 lb). After correcting for tare weight, this gives a cargo capacity of 26,500 kilograms (58,400 lb). Twenty-foot "heavy tested" containers are available for heavy goods such as heavy machinery. These containers allow

2214-539: Is slightly more than twice as long: 40-foot (12.19 m), dubbed a forty-foot equivalent unit (often FEU or feu ). The reason the smaller container is 1.5 inches short of 20 feet is to allow it to be stacked efficiently with 40-foot containers. The twistlocks on a ship are set so that two standard 20-foot containers have a gap of three inches, allowing a single 40-foot container to fit precisely on top. The 40-foot containers have found wider acceptance, as they can be pulled by semi-trailer trucks . The length of such

2296-498: Is still considerable room for vessel growth. Compared to today's largest container ships, Maersk Line's 15,200  TEU Emma Mærsk -type series, a 20,000  TEU container ship would only be moderately larger in terms of exterior dimensions. According to a 2011 estimate, an ultra-large container ship of 20,250  TEU would measure 440 m × 59 m (1,444 ft × 194 ft), compared to 397.71 m × 56.40 m (1,304.8 ft × 185.0 ft) for

2378-614: Is the use of cell guides . Cell guides are strong vertical structures constructed of metal installed into a ship's cargo holds. These structures guide containers into well-defined rows during loading and provide some support for containers against the ship's rolling at sea. So fundamental to container ship design are cell guides that organizations such as the United Nations Conference on Trade and Development use their presence to distinguish dedicated container ships from general break-bulk cargo ships. A system of three dimensions

2460-442: Is transported by container by about 50,000 container ships. Modern container ships can carry over 24,000 TEU. The largest container ships measure about 400 metres (1,300 ft) in length, and carry loads equal to the cargo-carrying capacity of sixteen to seventeen pre-World War II freighter ships. There are several key points in the design of modern container ships. The hull, similar to that of bulk carriers and general cargo ships,

2542-416: Is used in cargo plans to describe the position of a container aboard the ship. The first coordinate is the bay , which starts at the front of the ship and increases aft. The second coordinate is the row . Rows on the starboard side are given odd numbers and those on the port side are given even numbers. The rows nearest the centerline are given low numbers, and the numbers increase for slots further from

2624-717: The Caribbean Sea . A category designation appears before the vessel's name. A few examples of prefixes for naval ships are "USS" ( United States Ship ), "HMS" ( Her/His Majesty’s Ship ), "HMCS" ( Her/His Majesty's Canadian Ship ) and "HTMS" (His Thai Majesty's Ship), while a few examples for prefixes for merchant ships are "RMS" ( Royal Mail Ship , usually a passenger liner), "MV" ( Motor Vessel , powered by diesel ), "MT" (Motor Tanker, powered vessel carrying liquids only) "FV" Fishing Vessel and "SS" ( Screw Steamer , driven by propellers or screws, often understood to stand for Steamship ). "TS", sometimes found in first position before

2706-657: The Clifford J. Rogers , built in 1955, and introduced containers to its railway in 1956. MV Kooringa was the world's first fully cellular , purpose-built container ship. and was built by Australian company Associated Steamships, a partnership formed by the 1964 merger of the Adelaide Steamship Company with McIlwraith, McEacharn & Co , then commissioned in May 1964. Container ships were designed to accommodate intermodal transport of goods, and eliminated requirements for

2788-551: The Emma Mærsk class. It would have an estimated deadweight of circa 220,000 tons. While such a vessel might be near the upper limit for a Suez Canal passage, the so-called Malaccamax concept (for Straits of Malacca ) does not apply for container ships, since the Malacca and Singapore Straits' draft limit of about 21 metres (69 ft) is still above that of any conceivable container ship design. In 2011, Maersk announced plans to build

2870-503: The European Union is planning stricter controls on emissions. Cargo ships have been reported to have a possible negative impact on the population of whale sharks. Smithsonian Magazine reported in 2022 that whale sharks , the largest species of fish, have been disappearing mysteriously over the past 75 years, with research pointing to cargo ships and large vessels as the likely culprits. A study involving over 75 researchers highlighted

2952-656: The Suez Canal and the Singapore Strait . In 2008 the South Korean shipbuilder STX announced plans to construct a container ship capable of carrying 22,000  TEU , and with a proposed length of 450 m (1,480 ft) and a beam of 60 m (200 ft). If constructed, the container ship would become the largest seagoing vessel in the world. Since even very large container ships are vessels with relatively low draft compared to large tankers and bulk carriers, there

3034-586: The Vereinigung Hamburger Schiffsmakler und Schiffsagenten e. V. or VHSS for short) as its main industry source for container ship freight prices. The VHSS maintains a few indices of container ship charter prices. The oldest, which dates back to 1998, is called the Hamburg Index . This index considers time-charters on fully cellular container ships controlled by Hamburg brokers. It is limited to charters of 3 months or more, and presented as

3116-522: The United States and Japan only had 75 and 11 registered container ships, respectively. In recent years, oversupply of container ship capacity has caused prices for new and used ships to fall. From 2008 to 2009, new container ship prices dropped by 19–33%, while prices for 10-year-old container ships dropped by 47–69%. In March 2010, the average price for a geared 500-TEU container ship was $ 10 million, while gearless ships of 6,500 and 12,000 TEU averaged prices of $ 74 million and $ 105 million respectively. At

3198-467: The VLCS class (Very Large Container Ships, more than 10,000 TEU), and 51 ports in the world can accommodate them. The size of a Panamax vessel is limited by the original Panama canal's lock chambers , which can accommodate ships with a beam of up to 32.31 m, a length overall of up to 294.13 m, and a draft of up to 12.04 m. The Post-Panamax category has historically been used to describe ships with

3280-673: The average daily cost in U.S. dollars for a one-TEU slot with a weight of 14 tonnes. The Hamburg Index data is divided into ten categories based primarily on vessel carrying capacity. Two additional categories exist for small vessels of under 500 TEU that carry their own cargo cranes. In 2007, VHSS started another index, the New ConTex which tracks similar data obtained from an international group of shipbrokers. The Hamburg Index shows some clear trends in recent chartering markets. First, rates were generally increasing from 2000 to 2005. From 2005 to 2008, rates slowly decreased, and in mid-2008 began

3362-408: The canal locks a ship can fit in, water depth ( draft ) is a limitation for canals, shallow straits or harbors and height is a limitation in order to pass under bridges. Common categories include: [REDACTED] The TI-class supertanker is an Ultra Large Crude Carrier, with a draft that is deeper than Suezmax, Malaccamax and Neopanamax. This causes Atlantic/Pacific routes to be very long, such as

3444-481: The centerline. The third coordinate is the tier , with the first tier at the bottom of the cargo holds, the second tier on top of that, and so forth. Container ships typically take 20 foot and 40 foot containers. Some ships can take 45 footers above deck. A few ships (APL since 2007, Carrier53 since 2022 ) can carry 53 foot containers. 40 foot containers are the primary container size, making up about 90% of all container shipping and since container shipping moves 90% of

3526-585: The charterer rents the vessel from the loading port to the discharge port. In a time charter, the vessel is hired for a set period of time, to perform voyages as the charterer directs. In a bareboat charter, the charterer acts as the ship's operator and manager, taking on responsibilities such as providing the crew and maintaining the vessel. The completed chartering contract is known as a charter party . The United Nations Conference on Trade and Development [UNCTAD], tracks in its 2010 Review of Maritime Trade two aspects of container shipping prices: The first one

3608-420: The containers together. Above-decks, without the extra support of the cell guides, more complicated equipment is used. Three types of systems are currently in wide use: lashing systems, locking systems, and buttress systems. Lashing systems secure containers to the ship using devices made from wire rope, rigid rods, or chains and devices to tension the lashings, such as turnbuckles. The effectiveness of lashings

3690-432: The current largest container ships are at the optimum size, and could not economically be larger, as port facilities would be too expensive, port handling too time consuming, the number of suitable ports too low, and insurance cost too high. In March 2017 the first ship with an official capacity over 20,000 TEUs was christened at Samsung Heavy Industries . MOL Triumph has a capacity of 20,150 TEUs. Samsung Heavy Industries

3772-410: The design of container ships. While containers may be carried on conventional break-bulk ships, cargo holds for dedicated container ships are specially constructed to speed loading and unloading, and to efficiently keep containers secure while at sea. A key aspect of container ship specialization is the design of the hatches, the openings from the main deck to the cargo holds. The hatch openings stretch

3854-532: The entire breadth of the cargo holds, and are surrounded by a raised steel structure known as the hatch coaming . On top of the hatch coamings are the hatch covers. Until the 1950s, hatches were typically secured with wooden boards and tarpaulins held down with battens. Today, some hatch covers can be solid metal plates that are lifted on and off the ship by cranes, while others are articulated mechanisms that are opened and closed using powerful hydraulic rams. Another key component of dedicated container-ship design

3936-683: The first container ship in the world was launched; the Autocarrier , owned by the Southern Railway. It had 21 slots for containers of Southern Railway. The earliest container ships after the Second World War were converted oil tankers , built up from surplus T2 tankers after World War II. In 1951, the first purpose-built container vessels began operating in Denmark , and between Seattle and Alaska . The first commercially successful container ship

4018-599: The first of these rebuilt container vessels, Ideal X , left the Port Newark in New Jersey and a new revolution in modern shipping resulted. In the 1950s, a new standardized steel Intermodal container based on specifications from the United States Department of Defense began to revolutionize freight transportation. The White Pass & Yukon Route railway acquired the world's first purpose built container ship,

4100-498: The hull of the ship, generally in large volume. Break-bulk cargoes, in contrast, are transported in packages, and are generally manufactured goods. Before the advent of containerization in the 1950s, break-bulk items required manual loading, lashing, unlashing and unloading from the ship one piece at a time. This stevedoring process became more efficient by grouping cargo into containers, 1,000 to 3,000 cubic feet (28 to 85 m) of cargo, or up to about 64,000 pounds (29,000 kg),

4182-447: The index shows signs of recovery for container shipping, and combined with increases in global capacity, indicates a positive outlook for the sector in the near future. Twenty-foot equivalent unit The twenty-foot equivalent unit (abbreviated TEU or teu ) is a general unit of cargo capacity, often used for container ships and container ports . It is based on the volume of a 20-foot-long (6.1 m) intermodal container ,

4264-600: The individual hatches, holds and other dividers of traditional cargo ships . The hull of a typical container ship is similar to an airport hangar, or a huge warehouse, which is divided into individual holding cells, using vertical guide rails. The ship's cells are designed to hold cargo containers, which are typically constructed of steel, though sometimes of aluminum, fiberglass or plywood, and designed for intermodal transfers between ship and train , truck or semi-trailer . Shipping containers are categorized by type, size and function. Today, about 90% of non- bulk cargo worldwide

4346-435: The keel, are the ship's frames. The ship's main deck, the metal platework that covers the top of the hull framework, is supported by beams that are attached to the tops of the frames and run the full breadth of the ship. The beams not only support the deck, but along with the deck, frames, and transverse bulkheads, strengthen and reinforce the shell. Another feature of recent hulls is a set of double-bottom tanks, which provide

4428-415: The large port to smaller regional ports. This size of vessel is the most likely to carry cargo cranes on board. A major characteristic of a container ship is whether it has cranes installed for handling its cargo. Those that have cargo cranes are called geared and those that do not are called ungeared or gearless . The earliest purpose-built container ships in the 1970s were all gearless. Since then,

4510-738: The late 18th century in England. In 1766 James Brindley designed the box boat "Starvationer" with 10 wooden containers, to transport coal from Worsley Delph to Manchester via the Bridgewater Canal . Before the Second World War , the first container ships were used to carry the baggage of the luxury passenger train from London to Paris ( Southern Railway's Golden Arrow / La Flèche d'Or ). These containers were loaded in London or Paris, and carried to ports of Dover or Calais on flat cars. In February 1931,

4592-697: The locks on the Saint Lawrence Seaway . The earliest records of waterborne activity mention the carriage of items for trade; the evidence of history and archaeology shows the practice to be widespread by the beginning of the 1st millennium BC, and as early as the 14th and 15th centuries BC small Mediterranean cargo ships like those of the 50 foot long (15–16 metre) Uluburun ship were carrying 20 tons of exotic cargo; 11 tons of raw copper, jars, glass, ivory, gold, spices, and treasures from Canaan , Greece , Egypt , and Africa . The desire to operate trade routes over longer distances, and throughout more seasons of

4674-530: The long voyages south of Cape of Good Hope or south of Cape Horn to transit between Atlantic and Pacific oceans. Lake freighters built for the Great Lakes in North America differ in design from sea water–going ships because of the difference in wave size and frequency in the lakes. A number of these ships are larger than Seawaymax and cannot leave the lakes and pass to the Atlantic Ocean, since they do not fit

4756-403: The percentage of geared newbuilds has fluctuated widely, but has been decreasing overall, with only 7.5% of the container ship capacity in 2009 being equipped with cranes. While geared container ships are more flexible in that they can visit ports that are not equipped with pierside container cranes , they suffer from several drawbacks. To begin with, geared ships will cost more to purchase than

4838-506: The rear, but to reconcile demand for larger container capacity with SOLAS visibility requirements, several new designs have been developed. As of 2015, some large container ships are being developed with the bridge further forward, separate from the exhaust stack. Some smaller container ships working in European ports and rivers have liftable wheelhouses, which can be lowered to pass under low bridges. As of 2010, container ships made up 13.3% of

4920-410: The rotary cranes, some geared ships have gantry cranes installed. These cranes, specialized for container work, are able to roll forward and aft on rails. In addition to the additional capital expense and maintenance costs, these cranes generally load and discharge containers much more slowly than their shoreside counterparts. The introduction and improvement of shoreside container cranes have been

5002-499: The same class of forty-foot equivalent units. The carrying capacity of a ship is usually measured by mass (the deadweight tonnage ) or by volume (the net register tonnage ). Deadweight tonnage is generally measured now in metric tons ( tonnes ). Register tons are measured in cu. ft, with one register ton equivalent to 100 cubic feet (2.83 m ). As the TEU is an inexact unit, it cannot be converted precisely into other units. The related unit forty-foot equivalent unit , however,

5084-506: The same time, secondhand prices for 10-year-old geared container ships of 500-, 2,500-, and 3,500-TEU capacity averaged prices of $ 4 million, $ 15 million, and $ 18 million respectively. In 2009, 11,669,000 gross tons of newly built container ships were delivered. Over 85% of this new capacity was built in the Republic of Korea, China, and Japan, with Korea accounting for over 57% of the world's total alone. New container ships accounted for 15% of

5166-581: The scrap metal market. Scrapping rates are volatile, the price per light ton displacement has swung from a high of $ 650 per LTD in mid-2008 to $ 200 per LTD in early 2009, before building to $ 400 per LTD in March 2010. As of 2009, over 96% of the world's scrapping activity takes place in China, India, Bangladesh, and Pakistan. The global economic downturn of 2008–2009 resulted in more ships than usual being sold for scrap. In 2009, 364,300 TEU worth of container ship capacity

5248-489: The ship for hire, while "freight" refers to the act of carrying of such cargo, but the terms have been used interchangeably for centuries. Generally, the modern ocean shipping business is divided into two classes: Larger cargo ships are generally operated by shipping lines : companies that specialize in the handling of cargo in general. Smaller vessels, such as coasters , are often owned by their operators. Cargo ships/freighters can be divided into eight groups, according to

5330-504: The ship while it is in port. The process of removing sulphur from the fuel impacts the viscosity and lubricity of the marine gas oil though, which could cause damage in the engine fuel pump . The fuel viscosity can be raised by cooling the fuel down. If the various requirements are enforced, the International Maritime Organization 's marine fuel requirement will mean a 90% reduction in sulphur oxide emissions; whilst

5412-400: The size of container ships. Primarily, these are the availability of sufficiently large main engines and the availability of a sufficient number of ports and terminals prepared and equipped to handle ultra-large container ships. Furthermore, the permissible maximum ship dimensions in some of the world's main waterways could present an upper limit in terms of vessel growth. This primarily concerns

5494-593: The smaller shipping companies and private individuals operate tramp ships. Cargo liners run on fixed schedules published by the shipping companies. Each trip a liner takes is called a voyage. Liners mostly carry general cargo. However, some cargo liners may carry passengers also. A cargo liner that carries 12 or more passengers is called a combination or passenger-run-cargo line. Cargo ships are categorized partly by cargo or shipping capacity ( tonnage ), partly by weight ( deadweight tonnage DWT), and partly by dimensions. Maximum dimensions such as length and width ( beam ) limit

5576-400: The task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel , and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped. The words cargo and freight have become interchangeable in casual usage. Technically, "cargo" refers to the goods carried aboard

5658-619: The tonnage of the top 20 liner companies was chartered-in in this manner. International law requires that every merchant ship be registered in a country, called its flag state . A ship's flag state exercises regulatory control over the vessel and is required to inspect it regularly, certify the ship's equipment and crew, and issue safety and pollution prevention documents. As of 2006, the United States Bureau of Transportation Statistics count 2,837 container ships of 10,000 long tons deadweight (DWT) or greater worldwide. Panama

5740-408: The total new tonnage that year, behind bulk carriers at 28.9% and oil tankers at 22.6%. Most ships are removed from the fleet through a process known as scrapping . Scrapping is rare for ships under 18 years old and common for those over 40 years in age. Ship-owners and buyers negotiate scrap prices based on factors such as the ship's empty weight (called light ton displacement or LTD) and prices in

5822-533: The type of cargo they carry. These groups are: Specialized types of cargo vessels include container ships and bulk carriers (technically tankers of all sizes are cargo ships, although they are routinely thought of as a separate category). Cargo ships fall into two further categories that reflect the services they offer to industry: liner and tramp services. Those on a fixed published schedule and fixed tariff rates are cargo liners. Tramp ships do not have fixed schedules. Users charter them to haul loads. Generally,

5904-775: The war many of the ships were sold to private companies. The Ever Given is a ship that was lodged into the Suez Canal from March 25 to 28, 2021, which caused a halt on maritime trade. The MV Dali , which collided with the Francis Scott Key Bridge in Baltimore , Maryland , United States , on 26 March 2024, causing a catastrophic structural failure of the bridge that resulted in at least 6 deaths. Due to its low cost, most large cargo vessels are powered by bunker fuel , also known as heavy fuel oil, which contains higher sulphur levels than diesel. This level of pollution

5986-401: The world's fleet in terms of deadweight tonnage. The world's total of container ship deadweight tonnage has increased from 11 million  DWT in 1980 to 169.0 million  DWT in 2010. The combined deadweight tonnage of container ships and general cargo ships, which also often carry containers, represents 21.8% of the world's fleet. As of 2009, the average age of container ships worldwide

6068-424: The world's freight, over 80% of the world's freight moves via 40 foot containers. Numerous systems are used to secure containers aboard ships, depending on factors such as the type of ship, the type of container, and the location of the container. Stowage inside the holds of fully cellular (FC) ships is simplest, typically using simple metal forms called container guides, locating cones, and anti-rack spacers to lock

6150-502: The world's fully cellular container capacity, with 2,673 vessels of an average capacity of 3,774 TEU. The remaining 6,862 fully cellular ships have an average capacity of 709 TEU each. The vast majority of the capacity of fully cellular container ships used in the liner trade is owned by German shipowners , with approximately 75% owned by Hamburg brokers. It is a common practice for the large container lines to supplement their own ships with chartered-in ships, for example in 2009, 48.9% of

6232-563: The year, motivated improvements in ship design during the Middle Ages . Before the middle of the 19th century, the incidence of piracy resulted in most cargo ships being armed, sometimes quite heavily, as in the case of the Manila galleons and East Indiamen . They were also sometimes escorted by warships . Piracy is still quite common in some waters, particularly in the Malacca Straits ,

6314-449: Was Ideal X , a T2 tanker, owned by Malcom McLean , which carried 58 metal containers between Newark, New Jersey and Houston, Texas , on its first voyage. In 1955, McLean built his company, McLean Trucking into one of the United States' biggest freighter fleets. In 1955, he purchased the small Pan Atlantic Steamship Company from Waterman Steamship and adapted its ships to carry cargo in large uniform metal containers. On April 26, 1956,

6396-400: Was 10.6 years, making them the youngest general vessel type, followed by bulk carriers at 16.6 years, oil tankers at 17 years, general cargo ships at 24.6 years, and others at 25.3 years. Most of the world's carrying capacity in fully cellular container ships is in the liner service , where ships trade on scheduled routes. As of January 2010, the top 20 liner companies controlled 67.5% of

6478-452: Was achieved using 9 cranes to simultaneously load and unload MV  CSCL Pusan , a ship with a capacity of 9,600 TEU. Vessels in the 1,500–2,499 TEU range are the most likely size class to have cranes, with more than 60% of this category being geared ships. Slightly less than a third of the very smallest ships (from 100–499 TEU) are geared, and almost no ships with a capacity of over 4,000 TEU are geared. Efficiency has always been key in

6560-478: Was expected to deliver several ships of over 20,000 TEUs in 2017, and has orders for at least ten vessels in that size range for OOCL and MOL. The world's largest container ship, MSC Irina , was delivered March 9, 2023 by builder Yangzi Xinfu Shipbuilding to the Mediterranean Shipping Company (MSC), with a capacity of 24,346 TEUs. Measuring 399.99 metres in length and 61.3 metres in beam, the ship

6642-476: Was scrapped, up from 99,900 TEU in 2008. Container ships accounted for 22.6% of the total gross tonnage of ships scrapped that year. Despite the surge, the capacity removed from the fleet only accounted for 3% of the world's container ship capacity. The average age of container ships scrapped in 2009 was 27.0 years. Economies of scale have dictated an upward trend in the size of container ships in order to reduce expenses. However, there are certain limitations to

6724-713: Was the world's largest flag state for container ships, with 541 of the vessels in its registry. Seven other flag states had more than 100 registered container ships: Liberia (415), Germany (248), Singapore (177), Cyprus (139), the Marshall Islands (118) and the United Kingdom (104). The Panamanian, Liberian, and Marshallese flags are open registries and considered by the International Transport Workers' Federation to be flags of convenience . By way of comparison, traditional maritime nations such as
