Container ships are cargo ships that carry all of their load in truck-size intermodal containers, in a technique called containerization.
The earliest container ships were converted tankers, built up from surplus T2 tankers after World War II. In 1955, McLean built his company, McLean Trucking into one of USA’s biggest freighter fleets. Container vessels eliminate the individual hatches, holds and dividers of the traditional general cargo vessels.
Shipping containers are usually made of steel, but other materials like aluminium, fibreglass or plywood are also used. Coming back to McLean’s invention, while it is a well established fact that containerization caused a revolution in the world of shipping its introduction did not have an easy passage. Containerization changed not only the face of shipping but it also revolutionised world trade as well. Exporters load (stuff) their merchandise in boxes that are provided by the shipping companies. Cranes, installed either on the pier or on the ship, are used to place containers on board the ship. Containerization has lowered shipping costs and decreased shipping time, and this has in turn helped the growth of international trade. It has resulted in such revolutions as on time guaranteed delivery and just in time manufacturing. USNS Regulus (T-AKR-292) began its career as Sea-Land's SL-7 class container ship MV Sea-Land Commerce. The hull of a modern cargo ship is a complex arrangement of steel plates and strengthening beams. With a beam of 43 m, ships of the COSCO Guangzhou class are much too big to fit through the Panama Canal's old locks, but could easily fit through the new expansion. Container ships under 3,000 TEU are typically called feeders, and are most likely to have cargo cranes. A major characteristic of a container ship is whether it has cranes installed for handling its cargo. International law requires that every merchant ship be registered in a country, called its flag state.[42] 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. In recent years, oversupply of container ship capacity has caused prices for new and used ships to fall.

Economies of scale have dictated an upward trend in sizes of container ships in order to reduce costs. Since even very large container ships are vessels with relatively low draft compared to large tankers and bulk carriers, there is still considerable room for vessel growth.
In the present market situation, main engines will not be as much of a limiting factor for vessel growth either. UNCTAD uses the Hamburg Shipbrokers’ Association (formally the Vereinigung Hamburger Schiffsmakler und Schiffsagenten e. Since 2006 we have been providing an ever expanding collecton of free to use travel themed stock images. In 1931, McLean purchased his first truck to send and pick up loads to and from vessels in various ports. In 1951 the first purpose-built container vessels began operating in Denmark, and between Seattle and Alaska. The hull of a typical container ship is a huge warehouse divided into cells by vertical guide rails. They are designed to be entirely transferred to and from trains, trucks or trailers to and from a ship. As a class, container ships now rival crude oil tankers and bulk carriers as the largest commercial vessels on the ocean. Shipping lines, railway (railroad in the US) companies and trade unions vehemently opposed and tried to block the use of containerised ships. A container ship can be loaded and unloaded in a few hours compared to days in a traditional cargo vessel. They are then delivered to the docks by road, rail or a combination of both for loading on to container ships.
Cargo that once arrived in cartons, crates, bales, barrels or bags now comes in factory sealed containers, with no indication to the human eye of their contents, except for a product code that machines can scan and computers trace.
Raw materials arrive in factories in sealed containers less than an hour before they are required in manufacture, resulting in reduced inventory costs.
Those that have cargo cranes are called geared and those that don't are called ungeared or gearless.
Until the 1950s, hatches were typically secured with wooden boards and tarpaulins held down with battens.[29] 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. The steadily rising cost of fuel oil has 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.

During this time, while he used to wait impatiently for the truck’s contents to be loaded on to the ship he kept thinking of a more efficient and quick way to load and unload vessels and thus save enormous time and labor. There are several types of containers and they are categorised according to their size and functions. It took ten years of legal battles before container ships would be pressed into international service. This, besides cutting labor costs, has reduced shipping times between points to a great extent, for example it takes a few weeks instead of months for a consignment to be delivered from India to Europe and vice versa. Prior to containerization, huge gangs of men would spend hours fitting various items of cargo into different holds. This system of tracking has been so exact that a two week voyage can be timed for arrival with an accuracy of under fifteen minutes.
Into this frame is set one or more below-deck cargo holds, numerous tanks, and the engine room. 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. It has also resulted in less breakage due to less handling and there is less danger of cargo shifting during a voyage.
Furthermore, the permissible maximum ship dimensions in some of the world's main waterways could present an upper limit in terms of vessel growth. 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 is still above that of any conceivable container ship design. As containers are sealed and only open at the destination, pilferage and theft levels have been greatly reduced. Many container ships have cargo cranes installed on them, and some have specialized systems for securing containers on board.
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.[76] The ships will be delivered between 2013 and 2014.
