Along with the popularity of the specialized form of container transport, container ships are also increasingly developing in terms of both transport capacity and specialization.
History of container ships
The first container ship converted from the T2 tanker after World War II. Initially, most of the containers were shipped on general cargo ships. In 1951, the first purpose-built container ships began operating in Denmark, and between Seattle and Texas, USA.
In the US, the first container ship, Ideal-X (also converted from a T2 tanker) owned by Malcolm McLean, carried 58 containers from Newark, New Jersey to Houston, Texas, USA on its maiden voyage in April 1956.
The carrying capacity of a container ship is usually expressed in terms of the number of TEUs that can be loaded onto the vessel (one TEU is equivalent to the number of seats a standard container has 20' long, 8' wide, and 8'6" high. container size). The carrying capacity of container ships can range from a few hundred TEUs for feeder vessels to over 10,000TEUs for mother vessels.
People often divide generations of container ships according to their carrying capacity. Up to now container ships can be divided into 6 generations of development as shown below table.
Ship generation

first

Before 1970
second

1970 – 1980
third

fourth
On 3000
1985 – 1995
fifth
On 6000
1995 – 2005
sixth
On 8000
After 2005
The division into such generations is only relative, and often makes sense to evaluate the development of container ship technology and products according to the development length.
It can now be said that the latest container ships belong to the sixth generation (over 8000 TEU). However, from the perspective of transport capacity, the container ships currently in use have a carrying capacity of several hundred TEUs or more. This means that there is still a need to use multiple generations of container ships at the same time, or in other words, the above division mainly shows the difference in the capacity of the ship.

Classification of container ships
1) By development generation: 6 generations (as above)
2) According to the container loading and unloading method: LOLO, RORO, …
3) According to vessel size: Panamax, Post-Panamax, Suezmax, Post-Suezmax, Post Malacamax
4) By level of specialization: general purpose ships, semi-container ships, specialized container ships
5) By operating range: feeder ship, mother ship
World container fleet
The world's dedicated container fleet by the beginning of 2009 has about 4,670 vessels (carrying capacity of 12.2 million TEUs). It is expected to reach 13.7 million TEUs by the end of 2009. Details of the number of vessels by size are shown in the table below.

Vietnam container fleet container
While market transport and the world's container fleet are thriving, Vietnam's container fleet has a very modest number and capacity: with a total of 33 ships, with a total capacity of 20,600 TEUs, all are feeder ships below 2,000 TEUs.
Vietnam container fleet container
Vietnam's container fleet has over 30 ships with a total capacity of over 20,000 TEUs. Shipping capacity is still very modest, compared to other coastal countries.

Try a comparison to see the difference clearly. For example, according to AXS-Alphaliner data, the number of ships owned by OOCL alone has a total capacity of about 204,000 TEUs, which is 10 times the total capacity of the entire Vietnamese container fleet (including over 10 carriers). ship).
The largest container ship in the world
The size and carrying capacity of container ships are constantly increasing, and so the title of largest ship also changes over time. Here are the ships that have been on the list of the largest container ships in the world.

As of January 2009, the container ship MSC Daniela with its announced nominal capacity of 13,800TEU is said to be one of the largest container ships in the world, even, by some, more than its carrying capacity. official Mearsk Lines E-class container ships (11,000 TEU).
However, the issue of determining the nominal capacity of these super-large ships is also a point of contention. It is thought that the carrying capacity of Maersk Lines E-Class ships is actually much larger, possibly up to 13,600TEU (according to CI), even up to 15,212TEU (according to AXS Alphaliner).
This difference is due to the determination of the carrying capacity so as not to affect the visibility from the cockpit. The MSC Daniela has a cockpit located closer to the front, so visibility is less affected, and therefore capacity will also increase. Parameters of the two largest ships today: MSC Daniela and Emma Mearsk in the table below.

Looking from the data in the table above, in terms of tonnage, the MSC (156,301 DWT) is larger than the Emma Maersk (152,800 DWT). However, in terms of size, the Emma ship is clearly larger. In terms of carrying capacity, published data is inconsistent and controversial. Either way, these are the largest container ships available today.
However, Maersk shipping line has also ordered a new generation of container ships with a capacity of up to 18,000 TEU. This series of ships is called Triple-E, and the first ship is expected to be delivered at the end of June 2013.
Meanwhile, in April 2013, China Shipping (CSCL) also ordered 5 ships of 18,000 TEU size at Hyundai shipyard.
And with these super-large ships marks a new development in container shipbuilding technology as well as the world's shipbuilding industry in general.
