Early container ships
In early stages, tankers and bulk vessels modified and
used to transport containers through overseas. The maximum capacity of those
ships was about 1000TEU’s. The first container ship was “Ideal X” and it was it
was the first tanker converted as a container ship in world war 2. Maximum
speed of those type of ships were 18 to 20 knots at that time. After that some
countries begun to build container ships and then second generation of ships
started. Those kinds of ships named as “fully cellular ships”.
In 1980s ship builders realized that when ship become bigger
they can experience economies of scale. With that concept they could transport containers
at lower rate per TEU. The procedure turned into an idealistic circle
exacerbating bigger volumes and lower costs, which fundamentally helped the
dissemination of the compartment. The size furthest reaches of the Panama
Canal, which came to be known as the Panamax standard, was accomplished in 1985
with a limit of around 4,000 TEUs.
Post Panamax 1 and 2
Going past Panamax was a hazard as far as the
arrangement of transportation organizes, extra taking care of framework and
additionally draft confinements at ports. The APL C10 containership class, with
a limit of 4,500 TEUs, was presented in 1988 and was the primary containership
class to sur passed the 32.2 m width farthest point of the Panama Canal.
New Panamax or Neo Panamax
Alludes to ships intended to fit precisely in the
locks of the extended Panama Canal, which opened in June 2016. These boats have
a limit of around 12,500 TEU, however there are a few setups of Neo-Panamax
dispatches as far as length and width. Like its Panamax partners, Neo-Panamax
ships are probably going to characterize a particular ship class ready to
benefit the Americas and the Caribbean, either from Europe or from Asia.
Post Panamax 3 and Triple E
Since 2006, a third era of post Panamax containerships
came to the industry when Maersk shipping line presented a ship class having a
limit in the scope of 11,000 to 14,500 TEUs, the Emma Maersk. They were named
“Post New Panamax” since they are greater than the of the extended
Panama Canal. Current largest container ship is OOCL HONG KONG which has
capacity of 21413 TEUs.
