Development of Container Ships Container ships are usually defined in terms of TEU or twenty foot equivalent units. An 8500 TEU for example can transport 8500. twenty foot equivalent units of containers between two ports. With time being a critical factor for most globalized operations and fuel costs increasing by the day it has become inevitable for the shipping owners to transport maximum number of containers possible in one single voyage. This has lead to a continuous research and study into the development of new designs of increased capacity that would be capable of withstanding the rigours at sea. At the time, it should also be able to navigate easily through different canals and seas offering varying degrees of drafts. (Container Ship Types, 2000) Source: 4250 TEU Container ship, (Container Ship Focus, June 2006) Technical Requirements Purchasing of 18000 TEU ships is a matter of great achievement for any company and it is said that only Maersk which is the leader in Container ship transportation have ventured into buying 10 number of ships from Daewoo. The increased container capacity poses lot of technical queries, which need to be taken care of. 1. To account for the increased number of containers the length and width of the ship would be needed to be increased proportionately. This increase would again pose problems to the ships manovereability. It is known that ships have to navigate through various canals that exist between high seas to cross across continents. The PanaMax of size 4100 TEU’s delivered in 1980 was the largest to be delivered in those times and was named by its ability to pass through the Panama Canal. There was however no major change in the next twelve years and the size hovered around 4500-5500 TEU’s. Ships of length 294.1m, width 32.3m and draft of 12m was the maximum dimension of a ship capable of passing the Panama Canal. An accident leading to the slippage of 4 containers containing lethal arsenic oxide into the sea in 1992 near New Jersey lead to the International Maritime Organization (IMO) adopting the guidelines on safe securing of cargoes and became part of the International Convention for Safety of life at sea, 1974. (SOLAS) This required the ship must have a Cargo securing manual approved by the Flag State.( Container Ship Types, 2000) Most container ships built thereafter were an offshoot of the PanaMax category with increased TEU. The Post-PanaMax built in 1996 had a capacity of 6400TEU. By 1999 this size had increased to 9000 TEU’s. These ships have cell guides which enable better arrangement of container cargo above deck. However five cargo holds were unprotected from rain and rough seas which made it very critical to have an efficient bilge or waste water disposal system. The Suez-Max Large container ships (ULCS) built thereafter were capable of carrying 12000 TEU’s. The Post-Suez-Max ships are classified as those ships which can carry capacities upto 18000 TEU. This would require a ship breadth of 60m with a maximum draft of 21m. The Suez Canal is being revamped to accommodate these increased sizes of ships in the current years. Ships of 18000TEU are classified as Malacca Max since the Malacca strait offers a draft of 21m. The harbours of Singapore and Rotterdam are the other ports that offer such drafts.
