The containership has come a long way in its development since the mid-1950s, with the world’s largest containership – the MSC Oscar – currently reaching a staggering 19,224 TEU.
Ships of this magnitude are expected to continue growing; with recent claims made by shipping giant Maersk Line that, although possible, 25,000-TEU ships are not feasible in the long-term.
According to Trb.org, the first successful containership can be dated back to the mid 1950s, when the ‘Ideal X’ T-2 tanker set sail from Port Newark, New Jersey in April 1956. Although a successful feat, the first basic designs for containerships were not introduced until 1957.
These 1,000-TEU tankers would often carry port cranes, since ports and terminals did not have the equipment necessary to handle shipping containers.
During the 1970s, when the container was becoming ever-more commercialised, the first fully cellular containership (FCC) was constructed, according to Dr Jean-Paul Rodrigue of Hofstra University.
This was a massive advancement compared to previous containership designs, as the FCCs were able to transport containers below deck.
During the 1980s and 1990s, larger ships such as the panamax, post-panamax, and super post-panamax ships had begun construction, as transporters realised that it was more cost-effective per unit to carry more containers in one trip.
Rodrigue has said that there is the possibility of the ‘Malacca Max’ containership that could reach capacities ranging from 27,000-30,000 TEU with a draft of 21 metres, but such a design is not yet feasible with current limitations in port yard space, crane technology and international canals and waterway limitations.
