Title: Improving engine efficiency of world's largest container ships
Post by: michaeljordan on August 28, 2015, 05:08:39 AM
In maritime industry over the past 60 years, container cargo ships have increased 20,000% in size and while continuing this trend comes with caveats, shippers are looking at increasing capacity even further.In two world's largest container ships  (http://www.ship-technology.com/features/featureturbocharging-the-worlds-largest-container-ships-4627524/)have been fitted with advanced technology turbochargers, so that it helps to reduce their fuel consumption and abide by tightening environmental standards.

I wondered about that neat statistic of 20,000% increase, but it is perfectly good, indeed it's rounded down a little.
The source is here: http://new.abb.com/turbocharging/maritime-cargo-vessels---is-bigger-better

IDEAL X in 1956 had a capacity of 58 x 33ft containers = 96teu
MSC OSCAR taken at 19224teu.
That gives a multiple of 202.35 (ie "over 202 times the size of IDEAL X), which translates to a percentage increaase of 20,135%.

Gents,

Seriously, IDEAL X cannot be considered a containership. It was an oil tanker with a spar deck to transport some containers. She never qualified as a cellular containership, as it was still experimental.

It is like comparing a space shuttle to the Wright Brothers when it comes to space exploration...

At least a purpose-built first generation containership would have been an (easy) target :-) as shown when comparing to AMERICAN LANCER...

Best regards,
Herbert

@ David
my first ship as master, which could carry 30 TEU (8ft high) which would mean that the percentage
is then over 60000 % ?   I think such comparisement is a little off. She was a general cargo ship build
in 1972 and not a container vessel
