thanks for sharing this with us Rick as I find this very interesting,
Back in 2008 when STX first came up with the concept for a 22,000TEU ship it was envisaged that it would have to be 460m in length with a beam of 60m.
As always the ships designers have found ways to add ever more capacity into the standard 400 x 58m profile. When the first series of Triple E vessels were launched in 2013 I was told by a very reliable source that the second batch 10 vessels from Mayview onward had slightly more capacity due to slight design changes, which perhaps explains why their quoted capacity changed from the initial 18,270 to 18,340TEU.
If this is indeed correct and setting aside any issues that extra length or container height would give the master, planners, ports etc, these ships would not need to be 460m in length. With the arrival of MOL Triumph we now have ships that can load 12 tiers under deck.
The designers would have to weigh up the pros and cons of either loading a 12th tier on deck behind the bridge or increasing the overall length by adding an additional 40' bay both of which would easily increase capacity to just beyond 22,000TEU.
As we have already seen with container ship design perhaps it
