The correct wording should be 4,679 containers. This includes 40’ FEU and 20’ TEU.
Upon reflection though , one must be very careful reading the data given in the news joints and even from other sources, which should know what they are talking about. I will give an example which I have nicknamed “Emma Maersk stupidity syndrome”.
And believe it or not there are folks in the management offices who either do not know the difference or do not understand it. Below is a screen shot from Wiki.
You will see two versions and they say " depending on definition" . Ship planners are interested in both figures . The lower one 11000 teu tells you how many 20 ft containers of 14 tons the vessel can accomodate and be on the Plimsol mark . Such load is called homogeneous load. Planners ask me" how many 14 tons homo can you take??" .
Then my obvious answer is " be so kind and have a look at the “effing” vessel description , what is an inalienable part of every " time charter party" and planner should have a copy and know it by heart."
In the stability booklet one may find other homo loads ( 10 ,12, etc ,etc) .but 14 T homo is the one which will always interest new Charterer when you switch time charter from MSC to Maersk for example.
The higher figure in case of Emma is the nominal intake meaning You have 14770 slots on the ship to accomodate 20ft containers and this figure one may check looking at the emty stowage plans .
Hence judging the vessel size by TEU figures may be misleading, better look at LOA, B, and Tmax ( draft at summer load line) . Cheers.
Addendum : below is part of M/V Dali description
One can see clearly what I was earlier talking about . Another tricky question is about reefers. In this table the authors made a fundamental blunder declaring the number of reefers the vessel can take. Never , ever make such declaration that you can load 1400 reefers. Declare only 1400 refer plugs. But this is off topic , hence I will stop .
