Question ID: 468554
The total Container (TEU) carrying capacity in a Container Ship,
perhaps has direct relationship with the ?dead weight? of the Ship.
1)	If so, what may be the ?average weight of a single loaded 20ft
Container? in a Container Ship for a given TEU carrying capacity, say
1000 TEUs ?
Please advise.
2)	In case the average gross weight of a loaded TEU is 14 mt, and all
the loaded TEUs are of 28 mt each, will the number of TEUs boarding
the ship be reduced on prorate basis, say 1000 TEUs Container Ship
will carry only 500 TEUs ? If it is correct, 50% of the space in the
ship will remain unutilized. Please clarify.
3)	Is it correct to assume that handling of 50% of Container capacity,
will consume only 50% of the normal time needed for the ship at both
the loading and unloading ports, and thus enable quick turn around.

Eagerly looking for your guidance.

There is no answer at this time.

1) 'dead weight' / 1000   ( I'm not happy with the term dead weight )


The 10,000-ton figure refers to the weight of Fort Crevier as measured
in Dead Weight Tonnage (DWT) -- the amount of cargo, fuels, water,
stores and crew that she could carry when fully loaded. Dead Weight
Tonnage is expressed in long tons of 2,240 pounds each.

2) Yes 50% of the TEU will be unused 
   if one exceeds the 'dead weight' by 100% the ship will sink

3) No it will not be 50% of the turnround time
   - 'deck cargo' is easier to get at than containers deep in the vessel
   - turnround time is not purely down to loading and unloading
   - in the real world there is queueing, refuelling, bureaucracy

Having said that, it is quite an interesting point, from a practical
point of view if you can 'double stuff' your containers from 14mt to
28mt then who cares if the vessel is carrying some air ?

There might be other factors, such as weight considerations for land
shipment of the containers to and from the container terminal.

It would be intriguing to know what you are looking into.

1.(a) Thank you for your prompt response. Noted the definition of the
term DWT. Our object in referring to ?Dead Weight? (DWT) is only to
link with a parameter to the ?total permissible gross weight of
specified containers? (TEUs) carrying capacity? in a ship. Hence, we
request you to guide us as to the correct nomenclature / terminology /
expression, instead of DWT, to indicate the ?total weight of fully
loaded TEUs? in a given ship.
(b)   Is the total gross (cargo + Tare)  weight of loaded TEUs in a
ship is standardized ?. OR

        It may differ from ship to ship depending on the overall
configuration of the ship?

(c)   Our specific object is to know what is the ?overall gross weight
of ONE TEU? in a ship, whether by standardization or by practice.

2.      In the penultimate Para of your reply you mentioned about
?weight considerations for land shipment of the containers to and from
the container terminal?. It is an interesting aspect of logistics. Is
there any constraint on ?gross weight of a TEU? during multimodal
transportation? Kindly clarify.

Thanks and Regards.

I am not qualified to even comment on many of your questions

However, please also bear in mind 'load distribution' 
If I were stuffing a ship I would have the heavy stuff at the bottom.
Never an equal distribution of weight from top to bottom.

Your question intrigued me as a result of a conversation (a long time
ago) with a friend of mine who once had a software house writing 'ship
stuffing' systems.

Most of your questions could be answered by physically walking around
a container port - and talking to the Master of a container ship.
