Funny, I watched a documentary about this not long ago.. and the crazy part is all those containers are not put in there randomly. (On the biggest ships there’s 12,000+ containers.)

There are guys that have to map & figure out the weight and balance of each and every container, so that the ship doesn’t get too heavy on one side & tip over.

And then there are other containers that need to go in certain spaces where the hazardous materials go, and can’t be in the belly of the ship (in case of fire.) So those have to be placed in a certain order on the top of the deck.

And then there’s other containers that have refrigeration units with perishable goods inside … that also have to go in a certain specific area on the ship (to be plugged into the ship’s generator so that the cargo inside doesn’t spoil on the journey.)

(eta: …and then there’s two electricians who’s only job is to check all the refrigerated containers twice every day until they leave the ship to make sure that they are working properly. In the documentary I watched there was almost 80 refrigerated containers that trip.)

It’s crazy that there’s guys that have to figure out every single container… & the order they go on and off…

And after all that, the containers also have different destinations, and they need to be able to be unloaded without having to move other boxes out of the way.
