Do Container Ships have containers that lock vertically as well as horizontally?
Searching for container ship accidents.
Most seem to lock vertically.
If they locked vertically as well as horizontally maybe there would be less containers floating in the ocean ?
clearly it has never been wise to stack things high on ship. Sure many trips may go OK but the first time one doesn’t who has the egg on their face?

They look like cardboard models.

They do don’t they
They lock vertically and never lock horizontally.
Would it make sense to brace horizontally as well? Or perhaps losing a few containers overboard is preferable to the whole ship heading for the bottom of the ocean. The one which would be better would depend on rolling stability (distance between centre of gravity and metacentre).

Do they or could you have smart ships that can load/off load water to stabilise loads automatically (within reason a storm might be a lot harder)

Ship stability is a science in itself, and involves a lot of physics and engineering.
This might help to understand container stowage:
http://www.containerhandbuch.de/chb_e/stra/index.html?/chb_e/stra/stra_01_03_02.html
Down below the deck level the holds have vertical guide rails that lock the containers horizontally.
Those that are stacked on decked are locked vertically by special clamps. The bottom two or three tiers are lashed down the the deck with steel rods and turnbuckles. The lashings don’t go all the way up. It is hard to lock all the containers horizontally because there are two standard heights for containers – standard 8’6” and high cube 9’6”. If these get mixed on a stack the locking points don’t match up. The loading plan is highly technical and is a specialised occupation, it seems that adding in another layer of complexity in sorting stacks by height is not normal practice.

Surely someone can come up with a better vertical and horizontal interlocking system.
What about using strong magnets ?

Nothing can be built infinitely strong.

Couple of occy straps should do it!

it might sting a bit if a crew member got hit when one goes ping.

They banned them at supermarkets when a trolley boy was killed when it pinged him in the throat

Is that a ‘true legend’? Like the one about the bloke who was cut in half when an overloaded nylon mooring line snapped in half and recoiled?
Everyone ‘knows’ it’s true, but details are a bit scarce.

Protect children during school holidays: Minister
July 1996
A 13 year old shopping trolley collector died when an elasticised “occy strap”, used to keep the trolleys together, detached from the trolleys and struck him in the throat.

Ok, pay that one.
Hopefully they got them on child-labour laws as well as OH&S.

Didn’t the mythbusters do the sliced in half by a cable thing?

I do vaguely remember a news article about it but yes it was many years ago

In the past and probably still. If there is industrial action at ports around the world and ships can’t offload their cargo , where they need to go to another port to load up and keep the chain going , ships have pushed containers into the ocean.
This just popped up in my youtube suggestions.

How they unload these toppled over containers. Not for the faint-hearted, nor for delicate cargo…
