Not really metal working in the video, but products of metal working
in the form of stacked Conex boxes and the ship hull undergoing some
severe strain testing in rough seas.

In conditions like that, you'd better hope some of those boxes don't
let loose and unbalance the load.

I am not completely familiar with how these boxes lock together when
stacked on the ship.

Do they just stack them up like Legos, where the bottom box locks to
the deck and the next box locks to the top of the lower box and so
forth? So, the strength of the entire stack is dependent on the
strength of the lock down of the lowermost box?

If so, the strain on the lowermost box in seas like this must be
incredible.

Have look at this site. The Rena has been aground for about a month now
off New Zealand.
http://www.nzherald.co.nz/nz/news/ar...ectid=10763217

These are full size Sea containers 40 feet long and 8 feet wide about,
not the weenie Conex containers you may have encountered in Military
sevice.

This is how they are locked together.

The lock on the hull is similar but works from the side.
Plus they usually lock every other row together with a device that looks
like a bar clamp with hooh pade.

That is a tough go condition.

I wonder if a crane tower could be attached to the high side hull
and the boom have a lifting bar attached to the stack on the far side.

The tower could winch up the boxes and slide weights outward on the
tower that is now becoming parallel to the water - starting out 45 degrees.

Just a thought - and I'd hate to pay the overtime, hazard time and
insurance on the crane - but then the boxes might pay for that in a
handshake.

The Govmint and the Conservation movement are very concerned about the
pollution of a National Park ( just a description) type beach.

Some people who left Christchurch after the earthquake have their
lifetimes possesions in containers out there on that boat.

I guess I thought Conex was just a generic term for that type of
container and didn't realize a Sea container and a Conex box were two
different items.

Great new information to me. I always wondered about how this was
accomplished but never really investigated it. The forces on those
components must become massive in rolling seas like those in the
video. Any defect in their manufacture could lead to serious problems
at sea.

The key to making container ships viable was the locking system,
invented in the 1960s. The inventor of that system just recently died.
