That reminds me of something which happened where I worked about 15 years ago.Nowadays, in vessels carrying project cargo (big pieces, parts or machinery) it is more and more frequent to weld sea fastening to bulkheads or tanktops to secure them.
We built what can best be described as a temporary control room.
This was basically a shipping container nicely fitted out inside with aircon, a BIG uninteruptable power supply, a computer cabinet, and a special electrical power unit for powering subsea equipment.
This thing was intended to be installed on the back of a supply boat with other equipment and sailed out offshore as and when required.
It was built and tested in the UK and put on a cargo ship to deliver it overseas.
I believe this was welded to the deck to stop it moving around.
So far so good.
But when it was delivered to the customers site it was wrecked!
I don't know if anyone found out exactly what happened, but...
The aircon units were broken off their mountings, the batteries in the UPS were scattered all over the insides of their cabinet, the hinges of the swing frame in the computer cabinet were broken, the PLC modules were all out of their card cage and dangling on their I/O cables.
Outside, the lifting eyes were stretched and there was an impression of the crane hook in the centre of the roof!
Maybe they forgot to grind off the seafastening welds and just gave it a pull with a BIG crane.
