Yeah, you'd think you'd have shipping insurance.... Must have been pretty violent sees to snap the tie down cables Jeff, with a container, what makes it safer? Will you just strap the car down better?
Stuff is safer, in that no one is just walking around it when ever they wish...not going to get dirty or marked, and yes..I tie stuff down in the containers as well. (normally RORO stuff would be too obviously..) once I load the container, a seal gets put on the door and the only way it will be opened is by Customs if they want to check it. With RORO, the vehicles are sitting down at the port just in a parking lot until they get loaded..and people around them while on the ship too.
I heard of a guy who sent a motorhome RORO years ago, and when it got to Oz, there was greasy boot prints on the carpet inside, all over the place..obviously dock workers having a look around... (I did send a 5th wheel camper roro once, but locked it before dropping it off..and that was just because the buyer wanted to go that way instead of flat racking it...)
And yes, containers do fall off...and yes they will float for a time. Where I used to load containers years ago..one of the owners had a mate who worked for the coast guard on a ship that had a huge harpoon sorta gun that was made just for sinking containers (they patrolled the port of LA and Long Beach area)
That said...in all the years I have done this, I've never had a container fall off a ship,, (or known anyone personally who had it happen either)
they would float for a little bit, but most containers Ive used/packed (again, while transport coordinator for a container fork company) sealed reasonably well, but not enough to keep air and water out if they were submerged.
Correct..the containers have air holes...believe they have to, to be able to breathe and equalize pressure inside with the large variance in temperatures they encounter...going over the equator, etc.
