They should have rafted up...

OOPS!!! Well at least they did not sink. All they have to do it fish them out and reload them.

Shamoo, is that you down there?

Interesting how 2 went the same way but the third slipped off the other direction. I wonder what caused that?

Physics caused it.

Difficult to get good measurements from the video, but it appears to me the load is not centered on the barge. Perhaps the load was offset to starboard on the front barge.

In the image below, it appears the load is offset to port. With the center of rotation so low on the narrow barge, any list to port greatly exaggerates the imbalance. Once it gets to far, there is no saving it.

From what I have studied in the past is that logs that are transported by loading onto a ship or barge, the transporter is designed to unload that way. That's why one barge tipped one way & the next one the other way. I would cause too many problems for all to unload on one side.

Exactly. This was on purpose. It's how they unload the barges.

Totally different situation...

This is a better video with explanation of the process. Notice the ship/barge is still listing to the dump side after the logs are off loaded.

It is still listing because water is pumped into that side to make it list to unload the logs! It will be corrected after that side is pumped out.
