On a recent week, the Kodiak paper had 3 articles about big , 60 to 150 feet, boats from Kodiak stranded by the weather. That's what happens in rough winter storms: 20 foot seas batter you around.
This barge lost it's tether to the hauling tug. Adrift it went till calm weather allowed a recovery.
Incidentally, when we moved here we asked about getting insurance on our container which would be travelling form Seattle. They pointed out that they are stacked 3 containers tall; and a car may be placed on top of that. Occasionally a container falls off the barge. When we asked if they stopped to recover the container, we got a real peculiar look.
We bought the full insurance.
