The ship didn't capsize. In fact if it were in the water in this orientation it would only be listing. Since it is in dry dock, it looks like it merely fell off the cribbing/supports on one side, or maybe they collapsed. Going to be a handful to get it back upright and repair any damage.
If the writer had a bigger cap size, might have figured that out. ;^)
Yep, she's off the cradles. Normally when that happens one option is fill the well and let the ship right itself. If it ends up in a 45 degree list with people dangling off the handrails, it's possible that something isn't quite right...just guessing on that part...
