> That chopper has a max payload of 32000 lbs and a 40ft TEU has a max gross weight of 67500 lbs. Maybe you get lucky... but you'd need a lot of luck.
1. This assumes that the containers are actually loaded to their maximum gross weight. That doesn't seem likely; you're much more likely to run out of volume first - even if you're deliberately "optimizing" for as much weight in those containers as possible.
1a. This assumes that the heavy containers are at the top rather than the bottom, which would be backwards from how containers are supposed to be stacked (or even allowed to be stacked per your average safety guidelines around center of mass, stack limits, etc.).
2. This assumes that multiple helicopters can't work in tandem (which they can, from what I understand).
So yeah, even if there are some containers that are too heavy to safely unload via helicopter, I strongly suspect that quite a few - most, probably - of those containers could be readily unloaded. And further, even if that ain't enough to get the ship moving again, it's at least a good start.

There was a sea basing study and that only looked at 20ft containers and dismissed even a theoretical upgraded CH-53X (although of course the study was looking at much longer range than just lifting it and putting it back down) but again, that was just 20ft, these 40ft ones are just too heavy for choppers.

For many containers, using helicopters would probably mean at least partially unloading their cargo, which is a difficult and time-consuming endeavor. The process of removing containers by helicopters would be even more difficult, dangerous, and time-consuming, so it is very, very unlikely we will see it implemented unless the situation gets really desperate.

Even better.
