That's like something the russians would make, except it works and hasn't
sunk yet.

The barge crane is lifting the barge crane!

Must be pretty iffy to lift stuff with a vessel mounted crane, a lot
of tipover possibilities. No way to extend support feet!

But there's an unlimited supply of pumpable ballast available.

*This* is a couple of big marine cranes. Not really a fair comparison
since it's a floating drydock rather than a barge, but it did travel
here from China. It's passing my favorite surfing spot in the first
two pics. The destroyer in the last pic is 500 feet long.
