Now we know what it is and who owns it. One can see on the deck of the submersible ship the two test pilings that they brought with the barge. More than 100m long each!
The world is going to belong to the Chinese in 50years
Aerial view of the piling barge at work for CRBC on the Peljesac Bridge, Croatia:

When this thread popped up, I considered answering “The world’s biggest pile driver?”, but decided against it in case people didn’t get that I was joking. Turns out they actually make them that big. I’d hate to try to sleep in the vicinity of that construction site XD
very interesting to finally see the derrick in its working position…here is a photo of the hydraulic cylinder which lifts the mast which you can see in the aerial photo
now try to imagine the hydraulic pumps and the motors that drive them?
