They could just be doing repairs to the barge. It looks like they're lifting things in/out of the hull, and there's a load of gas canisters on the deck for welding. The yellow floating things will be where the anchors have been dropped as a backup to the spuds (the big pole things anchoring the barge to the river floor).

It's the cleanest it has been since the Tudor times as well!

Dredging of some description would be my guess.
