Yellow thing

Discovered this thing in unit 3.
Fresh painted, the yellow color indicates it must part of the fuelgas system but we don't know where it has to be placed.
Maybe in the new gas skid at unit 6?
We'll see...

Saw this on a crate in unit 3 also.
This is a sticker that's very important: it indicates if the crate has been exposed to shocks or was tilted.
It houses the new gasturbine control system (Speedtronic) for unit 6.
So maybe the yellow thing and the contents of the crate match somewhere.
