Could Russia operate shipyards in occupied German territory?

Could Imperial Russia reliably operate captured German shipyards in occupied territory?

It would try, but Russification, sabotage, population flight, and armed resistance could prevent the captured yards from becoming usable capacity.

A chat challenge asks whether shipyards in occupied German territory could function without expelling the local population or suffering sabotage. The Russian leadership might try precisely because it would define the annexed coast as Russian territory. The regime's expected response would be Russification rather than a restrained effort to retain local consent and expertise. That policy could drive population flight or provoke a civil war among people who had recent military experience in the German Army. Capturing industrial plant therefore does not automatically deliver the skilled and politically stable workforce needed to use it.
