This is my experience. ASW units seem to listen passively, then locate using active sonar. I notice that silent running disables torpedo loading, pumps, the snort mast (if you have one); I suspect SH3 sums these things (along with your motor and screw noise) into an emissions total. There appears to be no particular penalty for having the pumps switched off; in AOD you couldn't do this for long periods as you'd start to sink as the bilge filled up.
I tried the scenario again, this time running very slowly and using silent running. I was able to stay in Gibraltar harbour for 24 hrs, with no bother.
Much as I adore GWX I wish the escorts weren't such good listeners, especially early war. You can't go flank underwater within 4km of an escort sometimes. Late-war this is completely understandable (there are many cases of u-boats detected ahead of convoys purely by passive means) but early on during the happy times they could do with some ear plugs.
