LWAMI would definately help a bit because of the increased aft baffle for surface active sonars... so theoretically as long as you were able to stay behind any ship that was close enough to detect you without being picked up on TA you would have a chance, in which case I would look at setting the acoustic conditions to mud or sand bottom and the sea state reasonably high with a bottom limited environment and you might have a decent chance if the port is large enough.
