Good question. I know that some ships run their propulsion motors on 17KV AC;
I'm not sure of the frequency, or if it's 1-phase or 3-phase. The Chief Engineer
of the Carnival Triumph and I spent about 15 minutes discussing the power chain
between the diesels and the screw(s) on that ship, and I learned a number of
interesting things. This conversation led me to trawl through the UK marine
accident investigation agency pages, where there are some interesting reports on
failures in the electrical segment of some ship propulsion systems.

I also wouldn't be surprised if some steel mills ran very high power motors on
high voltage AC, but I don't have direct knowledge of that.
