I am new to this group, even though I served  on board, I was in the engine room as an MM2 under the tutelage of a guy by the name of Francis D. Kuhn, MM1 . He was a likeable fellow, however he very often pushed my buttons, making me draw out and learn all the major systems (steam, condensate, vacuum, lube oil,etc) in the engine room. If I made a mistake. he would tear up my drawing and tell me to do it again until I got it right. . Needless to say, I learned all the viable systems necessary to make the "Dirty D" operational. I also had to learn how to light off and shut down the plant by myself.  Kuhn died after we returned home early, from one of our Med cruises. I know he was preparing me to take charge of the engine room after his death. He sure was relentless in my training, but a hell of a nice guy otherwise. I was one of the pallbearers at his funeral. But that's another story

 I later made MM1, and was placed in charge of the refrigeration plant. I seem to remember the electric shop was just above the reefer plant. (I may be wrong about that. my mind is getting a little fuzzy these days).

If I remember correctly, the reefer plant contained 13 Carrier 5H80 cargo refrigeration compressors with automatic unloaders, which could be cross-connected to almost any refrigerated cargo hold.

I had the reefer crew polish the refrigerant receivers and copper control lines on the compressors so they would sparkle when the Chief Engineer conducted the occasional field day inspection.

 I also remember installing a rack (bed) on the bulkhead in the reefer plant and sleeping there rather than in crews quarters. It finally met with opposition and I stopped using it.

I really loved duty on that ship. It was like family.
