Bob I have been to all of those places, we also worked on any type of steam driven equipment, such as bilge turbines, compressors etc. Also worked on the Gulf Stream in the bay, which at the time was the sister ship to the Valdez (sp?) quite an ominous site to pull up next to her on a tug and scramble up a ladder and over the side! I've been on sea trials on the Dale (FFG) and the Serrabachi munitions supply ship, forget the designation. I was on one of the carriers and me and another guy were carrying a toolbox, we were way down inside and lost all of the lighting in the ship, everything just stops until its lit up again due to the fact many deck plates are removed as you probably are aware. Very dark in there when that happens!
Oddly also, my company worked at a Naval jet engine facility near the Scudder Falls Bridge in PA, the name and exact location escape me now, but they tested jet engines outside the air frame there. The testing included 2 buildings we were primarily involved in, one was a 2 story building with about 8 huge air pumps and ducting that went to the 2nd building, a quonset hut where the engine testing was done. The air pumps would simulate altitude in the building while running the engine!
