They must have put dotted lines on the hull during construction so the cuts could be so accurate.Ed, Mary, & 'Earl'

On a diesel-electric submarine the batteries were changed about every 2 years. They just cut a big hole over the battery compartments, crane the batteries out and new ones in and then put the piece the cut out back in place and spend about a month welding in back in. The Fairbanks Morse diesels were opposed piston so you had a crank at the bottom and one at the top. If the top crankshaft goes not big deal. You just dissasembled the top of the engine and used chain falls to swing back thru 2 or three watertight doors and into the after torpedo room. From there it was set in a torpedo skid and pulled out the torpedo loading hatch and just reverse the process with the new or repaired crank. Now if the bottom crank goes bad then they cut a really big hole in the pressure hull to get it out.
