Back in the Dark Ages when all Navy Ships were powered by mighty steam (or the 80s, take your pick) I was given a good sized job on the USS Paul, FF-1080. It was to install a new run from the towed array room all the way to Sonar in the 0-2. There was already one in place but this one had to be run differently: a specific distance from any other existing line carrying electrical current. It was a pretty complex job and had me working directly with a NAVSEA SUPSHIP to make on the spot changes to the drawing as needed. I first had to modify a ton of hangar to wire ways to the two lines would be the correct minimum distance from the existing (I had two guys who did that for me) and then all the bulkhead penetrations, aka, stuffing tubes. We decided (I was told) to drill all the holes with hole saws so we didn’t have to worry about a lot of hot sparks from burning in tight quarters. We still had to weld them but it was a lot less hot work
I would concur with the Chief's assessment.
