ACC; AlphaCyanoaCrylate, superglue. If you run the cable into a hole in the deck, a touch of superglue will hold it firmly.
Eyebolt; A bolt, with a ring instead of the usual head, attached to a deck or bulkhead, used for attaching lines, blocks, etc. ( also holds the chains of a swing set )
Where it is the transmission cable for the antennas, it would pass through a stuffing tube. This is a pipe section, welded into the hull to provide through hull passage. It usually has a compression type fitting on the outer end, and once the cable is run through it, the tube is filled with a sealant, and the fitting is set up, or tightened. In the case of a submarine, it would have to withstand a lot of pressure, but at the same time, provide electrical insulation from the hull. I assume that there is a double hull, so the actual stuffing tube would probably be unseen. This I cannot be certain of, as I said before I haven't modeled any submarines....yet.
