Hey Bullzi, ask your friend where this was at. I saw the same picture on a Facebook post in the Navy Electricians Mates group (yes I am a proud member of that group). From the looks of the wires it appears to be residential (the wires at the top look like they are Romex) and none of us could definitely say the source of this. I have seen some serious safety no-nos in berthing areas on a ship, especially from aviation electricians who did not understand that planes are not wired the same as a ship or a building. Since Ive been out I have seen some questionable workmanship, but never anything as bad as your picture.
