Ok, so now that we have a color rendition of the piping color coding, the next question is, exactly how were the pipes marked? Was it at a general interval along each pipe, in groupings in specific areas of a compartment or just in areas where it was just visually convenient? I'm especially curious about the areas under the deck plating where you would think you would want quite a bit of identification when you're crawling around in relative darkness while being depth charged.
