Red pipe markings indicate which system?

Explanation:
Red pipe markings designate the Fire Main—the ship’s pressurized seawater system used for firefighting. This network runs throughout the vessel to supply water to hoses, monitors, and sprinklers, so responders can act quickly in an emergency. The color red is reserved for firefighting water lines to keep them distinguishable from other piping, such as fuel or foam systems, which use different colors to avoid confusion during a crisis. So when you see red, you’re looking at the main source of water for firefighting on the ship.
