Question 73Safety & Environmental - 1st Asst/Chief

The correct answer is D) High capacity fan. The high capacity fan is used to supply inert gas from a flue gas system to the cargo tanks. This system uses the exhaust gas from the ship's engines or boilers as the source of inert gas. The high capacity fan draws the exhaust gas and delivers it to the cargo tanks, creating a positive pressure and displacing the oxygen to prevent the risk of explosion. The other options are incorrect because: A) An inert gas compressor is used to compress the inert gas, not to supply it to the cargo tanks. B) Exhaust gas pressure alone is not sufficient to deliver the inert gas to the cargo tanks, and C) Natural aspiration would not provide the necessary volume and pressure to effectively inert the cargo tanks.
