Question 55General Subjects - QMED

The correct answer is B) clean water flushing line. The line labeled "C" in the illustration GS-0175 would be identified as the clean water flushing line. This line is used to flush out the oily bilge water system, removing any remaining oil or contaminants before discharging the water overboard. The other answer choices are incorrect because: A) The oil discharge line is typically labeled differently and is used to directly discharge oil or oily waste overboard. C) The oily bilge water inlet line would be used to collect the oily bilge water, not flush the system. D) The tank drain line is used to drain liquid from a storage tank, not the bilge water system.
