Reference Answer
The oil monitoring system for bilge and tanker ballast discharges ensures that the oil content in discharged water complies with regulatory standards. Below is a description of its general arrangement:
Water from the discharge line is sampled before reaching the overboard discharge valve.
The sample is directed to the PPM monitor, which measures the oil content in parts per million (PPM).
The oil content value from the PPM monitor is sent to a comparator, which compares it to a preset allowable limit.
