What does the oil content monitor recirculate back to when the oil content is above 200 ppm?

• A. Oily Waste Holding Tank
• B. OWS
• C. Purifier Bowl
• D. Feed Water Tank

Answer: (A)

The key idea is how the oil content monitor governs where oily water goes based on measured oil concentration. When the monitor detects oil content above the set limit (200 ppm in this case), the stream cannot be discharged overboard. Instead, the system routes it back to the oily waste holding tank, where contaminated water is stored for processing or disposal later. This redirection helps meet pollution-control requirements and prevents releasing high-oil-content water into the sea. The oily water separator (OWS) is the device that normally handles separation and potential overboard discharge, but once the oil content is too high, the flow is diverted to storage rather than discharged. The Purifier Bowl is part of fuel oil purification and isn’t involved in bilge/OCM decisions, and the Feed Water Tank is unrelated to oily-water handling.
