When discharging clean ballast, prior to entering the loading port, if the ballast is determined by the oil monitor to exceed 15 parts per million of oil, the deballasting must _______________.
AI Explanation
The correct answer is A) be terminated automatically.
This is because the International Convention for the Prevention of Pollution from Ships (MARPOL) regulations require that when the oil content of the ballast water exceeds 15 parts per million, the discharge of the ballast must be stopped automatically. The oil monitor is designed to detect when the oil content exceeds this limit, and it must trigger an automatic shutdown of the deballasting process to prevent the discharge of oily water into the port's waters.
The other options are incorrect because B) completely discharging the ballast is not required, C) allowing the oil to settle out and then resuming at a slower rate does not meet the automatic shutdown requirement, and D) completing the deballasting after "load on top" is not the appropriate procedure for dealing with oily ballast water.
