The duty engineer reports an alarm on the condensate observation tank oil sensor. Which of the following could be a possible cause?
AI Explanation
The correct answer is D) A leaking bunker tank heating coils.
The condensate observation tank is designed to collect any oil or other contaminants that may leak from the bunker tank heating coils. If there is an alarm on the oil sensor, it indicates that oil is being detected in the condensate tank, which is likely due to a leak in the bunker tank heating coils.
The other options are incorrect because a leaking main engine lube oil cooler, hot water heater, or fuel cooler would not directly cause oil to be detected in the condensate observation tank. Those types of leaks would likely be detected elsewhere in the system.
