Question 114Motor Plants - 1st Asst/Chief70% to pass
Your ship is equipped with ALCAP heavy fuel oil purifiers. The watchstander reports excessive water drained from the fuel oil service tank. Which component should he check?
AI Explanation
The correct answer is C) The water transducer located in the clean oil discharge line.
When a fuel oil purifier is removing excessive water from the fuel oil service tank, the issue is likely related to the water removal system of the purifier. The water transducer in the clean oil discharge line is responsible for monitoring the water content of the purified fuel oil. If this transducer detects high water levels, it will trigger the purifier to remove more water, which could result in excessive water being drained from the service tank.
The other options are incorrect because: A) The dirty oil supply line transducer would not be directly responsible for monitoring water content in the clean oil discharge. B) The bowl RPM does not directly control water removal. D) The fresh water line solenoid valve would not impact the water content of the fuel oil.
