Question 1 of 27070

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?

🔍 Key Concepts

• ALCAP purifier operation – how automatic water discharge is controlled based on water content in the separated fuel • Location and purpose of water transducers/sensors in centrifugal purifiers (dirty side vs. clean side) • What it means when there is excessive water in the service tank instead of being discharged overboard

💭 Think About

• Think about where you most need to detect water if your goal is to protect the service tank from water carry‑over. • Which sensor or component directly influences whether the purifier keeps water in the bowl and discharges it, versus letting it pass along with the fuel? • Consider whether bowl RPM problems or solenoid valves would more likely stop separation entirely, or specifically cause water to pass into the clean oil outlet.

✅ Before You Answer

• Verify which side of the purifier (dirty oil inlet vs. clean oil outlet) is monitored to decide when to dump separated water. • Confirm how ALCAP systems detect water in the clean oil to trigger either an alarm, discharge, or recirculation. • Eliminate components that would mainly affect mechanical separation speed (like RPM) rather than water detection and discharge control.
