Question 1 of 27070

The duty engineer reports an alarm on the condensate observation tank oil sensor. Which of the following could be a possible cause?

🔍 Key Concepts

• Condensate observation tank location in the system and what normally drains to it • How oil can get into the condensate/steam system • Which coolers or heaters use steam heating or jacket water that could mix with condensate

💭 Think About

• For each option, ask: does this piece of equipment have a path where oil could leak into the condensate or feedwater system? • Which of these components is most directly connected to the steam/condensate or jacket water side, rather than the seawater side? • Think about which fluids are separated by each heat exchanger and what happens if a tube leaks.

✅ Before You Answer

• Verify which equipment is heated by steam or jacket water that later returns as condensate. • Check which of the listed coolers/heaters contains oil on one side and water/steam on the other. • Eliminate any options where a leak would more likely put oil into seawater or fuel, not into condensate.
