🔍 Key Concepts

• Steam cycle condensate and feedwater system operation, especially the function of the main condenser and deaerating heater • Consequences of abnormal levels in tanks that handle sewage, lube oil, and condensate/feedwater • Which condition could most directly and immediately affect boiler/feedwater quality and turbine protection

💭 Think About

• Which listed condition, if not corrected quickly, could most directly lead to carryover of water into equipment or loss of vacuum/contamination in the steam cycle? • Compare the safety and operational impact: which condition could cause serious damage to the boiler or turbine versus which ones mainly create maintenance, environmental, or housekeeping issues? • Think about which system must be kept within a very narrow operating range during watchstanding, and which systems can tolerate short-term deviations without immediate damage.

✅ Before You Answer

• For each option, identify whether the effect is mainly operational/safety critical or environmental/housekeeping • Verify which components (condenser, lube oil storage, sewage chlorination, deaerating heater) are part of the primary steam/water cycle • Ask: which condition, if left unattended even briefly, could result in equipment damage or loss of propulsion, not just an alarm or required report.
