🔍 Key Concepts

• Understand the purpose of a predictive maintenance program versus routine monitoring • Difference between snapshot data (one moment in time) and trend/comparative data (changes over time) • What vibration analysis and lube oil analysis are actually used for on ships

💭 Think About

• Ask yourself: If readings are taken monthly, are they meant to show only what is happening at that single moment, or how things are changing over time? • Think about how engineers use a series of vibration and oil analysis reports: do they mainly compare today’s data with earlier results, or do they wait for one test to tell them something will fail immediately? • Consider what kind of information is most useful for planning repairs and avoiding unexpected breakdowns: one-time measurements, trends, or guaranteed prediction of the exact failure time?

✅ Before You Answer

• Check which option best matches the idea of trending data over time rather than just a one-time reading • Verify which choices sound too absolute or certain (e.g., “definite,” “immediate,” or guaranteeing exact prediction of failure) and be cautious of those on exams • Confirm which answer reflects that vibration and oil analysis are mainly used to compare current condition to past condition to judge whether machinery is getting better or worse
