In asset management, what is the purpose of an Asset Register?
Answer: Provide a comprehensive record of all assets, their attributes, and location
An asset register is a complete inventory of all assets with their key attributes (location, condition, criticality, value) that underpins all asset management decisions.
A maintenance planner calculates that a critical pump has an availability of 92%. If MTBF is 460 hours, what is the MTTR?
Answer: 40 hours
Availability = MTBF / (MTBF + MTTR), so 0.92 = 460 / (460 + MTTR), giving MTTR = 460 × (1/0.92 − 1) = 40 hours.
Which condition monitoring technique is MOST effective for detecting early-stage bearing defects in rotating machinery?
Answer: High-frequency vibration analysis (HFD/Spike Energy)
High-frequency vibration techniques such as HFD, Spike Energy, or SEE detect the ultrasonic stress waves generated by early bearing defects before detectable heat or visible damage appears.
What is the primary objective of a Criticality Assessment in asset management?
Answer: Rank assets by their potential impact on safety, environment, and production to prioritize resources
Criticality assessment ranks assets by the combined risk (probability × consequence) of failure so maintenance resources can be allocated where they have the most impact.
In RCM, what does 'functional failure' mean?
Answer: The inability of an asset to meet the required performance standard
A functional failure occurs when an asset is unable to fulfill its required function at the required performance level, as defined by the operating context.
Which of the following BEST describes the 'business case' for predictive maintenance over preventive maintenance?
Answer: Predictive maintenance reduces unnecessary part replacement by intervening only when evidence of degradation exists
Predictive maintenance extends component life by replacing parts only when condition data indicates actual degradation, avoiding the over-maintenance inherent in fixed-interval replacement.
The 'bathtub curve' failure rate model shows three distinct phases. Which phase is targeted by burn-in testing?
Answer: Infant mortality phase
Burn-in testing is designed to expose and eliminate early-life failures (infant mortality), ensuring that components shipped to customers have passed through the high-risk initial period.
