Maintenance and Reliability Quiz

What is the primary characteristic of Maintenance by Fire?

• It follows a strict maintenance schedule.

• It is performed after equipment failure occurs.

• It uses real-time data to predict failures.

• It minimizes the need for repairs.

Which of the following is a disadvantage of Planned Maintenance?

• It reduces equipment lifespan.

• It leads to unpredictable downtime.

• It may result in unnecessary maintenance.

• It increases the risk of equipment failure.

What is the main objective of Planned Maintenance?

• To allow failures to happen before repairing.

• To ensure maintenance occurs only after breakdowns.

• To perform maintenance tasks at scheduled intervals.

• To avoid maintenance activities altogether.

Why is Maintenance by Fire not recommended for critical ship systems?

• It requires highly skilled personnel.

• It results in higher initial costs.

• It poses an unacceptable risk of failure.

• It follows strict industry regulations.

What is a key advantage of Planned Maintenance over Maintenance by Fire?

• It requires no initial investment.

• It prevents all possible failures.

• It minimizes downtime and improves safety.

• It eliminates the need for spare parts.

Which of the following is a key characteristic of Condition-Based Maintenance (CBM)?

• Maintenance is performed based on a fixed schedule and inspection.

• Maintenance is triggered by real-time data collected from sensors.

• Maintenance is always reactive but also proactive from sensors.

• Maintenance requires no data collection or monitoring from sensors.

What is the primary advantage of using vibration analysis in CBM?

• It detects changes in oil viscosity and level of oil from the level sensor.

• It monitors the electrical currents in machinery and the amperes from the motor.

• It identifies mechanical issues like imbalances and misalignment in machinery.

• It measures temperature changes in engine components including bearings.

How does CBM help improve equipment reliability?

• By replacing equipment before it fails and renew all parts with the spare onboard and also the expenses.

• By focusing only on preventive maintenance and reduce the amount of time for maintenance and repair.

• By detecting potential failures early, allowing for timely repairs and prevent major breakdowns.

• By reducing the frequency of scheduled maintenance and lessen the total cost and expenses of the company.

What is a major challenge when implementing CBM in shipping?

• Integrating CBM technologies with existing shipboard systems.

• Identifying potential mechanical issues from the given data from each sensors.

• Reducing maintenance costs and reduce loss time due to maintenance of equipment.

• Predicting the exact time for repairs and monitor every parts of the equipment.

How does CBM reduce downtime in a maritime environment?

• By scheduling regular maintenance and repair and reduce total cost.

• By identifying and addressing issues before they cause complete failures.

• By using manual inspections and spare parts manual for specific equipment.

• By increasing maintenance intervention frequency and reduce damages.
