Maintenance PQ2

A ship’s main engine has suddenly stopped working due to a broken fuel injector. The crew must replace the injector to restore functionality. What type of maintenance is being applied?

• Preventive Maintenance

• Corrective Maintenance

• Predictive Maintenance

• Proactive Maintenance

During a routine inspection, the ship’s engineer finds minor cracks on a pump belt and replaces it before it fails. This is an example of:

• Predictive Maintenance

• Preventive Maintenance

• Corrective Maintenance

• Emergency Maintenance

The crew uses vibration analysis to detect misalignment in a rotating shaft and schedules a repair before a failure occurs. This is an example of:

• Preventive Maintenance

• Reactive Maintenance

• Predictive Maintenance

• Corrective Maintenance

A ship's generator is maintained according to a fixed schedule, where oil changes and filter replacements occur every 500 running hours. This is an example of:

• Corrective Maintenance

• Predictive Maintenance

• Preventive Maintenance

• Condition-Based Maintenance

The chief engineer receives an alert from a remote monitoring system showing abnormal temperature readings in the ship’s auxiliary engine. What maintenance approach should be taken?

• Ignore the alert and continue operations

• Schedule maintenance only if the engine completely fails

• Use predictive maintenance to inspect and address the issue before failure

• Wait for routine preventive maintenance to check the problem

The ship’s steering gear suddenly fails while maneuvering in port, requiring immediate repair. What type of maintenance is being carried out?

• Preventive Maintenance

• Predictive Maintenance

• Corrective Maintenance

• Planned Maintenance

Which of the following maintenance strategies can help reduce unnecessary maintenance costs by relying on real-time equipment data?

• Preventive Maintenance

• Corrective Maintenance

• Predictive Maintenance

• Reactive Maintenance

A shipowner wants to minimize unexpected breakdowns and maximize the efficiency of onboard equipment. Which combination of maintenance strategies is most effective?

• Rely only on corrective maintenance

• Use preventive and corrective maintenance together

• Use preventive and predictive maintenance together

• Avoid maintenance until a failure occurs

Which of the following is a major disadvantage of corrective maintenance?

• It prevents failures before they happen

• It increases safety and reduces operational costs

• It leads to unexpected downtime and expensive repairs

• It allows for better planning and scheduling of repairs
