Fixing problems only when they arise

Scheduling regular inspections and servicing

Replacing parts before they wear out completely

Rebuilding the engine after extensive use

Fuel consumption logs

Spare parts inventory

Maintenance performed and dates

All of the above

They are ignored in favour of experience-based practices.

They provide a baseline for service intervals and procedures.

Oil changes and filter replacements

Visual inspection for leaks and damage

Testing and adjusting fluid levels

All of the above

It identifies the brand of oil currently in use.

It helps detect potential engine problems through wear particles.

It determines the remaining lifespan of the oil filter.

It is only necessary for very large commercial vessels.

Prevents overheating and potential engine damage.

Improves fuel efficiency and reduces emissions.

Extends the lifespan of engine belts and hoses.

All of the above

Always work alone to avoid distractions.

Wear appropriate personal protective equipment (PPE).

Bypass safety interlocks to expedite repairs.

Anyone with mechanical experience can perform basic maintenance.

Proper training ensures technicians understand specific engine models.

Training focuses solely on safety procedures and not technical skills.

On-the-job experience replaces the need for formal training.

Ordering parts only when needed, regardless of lead times.

Maintaining a readily available stock of essential spare parts.

Using non-genuine parts to save on maintenance costs.

Replacing all parts at once, even if they are still functional.

Minor performance issues that can be ignored.

Increased risk of engine breakdowns at sea.

Higher fuel consumption and operating costs.

All of the above

Engine model, operating hours, and environmental conditions

Age of the vessel and captain's preferences only

Availability of spare parts and repair personnel

Frequency of long-distance voyages

Using outdated paper logs for recording maintenance data.

Implementing computerised maintenance management systems (CMMS)

Relying solely on the mechanic's memory for service history.

Ignoring diagnostic software and relying on visual inspections only.

Preventive focuses on repairs, while corrective addresses future issues.

Preventive is scheduled maintenance, while corrective is reactionary repairs.

Both involve similar tasks, but corrective maintenance should be priority.

Corrective maintenance is best as preventative maintenance is extra cost.
