A Well-Maintained Vessel Is More Than a Well-Organized File
When preparing for vessel inspections, I initially assumed that reviewing a Planned Maintenance System (PMS) was largely a documentation exercise.
Check maintenance records.
Verify completion dates.
Review overdue jobs.
Move on.
The more vessels I studied, however, the more I realized that maintenance management cannot be evaluated through paperwork alone.
A perfectly completed PMS does not necessarily mean the vessel is well maintained.
Likewise, a vessel with limited digital records is not automatically poorly managed.
The challenge for surveyors is determining whether maintenance activities actually reflect the condition of the ship.
That is where professional judgement becomes important.
PMS, CMS and Different Approaches to Maintenance
Most modern vessels operate under a computerized Planned Maintenance System (PMS).
The concept is straightforward.
Maintenance tasks are scheduled based on:
- Running hours
- Calendar intervals
- Manufacturer recommendations
- Company requirements
The system records completion history and provides traceability.
However, not every vessel operates under a fully approved PMS scheme.
Particularly on older vessels, surveyors may still encounter Continuous Machinery Survey (CMS) arrangements.
In these cases, the classification society monitors machinery through a structured survey cycle rather than relying entirely on an approved PMS framework.
From an inspection perspective, the question remains the same:
Is the machinery actually being maintained?
Looking Beyond Maintenance Checkmarks
One lesson I learned early is that maintenance records should never be viewed in isolation.
An experienced surveyor rarely accepts a maintenance record at face value.
Instead, multiple sources of information are compared.
For example:
Main Engine Running Hours
Generator Running Hours
Maintenance History
Performance Records
Alarm History
Spare Parts Consumption
Chief Engineer’s Explanation
When these records tell a consistent story, confidence increases.
When inconsistencies appear, additional questions naturally follow.
A Timeline Often Reveals More Than a Single Record
One technique frequently used by experienced inspectors is timeline verification.
Instead of reviewing a single maintenance entry, the surveyor follows the machinery history over time.
For example:
A purifier overhaul may be recorded in the PMS.
The surveyor may then compare:
- Running hours before overhaul
- Spare parts usage
- Maintenance log entries
- Performance trends after overhaul
The objective is not to catch mistakes.
The objective is to determine whether the records reflect actual maintenance activity.
Sometimes the timeline makes perfect sense.
Sometimes it does not.
This is where professional discretion becomes valuable.
The Importance of Surveyor Judgement
Modern inspection programs increasingly emphasize evidence-based verification.
However, inspection still requires human judgement.
In my opinion, one of the most important skills a surveyor can develop is the ability to identify inconsistencies across multiple information sources.
A surveyor should be capable of discerning operational reality through documents such as:
- PMS Records
- CMS Survey History
- Running Hour Logs
- Alarm Histories
- Performance Records
- Oil Analysis Reports
- Defect Reports
- Spare Parts Records
- Engine Logbooks
Individually, each document provides only part of the picture.
Together, they reveal the overall maintenance culture onboard.
SMS Is More Than a Manual
The same principle applies to the Safety Management System (SMS).
Many junior officers view the SMS as a collection of procedures.
In reality, inspectors are interested in something much broader.
The question is not:
Does the vessel have an SMS?
The question is:
Is the SMS actually being used?
Most shipping companies have similar SMS structures because they are ultimately based on ISM Code requirements.
However, implementation quality varies significantly between companies.
Some companies treat SMS as a compliance document.
Others use it as an active management tool.
The difference becomes obvious during inspections.
Risk Assessments and Permit to Work Systems
One area receiving increasing attention is the quality of Risk Assessments (RA) and Permit to Work (PTW) systems.
Modern inspections rarely focus only on whether a permit exists.
Inspectors often evaluate:
- Is the RA specific to the task?
- Do crew members understand the hazards?
- Is the PTW completed correctly?
- Are control measures realistic?
- Was toolbox talk conducted?
A perfectly completed permit means little if the crew cannot explain the associated risks.
Human Factors Are Becoming More Important
One trend I continue to observe is the growing emphasis on crew familiarity and system understanding.
This is particularly visible in modern inspection programs such as RightShip RISQ and SIRE 2.0.
Advanced vessels now operate increasingly complex systems:
- Ballast Water Treatment Systems
- Scrubbers
- Reliquefaction Plants
- Energy Efficiency Systems
- Integrated Automation Systems
The equipment itself is often highly reliable.
The larger risk is frequently the operator.
Inspectors are therefore paying closer attention to:
- Operational knowledge
- Alarm interpretation
- System understanding
- Decision making
rather than focusing solely on equipment condition.
Internal Audits Often Reveal Company Culture
Another useful indicator is the quality of internal audits and superintendent inspections.
Well-managed companies typically demonstrate:
- Detailed audit findings
- Meaningful corrective actions
- Follow-up verification
- Continuous improvement
Poorly managed systems often generate repetitive observations with limited evidence of improvement.
For surveyors, these records provide valuable insight into the company’s overall management philosophy.
What Surveyors Are Really Trying to Verify
Ultimately, surveyors are not simply checking whether maintenance tasks have been completed.
They are trying to determine whether the vessel is being managed in a controlled and professional manner.
The best vessels usually demonstrate consistency between:
- PMS Records
- Machinery Condition
- Crew Knowledge
- SMS Implementation
- Operational Performance
When these elements align, confidence naturally increases.
Final Thoughts
In my experience, successful inspections rarely depend on a single document or a single piece of equipment.
The real challenge is connecting information from multiple sources and understanding the story they collectively tell.
A maintenance record may indicate that a task was completed.
A performance trend may indicate whether it was effective.
A discussion with the Chief Engineer may reveal whether the crew truly understands the system.
Modern inspections increasingly focus on these connections.
Because ultimately, good ship management is not demonstrated by paperwork alone.
It is demonstrated by consistency between documentation, equipment condition, and human performance.
