Predictive Maintenance based on IoT Sensors

Predictive and condition-based maintenance are voluntary class- and Company-driven approaches; they replace time-based tasks only within an approved scheme with adequate data and sensors.

Operational Explanation

Predictive and condition-based maintenance are voluntary class- and Company-driven approaches; they replace time-based tasks only within an approved scheme with adequate data and sensors.

Regulatory Reference

Approved PMS/machinery survey arrangement, class notation, maker recommendations, ISM risk assessment and data governance.

Scope of Application

No market forecast or adoption percentage determines maintenance-scheme compliance.

Procedure / How to Complete It

Define failure modes and supported decisions.
Validate sensors, calibration, data quality and baselines.
Integrate alerts into PMS with responsibility and escalation.
Obtain approval before replacing time-based tasks.
Measure performance with documented fleet evidence, not commercial claims.

Practical Example

An anomaly model flags a trend: crew verify sensor and machinery and follow an approved work order; the alert does not automatically cancel PMS.

What Typically Goes Wrong

Citing 70% of new ships, 2024/2034 market values, or presenting predictive maintenance as automatic replacement.

What the PSCO Checks

Evidence of the approved arrangement, procedures, records, competence, defect management and consistency with statutory/class/maker requirements.

Operational Tips

Separate current requirement, class/maker, SMS and voluntary guidance.
Do not improvise tests, thresholds or intervals.
Record deviations and corrective action.

Preparation checklist

Approved scheme
Sensor/data validation
Maker/class alignment
Human review
No unsupported market claims

FAQ

Does predictive maintenance automatically replace PMS?

No. An approved scheme is required.

Are market percentages needed?

No. They were removed as unverifiable and non-operational.
