ISM Deficiencies During Port State Control

What professionals need to understand

PSC findings can expose weaknesses in how a Safety Management System is implemented rather than merely how it is written. Repeated technical defects, weak corrective action or poor familiarization can indicate a broader management-system problem.

The strongest approach is to connect the written requirement or procedure to what can actually be observed, demonstrated and recorded. A certificate or completed form is useful evidence, but it does not replace verification of the underlying condition or activity. Scope also matters: vessel type, flag, trade, cargo, equipment and local requirements can change what is applicable.

This guide is designed as a practical learning resource. It deliberately separates general professional practice from official requirements, and it should be used alongside current primary sources and the ship or company’s approved procedures.

Key checks and evidence points

These points are not intended to be a universal statutory checklist. They are prompts for a structured review. Where a requirement is not applicable, record the basis rather than forcing the item into the scope.

A disciplined working method

1. Define scope. Confirm the vessel, operation, assignment, applicable procedure and objective before collecting evidence.
2. Review documents. Identify the certificates, records, plans, logs or instructions relevant to the scope.
3. Verify condition and practice. Compare documents with what is physically present and what personnel can demonstrate.
4. Record objective evidence. Note facts, dates, identifiers, measurements or observations clearly enough for another competent reader to follow.
5. Manage exceptions. Escalate safety-critical issues and distinguish defects, observations and limitations according to the applicable system.
6. Close the loop. Track corrective action, supporting evidence and verification where follow-up is required.

Practical review checklist

• Compare written procedures with actual practice.
• Review recurring defects for systemic causes.
• Check corrective and preventive action quality.
• Confirm reporting lines and DPA escalation are understood.
• Review internal audit follow-up.
• Verify familiarization and training records against demonstrated competence.

Quality-control questions

• Does the record match the actual condition or operation?
• Is the source current and applicable to this vessel and scope?
• Can another competent person reproduce or understand the conclusion?
• Are limitations, exceptions and unresolved items stated clearly?
• Is corrective action supported by objective evidence rather than a completion tick alone?
