Overview
Flag States are responsible for implementing and enforcing applicable international requirements on ships entitled to fly their flag. Flag inspection and statutory oversight therefore sit at the first line of regulatory implementation, with PSC acting as a complementary port-State control layer.
For maritime professionals, the useful question is not only “what does the term mean?” but “what evidence would show that the work was performed properly?” This guide therefore focuses on the practical link between the governing framework, onboard or cargo-side activity, and the records a competent professional would expect to see.
Key Points to Understand

Practical Process
The exact method must always be adapted to the vessel, cargo, company procedures, local rules and the scope of the assignment. A disciplined sequence helps keep evidence complete and prevents the work from drifting away from its objective.
- Confirm flag-specific instructions and inspection scope.
- Review statutory certificates and recognised-organisation status.
- Check open conditions, exemptions, memoranda and outstanding survey items.
- Inspect critical equipment and records.
- Verify company/ship reporting of defects and corrective actions.
- Prepare responsible officers to demonstrate systems and records.
Common Mistakes
Most weak inspections, surveys and audits do not fail because the professional forgot a complicated formula. They fail because scope, evidence or follow-up became unclear. Watch especially for:
- Assuming class attendance replaces all flag responsibilities.
- Using generic checklists without flag-specific instructions.
- Failing to escalate statutory defects.
Practical Checklist
This is an IMT working checklist, not a substitute for the applicable convention, code, flag requirement, port rule, company procedure or contractual instruction.
- Flag instructions
- Certificates
- Class/statutory status
- Open items
- Equipment
- ISM
- Defect reporting
- Corrective action

What is the difference between flag State and port State control?
Flag States oversee ships flying their flag; port States inspect foreign ships visiting their ports as an additional control.
Can a recognised organisation conduct statutory surveys?
Flag administrations may authorise recognised organisations for specific statutory functions, while the flag State retains its responsibilities under the applicable framework.
Why review open survey items before inspection?
They are part of the ship's compliance status and may require planned action, conditions or reporting.
