Overview
Port State Control is the inspection of foreign ships in national ports to verify compliance with applicable international requirements for the ship, equipment, manning and operation. IMO describes PSC as a second line of defence against substandard shipping.
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 the ship's statutory certification and records.
- Review recent deficiencies and corrective-action evidence.
- Check safety, pollution-prevention and operational readiness onboard.
- Ensure crew can demonstrate required procedures and equipment use.
- Respond professionally to inspector requests and record deficiencies accurately.
- Close deficiencies with evidence and follow the applicable reporting process.
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:
- Treating PSC as a paperwork inspection only.
- Hiding known defects instead of managing and reporting them appropriately.
- Using outdated PSC procedure references.
