PSC Fundamentals
What Is Port State Control?
Port State Control is the inspection of foreign ships in national ports to verify compliance with applicable international maritime regulations.
IMO describes Port State Control as a system through which port States inspect foreign ships visiting their ports to verify that the condition of the ship and its equipment comply with international regulations and that the vessel is properly manned and operated in accordance with those requirements.
The primary responsibility for maintaining a ship to the required standards rests with the flag State. Port State Control acts as an additional safety net by identifying substandard ships that may not be meeting applicable international requirements.
PSC inspections can therefore involve certificates, ship condition, safety equipment, pollution-prevention arrangements, crew certification, manning, working and living conditions, security-related requirements and operational compliance, depending on the applicable instruments and inspection circumstances.
Flag State vs Port State
What Is the Difference Between Flag State Control and Port State Control?
The two functions support maritime compliance from different legal and operational positions.
Flag State
The flag Administration has primary responsibility for ensuring ships entitled to fly its flag comply with applicable international requirements, including survey and certification obligations.
- Primary responsibility for its own fleet
- Ship surveys and statutory certification
- Implementation of applicable conventions
- Authorization and oversight of Recognized Organizations where used
- Enforcement under flag-State jurisdiction
Port State
A port State may inspect foreign ships visiting its ports to verify compliance with applicable international requirements and take appropriate action when deficiencies are found.
- Inspection of foreign ships in port
- Verification of certificates and condition
- Identification of clear grounds
- More detailed inspections when justified
- Deficiency, detention and follow-up procedures
Inspection Process
How Does a Port State Control Inspection Work?
IMO's PSC procedures provide a structured approach for inspection, escalation, deficiency handling and reporting.
1. Ship Selected
A foreign ship is selected for inspection according to the applicable regional or national PSC regime.
2. Initial Inspection
The PSCO begins by examining relevant certificates, documents and the vessel's overall condition.
3. Clear Grounds Considered
If evidence gives reason to believe the ship, equipment or crew may not substantially comply, the inspection can be expanded.
4. More Detailed Inspection
The PSCO examines relevant areas in greater depth according to the deficiencies or concerns identified.
5. Deficiencies Recorded
Any identified deficiencies are documented and assigned appropriate corrective action.
6. Detention Considered
Serious deficiencies may justify detention when the ship is considered unsafe to proceed to sea or presents an unacceptable risk.
7. Rectification
The ship, company, flag State and relevant parties address deficiencies according to the required action.
8. Release & Reporting
Where detention applies, release follows satisfactory rectification or other accepted arrangements, with reporting to relevant authorities.
Clear Grounds
What Are “Clear Grounds” for a More Detailed Inspection?
An initial PSC inspection may be expanded when the PSCO finds evidence suggesting that the ship, equipment or crew may not substantially comply with applicable requirements.
- Missing, invalid or questionable certificates or documents
- Evidence of serious deterioration or poor maintenance
- Indications that essential equipment is not functioning correctly
- Evidence that crew members are unfamiliar with essential procedures
- Operational evidence inconsistent with required standards
- Relevant reports, complaints or information about possible deficiencies
- Previous inspection history or unresolved deficiencies
- Other professional observations that justify closer examination
Inspection Areas
What Can a Port State Control Officer Check?
The exact scope depends on the ship, applicable conventions and inspection findings, but PSC can cover a wide range of statutory and operational areas.
Statutory Certificates
Validity, availability and consistency of certificates and required ship documents.
Hull & Structural Condition
Visible condition and signs that may indicate deterioration affecting safety or compliance.
Machinery & Electrical Systems
Essential machinery, emergency systems and relevant operational readiness.
Fire Safety
Fire detection, firefighting arrangements, escape routes and associated equipment.
Life-Saving Appliances
Lifeboats, liferafts, personal appliances and emergency readiness.
Navigation
Navigation equipment, bridge procedures, charts, publications and operational practice.
Pollution Prevention
MARPOL-related equipment, records, procedures and pollution-prevention controls.
Manning & Certification
Minimum safe manning, STCW certificates and crew competence-related requirements.
Hours of Rest
Records and evidence relating to watchkeeping and applicable work/rest requirements.
ISM Implementation
Evidence that the ship's Safety Management System is effectively implemented onboard.
Security
Applicable SOLAS XI-2 and ISPS-related control and compliance measures.
MLC Conditions
Working and living conditions and related documentation where the Maritime Labour Convention applies.
Deficiencies & Detention
What Is the Difference Between a PSC Deficiency and a Detention?
Not every deficiency results in detention. The seriousness of the deficiency and the risk created by it are central to the action taken.
PSC Deficiency
A deficiency is a condition found during inspection that does not comply with an applicable requirement. The PSCO records the deficiency and specifies the action required, which may range from correction before departure to rectification within another agreed timeframe.
PSC Detention
Detention is a more serious control action used when deficiencies are sufficiently serious that the ship should not proceed to sea until the identified risks are satisfactorily addressed or another permitted arrangement is accepted.
IMO procedures emphasize that all possible efforts should be made to avoid a ship being unduly detained or delayed. Detention decisions should therefore follow the applicable procedures and professional assessment of the deficiencies identified.
Regional Cooperation
What Are the Main Port State Control MoUs?
Regional cooperation helps PSC authorities coordinate inspections, share information and target substandard shipping more effectively.

2025 PSC Procedures
What Changed in the Current IMO Port State Control Procedures?
The latest IMO procedures were adopted in 2025 as resolution A.1206(34), replacing the 2023 edition.
The 2025 update continues IMO's regular two-year revision cycle for global PSC procedures. It updates guidance used by port States when conducting inspections, identifying deficiencies and applying PSC actions.
The update includes revised material in several appendices and new guidance for Port State Control Officers on security aspects. It also updates detainable-deficiency guidance related to areas including ISM implementation, Long-Range Identification and Tracking, certification of seafarers, ship manning and hours of rest.
For training and vessel preparation, the important lesson is that PSC guidance is not static. Course materials, company checklists and pre-arrival preparation should be reviewed against the current IMO procedures and the requirements of the relevant regional PSC regime.
Vessel Readiness
How Should a Ship Prepare for Port State Control?
Strong PSC readiness comes from maintaining statutory and operational standards every day, not from last-minute preparation before arrival.
1. Review Certificates
Confirm statutory and class certificates are valid, available and consistent with vessel particulars.
2. Close Previous Deficiencies
Verify earlier PSC, Flag, class, audit and internal findings have been effectively addressed.
3. Check Safety Equipment
Ensure life-saving, firefighting and emergency equipment is maintained and ready for use.
4. Review Machinery Condition
Address defects, temporary repairs, alarms, emergency systems and maintenance issues.
5. Verify Records
Review logbooks, MARPOL records, rest-hour records, drills and other statutory or operational documentation.
6. Confirm Crew Familiarity
Personnel should understand emergency duties, equipment and procedures relevant to their responsibilities.
7. Walk the Vessel
Use a practical pre-arrival inspection to identify visible safety, housekeeping and maintenance weaknesses.
8. Escalate Real Problems
Report significant issues to shore management early so resources and corrective action can be arranged.
