Port State Control Inspection — Complete Seafarer Guide 2026

Port State Control (PSC) is the system by which port countries inspect foreign ships to verify they comply with international maritime conventions. Every ship, every port, potentially every visit. Understanding PSC is essential for every officer — and for every cadet who wants to understand why ships have so much paperwork.

What Is Port State Control?

When your ship enters a port, the port country has the right to inspect it. This right is established by international conventions (SOLAS, MARPOL, MLC 2006, STCW). The inspecting officer is typically a government maritime official.

Why it exists: Flag states (where ships are registered) don’t always enforce international standards. PSC catches ships that are substandard — unseaworthy, undermanned, equipment defective, crew untrained or uncertified.

The Three Major PSC Regimes

India is part of the Indian Ocean MOU. Ships are inspected in Indian ports by MMD (Mercantile Marine Department) surveyors acting as PSC inspectors.

The Tokyo MOU and USCG are the most stringent and feared by shipping companies.

What PSC Inspectors Check

Initial Inspection (Every Ship)

• All statutory certificates valid (SOLAS, MARPOL, Load Line, Safety Management)
• Ship’s log and voyage records
• Crew list and certificates (every officer’s STCW CoC verified)
• Working hours and rest records (MLC compliance)
• Drug and alcohol policy

Expanded Inspection (Triggered by Risk Factors)

If the initial check finds problems, or if the ship has a high-risk profile (previous deficiencies, first call, overdue survey), the inspector expands:

Structural and Safety:

• Lifeboats: launching test, fall wire condition, hydrostatic releases
• Fire detection and suppression systems
• GMDSS equipment — tested operationally
• Watertight integrity — hatches, doors, closing devices

MARPOL Compliance:

• Oil Record Book — checked against engine log
• Garbage Record Book
• Sewage treatment system or holding tank
• SOPEP (Shipboard Oil Pollution Emergency Plan) onboard

MLC 2006 — Seafarer Welfare:

• Crew accommodation spaces — size, ventilation, sanitation
• Crew food and catering
• Wages — are seafarers being paid? Employment agreements onboard?
• Medical supplies and sick bay
• Complaint procedure posted

ISPS (Security):

• Ship Security Plan accessible
• Security officer designated
• Access control records

Common Deficiencies Found in PSC

Based on published Tokyo MOU and Paris MOU annual reports, the most common deficiencies:

1. Fire safety — fire detection, firefighting equipment maintenance failures
2. Life saving appliances — lifeboat equipment, immersion suits, EPIRBs
3. Working hours — rest hours records falsified or genuinely violated
4. MARPOL — Oil Record Book — incorrect entries, missing signatures
5. Certificates — officer certificates expired or not properly endorsed
6. ISM Code — safety management system not functioning

Detention — When It Happens

If deficiencies are serious enough to threaten safety or the environment, the inspector issues a detention. The ship cannot leave port until deficiencies are rectified.

Automatic detention triggers:

• Any officer on watch without a valid CoC
• EPIRB not operational or expired
• Fire detection system inoperable
• Safety certificates expired
• Evidence of deliberate MARPOL violations

Cost of detention:

• Port dues continue during detention (€5,000–20,000/day in European ports)
• Crew overtime
• Cargo claim from charterers for delay
• Company reputation damaged (published online in PSC databases)
• Repeat offenders get “concentrated inspection” on future visits

Your Role During a PSC Inspection

If you’re the OOW when the inspector arrives:

• Greet professionally, check inspector’s ID
• Notify the Master immediately
• Do not offer information beyond what is asked — answer questions directly and accurately
• If you don’t know something, say “I’ll get the Master/Chief Engineer”
• Never argue with an inspector about a deficiency — note it and let the company handle dispute

If you’re a cadet:

• Don’t speak unless addressed
• If asked about rest hours, answer honestly — false rest records are a criminal matter

Critical: Never falsify rest records because management pressures you. You are the one who signed the record. You are the one who can face criminal charges.

The PSC Black List / White List

Each MOU maintains a performance list of flag states:

• White list: Good compliance — low deficiency rate
• Grey list: Moderate — increased scrutiny
• Black list: Poor compliance — ships face automatic expanded inspection

India is typically on the white or grey list. Flags like Panama, Liberia, Marshall Islands vary by year. Check the latest published Tokyo MOU annual report for current rankings.

Individual ships also have a targeting score — based on previous deficiencies, ship age, flag performance. High-scoring ships get inspected more frequently.
