Every foreign vessel calling at Piraeus, Thessaloniki, Heraklion, Volos, or any of Greece's major commercial ports risks an unannounced Port State Control inspection that can—within hours—result in a detention costing $40,000–$110,000 per day. Greece operates under the Paris MOU framework, where the 2024 detention rate climbed to 4.03%—the highest in three consecutive years—and fire safety, ISM Code failures, and life-saving appliance deficiencies remain the top causes of vessels being held. Shipowners and operators whose vessels call at Greek ports can start a free trial of Marine Inspection's PSC readiness platform and arrive at every Greek port with documentation verified, deficiencies tracked, and inspection evidence instantly accessible.

What Is Port State Control — And Why Greece Matters
Port State Control is the internationally agreed right of any country to inspect foreign-flagged vessels in its ports to verify compliance with SOLAS, MARPOL, STCW, MLC 2006, and related conventions. It acts as a second line of defence after flag state oversight—and in Greece it is enforced by the Hellenic Coast Guard (HCG) under the authority of the Paris Memorandum of Understanding (Paris MOU), which Greece has been a member of since its founding.
Greece's strategic position makes it unavoidable for vessels trading across the Eastern Mediterranean, Black Sea, and Adriatic routes. Major inspection ports include Piraeus (Europe's largest passenger port), Thessaloniki, Heraklion, Volos, and Patras. See how Marine Inspection prepares vessels for Greek PSC — book a demo.
Greek HCG officers don't inspect randomly. They use the Paris MOU's THETIS targeting system, which calculates each vessel's Ship Risk Profile (SRP) and assigns an inspection priority score. Understanding what drives your risk score is the first step to protecting your vessel.
High Risk Triggers
Previous detentions or deficiencies
Flag state on Paris MOU Grey/Black List
Vessel age over 12 years
Recognized Organization with poor performance
No inspection in last 5–6 months
Low Risk Indicators
Clean inspection record (last 3 visits)
Flag state on Paris MOU White List
Vessel age under 5 years
Reputable Recognized Organization
Inspection window extended to 24–36 months
Key insight: A high-risk vessel may be inspected every 5–6 months in Greek ports; a low-risk vessel's window extends to 24–36 months. Digital deficiency tracking directly improves your SRP over time.
How a PSC Inspection Unfolds in a Greek Port
PSC inspections in Greece follow a structured escalation model. What begins as a routine document check can become a full expanded inspection within minutes if officers find "clear grounds" for concern. Vessels that pass the initial phase with clean documentation almost always avoid the deeper dive—which is why pre-arrival readiness is the single highest-ROI compliance activity a shipowner can invest in.
1
Initial Inspection
⏱ 30–60 min
Officers board and verify statutory certificates (SOLAS, MARPOL, STCW, MLC). Document completeness and validity checked first. If clean — inspection may end here.
✓ Pass = no further inspection required
2
More Detailed Inspection
⏱ 2–4 hours
Triggered by document gaps or "clear grounds." Officers physically inspect safety equipment, fire systems, LSA, machinery spaces, crew quarters, and navigation bridge.
⚠ Deficiencies possible — corrective action required
3
Expanded Inspection
⏱ 4–8 hours
Mandatory for passenger ships, tankers, gas carriers, bulk carriers over 12 years. Covers ISM system effectiveness, emergency drills, crew competency demonstrations, structural condition.
⚠ ISM failures here = near-certain detention
4
Detention / Follow-Up
⏱ Days to weeks
Vessel held in Greek port until detainable deficiencies are rectified and re-inspected. Costs accumulate daily. Result recorded in THETIS — impacts future risk score globally.
$40K–$110K/day + global reputation damage

Never Arrive at a Greek Port Unprepared Again
Marine Inspection's PSC readiness module automates pre-arrival checklists, certificate monitoring, deficiency tracking, and THETIS risk score management — purpose-built for vessels calling at Paris MOU ports including Greece.
When Deficiencies Are Found: The Aftermath You Need to Understand
Not every deficiency means detention — but every deficiency goes on record. Understanding the difference between actionable and detainable deficiencies, and how both affect your future inspection frequency in Greek and other Paris MOU ports, is critical for long-term compliance strategy.
Clean Report
No deficiencies found. Report recorded in THETIS. Ship Risk Profile improves. Inspection window extended — lower chance of being targeted at next port.
Action: Maintain standards. Document clean result for charterers.
Deficiencies — Rectify at Next Port
Minor issues flagged. Vessel may sail but must correct deficiencies and demonstrate compliance at next port of call. Recorded in THETIS — raises risk score.
Action: Track deficiencies digitally. Confirm correction before next PSC port.
Deficiencies — Rectify Before Departure
More serious issues. Vessel grounded until specific deficiencies corrected and re-verified by PSC officer in Greek port. Port costs accumulate. Timetable disrupted.
Action: Immediate repair. Request re-inspection when ready. Costs begin immediately.
Detention
Vessel cannot leave Greek port. Detainable deficiencies pose safety risk. $40K–$110K/day in costs. THETIS record follows vessel globally. Risk score spikes — more frequent future inspections.
Action: Notify flag state, class society. Rectify, request HCG re-inspection. Consider PR impact.
"We had two detentions in Piraeus in eighteen months — both for the same category: certificate discrepancies our shore team had missed. The financial damage was significant, but worse was the THETIS hit. Suddenly our vessels were being inspected at almost every port call across Europe. Since deploying digital deficiency and certificate management, we have had zero detentions across 14 port calls in Greek waters. Our pre-arrival preparation has gone from two days of document hunting to a 45-minute automated checklist review. The platform paid for itself in the first clean inspection."
2025–2026 Paris MOU Concentrated Inspection Campaigns (CICs): What's in Focus Now
Beyond routine inspections, the Paris MOU coordinates annual Concentrated Inspection Campaigns where all member states — including Greece — apply heightened scrutiny to one specific topic for three months. The Paris MOU and Tokyo MOU are running a joint CIC on Ballast Water Management from September 1 to November 30, 2025. Vessels calling at Greek ports during this window face targeted questioning on ballast water treatment systems, record books, and certificates. Operators can book a demo to see how Marine Inspection tracks CIC requirements.

Operators ready to implement a PSC readiness platform — book a demo can put Marine Inspection's purpose-built system to work across their entire fleet operating in Greek and European waters.
Frequently Asked Questions
How does the Paris MOU THETIS system decide which vessels get inspected in Greek ports?
THETIS assigns each vessel a Ship Risk Profile (SRP) based on vessel age, flag state performance (White/Grey/Black List), recognized organization performance, inspection history, and previous deficiencies or detentions. High-risk vessels can be inspected every 5–6 months; low-risk vessels every 24–36 months. Greek HCG officers use THETIS to prioritize which vessels receive mandatory, priority, or standard inspections. Maintaining clean inspection records over time directly improves your SRP and reduces inspection frequency.
What are the most common reasons vessels are detained in Greek and European ports in 2024–2025?
According to the Paris MOU 2024 Annual Report, fire safety (17.2% of deficiencies), structural and electrical equipment (11.3%), and MLC crew welfare (10.4%) are the top three deficiency categories. ClassNK's 2024 PSC report confirms fire safety, life-saving appliances, and ISM Code violations as the leading causes of vessel detention. At a granular level, fire door failures, expired pyrotechnics, oil record book discrepancies, and ECDIS configuration errors are among the most common individual findings.
What is a Concentrated Inspection Campaign (CIC) and how does it affect vessels in Greece?
CICs are annual campaigns where Paris MOU member states, including Greece, focus on one specific topic during a three-month inspection period. All vessels inspected during a CIC receive additional scrutiny on the campaign topic, regardless of their normal risk profile. The Paris MOU and Tokyo MOU are running a joint CIC on Ballast Water Management from September 1 to November 30, 2025. Vessels calling at Greek ports during this window should ensure their BWMS certificate, Ballast Water Management Plan, and Record Book are current and crew can demonstrate system operation.
How can digital deficiency tracking software reduce PSC detention risk in Greek ports?
Digital platforms reduce detention risk in three ways: (1) Preventing certificate gaps — automated 90-day warnings eliminate the 8–12% annual certificate expiration rate that triggers immediate deficiency notices; (2) Systematic pre-arrival preparation — automated checklists covering fire safety, LSA, MARPOL, crew certs, and ISM documentation ensure nothing is missed before HCG officers board; (3) Deficiency management — tracking corrective actions from previous inspections and confirming completion prevents repeat deficiencies that raise THETIS risk scores. Operators using Marine Inspection report 65% fewer deficiency notices and zero detentions over 18-month periods.
What happens if my vessel is detained in Piraeus or another Greek port?
A detained vessel cannot leave the Greek port until all detainable deficiencies are corrected and re-verified by an HCG Port State Control officer. Costs include port fees, crew overtime, charter penalties, and lost revenue typically totalling $40,000–$110,000 per day. The detention is recorded in THETIS and affects the vessel's global Ship Risk Profile — increasing inspection frequency at every subsequent Paris MOU and Tokyo MOU port for the following 3-year rolling period. Flag state and class society must also be notified. A classification surveyor can assist with faster deficiency rectification to minimize detention duration.
