Port State Control Inspections: How to Prepare Your Yacht

A Port State Control inspection can happen at any port, at any time, with little or no advance notice. For superyacht operators who have spent months focused on interior refit, guest itineraries, and charter schedules, the knock on the hull from a PSCO can be an unwelcome surprise. The reality is that PSC inspections are increasing for large yachts, and the consequences of a poor result range from delays and deficiency reports to outright detention.

I have been through dozens of PSC inspections, both as the Chief Engineer being questioned and as the person preparing the vessel beforehand. The difference between a smooth inspection and a painful one almost always comes down to preparation. This guide covers what PSCOs look for, how the targeting system works, and exactly how to get your yacht ready.

Who Needs This?

PSC inspections can target any foreign-flagged vessel in port. If any of the following apply to you, this guide is essential reading:

• Any yacht of 500 GT and above on international voyages is subject to PSC inspection
• Yachts operating under the ISM Code will have their SMS examined
• Yachts in Paris MOU or Tokyo MOU member states (which covers most of Europe, Asia-Pacific, and beyond)
• Yachts with previous deficiencies or detentions face a higher probability of re-inspection
• Charter yachts visiting multiple jurisdictions encounter different PSC regimes frequently
• New-build yachts on maiden voyages are sometimes targeted for initial verification

What Is Port State Control?

Port State Control is the inspection regime that allows a coastal state to verify that foreign-flagged vessels in its ports comply with international conventions. The legal basis comes from several IMO instruments, most notably SOLAS Chapter I, Regulation 19 and MARPOL Article 5(2).

PSC operates through regional agreements known as Memoranda of Understanding (MOUs). The two most relevant for superyachts are the Paris MOU (covering Europe and the North Atlantic) and the Tokyo MOU (covering Asia-Pacific).

How Targeting Works

PSC inspections are not random. Both the Paris MOU and Tokyo MOU use a ship risk profile system to prioritise which vessels to inspect.

The Paris MOU New Inspection Regime (NIR), in effect since 1 January 2011, calculates a Ship Risk Profile (SRP) based on:

Vessels are classified as Low Risk Ship (LRS), Standard Risk Ship (SRS), or High Risk Ship (HRS). The inspection window varies accordingly: LRS may go 24-36 months between mandatory inspections, while HRS vessels face inspection within 5-6 months.

What PSCOs Check

A PSC inspection typically begins as an initial inspection and may escalate to an expanded (more detailed) inspection if the PSCO finds clear grounds. Understanding the difference is important.

Initial Inspection

The initial inspection covers verification of certificates, documents, and the general condition of the vessel. The PSCO will typically:

1. Check statutory certificates (Safety Equipment Certificate, Safety Radio Certificate, Safety Construction Certificate, IOPP Certificate, ISSC, DOC/SMC, etc.)
2. Review the ISM Code compliance (Safety Management Certificate, Document of Compliance, evidence of internal audits, Master’s reviews)
3. Examine MARPOL documentation (Oil Record Book, Garbage Record Book, SOPEP, bunker delivery notes)
4. Verify crew certificates (STCW certificates, endorsements, medical certificates, Safe Manning Document)
5. Conduct a general walkthrough of the vessel to assess overall condition

Expanded Inspection

If the PSCO identifies “clear grounds” for a more detailed inspection, the scope expands significantly. Clear grounds include:

• Missing or expired certificates
• Evidence that crew cannot perform essential duties
• Oil Record Book irregularities
• Vessel or equipment in poor condition
• Previous detention history

During an expanded inspection, the PSCO may:

• Test safety equipment (launch a lifeboat davit, test fire pumps, activate emergency lighting)
• Interview crew members on their duties and emergency procedures
• Examine the SMS in detail (procedures, drills records, maintenance records, non-conformity reports)
• Check structural and mechanical condition (hull, machinery, electrical systems)
• Verify ISPS Code compliance (security plan, security drills, access control)

Most Common Deficiencies on Yachts

Based on published Paris MOU and Tokyo MOU data and our team’s experience, these are the deficiency categories that appear most frequently on superyachts:

Certificate and Documentation Issues

• Expired or missing statutory certificates
• Safety Manning Document not reflecting actual crew complement
• STCW certificates without valid flag state endorsements
• Oil Record Book entries incomplete or unsigned
• SOPEP not approved or contact details outdated

ISM Code Deficiencies

• Internal audits not conducted within 12-month intervals
• Master’s review not documented annually
• Non-conformities raised but corrective actions not closed out
• Drills not conducted at required intervals (abandonment drill monthly, fire drill monthly under SOLAS III/19.3)
• Crew unable to describe their emergency duties when interviewed

Safety Equipment

• Liferaft hydrostatic releases expired or incorrectly fitted
• Fire extinguishers overdue for inspection or service
• EPIRB or SART batteries expired
• Emergency lighting not functioning
• Pilot ladder not compliant with SOLAS V/23

MARPOL Compliance

• Oily water separator not operational or no evidence of testing
• Garbage management plan missing or not followed
• Sewage treatment plant not functioning correctly
• International Air Pollution Prevention (IAPP) Certificate issues on larger yachts

• Oil Record Book Part I current, entries complete and signed
• SOPEP onboard, approved, and contact details verified
• Garbage Record Book current with entries for last two years
• Garbage Management Plan posted and current
• Bunker Delivery Notes for last three years available
• Fuel oil samples sealed and labelled correctly

How to Handle the Inspection

When the PSCO arrives, how you manage the process matters. A cooperative, organised approach sets the right tone.

1. Designate a point of contact. Typically the Master or Chief Officer meets the PSCO, with the Chief Engineer available for machinery and MARPOL matters.

2. Have certificates organised and accessible. A certificate folder in bridge order, with an index, saves time and demonstrates organisation.

3. Be honest. If something is deficient, say so. Attempting to conceal a deficiency is far worse than disclosing it. PSCOs are experienced professionals and they will find it.

4. Take notes. Record everything the PSCO examines, comments on, or questions. This is invaluable for addressing findings and preparing for future inspections.

5. Do not argue. If you disagree with a finding, note it respectfully and raise it through formal channels (your flag state or classification society) after the inspection.

6. Provide a comfortable workspace. Offer the PSCO a table, power for their laptop, and refreshments. Professional courtesy goes a long way.

Detention: What It Means and How to Avoid It

Detention means the vessel is not permitted to sail until the deficiency is rectified to the PSCO’s satisfaction. A detention is recorded in the MOU database and affects your Ship Risk Profile for three years.

Grounds for detention include any deficiency that renders the vessel unseaworthy or presents an unreasonable threat to the marine environment. In practice, this means expired critical certificates, non-functioning safety equipment, or evidence of falsified records.

The most effective way to avoid detention is simple: maintain your vessel to standard, keep your documentation current, and conduct regular self-inspections using the same criteria a PSCO would apply. Our SMS Essentials Package includes pre-inspection checklists aligned with Paris MOU inspection procedures and all the core MARPOL and ISM documentation templates you need to maintain continuous compliance.

Frequently Asked Questions

Can I refuse a PSC inspection?

Technically, a Master can refuse to allow a PSCO onboard. In practice, this is almost never advisable. Refusal is itself grounds for detention under most MOU procedures, and the vessel will be treated as having the worst possible risk profile. The only legitimate reason to delay an inspection is if the vessel is engaged in an emergency operation. Cooperate fully and professionally.

How long does a typical PSC inspection take?

An initial inspection usually takes two to four hours. An expanded inspection can take a full day or more, depending on the scope and the deficiencies identified. The best way to keep the duration short is to have everything organised and accessible from the start. Delays in locating documents or certificates extend the inspection and increase scrutiny.

What happens after a deficiency is recorded?

For non-detainable deficiencies, the PSCO will issue a deadline for rectification, typically 14 days. The deficiency is recorded in the MOU database and your flag state is notified. You must rectify the issue and provide evidence to either the issuing authority or the PSC authority at the next port. Failure to rectify within the deadline can escalate the deficiency and affect future inspections.
