A pre-vetting audit is the inspection you run on your own ship before an OCIMF-accredited inspector or a charterer's representative walks up the gangway. For the QHSE manager it is the only point in the cycle where findings are still free: a gap found by your own auditor costs a work order, while the same gap found in a published report stays visible for 12 months. Since SIRE 2.0 went live on 2 September 2024, the stakes of that self-check have risen. Each inspection uses a questionnaire compiled by algorithm from the OCIMF Question Library, so the questions cannot be predicted, and every question is assessed across hardware, processes and human factors. This guide gives you the self-check structure across cargo, safety, machinery and documentation, a scorecard to grade readiness, a crew-interview drill and a countdown plan. Start a free trial of Marine Inspection to run the whole self-check on a tablet, offline, with photo evidence attached to every finding.

Why a Pre-Vetting Audit Predicts the Real Inspection
A pre-vetting audit is only useful if it mirrors how the real inspection works. Three features of SIRE 2.0 decide how you should design yours. Book a demo to see how structured self-checks are built around them.
01
No Two Inspections Are Identical
The inspector completes a one-time questionnaire selected by algorithm from the Question Library. You cannot rehearse a fixed list, so your audit must cover every area the library could reach for your ship type.
02
People Are Assessed, Not Just Plant
Inspectors speak to crew and rate what they see against expectations. Knowing why a procedure exists matters as much as having the procedure on file.
03
Core Findings Follow You
Negative observations raised against Core questions are carried forward to the next inspection for the inspector's information. An unfixed gap becomes a repeat question.
One Question, Three Assessments
The reason a weak spot is expensive: the hardware, process and human tools attached to a single question can each produce a negative observation. Your audit should test all three for every system you inspect, never only the equipment.
One Question
e.g. Cargo Tank Inerting
Assessed on three tools
➜
Hardware
Is the system in good condition, tested and recorded?
Processes
Does the written procedure match what the crew actually does?
Human Factors
Can the officer explain the why, not just recite the steps?
Report Lifecycle: The Clocks You Are Working Against
Pre-vetting is a scheduling problem as much as a technical one. Five clocks run at once, and the chart below puts them on one 24-month scale.

Database retention, active period and comment window are OCIMF figures. The 6-month charterer window and 4-6 week lead time are industry practice and vary by charterer.
WHO DECIDES ACCEPTANCE
OCIMF makes the report available for 12 months but does not make vetting decisions. How a report is interpreted, and whether the vessel is acceptable, rests with each report recipient under its own screening criteria. Action for QHSE: ask each regular charterer for its report-age and observation-count policy, and set your audit calendar to the strictest one.
The Four Audit Domains
Divide the self-check into four domains so every officer owns a block and nothing is audited twice. Each domain should be inspected on board with the same discipline as the real thing: open the record, then go and look at the equipment. Build these four domains as digital checklists and assign them to named officers.
Cargo, ballast and inert gas systems operated and recorded as per procedure
Gas detection and oxygen analysers calibrated, with certificates
Pressure/vacuum protection, tank venting and cargo hoses in good order
Mooring equipment inspected, with line and brake records
Manifold, drip trays and spill containment ready for use
Lifesaving and fire-fighting equipment inspected, serviced and logged
Drills conducted to the plan, with lessons recorded and actioned
Enclosed space entry and permit-to-work practised, not just filed
Risk assessments current and known to the people doing the job
PPE issued, fitted and in use on deck
M
Machinery and Engine Room
Emergency generator, steering gear and emergency fire pump tested with records
Oily water separator, monitoring equipment and bilge handling consistent with the Oil Record Book
Planned maintenance up to date, with no overdue critical items
Housekeeping: no oil leaks, clean bilges, clear escape routes
Defects raised, tracked and closed with evidence
D
Documentation and Management
Statutory and class certificates valid, with endorsements in date
Pre-inspection vessel data (HVPQ/PIQ) current and matches the ship
Previous observations closed, each with dated evidence
Safety management system procedures match onboard practice
Shore management self-assessment (TMSA) evidence available
Run the Pre-Vetting Audit From One Tablet
Marine Inspection turns each audit domain into an offline checklist with photo evidence, owner and deadline on every finding, so open items are closed before the inspector arrives.
Pre-Vetting Scorecard: Green, Amber, Red
Grade each area after the self-check. This is a suggested internal scoring model, not an OCIMF grading scheme, but it forces a clear go or no-go before the inspection is requested.
Table 1: Suggested Readiness Scorecard
Human Factors: Audit the Crew, Not Just the Ship
Inspectors observe the people they speak to and rate what they see. Industry guidance describes nine performance influencing factors used to explain why performance fell short, including procedure quality, custom and practice, team dynamics, fatigue and workload, competency and training, and the human-machine interface. Use the four grades below to rate your own crew during mock interviews.
Exceeds Expectations
Capture it as good-practice evidence and share it fleet-wide.
As Expected
Maintain. Repeat the drill next cycle to keep it there.
Largely as Expected
Close the small gaps in coaching before the inspection date.
Not as Expected
Treat as a finding: coach, retrain and record the root cause.
Run the mock interviews as a conversation, not a quiz. Ask the officer to show you, then ask why. Sample prompts to adapt to your fleet:
Master
“Walk me through how you decide to stop cargo operations when conditions change.”
Chief Officer
“Why do we inert cargo tanks, and what do you do when oxygen readings rise?”
Chief Engineer
“Show me how the emergency generator is tested and what you check afterwards.”
Second Officer
“Show me how the passage plan was appraised and the ECDIS safety settings verified.”
Pre-Vetting Countdown
A suggested schedule that works backwards from the inspection. Practitioner guidance puts a full tanker pre-vetting at one to two days onboard, depending on ship size, type and condition. See how Marine Inspection schedules audits and tracks closure against this timeline.
T-6 to 4 wks
Run the independent pre-vetting
Use an auditor from outside the ship's chain of command. Grade every domain on the scorecard.
T-3 wks
Close findings with evidence
Every defect gets an owner, a deadline and a dated photo before it counts as closed.
T-2 wks
Mock interviews
Rate each officer on the four-grade scale and coach anyone below As Expected.
T-1 wk
Data and documents
Refresh vessel data, certificate files and previous-report close-out sheets.
T-72 hrs
Final walk-round
Housekeeping, labelling and spot-checks of the highest-risk systems. Inspections are scheduled at short notice, so stay at this level.

Frequently Asked Questions
What is a pre-vetting audit?
It is an internal inspection run by or for the ship manager to find and fix the same issues an official inspector would raise. It is not a regulatory requirement, but it is the cheapest way to avoid negative observations in a report that charterers will read for the next 12 months.
When should we run it?
Practitioner guidance recommends at least four to six weeks before the current report expires, which leaves time to close findings and re-check them. Many tankers also run one after major crew changes or after a defect that touched a Core system.
Who should carry it out?
Someone outside the ship's own chain of command, such as a fleet superintendent, a QHSE auditor or an external specialist, with the QHSE manager owning the process. A ship auditing itself tends to miss what it has stopped noticing.
Does a good pre-vetting guarantee charterer approval?
No. OCIMF publishes the report, but each recipient applies its own screening criteria and decides acceptability. A clean audit lowers the risk of negative observations but cannot promise approval, which is why you should know each charterer's policy in advance.
How is this different from port state control preparation?
Port state control checks that required procedures and equipment exist and comply with regulations. Vetting goes further by testing whether the crew understands why a procedure exists and whether it works in practice, which is why interviews are central to a pre-vetting audit.
Walk Into Vetting With the Evidence Already Filed
Checklists, photo evidence, corrective actions and audit trails in one system. Marine Inspection keeps every vessel vetting-ready between inspections, not just before them.
