An ISM audit is not decided on the day of the visit but in the six months before it. The annual internal audit required by the Code exists precisely for that: to find your non-conformities before the administration or the classification society does. The checklist below follows the points auditors raise in practice, in the order they raise them.
1. Safety management system documentation
Is the SMS manual current in the version actually distributed on board? Do the procedures describe what the crew does, or what it should do according to an organisation that has since changed? Is the designated person ashore identified, known to the crew and reachable?
The most frequent gap fits in one sentence: procedures written for the previous audit and never revised after a reorganisation. For the framework, our article on the ISM Code applied on board covers the obligations element by element.
2. Maintenance, the most closely examined element
Element 10 of the Code requires a maintenance system for the ship and its equipment. In practice the auditor will ask for four things: the maintenance plan, the records of work carried out with their dates and signatories, the particular treatment given to critical equipment, and the consistency between observed failures and the corrective actions taken.
A complete and searchable maintenance history answers all four in minutes. A paper binder rarely does, and never in front of the auditor.
3. Certificates and due dates
Ship and crew: statutory certificates, surveys, STCW licences, medical fitness. The auditor checks two things, that nothing has expired and that an alerting mechanism makes this repeatable. A registry with alerts at 90, 60 and 30 days allows you to answer in minutes with the evidence to hand.
4. Logs and records
Bridge log, engine room log, drill registers, non-conformity reports. The auditor's request is always the same: show me. How quickly the ship retrieves a specific record says more about the reality of the system than the content of the manual.
5. Non-conformities and the improvement loop
A company declaring no non-conformity at all worries an auditor more than it reassures. The Code expects a complete loop: detection, root cause analysis, corrective action, verification of effectiveness. Prepare two or three cases documented end to end. They are the best evidence that the system is alive, and they fill part of the interview usefully.
6. Inspection readiness, handled in parallel
Deficiencies raised during a Port State Control inspection feed the ISM audit directly, and the reverse is equally true. Preparing both from the same records avoids doing the work twice.
Turning preparation into routine
Audit preparation stops being a sprint the day records are created as work happens: the job logged on board when it is done, the certificate tracked automatically, the non-conformity recorded as soon as it is raised. That is what a CMMS in daily use produces, and where our complete maritime CMMS guide begins. To see it applied to your fleet, ask for a demonstration.
