Overview

This IMT checklist is designed for audit preparation and internal review. It does not replace the instruments themselves. Its main purpose is to stop a combined audit from becoming one blended checklist where nobody can see which requirement a piece of evidence supports.

For maritime professionals, the useful question is not only “what does the term mean?” but “what evidence would show that the work was performed properly?” This guide therefore focuses on the practical link between the governing framework, onboard or cargo-side activity, and the records a competent professional would expect to see.

Key Points to Understand

01ISM evidence should show an operating safety-management system.
02ISPS evidence should show assessment-based security controls and implementation.
03MLC evidence should show compliance with seafarer working and living standards under the amended Convention.
04Cross-cutting topics such as training, records and corrective action can be coordinated without losing the source criterion.

Practical Process

The exact method must always be adapted to the vessel, cargo, company procedures, local rules and the scope of the assignment. A disciplined sequence helps keep evidence complete and prevents the work from drifting away from its objective.

  1. Map each checklist line to ISM, ISPS or MLC criteria.
  2. Review documents before interviews.
  3. Sample implementation onboard and ashore.
  4. Record objective evidence and gaps.
  5. Classify findings against the correct criterion.
  6. Agree corrective-action ownership and follow-up.
Evidence principle: write down what was actually checked, how it was checked, and any limitation that could affect the conclusion. A clear limitation is stronger than an unsupported assumption.

Common Mistakes

Most weak inspections, surveys and audits do not fail because the professional forgot a complicated formula. They fail because scope, evidence or follow-up became unclear. Watch especially for:

  • One combined finding that mixes three unrelated requirements.
  • Repeating the same evidence without checking whether it actually satisfies each framework.
  • Closing findings on document revision alone when implementation is still weak.

Practical Checklist

This is an IMT working checklist, not a substitute for the applicable convention, code, flag requirement, port rule, company procedure or contractual instruction.

  • ISM policy/risk/SMS
  • ISM reporting/audit
  • ISPS assessment/plan
  • ISPS access/drills
  • MLC employment/work-rest
  • MLC accommodation/welfare
  • Findings/corrective action

Frequently Asked Questions

Is this an official IMO or ILO checklist?

No. It is an IMT practical preparation tool. The governing criteria remain the applicable IMO and ILO instruments.

Can evidence be shared across frameworks?

Yes, where genuinely relevant, but the audit trail should still show which criterion the evidence supports.

What is the biggest risk in a combined audit?

Losing criterion clarity and producing broad findings that are difficult to correct or verify.
