What professionals need to understand
An onboard complaint procedure should give seafarers a practical route to raise concerns while protecting their rights under the applicable MLC implementation.
The strongest approach is to connect the written requirement or procedure to what can actually be observed, demonstrated and recorded. A certificate or completed form is useful evidence, but it does not replace verification of the underlying condition or activity. Scope also matters: vessel type, flag, trade, cargo, equipment and local requirements can change what is applicable.
This guide is designed as a practical learning resource. It deliberately separates general professional practice from official requirements, and it should be used alongside current primary sources and the ship or company’s approved procedures.
Key checks and evidence points
Make the procedure accessible.
Explain escalation routes.
Protect against victimization.
Keep appropriate records.
Respect confidentiality where required.
Ensure shore contacts are current.
These points are not intended to be a universal statutory checklist. They are prompts for a structured review. Where a requirement is not applicable, record the basis rather than forcing the item into the scope.
A disciplined working method
- Define scope. Confirm the vessel, operation, assignment, applicable procedure and objective before collecting evidence.
- Review documents. Identify the certificates, records, plans, logs or instructions relevant to the scope.
- Verify condition and practice. Compare documents with what is physically present and what personnel can demonstrate.
- Record objective evidence. Note facts, dates, identifiers, measurements or observations clearly enough for another competent reader to follow.
- Manage exceptions. Escalate safety-critical issues and distinguish defects, observations and limitations according to the applicable system.
- Close the loop. Track corrective action, supporting evidence and verification where follow-up is required.
Practical review checklist
- Make the procedure accessible.
- Explain escalation routes.
- Protect against victimization.
- Keep appropriate records.
- Respect confidentiality where required.
- Ensure shore contacts are current.
Quality-control questions
- Does the record match the actual condition or operation?
- Is the source current and applicable to this vessel and scope?
- Can another competent person reproduce or understand the conclusion?
- Are limitations, exceptions and unresolved items stated clearly?
- Is corrective action supported by objective evidence rather than a completion tick alone?
