Overview
This checklist is an IMT practical workflow, not a universal regulatory form. Bunker procedures vary by port, fuel, measurement system and contract, so the surveyor must identify the governing requirements before using any checklist.
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

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.
- Instruction/nomination reviewed.
- Current port procedure identified.
- Opening tank or meter evidence recorded.
- Sampling arrangements recorded where in scope.
- Transfer chronology maintained.
- Closing evidence captured.
- BDN and supporting documents reconciled.
- Any discrepancy/protest documented.
- Final calculations independently checked.
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:
- Using an old checklist without checking the current port standard.
- Leaving document review until after signing.
- Focusing on final quantity while ignoring the evidence trail.

Is this checklist valid in every port?
No. It is a general IMT framework and must be adapted to the port's rules and the agreed delivery method.
Should MFM and tank-gauging checklists be identical?
No. Their measurement evidence and procedural controls differ.
What is the single most important habit?
Create a complete contemporaneous record from before the opening measurement through final document reconciliation.
