Bunker Delivery Note and Fuel Sample Retention Audit

It covers the records and physical evidence tied to bunker fuel deliveries: the bunker delivery note, the representative fuel sample, and the storage conditions for both. The template is built to verify completeness, retention period, labeling, accessibility, and sign-off. It also gives you a place to document deficiencies and corrective actions when a record or sample is missing or not traceable.

A shipboard compliance lead, marine superintendent, terminal operations manager, or designated records custodian can run it, depending on where the audit is performed. The key is that the person understands the fuel chain of custody and can access the retained documents and samples. If the audit is used during an internal compliance review, a trained inspector or auditor should verify the evidence rather than relying on verbal confirmation.

Use it whenever you want to verify ongoing MARPOL Annex VI record retention, such as during scheduled internal audits, port-state readiness checks, or after a fuel delivery program change. Many organizations run it on a periodic cadence and also after any issue with a missing BDN, damaged sample, or record retrieval delay. The template works well as a recurring checklist because it tracks both current deliveries and older retained records.

The template is aligned to MARPOL Annex VI expectations for bunker delivery notes and representative fuel oil samples. It helps confirm that delivery records are retained for the required period and that samples are kept for the required duration or until substantially consumed, whichever is longer. It is also useful as supporting evidence in broader marine compliance programs and audit trails.

Common issues include missing supplier or vessel details on the bunker delivery note, unsigned or incomplete delivery records, and samples that are not clearly labeled to match the delivery. Auditors also find retention gaps, such as records that cannot be produced quickly or samples stored in unsecured or wet areas. Another frequent problem is keeping a sample, but not being able to link it to a specific delivery.

Yes. The structure already supports vessel, terminal, and fuel storage location audits, so you can tailor the identification fields and evidence prompts to your operation. You can also add local document control steps, internal file locations, or custody handoff fields without changing the core compliance checks. That makes it useful for both shipboard and shore-side workflows.

An ad hoc check often confirms only that a few documents exist, while this template forces a repeatable review of completeness, retention, labeling, storage, and sign-off. That reduces the chance of missing a record because the reviewer forgot to check an older delivery or a sample cabinet. It also creates a cleaner audit trail when a deficiency needs follow-up.

Treat it as a traceability deficiency, because the sample may not be reliably linked to the delivery it represents. Record the missing fields, note the affected delivery if it can be identified, and assign corrective action to relabel, replace, or document the chain of custody as appropriate. If the sample cannot be tied back to the delivery, it should not be treated as fully compliant evidence.
