Key takeaways
- Label each ROB figure by product and time.
- Distinguish measured quantities from calculated forecasts.
Reconcile the fuel movement record
An opening ROB, recorded receipts and estimated consumption can explain an expected closing balance. A measured closing quantity may differ, prompting review of the inputs and measurement basis rather than an immediate accusation of loss.
- Separate each fuel grade and identify the opening record.
- Log receipts, consumption and relevant transfers consistently.
- Compare the closing figure with its supporting measurement or calculation.
At a charter handover, make clear which figures are proposed, surveyed or agreed. A provisional balance used for voyage planning should not quietly become the final settlement quantity.
Common mistakes
Avoid combining different fuel grades under a single unlabelled number. Do not copy an old ROB forward without accounting for subsequent activity. Do not present calculated remaining fuel as a fresh physical measurement.

Frequently asked questions
Does ROB always mean fuel?
Fuel is a common use; identify the material explicitly in the record.
Why does the timestamp matter?
Consumption, delivery and transfers can change the quantity between observations.
Are estimated and measured ROB interchangeable?
No. Their different bases should remain visible to the reader.
How should a reconciliation difference be handled?
Investigate the inputs, timing and measurement records through the appropriate technical process.
