What Is a Bunker Survey?
A bunker survey is an independent inspection conducted before, during and after a marine fuel transfer operation.
The purpose of a bunker survey is to accurately determine the quantity of fuel delivered to a vessel and verify that the amount supplied corresponds with contractual agreements and delivery documentation.
The survey process typically involves:
Measuring fuel tank levels
Calculating fuel volumes
Verifying fuel transfer quantities
Reviewing bunker delivery notes
Monitoring transfer procedures
Recording relevant operational data
Accurate bunker surveys provide transparency and help protect all parties involved in the fuel supply process.
Given the significant value of marine fuel transactions, even small discrepancies can result in substantial financial losses.
Independent bunker surveys provide an additional level of assurance and accountability during fuel transfer operations.
