Frequently Asked Questions
What is a Bunker Quantity Survey?
An independent measurement of bunker fuel quantity before and after delivery, using sounding and calculation to verify the volume actually received against the delivery figures presented.
How is this different from a full Bunker Survey?
A Bunker Survey covers both quantity and quality, together with a broader review of delivery documentation. A Bunker Quantity Survey is narrower — it focuses specifically on the before-and-after sounding and measurement needed to confirm received volume, for cases where quantity is the concern rather than the full survey scope.
When would a charterer or shipowner request this instead of a full bunker survey?
Typically when quality is not in question and the priority is a straightforward, independent check on quantity received — for example when reconciling delivery figures or addressing a suspected shortfall.
What does the survey involve?
Tank soundings and measurements taken before delivery begins and again once delivery is complete, with the resulting figures calculated and compared against the delivery quantity claimed.
How quickly can a Bunker Quantity Survey be arranged?
For vessels calling Mersin, Adana, or İskenderun, attendance can typically be arranged on short notice; for wider Türkiye-based assignments, timing is subject to scope and schedule.
