Bunker Quantity Survey

Independent determination of the fuel quantity supplied or transferred during a bunkering operation.

What risk it prevents

Fuel is often a vessel's largest operating cost

An unverified difference between what was invoiced and what was actually delivered translates into direct overcosts and disputes that are difficult to support once the operation is over.
