Our surveys

Bunker supply quantity and quality surveys:

Considering the present excessive bunker oil prices, we deem this type of survey absolutely necessary, in order to make sure that the quantities as mentioned on the Bunker Delivery Notes (BDN) are true and correct.

Before and after bunkering our surveyors sound/calculate the contents of the cargo tanks of the delivering tank barge, taking the actual temperature of the oil into consideration.

The difference between the contents before and after bunkering is the exact quantity of oil supplied to the sea going vessel and must be in line with the supplied quantity as mentioned on the BDN.

However, there still are ship owners/operators and charterers who leave the above procedure to the chief engineer in order to save survey costs.

In this respect we wish to emphasize that in such a case the chief engineer often ends up with an incorrect supplied quantity (mostly to his disadvantage), since he is not familiar with the barge’s cargo tank calibration scales in the Dutch language, the “manner” of sounding of the barge’s crew and -last but not least- the amount of unpumpable oil in the cargo tanks of the barge after bunkering.
