Bunkering inspection or bunker survey is quantity inspection and quality inspection when supply bunker (FO and/or DO).
Quantitative inspection for Bunkering is gauged of all tanks of mother vessel and witnessed regardless of whether or not they are delivery tanks as per vessel tank plan before and after delivery of the bunker…
Bunker requisition form will be filled up by vessel and barge prior pumping of the bunker containing product name, grade, density , water content , flash point and sulphur content.
Bunkering sample will be collected at ship’s manifold during bunkering. This is compulsory as per IMO MARPOL. regulation.
Bunker samples will be divided and distributed as below:
– One sample for the vessel
– One MARPOL sample for the vessel’s retention
– One sample for the bunker tanker
– One sample for the bunker surveyor
– One sample for analysis (for the bunker surveyor), if the quality bunker inspection is required (If quality is not require, this sample need not be collected)
Testing parameters of bunker sample as below:
