DRAFT SURVEY

The Draft Survey basically Archimedes’ theory applied to calculate the weight of cargo during loading/ unloading in vessel from measurements of changes in its displacement.

We have got a very good experienced Marine Surveyor to accomplish draft surveys, as per clients’ requirements. We have acting different times on behalf of Owners, Charterers or any other interested party.

We have the quality of our services by using our own calibrated equipment like sounding tape, Paste, assure that measuring tape in good condition, no error, during sounding ballast tank as accurate as possible.

Our attending Marine Surveyor attend before berthing vessel jointly reading vessel’s initial draught marks with responsible officer. After draught reading, our attending Surveyor obtain samples of dock water in which the vessel is floating to make sure fresh water density as accurate as possible in order to obtain perfect quantity.

The total deductible weights on board and all draft marks readings are measured and calculated by us in accordance with data supplied by the vessel (hydrostatic and tanks calibration tables) prior to commencement of loading/discharging and on completion of loading/discharging. By using international guidelines, Vessel chief officer during discharging/loading keep changing ballast quantities to maintain good stability of the vessel. Observed consumption of vessel’s bunkers and fresh water, performing corrections proper corrections for trim, list and deflection (hog/sag).

After completion of inspection issue certificate of quantification by marine surveyor to acknowledge shippers and receivers’ complete data obtained from ship stability book and sounding book, Fresh water and bunker condition, as well as Hold washing tank if applicable.

During inspection all activities has been recorded for future reference.
