A draught survey is one of the most common methods used for determining the quantity of cargo loaded onto a vessel, based on the Principle of Archimedes. This survey is typically conducted to ascertain the Bill of Lading weight. The parties involved in a draught survey usually include the Shipper, Receiver, Ship Owners, Charterer, and Terminal.
The accuracy of a draught survey depends on several well-documented factors, such as the precision of hydrostatic tables, weather and sea state conditions, and variations in the density of ballast water or sea water. However, one of the most critical factors is the expertise of the personnel conducting the survey.
