Draft Surveys
The purpose of draft survey is to determine the amount of cargo loaded or discharged. Draft survey is needed because of nature of bulk cargo
that can be determined only by the vessel's displacement before and after loading or discharging. The difference between these two displacements
it is the weight of the cargo loaded or discharged which is calculated using scales and hydrostatic tables and determination of other non-cargo elements such as: bunkers, fresh water, ballast, stores etc. Usually it is used at bulk cargo such as coal, grain, etc.
