Draft Survey
Overview
An independent survey to determine the quantity of cargo loaded or discharged by measuring the vessel's displacement through accurate draft readings and relevant vessel data.
Benefits
Provides an accurate and independent determination of cargo quantity, minimizes quantity disputes, and supports reliable cargo documentation and commercial settlement.
Scope
Initial and final draft readings, vessel hydrostatic data, ballast and freshwater quantities, fuel and other relevant tank contents, seawater density, constant determination, displacement calculations, and cargo quantity calculation.
Process
Attend the vessel, record draft readings, verify tank quantities and vessel data, determine water density, calculate displacement and corrections, establish the cargo quantity, reconcile the results, and issue the Draft Survey Report.
