Draft Survey & Quantity Determination
Independent draft survey and cargo quantity determination for bulk agricultural shipments, verifying weight at loading and discharge.
Overview
Bulk agricultural cargo quantity can be disputed without an independent method to verify weight loaded or discharged. CARSURIN surveyors record vessel drafts, ballast, bunkers and water density before and after cargo operations, then calculate the change in displacement to determine cargo weight, supporting transparent quantity verification for both parties.
