DRAFT SURVEY INSPECTION<\/h2>\n

Draft Survey<\/strong> is a widely applied method in the maritime industry to determine the weight of cargo loaded or discharged<\/strong> from a vessel by measuring the ship\u2019s draft before and after cargo operations. This method is essential in bulk cargo trade, ensuring transparency and accuracy in cargo quantity determination.<\/p>\n
