Draft Survey & Marine Services

Meet contractual requirements regarding cargo quantity with comprehensive draft survey solutions from SGS.

Failure to accurately calculate the quantity of an agricultural commodity cargo can result in contractual noncompliance, leading to inaccuracy of the declared quantity.

Quantity is measured by comparing the differences in the vessel’s displacement before and after loading or discharge. However, factors such as water density, ballast and on-board consumables are also considered in these calculations.
