Draft Survey Tool

The Draft Survey Tool (DST) and DST Lite, both SGS inventions, use the latest technology to help address the need for accuracy in cargo weight. They record data digitally and save draft readings to the cloud (DST) or an app (DST lite).

Both tools use an algorithm that enables an accuracy rate to within 2mm in 30m. Regardless of the amount of space available on a vessel or barge to take a reading, you can use one of these tools to determine cargo weight and manage the cost of your fertilizer shipment.
