TECHNOLOGICAL INNOVATIONS APPLIED TO THE DRAFT SURVEY PROCESS FERNANDO ARAÚJO DOMINGUES, ALVARO CAMARGO PRADO

Abstract

The Draft Survey is necessary for the loading and unloading of waterway cargo, ensuring weight accuracy and avoiding losses. The draft survey, which measures the vessel's draft before and after loading, is essential, but time-consuming and subject to inaccuracies, resulting in delays and financial losses. This work aims to identify how technology can reduce the time and improve the accuracy of the draft survey. It also addresses innovative models applied in other ports. The research used bibliographic sources, legislation and scientific articles. The draft survey is widely used in dry bulk ports, such as the Port of Santos, where the process takes around an hour, causing delays and losses. Weather conditions can affect loads and cause discrepancies between the declared load and the calculated load, resulting in losses and longer dwell times. The work highlights the need for technology in busy ports to reduce shipping times and avoid economic disputes. The port and scientific community must develop economic methods, processes and devices to improve the draft survey. Many sources cited are from Eastern researchers, focused on improving port operations.
