At a bulk export port, the port authority aims to maximise cargo throughput at the port while maintaining safety. One key aspect of safety is restrictions on ship draft. Draft is the distance between the waterline and the bottom of the ship’s keel, which increases as more cargo is loaded. Most ports have restrictions on maximum draft for ships entering andleaving the port, as loading a ship beyond the safe draft limit may result in the ship running aground.

DUKC® Optimiser is a new tool that aims to simplify scheduling of ship sailing times and drafts for bulk export ports that use DUKC® software to calculate draft restrictions. DUKC® Optimiser also aims to find optimal schedules that allow ships to carry more cargo than schedules produced by human schedulers.
