DUKC is a method of using multiple prediction and real time factors to determine the draft limitations on ships.
The DUKC system integrates real-time measurement of tide height and waves with modelled vessel motions in order to determine if a proposed transit for a particular vessel meets pre-determined under keel clearance safety criteria.
By dynamically modelling each UKC component and then adding an additional safety allowance; DUKC transits achieve an accuracy and safety that far exceed traditional static rules that assume fixed allowances from which UKC components must be accounted for.
DUKC models are specifically configured and validated based on full-scale measurements at the port, and comply with international standards for safety of navigation in shallow waterways.
