Under-Keel Clearance Manager

UKC Manager™ is a Windows-based software application for predicting reduction in under-keel clearance (UKC) and safe ship speed prior to entering shallow waters and confined channels. It is designed to be used by the ship officers (and pilots) as part of their passage planning procedures to optimize payload, estimating the tidal window, to ensure safe transit speed through UKC critical areas along a planned route and to provide UKC documentation to authorities and clients, e.g. for vetting inspections.


The software is based on well-accepted theories and methods in ship and marine technologies. Validation of the program is based on a scientific procedure (ITTC, 1990).
