OMC International (OMC) pioneered the use of high accuracy Differential GPS (DGPS) systems in the measurement of vessel motions. By placing three DGPS receivers on the vessel, horizontal and vertical vessel motions can be determined to sub-decimetre accuracy, at one second intervals. FSVMA studies are invaluable in quantifying actual UKC requirements and calibrating OMC’s Dynamic Under Keel Clearance (DUKC®) system models.

To date, OMC has carried out measurements on more than 220 vessels throughout Australia, New Zealand, Europe and the USA. These have included all major vessel types with varying depth/draft ratios, stability characteristics and transit speeds, channel configurations, tidal patterns and wave climates.

FSVMA techniques have also been applied to moored vessels to determine actual motions at berth, over long time periods.
