Abstract: Abstract:To effectively prevent vessels from grounding, this study uses Marine Geographic Information System (MGIS) to obtain 3D seabed topography and geology in order to build a novel virtual aid navigation model with a grounding alert. Dynamic and static data is provided by the automatic identification system as the input, and fuzzy logic control is used for output. The maximum draft point along the vessel route is configured as the reference point and a swath angle of 0°~90° is used to search the seabed topography segments and obtain the water depth swath angle (WDSA) by the concept from the compression and dilation equations for time and space. MGIS is used as the data processing platform. After comparing and analyzing the professional sailing rule base with the high alert rule base with regard to the security benefit of the hazard alert, an appropriate value for the alert distance is configured. Based on three alert levels (amber, red and flashing red/alarm), vessel traffic service operators and crewmembers can immediately obtain a clear warning. That is, vessels that can potentially become grounded can effectively avoid danger zones in advance.
