It includes a geographical information system, a marine casualty information system, and electronic charts.
Analysts can now use the MNSS to estimate the risks in waterways for any ship type.
The estimated track width provides safe passage for 99.9 percent of vessels. Background TDC's work towards this safety system began in the early nineties. Researchers developed the original data base through studies on the MV Arctic , an icebreaking oil, bulk, and ore carrier. Trials of the parent version of the system led to recommendations for further development to make it more robust and to extend its capacities. A recent risk analysis project in Canso Strait allowed for modification and enhancement of the original risk model.
