The calculation method of the probability that a ship traveling to the harbor touches the bottom.
The calculation method determines the probability that a ship, going through a channel with a certain speed at a certain time and location, hits the bottom. This calculation is repeated a lot of times while varying the possible circumstances (weather, water and ship dynamics). The times and locations where the probability of hitting the bottom is smaller than a prescribed safety criterion are suitable for a navigational route. For a detailed description of calculating safe time segments and the formal calculation of the bottom touch probability view the specific sections under calculation components:
