Of course, you want to be sure that a boatmaster is in the vicinity of your terminal. Many terminals therefore require a boatmaster to do an announcement when he is no more than one or two hours away. The UAB-Online announcement time is then often used as the basis for the demurrage arrangements. Using the AIS module, you can easily see, with permission from the boatmaster, where the ship is currently located and where they were at the time of announcing.
In combination with our Geofence module, vessels may only do an announcement when they are located in a certain area around the terminal.
