Alerts & Notifications

A lot of events occur in a harbour or during the port approach, events that cannot be monitored continuously. Valuable time is spent on keeping track of those events, by consulting the information sources such as internet.
If you recognize this situation, Royal Dirkzwager´s Alert & Notifications service is just what you need.


Royal Dirkzwager offers an alert service which provides notifications by e-mail, SMS text messages and XML file messages for certain events based on AIS information. You can receive an alert for vessels entering or leaving a specific area, vessels passing a virtual line, vessels entering or leaving a port, when a pilot is boarding the vessel etc.
These notifications can be sent one-time-only, within a certain timeframe or repetitive. The notifications can be sent to an individual addressee, multiple addressees, to computer systems or a combination of those. In the near future, you will have the possibility to maintain the parameters for sending these notifications (addresses, areas, vessels) yourself.


  • Reducing time and money spent on actively and continuously searching possible events.

  • Receiving automatic notifications about your fleet of vessels.
