Automatic Man-Over-Board Alarm System with GPS Positioning

B-AQUASAFE is an automatic man-over-board alarm system for the safety of personnel working at sea. The system relies on a water sensor which is attached to the radio terminal and fitted to the life jacket. For small isolated installations, the system can operate in DMO mode and when operating with a repeater a Central Alarm Unit can be integrated in the solution.

When the sensor is submerged in water, it automatically generates an alarm message which is transmitted to other terminals, stating the alarm type and the identity of the terminal issuing the alarm.


The Central Alarm Unit can receive water alarms from the entire radio network, dispatch the alarm as email or SMS alarm messages to defined PC’s and mobile smartphones. In addition, it can monitor the GPS position of the terminal generating the alarm which can greatly reduce rescue response time. It is also possible to display the GPS position of the device that triggers the alarm on a digital map.


The Alarm Unit can also run system checks to ensure that the B-AQUASAFE system works in accordance with specifications and thereby continuously protects the staff in the most safely way.
