MOD@A™ (Man Overboard Detection @nd Alarm system) is a system designed by EsiWelma for the detection of persons falling overboard a ship during navigation.

The association of laser sensors, proprietary software and high resolution cameras was adopted in order to give the personnel on duty the possibility of being alerted, in case of a man overboard casualty, reviewing repeatedly the images of the event immediately before and after the alarm, and quickly deciding the manoeuvres to undertake.
