Alarm and safety system for ships
IMO Kongsberg Maritime

Our navigator safety system or "dead man alarm" is designed to monitor bridge activity and alert the master or other qualified navigators if the bridge becomes unattended. The system first alerts the officer of the watch through local alarm indication at the bridge unit and, if he is not responding, then alerts the master or other qualified officer.

Our navigator safety system conforms to the requirements of IMO resolution MCS.128(75) Performance standards for a Bridge Navigational Watch Alarm System (BNWAS) and the bridge class notations for "one-man bridge operation".
Purpose of a navigator safety system

Central bridge alarm panel provides visual and audible alarms and warnings. These are initiated by systems and individual navigation equipment serving primary bridge functions.
Bridge watch monitoring feature for detection of unattended bridge or operator disability based on interval checking.
Alarm transfer to specific locations outside the bridge to alert and call the master and back-up navigator(s), automatically initiated in case the bridge alarms are not attended to or an operator disability is detected.
Call back-up navigator for purpose of manual and instant initiation of alarm transfer from bridge for alert and call of master and back-up navigator(s).
