New Regulation : Bridge Navigational Watch Alarm System (BNWAS)

BNWAS is a system to monitor wheelhouse activity and detect officer of the watch (OOW) disability which is could lead to marine accidents.

Sample of BNWAS 

How does it's work?


This system require OOW to press the button on a Timer Reset Panel or to prepare navigational equipment (e.g ECDIS, Radar, autopilot etc.) at certain intervals. If the OOW fails to press the button within pre-set intervals, visual and audible alarms will be generated in the wheelhouse. If the OOW doesn't respond to the alarm,the system transfers the alarm to the Cabin Panel installed in other sections of the vessel in order to inform backup officers of the watch officer's incapacity
