1 ABOUT BNWAS
The purpose of a bridge navigational watch system is to monitor the bridge activity and detect
operator disability which could lead to marine accidents. The system monitors awareness of the Watch
officer and automatically alerts the Master or another qualified person if for any reason watch officer
becomes incapable of performing watch officer’s duties. This purpose is achieved by series of indications
and alarm to alert first the watch officer and, if he is not responding, then to alert Master or another
qualified person. Additionally, the BNWAS provide the watch officer with means of calling for immediate
assistance if required. BNWAS must operate whenever heading or track control system is interlocking
unless prohibited by the captain.
