The bridge navigational watch alarm system (BNWAS) monitors bridge activity and detects operator disability that could lead to marine accidents.
The system monitors the awareness of the Officer Of the Watch (OOW) and automatically alerts the Master or another qualified person if for any reason the OOW becomes incapable of performing the OOW’s duties.
This process is subdivided in different alarm stages which primarily try to alert the OOW via visual and audible alerts.
