| The purpose of a bridge navigational watch alarm system(BNWAS)is to monitor bridge activity and detect operator disability which could lead to marine addidents.The system monitors the awareness of the Officer of the Watch(OOW)and automatically alerts the Captain or another qualified OOW if for any reason the OOW becomes incapable of performing the OOW鈥檚 duties. This purpose is achieved by a series of indications and alarms to alert first the OOW and, if he is not responding, then to alert the Captain or another qualified OOW.Additionally,the BNWAS may provide the OOW with a means of calling for immediate assistance if required. The BNWAS should be operational whenever the ship鈥檚 heading or track control system is engaged, unless inhibited by the Captain. | |
