BNWAS

PURPOSE OF BNWAS

        The purpose of a bridge navigational watch alarm system is to monitor bridge activity and detect operator disability which could lead to marine accidents.

        The system monitors 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 OOW duties.

This purpose is achieved by series of indications and alarm to alert first the OOW and, if he is not responding, then to alert Master or another qualified person.

OPERATIONAL MODES

The BNWAS should incorporate the following operational modes:

- Automatic (Automatically brought into operation whenever the ship’s heading or track control system is activated and inhibited when this system is not activated)

- Manual ON (In operation constantly)

- Manual OFF (Does not operate under any circumstances)
