Introduction of Bridge Navigational Watch Alarm System:

 

The purpose of a bridge navigational watch alarm system ( HABJ0001 BNWAS ) is to monitor bridge activity
and detect operator disability which could lead to marine accidents. The system monitors the awareness of the
Officer of the Watch ( 00W) and automatically alerts the Master or another qualified 00W if for any reason the 00W
becomes incapable of performing the 00W’ s duties. This purpose is achieved by a series of indications and alarms
to alert first the 00W and, if he is not responding, then to alert the Master or another qualified 00W. Additionally,
the BNWAS may provide the 00W with a means of calling for immediate assistance if required. The BNWAS should
be operational whenever the ship’s heading or track control system is engaged, unless inhibited by the Master.

 

This system meets the requirements of MSC. 128 (75),IEC62616(2010) and can be used in any kind of ship.
