The purpose

The purpose of a BNWAS Bridge Navigational Watch Alarm System is to monitor bridge activity and detect operator disability which could lead to accidents. The system monitors the awareness of the Officer of the Watch (OOW) and automatically alerts another qualified OOW or the Captain if for any reason the OOW becomes incapable of performing the OOW’s 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 another qualified OOW or the Captain. 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’s heading or track control system is engaged, unless inhibited by the Captain.

  • Wheel Mark
  • IEC 62616 (New standard from February 2010)
  • IMO MSC. 128(75) (Old recommandation from May 2002)
