What is BNWAS?
The term BNWAS is an acronym for the term Bridge Navigational Watch Alarm System - a safety system made mandatory in amendments to SOLAS Chapter V Regulation 19 and adopted on 5th June 2009 by Resolution MSC.282(86).
Why Do You Need a BNWAS?
As outlined in the performance standards MSC.128(75):
"The purpose of the bridge navigational watch alarm system (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 (OOW) and automatically alerts the Master or another qualified OOW 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 the Master 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's heading or track control system is engaged, unless inhibited by the Master."
