This International Standard specifies the minimum performance requirements, technical
characteristics and methods of testing, and required test results, for a bridge navigational
watch alarm system (BNWAS) as required by Chapter V of the International Convention for
the Safety of Life at Sea (SOLAS), as amended. It takes account of the general requirements
given in IMO resolution A.694(17) and is associated with IEC 60945. When a requirement in
this International Standard is different from IEC 60945, the requirement in this standard takes
precedence.
This standard incorporates the parts of the performance standards included in IMO resolution
MSC.128(75).
(128/A1) The purpose of a 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 is underway at
sea (SOLAS V/19.2.2.3).
