What is a "Bridge Navigational Watch Alarm System" (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).
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."
The BNWAS should be operational whenever the ship's heading or tracking control system is engaged.
BNWAS requirements and IMO regulations
The International Maritime Organisation, IMO, recognize (Resolution MSC.128(75)) that many operational bridge-related marine accidents could be averted if an effective and operational Bridge Navigational Watch Alarm System BNWAS was fitted to vessels.
IMO recognize further that, by the use of a Bridge Navigational Watch Alarm System (BNWAS) warnings will be given in case of the incapacity of the watchkeeping officer due to accident, sickness or in the event of a security breach, e.g. piracy and/or hijacking.
IMO is noting that the installation of such equipment is a relatively low-cost and an effective means of avoiding operational navigational accidents.
