SELMA developed and presents Bridge Inspector BNWAS
BNWAS – Bridge Navigational Watch Alarm System
Bridge Inspector is marine type approved according to the following latest rules, regulation and standards:
- IMO Resolution MSC.128(75) “Performance Standards for Bridge Navigational Watch Alarm System BNWAS”
- IMO A.694(17)
- IMO MSC.282(86)
- SOLAS 74 Regulation V/19
- IEC 61162
- IEC 60945
- IEC 62288
- IEC 62616:2010
Bridge Inspector monitors watch officer’s awareness for early detection of emergency.
BNWAS Bridge Navigational Watch Alarm System main objective is to monitor the activity in Wheelhouse and identify any disability of operator which could cause marine accidents.
In particular BNWAS monitors the awareness of 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. Consequently a sequence of warning, indications and alarms alert first the OOW and if he is not responding then alert the Master or another qualified OOW.
Additional the BNWAS may provide the OOW with a means of performing Emergency Calling for immediate assistance if it is demanded.
It is important to be noted that the BNWAS should be operational whenever the Ship’s Heading or Track Control System is engaged and generates valid NMEA 0183 Signal according to IEC 61162, unless inhibited by the Master.
