Daniamant Electronics A/S - BNWAS BW-800

Consilium's Daniamant Electronics A/S BNWAS monitors the bridge activity and detects irregularities and operator disability. The BNWAS is developed in accordance to IMO MSC 128(75) and in compliance with IEC 62616 and MED.

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 Master if for any reason the OOW becomes incapable of performing his duties.

This bridge surveillance is achieved by an elaborate series of indications and alarms to alert first the OOW and, if he is not responding, then to alert another senior officer 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.
