Bridge Navigational Watch Alarm System

DMA-105 Control Unit

Bridge Navigational Watch Alarm System (BNWAS) is 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.

Seab Marine has produced its own BNWAS system called DMA since early 1990. This new version is a very much improved version of the previous one.

If you do not have enough space under the pulpit, you can save both space and time with the newly developed steel cabinet DMA-118.

Seab Marine AB is one of the world's leading suppliers of certified BNWAS systems and certified by DNV.
