BNWAS BW-800 is produced in Denmark to ensure the high level of quality is maintained. BW-800 is designed as a cost effective product and it is easy to install which means low installation costs for the vessel owner.
The small size of the units makes it easy to install on vessels with limited space for new equipment. Most of the systems are installed as retrofit when the vessel is sailing from one port to another or installed the next time the vessel is in dock.
Normally, it is more cost effective to exchange an old dead man alarm with a new BNWAS than trying to upgrade the old system.

Why install BNWAS?
Regulations from IMO’s Maritime Safety Committee (MSC) requires carriage of a BNWAS Bridge Navigational Watch Alarm System complying with IMO performance standards.
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 Captain or another qualified OOW if for any reason the OOW becomes incapable of performing the OOW’s duties.
