AMI Marine BNWAS-150 Bridge Navigational Watch Alarm System (BNWAS)
Product Overview
The AMI Marine BNWAS-150 Bridge Navigational Watch Alarm System (BNWAS) is an IMO-compliant bridge safety system designed to continuously monitor the activity of the Officer of the Watch (OOW). If no operator activity is detected within the configured period, the system automatically initiates a sequence of visual and audible alarms, followed by alerts to backup officers and designated crew members. The BNWAS-150 enhances bridge safety, reduces the risk of human error, and complies with international SOLAS carriage requirements. Professionally tested and reconditioned units are available from WAVETECH MARITIME.

The AMI Marine BNWAS-150 Bridge Navigational Watch Alarm System is a professional marine safety system developed to ensure continuous bridge watchkeeping in accordance with IMO SOLAS requirements. The system supervises the Officer of the Watch (OOW) by monitoring bridge activity and automatically generating escalating alarms if the officer becomes incapacitated or fails to acknowledge the system within the preset interval.
The BNWAS-150 operates through a multi-stage alarm sequence. Initially, visual and audible alarms are activated on the bridge. If there is still no acknowledgement, alarms are automatically transferred to the Master's cabin or designated backup officers. A final alarm stage activates additional audible alarms in public or operational areas to ensure immediate crew response.
The system typically consists of:
- BNWAS Control Unit
- Reset Units
- Motion Sensors
- Alarm Sounders
- Connecting Modules
- NMEA Interface Module (where installed)
- Emergency Call Function
- External Alarm Outputs
The BNWAS-150 integrates with modern bridge equipment including:
- Autopilot Systems
- ECDIS
- Voyage Data Recorder (VDR)
- Integrated Bridge Systems (IBS)
- Bridge Alarm Management Systems
- NMEA Navigation Equipment
Designed for continuous operation in harsh marine environments, the system offers configurable alarm intervals, bridge activity monitoring, emergency call functionality, and simple user operation. It is widely installed on:
- Cargo Ships
- Container Vessels
- Bulk Carriers
- Oil & Chemical Tankers
- LNG & LPG Carriers
- Offshore Support Vessels
- Passenger Ships
- Naval Vessels
- Research Vessels
