KONGSBERG BWMS Bridge Watch Monitoring System

KONGSBERG BWMS Bridge Monitoring System

System Overview

KONGSBERG BWMS is a bridge duty safety monitoring system used to monitor the status of the bridge duty, and to raise alarms step by step when there is no one/disabled.

Complies with IMO MCS.128 (75) BNWAS performance standards and meets the requirements of single person bridge operation class symbols.

Adopting standard modules and software to adapt to all ship types.

Core functions

Centralized alarm: The central panel of the driver's cab provides sound and light alarms and receives signals from the core navigation equipment on the cab.

On duty monitoring: detect unmanned or disabled operators on the bridge at regular intervals.

Automatic alarm forwarding: When the bridge alarm does not respond, the alarm will be automatically sent to the captain's cabin, public areas, and crew cabins.

Manual alarm forwarding: The alarm can be manually triggered to call the captain and backup duty personnel.
