Bridge Navigational Watch Alarm Systems (BNWAS) play a critical role in maintaining crew vigilance and overall bridge safety by actively monitoring officer activity and alertness during watchkeeping duties. When inactivity or unresponsiveness is detected, BNWAS issues escalating audible and visual alarms to prompt immediate action. This functionality ensures strict compliance with internationally recognized watchkeeping standards and minimizes risks associated with operator fatigue or human error.
