BNWAS stands for “Bridge Navigational Watch Alarm System.” It is a safety system used on ships and vessels to monitor the presence and alertness of the officer or crew responsible for navigation on the bridge. The primary purpose of the BNWAS is to enhance maritime safety by ensuring that there is always a vigilant watchkeeper on the bridge, especially during long or monotonous voyages.
The BNWAS is a crucial safety measure in the maritime industry, as it helps prevent accidents resulting from a lack of vigilance on the bridge, which can occur due to factors like fatigue, distraction, or monotony during long voyages. Regulations from organizations like the International Maritime Organization (IMO) require the installation of BNWAS on certain types of vessels to ensure compliance with safety standards and prevent navigational accidents.
