BNWAS is a shortcut for 'Bridge Navigational Watch Alarm System'.
The Bridge Navigational Watch Alarm System (BNWAS) is a safety system that is used on ships to alert the bridge team when there is a risk of collision or other navigational hazard. The BNWAS consists of a number of sensors and alarms that are connected to the ship's navigation equipment and that are designed to detect when the ship is in danger of colliding with another vessel or object, or when there is some other navigational hazard that requires attention.
When the BNWAS detects a potential hazard, it sounds an alarm and displays a warning on the ship's navigation equipment. This alert is designed to draw the attention of the bridge team to the potential hazard and to prompt them to take appropriate action to avoid the collision or other hazard.
The BNWAS is an important safety feature on ships, as it helps to ensure that the bridge team is aware of potential hazards and can take timely action to avoid them.
