Bridge Alert Management (BAM)

Bridge alert management (BAM) is an overall concept to enhance the handling,
distribution and presentation of alerts on the bridge in a consistent manner.
This concept is described in the IMO performance standard "MSC.302(87) Performance
standard for Bridge Alert Management". Equipment related details are defined in other
equipment related performance and test standards.
The objective of BAM is to harmonize the priority, classification, handling, distribution and
presentation of alerts, to enable the bridge team to devote full attention to the safe
operation of the ship and to immediately identify any alert situation requiring attention
and/or action to maintain the safe operation of the ship.
Unnecessary distraction of the bridge team by redundant and superfluous audible and
visual alert announcements should be avoided. It reduces the cognitive workload of the
operator by minimizing the information presented which is necessary to draw attention to
and to assess the situation.
On the bridge alerts are presented on the individual equipment and/or on a central alert
management human machine interface (CAM-HMI).
Alerts are divided in different priorities:
• Emergency alarm*
Highest priority of an alert. Alarms which indicate immediate danger to human life or
to the ship and its machinery exists and that immediate action must be taken.
• Alarm
An alarm is a high-priority alert. Conditions requiring immediate attention and action
by the bridge team to avoid any kind of hazardous situation and to maintain the safe
operation of the ship.
• Warning
Conditions or situations which require immediate attention for precautionary
reasons, to make the bridge team aware of conditions which are not immediately
hazardous, but may become so. (Warning may be escalated to alarm)
• Caution
Lowest priority of an alert. Awareness of a condition which still requires attention out
of the ordinary consideration of the situation or of given information.
* The emergency alarm is not used in this device.
