Bridge Alert Management (BAM)


Bridge Alert Management (BAM) helps to improve the handling, forwarding and presentation of alerts

Bridge Alert Management (BAM) helps to improve the handling, forwarding and presentation of alerts. In doing so, it harmonises the priority, classification, handling, distribution and presentation of alerts, meaning that the bridge team can devote its full attention to the safe operation of the ship and immediately identify any alert situation requiring action to maintain the safe operation of the ship.

The IMO recommends the use of bridge alert management systems to governments for those ships flying their flags. BAM installed on bridges should at least conform to the performance requirements stated in the annex to IMO Resolution MSC.302(87).

In principle, the following should apply:

  • BAM is encouraged by the IMO and is being implemented in Germany as such to begin with.

  • “Requirements” in the IMO performance standards are, in principle, given priority over specifications in the testing standards, even if the latter came into force beforehand (see also: VDR). The document should make reference to whether the “new” or “old” requirements are met.
    (This also applies in view of the fact that the draft revision of the MED no longer provides a clause that testing standards are to be used in their up-to-date version)

Specifically, this means that:

  1. After the performance standard has come into force, a BAM (Module BAM-HMI) must be type approved but is not required for mandatory carriage according to the SOLAS V/18. However, it is recommended that the vessel is equipped with a BAM system. Exception: An Alert Management system (AM) is included in the INS performance standard.
    If BAM and INS are installed, Alert Information must be integrated into Central Alert Management (CAM)/Human Machine Interface (HMI).

  2. The BAM performance standard modules effective for all systems (cross-sectional modules A and C) are also only recommended for equipment to begin with. This shall also apply if the current testing standard for a single system (such as ECDIS, GYRO...) already contains the corresponding testing procedures for these modules (see above: IMO priority).

This rule shall apply as long as:

  • The IMO stipulates the implementation of BAM in general or in the individual performance standards in a binding manner or

  • The MED stipulates the BAM performance standard for every single device in a binding manner.

Ships are not required to carry BAM equipment. However, the Federal Maritime and Hydrographic Agency does recommend that the producers of individual systems implement the BAM function because it is sensible and it is to be expected that the MED will make implementation mandatory in any case.

Documents should either contain the indication that the device is not suitable for connection to a BAM system (if the BAM sections of the testing standard have not been implemented) or that the device is already suitable for connection to a BAM or INS system (if the BAM sections of the testing standard have been implemented, although it is not yet mandatory).
