New Bridge Alert Management (BAM) requirements are now in force

From 29 August 2021, navigation- and radio-communication equipment to be installed on board vessels is required to be compliant with Bridge Alert Management (BAM) according to IEC 62923-1 and 2 under the EU Marine Equipment Directive (MED). This statutory news summarizes the BAM regulations.

New bridge alert management (BAM) requirements are now in force

Relevant for manufacturers of navigational equipment on European flagged vessels.

Bridge Alert Management (BAM) is required for navigationand radio-communication equipment installed after 29 August 2021. BAM is applicable for navigation- and radio-communication equipment that can raise or present alerts on the bridge.

Navigation- and radio-communication equipment to be installed on EU (incl. EEA) ships after 29 August 2021 should include the IEC 62923-1 and -2 standards on BAM within the scope of the MED certificates.

The IEC 62923-1 and -2 standards on BAM were published in 2018 and added to the list of applicable testing standards for most navigation- and radio-communication equipment in the third Implementing Regulation (EU) 2019/1397, which was published in September 2019. The last date for installation of equipment on board an EU ship that has not been tested for compliance to the BAM standards was 29 August 2021. Manufacturers have hence had a period of approximately two years to update their products to comply with the requirements.


From 29 August 2021, Module B certificates for navigationand radio-communication equipment to be installed on EU (incl. EEA) ships should address the IEC 62923-1 (2018) and IEC 62923-2 (2018) testing standards within their scope.

Manufacturers need to have valid MED certification (Modules B+D, B+E, B+F or G certificates) to be permitted to place their products on the European market.

Note that the expiry date of the certificate may be overruled by changes introduced in Implementing Regulations published after the issuance of the certificate.

Please see the latest Implementing Regulation for the applicable requirements for the equipment when evaluating the validity of MED certificates. This is available on the DNV website at

A re-assessment may be necessary. Please contact your local DNV office for initiation of the process of revising the certificate.

IMO Maritime Safety Committee (MSC 104)

The 104th session of the IMO’s Maritime Safety Committee (MSC) was held remotely from 4 to 8 October. The requirements for watertight doors on cargo ships were harmonized, and the Japanese Quasi-Zenith Satellite System was recognized for the provision of position, navigation, and timing services. The MSC also initiated the development of a goal-based instrument for autonomous ships, and the development of guidance for remote surveys and audits.
