Full title and description

Maritime navigation and radiocommunication equipment and systems - Bridge alert management - Part 1: Operational and performance requirements, methods of testing and required test results. This international standard specifies operational and performance requirements, test methods and required test results for bridge alert management (BAM) systems used to present and transfer alerts on the ship bridge to support safe bridge operations and reduce alarm overload.

Abstract

IEC 62923-1:2018 defines how alerts presented to and transferred across the ship bridge shall be handled: priority categorization, presentation and grouping, escalation and aggregation rules, audible and visual annunciation, HMI requirements for central alert management, interfacing behaviours and required test methods and results to demonstrate compliance with the BAM performance objectives (aligned with IMO MSC.302(87)). The standard is intended to improve situational awareness and reduce nuisance alerts through consistent operational rules and verifiable test procedures.

Scope

IEC 62923-1:2018 applies to all alerts presented on and transferred to the ship bridge. It specifies operational and performance requirements, methods of testing and the required test results for Bridge Alert Management (BAM) systems to ensure consistent alert presentation, handling, escalation and interfacing behaviour across bridge equipment and integrated systems. The standard is aligned with IMO resolution MSC.302(87) and covers alert states, priorities, aggregation, escalation, audible/visual annunciation, central alert management HMI requirements and documentation and test procedures.

Key topics and requirements

• Alert classification and priorities (emergency alarm, alarm, warning, caution) and alert states.
• Presentation rules for single and multiple locations, central alert management HMI, icons and text display conventions.
• Aggregation, clustering and escalation mechanisms to reduce nuisance alerts and present concise decision support.
• Audible annunciation, silence/acknowledge behavior and fallback/redundancy provisions.
• Interfacing requirements: transmission of priority/state/text, acknowledgement semantics, reconnection and degraded-mode behaviour.
• Defined test methods and required test results for presentation, performance, redundancy and interfacing (test setups, configurations and pass/fail criteria).
• Documentation requirements for system operation, testing and configuration.

Typical use and users

Used by ship designers, shipyards, system integrators, manufacturers of navigation and bridge equipment, software developers for integrated bridge systems, classification societies, flag administrations and ship operators (masters, watchkeeping officers). The standard is employed during product design, factory and harbour acceptance testing, type-approval activities and onboard installation and commissioning to verify BAM behaviour and interoperability.

FAQ

Q: What is this standard?

A: IEC 62923-1:2018 is an international standard that defines operational and performance requirements, plus test methods and required test results, for Bridge Alert Management (BAM) systems on the ship bridge.

Q: What does it cover?

A: It covers alert priorities and states, presentation and HMI rules, aggregation/clustering and escalation behavior, audible annunciation, interfacing semantics and required test procedures and results to demonstrate compliance with BAM objectives.

Q: Who typically uses it?

A: Shipbuilders, bridge-equipment manufacturers, integrators, software developers for navigational equipment, classification societies, flag states, and ship operators who implement or assess bridge alerting and integrated bridge systems.

Q: Is it current or superseded?

A: As published by IEC, IEC 62923-1:2018 is the first edition (2018) and is listed as the current IEC publication with a stability date shown to 2028; national/adopted versions (EN/ national) are also in force. Users should check national adoption notices or IEC corrigenda/amendments for updates.
