Maritime crews globally are grappling with alarm systems that overwhelm them with thousands of alerts daily, leading to what is known as ‘alarm fatigue.’ This issue can transform critical operations into a strenuous fight against constant distractions. Recent research, part of LR’s Digital Transformation Research Programme, builds on insights from 65 active watchkeepers and their real-world observations on bridges and in Engine Control Rooms (ECRs).
The follow-up study offers a quantitative analysis of alarm behavior, examining over 40 million alarm events across 11 vessels. By utilizing established industrial standards and incorporating onboard observations, the report highlights a concerning trend: current alarm systems often exceed human capacity. This overload not only disrupts crew rest but also diminishes trust in the systems designed to ensure safety.
However, the findings also present a silver lining. The research demonstrates that significant improvements to alarm systems are both practical and attainable. With modest, engineering-led interventions, maritime operations can enhance crew well-being and operational efficiency. This study underscores the urgent need for reform in alarm management to support the safety and effectiveness of maritime crews.
