Our follow up research on alarm management in the maritime industry examines just over 2,000 days, or ~48,000 hours, or no fewer than 40 million unique alarm-related events from the integrated automation systems of 11 participating ships, through the lens of the widely recognised performance targets found within IEC 62682:2014 and EEMUA 191.

Our comprehensive quantitative research confirms what the watchkeeping officers have been experienced, as presented in our previous work:
- there were too many alarms during upsets,
- an overwhelming number of nuisance alarms with little operational value
In light of these findings, we encourage the maritime industry to adopt policies to evaluate their alarm systems objectively and to begin as soon as possible.
