Case Study: a confidential global exporter of hydrocarbons reduces nuisance alarms by 99% with Audubon alarm management

a confidential global exporter of hydrocarbons cuts nuisance alarms by 99% with Audubon

A confidential global exporter of hydrocarbons faced a critical challenge at its Louisiana LNG export facility, where an overwhelming 120,000 nuisance alarms per day from its Yokogawa DCS compromised safety and overwhelmed operators. The company enlisted Audubon to resolve the alarm management issue and bring the system into compliance with regulatory standards.

Audubon implemented a multiphase alarm management solution that included a benchmark assessment, root cause analysis, and rationalization workshops. The team reconfigured the system with custom priorities and implemented delay timers to address chattering alarms. Audubon successfully reduced the alarm volume by 99% to just over 1,500 per day, a rate of just 6 per hour per console. This dramatic improvement enhanced safety, efficiency, and system reliability, and the project was completed ahead of schedule and under budget.
