Andy acted as leader of an alarm review for two new gas turbines. He ran a workshop attended by representatives from operations, engineering, projects and maintenance teams; as well as EPC contractors and vendors. Andy's first task was to achieve an agreed alarm philosophy consistent with latest standards and guidance including EMMUA 191. This was then applied to the proposed set of alarms for the turbines and associated systems. The result was a significant reduction, with approximately 70% being converted to journal notifications that would be recorded but not create an audible alarm in the control room. This approach allowed fundamental changes in the way the turbines were to be operated where the operators could concentrate on proactive monitoring of the plant whilst the maintenance department would be responsible for identifying and planning maintenance interventions. As well as specifying improved alarms, Andy's report made recommendations for improved process graphics and performance reporting.
