2008 - Gas onshore processing
As part of a major plant design, Andy's client was required to carry out an alarm review. Andy advised the control, process and operations engineers on the project of current good practices for process alarms, particularly regarding prioritisation, and assisted in the initial review. They commented that this would result in an alarm system that was quite different to those they had experienced in the past but quickly understood the logic and started to see the benefits.
The end result was a relatively small number of high priority alarms, with more medium and low priorities, and a significant number assigned to 'journal.' This compared to an initial allocation where the vast majority of alarms were to be assigned high priority, which would have inevitably resulted in a high workload and distraction for operators. Although a significant undertaking, the project proved that an alarm review was achievable and manageable.
