Hawiyah Gas Plant Alarm Rationalization and Controller Performance Monitoring

In order to improve the plant and operation efficiency and reliability, HGP established a consistent and standard methodology for the development, implementation, and modification of process and system alarms. In addition, this methodology serves as guideline to monitor, fix and report bad actors in alarms and PID controllers. The task involves a comprehensive study to the entire plant alarms database including settings, grouping, priorities, philosophy and configuration. In addition, this task will ensure the continuity of PID controllers monitoring to ensure that all of the plant PID controllers are in auto and they are maintaining their set point. Succeeding to achieve this will ensure the optimum performance and efficiency and ensure more vigilant operation. HGP succeeded to bring the controller in auto to above 90% and a full alarms rationalization study was conducted to bring the alarms level to the international KPIs. The paper will start with providing basic background about essential definition including the alarms, alarm rationalization and controller performance monitoring. Thin, the paper will address the importance of the subject and the need of the improvement. As there are many recent studies indicates that missing critical alarms lead to fatal insidents and major damages to different facilities. In addition, many of the plants upset and changes could have been avoided if good alarming system is in place. Beside all of this, the paper will address the importance of the plant controllers’ automation as having these valves on auto will assure having the targeted product with the best possible efficiency.
