Alarm Rationalization for Improving Safety - An Application Example in Petrochemical Corporation of Singapore (Private) Limited

摘要

Proper alarming is critical for safe and stable plant operations. Along with the progress of control systems, alarms can be easily created for various conditions compared with the era when alarms were indicated and consolidated on a panel consisting of a series of annunciators. However, numerous nuisance alarms can overwhelm the operators. This report outlines Yokogawa's Alarm Rationalization and introduces an application example where nuisance alarms were reduced by 66% and safer and more stable plant operation was thus achieved.
