Introduction

Intuitive has developed a platform-independent alarm analysis toolkit designed to reduce the number of nuisance alarms displayed by a process automation system, give real-time process advisories and online cause-effect analysis. It enables:

• tuning of alarm systems by shift or team leaders
• decision support using expert systems to assist operators
• monitoring, analysis and tracking of alarms
• evaluation of operating procedures, alarm response times
• evaluation and subsequent configuration of alarms to maximise effectiveness

Why is alarm management important?

Recent research indicates that it is not possible for an operator to monitor more than 7 alarm events at any one time. When this limit is exceeded the resulting information overflow drastically increases the probability of an important alarm or event going unobserved. The possible consequences of this include personal injury, damage to or destruction of operating facilities, damage to the environment and potentially dangerous effects on the quality of the product.

Key Benefits of Alarm Analysis

The key benefits of Intuitive's Alarm Analysis toolkit are:

• Reducing operator workload by removing nuisance alarms
• Reducing effort required to manage alarms and events
• System analysis improving compliance with relevant regulations
• Creating effect alarms to reduce system downtime i.e. decreased mean time between failures (MTBF)
• Increased ability to diagnose plant accidents or incidents
