Introduction
The ease at which Distributed Control Systems (DCS) alarms can be created has removed the incentive to limit the number of such alarms. The result, operators today are potentially faced with more alarms than they can effectively monitor. Alarm Systems Management (ASM) should, therefore, identify unnecessary alarms, those set at the wrong value and general overall improvement to the systems and procedures
Poor management and poor ownership of alarm systems with no agreed alarms policy inevitably lead to a situation where alarms are incorrectly set giving large numbers of irrelevant alarms which the operator, frustrated, begins to ignore or which may obscure more critical alarms. Rationalization and de-manning of control rooms without an awareness of human factors further increases potential risks. In this ‘nontechnically’ based seminar you will learn how to:
Apply concepts and procedures for improving alarm management
Assess the performance of your system with a range of improvement techniques
How to improve and apply Alarm Management techniques
Evaluate your current operator readiness, state of training and ability
Consider the opportunities for increased plant performance and safety
Course Objectives of Alarm Management
- Alarm Management will provide you with a collection of techniques, tools, standards, and procedures that will improve operations and overall effectiveness
- Business Case Tools: Understand the costs of poor alarm performance or not implementing an alarm management philosophy by reviewing sample business case studies
- Best Practice Alarm Management Strategies: Quickly and effectively integrate alarm management strategies by examining successful, working solutions
- Alarm Management Performance: Understand the number of ways of measuring the performance of an alarm system and its users
- Ensuring that Emergency Response systems are in place so if/when the system does fail the response can be efficient and effective
Course Methodology of Alarm Management
Delegates will be encouraged to fully participate in this non-technical program through the use of syndicate workshops and presentations, group discussions, and questionnaires. A hard-copy manual (and CD), PowerPoint slides, relevant DVD material, handouts, and case-studies will be fully utilized
Organizational Impact of Alarm Management
The many shortcomings found in alarm systems can cause incidents where the risk to personnel is increased together with an increase in operating costs. Participants will be introduced to concepts, methods, and procedures for dealing with alarm management systems
- Configured and correctly enforced, alarms need to be set at the right operating conditions
- Identify possible causes for the alarm whether it’s legitimate (providing the information), spurious (misleading or a nuisance) or redundant (telling the operator something he already knows)
- Such conditions will be a major tool allowing process operators to rapidly identify escalating abnormal situations and take action to recover
- Avoid abnormal situations that can quickly lead to personnel danger, environmental issues, commercial loss and a damaged reputation.
