1 Solutions for Optimizing Oil & Gas Operations Alarm Management Systems

2 Alarm Management Overview Alarms are an essential part of modern systems and the primary means of alerting operators of abnormal situations in their facilities. Even the best designed systems can become ineffective in the absence of alarms, resulting in potential human and financial setbacks. Research has shown that many process plants have improperly configured alarms that do not follow international guidelines and add to operators confusion. For an effective alarm system and smooth unobstructed plant operations, alarms need to be relevant, unique, timely, prioritized and understandable. Nearly all facilities with ineffective alarm systems show distinct symptoms of poor alarm system design. Symptoms of Poor Alarm System Design: A significant number of alarms are raised by minor issues Alarms remain active for very long periods of time There are no guidelines for alarm implementation Operators are unsure of how to respond to some alarms Processes run normally despite some alarms constantly going off Some alarms do not require an operator s response or attention Numerous alarms go off during routine operation but have no purpose A Need for Good Alarm Management Safety Poorly configured alarms risk the safety of: Plant, Personnel, Equipment Good alarms increase safety of all three by: Reducing unnecessary alarms Prioritizing important alarms Profitability Alarms not configured properly result in: Reduced production revenue Losses from damaged assets Properly configured alarms increase profitability by: Increasing uptime Decreasing incidental losses Human Factor Over 40% of incidents are caused by human factors Poorly configured alarms add to these risks Good alarms reduce errors from the human factor by facilitating operators

3 ISA 18.2 Compliant Alarms Management Life Cycle Philosophy A comprehensive document of work processes, sites and control systems along with best practices for alarm management. INTECH provides a unique customer-tailored Alarm Philosophy Document. Identification Data is collected for a baseline assessment of current alarm systems against standards, Bad Actor alarms are identified. INTECH analyzes data for 6-8 weeks and helps customers understand the cause of bad actors Rationalization Management of Change Areas of trouble in the alarm systems are identified and compared to the alarm philosophy document to evaluate a course of action. INTECH helps the site team understand, classify and prioritize alarms. Audit Design Alarms are re-engineered according to the alarm principles defined in the philosophy document. INTECH makes the Master Alarms Database (MADB) for the site. Implementation The re-engineered alarms are implemented and documented; relevant operators are trained how to respond to alarms. INTECH installs the MADB and performance management tools; also trains operators. A complete description of processes to update, change or remove alarms in order to meet changing requirements or optimize systems. Operation The site is run with the new alarm systems. Operator- supporting tools are installed; further trainings are given. INTECH trains operators how to handle alarms and provides alarm management tools. Maintenance Alarms are periodically calibrated and tested for accuracy, repairs and replacement activities are performed. INTECH follows standard maintenance procedures and performs fidelity tests. Monitoring & Assessment Data is monitored and benchmarked against performance standards defined in the alarm philosophy. Part of the continuous improvement effort, with periodic alarm and system audits

4 Performance and Financial Benefits INTECH s Alarm Management Solutions ensure that incidents occurring from bad alarm configuration are minimized. INTECH achieves this by classifying, prioritizing and optimizing alarms to generate useful information for operators. This ensures that operators are immediately alerted to issues that can potentially cause serious damage to the plant and environment, and offset a large portion of the plant s past profitability. Plant Profitability Maximum Profitability Region Normal Operating Region Profitable Region Break Even Point Net Loss Due to Minor Process Upset Optimum Profitability APC & Optimization Substantial Net Loss Due to Unscheduled Plant Shutdown Time Reduction in Overall Alarms: Most modern alarm systems are implemented at the software level and require no physical hardware installation, this has led to a significant increase in the number of available alarms at any site - a growth fueled by international standards that require periodic monitoring for process assessment. The major drawback to all this however is an overwhelming amount of alarm notifications being constantly generated during operation in the absence of alarm management. Before Rationalization After Rationalization Daily Alarm Count: > 16,000 Daily Alarm Count: < 5,000 Hourly Average for Week: 742 Hourly Average for Week: 390 High Priority Alarms Contribution: 65% High Priority Alarms Contribution: 43% # of Daily Alarms Alarms Optimization Implemented All Alarms Enabled Alarms INTECH s Alarm Management reduces overall alarms going off to manageable numbers through continuous improvement. INTECH identifies bad actor alarms - alarms that cause nearly half of all alarms - and optimizes them. Additionally nuisance alarms - which don t serve any real purpose - are identified and reconfigured to reduce overall alarms. This results in up to 90% reduction in average daily alarms. INTECH s Alarm Management Suite Alarms Analytics Dashboards Module INTECH delivers software and services for operations and process optimization with a variety of deterministic optimization techniques that may be manually or automatically selected based on the objective function and constraints. Alarms Analytics Dashboards module delivers KPIs, metrics and reports based on ISA 18.2 standards and EEMUA 191 guidelines. Alarms Rationalization Module This module provides comprehensive data management for identifying & documenting causes, consequences, and corrective actions as well as alarm set points, alarm enabled states, priorities, purpose, operator action, consequence of not attending alarm, min. time to respond to the alarm, dead band, requirement of alarms suppression and requirement of de-bounce timer Static, State-Based and Dynamic Alarms Suppression Module INTECH, with it's rich experience in operations and process, identifies process and equipment states. Based on ON, OFF, INITATING, START UP, SHUT DOWN etc. states, alarms can be dynamically enabled or disabled.
