Agenda

Alarm Problems in the Pipeline Industry Control Room Management Plan Alarm Handling vs. Alarm Management What is Alarm Management? The Regulatory Drivers

Pipes Act 2006, PHMSA–NOPR, API 1167 International Alarm Management Standards

Alarm Management Approaches Key Performance Indicators Summary and Conclusion


Factors Contributing to Alarm Overload

The following factors represent some of the more common systemic issues that contribute to the alarm problem that the pipeline industry faces.

Running pipelines/units harder increases the need for alarms

Reduced profits resulting in lower levels of maintenance

Increased and more stringent safety requirements due to incidents in the industry

Increased reliance on monitoring technology; including security monitoring

Communication alarms inherent to SCADA increase alarm activity

Too many people allowed to determine/configure alarms and settings


What is Alarm Management?

Alarm Philosophy Benchmark and performance audit Rationalization (rules of engagement)

“Bad actor” / repeat offender cleanup Dynamic and state-based alarming Implementation Continuous Improvement Management of Change

Alarm Handling vs. Alarm Management

Alarm Handling

• Real Time• Basic Alarming

• Trip Points• Rate of Change• Deviation

• Notification• Enhanced Alarming

• Dynamic• State-based• Logic-based• Alarm Suppression • Predictive/Smart Alarms

Alarm Management

• Offline or Online• Alarm, Event, Op-change

Archival• Analysis, KPIs• Rationalization• Change Management• Knowledge Capture• Operator Notes• Notification / Escalation• Dynamic Configuration

Change• Enhanced Alarm Setup

PHMSA Proposed Rule – Alarm Management

Pipeline & Hazardous Materials Safety Administration requires that a Control Room Management (CRM) Plan must address many items, including:

Detailed provisions relating to alarm management ensuring controllers will respond appropriately to alarms and notifications

SCADA operations must be reviewed regularly

SCADA configuration and alarm management operations must be reviewed at least once each calendar year

include identification of abnormal or emergency operating conditions and a review of controller response actions.

API RP 1167

An API workgroup is currently developing an Alarm Management Recommended Practice (API RP 1167).

The expected outcome is a consensus document that could address definitions, effective alarm system design, good alarm audit and review practices and strategies to minimize overload and nuisance alarms.

Implementation of the recommendations in these documents should satisfy the Pipes Act of 2006 requirements.

AGA Alarm Management Whitepaper Reviewing API 1167 to determine if they will publish their

paper, which is likely to follow the API document.


Other International Alarm Standards

EEMUA 191 (Engineering Equipment & Materials Users Association)

Guide to the design, management and procurement of alarm systems - EEMUA Publication 191

First published in 1999 and revised in 2007 and has become recognized and followed the world over as a

reference publication in this area.

ISA SP-18 Standards & Practices 18 18.02 is a standard, not a guideline or recommended practice developed in accordance with ANSI methodologies it is likely to be regarded as "recognized and generally

accepted good engineering practice (RAGAGEP)" by regulatory agencies


Alarm Management Approaches

D-I-Y (Do It Yourself) Spreadsheet approach, custom reports/applications Good early results, but can be difficult to sustain

3rd Party Alarm Management with extra services required Some Alarm Management providers sell licenses

that require additional effort to deliver required functionality

3rd Party Alarm Management on “turnkey” basis Proven quick deployment, analysis starts on day

one Additional services available if desired


Common Alarm Management Tools

What should be in an Alarm Management solution?

Rich Alarm Management Tools “Out of the Box” Alarm Reduction Analysis

Frequency, Duration, Chattering, Related, Flood, Alarm State, Nuisance, …

Alarm performance measurement and reporting Efficient alarm system engineering Complete Alarm life cycle management


Managed Alarms – Targets / KPIs

KPI (Key Performance Indicator) EEMUA Recommendations

Manageable Steady State 1 per 10 minutes

Flood State 10 in 10 minutes

Average Process Alarm Rate 5 per hour or 120 per day

% of Time Alarms Exceed Target Ave. Rate 0%

Peak Alarm Hourly Rate 15 per hour

Peak Alarm Minute Rate 2 per minute

Alarm Activity Priority Distribution 5%High,15% Medium, 80% Low

Alarms Within 10 Minutes of a Major Upset 10 or less

Chattering Alarms 0

Stale alarms (more than 1 day old) 0

Unauthorized Changes to Alarm Settings 0


Conclusion and SummaryBenefits of Alarm Management

Improved operation, quieter control rooms Visibility and Accountability Fewer, but more relevant alarms Better basic control Better documentation / advisory information

Better alarm flood control and avoidance Labor savings

Controller load balancing one pipeline shutdown / incident could cancel any gains

from a year of process improvements

Increased Pipeline uptime Avoidance of unplanned outages

Regulatory compliance
