Slide 3: Pipeline Integrity Management Program

  • An example of a proactive program governed by our Operational Management System
  • Full life cycle management of pipeline integrity and safety
  • Illustration of pyramid: OMS, Integrity Management Program, System Wide Rish Assessment, Threat Management, Preventative Integrity Maintenance
  • Illustration of Asset Management System cycle:
    • Plan: Commitment Statement, Strategy and Objectives, Structure and Responsibilities, Communication Management
    • Plan: Asset Management Planning, Information Management, Risk Management, Compliance Management
    • Do: Resource Management, Management of Change, Implement AMP's, Incidient and Emergency Investigation
    • Check: Performance and Conditioning Monitoring, Control of Non-Conformances, Internal System Audit
    • Act: Continual Improvement, Management Review

Slide 4: System Wide Risk Assessment (SWRA)

  • Time Dependent Threat
    • External Corrosion
    • Internal Corrosion
    • Stress Corrosion Cracking
  • Stable Threat
    • Manufacturing Defects
    • Construction Defects
    • Equipment Failures
  • Time Independent Threats
    • 3rd Party Damage
    • Weather and Outside Forces
    • Incorrect Operations
      • % Mitigation Measures Implemented
      • Participation in Industry Foundations, Committees, and Organizations
      • Completion of Root Cause Analysis

Slide 6: In-Line Inspection (ILI)

ILI uses pipeline inspection gauges (PIG) for condition monitoring and maintenance

Enables identification, analysis, susceptibility assessment, risk management, and remediation

# Features Identified, Accuracy of ILI Calls, # of ILIs and Distance Run

  • 2015 Statistics
    • 172 In-line inspections performed in 2015
    • 15,334 km of ILI run in 2015
    • 5 Main Types of ILI (MFL, EMAT, Caliper, Smartball, Cleaning)

Slide 7: Damage Prevention

  • Damage prevention - the proactive strategy to minimizing the probability of an incident caused by third parties (government, public, contractors, land owners, etc.).
    • Pulic Awareness
    • Mechanical Damage
    • Crossings
      • # One Call Notifications per Unauthorized Activity / 1000km
      • Timely Completion of Crossing Requests
      • Contractor Education Engagements
      • Landowner, Government, Contractor and Public Engagements
      • Reduction in Unauthorized Activities
      • Aerial Patrol Coverage
  • 2015 Statistics
    • 3003 Aerial patrol and 485,065 km flown
    • 118,318 One call requests processed
    • 818,755 Baseline mailings (public outreach)
    • 2295 Crossing agreements processed
    • 163 Unauthorized activities with 63 investigated
