1. TransCanada Corporation (TSX/NYSE: TRP)
TransCanada is a leading North American energy infrastructure company with over 60 years of experience in energy transportation.
Approximately $48 billion of premium pipeline and energy assets.
The organization employs over 4,900 people in nearly 50 professions, trades and fields, located in 7 provinces and 32 states.
Network of approximately 68,500 km of wholly owned and 11,500 km of partially owned natural gas pipelines 1

2. TransCanada Pipeline Safety Overview
Pipelines are the safest method of transporting the huge volumes of natural gas that must be moved throughout Canada every day
Safety of the public, employees and the environment is the top priority of TransCanada’s pipeline integrity programs  
In the over 60 years TransCanada has operated pipelines there have been no injuries to members of the public as a result of the operation of our assets
 Safety and reliability is the key to ensuring TransCanada and the pipeline industry are able to continue operating and building energy infrastructure in North America for years to come
Our goal is for zero pipeline incidents

3. Multifaceted Pipeline Safety
Design
Environmental Considerations
Construction
Operations
Maintenance

4. Design Materials Crossing design technologies
Thicker walled pipe (ie. Crossings)
High strength steel: X80 (Grade 550) and X100 (Grade 690)
Crossing design technologies
New trenchless crossing techniques (ie. Direct Pipe)

5. Design Geohazard Assessments Examples:
Unstable slopes, such as landslides
Seismic hazards
Lateral and vertical migration of watercourses at crossings
Permafrost expansive or collapsible soils
Risk Control Techniques:
Avoidance (routing)
Stabilization (re-alignment, heavy wall, wider ditch to allow for engineered backfill to allow pipe to move)
Monitoring (slope indicators, strain gauges, visual inspection)

6. Environmental Considerations
Traditional Land Use
Route (Minimize Disturbance)
Watercourses and Wetlands
Vegetation
Wildlife and Wildlife Habitat
Species at Risk
Air Quality and Noise
Archaeology / Paleontological
Opportunity: Engagement
Utilize Local Knowledge - Collaboration

7. Construction Advancements in Welding Techniques
Dual Torch Mechanized Welding

8. Construction Advancements in Coating Technologies
Inside Diameter Coating
Automated Coating Machines

9. Automated Ultrasonic Testing (AUT)
Construction
TransCanada Inspection through construction process
Material manufacturing (pipe, valves, etc.)
Shop fabrication
Pipeline installation
Non-Destructive Examination
Examination of the entire circumference of each joint by radiographic or ultrasonic methods
Goal: To ensure the integrity of each joint
Automated Ultrasonic Testing (AUT)

10. Operations & Maintenance Activities
Aerial Patrol: Regular inspection of pipeline route using low-flying helicopters and planes
Cover Surveys: Investigations in areas where we suspect wind or water erosion may have reduced depth of cover
Geotechnical Monitoring: Visual inspection, installed slope indicators and strain gauges
Hydrostatic Testing: Completed during the installation of all new pipelines, and when further investigation of an existing line is required

11. Operations & Maintenance
In-line Inspection (‘pigging’): Specialized internal inspection devices called ‘smart pigs’ travel through the pipeline collecting data. The data is analyzed to determine if there are areas of concern which require further investigation
New In-line inspection tool (Electro Magnetic Acoustic Transducer)

12. Operations & Maintenance
Cathodic Protection: a low-voltage electric current is induced in the vicinity of the pipeline to inhibit pipeline corrosion
Investigative Digs: Sections of pipeline are excavated to examine the condition and to ensure integrity
24 Hour Gas Control Center: Staff can detect changes in pressure along pipeline and can ensure pipelines are operating correctly
In 2012 TransCanada invested $900 MM in PL integrity and proactive maintenance programs
