Our safety program starts before construction.
To ensure the integrity of our pipelines before they go in the ground, TransCanada uses:
During construction, we require every weld to be inspected by qualified independent inspectors and we use radiography and automated ultrasonic testing techniques to check for irregularities before our pipelines go into service. Qualified inspection personnel visually inspect every phase of the construction process to ensure compliance with company and regulatory standards and specifications.
TransCanada takes significant steps to prevent and minimize the chances of a pipeline leak and detect irregularities both before beginning transportation service and during operations.
We use state-of-the-art leak-detection systems, safety features such as shut-off valves and highly specialized training for people working on our assets from the construction process to operations.
During operations, the pipelines are monitored 24 hours per day, seven days per week by a state-of-the-art oil or gas control centre. In addition, TransCanada has a number of programs that help monitor the integrity of the pipeline including aerial patrols, geotechnical monitoring, in-line inspection, investigative digs and more.
