Each year, we dedicate a significant portion of our operating budget to our comprehensive pipeline and facility integrity management activities.
Pembina’s pipeline and facility integrity management programs include several systems and processes designed to ensure proactive and transparent management of our pipelines and facilities.
These programs fall under the umbrella of our integrity management program and incorporate industry best practices designed to meet or exceed regulatory requirements. Our goal is to achieve enhanced safety, reliability and longevity through the entire lifecycle of our pipelines and facilities.
Integrity management begins at the engineering and design phase.
At the early stages of building a new pipeline, we select pipeline routes which avoid geologically unstable or high consequence areas. To further reduce risk, we design our pipelines so they can be safely shut down and so that segments of the pipeline can be isolated at intervals along the system. Where appropriate, we take extra safety precautions such as increasing pipe wall thickness or depth-of-cover.
When it comes to choosing materials for new construction, Pembina only uses products that have been manufactured to meet the highest quality standards and specifications.
Our qualified and experienced inspectors oversee all phases of pipeline construction. Each weld is assessed to ensure that it’s sound. Prior to installation, we coat the entire external surface of our pipelines with materials designed to safeguard against environmental damage and corrosion. In addition, as part of pipeline operations, a very low-voltage electrical current, called cathodic protection, is applied to the pipeline which further protects the pipe from corrosion. Once construction is complete, we put in place above-ground warning signs to clearly mark our pipeline right-of-way.
Our operations team ensures our pipelines operate safely and efficiently. Pembina staff at our control centre in Sherwood Park, Alberta, monitor our pipelines 24 hours a day, 365 days per year.
Through our Asset Integrity Management Program, we use inspection technologies to detect corrosion and cracks in our pipe.
We protect our pipelines against possible damage by third-party excavators or construction activity by working with municipal planners, contractors and landowners along our pipeline routes. We also conduct routine right–of–way aerial patrols and are a long-standing member of the Alberta and British Columbia One Call systems.
Abandonment is the final phase of a pipeline's lifecycle.
When we decide to permanently cease operations of any of our pipeline systems, we follow all applicable laws and regulations. Through the abandonment process, we work with regulatory bodies to ensure that we do what's best for the environment and the people living around the pipeline. This includes either cleaning the pipeline of all product and leaving it in place or removing the pipeline and filling in the ground.
Our Facility Integrity Program, part of our Asset Integrity Management Program, ensures operational safety and regulatory compliance for all equipment that operates under pressure.
We execute scheduled maintenance at our facilities with the goal of meeting or exceeding requirements for pressure equipment, tank and piping inspections. Scheduled maintenance is important to Pembina, as it allows us to ensure safe, reliable and continuous operation of our facilities.
