Design
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.
Construction
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.
Operations
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.
