Transmission pipelines are monitored 24/7 from control rooms using software that gathers critical information from the pipeline. Pipeline operators use a wide range of tools to monitor pipelines constantly – sensors that monitor temperature, flow rate and pressure, fiber optics, video cameras, in-line inspection tools, aerial surveillance and even people walking the pipeline right-of-way. These tools and systems quickly alert technicians if a change is detected in the pipeline. Then using valves located at key points in the line, pipeline operators can quickly shut off the flow of product in the pipeline at a moment’s notice. These valves are controlled remotely from the pipeline operator’s control centre.
