Thank you, Mr. Chairman.
We see two major realities confronting us in the world today. A fourfold increase in global population over the past century, from about 1.7 to 7 billion people, together with rising prosperity and the demand for heating, cooling, lighting, transportation, food, clothing, and industrial goods, has led to an overall tenfold increase in the demand for energy over that same period.
Today, the world relies heavily on energy. To move energy cost effectively, the emergence of oil and gas triggered a significant expansion of pipelines across North America, connecting sources of production to places of use. Canada has the opportunity to build upon new and innovative technologies to increase pipeline safety and reliability and improve our economic performance at the same time.
Pipelines handle a range of products, not only oil and gas but particularly water, sewage, LPGs, chemicals, and slurries as well. They range in age from brand new to over a century old. Existing pipelines are made of wood, cast iron, concrete, steel, and plastics, and they all have a range of performance and design criteria.
For this discussion, I believe that your major interest is in the oil and gas pipeline, so I'm going to focus on that aspect.
Today in Canada there is approximately 840,000 kilometres of oil and gas pipelines, from gathering to feeder, transmission, and distribution lines. Natural gas pipelines make up over 75,000 kilometres and oil transmission pipelines almost 40,000 kilometres. This network has allowed Canada to evolve from a net oil and gas importer to a major net exporter, with associated economic benefits. So the need for pipelines is likely to continue.
The International Energy Agency projects global energy demand will grow by more than a third by 2035, and even under its most optimistic scenario projects that fossil fuels will dominate energy supply, meeting more than 60% of global energy demand. Of course, we know the Canadian oil sands are one of the largest energy sources and will undoubtedly be filling part of that demand.
Energy of all kinds is going to need to be moved from where it is produced to where it's needed. Canada certainly has resources to supply the world in a way that is acceptable, by investing in technological innovations that would increase public confidence in design, manufacturing, operation, and monitoring of pipelines. To do so, we need to maximize safety and economic benefits while minimizing and mitigating the potential impacts on the environment and human health.
The first challenge we face is an aging pipeline system. R and D opportunities associated with this part of the system include developing methods to determine existing levels of stress and strain in operating pipelines; ensuring that the strength of the girth welds remains greater than that of the pipe materials; and understanding the effects of bending, misalignment, material anisotropy, and so on.
We know that while a pipeline, relative to the volume handled, is one of the safest and most economical modes of transporting oil and gas, there are still failures. Pipeline leaks and ruptures can result in significant negative consequences and, as we've seen, make new pipeline proposals quite contentious. As has already been mentioned, cracking and corrosion account for 60% of all pipeline ruptures.
The growth of population means that many older buried pipelines are now passing through populated areas, with increased risks to human health and the need for improved mitigation in the event of failures. There's a need for continuous inspection and monitoring so that potential failures can be detected before they occur. It's important to figure out how to do this in a cost-effective manner and to develop the means to minimize the damages from any failures that do occur.
The second challenge is to develop technologies that will improve pipelines, particularly new ones, such as enhancing the fracture resistance of pipe materials, new joining techniques for mixed material pipelines, reducing the environmental impacts as a result of the footprint and noise during construction, and so on.
There's also the need for technologies that can significantly improve pipeline operations and monitoring, such as detecting internal and external corrosion and defects, continuous in-line inspection, and ultrasonic testing.
Some options for this include robotics, locating defects using on-line intelligent inspection pigs that you can run through the pipe with ultrasonic tools, and even electrorheology, where you would apply perhaps electric currents to significantly reduce crude oil viscosity. There are many ways of changing the performance.
In order to make a step change in our pipeline system, we need to build consensus among governments, industry and citizens on the investment we need to make to achieve an acceptable level of safety and reliability, return on investment and contribution to economic growth and quality of life.
This brings us to our third and possibly biggest challenge, and that is the level of risk we are prepared to accept. How will we determine the level of risk we are prepared to tolerate as a condition for investing in new pipelines? What level of performance should pipelines deliver relative to other transportation modes and infrastructure, for example airplanes, railways, cars, trucks and ships? How much investment should be made and by whom to develop the technology that can achieve this level of performance?
Organizations such as NRC play a critical role in de-risking technology for governments and industry with the end goal of creating social and economic benefits for Canada. For example, NRC delivers expertise and benefits in many scientific and engineering disciplines that can be applied to pipeline safety and innovation, including: structural and material health monitoring; event sensors for solids, liquids and gases, including sensors on unmanned vehicles, for example; advanced material substitution and fabrication; wear and corrosion mitigation; bio-monitoring and bio-remediation of hydrocarbon contamination, just to name a few.
Our new NRC model is specifically designed to focus on critical challenges important to government and industry, and this may form the basis for a strong program that we might participate in delivering.
In conclusion, Canada certainly has expertise to bring to bear to overcome the technological challenges associated with increasing the safety and reliability of pipelines, and also has the opportunity to address these challenges, so that Canadians can continue to benefit from resource development such advancements would enable.
Thank you.
