Tim Ross, PureHM, Canada, describes the downfalls of sticking to conventional pig tracking. Despite the potential for leaks or ruptures, pipelines are still the safest way to transport natural gas and liquid hydrocarbon fuel products - much more so than using tanker ships, trains and trucks, which have a much higher failure rate than pipelines. However, both existing and new pipelines that transport these critical energy resources are coming under increased scrutiny as the transported materials can be harmful to the environment if released. This threat is particularly high in areas where the spill could contaminate a water source and become difficult to contain and clean up.
