"TransCanada Corp., which says Keystone XL will be the safest pipeline ever built, isn’t planning to use infrared sensors or fiber-optic cables to detect spills along the system’s 2,000-mile (3,200-kilometer) path to Texas refineries from fields in Alberta."
"Pipeline companies have been slow to adopt new leak detection technology, including infrared equipment on helicopters flying 80 miles an hour or acoustic sensors that can identify the sound of oil seeping from a pinhole-sized opening. Instead of tools that can find even the smallest leaks, TransCanada will search for spills using software-based methods and traditional flyovers and surveys.
As pipelines multiply across North America to carry booming supplies of oil and natural gas, a series of recent spills and explosions are raising concerns about the safety of the conduits, including Keystone XL, which is awaiting U.S. government approval."
