2. Bellingham Washington On June 10, 1999 an Olympic Pipe Line Company pipeline ruptured and spilled over 236,000 gallons of gasoline into Hanna and Whatcom Creeks. The resulting explosion consisted of a fireball which raced one and one-half miles down Whatcom Creek and created a smoke plume twenty to thirty thousand feet high. Three people were killed - two ten-year old boys and an 18-year old young man who was fishing in Whatcom Creek. Eight people were injured and extensive damage incurred over the mile and one-half length of Whatcom Creek.

3. Carlsbad New Mexico On August 19, 2000. A transmission pipeline ruptured and a fire killed 12 campers near Carlsbad, New Mexico. Federal investigators determined that the cause was severe internal corrosion of transmission pipeline; over 70% of the wall had been eaten away near the rupture site . Just Pig-it

13. Magnetic flux leakage (MFL) is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic principle is that a powerful magnet is used to magnetize the steel. At areas where there is corrosion or missing metal, the magnetic field "leaks" from the steel. In an MFL tool, a magnetic detector is placed between the poles of the magnet to detect the leakage field. Analysts interpret the chart recording of the leakage field to identify damaged areas and hopefully to estimate the depth of metal loss. PIPELINE INTEGRITY MFL PIGS

14. MFL can detect corrosion by sensing magnetic leakage. First, it initiates a magnetic field in the pipeline. If there are any flaws in the pipeline wall, some of the magnetic field will escape. Sensors onboard the pigs detect and measure that leakage. Smart pigs equipped with MFL technology can determine whether the corrosion is internal or external, and they can also measure for changes in the thickness of the walls. PIPELINE INTEGRITY MFL PIGS
