  1. My Pipeline Worries Mike Holmstrom San Jose, CA The 600 pound monsters still in the room for pipeline safety

  2. My background with pipelines: San Bernardino 1989: Train derailment on top of a pipeline, cleanup of spilled load and train wreckage, but no hydrostatic test!

  3. The first worry: LF-ERW seams Flash seam welds also weak ILI has missed areas that failed just a few years later. Get more picky with anomalies on this type of pipe? Is spike hydrotesting enough? Spike test pipelines with LF-ERW pipe that have not had previous seam failures? Still seen failing: Jackson WI in August 2012, Jones & Laughlin LF-ERW made in 1961

  4. Reinventing the same problem? LF-ERW pipe not made in 40 years. But, lack of fusion was seen in modern pipe by x-rays.

  5. Second: Locate failures Locate Tech training Abandoned in place pipelines misleading? Plastic pipe locating woes Resolution of buried objects that seem to be pipes NEVER go by just maps, drawings, or GPS to dig by!!

  6. Third: Depth of coverage Soil loss, drought, etc., add up over decades Some think you don't have to call 811 if you don't dig deep enough, yet, utilities may become very shallow!

  7. My Efforts on the Web Working hard on the Wikipedia “List of pipeline accidents in the United States” http://en.wikipedia.org/wiki/Pipeline_accidents
