[QUOTE="fly2cast, post: 122821, member: 656"] I agree. We need the pipelines but these issues of detecting leaks on the pipelines really need to be addressed by oil companies. They have nobody to blame but themselves for the negative views people have of the pipelines. I talked to a guy that works in the pipeline business. I asked him how they detect leaks on the pipelines. He said its as simple as measuring the amount of product going in compared to what comes out. That really concerns me. At gas stations, the piping run from the underground tanks to the pumps may be 100 feet long in a 2 inch diameter pipe. They are required to have two forms of leak detection on the pressurized piping and have them double walled and totally contained. And these systems fail sometimes. There is no way to detect leaks by inventory alone. I don't know exactly whats required of pipelines. I do know that with large diameter pipes that run for miles it would be darn near impossible to detect leaks. So I'm curious what they do. One pretty easy way to detect leaks would be to have double-walled systems with leak monitoring of the interstitial space. But as far as I know, they don't use double-walled systems. Anybody know what they use? [/QUOTE]
