  •  A bunch of oil (4+ / 0-)

    Pipelines are breaking lately is Global Warming to blame is my question
    Next question  or did the steel for all these pipelines come from the same pipe maker a pipemaker who cut corners?
       Were these pipelines all built around the same time by the same contractor? Has this contractor had problems about the work he did reported before?

    •  Don't know about this one, but the AR pipeline (8+ / 0-)

      is 65-70 years old. As are a great many of these pipelines. That in itself is a HUGE problem - At that age, things tend to break down.

    •  Nope (5+ / 0-)

      a loosening of regulatory requirements (legislation and enforcement) we have had the lag period and now things are beginning to fall apart. And while industry is yucking it up with those who are supposed to oversee them  or worse, self regulating, It will get a whole lot worse before it gets better.

    •  Way too many lines (1+ / 0-)
      Recommended by:

      of many different ages to be one contractor. Major Pipeline map of US  If you include all of the smaller ones, there are areas of KS, TX and some other states completely covered. Global warming factors into the project because the tar sands will add so much more to it than the fossil fuels we have been using. 3 x the carbon per energy unit produced.

      Age of the lines is one factor. The burial makes it harder to check for problems. Above surface makes them much easier for idiots and cults to mess with.

      The Exxon line had been shut down, changes made to reverse the flow, and the material changed from light crude to diluted tar sands - a far more corrosive material. Adding to the aging part of failure.

      So one complication with this issue is that some existing pipelines are already carrying tar sands. KS XL is supposed to be able to do this much safer because it has been designed for more corrosive material. What is much more important to the developers' is the higher capacity of barrels per day (BPD) that the line can deliver. XL would be 10 times the capacity of Exxon's and similar ones.

      Exactly how well the line will hold up to the corrosive oil, given the speed and volume, is likely full of assumptions made with inadequate testing. Basic physics:  Force = mass x speed. Add corrosive sand and chemicals. Tests?

      The Canadian government has too many people determined to bring the tax money in regardless of how much it costs the country in health, pollution and devastation of their Boreal Forest, which is also critical to the global ecosystem. The companies trying to get the XL built have said that not building it would cut the financing options - until they find others.

      If we refuse to allow the pipeline to be built, the other lines will continue to carry tar sands oil and the older lines are very likely to keep breaking down. It is a start at slowing the speed which the Alberta strip mining is planned to increase. I didn't write down the figures I first heard, they were along the lines that there are ~14 mining pits operating and twenty something planned with financing waiting. If it is stopped long enough for alternative energy sources to gain ground at the rate they currently are, and faster, it could   divert the money to investing in sustainable sources.

      Want to know more about the operations and what they are already doing to the environment, animals and humans? Get acquainted with Al Jazeera if you aren't already. The official American branch is going up soon.

    •  My understanding is that this "oil" (0+ / 0-)

      is basically loaded with abrasive particles (thus the "sands"). Even thinned with toxic benzene, when you pipe this stuff under pressure through old lines constructed to handle cleaner oil, any thin spots are going to fail pretty quickly.

      Another poster noted that the direction in which the oil is piped has been reversed in a number of places to take advantage of different routes to get the stuff out of Canada, since "tar sands" oil can only be processed by some refineries.

      But "no worries" - after all a drop of benzene only makes 75,000 gallons of water unfit for use by humans, animals, and plants . . .
