LINING A GEOMETRICALLY COMPLEX MESS INVOLVING A LEAKING GAS MAIN

The award winning renewal of a 30 to 36 in diameter leaking high pressure (HP) gas main crosses a river in central New Jersey. It was affectionately named “The Mess” due to multiple complexities that required engineering and design solutions for a successful lining operation.

In 30 years, I haven’t met a utility that didn’t have pipelines along bridges in their inventory. As bridges age, so do the pipelines. We are all getting older. Over forty percent of the bridges in the US are over fifty years old. In the Northeast, gas pipelines and bridges are typically 75 - 100 years old.
