West Ohio Gas, which is owned by Dominion East Ohio Gas Company, is located in Lima, Ohio and operates the natural gas distribution system. The gas system is comprised of high-pressure, medium-pressure and low-pressure gas lines. The distribution system has been in operation since 1886 in West Ohio. Most of these pipes were installed with a larger diameter distribution lines feeding smaller distribution lines branching off to every street within the City of Lima. Dominion East Ohio operates and maintains approximately 1300 miles of pipeline in West Ohio. Some of these lines are still active from the 1800’s. This paper examines the risks associated with the pipelines within the Lima, Ohio distribution system. The research investigated the following data for every pipeline in the system: year of installation, leak history, cause of failure, and coating type to assess the risk of failure of the distribution systems. Data from various pipelines were analyzed to look for a trend in failure rates, causes of failures, and aging characteristics. The results should enable the decision makers to prioritize the gas pipelines replacement.
