A Graduate Creative Project Submitted to the Graduate Faculty of The Texas A&M University – Corpus Christi in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE in GEOSPATIAL SURVEYING ENGINEERING in CORPUS CHRISTI, TEXAS.
Two GIS-based analysis tools were developed for gas transmission pipelines in this project. One tool determines class location designations along a gas transmission pipeline to satisfy the U.S. Department of Transportation (DOT) regulations. The second tool calculates the maximum allowable operating pressure (MAOP) based on the structural properties of pipeline segments. The DOT regulations in 49 CFR 192 explain the class location definitions and the operating pressure as a function of class location design factors. The DOT class locations indicate a level of the potential risk of damage to a pipeline from external activities and the potential risk to people and property near the pipeline. Class location categories set the parameters that affect the MAOP values for operating a gas pipeline. The categories are a function of population and infrastructure in proximity to the pipeline. Specifying the MAOP value reduces the risks to the pipeline and surrounding area.
