Corrosion is the biggest enemy of transmission pipelines. According to PHSMA, about 40% of pipeline damage and leakage is the direct result of corrosion, and other types of pipeline damage, such as excavation and natural force damage, are also highly associated with pipeline corrosion and can be easily triggered. Overall, soil corrosivity is the key and influences the degree of corrosion that happens on a pipeline.
​
In this section, the objective is to determine the soil corrosivity and assess the corrosion risks of pipelines by developing a continuous soil corrosivity index surface by using ArcMap and ArcGIS Pro in Harris County. Given the fact that soil corrosivity is influenced by a number of different soil properties at different levels, multi-criteria evaluation (MCE) was used as the technique to determine soil corrosivity in Harris County.

The lack of preparedness of local governments and energy companies led to this serious state-wide power outage and energy crisis. Therefore, to prevent similar series of disasters from happening, it is crucial to ensure and assess the resiliency and integrity of current transmission pipelines in the State of Texas.
In this project, the main objective is to investigate the driving factors of pipeline incidents (failures, accidents) of currently existing pipelines.
