In Iraq, an extensive network of pipelines is of vital importance for the transportation of hydrocarbon products, drinking water, and crude oil through the pipelines. The underground infrastructures experience corrosion processes, which therefore requires keeping up with the application of protective measures. This is a simulation survey that takes into account the cathodic protection optimization to reduce such hazards. Employing the Wenner four-terminal method enabled assessment of elements that affect cathodic protection such as environmental factors and soil resistivity across selected sites for the surveys. Soil pH ranges within the range of 7-8, together with anode voltage and current readings were the basis of the simulation models. These models played a crucial role in predicting the best anode locations, operating voltages and currents for various conditions and by comparing the results with empirical data from field experiments it is easy to evaluate the results. The analysis of rectifier voltage, the number of anodes, the anode resistance, and the pipeline current led to the production of the most cost-efficient designs for pipeline protection. Thus, as a result, a segment at station number 2 requires 2.5A current for its protection over the same length and a segment at station number 4 needs 12A current for its protection. Through the integration of simulation outcomes with the field observation the study highlights the accuracy and efficiency of the modeled cathodic protection systems that substantiate their fundamental role in the sustainable management of the pipeline. The results reached in this study add a great deal to this body of knowledge on the subject of subterranean structure preservation, showing this paradigm for the design and optimization of cathodic protection systems against corrosion and erosion which ensures the durability and reliability of pipeline networks.
