A Bibliometrics Analysis of Research Trends on Pipeline Cathodic Protection(CP)

Pipeline infrastructure has been expanded hundreds of kilometers and runs through remote, harsh, and corrosive areas. Due to a harsh environment abd aging factor the pipeline's corrosion leakage prone to happen, and cathodic protection (CP) techniques are required to prevent corrosion. In prevent the corrosion, the voltage between the protection metal and the auxiliary anode or pipe to soil potential (PSP) must be controlled on the desired level. The voltage can be controlled using any controlling method such as manual control, automatic control, or intelligence control using the IoT approach. Since CP is the most practical method used among researchers in preventing corrosion in the pipeline, a statistical review has been conducted to investigate the trends of the research study. All the data on CP of pipeline structure was gathered from the Scopus database. Harzing's Publish or Perish software is used to integrate the acquired data, while the VOS viewer is utilized to visualize the data. Additionally, Microsoft Excel was used to analyze the data. As of 18th September 2021, 571 documents were retrieved and analyzed. Most of the research in the CP was in material science, followed by engineering field. Cathodic protections and pipeline is the most keyword use and represent the main area of research covered in CP. United States was the most active country publishing the research activity on the CP, followed by researchers from China. This analysis is used to determine the popularity, impacts of publications and impact of research area on cathodic protection study.
