About

Sung-Ja Koo is a leading researcher in the field of robotic pipeline inspection, with a primary focus on developing advanced solutions for the natural gas industry. His key research areas include in-pipe robotics, magnetic flux leakage (MFL) sensing systems, and non-destructive evaluation for unpiggable pipelines. Dr. Koo’s major contributions center on the design and implementation of the "PIBOT" system—a specialized in-line inspection robot capable of navigating and inspecting unpiggable natural gas pipelines. His 2013 paper, "Development of MFL system for in-pipe robot for unpiggable natural gas pipelines," which has garnered 11 citations, details the integration of MFL technology into this robotic platform, enabling high-sensitivity defect detection in challenging pipeline geometries. Building on this work, his 2016 study, "Inspection of Unpiggable Natural Gas Pipelines Using In-Pipe Robot," with 9 citations, demonstrates the practical deployment and validation of the PIBOT system in real-world conditions. These achievements, supported by collaboration with KOGAS (Korea Gas Corporation), have significantly advanced the safety and efficiency of natural gas infrastructure maintenance, offering a robust alternative to traditional inspection methods for hard-to-reach pipelines.
