In this paper, we develop real-time monitoring system to detect third-party damage on natural gas<br/> pipeline by using sound propagation model. Since many third-party incidents cause damage that does<br/> not lead to immediate rupture but can grow with time, the developed real-time monitoring system can<br/> execute a significant role in reducing many third-party damage incidents. The developed system is<br/> composed of three steps as follows: i) DSP based system, ii) wireless communication system, iii) the<br/> calculation and monitoring software to detect the position of third-party damage using the propagation<br/> speed of acoustic wave. Furthermore, the developed system was set at practical offshore pipeline<br/> between two islands in Korea and it has been operating in real time.
