To solve the key technical problems which threaten the safety of natural gas pipeline, much research was carried out. First, the finite models of pipes with different lengths were calculated and the pipeline offset tolerance criterion was established. Second, 43.335 km optical fiber was installed along the pipeline as well as the leakage inspecting box was developed. Third, the gas diffusion instant calculation method was built, as well as the fire and explosion hazard forecasting software was developed. Based on the GIS platform, the achievements in above scopes as well as the SCADA system, the GPS location service of vehicles for maintenance, the IP telephone and video service, the regional broadcasting service, and the short message service, was integrated to form the emergency rescue decision assistant system. Applications show that the system has a good ability of emergency response, command and control, and has well applied in practice.
