Application and technology of earthquake monitoring and early-warning for long-distance oil and gas pipeline
Zhan Meiping · World Earthquake Engineering · 2010
In the recent four decades of oil and gas pipeline industry,strong earthquakes have caused numerous pipeline failures.The aim of earthquake monitoring and early-warning for long-distance oil and gas pipelines is not for forecasting earthquake,but for rapid reporting post-earthquake information,which provide emergency decisions and rescue plans for pipeline engineering after earthquakes.Some typical applications of earthquake monitoring and early-warning system on the pipelines of Trans-Alaska,Jining,Tokyo Gas are introduced respectively.Technologies in terms of hardware and software of the earthquake monitoring and early-warning system are also analyzed.Technologies of the hardware include vibrating parameters monitoring,fault displacement monitoring,pipeline leak monitoring and data transmission.Technologies of the software include vibrating parameters processing,auto alarming,as well as situation assessing and pipeline repairing consultation.
