Need: Much of the current seismic practice can be traced to research conducted in the 1970s to develop design criteria and procedures for the Trans-Alaska oil pipeline. The major natural gas pipeline operators in California have implemented many of the procedures in these guidelines, in one form or another. The recognition of credible seismic hazards in other parts of the United States has been the primary driver for extending current practices in California to the rest of the United States. The experience in designing pipelines in seismically active regions of the United States has also provided a basis for specifying pipeline seismic design practices in other parts of the world.
Result: This project was initiated by PRCI to provide current seismic guidelines for the design and assessment of natural gas transmission pipelines. These guidelines were refined using two rounds of review by outside technical experts in 1999 and 2000. The PRCI ad hoc steering group for the project also provided regular input regarding the scope and technical content for these guidelines. A decision was made in late 2000 to expand the scope to liquid hydrocarbon pipelines (crude oil and refined products) based upon the identical analytical treatment of seismic design and assessment of these types of pipelines.
Benefit: The present guidelines are intended to be an update of the 1984 ASCE guidelines relating to buried pipelines transporting natural gas and liquid hydrocarbons. To that end, preparation of these guidelines attempts to take full advantage of recent research findings with respect to soil loading on buried pipelines, acceptable strain-based pipeline limit states, and current analysis tools. To the extent possible, these guidelines have been stated in a concise manner with minimal discussion so as to keep the main text clear and concise. More in-depth discussions of the bases for recommendations in these guidelines are provided in a comprehensive Commentary at the end of this document. These guidelines are the product of considerable peer review by experts within the pipeline industry, key investigators at various research organizations, and consultants providing seismic design and assessment services to natural gas pipeline operators. There continue to be advancements in understanding pipeline behavior and seismic hazard definition. It is anticipated that these guidelines will be updated as ongoing research is incorporated into actual practice.
