Pipeline replacement feasibility study : A methodology for minimizing seismic and corrosion risks to underground natural gas pipelines

ABSTRACT

This report completes the review of procedures used by the Southern California Gas Company to optimize decisions on pipeline replacement and repair. In addition to discussions with the Engineering Design Department, meetings were also held with representatives from System Planing, Transmission and Distribution. This study was conducted as a joint effort between EQE International and Cornell University. Partial support for this effort was received from the National Center for Earthquake Engineering Research. This report is comprised of two major parts (1) a report that discusses a plan for consideration of seismic and corrosion risk under a common program, and (2) a report that summarizes the development of improved corrosion leakage models for the Southern California Gas Company (Appendix B).(AU)
