Pacific LNG Project Bolivia, Chile Alumni Student Careers Forum Earth and Planetary Science 325 McCone Hall October 22, 2008 Presenter: Peter Yen Bechtel -San Francisco Technical Evaluation of Alternative Routes APPROACH 1. Division of alignment into broad physiographic provinces (Eastern Lowlands, Basin Ranges, Altiplano, Western Cordilleras, Western Coastal Region/Desert). 2. Evaluate major hazard categories in each province (Seismicity, Volcanism, Quaternary Faulting, Unstable Foundation Conditions). 3. Identify the zone of influence of each hazard type within the zone. 18
Technical Evaluation of Alternatives APPROACH (cont d) 4. Quantify the hazard by rating (1. Low, 2. Moderate, 3. High). 5. Use a matrix for evaluation of hazard rating and length of pipeline subject to hazard. 6. Incorporate hazard rating maps into the GIS system. 7. Normalize hazard rating into engineering criteria. 8. Select preferred alternative route. 19
