Probabilistic Hazard Assessment for Engineering Design Methodologies and Approaches to Evaluate Geohazards for Offshore Facilities

摘要

Probabilistic hazard analyses, which have been successfully used to evaluate various geohazards in both onshore and offshore environments, provide results that feed directly into project risk analyses. Evolving regulatory environments likely will incorporate more probabilistic and risk-based analyses in the future and this paper describes some of the key issues that need to be addressed in such studies and illustrates how these methodologies have been implemented successfully to address ground motion, fault displacement, and volcanic hazards in regulatory environments.
