| description |
Potential failure modes analysis (PFMA)
is a process to systematically identify, describe, and
evaluate the ways in which a dam and its appurtenant
structures could fail under postulated loading conditions.
Since 2002, PFMA has been introduced as part of five-year
inspections under the U.S. Federal Energy Regulatory
Commission (FERC) regulations for nonfederal hydropower dams
in the United States. The PFMA is intended to provide an
understanding of how and why dams fail by looking at how
dams behave normally, learning to identify early signs that
something is wrong, understanding the hazards and risks
imposed by the dam, and being prepared for the unexpected
behavior that leads to failure. The World Bank has assisted
some countries in applying the PFMA for safety review of
major existing dams and found that the tool is useful in
prioritizing additional investigations needs and remedial
works in coordination with key stakeholders, including
owners, operators, and designers. This Technical Note
contains guidance for preparing PFMA terms of reference for:
(a) the FERC-based standard approach to PFMA; and (b) a
simplified PFMA approach. |
