Emergency System Survivability Assessment (ESSA)
Emergency System Survivability Assessment (ESSA)
We provide critical assurance that emergency systems remain functional during extreme scenarios through our Emergency System Survivability Assessment (ESSA).
What is ESSA?
ESSA evaluates the resilience of emergency equipment and systems—such as firewater pumps, emergency shutdown valves, and control rooms—to hazards like fire, explosion, and structural damage. The objective is to ensure these systems perform reliably when needed most.
ESSA Approach
We combine hazard scenario analysis with layout review and system redundancy evaluation to identify:
-
Vulnerabilities in emergency system locations and designs
-
Potential failure modes under credible hazardous events
-
Opportunities to enhance system robustness or provide redundancy
Our thorough assessments guide the implementation of measures that ensure system survivability.
