Summary
This study introduces a maximum credible event approach for assessing liquefied natural gas (LNG) hazard zones, offering a framework to evaluate modeling conservatism in terminal development.
Area of Science:
- Chemical Engineering
- Risk Assessment
- Environmental Safety
Background:
- Hazard zone assessments for liquefied natural gas (LNG) terminal development are contentious.
- Discussions often focus on worst-case scenarios, leading to debates in regulatory processes.
Purpose of the Study:
- To present results from a maximum credible event (MCE) approach for LNG hazard zone analysis.
- To compare different modeling approaches used in the industry.
- To propose a set of base cases for evaluating modeling conservatism.
Main Methods:
- Utilized a maximum credible event (MCE) approach.
- Compared results from multiple hazard modeling tools.
- Reviewed existing experimental data and literature findings.
Main Results:
- The MCE approach provides a structured method for hazard zone assessment.
- Model comparisons reveal variations in predicted hazard zones.
- A proposed set of base cases aids in assessing modeling conservatism.
Conclusions:
- The MCE approach offers a valuable interim solution for LNG hazard zone assessment.
- Further large-scale experimental trials are needed to reduce uncertainty.
- The proposed base cases can help users evaluate the conservatism of selected models.
