Firefighting Emergency Capability Evaluation on Crude Oil Tank Farm

Firefighting emergency capabilities absorb more and more attention due to the sharp expansion of crude oil tank scale and frequent accidents of tank fire. An emergency capability evaluation model was developed towards crude oil tank farm based on the data of crude oil tank fire accidents and the concept of layers of protection analysis (LOPA). The model consists of four first-grade-index, fifteen second-grade-index, and fifty-eight third-grade-index. The analytic hierarchy process (AHP) was used to achieve the weight of each index at the different levels. The fuzzy evaluation was integrated to construct the emergency capability evaluation model. The model was validated in a petrochemical plant to identify the weaknesses of firefighting emergency system of the tank farm, and the countermeasures were provided based on the results to minimize the risks of the tank farm.
