Tan, Xinxin (author), Xiao, Shenbin (author), Yang, Yu (author), Khakzad, Nima (author), Reniers, G.L.L.M.E. (author), Chen, Chao (author)Frequent unpredictable earthquake disasters such as the Turkey Earthquake in 2023 pose an increasing threat to oil tank farms since they may trigger major accidents and domino effects, resulting in casualties, economic losses, and environmental pollution. Unpredictable earthquakes are definitely difficult to prevent and thus resilience...journal article 2024

Cheraghi, Morteza (author), Reniers, G.L.L.M.E. (author), Eslami Baladeh, Aliakbar (author), Khakzad, Nima (author), Taghipour, Sharareh (author)Risk-based techniques such as risk graph and Layer of Protection Analysis (LOPA) are used to determine the Safety Integrity Level (SIL) of safety instrumented functions to ensure that risk is reduced to a tolerable level. However, these techniques have some drawbacks. For instance, they need absolute and precise numbers to evaluate SIL...journal article 2024

Khakzad, Nima (author), Chen, Chao (author), Reniers, G.L.L.M.E. (author), Amyotte, Paul (author)Effective firefighting and evacuation are integral parts of emergency response plans in process plants, which play a key role in protecting human lives and assets in the event of major fires. Given sufficient firefighting resources, firefighters would suppress all the burning vessels and cool off all the exposed vessels in order to contain the...journal article 2023

Khakzad, Sina (author), Yang, M. (author), Lohi, Ali (author), Khakzad, N. (author)Oil and gas pipelines play a key role in the safe and efficient delivery of energy resources around the world. Crude oil by itself is not corrosive, but oil extracted from geological reservoirs is accompanied by varying amounts of water and acidic gases such as carbon dioxide (CO2), which can form a corrosive combination. Estimating the...journal article 2022

Lee, Shenae (author), Khakzad, Nima (author), Schmitz, P.J.H. (author), Reniers, G.L.L.M.E. (author), Habrekke, Solfrid (author), Paltrinieri, Nicola (author)Hazardous events in process plants like the leakage of dangerous substances can result in severe damage, and such an event is often defined as the TOP event of a fault tree analysis (FTA) in a quantitative risk analysis. The TOP event probability can then be calculated if the basic events probabilities are provided. These probabilities are often...journal article 2022

Zinetullina, Altyngul (author), Yang, M. (author), Khakzad, Nima (author), Golman, Boris (author), Li, Xinhong (author)The emergent hazards of chemical process systems cannot be wholly identified and are highly uncertain due to the complicated technical-human-organizational interactions. Under uncertain and unpredictable circumstances, resilience becomes an essential property of a chemical process system that helps it better adapt to disruptions and restore...journal article 2021

Chen, C. (author), Reniers, G.L.L.M.E. (author), Khakzad, Nima (author), Yang, M. (author)Due to the COVID-19 pandemic in 2020, the trade-off between economics and epidemic prevention (safety) has become painfully clear worldwide. This situation thus highlights the significance of balancing the economy with safety and health. Safety economics, considering the interdependencies between safety and micro-economics, is ideal for...journal article 2021

Swuste, P.H.J.J. (author), van Nunen, K.L.L. (author), Reniers, G.L.L.M.E. (author), Khakzad, N. (author)Major accidents in Western countries, receiving a lot of media attention in the 1970s, are starting point for research into internal and external domino effects in the chemical and petrochemical sectors and clusters. Initially, these reports are published by government institutions and government-related research centers. With the upcoming...book chapter 2021

Chen, C. (author), Khakzad, Nima (author), Reniers, G.L.L.M.E. (author)Vapor cloud explosion (VCE) accidents in recent years such as the Buncefield accident in 2005 indicate that VCEs in process plants may lead to unpredicted overpressures, resulting in catastrophic disasters. Although a lot of attempts have been done to assess VCEs in process plants, little attention has been paid to the spatial-temporal...journal article 2020

Abrishami, S. (author), Khakzad, Nima (author), Hosseini, Seyed Mahmoud (author)Bayesian Network (BN) has been increasingly exploited to improve different aspects of Human Reliability Analysis (HRA), resulting in a new generation of HRA techniques, known as BN-HRA models. However, validating and evaluating the accuracy of BN-HRA models is still a challenging task. In this study, we have assessed and compared the...journal article 2020

Reniers, G.L.L.M.E. (author), Landucci, G. (author), Khakzad, Nima (author)Engineering risk management is comprised of managing operational safety risks on the one hand and managing physical security risks on the other. Although some basic management principles are obviously the same for both safety and security, some important conceptual and calculation differences exist, as is explained in this paper. For instance...journal article 2020

Chen, C. (author), Reniers, G.L.L.M.E. (author), Khakzad, Nima (author)In the chemical industry, multi-hazard (toxic, flammable, and explosive) materials such as acrylonitrile are stored, transported, and processed in large quantities. A release of multi-hazard materials can simultaneously or sequentially lead to acute toxicity, fire and explosion. The spatial-temporal evolution of hazards may also result in...journal article 2020

Cheraghi, Morteza (author), Eslami Baladeh, Aliakbar (author), Khakzad, N. (author)Hazard and Operability analysis (HAZOP) is a popular technique for hazard identification and risk ranking in hazardous facilities. Conventional HAZOP, however, has some drawbacks: (i) it considers a limited number of risk factors, i.e., only the frequency and the severity of hazards; (ii) it assumes equal weights for the risk factors, thus...journal article 2019
