Mao, Qi (author), Wang, Haiqing (author), Yang, M. (author), Hu, Jason (author)Safety instrumented systems(SIS) have been widely used in petroleum and chemical plants to detect and respond to dangerous events and prevent them from developing into accidents. The in-service time of SIS does not exceed its useful life is one of the crucial assumptions of IEC functional safety standards. The testing method recommended in the...journal article 2023

Iaiani, Matteo (author), Tugnoli, Alessandro (author), Cozzani, Valerio (author), Reniers, G.L.L.M.E. (author), Yang, M. (author)Offshore Oil&Gas facilities are attractive targets of intentional malicious attacks (security attacks) that may trigger cascading events (e.g., the release and dispersion of hazardous material and/or energy, fires, explosions) with consequences on people, environment, and assets. The severity of these consequences is potentially similar to...journal article 2023

Xu, Y. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author), Yuan, S. (author), Chen, Chao (author)Domino accidents are typical low-frequency and high-consequence events in chemical process industries. Applying quantitative risk assessment (QRA) in domino accident assessment is challenging due to the uncertainties in the escalation process. Meanwhile, the outcomes of QRA are subject to a certain degree of unreliability due to the...journal article 2023

Yang, M. (author), Chen, C. (author), Yuan, S. (author), Hermias, Jeffrel (author), Reniers, G.L.L.M.E. (author)We witness many severe accidents in different sectors worldwide every year, resulting in fatalities, injuries, environmental pollution, property loss, etc. Safety management aims to use interventions to prevent these undesired events and thus avoid different kinds of loss. Various interventions that have different safety performances and costs...report 2022

Lee, J. (author), Mitici, M.A. (author), Geng, S. (author), Yang, M. (author)When designing the maintenance of multi-component aircraft systems, we consider parameters such as safety margins (used when component replacements are scheduled), and reliability thresholds (used to define data-driven Remaining-Useful-Life prognostics of components). We propose Gaussian process learning and novel adaptive sampling techniques to...conference paper 2022

Chen, C. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author)An accident within a chemical plant may trigger escalation effects, leading to a catastrophic degradation of operating performance. Due to possible severe consequences of domino effects, safety and security measures are needed to prevent and mitigate domino effects in chemical industrial areas. However, safety and security measures may be...book chapter 2022

Chen, C. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author)Domino effects may be induced by both intentional and unintentional threats. To deal with possible intentional and unintentional domino effects, this chapter develops an integrated safety and security management framework. First, safety and security management principles are introduced to show the similarities and differences between safety...book chapter 2022

Chen, C. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author)Fires are the most common scenarios in domino effect accidents, responsible for most of the domino effects that occurred in the process and chemical industry. The escalation induced by fire is delayed since the build-up of heat radiation needs time. As a result, a fire-induced domino effect is a spatial–temporal evolution process of fires. To...book chapter 2022

Chen, C. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author)In a coupled domino effect, hazardous scenarios such as toxic release, VCE, and fire can simultaneously or sequentially occur. Chapters 2 and 3 only consider domino effects that are caused by fire or VCE. Therefore, this study develops a dynamic method called “Dynamic Graph Monte Carlo” (DGMC) to model the evolution of coupled domino effects and...book chapter 2022
