Modelling of BP Texas City refinery accident using dynamic risk assessment approach

Hazardous events in membrane bioreactors – Part 2: Impacts on removal of trace organic chemical contaminants

“…The validation process is expected to capture not only normal operational conditions but also "hazardous event" conditions, where water quality is outside specification potentially posing an elevated exposure risk [1,2]. Risk assessments focused on hazardous events have been applied for a wide variety of applications, including the management of water borne diseases [3] and in the modelling of oil refinery accidents [4]. The assessment of hazardous events is a key philosophy in the approach to water quality risk assessment used by the World Health Organisation (WHO) for the development of Water Safety Plans [5] and is described in the WHO Guidelines for Drinking Water Quality [6].…”

Introducing ASIL inspired dynamic tactical safety decision framework for automated vehicles

“…As processes become complex, risk assessment made for a particular phase may not be appropriate for another phase of the system application [13]. While risk assessment has been conducted in the chemical process industry for many years, history has shown that similar accidents repeat themselves (Bhopal 1984 [14] and Texas City 2005 [15]). This has led to several efforts towards a dynamic approach to risk assessment in the chemical process industry [16].…”

“…Alternatively, a non-Bayesian approach to probability updating can be applied which requires real-time parameter values and status health of the system [17], [23]. The versatility of the DRA method for chemical process systems has been demonstrated by applications in real life cases like BP Texas Refinery accident [15], off shore drilling [24] and BP Deepwater Horizon accident [25]. However, the DRA approach too falls short in certain aspects.…”

Risk analysis of emergent water pollution accidents based on a Bayesian Network

“…So bridges are the main locations where personnel and trucks are closed. Bridges pose a potential threat to the water quality in an emergent pollution accident (Kalantarnia et al, 2010).…”
