Recently, quantitative risk assessment (QRA) has been widely used as a decision-making tool in the offshore industry. This study focused on analyzing dropped objects design of modern platform. A modified QRA procedure was developed for assessing production module protection against accidental external loads. Frequency and consequence analyses were performed using procedure. An exceedance curve ...

Road tunnels are vital infrastructures providing underground vehicular passageways for commuters and motorists. Various quantitative risk assessment (QRA) models have recently been developed and employed to evaluate the safety levels of road tunnels in terms of societal risk (as measured by the F/N curve). For a particular road tunnel, traffic volume and proportion of heavy goods vehicles (HGVs...

Pipeline is one of the safest and most cost-effective means transportation for hydrocarbons. However, hydrocarbon releases subsequent fires explosions, are presented as persistent events. Quantitative Risk Assessment (QRA) enables to address risk prevent these In this regard, different approaches have been proposed pipelines, but few studies focused on oil transportation. This paper presents a ...

The paper describes results of a European benchmark exercise in risk analysis of an ammonia storage facility. The comparison of results from the participants in the exercise showed significant differences, both in the frequencyand in the consequence assessment. The causes of some of these differences are discussed in the second part of the paper. This first part describes the project, the hazar...

In 1969, the Joint Committee on the Use of Antibiotics in Animal Husbandry and Veterinary Medicine in the United Kingdom warned that uncontrolled use of similar antimicrobials in humans and food animals might promote the emergence of resistant strains of foodborne bacteria that could endanger human health and compromise the effectiveness of antimicrobial therapies in human patients (Swann 1969)...

Quantitative risk analysis (QRA) of industrial facilities has to take into account multiple hazards threatening critical equipment. Nevertheless, engineering procedures able to evaluate quantitatively the effect of seismic action are not well established. Indeed, relevant industrial accidents may be triggered by loss of containment following ground shaking or other relevant natural hazards, eit...

AIMS We sought to examine the feasibility and reproducibility of a new video densitometric (VD) quantification of aortic regurgitation (AR) on aortography, and its long-term clinical impact. METHODS AND RESULTS Using dedicated video densitometry software, AR after TAVI was quantified, and inter- and intra-observer reproducibility was investigated in 182 aortograms of the Brazilian TAVI regist...

here have been many methodologies proposed for the risk assessment in the chemical process industries (CPI). Among them, the most notable ones are quantitative risk analysis, probabilistic safety analysis, worst-case methodology for risk assessment and optimal risk analysis. A critical review of these methodologies is available (1). The key points of these methods are: Quantitative risk analysi...

Quantitative risk assessment (QRA) modelling is increasingly used in food microbiology as a tool to evaluate health risks and to support the management of safe food production. Depending on the hazard and the process analysed, a QRA model may involve complex calculations: probability distributions are derived for the model parameters and the model is evaluated using specific risk analysis softw...

Hotspot identification (HSID) is the first and key step of the expressway safety management process. This study presents a new HSID method using the quantitative risk assessment (QRA) technique. Crashes that are likely to happen for a specific site are treated as the risk. The aggregation of the crash occurrence probability for all exposure vehicles is estimated based on the empirical Bayesian ...
