An integration of human factors into quantitative risk analysis using Bayesian Belief Networks towards developing a ‘QRA+’

Quantitative Risk Analysis (QRA) is a standard tool in some high-risk industries (such as the on- and offshore exploration and production and chemical industry). Presently, existing knowledge concerning human error likelihood and human reliability assessment is insufficiently represented in QRAs. In this paper we attempt to implement the...

Improved method to calculate additional ramps explicitly (CARE2) in quantitative risk analysis for road tunnels

Article 13 of the EU Directive on minimum safety requirements for tunnels in the Trans-European Road Network states that a risk analysis, where necessary, shall be carried out. In the Netherlands, the risk of death for road users in a tunnel is calculated with a model for quantitative risk analysis, which is called “QRA-tunnels”. QRA-tunnels is...

Probability of large fire in a road tunnel; A Bayesian approach

Article 13 of the EU Directive on minimum safety requirements for tunnels in the Trans-European Road Network states that a “risk analysis, where necessary, shall be carried out” [1]. In the Netherlands, the risk of death for road users in a tunnel (internal risk) is calculated with a model for quantitative risk analysis, which is called “QRA...

Method to calculate additional ramps explicity (CARE) in quantitative risk analysis for road tunnels

Article 13 of the EU Directive on minimum safety requirements for tunnels in the Trans-European Road Network states that a risk analysis, where necessary, shall be carried out. In the Netherlands, the risk of decease for road users in a tunnel (internal risk) is calculated with a model for quantitative risk analysis, which is called “QRA-tunnels...

Risk reduction in road and rail LPG transportation by passive fire protection

The potential reduction of risk in LPG (Liquefied Petroleum Gas) road transport due to the adoption of passive fire protections was investigated. Experimental data available for small scale vessels fully engulfed by a fire were extended to real scale road and rail tankers through a finite elements model. The results of mathematical simulations...

An integrated approach for gas dispersion, gas explosion and structural impact analysis for an offshore production platform on the Dutch continental shelf

The design of an offshore gas production platform has been subjected to an extensive quantitative risk analysis in particular with regard to its resistance to gas explosions loads. It was demonstrated that integration of the physical and structural effects of a gas explosion in an early stage of the design results in a safe and economical design...

Developments in vapour cloud explosion blast modeling

TNT Equivalency methods are widely used for vapour cloud explosion blast modeling. Presently, however, other types of models are available which do not have the fundamental objections TNT Equivalency models have. TNO Multi-Energy method is increasingly accepted as a more reasonable alternative to be used as a simple and practical method....
