High Resolution Quantitative Risk Analysis - An Advanced Management Tool
(Mary Kay O'Connor Process Safety Center, 2000)
Typical deliverables of a classical quantitative risk analysis (or QRA) effort are individual risk and societal risk data. Individual risk within the context of such a classical QRA is defined as the frequency or probability ...
SS3G: An Integrated Risk Analysis Program Using Engineering Principles for Building Damage
(Mary Kay O'Connor Process Safety Center, 2001)
We announce the development, with the support of an industrial consortium, of an extensive new integrated modeling system named SS3G (Safe-Site 3rd Generation). This system is the first such risk analysis program to provide ...
MODELING INDOOR DISPERSION OF AEROSOLS OR VAPORS AND SUBSEQUENT VENTED FIRE OR EXPLOSION
(Mary Kay O'Connor Process Safety Center, 2000)
Considerable developmental work has gone into modeling dispersion of accidental outdoor releases; less has been applied to indoor releases. Indoor dispersion is characterized by the influence of a ventilation system and ...
Non-Conformance of Existing Pressure Relief Systems With Recommended Practices: A Statistical Analysis
(Mary Kay O'Connor Process Safety Center, 2002)
This article presents a statistical analysis showing that the pressure relief systems on nearly half of the equipment in the oil, gas, and chemical industries lack adequate overpressure protection as defined by recognized ...
Significant Event Elimination Program Overview
(Mary Kay O'Connor Process Safety Center, 1999)
This paper presents an overview of the Significant Event Elimination (SEE) Program. The objective of the SEE Program is to eliminate the reoccurrence of events which have had the most significant impact, or potential for ...
A Robust Sensor Fault Diagnosis System Using Neural Networks and a Dynamic Process Model
(Mary Kay O'Connor Process Safety Center, 2001)
Back propagation (BP) neural networks are applied for reactor fault diagnosis. Analyzed is the output prediction error between a neural network model and an independent dynamic process model, which serves as a residual for ...
Effect of Air in the Thermal Decomposition of 50 wt.% Hydroxylamine/water
(Mary Kay O'Connor Process Safety Center, 2001)
This paper presents experimental measurements of the thermal decomposition reaction of 50 wt% hydroxylamine/water (HA) in an oxygen-free environment using an APTAC calorimeter. Overall kinetics, onset temperatures, heats ...
Explosion Risk Assessment, How the Results Vary With the Approach Chosen
(Mary Kay O'Connor Process Safety Center, 2001)
Within explosion risk assessment there is a range of methods being applied. Various kinds of guidelines and empirical models, where a lot of subjective assumptions will have to be done, are still widely used onshore. For ...
Process Safety Management in the Pipeline Industry: Parallels and Differences between the Pipeline Integrity Management (IMP) Rule of the Office of Pipeline Safety and the PSM/RMP Approach for Process Facilities
(Mary Kay O'Connor Process Safety Center, 2002)
In 2001, the federal Office of Pipeline Safety promulgated its Pipeline Integrity Management Rule for hazardous liquid pipelines. A similar rule for gas pipelines is due in 2002. These rules derive from formal risk management ...
Mitigate the Hazards of Emergency Atmospheric Venting by Steam Injection
(Mary Kay O'Connor Process Safety Center, 1999)
During major plant upsets, it is often necessary to safely relieve the process fluids contained in process equipment. The relieved vapors may be flammable and/or toxic, and the vapor clouds may be within the explosive ...
