Heat transfer modeling of high expansion foam application for vapor risk mitigation of Liquefied Natural Gas (LNG) spills
(Mary Kay O'Connor Process Safety Center, 2018)
The consumption of natural gas is expected to increase significantly over the next few decades due to much less carbon dioxide emission per unit of energy, when compared to other sources like oil or coal. This has also ...
Buckets to Disaster: What to Avoid in Making Critical Decisions
(Mary Kay O'Connor Process Safety Center, 2017)
This paper offers an approach to the development of techniques and tools to teach risk-based decision analysis and complex decision analysis to minimize the disastrous outcomes of critical decisions taking in the worlds ...
A Hazard Identification Framework of Complex Systems
(Mary Kay O'Connor Process Safety Center, 2018)
A chemical process facility is a highly complex system. The interactions among a small group of the functions, such as process, equipment, human, organizational functions, could split, merge or couple leading to a complex ...
Review: Overview of flame retardant additives, mechanism of flame retardancy and characterization techniques for polymer nanocomposites
(Mary Kay O'Connor Process Safety Center, 2017)
Fire retardancy of plastics is becoming increasingly important due to the widespread application of plastics in daily life and the subsequent fire hazard associated with it. A wide variety of flame retardant additives have ...
Modelling Ice and Wax Formation in a Pipeline in the Arctic Environment
(Mary Kay O'Connor Process Safety Center, 2019)
In the Arctic environment, fluid temperature in pipeline can drop below the freezing point of water, which causes wax and ice to form on pipeline surface. Solid formation on pipeline surface can lead to flow assurance and ...
System Dynamical Simulation of Risk Perception for Enterprise Decision-Maker in Communication of Chemical Incident Risks
(Mary Kay O'Connor Process Safety Center, 2016)
System Dynamical Simulation of Risk Perception for Enterprise Decision-Maker in Communication of Chemical Incident Risks
Multi-Objective Stochastic Optimization for Preventive Maintenance Planning
(Mary Kay O'Connor Process Safety Center, 2018)
Maintenance is an essential part of mechanical integrity programs and aims to prevent the occurrence of process safety incidents and costly unplanned shutdowns. Maintenance can increase the reliability of equipment in ...
A Resilience Index for Process Safety Analysis
(Mary Kay O'Connor Process Safety Center, 2016)
Qualitative risk analysis is focused on applying methods to prevent accidents in diverse process plants. The numerical number resulting in the QRA tells nothing about the ability for systems’ recovery if an upset related ...
Vapor Cloud Explosion Live Test and Data Analysis Development Program
(Mary Kay O'Connor Process Safety Center, 2015)
Vapor Cloud Explosions (VCE), an ever-present threat to the petroleum refining industry, create hazards to employees, equipment and production capabilities. To mitigate the effect of these hazards, effective designs for ...
Probabilistic Methods of Quantitative Risk Analysis: A Case Study with Bayesian Networks and Petri Nets Approach
(Mary Kay O'Connor Process Safety Center, 2016)
Conventional risk assessment methods such as Bow Ties have been incapable of capturing the dynamic nature of a system and hence have failed to properly predict the time dependent failure of barriers. Modifications made to ...
