(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2019)In the Explosion Risk Analysis (ERA), ventilation and dispersion calculations using Computational Fluid Dynamics (CFD) are usually considered when the level of confinement and congestion cannot be neglected. As far as the ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2015)Hazard evaluations, also called process hazard analysis (PHAs) have been performed formally in gradually improving fashion for more than five decades. Methods such as HAZOP and What-If+ Analysis have been developed and ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2019)Within the context of a quantitative risk analysis (QRA), the two main constituents used to describe petrochemical risks are, and have always been, consequence and probability. The consequences of hazardous material accidents ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2017)Statistics from several industry and government sources indicate that the OSHA PSM process safety incident frequency has dropped dramatically. However, the improvement trend seems to have plateaued. It has also been noted ...

-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 1999)The process industries have been using the hazard and operability (HAZOP) study and design specification checklist methods to analyze processes for several years. Both can be utilized to provide adequate safety analysis ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 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 ...

-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2016)Not all pipelines are created equal. Pipelines have different characteristics, and would therefore show different levels of integrity and fail differently. The failure mode and cause of a given pipeline depends on several ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2016)In-situ burning has been considered as a primary spill response option for oil spills since offshore drilling began in the Beaufort Sea (1970s). Since then, many studies and tests have been performed but researchers are ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2015)Intrinsic to the computer modeling of explosions and fires is the concept of flammability limits. Conventionally, the term “flammability limit” is defined loosely as the concentration limits beyond which flame propagation ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2018)As the chemical industry has developed, the use of toxic substances has increased, and leakage accidents have increased. Among various substances, hydrogen fluoride (HF) and ammonia (NH3) are representative materials for ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2001)With the availability of powerful computers and continued reduction in computing cost, it is routinely possible to calculate the physico-chemical properties of chemicals. This paper is an overview of state-of- the-art ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2001)Risk assessment for offshore facilities began shortly after the Piper Alpha incident in 1988. At this time, the UK Health and Safety Executive issued rules for Safety Cases for offshore installations. Safety Cases are now ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2017)When the ambient temperature is below freezing point, ice may form in the oil transportation pipelines, which can cause flow assurance issues, such as restricting flow path or even plugging the pipeline. Ice plugging was ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2019)Protective systems failure can be catastrophic, and originates in management failure. These systems rely on a document-based approach, which involves handling disjointed artifacts that are expensive to maintain and may ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2019)CCPS defines Operational Discipline as “the execution of operational and management tasks in a deliberate and structured manner.” Put more succinctly, operational discipline can be defined as doing the right thing when no ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2017)In today’s business environment, process automation is dramatically changing the way console operators learn and perform. Console operators have more control loops than ever to manage, while processes and control systems ...

Opportunities and challenges of high-level visualization technology in process operations and safety (Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2019)The rapid development in high-level visualization technology in recent years has created tremendous opportunities for enhancing all facets of industry. Augmented reality (AR), mixed reality (MR), and virtual reality (VR) ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2015)Sectioning is one of the key mitigation strategies in pipeline transport of liquid hydrocarbons. The valves located along pipelines reduce the maximum volume that may be spilled, decreasing economic, social and environmental ...
