Assessing Risk in the Supply Chain Using the Bowtie Method
(Mary Kay O'Connor Process Safety Center, 2016)
After a number of recent incidents involving the transportation and storage of hazardous materials, many industry end-users wish to understand their level of risk exposure during the supply chain. This exposure can either ...
Heavy gas concentration prediction on complex terrain using CFD with Monin-Obukhov similarity theory
(Mary Kay O'Connor Process Safety Center, 2019)
Under stable atmospheric conditions (i.e., low wind speed and low heat radiation), once heavy gases (e.g., CO2, H2S, LNG) release to the atmosphere, the gas clouds tend to stay near the ground for long period of time, ...
Measuring the Reliability of Safety Controls, Alarms, and Interlocks
(Mary Kay O'Connor Process Safety Center, 2016)
The risk analysis assumes a level of risk reduction provided by each of the safeguards, including safety controls, alarms, and interlocks (SCAI). After installation, SCAI equipment must be proven to meet the assumptions ...
CFD EXPLOSION SENSITIVITY ANALYSIS
(Mary Kay O'Connor Process Safety Center, 2016)
This paper describes the various activities involved in conducting a number of Quantitative Risk Assessments (QRA) to identify possible risk reduction measures for an offshore platform being located in an Arctic environment. ...
Lessons from Recent U.S. Onshore and Offshore Accident Investigations
(Mary Kay O'Connor Process Safety Center, 2016)
The U.S. oil and gas industry continues to experience major accidents, in spite of many regulatory, industry and company investigations, responses and improvement initiatives. These accidents have involved all segments of ...
Building Siting Screening Criteria for Structural Failure Hazards to Occupants
(Mary Kay O'Connor Process Safety Center, 2019)
Evaluation of occupied buildings for accidental explosion hazards at petrochemical facilities is a vital part of a process safety program and is a key element of facility siting. In some cases, buildings may be screened ...
Inherent Safety as a driver for business success in the Oil & Gas Industry
(Mary Kay O'Connor Process Safety Center, 2019)
Inherent safety is not a new concept and is recognized in the oil and gas industry following the works of Trevor Kletz [1] and others dating back to the 1970s. However, despite the progress made to date in the process ...
The Nature of Flammable Cloud Volumes in Semi-confined Environment under the Influence of Flow of Air
(Mary Kay O'Connor Process Safety Center, 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 ...
