Practical Considerations for Overfilling Scenario Application
(Mary Kay O'Connor Process Safety Center, 2019)
As a result of the BP Texas City explosion, industry recognized overfilling as one of the most important overpressure scenarios to be considered. Atmospheric release of flammable liquids above their flash point is no longer ...
Analyzing Procedure Performance using Abstraction Hierarchy: Implications of Designing Procedures for High-risk Process Operations
(Mary Kay O'Connor Process Safety Center, 2019)
Standard operating procedures (SOPs) are a vital element of everyday operations in chemical process industries. Incident investigations also indicate that a majority of adverse events in the processing operations are ...
Exploration of relationships between safety performance and unsafe behavior in coal mining processes
(Mary Kay O'Connor Process Safety Center, 2019)
It is well known that safety performance is differentiated to two components, namely, safety compliance and safety participation. However, relationships between safety performance and unsafe behavior were barely explored. ...
A Practical Approach to Preventing Systematic Error in the Maintenance of Instrumented Safeguards
(Mary Kay O'Connor Process Safety Center, 2019)
Instrumentation and electrical (I&E) maintenance is typically managed using site-wide policies, practices, and procedures. Since I&E equipment is part of the control system and nearly every other layer of protection, the ...
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 ...
Relationship between Human-Managerial and Social-Organizational Factors for Industry Safeguards Project: Dynamic Bayesian Networks
(Mary Kay O'Connor Process Safety Center, 2019)
This methodology intends to identify the Relationship Network between Human-Managerial and Social-Organizational Factors considering the Dynamic behaviour and Work Environment to build preventive actions based on the ...
Crosswalk of Human Reliability Methods for Offshore Oil Incidents
(Mary Kay O'Connor Process Safety Center, 2019)
Human reliability analysis (HRA) has long been employed in nuclear power applications to account for the human contribution to safety. HRA is used qualitatively to identify and model sources of human error and quantitatively ...
PPE – Can you have too much of a good thing?
(Mary Kay O'Connor Process Safety Center, 2019)
Specifying Personal Protective Equipment (PPE) after a hazard has been identified is a critical aspect of a facility’s ability to protect their workers. In a chemical manufacturing facility, manual operations and maintenance ...
Fire and Gas Hazard Mapping Continues to Require Engineering Judgment
(Mary Kay O'Connor Process Safety Center, 2019)
It is becoming increasingly common to use computer applications and software tools to aid engineers in designing fire and gas detector layouts. These tools help designers optimize layouts as well as verify, quantify and ...
Life After a Risk-Based Inspection Implementation
(Mary Kay O'Connor Process Safety Center, 2019)
Many chemical and oil and gas organizations have Risk-Based Inspection (RBI) programs in the form of the American Petroleum Institute (API) API Recommended Practice (RP) 580 Risk-Based Inspection program. Numerous organizations ...
