Inherent Safety of Dikes Against Catastrophic Failure of Storage Tanks
(Mary Kay O'Connor Process Safety Center, 2002)
It is industry practice to provide passive containment (dikes) of storage tank equivalent to 110% of the capacity of the tank. This standard is sufficient for containment of small to moderate leaks. However, it is generally ...
Chemical Plant Security: National Security for the Chemical Industry
(Mary Kay O'Connor Process Safety Center, 2002)
Probabilistic Fault Tree Analysis
(Mary Kay O'Connor Process Safety Center, 2002)
Are We Missing any Detonations?
(Mary Kay O'Connor Process Safety Center, 2016)
The common rift between academia and industry has existed in all fields of engineering. However, ultimately the rift can be seen as more of a lag; it is not so much a question of “academia is not the real world” but rather ...
HAZOPs in a Cash Constrained Enviornemnt
(Mary Kay O'Connor Process Safety Center, 2016)
Year 2015 has been another difficult year for the oil and gas (O&G) industry. For the upstream industry, low prices of oil have resulted in operating companies making drastic changes to their economic canvas due to shrinking ...
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 ...
BRAIN-CENTERED HAZARDS: RISKS & REMEDIES
(Mary Kay O'Connor Process Safety Center, 2016)
Knowing that risk is created by exposure to hazards, all members of the workforce have been enlisted to become “hazard recognizers.” Front-line workers and leaders alike are taught to observe their work environments for ...
General Method for Uncertainty Evaluation of Safety Integrity Level (SIL) Calculations
(Mary Kay O'Connor Process Safety Center, 2016)
The IEC 61511 standard requires a verification calculation that a proposed design for a safety instrumented function (SIF) achieves the desired safety integrity level (SIL). The evaluation of the safety integrity level of ...
Pros & Cons of Electronic Marshalling for a Safety System
(Mary Kay O'Connor Process Safety Center, 2016)
Electronic Marshalling represents a new technology for connecting hard wired inputs and outputs to a control system. In lieu of using a twisted pair of shielded wires There are specific and obvious advantages to using ...
CCPS’s Vision 20/20: Improving YOUR vision so WE ALL can see better
(Mary Kay O'Connor Process Safety Center, 2016)
Vision 20/20, developed by the Center for Chemical Process Safety (CCPS), looks into the not- too-distant future to describe how great process safety is delivered when it is collectively and fervently supported by industry, ...
