A Study of Safety Culture Assessment Framework for Process Industries and Its Application to a Bayesian Belief Network Analysis
(2016-08-08)
Investigations of major catastrophes in process industries have revealed that deficiency of good safety culture is one of the underlying causes of such disasters. Not only has safety culture been recognized as a root cause, ...
Methods to Improve Process Safety Performance through Flange Connection Leak Prediction and Control
(2014-08-08)
Process safety is a task of preventing leaks. Leak prevention is critical because pressure vessels and piping assets in chemical plants are fabricated from materials which have limited corrosion resistance. When corrosive ...
Well Integrity Diagnostics for Sustained Casing Pressure and Faulty Gas-Lift Valve Based on Pressure Transient Modeling
(2014-10-20)
A problem frequently present in the oil and gas industry is the difficulty of measuring well integrity parameters; particularly, for high-pressure high-temperature wells. For this reason, many relevant parameters, indicators ...
Optimize Ventilation Systems in Confined Workplaces Using Computational Fluid Dynamics
(2018-04-30)
Chemical industry and society always want to eliminate the damage to the environment and lower the casualty if an incident occurs. Finding a more efficient and effective way to achieve this goal is now more critical than ...
Application of Computational Fluid Dynamics for Liquefied Natural Gas Pool Spreading and Vaporization on Water
(2016-04-22)
Liquefied Natural Gas (LNG) is a cryogenic liquid consisting predominantly of methane compressed to 1/600th of its gaseous volume for transportation. A release of LNG on water during marine operations can occur due to ...
Safety-oriented Resilience Evaluation in Chemical Processes
(2012-02-14)
In the area of process safety, many efforts have focused on studying methods to prevent the transition of the state of the system from a normal state to an upset and/or catastrophic state, but many unexpected changes are ...
Modeling of LNG Pool Spreading and Vaporization
(2012-11-20)
In this work, a source term model for estimating the rate of spreading and vaporization of LNG on land and sea is introduced. The model takes into account the composition changes of the boiling mixture, the varying ...
Developing Process Safety Indicators for Organizational Factors in Petrochemical Industries
(2015-07-09)
Most major process safety incidents are preventable and can be avoided as shown in several incident investigation reports. Moreover, these reports indicated that these incidents were certain to occur as shown from the ...
Mathematical Programming Formulations for the Optimal Placement of Imperfect Detectors with Applications to Flammable Gas Detection and Mitigation Systems
(2014-11-13)
The placement of detectors in mitigation systems is a difficult problem usually addressed in the industry via qualitative and semiquantative approaches. Simplifications are used to circumvent difficulties regarding problem ...
Development of a Safety Management System for Drilling and Servicing Operations within OSHA Jurisdiction Area for Texas
(2015-11-05)
Workers of oil and gas extraction industries are exposed to different safety hazards, resulting in fatality rates seven times greater than that of the average U.S. worker. However, oil and gas drilling and servicing ...
