Abstract
Describes a novel technique for the feasible integration of process design and risk assessment using commercial simulators with the goal of carrying out risk-based process safety management of an existing gas oil separation plant (GOSP). For integration of these two different natures, the concept of static inventory was deduced in order to adjust the dynamic behavior of the fluid in process simulation to accident simulation, considering the flow rate and release duration of the fluid in case of an accident.
Particularly for the gas treatment unit (GTU) among the various subsections of the GOSP process, this methodology attempts to assess the potential risk at the preliminary design stage and modify the process design of the existing process to alleviate the major hazard recursively identified during rigorous quantitative risk assessment (QRA).

Abstract
The inherent complexity of the processes and the volatile nature of petroleum products compel the petroleum industry to continually seek and develop tools and techniques to identify, evaluate, and mitigate potential risks that can negatively impact their process operations. Additionally, government agencies and nonprofit professional societies guide the petroleum industry with regulatory guidelines, standards, and recommended best practices. The industry and these agencies and societies work to improve operational management, to ensure safe working conditions, and to minimize risk of all kinds, so that if failures occur, damage is contained within tolerable limits. The currently used of both qualitative and quantitative risk assessment tools fall short in identifying and ranking potential risks in the petroleum industry and they fail to demonstrate that risks have been reduced as low as reasonably practicable (ALARP). Moreover, the tools are limited to large, complex, and expensive studies. Because accidents due to both human errors and electromechanical failures still occur and result in various consequences, critics have raised concerns about the petroleum industry's safety and risk mitigation credentials and question its ability to prevent major accidents.
The purpose of this research is to introduce new methods that provide more detailed and structure information to decision makers. They are more robust and easier-to-use so that novice engineers can successfully apply them without experts' need. This dissertation employs the publication option, where the research results are reported by presenting the text of five journal-conference publications."

Abstract

The majority of existing methods of risk assessment of trunk oil pipelines is based on probability and classical set theory. These methods do not take into consideration the fact that any complex system, such as trunk oil pipelines, is a dynamic system with a set of uncertain data. The results of risk assessment, obtained by conventional methods, don’t reflect the real situation about the condition of system. Authors offer a methodical approach to identification of risk factors sources and assessment of the level of risk based on system analysis and fuzzy set theory.
The approach makes it possible to receive output conclusion about risk level in dynamic area of a complex system. The principles of fuzzy logic in the evaluation of diverse parameters of risk factors allow bringing them to a qualitative common denominator. As a result, we can perform comparative research of separate risk factors and also summarize them for assessment of current risk level of trunk oil pipelines. We reviewed causes of incidents and failures on trunk oil pipelines and have identified the most important risk factors that have greatest consequences. Risk factors in our method are determined by fuzzy set rules, which are a result of data analysis (accident reports, failure records for the similar pipelines) and expert’s evaluation of related input parameters. Risk factors and their parameters are classified in accordance with their relation to different environment and life-cycle stages. The article presents an example of evaluation of risk factor . Consequently, the indicator of risk factor was calculated in accordance with procedure of Mamdani fuzzy inference system (using the MATLAB Fuzzy Logic Designer). This method of risk assessment brings high opportunities for identification of the pipeline segments, where the risk level is most probably high and helps the decision maker to take remedial actions to mitigate potential risks. The operator can more effectively manage resources and improve efficiency of actions. Ability to reflect the current risk level is key advantage of our approach to risk assessment of risk management of trunk oil pipelines

Abstract
Describes the practical application of the Failure Mode and Effect Analysis method to assess the operational reliability of oil refinery equipment, a major problem for oil-producing regions and countries. Oil refineries are hazardous industries. Consequently, the construction, adaptation and testing of effective risk analysis methods is important. The solution to this problem provides the basis for corrective actions to reduce the probability of damage from accidents to humans and the environment. The method is based on the detection probability of inconsistencies and involves elaborate ways to increase the reliability and security through risk analysis method.
The approbation is performed for the Failure Mode and Effect Analysis method to assess the reliability based on the detection of defects typical to oil and gas facilities. The basic steps of the Failure Mode and Effect Analysis method are provided and show the possible options for scaling required to obtain quantitative risk assessments. The result was the quantitative risk assessment for oil transportation facilities. The supporting method for quantifying risk in emergency situations on the equipment are encouraged to use a fuzzy logic approach. The paper describes the main steps of this approach, demonstrating its applicability and the possibility of formation for quantitative estimates of the hazards of various defects in the equipment.
