Hazard and Operability (HAZOP) Analysis. A Literature Review
Journal of Hazardous Materials, 2010Hazard and operability (HAZOP) methodology is a Process Hazard Analysis (PHA) technique used worldwide for studying not only the hazards of a system, but also its operability problems, by exploring the effects of any deviations from design conditions. Our paper is the first HAZOP review intended to gather HAZOP-related literature from books, guidelines,

HAZOP Analysis Based on Sensitivity Evaluation
Safety Science, 2016Hazard and operability (HAZOP) analysis approach based on sensitivity evaluation is presented in this paper to ensure production safety in complex and large-scale chemical plants. In this approach, the sensitivity evaluation is introduced into HAZOP deviation analysis to measure the effect degree caused by each cause on the corresponding deviation.

A Systematic Formulation for HAZOP Analysis Based on Structural Model
Reliability Engineering and System Safety, 2014Abstract The combination of an automatic HAZOP analysis with a structural model was introduced to obtain a systematic procedure for hazard and mal-operations identification. There are three stages of the proposed procedure. The first stage was used to analyze the conventional hazard and mal-operations for each process unit, whereas the second stage ...

HAZOP Analysis of Formal Models of Safety-Critical Interactive Systems
, 2000 We consider methods for analysing interactive systems for operator errors leading to hazards. We model an industrial case study using formal methods and show how a HAZOP-based approach can be used to determine hazardous operator errors. The analysis can be used to motivate and guide redesign of the system to reduce the likelihood of such errors.

A Fuzzy Multi-Attribute HAZOP Technique (FMA-HAZOP): Application to Gas Wellhead Facilities
Safety Science, 2019 Hazard and Operability analysis (HAZOP) is a popular technique for hazard identification and risk ranking in hazardous facilities. Conventional HAZOP, however, has some drawbacks: (i) it considers a limited number of risk factors, i.e., only the ...

A Goal based methodology for HAZOP analysis [PDF]
, 2010 This paper presents a goal based methodology for HAZOP studies in which a functional model of the plant is used to assist in a functional decomposition of the plant starting from the purpose of the plant and continuing down to the function of a single node, e.g. a pipe section. This approach leads to nodes with simple functions such as liquid transport,

Automated HAZOP Revisited [PDF]
Chemical Engineering Research and Design, 2017 Hazard and operability analysis (HAZOP) has developed from a tentative approach to hazard identification for process plants in the early 1970s to an almost universally accepted approach today, and a central technique of safety engineering. Techniques for

Prioritizing HAZOP Analysis Using Analytic Hierarchy Process (AHP) [PDF]
Clean Technologies and Environmental Policy, 2016 Hazard and operability (HAZOP) analysis is one of the most widely used methods for process hazard analysis. However, the outcome of HAZOP analysis could result in identifying large number of hazards, thus posing a challenge for assessors to take actions ...
