Application of HAZOP Analysis Method in Vehicle Amusement Facilities
2020 3rd International Conference on Electron Device and Mechanical Engineering (ICEDME), 2020Problems in car rides often lead to more serious consequences, and cause social stability adverse effects. The safety of amusement facilities has always been the most important part in the design, construction and operation of amusement facilities. Therefore, starting from the safety issues of the amusement facilities, the HAZOP analysis method was ...

Hazard Analysis Using HAZOP: A Case Study
1993There is an increasing use of computing in safety related applications and ensuring that such systems are conceived, designed and produced with appropriate attention to safety is not easy. The process of identifying undesirable events and their consequences is known as hazard analysis.

Qualitative models of equipment units and their use in automatic HAZOP analysis
Reliability Engineering & System Safety, 2000Abstract The use of qualitative models in a support system for HAZOP analyses, in connection with an algorithm for finding the causes and the consequences of variable deviations, is described. The models use several representation structures among which mini-trees constitute the most important from the logical-functional point of view.

Layered digraph model for HAZOP analysis of chemical processes
Process Safety Progress, 2008AbstractProcess modeling has remained challenging in the area of automating hazard and operability (HAZOP) analysis of complex chemical processes. Even though signed digraph(SDG) model has been proposed and widely applied in various HAZOP expert systems in the past one decade, the limitations of SDG have not been recognized and discussed in literature.

An extended HAZOP analysis approach with dynamic fault tree
Journal of Loss Prevention in the Process Industries, 2015Abstract An extended hazard and operability (HAZOP) analysis approach with dynamic fault tree is proposed to identify potential hazards in chemical plants. First, the conventional HAZOP analysis is used to identify the possible fault causes and consequences of abnormal conditions, which are called deviations.

PHASuite: An Automated HAZOP Analysis Tool for Chemical Processes
Process Safety and Environmental Protection, 2005To aid human experts in conducting HAZOP analysis in a more thorough and systematic way, a software system called PHASuite has been developed. The work is divided into two parts. First, a knowledge engineering framework has been proposed and discussed in Part I of this two-part paper.

HAZOP Analysis System Compliant with Equipment Models Based on SDG
2013It is important to assess the risk in chemical plants. HAZOP is widely used in the risk assessment to identify hazard. An automatic analysis system is developed to perform HAZOP effectively. In this study, semi-automatic analysis system was developed by using the Signed Directed Graph (SDG) as a deviation in the behavior of the propagation of equipment.

Analysis of the HAZOP study and comparison with similar safety analysis systems
Gas Separation & Purification, 1989Abstract The hazard and operability (HAZOP) study is being used increasingly in the chemical and petrochemical industry as a tool for discovering safety problems in existing plants or in plants just designed or under construction. In this paper the procedure of the study is introduced and its relation to the fault-tree analysis and to the failure ...
