A Functional approach to HAZOP studies
This paper presents a functional approach to HAZOP studies in which the plant is divided along strictly functional lines starting from the purpose of the plant and continuing down to the function of a single node, e.g. a pipe section. The approach leads to nodes with simple functions such as liquid transport, gas transport, liquid storage, gas-liquid contacting etc. From the functions of the no...
متن کاملApplying HAZOP to Software Engineering Models
HAZOP is a powerful hazard analysis technique which has a long history in process industries. As the use of programmable electronic systems becomes more common, it is clear that there is a need for a HAZOP method which can be used effectively with such systems. This paper describes several attempts to derive such a process, and identifies some requirements which must be met by any PES HAZOP pro...
متن کاملHazop Studies Using a Functional Modeling Framework
In this paper we present a HAZOP Assistant based on D-higraphs, a functional modeling technique that gathers functional and structural information of the process under study. The Assistant and the methodology are presented and applied to an industrial case: H2S absorption and DEA regeneration. Its results are compared with other existing techniques showing that the Assistant fills the gaps and ...
متن کاملIntegration of HAZOP and FMEA analysis
Some results of the implementation of a new support tool for automated hazard analysis are presented in this paper. We describe in detail the further progresses on the application of intelligent systems to the hazard analysis and especially to the HAZOP and FMEA analysis. A previously developed program, that allows the automatic generation of the report of the HAZOP analysis as regards the dete...
متن کاملAutomating HAZOP studies using D-higraphs
In this paper, we present the use of D-higraphs to perform HAZOP studies. D-higraphs is a formalism that includes in a single model the functional as well as the structural (ontological) components of any given system. A tool to perform a semi-automatic guided HAZOP study on a process plant is presented. The diagnostic system uses an expert system to predict the behavior modeled using D-higraph...
متن کاملIntegration of interlock system analysis with automated HAZOP analysis
The paper details the integration of a method for the analysis of interlock systems with a software support system for HAZOP analysis. The proposed software aims to enhance the potential of HAZOP in terms of depth and ef®ciency of the analysis. This enhancement is reached through the continuation of the hazard and operability analysis, limited to a group of events which may hold high risks for ...
