اسلاید 1: Hazards And Operability Analysis (HAZOP)Saeid Ahmadi

اسلاید 2: When to Use HAZOPHAZOP is a hazards identification tool.It is best used as late as possible with a new design, in order to be as complete as possible.With an existing facility it can be used at any time.HAZOP can also be used for analyzing operating instructions and procedures so thatsources of human error can be identified (and corrected).

اسلاید 3: AdvantageHAZOP is very thorough, because you force yourself to painstakingly examine most aspects.HAZOP is the most widely used methodology used in the world today as a tool for hazards identification.

اسلاید 4: DisadvantageHAZOP is very time consuming and costlyIf not set up correctly and managed properly, it can be ineffectiveNeeds Leadership by an Expert in the field of HAZOP.

اسلاید 5: مطالعه عملیات وخطر HAZOPمطالعه HAZOP معمولا در مراحل زیر از چرخه عمر سیستم انجام می شود: مرحله ایده وتفکرمرحله طراحی جزئیاتمرحله عملیات

اسلاید 6: BasisSimulates abnormal situations by using Guidewords applied to Parameters and Operations to create Deviations.

اسلاید 7: Methodology1. Collect applicable documents and drawings, e.g., process flow diagrams, piping and instrument diagrams, plot plans, etc.2. Break facility down into manageable sections (Nodes).Break P&IDs down into Nodes.Nodes are equipment items (or numbers of items).If nodes are too small you can loose sense of analysis and incur excessive repetition.If nodes are too large, hard to handle, becomes confusing.
