The course is devoted to the knowledge of techniques for reliability evaluation in process plants and to quantitative risk assessment in stationary process plants and multimodal HazMat transportation. Concerted application of skills in environmental and accident risk mitigation.
In-class lessons. Tutorials and numerical case-studies solved and critically discussed during the lessons. Self-directed team-work focused on acquring transversal knowledge to be assessed at the examination.
1.Introduction
Qualitative and quantitative risk assessment. General Risk Model. Unwanted events classification. Personnel and process safety. Complementing economics with safety. Relevant national and international regulations.
2.Occupational Safety
Statistics and accident frequency evaluation. Performance indicators of personnel safety. Human factor and risk determining factors. Occupational health and ergonomics.
3.Hazard Identification and Analysis
Gas, vapour and dust hazardous properties and their evaluation. Risk indicators. Hazard identification tools and application to case-studies. Fire, explosion, instability and reactivity. Sound and vibration: basic concepts.
4.Reliability engineering and frequency evaluation

In strict accordance with the official program issued by Polytechnic School, Genoa University - Academic year 2017-2018.
The oral final exam is set to evaluate student’s knowledge level, design and application abilities, as well as effective technical communication skills. It includes a critical discussion on the team case-study performed and completed during the lesson period. Subsequenly it is requested to discuss topics pertinent to human safety and plant reliability, damage and severity modelling, as well as to numerically solve a practical design problem pertinent the examined scenarios.
During the "Winter session" 3 examination dates are fixed (January, February and lessons break), 2 examination dates are fixed during the "Summer session" (June and July) and 2 in the "Autumn session" (September and lessons break). All exam dates are fixed strictly following the offcial scheduling of the Polytechnic School.
The aim is to provide knowledge and solving capabilities on safety and loss prevention issues in the process industry, with emphasis on reliability, environmental and personnel/process risk. The effectiveness assessment during the course development is performed by monitoring capabilities in numerical applications, lessons learned form incidents and team case-studies.
No formal requirements are foreseen; Chemical Plant and Chemical Engineering Principles represent useful background knowledge.
Lecture slides are delivered in reduced electronic format at the end of the pertinent semester. Supporting material for tutorials is provided during the lessons.
