AIMS AND CONTENT

LEARNING OUTCOMES

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.

TEACHING METHODS

In-class lessons. Tutorials and numerical case-studies. Self-directed team-work.  

SYLLABUS/CONTENT

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

Theory of industrial reliability and elements of statistics. Frequency and probability.

Human and system reliability. Fault-tree analysis of complex systems. Case-study selection.

5.Severity and damage evaluation

Source term models.  Dispersion modelling of neutral and dense gas and cold jet. Fire scenarios modelling (flash fire, pool-fire, jet fire, fireball, ventilation controlled fire). Explosion modelling (vapour cloud explosion, physical explosion, runaway, cold and hot BLEVE).  Notable major accidents and relevant lessons.

6.Quantitative Risk Assessment

Local, individual and social risk. Damage models (threshold and probit approach). Risk acceptability criteria. Risk mitigation and design of emergency relief systems. Land use planning.  Risk in multimodal HazMat transportation. HSE risk management. Risk perception.

EXAM DESCRIPTION

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.

ASSESSMENT METHODS

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.
