AIMS AND CONTENT

LEARNING OUTCOMES

The course is focused on various aspects of safety and security in industrial applications including: chemical plants, oil&gas, dangerous goods handling etc. Starting form reliability analysis, through Bayesian statistics, reliability modeling and simulation, failure analysis the course will guide the identification of possible risk factors and will presents the most promising methodological approaches. Two practical assignment will be given focusing on industrial incidents involving chemical spills and complex plants failures.

AIMS AND LEARNING OUTCOMES

The course addresses structurally the problem of the safety of industrial settlements and industrial plants in general, the introduction provides a basic framework and the connection with the notions learned in the Degree course with the possible completion of the existing "gap" . Part I addresses the structural patterns of cuts and collapses of industrial constructions, structures and carpentry as events often at the root of accidents. Through the analysis of theories and models, the student learns the "safe" design principles in the various scenarios considered. Part II addresses the consequences that industrial accidents can have on the environment and on people by emphasizing causal links and the interconnection between the structural, operational and human aspects of the incident phenomenon. The course is purely applicative with reference to industrial sectors considered to be "high risk" (chemical, nuclear, oil & gas, etc.).
