Training objectives
- The aim of the course is to provide basic knowledge on decommissioning engineering and management for both industrial and civil sites.
Decommissioning activities represent nowadays an autonomous engineering discipline covering the organizational, administrative and technical aspects relevant to the temporary shut-down (mothballing) of a site for revamping, renovation, enlargement, transformation or other improvement interventions, as well as relevant to the final shut-down (closure) and the end-of-life dismantling or reconversion to other use.
Manufacturing and petrochemical plants, power stations, oil&gas rigs, buildings and civil infrastructure, pipelines, mining facilities, iron and steel works are just some of the facilities requiring great efforts in order to make them safe (to workers, to the civil population and to the environment) for further intervention and/or demolition purposes; ships represents a major-risk typology to be considered as well.
The course will mainly focus on the preliminary risk assessment of a site, on the implementation of the measures aimed at reaching a “safe for work” status and on the following demolition/deconstruction techniques; it will provide the basic elements to trace the history of the plant/building/ship and the potential critical issues associated to structural safety, hazardous materials and residual energy potential.
Mothballing procedures, recycling and reuse of recovered materials, legal requirements, decommissioning planning and design for deconstruction (DfD) philosophy will be taken in consideration as well. Prerequisites
- Basic knowledge of chemistry, physics, thermodynamics, technical drawing; a good comprehension of the English language is recommended to fully understand the suggested reference texts and the media supports that will be presented during the lessons.
