Objectives

The course provides the knowledge of risk analysis applied specifically in power industry, starting with advantages and effectiveness of its application. It presents the regulatory basis and requirements, and elaborate commonly used methods through number of examples.

In the end of the course students will be able to

  • understand procedure for risk-based inspection and maintenance as defined for European industry by CEN CWA 15740:2008
  • present damage mechanisms specific for power industry
  • quote inspection techniques as used in power industry and their effectiveness
  • understand principles and conditions for life and risk assessment 
  • understand importance of quality assurance program in mitigation or reduction of risks in power industry
