Abstract

This paper deals with the development of a semi-quantitative Risk Based Inspection programmes for the Eskom fossil fired generating fleet. This study comes as a result of internal and external factors that affect Eskom from producing electricity in a safe, sustainable manner to ensure security of electricity supply. Eskom has embarked on a risk based maintenance approach to meet the statutory and safety requirements as stipulated by the Depart of Labour as well as to potentially reduce outage costs. The European CWA15740 approach was used to develop the Risk Based Management System.
