| Abstract | The results of a systematic approach to several extraordinary turbine maintenance outages that were executed over one year by ProGen as the service provider will be discussed. All of these outages were conducted successfully within the time and budget parameters set. There were no commissioning or operational issues encountered upon return to service. All of the outages were planned to a tight schedule based on optimizing historical performances. Although emergent work was discovered during most of the projects, the work was able to be managed within the allowed time frame and within the planned budget. The paper will discuss the challenges faced and successes achieved with the execution of these outages. It will focus on the principles followed to ensure the outcomes achieved. The principles discussed will be: 1. Partnership relationship between the supplier and the owner/operator 2. Planning for the outage using historic and forecasted findings 3. Plant life cycle managing and forecast 4. Preparation for execution done to the correct level 5. Decision making during the complete process leading up to the outage 6. Execution of the outage 7. Technical communication and decision making during the outage 8. Reporting on the completed outage 9. Post outage actions and planning for future outages |
