Hydropower utilities often detect damage or manufacturing defects on hydropower equipment during inspections and overhauls. Damage mechanisms acting in those components can severely limit the component life and plant integrity, leading to unplanned outages and costly repairs. Fitness-for-Service (FFS) assessments are an alternative to the early repair or replacement of damaged hydropower equipment, which has been used by utilities world-wide.
FFS assessments are multi-disciplinary quantitative engineering analyses to determine whether damaged or defective equipment is suitable for continued operation. The assessment is done by conducting more detailed analyses than typically considered in the original design, and may even include a realistic representation of the damage observed. The outcome of a FFS assessment is a decision to run the component as-is, alter it, repair it or replace it. The use of FFS assessments can provide significant cost savings, for example if a turbine component can be shown to be fit-for-service without repair or replacement.
This workshop provides an introduction into FFS assessments and how these can be used within the Hydropower industry to better define asset integrity and manage asset remaining life.
Key learning objectives include:
• Presenting typical damage mechanisms, how to identify them and how they occur for both rotating and stationary equipment.
• Review the sections of ASME FFS-1 used for assessing flaws/damage.
• Solve an example problem on the practical application of the techniques incorporated in ASME FFS-1.
• Overview of remaining life assessment, remediation and methods to extend the life of damaged equipment.
• The relationship between ASME FFS-1 and other FFS standards and how to interpret FFS outcomes.
This workshop will provide interactive examples and discussions about these topics to provide an educational platform, as well as provide an opportunity for attendees to engage with the broader industry around their own issues and lessons learnt.
This workshop is suitable for all experience levels and backgrounds from asset/maintenance engineers to operators and plant managers alike. The workshop is designed to provide a basic understanding of the FFS process to enable informed conversations and provide the knowledge and tools to approach asset integrity problems.
The workshop will be facilitated by Quest Integrity who have over 20 years experience in the application of FFS assessments within the Hydropower industry. Quest Integrity workshop faculty will include:
• Eric Scheibler – 18 years experience within asset integrity
• Vitor Lopes Garcia – 15 years experience within asset integrity
• Samuel Stephens – 5 years experience within asset integrity
