Blade Repair Standard / V4 2023-05-02
Emphasise the importance of consulting blade manufacturer documentation to obtain the manufacturer specific damage categories for the accurate reporting of blade damage Demonstrate the ability to recognise typical defects and failures found in wind turbine blades, and correctly identify which damage category each failure or defect falls under
The participants shall:
Share their own understandings about how to recognise typical defects and failures found in wind turbine blades and which damage category each failure or defect falls under
ELEMENT 21.2 - REACTIONS TO DAMAGE CATEGORIES
Learning objectives:
183) The participants can recognise the importance of consulting blade manufacturer specific documentation (Knowledge, basic level)
184) The participants can describe typical reactions to the different damage categories (Knowledge, basic level)
The instructor shall:
Highlight the importance of consulting blade manufacturer-specific documentation. This is for guidance on how to react to the various categories of blade damage and to highlight that damage categorisations can vary between companies, so participants should always adhere to company-specific damage categorisations
Outline the following typical reactions to damage categories:
a.
no action required - turbine can run
b.
follow-up inspection required - turbine can run
c.
repair required within a time frame - turbine can run
d. repair required within a short time frame - turbine can run
e.
repair required immediately - stop the turbine
Describe the lost production implications of stopping a turbine
Ask the participants relevant questions about the typical reactions to the different damage categories, and to recall where manufacturer-specific information about reactions to blade damage can be found
