Benefits of Factory Service vs Field Repair• No weather factor. When conditions are not conducive to proper curing and/or work-at-height becomes hazardous, factory repairs provide an efficient and cost-effective solution.• Refurbished blades (with documentation) can be delivered ready to install on-site or maintained in the factory laydown yard until needed.• Damage that is too extensive or complicated for field service crews is often possible with the support of technical resources at the factory.• For warranty repairs, serial defects can be addressed with engineered solutions in a controlled environment.• Performance upgrades such as vortex generators, winglets, and blade tip extensions can be engineered and added in the factory. These performance-enhancing measures often help justify the cost of transportation and repair and can offer an attractive ROI.

Provisioned through MFG’s three blade manufacturing facilities, all work is done in a clean, controlled environment with a constant ambient temperature ensuring that all resins and materials cure properly. Engineering and Quality professionals who are proficient in OEM standards are available to assess and guide the repair work.

A N A L T E R N A T I V E T O F I E L D R E P A I ROperators are discovering that when up-tower repairs are not viable—due to safety, weather or extent of damage—factory repair and restoration can deliver added service life to blades.

Automated Wind Blade Scanning Improves QA AUT inspection is a repeatable technique providing a detailed image that can be analyzed to insure specification compliance. This method provides an accurate, storable record of defect sizing and placement data for repair work, root cause determination and defect elimination. • According to Mark Rumrey at MFG South Dakota, “In addition to giving us better data, AUT is less labor-intensive and faster. One operator can complete a scan with occasional extra support—versus the manual 2-person system.” Mark is a certified level III non-destructive technician and played an instrumental role in maintaining MFG Wind’s market leadership for quality testing.

MFG Wind blades are now being inspected with the latest automated ultrasonic technology (AUT). The company is an early adopter of ultrasonic testing, and currently the only manufacturer using an automated ultrasonic scanning system to inspect 100% of all bond lines on new blades.

In wind turbine country, spring is the season opener for fleet maintenance and performance optimization projects. Annual mechanical and visual inspections

are where this process begins, and there are some intriguing new options for owner/operators to gather important information for scheduling seasonal work.

With the recent approval of UAV’s (drones) for industrial use, MFG Energy Services is one of the first wind O&M service companies to offer aerial inspections. This technology allows the customer a new alternative to down-tower, rope access and platform inspections that can be faster, more comprehensive, and more economical in many cases.

Inspection Services• Aerial Inspection—drone equipped with HD camera (video, photo or infrared). It is now possible to get complete root-to-tip imagery of blades, including leading/trailing edges and high/ low pressure shell areas. Each section is inspected for surface imperfections, bonding cracks, delamination, pitting and other potentially serious defects.• Up-tower Inspections via a platform or crane basket• Down-tower HD Photography—using high power telescopic lens and high resolution digital camera• Tap Test—Non-destructive audible test to identify composite degradation• Blade Internal—Composite surface and LPS (Lightning Protection System) inspection

Reports Formatted to Meet Your Needs• Comprehensive inspection documents • Determination of warranty/ non-warranty liability• Repair recommendation with labor/cost estimate provided

Each inspection technology is suited for the different blade model, site-specific environment and various customer requirements. We are here to help you navigate through the technology options to find the best fit for your needs.
