Improving the Efficiency of Wind Turbine Inspections

  1. 1. RVI | Liam Giles Hanna Gothenburg, 15 June 2018 Improving the Efficiency of Wind Turbine Inspections
  2. 2. Agenda 1 Introduction 2 Improving Turbine Lifetime with Gearbox Inspections 3 Challenges of Gearbox Inspections 4 Addressing these Challenges 5 Saving Time and Becoming More Efficient when Inspecting Wind Turbine Gearboxes 6 Close
  3. 3. § By visually inspecting an item, it is easy to understand the whole situation, and a complex idea can be conveyed with just a single still image § RVI makes it possible to absorb large amounts of data quickly Remote Visual Inspection (RVI)
  4. 4. RVI is a visual inspection, and visual defects can be measured For sub-surface/internal defects, other Olympus products may be used, including NDT and ANI Benefits of RVI 1. Easy to understand what is happening inside a component 2. On-site inspection is possible 3. No need to use a special wave 4. No need for a special license
  5. 5. 50% of us can identify this 50% of us can identify this Probably only 10% can gain anything from this RVI Compared to Other Techniques
  6. 6. RVI Compared to Other Techniques We can all draw a conclusion from this

  8. 8. Commercial wind turbines can be operational for over 20 years Frequent reasons for wind turbine damage include: • Corrosion • Moisture • Lightning strike • Material loss in the machinery Continuous monitoring systems are installed to detect early warning signs of damage Improving Turbine Lifetime with Gearbox Inspections
  9. 9. Common Inspection Points Inside a wind turbine nacelle High/mid/low and planetary stage gears and bearings High/Mid/Low speed gear Planetary gear § To address these early warning signs and as a routine precaution, wind turbine gearboxes are regularly inspected to avoid repairs and downtime and to ensure a long lifespan

  13. 13. Lightweight and ergonomic design Addressing the Challenges: IPLEX® G Lite Videoscope § 1.15 kg (2.5 lb) § Compact body fits in your palm with a hand strap § Carrying case easily fits in most airplane overhead bins Case size: W 455 H 330 D 175 mm W 18 H 13 D 7 inches
  14. 14. Rugged Addressing the Challenges § IP65 rain and dust resistant § Tested to U.S Department of Defense standards (MIL-STD-810G and 461G) MIL STD Type MIL 810G 1.2 m (4 ft) drop test Vibration Blowing rain Humidity Salt fog Sand and dust Icing/freezing rain Explosive atmosphere MIL 461G Electromagnetic interference (EMI)
  15. 15. Improved brightness Addressing the Challenges § A powerful LED in the main body provides 2x the brightness of its predecessor (IPLEX UltraLite) § The PulsarPic™ processor and WiDER® technology continuously optimizes image brightness 0 100 200 300 φ 6mm φ 4mm UltraLite G Lite (mm) Brightness Distance Comparison All scopes tested are 3.5 m length models.
  16. 16. Image comparison—wind turbine gearbox bearing Addressing the Challenges IPLEX® G Lite IPLEX UltraLite

  18. 18. Clearer images during oily inspections Inspection Efficiency Conventional model Oil clearing design Oil remains on the lens New design remove oil using grooves § New design remove oil from the surface of the distal end § Spend less time cleaning, more time inspecting
  19. 19. Inspection Efficiency TrueFeel® electric articulation § The IPLEX G Lite videoscope’s ergonomic design is complemented by TrueFeel articulation, making the joystick incredibly responsible § A light touch produces an immediate response and precise movement from the insertion tube so that it is easier to maneuver the scope
  20. 20. Inspection Efficiency Live image streaming § Wirelessly send live inspection images to smartphones and tablets. § Secure streaming with the connection channel and password Wireless USB adaptor Dedicated iOS app: RVI Image Share
  21. 21. Inspection Efficiency Constant video recording § The IPLEX G Lite videoscope automatically records the last 30 minutes of your inspection, even between startups and battery changes § This function repeats “capture new” and “delete old,” so the recording media does not become empty.
  22. 22. Inspection Efficiency Video recording index function § During movie recording, it’s simple to add an index so that an inspector can find the bookmarked location quickly Still image capture function § With the push of a button, take a still image while recording a video § By adding index marks, you can skip backward and forward to the marked positions when playing back or pausing the movie
  23. 23. Inspection Efficiency InHelp™ inspection assist software helps you: 1. Streamline your inspection with a customizable workflow 2. Manage all the inspection media in one location 3. Quickly generate inspection reports with customizable templates
