WindEurope is almost here
Brüel & Kjær Vibro will be attending WindEurope in Bilbao, Spain on April 5-7 for their annual event. Our very own Sr. Application Engineer Michael Hastings will be one of the poster presenters. Mike will cover topics such as, “Virtual site survey for wind turbine monitoring” and “Loose bearing detection in wind turbine gearbox.”
Who is Michael Hastings?
Mike has been with Brüel and Kjær Vibro for the past 32 years. Here he has worked with developing various machine monitoring strategies and optimization techniques. He is currently working with strategic marketing development, analysis, and communications. Mike has written numerous articles, papers, and webinars on machine condition monitoring, especially in the LNG industry. He is also the convener for an ISO workgroup for creating standards for condition monitoring and diagnostics of machines.
Virtual Site Survey
When the Covid-19 pandemic started it forced us to change how we conducted site surveys. Before the pandemic, a monitoring system specialist would spend a couple of hours in the nacelle to determine where the sensors needed to go. Placement of the sensors is important as it can have a significant effect on the signal quality delivered to the data acquisition and processing unit. A monitoring specialist’s expertise is crucial to making these placement decisions. Not being able to have a specialist conduct a site survey is very problematic. Therefore, We decided to let the owner/operator technicians and service providers conduct the actual survey. However, they would conduct the survey under the virtual guidance of a B&K Vibro specialist. This solution has allowed us to operate as usual.

Loose Bearing Detection
Outer and Inner bearing looseness is a problem that if not corrected then problems will compound. If the outer race is loose then it will rub against the gearbox casing bore, enlarging it. If the excessive clearance is not corrected in time then the parallel stage shafts can become misaligned causing tooth damage and damage to the other bearings. A fractured tooth can fall between two meshing gears, and the gearbox casing can crack. Inner race looseness can wear out the surface of the gear shaft where the bearing is mounted. If the shaft is damaged then the entire gearbox needs replacing.

See you there!
We can’t wait to fly out to Bilbao for Wind Europe. April 5 cannot come fast enough. We know Michael Hastings is itching to give his poster presentations about “Virtual Site Survey” and “Loose Bearing Detection”. In the meantime, be sure to review the articles and video mentioned above.
