Allen Hall: ONYX Insight's ecoPITCH monitoring system has become crucial for wind farm operators facing blade root insert failures. These failures start invisibly but can end catastrophically with blades detaching completely. This week we speak with Forrest French Senior Project Engineer, and Martin McLarnon, sales Director for North America at ONYX Insight.
Their ecoPITCH system detects dangerous movements before visible signs appear as Forest notes in the interview. By the time you can get a feeler gauge measurement, it's probably too late. So join us to discover how data-driven monitoring is helping operators make smarter maintenance decisions preventing million dollar disasters and keeping turbines spinning safely.
Welcome to Uptime Spotlight, shining Light on Wind. Energy's brightest innovators. This is the progress powering tomorrow.
Allen Hall: Martin and Forest. Welcome to the [00:01:00] show. Hello. How's it going? Thanks for letting us. Yeah, we're really interested to, to talk to you today just because there's so many blade root issues from pitch bearings and blade bushings or inserts as they're called sometimes, and a number of other issues. And when we talk to operators, what they tell us is, oh, we, you use ecoPITCH.
And they love that system. But I want to, I wanna back up first and talk about what are some of the operators experiencing out there in the field And ecoPITCH system was originally developed to look at pitch bearing problems and forests. What are some of those pitch bearing problems you're seeing out in the field today?
Forrest French: Yeah, so it, it, it's a funny story. It was originally developed for pitch bearing, uh, applications. Um, the industry as a whole started experiencing this root insert issue, so we were able to, we were kind of in a perfect position, right? It was, it was a, it was a [00:02:00] really serendipitous thing that we, we had just developed this product and we could easily pivot.
To measure both the pitch bearing and this root insert issue. Uh, the, the pitch bearing issues are admittedly the, the more difficult, uh, issue, right? To measure. Um, there's, there's some, some great opportunities for value and there's also some really good challenges to come along with that. Um, pitch bearings, uh, they, they don't rotate quickly.
Right. Uh, when, when we talk about typical CMS typical vibration monitoring, you're looking at a very, very fast rotating, uh, shaft or bearing, et cetera, and you're able to pick up on those frequencies as they revolve. You don't get that with a pitch bearing. It's a very slow moving, uh, slewing bearing. Um, so picking up.
Noise through vibration can be very difficult, uh, because again, you don't get that frequency of that [00:03:00] rotation, so you're left with nothing but uh, a bunch of noise. Right. And you're hoping that that noise floor is low enough that you might capture a bit of crunching of cage material or anything like that?
Right. The alternative in what, in what we use ecoPITCH for is it's very simple. We, we point a an inductive displacement sensor right at the pitch bearing itself. Typically the inner ring, depending on the type of turbine. And what we're looking for is any kind of slop or displace...
