Allen Hall: In the wind industry, a turbine standing still often means one thing, waiting for parts that should be readily available. This week on the uptime spotlight, we’re joined by Lars Benson of AC 8 83, which is based in Canada. AC883 has direct connections to manufacturers in Denmark where most critical worm turbine components are actually produced Lars shares, house site operators can cut costs and dramatically reduce downtime by bypassing the OEM middleman and sourcing parts directly from the original suppliers.
Welcome to Uptime Spotlight, shining Light on wind Energy’s brightest innovators. This is the progress powering tomorrow.
Allen Hall: Lars, welcome back to the show. Thank you. Spare Parts is a huge issue all over the world, but it seems like in the US and Canada, there’s always a shortage. They’re looking for spare parts. They don’t know where to get them, and the easy answer has been to call the original equipment manufacturer in terms of the GE Vestus Siemens, cesa, Nordex, whoever that may be, and just to place a order.
There are other opportunities out there. What happens when a wind side in Texas just decides to buy from the wind turbine manufacturer? How much are they paying overpaying for that part?
Lars Bendsen: I can’t say exactly on on dollars and cents, but but we know the markup from the OEMs.
Then they’re not shy of earning money on that, those parts. And yeah, so it’s very simple. We can get those parts directly from Europe directly from the suppliers to the OEMs.
Allen Hall: Yeah. And if I’m an operator, and I haven’t been over to Denmark to look at the situation there, a significant number of critical parts are actually manufactured in Denmark or in the surrounding areas.
You have no way of knowing that if you own the turbine,
Lars Bendsen: that’s true. You don’t. Somehow the OEMs have been really good and keeping a bit of cloud cloudy around that area. It’s actually pretty simple. They all produced either in in Denmark and Germany for basically all turbines. GE turbines is a target turbine from Germany that that they bought back when.
So that’s why sim that’s a German turbine as well. It’s not a US turbine at all.
Allen Hall: And the supply chain has remained that way for a long time.
Lars Bendsen: It’s a BP parts. It’s standard parts. There’s no rocket sites in it. Of course, there’s some legacy some software parts and stuff that we could be desk, some, what we call it electronic boards, which software on, of course we can’t do that.
That’s fair enough, right? That’s actually where the OOM has its value. That’s totally good.
Joel Saxum: I think part of the reason that you see this, that gap there in the industry is the simple fact that, and I don’t take this as a slight Lars because I love your website and what you guys do for marketing and branding, but in that corner of the world, and Alan, you and I were just talking about this couple of German companies we’re talking about they’re not that good at global branding and global marketing.
As a unit like culturally, so you don’t see really what’s going on almost behind that curtain as an American, when you log in and go I need some breaks, or I need this, or whatever. You don’t see that manufacturer’s website pop up. You may see an AC 8 83 pop up that says, Hey we have we sales spare parts.
But you just don’t as an American and to be honest with you. Running around the United States talking to all these wind site operators, they’re so dang busy with their day-to-day life and solving the, putting out the fires and the problems that they have every day, that they don’t have time to go search for that stuff.
So what do they do? They just call their procurement or the person that they know and they say, Hey, get me this. And if they end up overpaying for. 10, 20, 50% or whatever. It got the turbine back up and runway because uptime is king. So what else are you guys doing to strategically work with your clients and your customers to make sure that they don’t have to do that?
Lars Bendsen: Generally speaking, I agree with larger countries let it be germinated. But the US and Big Canada they have such a big inner market. They’re horrible in doing export, generally speaking. They’re not good at it. They’re really good at producing stuff and doing the take care of their own stuff.
Denmark, I think it’s 97% is export or being produced in Denmark, something like that. Because we have five, 5 million people, there’s no inner market we need to get out there where the market, inner market in US and Canada and Germany is so big. You don’t, we don’t need export. We’re not real good at it.
And don’t call Canada US export. It’s not export, it’s the in the market. So far,
Allen Hall: the turnaround times from the OEMs tends to be slow if they have the part in stock and there’s so much demand at for some specific parts that they don’t always don’t have it sitting on a shelf to send to you, which is a huge problem.
So you have to develop a subsequent chain, a supply chain, and why not go right to the source? Which is gonna be in Denmark for the most part. Why not do that as to source the actual part instead of an imitation part or a refurbished part, which I’ve seen more of recently. You can actually get the real part.
Lars Bendsen: It’s still surprising me sometimes. We hadn’t known em last year. They just closed their warehouse for three months. We just closing them. We cannot supply it for three months. How’s that gonna work? This wasn’t a European summer thing, was it? No, that was gonna be six weeks. That’s only six weeks. No, it was exactly in the fall, I think it was.
And they just decided to close it for three months. And I don’t understand this, OEMs should earn $0 on the turbines itself. They’re earning money on the service and the parts look at the accounting on vest and seems real. They’re earning no money. It’s only on their aftermarket and vest, in all fairness, are extremely good at it.
Really good at it. They have 75% or whatever the accurate number is covered of the fleet with service and parts is great. So we are not hunting as much vessel because why would we find that needle in the haystack where you could say that Siemens and ge they have less percentage, way less, maybe half of that depending on countries, et cetera and areas.
But still, again, how can you allow yourself to just close your warehouse to three months?
Joel Saxum: That’s crazy. Do let me ask you something about that, Vesta the vests setup ’cause in my mind, okay. I worked with a Danish company, very process driven, very controlled. There was step changes in gates and, everything was mapped out very well in how the company operated.
So do you believe that the, one of the reasons that Vestas may have a really good control of spare parts inventory and the direct connection to those sites is because they sign those. 20, 25, even 30 year FSAs. Is it all based on this overarching business model that, that encompasses that and the others aren’t just, aren’t doing that?
Lars Bendsen: I don’t know. I think it’s I think everybody wants to do it. That’s just my 2 cents. I’m not an expert in that area, but my 2 cents is that vessel has the power to demand that. And they’re not selling any new wind farm without a service contract, whatever’s 5, 10, 15. They do not. Where some of the wind inside the smaller, they have less power.
The owners say, you know what, that’s all well and good, but then we’re not gonna buy your turbines. And then GE and Siemens has to cave in a little bit. That’s my 2 cents.
Joel Saxum: I think strategically like GE with having expanded in their service thing and then now changing it to the hub and spoke model, like I think that this is my 2 cents, right?
I think GE saw some bloat. In what was happening in service. And I’m not gonna say parts ’cause I don’t think that’s true, but service and this FSA and I think that GE is actually strategically pulling back from signing these FSAs. And because some of the stuff with, we’ve heard horror stories with, and this isn’t just ge, it’s all the OEMs with, liquidated damages, catching up with people and those kind of things because they don’t have access to spare parts.
So they don’t have access, they don’t have the service people to get out there quick enough. So it’s a, there’s a large problem in the industry and I would say that if you’re a wind farm operator or wind site supervisor, technician, whatever, it’s at some point in time, you’ve felt the pain of not having that spare part that you need to get your turbine up and running.
And that’s where a C 83 comes into play.
Lars Bendsen: Yeah, I agree, but I also believe that some some owners are too small that the OEMs even care. We have seen some horrible example that, you know. Care list. That sales person sold that wind farm. That’s it. He can care list and the aftermarket people sitting in Denmark and they are, they’re closing at four o’clock eastern as it’s four o’clock.
It’s not four 10. It’s four o’clock.
Joel Saxum: So if you’re in the central part of the United States, you need to be on the phone by 7:30 AM Otherwise you’re not getting your stuff.
Lars Bendsen: No. Or on Fridays is close by noon, so forget about it. You get an answering machine, so you can’t even call on Fridays.
So that happens. We have a policy, we pick, we always pick up the phone, we all always answer our emails. We don’t have an out on office, not on purpose. At least doesn’t exist so I think it’s more avail, be available and go the extra mile instead of just sitting for a number. There are might be two picture lenders.
Let’s take an assemble of that. There’s four different vendors, which the same A nine B number from Siemens. There are four different A nine B sorry, producer of a nine BXX, x. So you can pick the most expensive one. You can pick the cheapest one, pick whatever you want. And there’s probably a reason between something, a correlation between quality and price often this.
So yeah. It’s about knowing those manufacturers and have access to them. Yeah. And we are, I think we’re pretty good at it.
Joel Saxum: Yeah. As I’m gonna put my wind farm operator hat on for me that, that’s that triangle. Good. Fast and cheap. Pick two. I. That’s what I always look at.
Two outta three. Yeah. But having someone in the corner, like AC 80, 83 that knows, hey hey Lars, I need this part. Great. Okay. I can get it from one of these four people. Here’s the cost for all four of ’em. Here’s the quality of our opinion and the track record we’ve seen, and here’s the lead time.
’cause that’s always the big one. If it’s a reactive situation where I need a part now, which we hope we’re not doing as much reactive as proactive, but if it’s a reactive part and I need it now, I need to get that turbine back up and running. You guys have the answers to those questions.
Lars Bendsen: Yeah, I think I agree with you that’s the reactive part of it and that happens.
SC actually happens a lot and I think we are back to what you said around before, that everybody is so lean, that site manager don’t have that extra person to source those parts. And all of a sudden we have a turbine down, we are missing one animal meal for $500. How can that happen? And of course you could be unlucky as well.
I totally get that part. We are trying to be more proactive. So if we have a major owner that have 20 or 30 sites, because you see they use the same parts, all of them. So one, don’t, we bundle out procurement instead of taking one off all the time. We spending a ton of time with one off $500. Procurement and it takes too much time and it’s too expensive for everybody involved.
There are some suppliers now I got actually hit by it. Some suppliers in in Denmark now they have a minimum or a quantity, or you get a fee, extra fee on it. So you can order a one animal meter used as an example without, is a 250 or $300 fee on it for handling the order. We’ve seen that as well.
Joel Saxum: So reactive is a lot of where the market sits, but how are you guys working with customers to be more proactive in their strategies for spare parts?
Lars Bendsen: As in the back office say GaN, Sydney, et cetera, they’re extremely data driven. We can see the history of what had been quoted, what had been ordered, what pricing has been ordered, when was it, et cetera.
So we know the history. I said, why? We can see we are buying 40. Why do you buy one or two design? And even if that person cannot do it, we’re still gonna buy five or 10. So we have something that helps our what call it procurement power. We leave it un stock because we are trying to avoid, has too much in stock and we do not wanna have obsolete parts either.
So that’s the kind of the balance we have, we are finding.
Allen Hall: Lars, can you gimme a sense of what kind of parts you can acquire or from the original equipment manufacturer? In Denmark,
Lars Bendsen: we just set up a big agreement with one of the main the major filter suppliers. Now we have a nine p numbers for all fillers in the world and for western fillers where we have all fillers and it’s a fraction of the price we’re paying today.
Fraction, pit cylinders motors, gears, et cetera. We are staying away from major components. We’re staying away from from gear boxes, generators, habit supply, main shaft and bearings for simul because that’s the focal point. So that’s, we could do that. But gearbox, generators it’s not worthwhile for us to do it.
We don’t add any value. You could get that part. It’s just a part number. We can’t add any value at all. So decided of staying away from it. We don’t wanna take the risk for a small portion of dollars.
Allen Hall: And if I’m sitting at a wind site and I’m getting requests for a specific part, how does that process work?
So I’m calling Sydney at your site or go, or getting ahold of you on LinkedIn. Then how does that work? How does that procurement system work? How do you navigate that? Because it sounds like you have some of the parts sitting on the shelf. Some you have to go acquire and negotiate.
What’s that process look like?
Lars Bendsen: The process is that you’ll get an email we got your R fq, we’re working on it right now. You’ll get an email within an hour that we have. It don’t, we won’t leave you high and dry. We are responding and then we are gonna source it right off the bat. If you don’t have it, and within a day or two you will have an answer back with a, with the price and lead time.
Allen Hall: Okay. So that’s a really short response time because usually it takes several days to get someone to re return that phone call.
Lars Bendsen: Yeah, so that’s the thing. Availability is key, right? Availability to the parts availability is key and it goes for the parts as well. You said lead time? We get way short on lead time, but call the manufacturers directly.
Waste or,
Allen Hall: and the, obviously the equipment manufacturers must have stock on the shelf. They have to do that so that those parts do exist. We just didn’t know where to find them until we called AC 8 83.
Joel Saxum: That’s a story that you hear a lot in the United States, right? Again, Alan and I travel wood Farm.
Oh, these, there was some German guys here. There was some Danish guys here. It’s always German and Danish. We had to get these special bolts from Germany, or we had this. So now everybody has their own Danish guy that they can call Lars that person Yeah. That has the connections to, to the mainland, to the motherland that can get these things for ’em, because that’s the troubling part.
Like we said, you don’t have time to, procurement is tough. Strategic procurement is difficult. Even people that are doing procurement at a large scale in an organization, say you’re in the back office and you’re the procurement person. They’re dealing with so many things that to find this one part at one of these few manufacturers over in Denmark, that’s difficult.
So now you have every, everybody that’s listening here has the connection to that dane that has the connections over there and can get it done for ’em.
Allen Hall: One of the big criticism in the United States and Canada is that when anybody drives by a wind farm and turbines not operating.
It’s just, it’s a knock on the industry. And the most times that is occurring is because they’re waiting for a spare part, honestly. Real simple stuff. Filters, for example, is a good one, right? And parts that they can’t get the hold of, but they just don’t know how to acquire them. And now they’ll listen to the podcast.
This is the way to do it. You call ours, you call Sydney at AC eight eighty three and you get this process started and then at that same moment I know Sydney is really sharp. She’s gonna provide you the list of things you can get. So she, you tell her, Hey, I got a GE two X machine. She says here’s the list of parts we can get for you.
Wow. That just saved my life for most procurement people. And that’s a personal, Sidney is not your friend for life because she is saving you. A lot of money and a lot of time, and a lot of hassle, which is the point, right? This is why everybody goes to AC 83 because it’s simple, easy to get things done.
Lars, how does an operator a site supervisor, a procurement person, get a hold of you to start ordering some of their spare parts through AC883?
Lars Bendsen: You have a website, ac883.com or my email, lars@ac883.com
Allen Hall: And you can also reach Lars and AC 8 8 3 at contact at ac883.com. The website’s great, so get ahold of Lars, get ahold of Sydney, get your projects moving.
Again, Lars, thank you so much for being back on the program. We love having you. Thank you. Thanks.

Welcome to Uptime Spotlight, shining light on wind. Energy’s brightest innovators. This is the Progress Powering tomorrow.
Pete Andrews: Pete, welcome to the program. Good to be back. Yeah. See you face to face. Yeah. Yes. This is wonderful. It’s a really great event to catch it with loads of the. UK innovation that are happening in the supply chain. So it’s, yeah, really nice to be here.
Allen Hall: This is really good to meet in person because we have seen a lot of bolt issues in the us, Canada, Australia, yeah.
Uh, all around the world and every time bolt problems come up, I say, have you called Pete Andrews and Echo Bolt and gotten the kit to detect bolt issues? And then who’s Pete? Give me Pete’s phone number. Okay, sure. Uh, but now that we’re here in person, a lot has changed since we first talked to you probably two years ago.[00:01:00]
You’re a bootstrap company based in the UK that has global presence, and I, I think it’s a good start to explain what the technology is and why Echo Bolt matters so much in today’s world.
Pete Andrews: Yeah, absolutely. So, um, as you said, we’re a uk, um, SME, there’s a team of 13 of us based here in the uk. Yeah. But we do deliver our services internationally, but really focused on Northern Europe.
Yeah. But increasingly we’ve done more in the US and North America, a little bit in Canada. Um, but our big offering really is to help wind turbine operators and owners reduce the need to routinely retire in bulks. So we have a quick and simple inspection technology that people can deploy, find out the status of their bolt connections, and then.
Reti them if necessary, but the vast majority of the time we find that they’re static and absolutely fine and can be left [00:02:00] alone. So it’s a real big efficiency boost for wind operators.
Joel Saxum: Well, you’re doing things by prescription now, right? Instead of just blanket cover, we’re gonna do all of this. It’s like, let’s work on the ones that actually need to be worked on.
Let’s do the, the work that we actually need to, and instead of lugging, like we’re looking at the kit right here, and I can, you can hold the case in one hand, let alone the tools in a couple of fingers. As opposed to torque tensioning tools that are this big, they weigh a hundred kilos, and those come with all of their own problems.
So I know that you guys said you’re, you’re focused here. You do a lot of work, um, in the offshore wind world as well. Yeah. I mean, offshore wind is where you add a zero right? To zeros. Yeah. Everything else is that much more complicated. It costs that much more. It’s you’re transitioning people offshore to the transition pieces.
Like there’s so much more HSE risk, dollar risk, all of these different spend things. So. The Echo Bolt systems, these different tools that you have being developed and utilized here first make absolute sense, but now you guys are starting to go to onshore as well.
Pete Andrews: Yeah, that’s right. So I mean, as as you said, that there’s really [00:03:00] three main benefit areas we focus on.
The first one is the health and safety of technicians, right? As you said, some of the fasteners used offshore now are up to MA hundred. So a hundred millimeter diameter bolts,
Joel Saxum: four inches for our American friends. Yeah, absolutely.
Pete Andrews: And they probably weigh. 30 kilos plus per bolt. Yeah. Um, so just the physical manual handling of that sort of equipment and the tightening equipment for those bolts is a huge risk for people.
If you think 150 bolts lifting or maneuvering, the tooling around on on its own can cause all the problems. So as well as the inherent risk of the hydraulic kit failing. So occasionally we see catastrophic tool failure. Is, which have really high potential severity, you know, sort of tensioner heads ejecting or crush injuries from Tor.
So that is really a key focus for our customers, just to [00:04:00] keep their teams safe, but also you have to be the cost effective and the the major cost benefit we allow is that we don’t have to revisit every bolt and every turbine like you’d have to do if you were retyping. So we believe there’s something of the order of a million pounds per installed gigawatt saving.
By moving from a routine REIT uh, maintenance strategy to a focused condition based inspection, you significantly reduce the amount of intervention you make and keep your turbines running more and reduce the boots on the ground on the turbine. So three real kind of, um, key. Benefits for people adopting our technology
Allen Hall: because we routinely see tower bolts being reworked or retention depending on who the manufacturer is.
And I’m watching this go on. I’m like, why are [00:05:00] we doing this? It seems, or the 10% rule, we’re tighten 10% this year, and they’ll come back and see how it’s going. That’s a little insane, right, because you’re just kind of. Tensioning bolts up to see if one of them has a problem and then you just do more of them and we’re wasting so much time because echo bolts figured this out years ago.
You don’t need to do that. You can tell what the tension is in a bolt ultrasonically, which was the original technology, the first gen I’ll call it, uh, that you could tell the length of the bolt. If the length of the bolt is correct within certain parameters, you know that it is tension properly. If it’s shrunk, that probably means it’s not tensioned properly.
That’s a huge advantage because you can’t physically see it. And I know I’ve seen technicians go, oh, I could take a hammer and I can tell you which ones are not tensioned properly wrong. Wrong. And I think that’s where equitable comes in because you’re actually applying a a lot of science simply [00:06:00] to a complex problem because the numbers are so big.
Pete Andrews: Yeah, I mean that, that, that’s been the real. Driving force between our offering is to simplify it. So ultimately we’re based on a non-destructive testing technique. It’s an ultrasonic thickness checking technique, but when from the non-destructive testing background, it’s crack detection, people have time, they can be, it’s a very precision measurement.
People have to be trained in the wind industry. We’re trying to inspect. A thousand, 2000 bolts a day at scale. It’s a completely different, um, ask of the technology and the way the technology has been developed historically has required too much technician expertise, too much configuration and set up time, and hasn’t delivered on the, on the speed that’s needed to be efficient in wind.
And that’s where our bolt wave [00:07:00] unit we’ve, that we’ve developed over the last. 18 months, let’s say, where all of our focus has gone to make it as slick and as easy for a client technician to pick up with minimal training. It’s through an iOS interface. Everyone understands it intuitively. Um, it’s a bit like using the camera app on your phone.
You know, you’re just hitting measure, measure, measure, measure, measure 10 seconds a bolt as you move the, um, ultrasonic transducer across, and then the data gets moved. Automatically to the cloud, to our bolt platform. And customers can view it in near real time. The engineer in the office can see the inspections happened.
They can see if there are any anomalous bolts, and then there can be communication there and then whether an intervention is necessary. So it’s sort of really changed the way our customers think about managing their, um. They’re bolted joints.
Joel Saxum: Well, I think these are, these are the kind of innovations that we love to see, right?
Because [00:08:00] we regularly talk about a shortage of technicians, and this isn’t, I was just learning this this week too, like this is not a wind problem. This is a everywhere problem. No matter what industry you’re in. Use are short of technicians. But we’re seeing like a tool like this is developed to be able to scale that workforce as well.
Right. You don’t need to be an NDT level three expert to go and do these things. ’cause there’s a very few of those people out there. Right? Right. We know the NDT people, a lot of NDT people, and that’s a hard skillset to come by. Yeah. This can be put in the hands of any technician. Yeah, a quick training course.
Just, Hey, this is how you use your iPhone. You can check Instagram, right? Yeah. Okay. You can off figure. Yeah, have fun. See you at lunch. Um, but they can, they can make this happen, right? They can go do these inspections and you’re getting that, that, uh, data collected in the field. Centralized back to an SME that’s looking at it and you don’t have to put that SME in the field and try to scale their ability to go and travel and do all these things.
They can be in the office making sure that the, the QA, QC is done correctly. I love it. I think that that’s the way we need to go with a lot of things. [00:09:00]Uh, and you’re making it happen.
Pete Andrews: Yeah. And it’s a real kind of. F change in mindset for us. So originally when we started Ebot, we were using third party hardware.
Yeah. Which required a bit of that specialism. Yeah. A bit of care about the setup of the project, getting multiple parameters configured before you got going. And it wasn’t really something we could put in the hands of a customer.
Joel Saxum: Yeah.
Pete Andrews: Which meant Ebot scale was limited to what our own team could go and do, and regionally as well.
You know, so we’re UK based. Probably 60% of our customers are uk, but now we have this Northern Europe offshore wind is obviously on our doorstep, but then increasingly we’ve done more and more in North America, so we’ve probably been to five or six sites now in North America and expect that to be a growth market because we can, we can now ship the devices over there, give some virtual training help.
Uh, [00:10:00] people set themselves up and then that opens up that market, you know, so it’s been a real change in strategy for us, but has allowed us to have far more impact than we otherwise would just try to be a pure service.
Allen Hall: Well, let’s talk about the big problem in the states of a minute, which are the root bushing or inserts that are loose in some blades.
When you lose that pushing, you also lose the tension on the bolt that can be measured. Is that something you’re getting involved with quite a bit now because of just trying to determine how many bolts are affected and, and where we are on the safety scale of can we run this turbine or not? Is that something that EE bolt’s been looking into?
Pete Andrews: Yeah, absolutely. So I, I’d say there’s sort of two halves of what we do. There’s the, there’s the bulk wholesale monitoring of. Typically static connections to eliminate this routine retitling where it’s not needed typically, typically. But then we have these edge cases of certain [00:11:00] connections and certain platforms that have known bolt integrity problems, and we are working with clients to really, um, manage those integrity risks.
Blade stud is an absolute classic, you know, sort of, I think almost every turbine OEM on some, if not all of their platforms has got. Embedded risk into their blades, pitch bearing connections. Um, so yeah, exactly as you said, our customers are using the technology for two things really. One is to ensure the bolts have been tightened to the preload that was specified or the target window.
And quite often we find there is an opportunity to increase the preload and therefore increase the resistance to fatigue failure. So. You know, particularly on older sites where the bolts perhaps not in the condition they were on day one. Well, they definitely won’t be. Um, when people have gone and retti them, they haven’t got back to where they, they should be.[00:12:00]
So we can prove that and increase a bit of that resilience, but then also start to look for the segments around the joint where, um, the bolt might start loosening or failures are occurring, and find areas where they can really hone in. And actively manage risk. And that sort of leads to what we’ve decided to do for the next year, particularly with Blade Stud in mind, is evolve this technology.
So whilst it’s also measuring the elongation, we will do a defect scan at the same time. So you’ll monitor your blade stu, um, connection and we’re hoping that we can set the device to flag to you there and then. We believe this bulk has got a defect while you’re here, get it changed out before it fails and, and all the knock on problems, um, from there.
Joel Saxum: So what you’re just pointing to there is a, is a workflow, right? So to me that is typical [00:13:00] of some of the amazing, innovative companies in the UK that I’ve run into throughout my career. And that is, you’re a group of SMEs, you know, bolted connections. That’s what you do, right? But then you’re like, hey. If there’s a tool, we could make a tool that would make our lives a bit easier, then it’s like, well, we could make the entire industry’s lives a little bit easier as well.
So let’s iterate on that. And now you’re able to send these kits around the world to look at these things. Hey, you have a problem with this specific model. We can help you with this because we know the failure mode and we know how to look for it. Let’s do that for you. Also here, you’re doing bolt bulk measurements.
We got that for you. But it all kind of flows back to the fact that Echo Bolt is a team. A bolted connection, SMEs that are making tools and being able to also provide consulting if need be. Yeah. Right. Um, to, to an entire industry. And I think that, um, this is my take on it, right? Wind is stop number one. I think you guys are gonna do a fantastic year, but there’s a lot of, uh, opportunity out there in bolted [00:14:00] connections as well.
Allen Hall: A tremendous amount blade bolts being broken from defects in the crystalline structure. What appears to be a more. Rapidly developing issue across fleets that I’ve seen. I went to a farm this summer and the number of blade bolts that were there on the table that were broken on the conference room table was And the whiteboard office.
Yeah. Yeah. This one,
Joel Saxum: this one.
Allen Hall: Your hard head is not gonna protect you from this one. It’s, it’s, it was this, um, I couldn’t imagine the amount of time they were spending hunting these things down. And of course, the only way they were finding ’em was they were broken. You like to catch ’em before they break because it becomes
Joel Saxum: a safety risk.
Just not too long ago we saw an insurance case where there’s an RCA going on and it is pointing at an entire tower came down. Right. And it is pointing at a mid, mid tower section bolted connection. How often do you guys run into those problems? Or are you contacted by insurance companies or anything like that to, to take a peek at those?
Pete Andrews: We haven’t done anything directly for insurance [00:15:00]companies, but we have been engaged by. Engineering consultancies that are doing RCA type activities. Okay. Um, things like at the end of defect liability periods mm-hmm. A customer has, has seen, they’ve had a lot of, uh, issues from an OEM, maybe an OE EM has offered a modification or an upgrade, assessing whether that upgrade is actually solved the problem or not.
We’ve got involved in, um, but the tower. Issue specifically. It’s actually very rare we find, um, problems with tower connections, but where we do is often where they haven’t achieved good flange flatness, ah, during installation or the bolts have been, let’s say, left out in the elements for a period and lubrication has been, has deteriorated before the bolt’s been installed.
So there are cases out there, but what I would say is. [00:16:00] To think about your whole life cycle, so ensure the bolt’s installed correctly and we can help with that with a QA to say, yes, this torque or tightening method has got you to the load that you want. Do some through life monitoring, but often if you install it correctly, it will it’s operational life.
You will have very little concern. But then in the UK market, we’re increasingly getting involved again at the end of life, right? Life extension where life extension turbines are 20, 25 years old. How does an operator make a decision to carry on running without replacing all bots? Um, and that’s where increasingly we being asked to use the technologist just to say, actually the joint is fine.
The bolts have run in a good, um, operational envelope. Run them on. Don’t replace a hundred percent of them like you might have been recommended to from your, um, yeah. Turbine supplier side. [00:17:00]
Allen Hall: So Pete, if someone’s doing a repower where they’re basically putting a new one in the cell on an existing tower, they’re making a lot of assumptions about all the bolts from the ground up that they’re gonna be okay.
And I know we’re talking about that. We’re in a lot of installations where. If the turbine has gone through a repowered or two. So now those bolts are 20 years old. Yeah. And trying to get ’em to
Joel Saxum: 30 35. 35
Allen Hall: 40. Yeah. I don’t know what they’re doing. By those bolted connections. Are they just like replacing the bolts?
Are they hitting ’em with a hammer again? Is that the, yeah,
Pete Andrews: I mean, they might replace ’em, but you’ve got a problem with the foundation bolts. ’cause they’re obviously often anchor bolts set into concrete, so you have to reuse them and. With the projects, both in wind and in process power industry with the chimney stacks to try and ascertain whether foundation bolts that are set into concrete are still suitable for operations.
So look for corrosion losses, look for [00:18:00] defects. Um, so yeah, they’re all things that need thinking about before you just make the snap decision to repower. But I think
Joel Saxum: a lot of that, uh, going back to a couple minutes ago, you were talking about at the commissioning phase, making sure that you have proper qa, QC of how these things were installed day one, and then making sure that before commissioning of a turbine, they’re checked.
I think that’s really important. We’re starting to see that in the blade world now too, where we’ve been talking about it for a long time, and now when you talk to operators, they’re like, we’re getting inspections done on the blades before they’re hung. Or at the factory before they’re hung. After they’re hung.
Like they want a good foundation baseline. Are you seeing that in the bolted connection world too?
Pete Andrews: Yes. Sort of. It’s just emerging for us. What we’ve found is, so most of our customers are in the operational phase ’cause they are the ones feeling the pain. Yeah. Of the routine retitling work. When they do major components, they sometimes engage us to come and say, can you check [00:19:00] before and after the blade was removed?
What was it? Before we took it off from a a bolt load perspective, what is it afterwards? Can you then recheck after 500 hours When we retalk it? And what we’ve seen there often is the initial install hasn’t got them to where they needed to be and they’ve had to go and do the break in maintenance or the 500 hour REIT to get the bolts to the right load.
So one of the questions that we have is whether. Some of the defects are actually being initiated very early on in that initial running in period and whether if, if actually you’d taken the time at, at the point of assembly to make sure you were correct, whether that avoids some of the knock on integrity concerns.
So yeah, it’s interesting area.
Allen Hall: Well, bolts are what hold wind turbines together and you better know you have the right. Tension and [00:20:00] torque on your bolts to get to the lifetime of the wind turbine and to, and to check it once in a while. And I know there’s a lot of operators I can think of right now in the United States that are sort of doing that job somewhat.
I I think they have missed out on opportunities to save a lot of money and to call it echo bolt. How do people get ahold of you? Because that’s one thing I run into all the time. Like, Hey, hey, you gotta talk to Ebol, call Ebol. How do they get ahold of you?
Pete Andrews: So the easiest ways are via our website. Which is echo bolt.com.
Um, LinkedIn, you’ll find us at Echo Bolt on LinkedIn. Reach out. Our email would be info@cobolt.com. So any of those route and you’ll, uh, reach me and the team and more than happy to speak to you about any of your faulting concerns or problems. We are, uh, yeah, we’re passionate about your problems.
Allen Hall: Pete, thank you so much for being on this podcast.
I, it is great to actually see you in person and see the bolt wave technology. It’s really [00:21:00] impressive. So anybody out there that needs bolt tensioning to checking tools, you need to get ahold of Pete at Echo Bolt and get started today. Thank you Pete. Thanks guys. It’s great to be here.
As we’ve noted in the past, the idea of capturing CO2 from the atmosphere is completely unfeasible, since 99.96% of the air around is something other than CO2 (mostly nitrogen). However, there are environments that change this equation radically, cement plants being one of them, where the concentration of CO2 emissions is as high as 30% (versus .04%).
Now, this brings the subject of synthetic fuels into the realm of possibility. Sure, if you want to make gasoline, diesel, and jet fuel, you’ll need two other things: hydrogen (which can come from electrolyzing water), and a considerable amount of energy, as these processes are heavily endothermic, meaning that energy must be supplied from external sources.
The good news is that we have enormous amounts of off-peak wind and nuclear that are wasted every day. Please see: Doty WindFuels.
