Allen Hall: Nicholas, welcome back to the podcast. Hi. Thanks Allen. Good to see you again. There’s a lot going on in wind right now. Obviously the elections that happy the United States are changing the way that a lot of US based operators are thinking about their turbines and, and particularly their blades.
I’ve noticed over the last, even just couple of weeks that. Operators and the engineers are paying more attention to what they’re actually getting on site.
Nicholas Gaudern: Yes.
Allen Hall: Instead of, uh, the sort of the full service agreement where, hey, they’re under warranty for two years, I don’t really need to do anything for a little while approach.
That’s changing into, I want to know what arrives on site, what am I getting and what problems are there with these particular blades that I may not know about because they’re new to me. Even though these blades, there may be thousands of these blades out in service. Mm-hmm. Me, my company doesn’t know.
Yep. How they operate. How they perform, particularly at this, this new site, I’m Repowering or, [00:01:00] or building new. That is a complete shift. From where it was a year ago, two years ago, five years ago. Yeah. And I think the biggest performance piece that people are looking at is aerodynamics, and I’m trying to understand how these blades perform, how they move.
Yes. What kind of loads there are, what kind I expect over the next year or two. And I think they’re just becoming now aware of maybe I need to have a game plan.
Nicholas Gaudern: Mm-hmm.
Allen Hall: And I, and that’s where power curve comes in, is like in the sense of have a king plan. Understand what these plates are all about. Yeah, yeah.
And try to characterize ’em early rather than later.
Nicholas Gaudern: Yeah, exactly. I think there’s been an increased focus on, on data and for operators, as you say, to understand more what they’re getting and not necessarily relying on just what they’re told. So, uh, I think a nice case study of that is last year we were helping a customer to build a, a digital twin.
Uh, of one of their turbine models that they, that they purchased. So what that involved [00:02:00] is, uh, going to site, doing a laser scan of a blade, understanding geometry, helping them to build up some aerodynamic and structural models of that blade. So then that customer was going to build an AEL model themselves of that turbine so that they could run load calculations.
They could look at, uh, site specific, uh, changes that could be relevant to that turbine’s configuration or how they operated it. And this isn’t really something that you saw a lot of, uh, a few years ago, but I think it’s great that operators, particularly when they have a larger engineering capacity, are starting to get into that game.
Uh, and it’s tough because it’s a lot of what the OEMs do, it’s their kind of specialist knowledge, but there’s a lot of smart people out there. Uh, there’s a lot of companies you can work with to help gather that data and build these products up.
Allen Hall: The OEMs right now are. Lowering the number of engineers.
Nicholas Gaudern: Mm-hmm.
Allen Hall: Staff reductions. Yeah. Uh, so getting a hold of somebody on the engineering staff, particularly with aerodynamics, can be quite hard. Yes. And in fact, I’ve talked to [00:03:00] some smaller operators that can’t get access to those people at all.
Nicholas Gaudern: No, no. We, we get told that a lot that, um, there’s, there’s customers calling OEMs and they, yeah.
They can’t, they can’t speak to anyone who really understands that the issues that they’re facing. But free now we, we have contact with a lot of OEMs. I would say that we have more aerodynamicists and power curve than some OEMs have now. Oh, that’s true. And that’s quite, that’s true. Surprising. You know.
Um, so it does mean that I think from a customer support perspective, it is harder for the OEMs to take on some of those really detailed or nuanced questions that an operator may have.
Allen Hall: Right. Operators are getting smarter.
Nicholas Gaudern: Yep.
Allen Hall: And asking more pointed questions, not generic questions anymore. Uh, we’ve had, uh, junker on the podcast and I, when I ran into her last summer, she was basically saying that like you, you’re talking to operators now that are getting smarter about what they’re doing.
Yes. They’re asking more pointed questions. The OEMs can’t respond. So now what do you do? Yeah, that’s, that’s the Global Blade Group.
Nicholas Gaudern: Yeah, exactly.
Allen Hall: [00:04:00] Perspective, right? Where everybody’s starting to pool the resources together. I think that’s an
Nicholas Gaudern: absolutely great initiative. I mean, it’s something that’s been going along in various forms for a few years now, but um, now big it has joined Stack rt.
It’s kind of been relaunched in, in this new form that you were discussing with us. So, um, we are really excited to be part of that, I think kind of the way, uh. Our role sits within the group. We’re still working on, on the details, but we’re definitely gonna be part of that group in helping to, to share knowledge.
So the aim is that we will help, uh, educate basically to, to raise discussion points, to, to lead forums with operators about how they can understand their aerodynamics better, how they can ask more relevant questions of the OEM. So I think that’s what a lot this is about, just asking the right questions.
I think sometimes operators can feel a little bit, uh, blind. Uh, as to the best way to navigate a problem, but by knowledge sharing within the Blades group with other forums, um, I think that’s gonna make that a lot easier for everyone.
Allen Hall: And you’ve been tapped as [00:05:00] the lead of the aerodynamics group within the Global Blade
Nicholas Gaudern: Group?
Yes. Yep, yep, that’s, that’s correct. Um, we haven’t had a, a kickoff yet as such, but that will hopefully happen in the next couple of months. But yeah, the idea is that power curve will kind of. Lead that knowledge sharing around the aerodynamic subject.
Allen Hall: Yes. So if you haven’t joined the Global Blade Group, it’s free.
Yep. If you work for an operator, you can just join it and you should. So get somebody on your staff to sign up to get ahold of Burger and get going with that, because then you can tap into all the resources that they have. Them being, uh, the most recent one is the leading edge protection campaign that was just summarized, uh, a couple of weeks ago.
So that data set is out there and you want to have access to that. Mm-hmm. But I think more importantly, as the group goes forward now and has been emboldened again, the aerodynamic piece is the missing link for most operators. Yeah, it is.
Nicholas Gaudern: And it’s, it’s often an area that is, um, hasn’t had as much attention historically.
Uh, there’s just not so many engineers out there with that background. You know, it’s, um, [00:06:00] I wouldn’t say it’s any more or less hard than lots of other of the complex subjects within a wind turbine. There’s just, there’s fewer people, uh, who, who know the same, uh, level of, um, stuff.
Allen Hall: Yeah. And there’re being, those resources are being, uh, taxed quite heavily at the minute, uh, with all the activity it happen in the OEMs.
Now, as operators, uh, start to receive newer blades and you see. OEMs obviously moving to bigger turbines and to specific models, so there’s actually fewer varieties of blades than there were a couple years ago, but there’s still quite a number of blades out there. Mm-hmm, mm-hmm. So you, you’re going to get generally a more generic blade type at your specific wind site?
Nicholas Gaudern: Yeah, quite possibly.
Allen Hall: Yeah. I, I think especially ge renova is, is gonna be driving down to a, a limited set of blades and a limited set of turbines. So they’re gonna be trying to apply that turbine. More globally than they have in the past, instead of tailoring a specific set of blades vest is, it’s gonna do something very similar, I think.
Mm-hmm. Uh, and in that mode, [00:07:00] if you’re an operator and you’re receiving these blades, you don’t really understand what’s about to happen unless you do your homework ahead of time. And I think that’s where the opportunity lies today to do something really inexpensive and smart up front. To understand what’s likely to happen.
Yeah.
Nicholas Gaudern: Yeah, exactly. And I think that all starts with, um, as we talked about, gathering good data, whether that be a laser scan or detailed photographs or measurements or NDT, uh, putting some sensors in the blade, some CMS equipment. I think all of that stuff to help really build up that knowledge base early.
To help start planning for future o and m, uh, operations? Yeah,
Allen Hall: so the simple one as blades come on site is to do a laser scan.
Nicholas Gaudern: Mm. Yep. And that takes how long? A few hours. And, and it’s much easier on the ground than it is a tower as well. And then you can use that full kinds of things. Yes. It’s very useful to do aerodynamic studies on.
But then, uh, other stuff that might not seem so [00:08:00] exciting, but is super important. How do you move blades around a, uh, handling yard if you have a CAD model that’s much easier to plan? How do you, uh, look at a new stacking frame or a, a lifting device that you might need to purchase? Well, it all comes back to having that initial data.
And I think what we see, uh, at Power Curve is there’s a huge variety of aerodynamic upgrades that are shipped with blades. And even though, um. Two customers might buy the same blade. They might not necessarily have the same upgrade pack on from the, uh, from the OEM. So really understanding what’s in your fleet from the start.
Where are those VGs? Where are the serrations, where are the spoilers? That’s critical going forward to understand how to manage those blades. And we talk to a lot of operators, uh, about VGs and other upgrades. It’s, uh, surprising to us how few know what is on their blades. They just don’t know. They don’t have that information.
They just arrive. Yeah. So, so what happens if some of those add-ons need replacing? What happens if you are missing [00:09:00] potential? Well, you don’t have a good data set to go back to, to really understand the problem. So yeah, we’d really encourage that from the get go to, to document that.
Allen Hall: The, the discussion I’ve seen at operators about trying to get a blade model out of the OEM goes like this, Hey, OEM, uh.
I would like to have the blade model so I can do some analysis and we can operate this thing once it comes off warranty, obviously. And the OM says no.
Nicholas Gaudern: Hmm.
Allen Hall: All right. Well, can I scan it? Yeah, yeah, yeah. Okay. Well, you own the blade at the end of the day. I own the blade so I I can scan it all day. Yeah. But they will not give you the model, but you can scan it.
And scanning’s not expensive. I get it. If they sent you the model, it’d be less expensive. Yeah. But that’s not going to happen. And you can’t even contractually get it because it’s ip. Yeah. Even though you can go scan the same blade.
Nicholas Gaudern: Yeah.
Allen Hall: It doesn’t make any sense why you’re not scanning the blade at this point.
It’s so easy. Five years ago. Yes. Difficult
Nicholas Gaudern: today. Simple. Yeah. The scanning process [00:10:00] itself, I think where the real, uh, complexity comes in is then how do you convert that scan? Into a usable CAD model. I think that’s where the, the experience and um, and the skill of a, a good CAD engineer is really important.
So within, uh, power curve, we’ve been drawing blades for years and years and years now. So 30, 40 different blades we’ve scan, we’ve drawn, we’ve analyzed, and um, even the best laser scan may still have a few question marks around how you should interpret the data. So I’d encourage you that if you are going to go down that path.
Then, then call someone who’s done it a few times before and, and understand what’s going on.
Allen Hall: And then getting the details about the aerodynamic upgrades. I’ll call them quote unquote upgrades because sometimes I wonder if there are upgrades or not. Yeah. Uh, especially VGs getting those identified. It’s exactly where they are on the blade matters.
Trailing ulcerations, the kind of trailing ulceration you have, the sizes of them because they all vary in size [00:11:00] as you go up and down the blade, knowing where those are exactly out on the blade. And to me, when I see a variety of blade, a variety of blades made the same blade model, same blade revision.
Yep. But you start looking at ’em and you see those manufacturing tolerances move around quite a bit. It makes sense not to scan just one blade, but I’m probably gonna scan a variety of blades once they come outside. Yeah. Maybe they,
Nicholas Gaudern: maybe the OEM changes the philosophy about what they wanna do and I think with add-ons, um, there is a lot of, um, design philosophy involved.
With aerodynamics, as with lots of other disciplines, there’s a few ways you can skin the cat, right? There’s different ways that you can have a very similar effect with different products or different configurations, and I think you see that with aerodynamic upgrades quite clearly. So from some manufacturers we see, they’ll ship blades with bgs almost from root to tip.
From from the get go. You’ll see some OEMs that just have them in the route. You’ll have some that have none at all, and that that is still quite surprising, I think, because. Vortex [00:12:00] generators, particularly down in the root region of a blade to me, are, are kind of obvious now they’re proven. Uh, there’s a big stall zone in the root of the blade.
A VG array will help reduce that level of stall. Now you still have to engineer that solution. So perhaps one of the reason we don’t see all blades with them is the OEM didn’t have the capacity to engineer that solution because they didn’t have enough aerodynamics. Or they were too busy working on the next blade or whatever.
But that doesn’t mean that you can’t benefit from those products being there. So this is why it’s important to, to understand what you’re getting and to ask the questions, well, why, why doesn’t the root of my blade have VGs on? Have you done a calculation that shows that they didn’t work? Uh, and if you didn’t, well maybe, maybe you could, or maybe you could talk to someone else.
Um,
Allen Hall: yeah, because you do see the offerings today. And the two obvious ones we see mostly in the states, particularly with VGs and add-ons, is Siemens VGs and trailing inspirations are everywhere. Yeah, all [00:13:00] over those blades.
Nicholas Gaudern: I think Siemens have been for a long time now, uh, very keen on add-ons. And I like that philosophy personally.
I, I think there’s, there’s a school of thought that says if you put an add-on on a blade, you’ve kind of, you’ve kind of failed. You know, you should have addressed in the design that problem, and therefore you don’t need to put an add-on on, but I would make an argument that there are so many things that an add-on product can do that are incredibly hard to achieve in a molded, uh, product.
So even if you think you could include everything in the mold, maybe the cost or the complexity of doing that. Is much harder than just sticking something on afterwards. So I, I don’t think there should be any discussion around it being like a bandaid or a cheat or a fix, or there should be an integrated part of a design process.
A VG will give you more stall margin. So if you design with VGs, maybe you can design your blade, uh, twist distribution a little bit differently. Uh, if you integrate serrations into your design [00:14:00] process, maybe you can change the type of error fo you use or the tip speed ratio that you run at, because the serrations can help reduce the noise.
So if you’re considering all of that from the get go, there’s a lot of power in these devices that are, as I say, are very difficult to achieve in just, uh, out of the mold product. Um, I, I think a lot of operators
Allen Hall: don’t realize how much impact those little plastic devices. Yeah. Can have on, on power production and which is revenue.
Yes. Straight revenue. That’s all that it is. Exactly. And they sort of discount them on some level because they made out of plastic. I don’t know why that is. It’s the, all the engineering and the literally thousands of hours of engineering and being in the wind tunnel, which is super expensive. Yes. To go figure these things out because you can’t calculate them with excel.
No, it’s, it’s way more complicated of a problem than that. You need,
Nicholas Gaudern: you need some higher fidelity tools. And again, I think that’s why there’s been, uh, differing levels of uptake among the OEMs, among different operators because it does require some, [00:15:00] some hard calculations to be done. Maybe some full rotor CFD calculations, but that is all within the grass.
Of what you can do quite economically today. You know, huge increases in computing, power cloud computing services. You can do this stuff
Allen Hall: Well. That’s the thing that I bring up to the operators quite often is I said, you use Chap GPT, right? Yeah. Yeah. And they go, well, yeah, yeah. Well, you realize the amount of compute power that exists behind those, that amount of compute that’s being built today is also gonna do CFD.
Yes. Is also gonna do all those complicated aerodynamic problems and solution sets. That we weren’t really able to do 10 years ago will be instantaneous to us in a couple of months. Yeah,
Nicholas Gaudern: I mean, we work with a, a cloud computing, uh, service, uh, at North. So they’re, they’ve been our cloud computing provider for, for a number of years now to run CFD on.
They’re just building some new data centers now in Denmark, and I believe they said one of them had a rate of power of 250 megawatts.
Allen Hall: Right. [00:16:00] Yeah. They’re having
Nicholas Gaudern: to build, imagine the, imagine the computing power behind 250 megawatts. Right?
Allen Hall: Because as GE Renova has mentioned in a couple of their more recent public, uh, notices, is that gas turbines are a big business for GE Renova for data centers.
Nicholas Gaudern: Yeah.
Allen Hall: And how much data center can you build in a year? Well, evidently about 20 gigawatts worth. Yeah. Quite a lot. Yeah. That’s a lot of compute power. Way more than the planet has ever had before. Yeah.
Nicholas Gaudern: So I think there’s, there’s some, I mean. The work we do, we think we’re quite innovative. We think we’re kind of, uh, leading the way in, in some fields, but we have to be very careful to, to stay on the train because very soon, uh, the computing power that’s gonna be available.
Might blow some of the stuff we are doing now out of the water. Sure will. So we, you know, we need to keep our eye on this fidelity. Yeah. The Fidelity’s gonna go
Allen Hall: way up, but the engineering that goes behind it still has to be there because garbage N equals garbage out. Exactly. You, you have to have people with
Nicholas Gaudern: the experience and the knowledge and the fundamentals because [00:17:00] even with things like vortex generators, there’s so many different ways you can use them.
And I think the two, the two biggest ways, uh, you know, going back to that comment about Blaze being shipped with VGs from root to tip. If you have VGs in the root, they’re fundamentally addressing stall from thick aerofoils. If they’re towards the tip, it’s more about robustness of the power curve, so helping the turbine deal with sub, uh, standard surface conditions, whether that be dirt, bugs, ice, fungus, erosion, whatever.
So even though you may be able to compute all this stuff, some of these fundamental nuggets of knowledge about how these add-ons should work or could work. It’s critical to help set up the problem. And, um, that’s, that’s where we come in hopefully.
Allen Hall: Well, let’s talk leading edge for a minute, just because there’s been a lot of data.
The Global Blade Group has published some five year study from a variety of operators that are trying different kinds of coatings and solutions. One of the things that I get asked weirdly enough is how much can I [00:18:00] possibly lose in a EP due to leading edge? And the numbers that are thrown at me are crazy.
Yes, people will tell me they’re losing 10%. There is no way you’re losing 10%. And
Nicholas Gaudern: that’s, that’s because they’re not using an engineering driven approach. Right. So we’ve, we’ve talked about data capture and, and sensible engineering. It applies to everything. And I think leading edge erosion is an example of something that just has too many reckons involved.
Well, you can actually work it out. Um, you can go to a wind tunnel, you can do CFD simulation, you can do our elastic simulations, and you can come up with a much more, uh, engineering driven and consistent, uh, loss number. So something that we’ve been working on for a long time now in power covers. How do you understand those losses?
And, uh, a year or two ago, we launched our ERA Vista tool, and that is. Uh, designed to take data from the field that real data we’ve been talking about, and combine it with the best engineering knowledge we can [00:19:00] to come up with that loss number. So, uh, a real blade model taken from a real laser scan, CFD simulation, scarda data, coupled into a, uh, a model of a turbine in, uh, in a blade element momentum form.
That is how the turbine would’ve been designed in the first place. So kinda this consistent tool chain. And what we find with leading a ros after analyzing a couple of thousand turbines now with a vista is losses one and a half, 2%. Something in that that’s, that’s a bit more realistic as a loss number.
Those are still significant numbers, but that’s, you should be worried about that number should. You don’t need to have it at 10% to be worried. No 1% on a big turbine is plenty enough to worry about. Right. Especially when you have a hundred of them. Yeah. So, so we don’t need the scaremongering, you just need that consistency and that, um, and that focus on what, what is actually happening and, and can I justify it?
So
Allen Hall: this goes back to a discussion you and I had a, a couple of months ago [00:20:00] about the spreadsheet that’s being shared around that was created at a university that supposedly. Tells us what the, the a EP loss is in an Excel like form. Yeah. That is being used so incorrectly right now.
Nicholas Gaudern: Uh, and it is like any tool, if you, if you use it in a smart way, then maybe you can get a sense of answer.
But trying to do something consistently and to see any kind of real difference between turbine models will be. Very challenging. Yes. Um, so what I like about some of these simple tools is it can help put you in a ballpark, right? That stops us having these silly conversations about 10% losses or 0% losses.
You know, it helps to kind of narrow the band, but if you then want to really understand, uh, what the answer is, much, much closer to reality. Then you have to have the blade data. Yes. Because every blade is different. Every turbine model is different. [00:21:00] You can’t have that generic setup if you want to have that, that subtlety so you can actually spend your money wisely.
Allen Hall: That’s the problem is that that tool’s being used sort of globally across a farm and everybody that’s involved on the engineering side and particularly on the finance side of the operators realizes I’m probably not gonna fix all of these. Yeah. Turbines. A hundred turbine farm, very common in the United States.
200, 300 plus. Now I need to know what turbines I need to go after based on real data. If I have a hundred turbine farm, I really want to pick out the 20 turbines that I’m gonna go put. Leaning as protection on. Yeah. I need to know that, but only when I really know it is to run it through Arab Vista.
And then it does give me the Yeah. The top 20
Nicholas Gaudern: EE Exactly. And that, and that’s exactly what it’s designed to do, to take, to give confident analysis that you can then base business decisions on. Yeah. Um, because there’s a lot of operators out there who would love to optimize how [00:22:00] they’re spending their, their own m budget.
And this tool will allow them to do that. Right. And I,
Allen Hall: I just, I’m starting to see more adoptions at Vista because that accounting
Nicholas Gaudern: Yep. Is starting to take place and then you can start planning for the future as well. Right. So, so let’s say you have five years worth of inspection data that you can run through the system.
You can then see how the AP loss has progressed over five years. Yes. Where’s it going in the future? Uh, maybe I’m finding that my turbines from one OEM are performing way worse than turbines from another OEM. Sure, and that’s just useful information.
Allen Hall: Well, even on the a EP loss from existing leading edge protection systems, some of the more draggy lossy, uh, leading edge protection systems.
Are still being applied today. So as those systems fail, the amount of drag, a lawsuit that is created when the system eventually wear out is way more than just leaving the, the turbine alone, honestly. Yeah. So it’s not, you [00:23:00] need to think of it as a, a, a larger problem. You
Nicholas Gaudern: have, you have to take that system level approach for sure.
Right? You need to think
Allen Hall: about, yes. Okay. Then my blade has say it’s 1% right now I’m gonna put this coating on, but the coating’s gonna last three years roughly generally. What happens at year three? Well, I’m gonna have a 3% loss break.
Nicholas Gaudern: Yeah. May maybe the l break in some, in some cases might make the situation worse.
Right. So, you know, it’s about just choosing the right, the right tool for the problem, isn’t it? It is. When should I put, uh, protection on? When should I not, when should I clean a blade? When should I not? When should I apply VGs? When should I not? But unless you have the data coming in and you have that, uh, setup that we’ve been talking about earlier in the, in the discussion here, that’s really hard to do.
It is. So it’s,
Allen Hall: it’s really hard to do. And even the discussion about leading edge protection, the, the, the issue I have with a lot of them is that they do leave a significant lip Yeah. Right. In a croker area.
Nicholas Gaudern: Yeah.
Allen Hall: Some of [00:24:00] the providers of those systems are, are like, well, it doesn’t really make that much difference.
And they don’t have any aerodynamic data. And I’ve talked to a person that doesn’t know that much about aerodynamics obviously. ’cause there’s only a few handful of people mm-hmm In wind that know that much, but. I think, okay, yes, you’re gonna recover the 1% a EP loss that the blade roughness did have, but you’re not really recovering all that.
No, not necessarily necessarily what a vista will help also tell you, it helps, it
Nicholas Gaudern: helps make a good decision around that,
Allen Hall: right? So you may have a, a preferred LEP solution, but if it really doesn’t change your a EP, then what are we doing?
Nicholas Gaudern: Yeah, exactly. And perhaps the structural implications weren’t that big on that turbine.
Right. So, so yeah, again, having that balance of the structural risk, the aerodynamic risk, I think, um, as you start gathering more and more inspection data as operators are having now that kind of risk, a score based approach where you’re bringing together structural risk, aerodynamic risk, financial risk, um, [00:25:00] and bringing all those things together, that’s, that’s where the money lies.
Allen Hall: The industry is getting smarter. About the way they spend money, which once interest rates went up and they know filter tower on the program. Every episode talks about interest rates and what effect it as. Yes, it does have an effect, but on an engineering group it has a really significant effect because you need to have a better model.
You need to have a better approach. You just don’t throw money at these problems anymore. You need to have an ROI based solution. That’s where Aero Vista comes in. That’s a real solution that’s been validated and has proven itself, and it’s gonna get you to the proper solution, the most cost efficient solution, the fastest way.
I haven’t seen a product out there, and I’ve been around quite a bit. I haven’t seen another product that even approaches that. No, no,
Nicholas Gaudern: I’m, I’m,
Allen Hall: I’m glad to
Nicholas Gaudern: hear
Allen Hall: that one. And it’s not gonna be on the spreadsheet, so if you’re working on a spreadsheet today, stop, pick up the phone, get on the internet. [00:26:00] Look up power curve.
They’re based in Denmark, but they’re worldwide. You guys are everywhere right now and start talking about cost effective solutions. Yes. Start looking at how to spend your money more wisely.
Nicholas Gaudern: Exactly. Exactly.
Allen Hall: Now’s the time to do that. How do people get ahold of you, Nicholas? How do I get people get ahold of power crew.
Nicholas Gaudern: So they can check at our website. That’s, that’s power curve. Uh, dk, we have all our contact details on there. You can look up myself, uh, on LinkedIn. Also our CEO, Neil’s Business Development. Emil, we’re all on LinkedIn. You can reach out there through the website. Yeah, we’d love to talk to you.
Allen Hall: Absolutely. So this year is the year to get your a EP figured out and to get all your add-ons figured out and to get your LEP approach, uh, aligned with the cost.
And I, I think this is the time that Power Curve will be in the lead of this. And hopefully your phone starts ringing a little bit more because we, we’d love to help them do [00:27:00] that. Absolutely. Because I do, I think there’s so much opportunity for operators to save money Yes. And, and to have more production.
Yep. Which is what we need. We need the industry, particularly the United States, need to be able to prove itself more than ever.
Nicholas Gaudern: Yeah. Just use, use the data, use the expertise that’s out there and Uh, absolutely. And uh, yeah, give us a call. Nicholas, thanks for being back on the podcast. It’s been great.
Thanks, Allen.

Allen Hall 2025: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Matthew Stead, Yolanda Padron, and Rosemary Barnes is back this week.
Rosemary, you’ve been to a number of training courses over the last couple of weeks. The first off was GWO. What was your experience at GWO training?
Rosemary1: It was the fourth or maybe even fifth time that I’ve done it. Um, I did it a few times in Denmark and then, uh, this is the second time doing it in Australia. also, this was my first time doing first aid in Australia. Last time they did GWO here, but my first aid was still valid from Europe, so I, I didn’t redo it. And it’s like so much about [00:01:00] snakes and spiders and jellyfish But a good, good rule of thumb, not 100% accurate, but good rule of thumb, if it is something from the ocean that stung you, then you put something warm on it, and if it’s something from the land that stung or bit you, then something cold on it,
Allen Hall 2025: well, how often do you usually take GWO training?
Rosemary1: You gotta do it every two years to be valid. I don’t do it every two years because, um, if you do it every two years, like within two years, then you can do the refresher course. So that’s three days instead of four However, um, because I don’t climb constantly, like often it will be six months or more in between climbs, I’ll just do it before I know that I’ve got a climb.
all the other people except for one were technicians who, you know, have been working for a while.
So they’re also doing the full course, not the refresher. So they get a little bit more practice than I do. But, um, it’s just not often enough. Y-you know, like every time I go it’s like I, I really feel the need to have the refresher, um, because I’m just not fully on top of it. ‘Cause it’s [00:02:00] not just that you need to know what to do. You need to be able to… Like if you need to use it, you’re gonna be freaking out, you know?
This is the worst thing that’s probably ever happened in your life, and now you’ve gotta remember all your training. It’s like you want it to be actually second nature to some extent. So yeah, first day is manual handling, which is v- you know, very– That one’s very easy and I would be happy to never do that again.
Like I will always remember that. Um, then you got fire, um, fire safety awareness, and that one’s just fun ’cause you just get to, um, light fires and put stuff out then first aid, which I definitely always want a refresher on.
The CPR dummies at this place, they had lights, um, and it lit up green if you were doing it right, and I haven’t used a dummy that was so advanced before, so that was quite good. I realized I wasn’t pressing hard enough. and then yeah, last two days is working at heights training, which is the most intense ’cause you got your harness on all day and, um, you know, climbing up and down and rescuing people.
this was Rite Training in Goulburn, and, um, the [00:03:00] instructor’s name was Claire. highly recommend doing that one.
Allen Hall 2025: Is that a general requirement in Australia that you have GWO before you can climb?
Rosemary1: Like, yeah, they will sometimes, um, let you climb if you are babysat by people. I would not recommend other engineers, like if you’ve never climbed a wind turbine before, like I would really not recommend that you just go up with a team and haven’t done the training because you do need to be able to use a ladder safely and, um, you can, y- you can easily, like even inside the nacelle, you could easily hurt yourself really badly if you’re used to working in an office, uh, you’re upping your danger level by, you know, like many, many, many times by going up a turbine and it’s just something that you gotta take seriously.
Allen Hall 2025: How busy are the courses in Australia? Are a lot of technicians trying to get in and get trained?
Rosemary1: No, it’s people that have a job that are getting trained. But there were heaps of techs in this course. There were maybe eight or so, which is also part of the reason why it took a really long time.
Allen Hall 2025: So [00:04:00] this week, as we record, y- you’re presenting a blade repair course for engineers and technicians. a completely new area that you’re, uh, going into in terms of offering advice and expertise that it’s really hard to find on the planet. It’s probably a, a, a busy or, or requested course, I would imagine, in Australia, where you just don’t have access to a lot of the manufacturers.
Rosemary2: it’s a, it’s a course for just for engineers or technical type people, um, but including hands-on stuff. So the way that I I forced this to come into being was just the last five years. I, um, you know, I started working a lot on wind turbine blade repairs and, um, people would ask me, you know, “Have these repairs been done right?”
And the thing is that the only repairs that I had anything to do with when I was working at LM were weirdo ones, right? [00:05:00] Where the normal, like a technician couldn’t, couldn’t handle it. It was outside of, um, yeah, their, their standard, uh, kind of repairs that they can do for whatever reason. and now in the work that we do at Part Load, it’s primarily normal repairs, and I just didn’t know exactly what technicians know. You know, how do they, how do they know whether they can repair it or not? What do they know before they go up there?
When are they calling the engineer? Um, all that sort of stuff, like the normal stuff. eventually it became less about me learning, ’cause like I said, I kind of picked up most of it. Um, but now I’ve got staff that I’m training up to be, uh, you know, composites engineers and to work with these kinds of issues. There’s a lot of repetitive tasks involved in what we do when we, like, assess the condition of a wind farm.
A lot of what we do is look main- manually looking through photos and thing- if things are classified right or not. I [00:06:00] Found this guy from Direct Wind Services, Jurij Eska. He’s a blade engineer. He’s worked in Europe and then come back to Australia, so a little bit like me. And, um, I just worked with him on a few projects and I’m like, “Oh, okay. Well, this guy, uh, he really gets it.” And I asked him, “How do you, how do you train your technicians?
What course do they do? Maybe I can do that course.” And he said, “Oh, we train them ourselves.” And so then I asked him to put this course together. So where we started off the course yesterday, that was, um, uh, an indoor session where I was talking through how are blades designed, uh, certified, tested, manufactured, um, what kinds of manufacturing defects can you see and what do they do about them in the factory?
‘Cause you know that they’re doing a lot of repairs in the factory already before you ever see a, a brand new blade. and then the next three days we’re going to be working on, um, yeah, grinding and [00:07:00] infusions and a bit of a, a bit of theory about, um, composite repairs.
Allen Hall 2025: What do you feel like are those key skill sets that engineers should know how to do, maybe not as well as a, a professional technician that does it a lot, but at least at a beginner’s level should be able to complete them before they start repairing blades on their own and giving advice about how to repair blades?
What, what are those key items?
Rosemary2: part of it is that I want them to be able to understand what is a bad damage and what’s not a bad damage cause you look a lot at images from the outside, but it’s really about what’s on the inside and how deep it goes is the real thing.
So, um, it’ll be about learning, you know, developing some judgment about, um, how bad it can be and how bad it can look on the outside. We’re not gonna be looking at so many real damages ’cause like obviously we’re just dealing with pieces that are in the, um, in the, uh, workshop and Yuri has [00:08:00] made some samples for us, um, purposely made them badly so that we’ve got some, you know, damage to find.
Allen Hall 2025: Are you addressing carbon fiber at all?
Rosemary2: Uh, I actually haven’t asked about that. I don’t think so. Carbon fiber is, um, is a real pain to work with because it’s conductive. Like, even grinding it makes a bit of a hazardous work environment. We did talk a little bit about the different materials yesterday and, um, about pultrusions. And actually, it turns out Yuri used to work somewhere where they, uh, manufactured pultrusions, and I had always, I was always under the impression that a pultrusion is, you know, like, perfectly s- perfectly straight.
That’s the point. And he’s like, “No way.” No way. There’s waviness in the pultrusions
Allen Hall 2025: And on March 3rd through 5th at WOMA 2027, Rosie, you’re gonna give part of this course as part of WOMA, right?
Rosemary2: Little, little mini course. We’ll have to decide what, what makes sense to include, ’cause it was… Yeah, I went through really a, a fair [00:09:00]bit about blades yesterday, you know, like why they are shaped the way that they are. So we had to talk about aerodynamics and, um, why they’re made of composite. So we had to talk about, you know, like composite materials, like how, how they, how they work So I don’t know if, uh, people wanna write in comments that m- we should, we should do some sort of, um, poll beforehand to see what are the topics that are most interesting to people, ’cause I think we’ll have a half day, right? So we’ll need to be, we’ll need to be focused.
Allen Hall 2025: the description of repairs and what repairs should look like could be tremendously valuable. Everybody who has seen a repair always wonders, “Was that repair done right?” And s- and if you can have some general tools to know, like, “Uh, maybe there’s something not quite right here,” or, “That looks like a solid repair,” that would be a tremendous help to the industry, p- particularly for asset managers
Rosemary2: Yeah. And you know what I think is even more useful than being able to pick out when it’s wrong is to be able to know when it’s right. You can– Y-you know, like it is so– [00:10:00] It’s such a relief. Like it takes such a mental load off you when you’re just like, “Yeah, that’s all, that’s all good. That’s normal. Okay, I know that that– I knew that that would happen, so this is not a surprise.”
‘ know, once you know you can make that judgment, you can do it very quickly and focus your attention where it should be, so you don’t need to stress for an hour over every repair. You’re just like, “Yeah. Good, good, good, good, good.” And then, “Mm, please explain why you have chosen to not, not repair this, but just put a Band-Aid over it.”
that’s the goal of this training is to get everybody, y-you know, technical people, not people who wanna ever be a blade repair technician. They’ve got their own training that covers what they need to know. But this one is just, yeah, getting people like asset managers or my employees to learn what they need to know about composites, given that they have already got a strong engineering education.
So, um, you know, they know a lot of the stuff, but just need to know the composite-specific stuff and wind turbine blade-specific stuff
I will run this course again, by the [00:11:00] way, ’cause there was a lot of people who wanted to do it I couldn’t fit in. So it’ll happen at least once. I’ll keep on running it until everybody that wants to do it has, has done it. But, um, yeah, feel free
to get in touch

Allen Hall 2025: [00:12:00] Well, over in Canada, they just approved a, really a wind farm big enough to power a small city, and almost none of the electricity is going to the grid, which is a very interesting aspect to some of the things that are happening in Canada at the minute.
So up in Nova Scotia, uh, they’ve conditionally approved the Ocean Lake Wind Project. This’d be the largest wind farm in the province’s history. Up to 158 turbines will rise, uh, generating as much as 1.2 gigawatts of power. But this power is not headed to households in Canada. Nearly all of it will be feeding Everwind Fuels’ green hydrogen and ammonia plant at Point Tupper, where clean electrons will become a fuel that can be shipped across the ocean to Europe. And Matthew, there’s been a lot of [00:13:00] projects like this in Europe that have stopped more recently, particularly in northern Europe and up in Scandinavia, uh, on the hydrogen side. Or at least they’ve slowed them down. Canada seems to be going into that breach maybe to fill that void. And is there a marketplace for this to occur up in Canada?
Matthew Stead: Yeah, I think it’s very interesting. Um, you know, like you say, a number of canceled projects, and in Australia there’s been numerous canceled projects. So I like, um, the analogy or use of the term hopium rather than hydrogen, um, where, um, everyone’s hoping hydrogen will be the answer. Um, although, you know, what I, what I’ve read and understood is that, um, you know, the commercials just don’t really stack up and, um, yeah. So in terms of South Australia anyway, um, there was some major, um, hydrogen, uh, development planned with, um, you know, it, it never stacked up. So, you know, it sounds like a great [00:14:00] idea, um, but I’m not sure that the commercials will ever stack up unless you’ve got that guaranteed offtake for the, for the ammonium
Allen Hall 2025: Yolanda, what kind of uphill battle is this to get this wind farm up and running knowing that it’s one customer and that commercial market is a little shaky at the minute?
Yolanda Padron: what we saw, they have a lot of ca- caveats, right? So they’ve, they need to secure the customers before they start building and before they do anything, um, behind the meter. But it’s, I mean, it’s, it’s a pretty big wind farm, and it’s pretty far up north. But I mean, we, we talked to someone in, in northern US today who was having icing issues.
So I mean, of course we know Canada is no, no stranger to that, if they do make it work, I think it’d be really, really exciting to, to have sort of one technology power another, um, instead of just what we’ve been hearing a lot of the potential data centers and, and just wind po- [00:15:00] powering data centers.
Matthew Stead: Why not data centers? You know, seriously, like you said, Yolanda. why not go something that does have commercial demand?
Yolanda Padron: we’ve talked a lot about the potential of da- data centers, right? And we’ve talked a lot about people wanting to do them. Um, but there’s also a lot of talk of potentially doing data centers up in space and a lot of talk of maybe what if we do it offshore or, you know. And so I think there’s a lot of what ifs with data centers.
Of course, there’s a lot of what if with this, but just from a technology standpoint, I think this is really intriguing to have something that’s, that’s a little bit even more out there than what we’ve heard so far
Allen Hall 2025: Is it a build it and they will come type of s- situation here that hydrogen and ammonia may be the, the first offtake, but realistically, if that doesn’t work out, they can still connect to the grid and feed Canada, feed the Northeast of the United States or something else
Matthew Stead: Also, um, like Japan has [00:16:00] also expressed strong demand for, um, ammonia, and so, you know, they- they’re on the East Coast, aren’t they? So, you know, shipping it from East Coast to Japan is not gonna be so, so easy. I stick by what I said before. It’s hopium. it’s not a plan
Allen Hall 2025: I just saw an article today talking about Airbus continuing on with a hydrogen aircraft, and I think they were gonna work with a Japanese firm to work on that together. Six months ago I thought that died, but maybe it’s still in the offering. Maybe there’s an offtake for hydrogen. B- besides the, you know, replacement for some of the, uh, more unpleasant gases that are used in steel production and in some other industry things, maybe part of this is airplane fuel.
Which ammonia is one of those offerings also, right? The, there’s been a number of efforts to turn ammonia fuel into essentially jet fuel. They configure the engines to burn ammonia, which is a possibility. It does seem remote though, [00:17:00] honestly. There doesn’t seem to be a huge pull for hydrogen, and there’s not a, a major market for ammonia at at least at the moment.
So I don’t know. It, it’s… When you’re talking about gigawatts of capacity you’re gonna build, you, you hopefully have an offtake
for it
Yolanda Padron: if they designed it for it being not connected to the grid, right, it just is kind of like a behind the meter thing, and then could they later retrofit it into there? Like, how would all that permitting and everything
Allen Hall 2025: I–
well, that’s a great question. I– There are a number of, uh, connections between the United States and Canada at the moment. guess is that when they place this wind farm, they have that alternate route lined up, just like any wind farm in here in the States, that you’ll find them real close to high-voltage transmission lines.
Generally, those are the easy ones because transmission lines cost money and take time for permitting. I’m not sure Canada has those kind of restrictions, right? But Nova Scotia is not the easiest place in the world to do heavy construction work, just the [00:18:00] nature of Nova Scotia. It will be fascinating to see how they progress with this, but it’s something to keep an eye on because a lot of other projects like this have slowed down
Matthew Stead: Do you remember when some of the OEMs were talking about, um, putting electrolyzers on their offshore wind turbines? So the, the theory, the theory was you’ve got offshore wind turbine, you don’t connect it to the grid standalone, um, and you generate hydrogen or, uh, possibly ammonia on the actual wind turbine.
And then every now and then you just decant it, you know, drive up with a boat, you know, plug in the hose, and then suck out the hydrogen or ammonia. So, um, yeah, once again, all of those have gone quiet, haven’t
they?
Allen Hall 2025: speaking of Japan, a global oil giant is walking away from the Japanese offshore wind project, uh, but the project’s not dying. BP has told its Japanese partners it intends to withdraw from a wind farm planned off Yamagata Prefecture, uh, apparently worried about [00:19:00] profitability. The 450-megawatt project sits, uh, just off the coast, and it is led by trading house Marubeni, which says it will press ahead without BP.
Kansai Electric and Tokyo Gas remain on board also. So BP’s exit follows really a, a brutal year for Japan, where Mitsubishi has, and some others, have pulled out of, uh, at least three projects so far, uh, over rising construction costs, and I think a lot of that’s tied to inflation. Uh, the ambition’s still there for, uh, for a number of companies, but it’s just getting harder and harder to do projects in Japan.
Is this just the nature of the economy in Japan at the moment, or is this more about Japanese policy on the offtake,
Matthew Stead: I, I’m not really deep into the details but, you know, it just appears to me like a blip. I mean, there, I think there’s a lot of commitment in Japan to, you know, carry [00:20:00] out their offshore developments and I, I think this is probably more just a blip, um, and a little, you know, internal corporate, you know, argument rather than a sustained issue on offtake agreements and so forth
Allen Hall 2025: Well, Yolanda, how hard is it to keep partners on a wind development in general? Are there a lot of moving pieces there until the turbines hit the water or hit the
earth?
there’s
Yolanda Padron: I think a lot of moving pieces, but not, uh, I haven’t seen a lot of changes once it’s been publicly announced and everything’s, you know, everything’s been signed and everything. Um, I do think this is really interesting. I know we’ve talked a lot about, about having, about the idea of like sometimes people think wind’s really expensive, and the way that we’re gonna make wind work is just making it cheaper for everybody and just optimizing it as much as possible, um, and, and just being, having the turbines be as resilient as possible, right?
And I think such a strong player just backing out maybe [00:21:00] will incentivize some of the people in Japan to sort of try to see how they can optimize it a little bit more. I’m really excited to see it. I don’t know. It’d be… I think it’d be a nice it
Allen Hall 2025: Isn’t the bonus to offshore wind the price stability? Although the price may be higher today than you may be happy to pay, the stability of that price is a huge leverage point when you compare it to things like oil and gas or natural gas, um, in particular, which are highly volatile, that for electricity, at least you have this fairly steady source at a fixed price that you can plan out 10 years, 20 years, 25 years, maybe even 30 years. And as batteries become more prevalent on the grid, that the math even gets better over the years. Isn’t that the bonus? And, and if [00:22:00] everybody can focus on the long-term effects to the economy is where all the action will be?
Matthew Stead: Yeah, I mean, when I first, um, started looking into wind, you know, 10 plus years ago, I, I won- wondered why. Why would you build offshore with all that expense? And then, you know, it became clear to me just around the, um, you know, the diversity, you know, the, the fact that you might get more wind at times that you don’t get onshore wind, and the fact that it’s more consistent.
Um, yeah, and, you know, so those… I- it’s really a trade-off, isn’t it? Between the capital costs and the, um, more reliable, more consistent, um, offshore wind. So I think, you know, I, I was convinced at the start, I thought it was crazy, but then obviously it’s, it’s a, it’s a… it makes sense
Yolanda Padron: Yeah, I agree. And I think, uh, depending on where you’re having your offshore wind farm, you run into things that you maybe haven’t run into before, right? I know onshore we run into a lot of things in the [00:23:00]US and Australia that we, you know, the, the turbines just maybe weren’t designed for, or there wasn’t a lot of research being done because it was being done in Europe and, and the conditions are really different.
Um, and just the same way, you know, the sea is different in different places. There’s different depths. There are diff- different things that you need to worry about. but yeah, I, I completely agree that there’s a lot more generation, um, offshore. It’s, it’s bigger turbines. Um, there can be bigger, larger costs. You know, if you need to do a blade replacement or something, it, it can get, again, really expensive really quickly. But, but it’s, it’s a trade-off for sure.
Allen Hall 2025: We’re gonna take a quick break, but when we come back, we wanna talk about a place where wind is being fought over versus projects slowing down
[00:24:00] over in the UK, there’s a big fight about offshore wind, and not just about where wind turbines will be planted, but more about how they will affect other wind turbines.
So RWE is defending the UK government’s approval of its three-gigawatt Dogger Bank South project, which won its consent order, uh, basically a month and a half ago. Uh, but the developers next door are taking that approval to court. Equinor, SSE, Vårgrön own the neighboring 3.6-gigawatt Dogger Bank wind farm, and they have filed for j-judicial review.
Their argument is technical, but the price tag is not. They say wake effects, where one wind farm steals the wind from another due to turbulence, could cut their output and cost them between €500 million and [00:25:00] €669 million over the life of their project. That’s a lot of money, Matthew. A half a million euros is not something to ignore.
It looks like this is headed to some judicial court or maybe arbitration. Wake effects, which are actually not that well understood from what I can tell at the moment, there’s a lot of discussion and argument about, uh, how real are they or, or what effect they can have on power output. Uh, there’s a lot of money at stake, and the location of some of these wind farms is pretty close to one
another
Matthew Stead: you know, we always, always talk about, you know, AEP loss and, you know, the, the challenge is actually measuring it. And, um, you know, I’ve heard different numbers, but, you know, plus or minus half a percent of AEP loss, um, appears to me from what– in discussions, you know, the, the limit of what you can actually ever measure on a good day.
Um, I just wonder, I mean, while those numbers, you know, €500, um, [00:26:00] million is a, is a big number, um, but what is that as a percentage of the overall output of that, of that facility? Um, I, I don’t know the answer, but, you know, if, if it’s, you know, half a percent, I think you’d be struggling to, um, struggling to justify that, that wake effect loss.
I mean, you know, going back to what you said, Allen, you know, there are wake effects of some sort, but it’s a question of how much. I mean, that-that’s why aircraft don’t take off, um, too closely, isn’t it? Because there’s wake effects. Um, so it’s definitely a given, definitely a given. Um, but, you know, how much of an impact it truly is.
Um, and I mean, there’s always other variables, you know, variables in the weather, you know, wind patterns, da, da, da, da, da, da, da, and how much do this– does this actually compare to those other, other variables?
Allen Hall 2025: Yolanda, how would you even mitigate wake turbulence on an adjacent wind farm? Are there ways to do that today?
Yolanda Padron: I think the, the aerodynamics, Allen, would [00:27:00] be a lot more in your court than, than in mine.
Matthew does have a really good point. I mean, what are we… With the UK wanting to ramp up offshore as much as they want to ramp up, right? They’re not going to just cancel a large project, and they need to… I mean, it’s not, uh, there’s a finite amount of space, right? So what, I mean, what, what are you, what are you gonna do?
It’s like, it’s what, like, what happens in onshore where you, you really hope maybe that you don’t get a wind farm that’s really, really close by. Um, but you might also want to plan for it. I mean, I know of sites that have le- that lease a little bit of extra land so that way no one else can lease it, or that they can, they can use that to, to travel between turbines.
Um, and it’s, I mean, it’s, it’s kind of… Isn’t it kind of just part of it, part of the trade?
Allen Hall 2025: it has to be, right, at some point. [00:28:00] The question in my mind about all this is how much wake is there? Is it directly impacting the adjacent wind farm? Is there– are there things that can be done to minimize that wake turbulence? I think the answer is yes, but as wind turbine blade designers, I haven’t seen the same level of wake reduction that we have seen more recently in aerospace.
It’s complicated to do some of these things on a wind turbine blade. You’re mass-producing. You’re making a blade a day or a blade in a day-and-a-half timeframe. Are you gonna design this really aerodynamic tip to go on to reduce the wake on a particular wind farm? Probably not, right? So it’s, it’s– is it worth doing that versus the, the cost it would be?
So it’s gonna cost 500 million euros in loss to an adjacent wind farm. Do you put that 500 million into the design effort and the molds and [00:29:00]everything else to make these blades different? Uh, it’s a tight trade-off, right? It– from the engineering side. It may be better settled in the courts, honestly. Just it may be cheaper to do it that way.
Matthew Stead: Uh, I, I was gonna go down a different avenue. I mean, obviously there’s always curtailment. There’s always curtailment due to grid congestion, et cetera, et cetera, et cetera, maintenance. I mean, if they, if they just– when wind is coming from a certain direction, they could just de-rate and, uh, just not absorb as much energy, um, out of the wind when the wind is coming from that sector.
And so that would be a way of, um, not modifying the turbine, just de-rating it under a certain wind condition. I mean, the same thing occurs with noise curtailment all the time. Um, so there’s, there’s noise modes. There could be a, a wake loss mode. We should trademark that
Allen Hall 2025: Well, you know who’s gonna make money out of this no matter what? The
lawyers.
Allen Hall 2025: [00:30:00] Well, in this quarter’s PES Wind magazine, there are a number of great articles, and you can download the entire magazine and all those great articles at peswind.com. There’s a nice little article from Enerpac Tool Group, and if you’re not familiar with them, they make a, a number of tools that are handy in the wind industry.
Uh, and, you know, routine torque checks is kind of a pain, right? And the problem with a lot of those checks is that you have to haul around a heavy hydraulic pump to do it. And so if you’ve ever been to a trade show and seen some of these [00:31:00] pumps, it is a pain. And if you h- have to move around, especially on a w- wind site a lot, you really don’t wanna have a heavy pump that maybe is made for something, uh, more robust.
Uh, and you need something that’s portable. That’s what you really need, right? So the Enerpac Tool Group has really created this, uh, LU series they call. Which is a lightweight, portable, hydraulic pump, which is for intermittent work, which is what happens on most wind sites. It’s intermittent. Uh, so the product line director, Angie Wallace, uh, talks about this and says technician feedback has shaped this new tool, uh, from multiple carrying handles and an upward-facing gauge.
And that is a big thumbs up from me. When you put the gauge on the side of the tool where you can’t see it, such a problem. It’s like they’ve never used it. Well, obviously, the Enerpac has been talking to technicians, and they put the gauge where the technician can actually see it. Uh, and it’s designed to go through towers and, and tight [00:32:00] spaces.
Uh, so this is made specifically for offshore conditions. It’s ruggedized, and it’s a great tool. And a lot of times, Matthew, when you s- see the technicians about and some of the tools they carry, you’re like, man, that is not a good tool for this. That is, that is too much to be hauling around, particularly uptower.
It’s nice that we can see some tools that are designed job
Matthew Stead: I, I’m completely convinced. I, I don’t have much to say. Um, I mean, my, my day job is, um, you know, designing products and working out what products we’re going to, to work on, and, you know, the customer is the main voice you should listen to, um, at least in the first step. So always listen to the customer first, and I think from what you’ve described, customer first, and then develop the product to suit the application.
Yeah, so yeah, I’m convinced
Allen Hall 2025: Yolanda, you’ve seen Interpack on sites, haven’t you? It does seem like I run across them once in a while at some of the US
sites
Yolanda Padron: Every once [00:33:00] in a while. I do gotta say I love the idea of when, like, actual, like, boots on the ground people’s feedback is taken into consideration for, for anything really. And so this is, this just makes me really happy because I think a lot of times, like, as engineers, like, we love the idea of just, oh, I’m gonna do this really cool fancy thing, and then it’s just it- no one can use it, or a very specialized person has to be able to use it.
And so actually doing, you know, modifying a product so that it, it makes sense for the people using it, and I know we’ve, we’ve all talked about it a lot internally and, and we continue to work towards making it easier and easier on, on the people actually installing the product. Like, this is, this is really exciting.
Allen Hall 2025: So if you need a lightweight pump for tightening some bolts uptower, particularly if you’re offshore, take a look at this Enerpac line of LU lightweight series tools. It’s well worth it. And at that same time, you should check out PES Wind magazine. Just go to [00:34:00] peswind.com
