Welcome to Uptime Spotlight, shining Light on Wind. Energy’s brightest innovators. This is the Progress Powering Tomorrow.

Allen Hall: Ed0o and Soren, welcome to the program.

Edo Kuipers: Thank you very much.

Thank you both.

Allen Hall: We have some really exciting news from you, from the field, but first I, I want to start with the problem, which. A lot of operators have right now, which is this blade root, bushing it in or insert issue, which is really critical to blades and you’re the creator of the device that’s gonna save a lot of blades.

You want to talk about what happens? When these blade root bushings fail?

Edo Kuipers: Uh, yeah. What we have seen is that it especially concerns, um, uh, polyester type of blades. And what we see is that, um, bushings and, and, and composites, they are not attached to each other anymore. And after a [00:01:00] while, blades are simply flying off.

That’s the, that’s the whole, that’s the whole problem. Of course. And now going back to the root cause, the root cause here is we are working with, with foes and. The fact is that if you’re working with polyesters, they already have, um, at the, uh, uh, during the process, the curing process, they have already curing shrinkages.

So we have already curing shrinkages, which means we have already initial micro flagging going on, on the interface between the bushing and, and, and, and the limited around it. And that reduces, that reduces the um, surface. Carrying area. And by doing so, because we have less area, surface area that can transfer the loads from the hub, um, from the blades to the hub, eh, we have limited amount of, of years on running.

So we are reducing, uh, the, the amount of years [00:02:00] that the blades are on the, on the, on the turbine safely.

Joel Saxum: This problem is compounding right now simply because there’s a lot of the global wind turbine fleet that’s starting to age. Right. Like we, we, we went through a big push in, you know, the early two thousands, 2000 tens, 2000 twenties to now where, you know, if you look at the country of Spain, we hear that regularly, Alan is, Hey, we’re getting to the end of life.

We’re close to the end of life. Then there’s people saying, what is the remaining useful life? Where are we at? Um, and this is one of those issues where. It can develop rapidly, right? So if there’s an issue, you can, if you catch it in time, great. You’re good. But it can develop rapidly and that can lead to catastrophic losses.

But I guess my, one of the questions I want to ask you, and you guys of course have done some commercial here. Uh, how many turbines do you think are affected by this globally affected by this root bushing issues?

Edo Kuipers: Oh, that’s a good one. If I, if I talk a number of blades at the moment, we are more or less at a ball point figure about 30, [00:03:00] 40,000.

Blades. Wow. Worldwide. So we see many us, we see many in South America and we see also in Southeast Asia, like India. And those blades are running, let’s say from 10 years, 12 years, and some of them also after six years,

Allen Hall: and a lot of manufacturing. Uh, blades happens in multiple sites, right? So if you have a particular OEM wind turbine, you may have a variety of different blades on your site.

You typically do. Some of them are polyesters, some of them may be epoxy, but it’s the polyester ones we need to pay attention to first, right?

Edo Kuipers: Correct. The one we are, uh, concentrating on with our solution are dealing with polyester blades because there we see the problem, especially in the, in the interface layer.

There are also root problems with epoxy types, but they are from a, from a different level.

Allen Hall: So the thing that we’re looking for when we start to see [00:04:00]the problem, so if I’m an operator and I have technicians out in the field and they’re looking at blades from the ground, typically very quickly, what are the first signs that you have problems with the bushings?

Edo Kuipers: What we generally see, the first signs is that there is a cracking going on in the ceiling, which is between the blade. The pitch bearing. So if you go up tower as a surface guy, then then look for those initial cracks, and if you see cracking, cracking in that sealant, then remove the sealant just by with a knife and, and, and go with a fill gauge to see if you’re caping going on between the root lum.

Uh, so between the bushing and the, and the, and the pitch bearing,

Allen Hall: so that sealant or gasket between the blade and the pitch bearing shouldn’t be moving or shouldn’t have flexed it. It shouldn’t have broken. It can flex. It’s made to flex a little bit, but if it breaks, it tells you there’s too much stress [00:05:00] on that sealant.

That’s really the first sign.

Edo Kuipers: That’s really the first sign. Then you still have time, but then you have to start monitoring

Allen Hall: and the, the monitoring is telling you what,

Edo Kuipers: once you. Notice this. What you have to do is, for example, you are positioning a leading edge, uh, under the tensile loading of the dead weight.

Then you measure a cap, then you pitch the blade, eh, that the, that, the, that the, that, that side is down. So it’s, it’s, it’s feeling a compressive loading, and then you can see if there is a difference. So what you’re doing is you’re measuring the variable cap. That’s a static gap, but the variation of the capping due to the, due to its own weight of the blade, and that is a sign that that movement is going on.

Allen Hall: So you’ll see compression versus tension, that gap get larger and smaller. There is always some movement in that gap, but it’s very limited if you, what typically is a threshold where you say. [00:06:00] If it’s beyond a couple of millimeters, that’s a problem. Where is that dimensional gap become an issue

Edo Kuipers: with our present customers?

We are saying, um, um, one millimeter and you have to hoist, uh, hoist the blade down.

Allen Hall: One millimeter is 40 thousandths of an inch. That’s not very much.

Edo Kuipers: If it’s, for example, five millimeters, I mean. It’s, it’s not, you’re in a, in a bad stage that within three months your, your blood, your blade could fly off.

And if you are in, in the range of one millimeter, the nice thing on that is that you have a limited amount of bushings, which needs to be replaced. So you are li limiting the effect of the repair.

Joel Saxum: So, but that’s the big thing here, right? So catching it early, it’s like anything in blades, we talk about this.

We’ve been, we’ve been beating this, this horse for a long time. Catch it early, fix it early, or you’re gonna be in a bad state. Because I mean, the, the, the worst thing that happens here, of course is the safety issue, loss of life or anything like that. But what? But the, [00:07:00] what We have seen blade breaks, blade comes down, hits the tower.

Then the tower comes down, then you’re replacing an entire turbine. And that’s, that’s horrible for the operator, the industry, everything in, in, in general. Um, but if you catch it early, now each blade has de, depending on the model, the make the design, um. 60 to 80 bushings. 60 to a hundred bushings. What’s that number?

Edo Kuipers: Yeah. 92 for example. Or 74 or, yeah. In that area.

Joel Saxum: Right. So, so, and when you, and when your solution is engaged, when the, you have to bring the, bring the blade down tower and then fix it if you catch it early. Are you talking, we’re fixing six of these, we’re fixing 40 of these. What does it usually look like?

Edo Kuipers: It’s, uh, in the, in the area of 24 to 30.

Joel Saxum: Okay.

Edo Kuipers: The nice thing on that, the nice thing is on that if we working with a drilling machine, we can do that in 24 hours drilling. So limited time. Limited time of, of [00:08:00] taking out the bushings. And if we would wait longer and we need to repair 60 bushings, it takes, let’s say 60 hours to, to drill out, so to lower the cost of the repair.

Because it’s like a chain reaction. Once it starts, it, it grows to lower the amount of the repair and the cost of repair, let’s, let’s not wait too long.

Allen Hall: Okay. So that’s a really good input into this discussion because I think a lot of operators assume if I have to do this repair, replace the bushings, I’m replacing a number of bushings regardless of the level of damage, because they’re gonna fail eventually.

But you know, what you’re saying is that. It starts in a highly loaded couple of bushings and spreads from there, if you can, if you can fix or upgrade those particular bushings, then the remaining bushings may be okay.

Edo Kuipers: Correct. Because there is always a highly loaded, like you said, and there’s always a a side which is more tensile loaded, and the other side is more compressive loaded, and especially the tensile loaded part is, is [00:09:00]more severely for the fatigue.

Joel Saxum: The other side of this is a blade replacement. So you’re either gonna, you’re going to have to, you’re gonna do something like this, or you’re gonna replace the blade. And, but now again, we’re talking about this aging fleets remaining useful life, what spares look like out in the field. A lot of these turbines.

Spares are not readily available for them. Right. If we’re talking about, and we’re talking about different markets like you, you ju you guys just executed. We’re gonna talk about this a little bit, but you just executed this amazing project, uh, over in the APAC region. It’s not easy to get blades shipped over there, or like in Australia or South America, like in the States.

We’re kind of lucky people don’t realize this, but we’re kind of lucky that we have a fleet of 75,000 turbines because there are spares around for some things. However, as these blades get older, like nobody’s gonna do you a run of a 12-year-old, 15-year-old blade, it’s what, whatever’s on the ground around the world is what we have.

And that is it Ev And then in composites, again, everything can be repaired, but it’s just how much, what is the [00:10:00] economic case for? So you guys are building that economic case to make this make sense.

Edo Kuipers: A new blade, let’s, let’s. Have the old fashioned prices of 10 euros per kilo or whatever, and you have a blade of 15 tons that will cost you like 150,000 euros.

As a new blade, you already paid for that price. Then you have to do it a second time. It’s not only that, it’s also the waiting time. If you have to wait for one year, your loss, your loss in, in, in, in, in, in revenue. Also, let’s say like 100, 150, maybe 200,000 depending on your feed into reef tariffs that you get.

It’s also, that’s also a loss. So the total thing will cost you already like easily like 200, 300,000 euros for for one turbine, right? Or one for one rot blade. If you do a repair, then there’s a repair. It’ll cost you like a fraction of that. It’ll cost you maybe like 30, 40,000 euros.

Joel Saxum: Yeah. And the reality is, is when you [00:11:00] replace one blade, you normally are replacing all three.

I mean, unless you, unless you can find a, a matching, you know, a good, well you, you get lucky and you find one blade that has the weight certificate and a bending moment certificate that matches your other. Two that are up tower. Mm, pretty rare. More than likely you’re getting all three new blades. So then all of a sudden your 150 turns into 450 before you even start it.

Soren Kellenberger: Absolutely. And that’s, that’s if you can get a replacement blade because if you need to go back to a, a manufacturer Right, they, they will not sell you that blade for the original 150,000 Euros. Uh, so. If they at all have a mold before they get it started up and all the initial cost in, in getting that up and running, you are looking at 2, 3, 4 times the price of the, of the new blade.

So it, it really adds up if you have to replace. And there’s of course also the whole discussion right now with, um, the old blades and all the waste it’s, uh, creating. So from an environmental perspective, it’s [00:12:00] also a huge benefit to, uh, repairs instead have replaced. Uh, but, but the financial is, it’s just, uh, yeah.

Basically a no brainer, right?

Allen Hall: Oh yeah. The financials make total sense. And this is where we’re gonna get to the solution from WE four C, which is called Refit, which is a, a bushing upgrade and the workings together of two separate companies. So we have WE four C, which is, uh, based in the Netherlands of course, and then we.

We have Sorin and CNC onsite, which is based in Denmark, so they’re really relatively close to one another, and both companies are powerhouses in wind and, and fixing wind and making it more efficient and getting our turbines optimized for long-term duration, which. What we in the states have not been doing, but we’re, that’s gonna rapidly change in the next couple of months.

Uh, so this refit solution does make a lot of sense to me just because the demand is [00:13:00] gonna be there and we need to have some way of doing this. And, uh, this is what I want to talk to both of you about, because understanding how to replace these bushings, it, it seems at first, like it’s an impossible task.

You brought two powerhouses together to solve this problem. You wanna discuss how the two companies work together, we foresee and CNC onsite, and how this, uh, repair rework is accomplished.

Soren Kellenberger: I think if we, if we take it back a step, um, we at CNC or uh, onsite was originally involved in a plate repair project.

Uh. Before, actually before the, the Corona uh, uh, situation. Uh, so we had worked on a machine and made some, uh, tests in, in our workshop on this repair, drilling out bushings. Um, then Corona came and the project was stopped and never restarted again. So about four years, pretty much to the, [00:14:00] to the date because it was at the Huon wind, which is now coming up again in, in one and a half week.

Um, we were in, we met, uh, we foresee, uh, so we had this drilling technology sitting there, and I walked around and I saw these, uh, nice, uh, bushings and, and, uh, a couple of nice gentlemen standing there. So I approached, uh, IDO and, and Arnold and said, uh, Hey guys, this, uh, this, this looks nice. What is it? And, uh, we started talking about that.

Uh, they actually had the. Pushing technology ready. They needed someone who could drill out the old ones. And yeah, we had the technology to drill out the old ones and needed someone who could insert those replacement pushing. So it was actually, um, a very, a very good fit. And then the whole corporation just started off basically on trust.

I mean, we signed the NDA and stuff like that, but we just trusted each other and, and moved, uh, forward. And it took some time before getting to the first customer also. What you mentioned in the [00:15:00] beginning, right, Alan, that there’s, yeah, it looks nice, but has it been done before? It’s been, we’ve heard that question, uh, a lot of times.

Um, so it took some time before we got through all the testing and stuff like that, but, uh, now it’s up and running and, uh, works really well.

Edo Kuipers: At the third point, the customer said to us, if you can show a test with this number of cycles and fatigue, it was something like a certain level and a 1 million cycles test.

If you can show that to me, then we will sign the contract. So we sent two coupons, you one to a, to a Dutch Institute, independent, one to a German Institute who was doing um, um, coupon testings. And we said, okay, run it. Run them off both for 1 million cycles. And they had, they had the same result. So, and both, both have reached the 1 million cycles.

So we said to the customers, we did not provide one component with 1 million cycles, but two for you to, to make sure. And also at different test institute. [00:16:00] And then they signed the contract and at all went. Very fast after that.

Allen Hall: Well, yeah, if as soon as you can show the technology works in the laboratory, the next step is to get it deployed.

So the, the, the process works sort of like this. And, and stop me if I’m too far off because I’ve had to explain to me very slowly. Ada has done this very carefully. So let’s see if I can, uh, explain it to the teacher. I’m gonna take, I’m gonna remove the blade off. I’m gonna bring the blade down, and they’re gonna call Soren’s people at CNC onsite.

And they’re going to actually. Have tooling this amazing tooling to drill out this old bushing and make it such that this ados wonderful refit solution can slide into this new drilled spot that’s been perfectly honed. And this new bushing goes in and there’s a bunch of epoxies added behind it to hold that new bushing in place.

And then once that’s done, I move to the next one. And because the system is set up with CNC onsite to have [00:17:00] to go ahead and, and drill out multiple bushings, uh, very quickly, this process, once the blade is down, is actually very quick. So you’re talking about maybe a couple of days total to repair a blade that otherwise would be

Edo Kuipers: discarded.

This is, I’m very happy with this at the moment. And this is also with thanks to the um, uh, to the criteria, to the cap measurements of up tower we are doing. So this is the first step we have to do, of course. But thanks to that we only need a limited amount of bushing. So we are doing, let’s say like 24 to 30 bushings are being drilled out.

This takes us. 24 hours, more or less, we are doing it. We could do it in three shifts, so then it’s one day, but we are not doing it in one sh one shift. They, they are working neatly, they are working accurate and with the same team. And so they are doing three days. After these three days, they are, they are done with the drilling.

Um, then we need to start the [00:18:00] preparations, so the new bushings needs to be implemented. That will take us, let’s say like eight hours of preparations, because everything needs to be far tight and that that is essential for our solution. It needs to be low, far level, so all the air out. And then after this, that takes about eight hours, and after that we have the infusion day.

That’s a really exciting day always, because once. The resin is running. We can’t stop it anymore. Right? So this, this day is also, let’s say eight hours. So, and then we have some finishing because it would be nice if we are hoisting up the blade again. A tower that the, that the root is, is flat. Yeah. All the resin pieces are off.

And we may have to make sure that, uh, that all the, all the bushings are aligned well for the proper load distributions. Um, another, let’s say another few hours, maybe eight hours. So then we are 48 hours, 50 hours of the whole process working with three or four people. That’s it.

Allen Hall: [00:19:00] Wow. And does it take anybody special to be on site from like the CNC onsite?

You know, c NNC onsite makes these great machines that are highly accurate. Uh, Soren, do you need to have specialized people on site or are you training people that are local to do this work?

Soren Kellenberger: We are training local people. So that is, that is part of, of the whole solution that, that we do a technology transfer.

So it’s, people are trained with this specific project. We started by having the, the team in Europe, uh, so they had some, some training days with, uh, IDO and the guys in the Netherlands on the, uh, whole mounting and infusion technology. And then they came to our workshop and trained in operating the drilling machine.

Afterwards. Then for the startup, we send the technicians, uh, to, to the customer, um, who supported for a couple of weeks, and then we went back. Uh, and then we are basically, uh, always ready to support. But on teams or whatever, we can set up a link and, and [00:20:00] a system if needed. They are running with it, uh, very well.

So it’s, it’s been very limited what we’ve had to do. Uh, we get some feedback on the drilling process so we can optimize some parameters and, and step by step, uh, improve the process time. We’ve done some optimizations to the drills, uh, to make them last longer and, and do. Those, uh, things more efficiently, but they are basically running on their own

Joel Saxum: guys.

I think that’s something to make sure that we don’t breeze over here as well. Is the local content part of your solution. So you’ve done all the expert engineering, uh, figuring out the processes, of course, all the, the precision machining equipment from Soren’s team as well, but you can export it to different locales and train up the local staff and get them moving.

So places like it’s, it’s expensive. It’s difficult to get people into South Asia. It’s expensive, it’s difficult to get people into South America, to Australia, to, to anywhere really. You’re gonna export this. However, what you’re also doing is bringing local jobs, local [00:21:00] work, local revenue to the local teams.

And I know that that makes a lot of, a lot of people happy. Um, including, I know, like we’re, we’re sitting in the States, right? There’s a lot of ISPs over here, hopefully listening to this. They’re saying like, Ooh, we’d like to be the people that implement this solution over in the States. Let’s get ahold of these guys.

Uh, so kudos to you on that as well.

Edo Kuipers: Yes. The idea is indeed to have, um, on different regions in the world, uh, different, uh, repair hubs so that we can always work with the same teams, with the, with the, with the same people. So we train them, educate them, and then of course, from the Netherlands and of course from Denmark, we still, we will always support them, but it can also be done by a teams or a conference calling.

Allen Hall: And let’s talk about the Southeast Asia. Project you just completed successfully and uh, it looked fantastic. That was the first major project that you’ve tried this technology on. Besides everything in a laboratory, kind of one off things, but now you’re going to scale. This is a big step. [00:22:00] How did it go?

How did that process start? What did it look like afterwards?

Edo Kuipers: Um, how did it start? Uh, by doing it, I mean, sir and his team went on site, of course, and we encountered difficulties, of course, first time with drilling. And, um, that had multiple reasons. So the guys, uh, even the, the, the, the colleague of Sir went, went back to Denmark.

He changed, he fixed something on a drill, had sent a new type of drill and it ran perfectly. So from there, from that point, the drilling was no problem anymore. Then after we created the holes together, um, of course we have to do the infusion. And going from going from infusing like five bushings in a row, we had to go to 30 in a row.

And that was in the beginning, quite challenging. Um, to have, so it was a little bit like keep your fingers crossed if everything is going fine, but it works somehow. Um, it works [00:23:00] and, and all the resin came out. So we are quite happy with that. Uh, of course there are some fine tuning in the processing in the quality.

Uh, but that’s, that’s important for us is, is, is to keep, you need to keep following the. The quality processes. If you, if you strictly follow the quality processes, make sure it’s vacuum tight, make sure that you work in sections, so don’t open your resin folds all at the same time, one by one correctly.

And then just monitor and make sure that, of course, refresh your resin from time to time. Because that’s a pot life thing, and it takes, let’s say like maybe two hours before the whole resident is going through the bushing and also in the depth direction that is being impregnated well. Um, so you have to make sure that your pot life is under control.

And also we work with a tent, which is like 100 square meters, which is air conditioned, and, and that all contributes to a, [00:24:00] a controlled process. And yeah, that was very scary for the first time. I must admit that if you do second time. You get more relaxed. And the third time, it’s like driving a car the first time.

Oh, this, I need to pay attention to the gear. In the, in, in Europe, we have gears and, um, on the car and um, we, we need to, we need to drive and look around us and the navigation system. Um, so, and at a certain point it’s all going automatically. Right. How many blade did you repair in Southeast Asia? 18. Now we are working the, the, the sixth set.

Set number six has just completed, and I know this every week, I have contact, uh, with, with, with, with. With. With one guy there. It’s, it’s, we know each other good. So he, he gives us the feedback and it costs me every week. It costs me half an hour, not more.

Joel Saxum: It’s usually not one blade. It’s usually the whole step has an issue, correct?

Edo Kuipers: Yes and no. Um, what they do now at the moment, um, they, they, [00:25:00] they, they, they see that one, one blade has, um, uh, a problem. So they, they, they already. Start thinking ahead by taking all three blades down. So even if, if one or two blades within the set does not have the variable capping, they know in half a year it will happen.

That’s the experience they already have. And the the, there is the certain. They have a certain agreement here with the crane. The crane is coming, let’s say they use a crane every month for a fixed period. So they say, let’s hoist the complete set down. Then we have three weeks to repair, and in the fourth week we will hoist it out again.

Joel Saxum: Yeah. And the, and the technicians on site, once they’re trained up, uh, they’re loving it because whether it’s in the hot in South, south Asia, or if you’re doing this in the cold, you’re working in a tank. So if they got an extra couple blades to work on as a blade technician. I’m all for it. I’m all for it.

A little bit more time in the AC or in the heat and nice kind, controlled facility. It’s,

Soren Kellenberger: uh, I think the, the guys will like that a lot in the [00:26:00] field. One of the benefits you, you get also is, as Ido mentioned in, in the beginning, if you catch it early, you have fewer, uh. Bushings to repair. So, uh, you, if you catch it or, or repair it while you have your blades down already, you can repair fewer bushings.

And in terms of process time, it’s also a little bit faster. That’s also what we learned to, uh, to drill out the bushings when they are not. Too loose. Um, the more loose they get, the more risk you have of vibrations when you start drilling and that can potentially damage your drills. Uh, um, and it, it just adds to the process time.

So. There are a lot of benefits by catching these, uh, things early and getting the process, uh, completed at an earlier damage stage.

Allen Hall: Now you’ve completed your first big project. What’s next? It sounds like there’s a lot of opportunity worldwide to do this refit process.

Edo Kuipers: Yeah, we, the, the, the first, the first [00:27:00] team is the, is our number one team.

You can see it also here on the, on the breast. And, um, we are now looking basically a number two team, which is, is as excellent as the number one team. Um, so yeah, it’s not only that, um, we have to do, I mean. If you would like to have this, this technology implemented, um, it’s, it’s going Pfizer versa. So, um, very, very important is that we are working together with teams, service teams, which 100% trust each other.

That’s where it starts already. Um, and they are fixed. So if, if you have fixed teams, you teach them and they, they, they, they, they, they learn by experience and that that’s how it should be. Um, so yeah. The next step is, is we are talking with. Next step is we are talking with different, uh, potential, um, service companies, um, worldwide.

So we are talking within America with, with one or two, um, potential, um, good guys, good [00:28:00] groups. Um, the same in, in India, for example, and the same in, in, in South America. That’s, that’s our aim to have, let’s say in, in South America. Two service companies, uh, in, in, in India, two or three, uh, um, in India, in America, one, two, or three or whatever.

So that’s, we are now discussing with these parties, and it’s not only one direction, okay? We want to sell it to you. Now, it’s also the other direction. Are you capable? How do we want to work with 24 hour cycle? Do you have a place where we can install everything? So that’s our next step to explore.

Allen Hall: Yeah.

And Sorin, you have to start making more machines. I hope so.

Soren Kellenberger: No, it’s, it’s definitely, we’ve, we’ve seen a lot of interest and, and we’ve also had numerous contacts over the years. But again, it’s been back to this, have this been done before and. It sort of, no one wanted maybe to be the first, but now the first commercial project is, is out there.

It’s, it’s still [00:29:00] ongoing. And, and once this is completed, we will have installed more than a thousand bushings. Uh, so, so I think it’s, it’s a decent. Proof of concept. It’s a, it’s a real case. It’s not just one blade or one set. It’s, it’s actually a, a, a larger farm that, where, that we have, will have repaired once, uh, this project is, is, uh, 100% completed.

So it’s, it’s going really well. Uh, and I think that of course they will, once the potential customers see that, that this project is now open and running, it will move forward with, uh, contracts for, for other projects. But who is gonna be the first is still, uh, difficult to say, but, uh, I’m pretty sure that, that there will be more.

Edo Kuipers: Yeah. We would also quite be keen on getting on the table with the big OEMs because there are many parks which have still some kind of, uh, service contract, eh, uh, full service agreement or whatever. So even if park owners, many time [00:30:00] park owners say to us, Hey, we would like to have your technology implemented because that sounds to be the most robust one.

Um, but you need to convince the, the, the, the, the Big O oms. Um, and sometimes that is, that is, that is a difficult part because you need to go through, through these different steps with a lot of decision makers, uh, in these organizations. And that takes time. So request is, are on these big, OMS is to define clear criteria for us.

How, what should be, what should we fulfill? And if we fulfill this. Basically, do we then have a deal with each other? Because in the end, for us, we need to help those park owners because they are in the end, eh, um, they have the, they are feeling the pain on, on, on, on this kind of, um, yeah, sometimes hidden problems.

Allen Hall: Well, if you’re an OEM or an operator, where do you start this process? Who do you call first? Do you call we foresee or do you call CNC onsite or does it matter?

Soren Kellenberger: Call either of us and, uh, we [00:31:00] will be, make sure to, uh, involve the other parts. So that’s where the trust and cooperation comes into play. Uh, yeah, just reach out and, uh, we will, we will.

Set up joint meetings.

Allen Hall: The website for CNC onsite is CNC onsite.dk because they’re in Denmark. And the website for WE four C is we the number four, letter C, letter e.eu. And either one of those addresses will get you to the information you need about the refit and. Uh, get you started because as we’ve seen the United States, a lot of things are changing and worldwide.

We need to keep these turbines up and running longer. The way to do that is to put a little bit of money into them now instead of spending a whole bunch of money later. This is why we love we four C and C and C onsite because they’re saving operators, literally millions of dollars. So. You know, and Soren, thank you so much for being on the podcast.

We, we love having you. And as you finish up the Southeast Asia project, you gotta come back on after you [00:32:00] finish those thousand bushings and give us an update. Absolutely. We’ll be happy to.

Edo Kuipers: Yes, thanks a lot. We are fully happy to.

Trump’s Destruction of Renewable Energy Benefits His Support Base, and That’s All that Matters

Published

on

The death sentence that Trump has imposed on renewable energy in America is good for two groups: a) Big Oil and b) the MAGA crowd that rejects science and wants nothing more than to own the libs, aka “libtards.”

The unforeseen problem for the common American is that solar and wind are by far the least expensive sources of energy, so that the ratepayers in the U.S. are soon going to be shucking out huge amounts of extra cash each month.

Of course, this doesn’t account for the increases in the effects of climate change that, though they are devastating our planet, won’t be affecting the folks in Oklahoma too badly for the next few years while Trump does his best to profit by turning our Earth into a wasteland.

[00:00:00] The Uptime Wind Energy Podcast brought to you by Strike Tape protecting thousands of wind turbines from lightning damage worldwide. Visit strike tape.com and now your hosts. Welcome to the Uptime Winner Energy podcast. I’m your host, Alan Hall. I’m here with Yolanda Pone, Rosemary Barnes, and the Blade Whisperer, Morton Hamburg.

And we’re all in Melbourne at the Pullman on the park. We just finished up Woma 2026. Massive event. Over 200 people, two days, and a ton of knowledge. Rosemary, what did you think? Yeah, I mean it was a, a really good event. It was really nice ’cause we had event organization, um, taken care of by an external company this time.

So that saved us some headaches, I think. Um. But yeah, it was, it was really good. It was different than last year, and I think next year will be different again because yeah, we don’t need to talk about the same topics every single year. But, um, yeah, I got really great [00:01:00] feedback. So that’s shows we’re doing something right?

Yeah, a lot of the, the sessions were based upon feedback from Australian industry and, uh, so we did AI rotating bits, the, the drive train blades. Uh, we had a. Master class on lightning to start off. Uh, a number of discussions about BOP and electrical, BOP. All those were really good. Mm-hmm. Uh, the, the content was there, the expertise was there.

We had worldwide representation. Morton, you, you talked about blades a good bit and what the Danish and Worldwide experience was. You know, talked about the American experience on Blades. That opened up a lot of discussions because I’m never really sure where Australia is in the, uh, operations side, because a lot of it is full service agreements still.

But it does seem like from last year to this year. There’s more onboarding of the technical expertise internally at the operators. Martin, [00:02:00] you saw, uh, a good bit of it. This is your first time mm-hmm. At this conference. What were your impressions of the, the content and the approach, which is a little bit different than any other conference?

I see an industry that really wants to learn, uh, Australia, they really want to learn how to do this. Uh, and they’re willing to listen to us, uh, whether you live in Australia, in the US or in Europe. You know, they want to lean on our experiences, but they wanna, you know, they want to take it out to their wind farms and they ga then gain their own knowledge with it, which I think is really amicable.

You know, something that, you know, we should actually try and think about how we can copy that in Europe and the US. Because they, they are, they’re listening to us and they’re taking in our input, and then they try and go out. They go out and then they, they try and implement it. Um, so I think really that is something, uh, I’ve learned, you know, and, and really, um, yeah, really impressed by, from this conference.

Yeah. Yolanda, you were on several panels over the, the two days. What were your impressions of the conference and what were your thoughts [00:03:00] on the Australia marketplace? I think the conference itself is very refreshing or I think we all feel that way being on the, on the circuit sometimes going on a lot of different conferences.

It was really sweet to see everybody be very collaborative, as Morton was saying. Um, and it was, it was just really great about everybody. Yes, they were really willing to listen to us, but they were also really willing to share with each other, which is nice. Uh, I did hear about a few trials that we’re doing in other places.

From other people, just kind of, everybody wants to learn from each other and everybody wants to, to make sure they’re in as best a spot as they can. Yeah, and the, the, probably the noisiest part of the conferences were at the coffees and the lunch. Uh, the, the collaboration was really good. A lot of noise in the hallways.

Uh, just people getting together and then talking about problems, talking about solutions, trying to connect up with someone they may have seen [00:04:00]somewhere else in the part of the world that they were here. It’s a different kind of conference. And Rosemary, I know when, uh, you came up to with a suggestion like, Hey.

If there’s not gonna be any sales talks, we’re not gonna sit and watch a 30 minute presentation about what you do. We’re gonna talk about solutions. That did play a a different dynamic because. It allowed people to ingest at their own rate and, and not just sit through another presentation. Yeah. It was made it more engaging, I think.

Yeah, and I mean, anyway, the approach that I take for sales for my company that I think works best is not to do the hard sell. It’s to talk about smart things. Um, and if you are talking about describing a problem or a solution that somebody in the audience has that problem or solution, then they’re gonna seek you out afterwards.

And so. There’s plenty of sales happening in an event like this, but you’re just not like, you know, subjecting people to sales. It’s more presenting them with the information that they need. And then I, I think also the size of the conference really [00:05:00] helps ’cause yeah, about 200 people. Any, everybody is here for the same technical kind.

Content. So it’s like if you just randomly start talking to somebody while you’re waiting for a coffee or whatever, you have gonna have heaps to talk about with them, with ev every single other person there. And so I think that that’s why, yeah, there was so much talking happening and you know, we had social events, um, the first two evenings and so.

Mo like I was surprised actually. So many people stayed. Most people, maybe everybody stayed for those events and so just so much talking and yeah, we did try to have quite long breaks, um, and quite a lot of them and, you know, good enough food and coffee to keep people here. And I think that that’s as important as, you know, just sitting and listening.

Well, that was part of the trouble, some of the conference that you and I have been at, it’s just like six hours of sitting down listening to sort of a droning mm-hmm. Presenter trying to sell you something. Here we were. It was back and forth. A lot more panel talk with experts from around the world and then.[00:06:00]

Break because you just can’t absorb all that without having a little bit of a brain rest, some coffee and just trying to get to the next session. I, I think that made it, uh, a, a, a more of a takeaway than I would say a lot of other conferences are, where there’s spender booze, and. Brochures and samples being handed out and all that.

We didn’t have any of that. No vendor booze, no, uh, upfront sales going on and even into the workshop. So there was specific, uh, topics provided by people that. Provide services mostly, uh, speaking about what they do, but more on a case study, uh, side. And Rosie, you and I sat in on one that was about, uh, birds and bats, birds and bats in Australia.

That one was really good. Yeah, that was great. I learned, I learned a lot. Your mind was blown, but Totally. Yeah. It is crazy how much, how much you have to manage, um, bird and wildlife deaths related to wind farms in Australia. Like compared to, I mean, ’cause you see. Dead birds all the time, right? Cars hit [00:07:00] birds, birds hit buildings, power lines kill birds, and no one cares about those birds.

But if a bird is injured near a wind farm, then you know, everybody has to stop. We have to make sure that you can do a positive id. If you’re not sure, send it away for a DNA analysis. Keep the bird in a freezer for a year and make sure that it’s logged by the, you know, appropriate people. It’s, it’s really a lot.

And I mean, on the one hand, like I’m a real bird lover, so I am, I’m glad that birds are being taken seriously, but on the other hand, I. I think that it is maybe a little bit over the top, like I don’t see extra birds being saved because of that level of, of watching throughout the entire life of the wind farm.

It feels more like something for the pre-study and the first couple of years of operation, and then you can chill after that if everything’s under control. But I, I guess it’s quite a political issue because people do. Do worry about, about beds and bats? Mm-hmm. Yeah, I thought the output of that was more technology, a little or a little more technology.

Not a lot of technology in today’s world [00:08:00] because we could definitely monitor for where birds are and where bats are and, uh, you know. Slow down the turbines or whatever we’re gonna do. Yeah. And they are doing that in, in sites where there is a problem. But, um, yeah, the sites we’re talking about with that monitoring, that’s not sites that have a big, big problem at sites that are just Yeah, a few, a few birds dying every year.

Um, yeah. So it’s interesting. And some of the blade issues in Australia, or a little unique, I thought, uh, the leading edge erosion. Being a big one. Uh, I’ve seen a lot of leading edge erosion over the last couple of weeks from Australia. It is Texas Times two in some cases. And, uh, the discussion that was had about leading edge erosion, we had ETT junker from Stack Raft and, and video form all the way from Sweden, uh, talking to us live, which was really nice actually.

Uh, the, the amount of knowledge that the Global Blade group. Brought to the discussion and just [00:09:00] opening up some eyes about what matters in leading edge erosion. It’s not so much the leading edge erosion in terms of a EP, although there is some a EP loss. It’s more about structural damage and if you let the structure go too far.

And Martin, you’ve seen a lot of this, and I think we had a discussion about this on the podcast of, Hey, pay attention to the structural damage. Yeah, that’s where, that’s where your money is. I mean, if you go, if you get into structural damage, then your repair costs and your downtime will multiply. That is just a known fact.

So it’s really about keeping it, uh, coding related because then you can, you can, you can move really fast. You can get it the blade up to speed and you won’t have the same problems. You won’t have to spend so much time rebuilding the blade. So that’s really what you need to get to. I do think that one of the things that might stand out in Australia that we’re going to learn about.

Is the effect of hail, because we talked a lot about it in Europe, that, you know, what is the effect of, of hail on leading edge erosion? We’ve never really been able to nail it down, but down here I heard from an, [00:10:00] from an operator that they, they, uh, referenced mangoes this year in terms of hail size. It was, it was, it was incredible.

So if you think about that hitting a leading edge, then, uh, well maybe we don’t really need to, we don’t really get to the point where, so coding related, maybe we will be structural from the beginning, but. Then at least it can be less a structural. Um, but that also means that we need to think differently in terms of leading edge, uh, protection and what kinds of solutions that are there.

Maybe some of the traditional ones we have in Europe, maybe they just don’t work, want, they, they won’t work in some part of Australia. Australia is so big, so we can’t just say. Northern Territory is the same as as, uh, uh, um, yeah. Victoria or uh, or Queensland. Or Queensland or West Australia. I think that what we’re probably going to learn is that there will be different solutions fitting different parts of Australia, and that will be one of the key challenges.

Um, yeah. And Blades in Australia sometimes do. Arrive without leading edge protection from the OEMs. [00:11:00] Yeah, I’m sure some of the sites that I’ve been reviewing recently that the, the asset manager swears it’s got leading edge protection and even I saw some blades on the ground and. I don’t, I don’t see any leading edge protection.

I can’t feel any leading edge protection. Like maybe it’s a magical one that’s, you know, invisible and, um, yeah, it doesn’t even feel different, but I suspect that some people are getting blades that should have been protected that aren’t. Um, so why? Yeah, it’s interesting. I think before we, we rule it out.

Then there are some coatings that really look like the original coating. Mm. So we, we, I know that for some of the European base that what they come out of a factory, you can’t really see the difference, but they’re multilayer coating, uh, on the blades. What you can do is that you can check your, uh, your rotor certificate sometimes will be there.

You can check your, uh, your blade sheet, uh, that you get from manufacturer. If you get it. Um, if you get it, then it will, it will be there. But, um, yeah, I, I mean, it can be difficult to say, to see from the outset and there’s no [00:12:00]documentation then. Yeah, I mean. If I can’t see any leading edge erosion protection, and I don’t know if it’s there or not, I don’t think I will go so far and then start installing something on something that is essentially a new blade.

I would probably still put it into operation because most LEP products that can be installed up tower. So I don’t think that that necessarily is, is something we should, shouldn’t still start doing just because we suspect there isn’t the LEP. But one thing that I think is gonna be really good is, um, you know, after the sessions and you know, I’ve been talking a lot.

With my clients about, um, leading edge erosion. People are now aware that it’s coming. I think the most important thing is to plan for it. It’s not right to get to the point where you’ve got half a dozen blades with, you know, just the full leading edge, just fully missing holes through your laminate, and then your rest of your blades have all got laminate damage.

That’s not the time to start thinking about it because one, it’s a lot more expensive for each repair than it would’ve been, but also. No one’s got the budget to, to get through all of that in one season. So I do really [00:13:00] like that, you know, some of the sites that have been operating for five years or so are starting to see pitting.

They can start to plan that into their budget now and have a strategy for how they’re going to approach it. Um, yeah. And hopefully avoid getting over to the point where they’ve missing just the full leading edge of some of their blades. Yeah. But to Morton’s earlier point, I think it’s also important for people to stop the damage once it happens too.

If, if it’s something that. You get a site or for what, whatever reason, half of your site does look like terrible and there’s holes in the blade and stuff. You need to, you need to patch it up in some sort of way and not just wait for the perfect product to come along to, to help you with that. Some of the hot topics this week were the handover.

From, uh, development into production and the lack of documentation during the transfer. Uh, the discussion from Tilt was that you need to make sure it is all there, uh, because once you sign off. You probably can’t go back and get it. And [00:14:00] some of the frustration around that and the, the amount of data flow from the full service provider to the operator seemed to be a, a really hot topic.

And, and, uh, we did a little, uh, surveyed a about that. Just the amount of, um, I don’t know how to describe it. I mean, it was bordering on anger maybe is a way. Describe it. Uh, that they feel that operators feel like they don’t have enough insight to run the turbines and the operations as well as they can, and that they should have more insight into what they have operating and why it is not operat.

A certain way or where did the blades come from? Are there issues with those blades? Just the transparency WA was lacking. And we had Dan Meyer, who is from the States, he’s from Colorado, he was an xge person talking about contracts, uh, the turbine supply agreement and what should be in there, the full service [00:15:00] agreement, what should be in there.

Those are very interesting. I thought a lot of, uh, operators are very attentive to that, just to give themselves an advantage of what you can. Put on paper to help yourself out and what you should think about. And if you have a existing wind farm from a certain OEM and you’re gonna buy another wind farm from ’em, you ought to be taking the lessons learned.

And I, I thought that was a, a very important discussion. The second one was on repairs. And what you see from the field, and I know Yolanda’s been looking at a lot of repairs. Well, all of you have been looking at repairs in Australia. What’s your feeling on sort of the repairs and the quality of repairs and the amount of data that comes along with it?

Are we at a place that we should be, or do we need a little more detail as to what’s happening out there? It’s one of the big challenges with the full service agreements is that, you know, if everything’s running smoothly, then repairs are getting done, but the information isn’t. Usually getting passed on.

And so it’s seems fine and it seems like really good actually. Probably if you’re an [00:16:00] asset manager and everything’s just being repaired without you ever knowing about it, perfect. But then at some point when something does happen, you’ve got no history and especially like even before handover. You need to know all of the repairs that have happened for, you know, for or exchanges for any components because you know, you’re worried about, um, serial defects, for example.

You need every single one. ’cause the threshold is quite high to, you know, ever reach a serial defect. So you wanna know if there were five before there was a handover. Include that in your population. Um, yeah, so that’s probably the biggest problem with repairs is that they’re just not being. Um, the reports aren’t being handed over.

You know, one of the things that Jeremy Hanks from C-I-C-N-D-T, and he’s an NDT expert and has, has seen about everything was saying, is that you really need to understand what’s happening deep inside the blade, particularly for inserts or, uh, at the root, uh, even up in, with some, some Cory interactions happening or splicing that It’s hard to [00:17:00] see that hard to just take a drone inspection and go, okay, I know what’s happening.

You need a little more technology in there at times, especially if you have a serial defect. Why do you have a serial defect? Do you need to be, uh, uh, scanning the, the blade a little more deeply, which hasn’t really happened too much in Australia, and I think there’s some issues I’ve seen where it may come into use.

Yeah, I think it, it, it’ll be coming soon. I know some people are bringing stuff in. I’ve got emails sitting in my inbox I need to chase up, but I’m, I’m really going to, to get more into that. Yeah. And John Zalar brought up a very similar, uh, note during his presentation. Go visit your turbines. Yeah, several people said that.

Um, actually Liz said that too. Love it. And, um, let’s this, yeah, you just gotta go have a look. Oh, Barend, I think said bar said it too. Go on site. Have a look at the lunchroom. If the lunch room’s tidy, then you know, win turbine’s gonna be tidy too. And I don’t know about that ’cause I’ve seen some tidy lunchroom that were associated with some, you know, uh, less well performing assets, but it’s, you know, it’s [00:18:00] a good start.

What are we gonna hope for in 2027? What should we. Be talking about it. What do you think we’ll be talking about a year from now? Well, a few people, quite a few people mentioned to me that they were here, they’re new in the industry, and they heard this was the event to go to. Um, and so I, I was always asking them was it okay?

’cause we pitch it quite technical and I definitely don’t wanna reduce. How technical it is. One thing I thought of was maybe we start with a two to five minute introduction, maybe prerecorded about the, the topic, just to know, like for example, um, we had some sessions on rotating equipment. Um, I’m a Blades person.

I don’t know that much about rotating equipment, so maybe, you know, we just explain this is where the pitch bearings are. They do this and you know, there’s the main bearing and it, you know, it does this and just a few minutes like that to orient people. Think that could be good. Last, uh, this year we did a, a masterclass on lightning, a half day masterclass.

Maybe we change that topic every year. Maybe next year it’s blade design, [00:19:00] certification, manufacturing. Um, and then, you know, the next year, whatever, open to suggestions. I mean, in general, we’re open to suggestions, right? Like people write in and, and tell us what you’d wanna see. Um, absolutely. I think we could focus more on technologies might be an, an area like.

It’s a bit, it’s a bit hard ’cause it gets salesy, but Yeah. I think one thing that could actually be interesting and that, uh, there was one guy came up with an older turbine on the LPS system. Mm. Where he wanted to look for a solution and some of the wind farms are getting older and it’s older technology.

So maybe having some, uh, uh, some sessions on that. Because the older turbines, they are vastly different from what we, what we see in the majority with wind farms today. But the maintenance of those are just as important. And if you do that correctly, they’re much easier to lifetime extent than it will likely be for some of the nuance.

But, you know, let. Knock on wood. Um, but, but I think that’s something that could be really interesting and really relevant for the industry and something [00:20:00] that we don’t talk enough about. Yeah. Yeah, that’s true because I, I’m working on a lot of old wind turbines now, and that has been, um, quite a challenge for me because they’re design and built in a way that’s quite different to when, you know, I was poking, designing and building, uh, wind turbine components.

So that’s a good one. Other people mentioned end of life. Mm-hmm. Not just like end of life, like the life is over, but how do you decide when the life end of life is going to be? ’cause you know, like you have a planned life and then you might like to extend, but then you discover you’ve got a serial issue.

Are you gonna fix it? Or you know, how are you gonna fix it? Those are all very interesting questions that, um, can occur. And then also, yeah, what to do with the. The stuff at the end of the Wind Farm lifetime, we could make a half day around those kinds of sessions. I think recycling could actually be good to, to also touch upon and, and I think, yeah, Australia is more on the front of that because of, of your high focus on, on nature and sustainability.

So looking at, well, what do we do with these blades? Or what do we do with the towers of foundation once, uh, [00:21:00] once we do need to decommission them, you know, what is, what are we going to do in Australia about that? Or what is Australia going to do about that? But, you know, what can we bring to the, to the table that that can help drive that discussion?

I think maybe too, helping people sort of templates for their formats on, on how to successfully shadow, monitor, maybe showing them a bit mute, more of, uh. Like cases and stuff, so to get them going a bit more. ’cause we heard a lot of people too say, oh, we’re, we’re teetering on whether we should self operate or whether we continue our FSA, but we, we we’re kind of, we don’t know what we’re doing.

Yeah. In, in not those words. Right. But just providing a bit more of a guidance too. On that side, we say shadow monitoring and I think we all know what it means. If you’ve seen it done, if you haven’t seen it done before. It seems daunting. Mm-hmm. What do you mean shadow monitoring? You mean you got a crack into the SCADA system?

Does that mean I’ve gotta, uh, put CMS out there? Do I do, do I have to be out [00:22:00] on site all the time? The answer that is no to all of those. But there are some fundamental things you do need to do to get to the shadow monitoring that feels good. And the easy one is if there’s drone inspections happening because your FSA, you find out who’s doing the drone inspections and you pay ’em for a second set of drone inspections, just so you have a validation of it, you can see it.

Those are really inexpensive ways to shadow monitor. Uh, but I, I do think we say a lot of terms like that in Australia because we’ve seen it done elsewhere that. Doesn’t really translate. And I, if I, I’m always kind of looking at Rosemary, like, does it, this make sense? What I’m saying makes sense, Rosemary, because it’s hard to tell because so many operators are in sort of a building mode.

I, I see it as. When I talked to them a few years ago, they’re completely FSA, they had really small staffs. Now the staffs are growing much larger, which makes me feel like they’re gonna transition out an FSA. Do we need to provide a little more, uh, insight into how that is done deeper. [00:23:00] Like, these are the tools you, you will need.

This is the kind of people you need to have on staff. This is how you’re gonna organize it, and this is the re these are the resources that you should go after. Mm. Does that make a little si more sense? Yeah. That might be a good. Uh, idea for getting somebody who’s, you know, working for a company that is shadow monitoring overseas and bring them in and they can talk through what that, what that means exactly.

And that goes back to the discussion we were having earlier today by having operators talk about how they’re running their operations. Mm. And I know the last year we tried to have everybody do that and, and they were standoffish. I get it. Because you don’t want to disclose things that your company doesn’t want out in public.

And year two, it felt like there’s a little more. Openness about that. Yeah, there was a few people were quite open about, um, yeah, talking about challenges and some successes as well. I think we’ll have more successes next year ’cause we’ve got more, more things going on. But yeah, definitely would encourage any operators to think about what’s a you A case study that you could give about?

Yeah, it could just be a problem that’s unsolved and I bet you’ll find people that wanna help you [00:24:00] solve that problem. Or it could be something that you struggled with and then you’re doing a better job and Yeah, I mean the. Some operators think that they’re in competition with each other and some think that they’re not really, and the answer is somewhere, somewhere in the middle.

There are, you know, some at least small amounts of competition. But, you know, I just, I just really think that. We’re fighting against each other, trying to win within the wind industry. Then, you know, in 10, 20 years time, especially in Australia, there won’t be any new wind. It’ll just be wind and solar everywhere and, and the energy transition stalled because everyone knows that’s not gonna get us all the way to, you know, a hundred percent renewables.

So, um, I do think that we need to, first of all, fight for wind energy to improve. The status quo is not good enough to take us through the next 20 years. So we do need to collaborate to get better. And then, yeah, I don’t know, once we’re, once we’re one, wind has won, then we can go back to fighting amongst ourselves, I guess.

Is Australia that [00:25:00] laboratory? Yeah, I think I, I say it all the time. I think Australia is the perfect place because I, I do think we’re a little bit more naturally collaborative. For some reason, I don’t know why, it’s not really like a, a cultural thing, but seems to be the case in Australian wind. Um, and also our, our problems are harder than, uh, than what’s being faced elsewhere.

I mean, America has some specific problems right now that are, you know, worse, but in general, operating environment is very harsh Here. We’re so spread out. Everything is so expensive. Cranes are so expensive. Repairs are so expensive. Spares spare. Yeah, spares are crazy expensive. You know, I look every now and then and do reports for people about, you know, what, what’s the average cost for and times for repairs and you know, you get an American values and it’s like, okay, well at a minimum times by five Australia and you know, so.

It, there’s a lot more bang for buck. And the other thing is we just do not have enough, um, enough people, enough. Uh, we’ve got some really smart people. We need a lot more [00:26:00] people that are as smart as that. And you can’t just get that immediately. Like there has been a lot of good transfer over from related industries.

A lot of people that spoke so that, you know, they used to work for thermal power plants and, um, railway, a guy that spoke to a guy had come in from railway. Um. That’s, that’s really good. But it will take some years to get them up to speed. And so in the meantime, we just need to use technology as much as we can to be able to, you know, make the people that good people that we do have, you know, make them go a lot further, um, increase what they can do.

’cause yeah, I don’t think there’s a single, um, asset owner where they couldn’t, you know, double the number of asset managers they had and, you know, ev everyone could use twice as many I think. Yeah, I agree. Yeah. I think something that we really focused on this year is kind of removing the stones that are in people’s path or like helping at least like to, to say like, don’t trip over there.

Don’t trip over here. And I think part of that, like, like you mentioned, is that. [00:27:00] The, the collaborative manner that everyone seemed to have and just, I think 50% of our time that we were in those rooms was just people asking questions to experts, to anybody they really wanted to. Um, and it, it just, everybody getting the same answers, which is really just a really different way to, to do things, I think.

But more than, I mean, we, we we’re still. We’re still struggling with quality in Australia. That’s still a major issue on, on a lot of the components. So until we have that solved, we don’t really know how much of an influence the other factors they really have because it just overshadows everything. And yes, it will be accelerated by extreme weather conditions, but.

What will, how will it work if, if the components are actually fit, uh, fit for purpose in the sense that we don’t have wrinkles in the laminates, that we don’t have, uh, bond lines that are detaching. Mm-hmm. Maybe some of it is because of, uh, mango size hails hitting the blades. Maybe it’s because of extreme temperatures.

Maybe it’s [00:28:00] because of, uh, uh, yeah. At extreme topography, you know, creating, uh, wind conditions that the blades are not designed for. We don’t really know that. We don’t really know for sure. Uh, we just assume, um, Australia has some problems with, not problems, but some challenges with remoteness. We don’t, with, uh, with getting new, new spares that much is absolutely true.

We can’t do anything about that. We just have to, uh, find a way to, to mitigate that. Mm-hmm. But I think we should really be focused on getting quality, uh, getting the quality in, in order. You know, one thing that’s interesting about that, um, so yeah, Australia should be focused more on quality than anybody else, but in, in, in the industry, yeah.

Uh, entire world should be more focused on quality, but also Australia. Yeah. But Australia, probably more than anyone considering how hard it is to, you know, make up for poor quality here. Um. At the same time, Australia for some reason, loves to be the first one with a new technology, loves to have the biggest [00:29:00] turbine.

Um, and the, the latest thing and the newest thing, and I thought it was interesting. I mean, this was operations and maintenance, um, conference, so not really talking about new designs and manufacturing too much, but at least three or four people said, uh. Uh, I would be using less carbon fiber in blades. I would not be, not be going bigger and bigger and bigger.

If I was buying turbines for a new wind farm, I would have, you know, small glass blades and just more of them. So I think that that was really interesting to hear. So many people say it, and I wasn’t even one of them, even though, you know, I would definitely. Say that. I mean, you know, in terms of business, I guess it’s really good to get a lot of, a lot of big blades, but, um, because they just, people, I don’t think people understand that, that bigger blades just have dramatically more quality problems than the smaller ones.

Um, were really kind of exceeded the sweet spot for the current manufacturing methods and materials. I don’t know if you would agree, but it’s, it’s. Possible, but [00:30:00] it’s, it, you know, it’s not like a blade that’s twice as long, doesn’t have twice as many defects. It probably has a hundred times as many defects.

It’s just, uh, it’s really, really challenging to make those big blades, high quality, and no one is doing it all that well right now. I would, however, I got an interesting hypothetical and they’re. Congrats to her for, for putting out that out. But there was an operator that said to me at the conference, so what would you choose hypothetically?

A 70 meter glass fiber blade or a 50 meter carbon fiber blade, so a blade with carbon fiber reinforcement. And I did have to think quite a while about it because there was, it was she say, longer blades, more problems, but carbon blade. Also a lot of new problems. So, so what is it? So I, I ended up saying, well, glass fiber, I would probably go for a longer glass fiber blade, even though it will have some, some different challenges.

It’s easier to repair. Yeah, that’s true. So we can overcome some of the challenges that are, we can also repair carbon. We have done it in air, air, uh, aeronautics for many, many years. But wind is a different beast because we don’t have, uh, [00:31:00] perfect laboratory conditions to repair in. So that would just be a, a really extreme challenge.

So that’s, that’s why I, I would have gone for carbon if, for glass fiber, if, if I, if I could in that hypothe hypothetical. Also makes more energy, the 70 meter compared to it’s a win-win situation.

Well, it’s great to see all of you. Australia. I thought it was a really good conference. And thanks to all our sponsors, uh, til being the primary sponsor for this conference. Uh, we are starting to ramp up for 2027. Hopefully all of you can attend next year. And, uh, Rosie, it’s good to see you in person. Oh, it’s, uh, it’s, it’s exciting when we are actually on the same continent.

Uh, it doesn’t happen very often. And Morton, it’s great to see you too, Yolanda. I see you every day pretty much. So she’s part of our team, so I, it’s great to see you out. This is actually the first time, me and Rosie, we have seen each other. We’ve, we’ve known each other for years. Yeah. Yeah. The first time we actually, uh, been, been, yeah.

Within, uh, yeah. [00:32:00] Same room. Yep. And same continent. Yeah. Yeah. So that’s been awesome. And also it’s my first time meeting Yolanda in person too. So yeah, that’s our first time. And same. So thanks so much for everybody that attended, uh, woma 2026. We’ll see you at Woma 2027 and uh, check us out next week for the Uptime Wind Energy Podcast.

What Can Stop Climate Change?

Published

on

I looked through a few of the many thousands of responses to the question above on social media and have concluded:

If you ask uneducated people who know essentially nothing about global warming, you’ll find that nothing can stop it, because it’s been going on since the origin of the planet. Others say that God controls the planet’s temperature.

If you ask climate scientists who work in laboratories around the globe who have been studying this subject for decades, you’ll find that there are two key answers: a) decarbonization of our transportation and energy sectors and b) halting the destruction of our rain forests.

As always, we have a choice to make: ignorance or science.
