I’m your host, Allen Hall, and I’m here with Matthew Stead, Yolanda Padron, and Rosemary Barnes. And to lead off this week, s- there’s been some trouble in the North Sea. On July 22nd, a blade failed on one of the turbines at EnBW’s 960-megawatt He Dreiht offshore wind farm. Uh, EnBW spokesperson said there were no injuries, thank goodness, and that the authorities were notified immediately, which is generally the case in Europe. They’re very safety conscious, of course. But the machine was a Vestas V236, which is a– that 15-megawatt offshore turbine that Vestas is offering. And He Dreiht is where the platform [00:01:00] has made its debut. So Vestas and EnBW are working together on an investigation, an RCA, a- along, uh, looking at the environmental impact because parts of the blade landed in the water. And the, the images I saw online were like a sheer web that was being pulled in onto a ship, so big pieces of blade. Uh, there’s gonna be 64 of these turbines going into that wind farm, but this is probably a little bit of a weird thing because it does seem like that the wind farm is under construction when the blade broke, which is not the first time this has happened, right? That we’ve seen blade breaks at, uh, Vineyard Wind and at Dogger Bank on the GE side. Is this just a construction issue, Yolanda, you think? Or is it some sort of, uh, vibration that’s happening during construction that’s putting extra stress on the blades? Yolanda Padron: We were talking about it a little bit offline and how it might be a loading [00:02:00] issue because it’s not, uh, it’s not in the optimal operating, uh, conditions, right? Uh, but this is– It’s– I don’t like that it’s becoming a trend more than an anomaly from what we’ve seen on this podcast. Uh, Matt, I know you work a lot in solutions, right? What, what would you recommend people start doing? Matthew Stead: Yeah. I think, um, more and more there’s ways of just checking out, you know, pre-construction, um, you know, some of the vibration modes, some of the unusual, um, wind loading when it’s in standstill, you know, different yaw angles and so forth. So there, there’s more and more ways of, um, checking out what the blade is doing when it’s in those unusual, um, sort of pre-con, pre-operation phases. So, um, you know, for instance, um, we do know that there is some sort of sometimes edgewise or flatwise vibration, which, um, you know, maybe is not normal, um, and maybe could be, be [00:03:00] thought about in a bit more detail. Um, certainly I know there are some research organizations which are looking into this and also, you know, things like blade twists. Um, so what is actually happening in terms of the, um, the twisting of the blade along, along its axis. Allen Hall: I think the last time this happened, I remember going back and looking at patents about how to protect the blades during this construction phase. So you wanna prevent the blade from generating lift from sideways winds pretty much. So the designs that I saw were like putting like a, a netting across the blade to disrupt the airflow so that it wouldn’t generate lift. But I haven’t really seen that implemented. Maybe it is being implemented, but these loads are a little odd, right? I, I, I’m wondering if there’s any IEC certification test that looks into them, uh, just because it’s, it’s happened a couple of times now, more than a handful. Matthew Stead: We, we saw, um, we saw that picture of some blades on the ground. [00:04:00] You remember they were in storage. Um, there was a, a strong wind that came across them when they were in storage, and there was some, some flutter and, you know, some, some damage it caused, uh, even when they were on the ground. Um, yeah, I think just thinking out loud, you know how on some, you know, wind stacks and, or, you know, turbine stacks and, um, you know, poles, you know, exhaust stacks. Sorry, that’s the word I’m looking for. Exhaust stacks. They have the, the spiral around it. You know, it’s for around vortex shedding. So maybe it’s an opportunity for, for Rosie to ...

  • IWTG Consulting on Pitch Bearing Cracks, Loose Root Inserts

    IWTG Consulting on Pitch Bearing Cracks, Loose Root Inserts

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow Allen Hall: Jon, welcome back to the program. Jon Zalar: Thanks for having me. Allen Hall: Uh, last time I saw you, we were in Melbourne- Yep … at WOMA 2026, and that was a huge event. We know we’re gonna do it again next year in March three, the 3rd through the 5th, so you’re invited back, of course- I can’t wait … if you can make it. Yeah. Yeah. It’s gonna be, it’s gonna be a good time. A lot is happening in the blade world and in the wind turbine world more broadly. A lot of things we’re hearing right now are related to blade bolt connection, pitch bearing inserts still. A lot of that still happening in the United States. What is the current status of, uh, the blade connection issues in the US? I, Jon Zalar: I feel like it’s a growing [00:01:00] issue, not super, super fast, but it seems to be getting a little worse. There’s, you know, more bolts breaking at that joint. Um, pitch bearing cracks are, seem to be pretty common. There’s different solutions for it, and then, you know, the root inserts are another thing that we’ve talked about before that seem to be happening more and more, or maybe more and more people are finding them ’cause they’re looking. Allen Hall: What are the first indications that you have a blade bolt or some sort of joint issue at the root of a blade? What can you see? Jon Zalar: A bolt laying in the hub bouncing around. Um, you know, from like a– looking at it from, like, the sensors on the turbine, it’s really hard to tell unless it gets really bad. Uh, some of the OEMs have some analytics developed to kinda start to indicate if there is a aero change because there’s missing bolts or root inserts are coming out, and they’re using that as a way to go figure out which ones to go inspect first. Allen Hall: Really? Yeah. You think [00:02:00] the SCADA data will give you some indication that you have a, basically a little bit of a loose blade? Jon Zalar: Yeah. I, I, I think because the number of turbines and the number of data points you have, I think there is a pretty good analytic out there right now. Allen Hall: Wow. All right. I think a lot of our operators have not taken advantage of that. Is, is that just b- based on the high-speed data, SCADA data, or is it low-speed data you could see that same effect? Jon Zalar: I believe it’s on the low-speed data as well, but I bet the high-speed data was used to kinda develop it. Allen Hall: Wow. All right. So that’s a huge help to operators. Yeah. So what are you looking for if you’re looking through SCADA data, what would be the couple of markers there that say, “Hey, maybe we ought to go look up at the– in the hub”? Jon Zalar: I don’t know exactly what they’re using, but they would basically look for maybe an imbalance or looking for certain components that are being overworked. Allen Hall: Oh, sure. Okay. Jon Zalar: Yeah. Allen Hall: So your pitch actuator may be getting a little bit overworked. It would seem like one of the places- I think that, yeah … that would get loaded, right? Jon Zalar: Mm-hmm. Allen Hall: Okay. [00:03:00] And any vibration monitoring going on? Because it, it, uh, in some cases you’re– I’m hearing, like, millimeter gaps- Jon Zalar: Correct. Yeah … Allen Hall: between the blade and the pitch bearing. Jon Zalar: So probably a combination of the ALC sensors, at least on a GE turbine, looking at that. But the PCH box also is looking at the tower vibration, so it could be a combination of all three. I don’t know the exact- Okay … details, but between all of that, I think there are some analytics that kinda say, “Hey, go take a look.” And then I think there’s some other companies that have- tools that go monitor it. Allen Hall: Mm-hmm. Jon Zalar: Dial indicators remotely or even, you know, people going up there with dial indicators to go kind of rotate the rotor and kind of see if there is gapping between the blade and the pitch bearing. Allen Hall: Is that a safe situation in your– from the gapping? I’ve heard this where they’ve basically took shims and they’re trying to measure this gap or some sort of dial indication. Is that a smart thing to do? Is it even reliable to do it that way?...

  • Judge Ends Pentagon Wind Freeze, RWE Exits US Offshore

    Judge Ends Pentagon Wind Freeze, RWE Exits US Offshore
    2026/08/10
    Allen covers a judge lifting the Pentagon’s wind freeze, RWE’s $1.22B US offshore exit, and TotalEnergies buying Shell’s European renewables. Sign up now for Uptime Tech News, our weekly newsletter on all things wind technology. This episode is sponsored by Weather Guard Lightning Tech. Learn more about Weather Guard’s StrikeTape Wind Turbine LPS retrofit. Follow the show on YouTube, Linkedin and visit Weather Guard on the web. And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Good Monday everyone. You know … there is an old saying. When one door closes … another one opens. Well this week in wind energy … a whole lot of doors were swinging. Let us start in Washington. For months … the Pentagon had quietly stopped reviewing wind energy project applications. More than a hundred and fifty onshore wind projects … stuck in limbo. The Defense Department claimed that drones in Ukraine had changed the game. Wind turbines … they said … could blind radar to incoming threats. So they hit the brakes. But on Thursday … a federal judge said … not so fast. Judge Karin Immergut … a Trump appointee no less … issued a preliminary injunction. Resume the reviews … she ordered. Follow the law Congress wrote. The law gives the Pentagon seventy-five days for a preliminary review. As of late July … not a single one had been completed since the halt began in May. When government lawyers were asked to name one project they had reviewed … they could not name a single one. The judge told them plainly. If you want to change the rules … go ask Congress. Now … while one arm of the government was being told to do its job … another arm was writing checks. German energy giant RWE … handed back its American offshore wind leases. New York. California. Louisiana. In return … the U.S. Department of the Interior cut RWE a check for one-point-two-two billion dollars. RWE is the fifth developer to walk away from American offshore wind under this administration. The company had spent more than a billion dollars on those leases. Years of planning. Investment. Partnership with federal agencies. But RWE said there is simply no path forward to permit these projects … for the foreseeable future. So where does the $1.22B go? Nine hundred million dollars into Louisiana LNG. Three hundred million into natural gas turbine reservations. Fifteen gas peaking projects across the country. A company that came to America to build wind farms … is now building gas plants instead. But here is the thing about RWE. They are not leaving the wind business. They are leaving American offshore wind. Globally … RWE operates eighteen offshore wind farms. Four more under construction. And nearly seven gigawatts secured in the United Kingdom’s latest auction. America said no. The rest of the world said … come on in. And speaking of Europe … TotalEnergies … the French oil major … just bought Shell’s entire onshore renewables business in Europe. Four gigawatts of solar and wind. Five hundred megawatts already running or under construction in Italy and the Netherlands. Three-and-a-half gigawatts more in the pipeline across Italy … the United Kingdom … and Spain. And in the same breath … TotalEnergies sold a fifty percent stake in a one-point-two gigawatt European portfolio to KKR … for an enterprise value of one-point-eight billion euros. Build it. Sell half. Keep operating it. That is the model. Now let us fly east … to India. GE Vernova just landed a hundred-and-sixty-three megawatt wind order from American developer Enfinity Global. Forty-three turbines. Three-point-eight megawatts each. Headed for the Fatehgarh wind farm in Rajasthan. Deliveries start late this year. And those turbines will be built at GE Vernova’s factory in Pune … which can turn out fifteen hundred megawatts a year. India is pushing for five hundred gigawatts of renewable energy. Meanwhile … up in Denmark … a Danish wind tower maker named Welcon is raising its voice. Swedish utility Vattenfall just won two offshore wind tenders in Denmark. But when asked whether they would use European-made turbines … Vattenfall would not say. Welcon’s chief executive Jens Risvig Pedersen said … and I quote … “It would be completely absurd not to buy European products for the two new Danish offshore wind farms. That would simply shut down the European industry.” The Danish trade union Dansk Metal agreed. Chinese turbines … they said … should not be financed with Danish taxpayer money. Vattenfall says it has not decided yet. But the debate is on. And finally … a milestone that happened so quietly … nobody noticed. The world just crossed three terawatts of installed solar power. It took ten years to build the first terawatt. Less than three years for the second. And not even two more years for the third. Seventy-four countries now...
