Allen Hall: On Wednesday, April 30th at 11:00 AM Eastern, get that on your calendar. SkySpecs, Uptime and PES Wind are hosting our next session of a 10 part series of wind related items on their webinar. So this time it's gonna be about the the biggest challenges facing turbine repair teams today. And we're gonna have four experts besides Joel and me.
I guess we don't count as experts, Joel. So we're gonna be talking to real experts. Sheryl Weinstein from Sky Specs, Alice Lyon from Lyon Technical Access. Craig Guthrie, who I've known forever from Takkion, and Jose Mejia Rodriguez from RNWBL. We'll be there to, uh, explain how you should be planning for this repair season.
What are some of the approaches that the operators use and what works and what doesn't work? Things that if you're in the repair business or if you work. For a large, uh, operator or even a small operator you want to hear and participate in, there'll be a q and a session. So get all your questions ready, but [00:01:00] you first have to register and you can register in the link and the show notes below.
Do not miss this event. April 30th, 11:00 AM Eastern. You won't wanna miss it.

Allen Hall: Up in the Netherlands, three crew members were injured when an offshore support vessel struck a windman foundation. In the North Sea and the Royal Dutch Sea Rescue Society had to evacuate two of the injured crew members from the privately owned vessel. And a third uh, crew member went to get medical attention once they got back to port.
Now, this occurred about 15 miles from the Netherlands shores, and the Dutch have opened an [00:02:00] investigation, and my first responses to reading this news was. How are we driving ships into foundations still? And Joel, can you explain all the technology that is there to prevent you from doing this?
Joel Saxum: Well, every one of these vessels that operates in that environment is going to have a, a helm display, right?
That's gonna have all of the things called stent and aids to navigation. So it's gonna have all the buoys, everything in the water that you could possibly run into. Some of 'em even have detailed stuff like pipeline data and stuff so you don't drop your anchors in certain places. But either way, they're gonna ha they're gonna have knowledge of this besides the fact that you can look out the window and see the tur, see a turbine that's 500 feet tall in front of you.
That's a different story maybe. Um, but a lot of these vessels too, of this size. So this is a, um, a support vessel offshore. So there's all kinds of different classes of boats, things they do. But this thing may work in a wind farm. It may work for oil, uh, platforms, it may work for the fishing industries.
Like it can do a lot of different stuff. But as a, as a [00:03:00] emergency response. Uh, vehicle. They also should be DP one. And when I say DP one, that's dynamic positioning. So that means that you should be able to have a button in the, in the vessel that says, boom, hold me here. And, uh, DP one means you just have one methodology of, of positioning.
So that's like GPS. I'm at this GPS point. Hold me at this GPS point. Um, so there's a lot of safety mechanisms built into these things, and there's a chain of command and all these vessels. I think it said it was crude by eight people. Correct? Correct me if I'm wrong, Alan. That sounds about right. For a hundred, 150, 150 foot operating vessel, eight people's.
About right now, everybody has their own job, right? There's a captain, but there's usually this, you know, a second mate and there's other people on the vessel that someone at all times is looking forward or is supposed to be at least. Uh, but like Phil said earlier today, when we were kind of doing some podcast planning, if you saw the pictures of this thing in port, it looked like it ran square on into the turbine headfirst.
I
Allen Hall: think it was the, uh, [00:04:00] mechanical error or where an operator error just from the damaged photos. I think it's
Joel Saxum: operator error. I think that's someone not chain of command, not paying attention
Phil Totaro: somehow. Well, it's just one of those, the, you know, unfortunate and frankly frustrating things that, and this is, I believe in the last five or six years, the.
Sixth vessel that's run into something like a foundation under construction or an operating wind turbine or something out there. Um, I mean it's happened in Germany and, and now. Here in, in Holland with the, with the Holland Coast, uh, three and four project is my understanding Vattenfall project out there, um, with the Siemens 11 megawatt turbines.
So it's unfortunate that this keeps going down, but I don't know what I mean. To Joel's point, I don't know what more. You could do with technology to warn you that something's out there. 'cause in addition to everything that Joel mentioned, we [00:05:00] also know where the wind turbines are located. There's, there's geo coordinates for all the turbines in the wind farms and there's theoretically some kind of geofencing around the wind farm that tells you, Hey, by the way, you're entering this zone.
Which I mean, as an SOV, presumably you're supposed to be kind of nearby, but. I just don't like, I don't know. I mean, this isn't a technological problem to, to me this is, this keeps sounding like human error. What's the next step?
Joel Saxum: Phil is the next step. We put like a, we put radar on the transition piece with like an audible alarm.
Like when something gets within 500 meters, it just goes. I don't know what else you can do. I mean, they can't see
Phil Totaro: him apparently, so they gotta hear him. Maybe. I don't know. Well, to be clear too, I don't think this was like, uh, you know, a situation where they had fog and or some other kind of obstructed vision.
It was a, to my understanding, it was a reasonably clear day. So I just don't understand how that's gotta be some level of human failure, how you [00:06:00] just smash into a thing that's that big, uh, you know, right in front of you. It's
Joel Saxum: like fog being one thing or like pours visibility. But I'm looking at the picture of this vessel and this vessel has.
A radar on it. It has its own radar, so it's gonna pick it up on the screen next. So no matter what, you should have either been able to look out the window or look at the screen and see the thing in front of you, or look at the GPS coordinates of the, the, you know, problems
Phil Totaro: out there. So, I, I don't know to, to answer Joel's question, I don't think we need more technology, uh, because even though you could, you know, avail yourself of, of radar on every vessel, I mean.
Those that gets expensive and somebody's gotta pay for it. And guess who ends up paying for it? Is, you know, the vessel operator ups their contract. The, you know, project developer has to increase the overall cost of the project and then it takes them longer to, to. Get paid back with the the PPA and or CFDs or whatever other mechanism they have, [00:07:00] and we as electricity rate payers are the ones that end up paying for that at the end of the day.
So I don't, you know, if this is something that can be solved without. Additional technology upgrades. I'm kind of all for that, but something needs to be done as far as like, Hey, there's a big thing like, you know, a few hundred yards right in front of you. Try not to hit it. You know,
Allen Hall: speaking of not running into wind turbine foundations, there's actually an article in PES win, and if you haven't downloaded the latest addition of PES Wind, you can do that on your [email protected].
You just type it into the old Google and. Push the button and there it is. Now, there's a lot of great articles in this quarter's edition and a good bit of offshore in it. The article I wanna highlight today is from Buoyant Works, and if you've been to the Buoyant Works website, you can see all this sort of the polyurethane bumpers that they have created for not only the.
The towers, but also the CTVs, which is really important because they [00:08:00] do run into one another once in a while and it has become more of an issue is that, uh, there's damage on some of these vessels. And just trying to minimize the, the complexity of trying to get close to a turbine without damaging it is, is a huge problem.
And if you have read the article here, and I encourage you to do that on your own. There's a lot going on, uh, as these CTVs approach these turbines and just trying to avoid damage and trying to keep from having bump incidences where the, the crew gets rocked is important here. And Joel, as you have pointed out many times, safety is of the utmost here, uh, on these crew transfer vehicles.
Joel Saxum: Yeah. If you haven't been offshore, there's something to understand, uh,
