OK ... I got it now. In the background is an access panel for viewing/inspecting the back-side of the rotor hub. As viewed, it is rotating counter-clockwise. You can see each blade's root attachment bolt circle as they pass (3 blades). I can finally sleep again.
I have worked in the construction of Vestas, GE and Nordex turbines. Vestas lift the drive train into the nacelle after the nacelle is landed on top of the tower, while the drive trains are installed in the GE and Nordex turbines on the ground prior to the lift. Nordex Delta 4000 nacelles are around 140 - 175 tonnes in weight. GE Cypress are circa 130-150 tonnes.

This is a mandatory part of a proof of stability. During Testruns I can hear many Noises and Vibrations which then allows me to gather more information about the condition of many Parts in the Turbine. For example Bearings of Gearbox and Generator, defects on the Pitch System and Blade Bearings, loose or broken Parts inside the Hub, and many more.. Generally there is nobody on the Turbines while in Production. So while doing this we have to follow special Security regulations, which include also pre-preparations for fast evacuation in an Emergency.
@@spacecat7247 Yes there is an emergency hatch in the nacelle, where you attach to a rope and slide down. I'm sure Mr. Wind here can give us a better explanation.
A kettle is common for longer Stays during Maintenance works, a Hammock is easly feasible but really not recommended to sleep inside a (running) windturbine. xD
At the factory, after mating the gearbox/mainshaft, we would attach a temporary motor on the brake coupling "aka shaft going to gen" to turn the whole drive train to pump grease into the shaft and check gearbox vibration. When our tempary test motor broke, we would turn it by hand THAT SUCKED 😅 your talking spinning for minutes to get one full rotation on the main shaft that just tells ya how much more rpm is going to the generator
I am not an expert for this question, but regarding to most studies the energetic amortization of a Windturbine is between 3 months and 3 jears. Whereas modern Turbines are operational for at least 25 to 30 years. So I answer your question with a big yes. Greetins
Good question. I think a "completely honest" assessment including the footprint including the WHOLE chain of fabrication, installing, maintaining AND dismantling would not come to a very pleasing result...
Very nice vid, thank you mate. I may be joining this industry in the next months, the only thing I am worried about is the noise level I will be exposed to. I have a condition for which my right ear is almost deaf, this is why I have to protect the left one at all cost so that I can still hear things decently. Do you think exposure to these machines -wind turbines in general- may harm my hearing? Having to live with the constant stress of volume intensity is a concern to me. Thanks in advance Federico
Don't worry, just stick to the Savety Regularitys regarding Ear Protection, then everything will be just fine. Just trust your sense for harmful Noises, If you got one like me 😁
I flew on Blackhawk helicopters for 4 years. I wore earplugs and the standard flight helmet with earmuffs. 30+ yrs later, I can hear just fine. Do what you love doing. You’ll be happier.
Hallo Bäschers. Wir produzieren auf Arbeit Sensoren für diese Monster. Ich repariere sie, wenn sie Fehler haben. Mit der Montage haben wir ein Glück nichts am Hut. Da hoch steigen wäre nicht meins. Interessant sowas auch mal zu sehen.
1. Weil es im Maschinenhaus keine direkte Absturzgefahr gibt. Zudem ist das oft störend und man bleibt dort oben oft hängen. 2. Das mache ich als Teil einer Inspektion um Mängel zu erkennen, die man erst hören kann, wenn sich der Triebstrang dreht (Lager, Verzahnung, Lose Teile) LG
Vestas schreibt selbst vor, bei arbeiten im Maschinenhaus mit drehenden Teilen soll man seinen Auffanggurt ablegen. Es ist auch so gut wie unmöglich die ganze Zeit im Gurt zu arbeiten.
Highly depending on turbine type, wind conditions on site and many other factors. I dont have experience in those questions, but it may range from 5 to 15 year's. But you have to keep in mind that modern turbines (the ones for the European market) are having a design lifetime of 25 to 30 years and may exceed this time by far.
You are In the Back of an Windturbine, looking towards the Rotor. The Part wich is Moving is the Hub, the Part where the Blades are attached. The Blue, circular thing in the middle is the Gearbox, followed by the Generator, also in Blue on the Left side.

Of course, I've been living there for more than 5 year's. No, Honestly... if it were allowed to, I am sure that only the toughest people would live there just a few days before they resign. It is loud, the Movement is unpredictable for your Brain, inside there is no Window as reference for your sense of balance. You will get a kind of seasickness very soon, even if you are used to.. without Operation, we can talk about 😄
So in this test, the turbine was POWERED up, much like a giant fan, rather than actually spinning from wind power? (I do have to admit, that was a great sound) I love the sound of high inertia machinery starting up.
This would be a funny feature to Power the Turbine up, actually this is theoretical possible, but the System isn't build to do a self Powering at full Power. At some Turbines it is possible to do this self powered Turning, but just at powers of some 100 kW and the only purpose is to go and hold a specified position of the Rotor, for example if you want to set the Rotor lock to gain save access to the Hub. So all Testruns that I upload are under real operating conditions, so just powered by Wind :-)
@@saasch_baasch If you've just serviced the transmission, and there is no wind. To verify proper oil flow and level, it's sometimes necessary, to roll the transmission to distribute the oil, and make sure the filter's full and the level is up. With no wind, the only way to do this, is to power the alternator, temporarily using it as a motor. It's also a way to test the braking mechanism, and other tests, requiring rotation of the rotor.
@@vincentrobinette1507 very interesting, at which types of Turbines are you working? I know the "no Wind Problem" very well. Most of the Turbines are using external Oil Pumps in Combination with mechanical Oil Pumps, or even without them. I know that Siemens DD and the Gamma and Delta Turbines from Nordex can do that. Are there any others? As I said before, this Feature is a special procedure and in addition in rare use for my tasks. 😊
Why do they don’t mount the gearbox and generator on the base of the tower instead of on the nacelle on the top ? Just use and angular gear on the top to transmit the power to the base. Installation and maintenance cost would be half..or less
There are indeed some very old Turbines with this setup (e.g. Voith-Hütter WEC 52). But there are many reasons why manufacturers don't use this design on tall and high power Turbines. 1. Due to modern Pitch systems and greasing (even with a vertical shaft), the servicemen have to enter the Nacelle anyway. 2. Service in Onshore Turbines is cheaper then you think, due to cheap elevators and a crane on every modern Turbine. 3. The dimension of a 150 m long shaft, which is transferring the power without a Gearbox on the Top is insane. The Torque is roughly 1 million Nm per MW rated Power. So at actual Turbines the Shaft have to withstand a Torque of more than 5 MNm at high wind speeds. The Twisting would be very strong! I estimate a diameter of approximately 2 meters of steel. Just imagine the weight on the Axial Bearings. Carbon fiber would be too expensive for that case. Always remember, the price per kWh must be as low as possible. 4. Manufacturers want to have all systems at one place for many reasons, so they are putting all the stuff on one Place. 5. And many many more... This Design may be Possible on modern Turbines, but would create much more costs in the end. Regards 😊
Ich stelle immer wieder erschreckt fest, dass die Anlagen von anderen Herstellern innen echt alt aussehen, verglichen mit NX. Und super laut sind... Bei NX wirkt irgendwie selbst innen alles sauber und durchkonzipiert, wohingegen bei zb. GE Schläuche, Kabel, Filter o.Ä. kreuz und quer herausstehen, im Weg stehen und die Kisten generell sehr zugebastelt wirken.
da gibt es tatächlich eine hohe Variabilität, wobei es auch - kaum zu glauben - wenige Anlagen gibt, die innen sogar noch aufgeräumter als die von Nordex wirken ;) Häufig liegt das daran, dass man anstatt einem Redesign einfach anbaut und vorhandene Kabeltrassen / etc. benutzt, muss ja schließlich nur zwei dinge erfüllen: 1. Güstig 2. es muss funktonieren ;)
Woow no Harnas on? no helmet? no fireproof cloths on with long sleeves? This is a big NONO At Nordex! you will get fired if you walk like this in the Nacelle.
My neighbour a physics lecturer had crunched the numbers and he told me a wind turbine would have to run at 100% output for 25yrs continuously to break even on its carbon footprint. That’s zero maintenance, breakdowns or still air or too fast a wind speed that causes it to stop. It will never happen.
Sorry, but your neighbor had a glitch in the multipliers! Nobody buys a wind turbine cash. And no bank lends money if it is a bad investment. And you described the worst investment possible. So every picture of a turning wind turbine proofs your physics lecturer next door simply wrong.

Wow, you can really see the scale differences to the other turbines on this channel, from small car internal volume to more space than a modest house.
