Building Wind Turbines

(Update: I've learned that these thing are supposed to be called wind turbines instead of windmills. So I fixed the title, but I can't take the time needed to fix all of the text.
The photo concerning a boom buggy is now at the beginning of a boom buggy post.)

Building windmills with cranes that have a luffer.

It's now cheaper to build a new wind farm than to keep a coal plant running (This is an interesting milestone considering the design life of a wind turbine is only 10 years. (I've seen since 15 years as a desgin life.))

In the December 2018 newsletter of Midwest Energy, they describe how they put 18 of their road-side spans underground so that "massive cranes" could drive across the road while building a windfarm. The $562m project is being done in two phases south of Colby Kansas: 105 towers will generate 276mw and 72 towers will generate 198mw. That is 2.6mw/turbine for the first phase and 2.75mw/turbine for the second phase. And it is $1.18m construction expense per 1mw of power. To put the 474mw in perspective, coal powered units of 650mw are being shutdown. At least wind turbine farms are getting into the ballpark of coal fired units. T-mobile has signed up for 160mw, Target Stores is buying another 100mw, and the parent company of Jack Daniels is purchasing 30mw.

One option is to lift each blade separately:

Another is to install the blades on the ground and then...

Parker Mims How much sticks that got in it? Around 300' or so?
Shaun DouglasI think 340
Kyle Avinger 0 wind speed @ time of pick?
Shaun Douglas There was always wind. The towers were built with the wind blowing into the face of the tower. The wind always blew the same direction.
Shaun Douglas commented on his posting
All 8 were built facing into the wind.
Update:

Ronald Ritter 1 tower covered by the other.Shaun Douglas Well I was at the top of a tower 2 towers away and that's the best I could get lol
[I could not figure out what was happening until I saw Ronald's comment. It is interesting that the tops of the three towers are in a straight line.]

A video showing a mobile crane instead of a crawler crane being used to erect the windmill. But it is so big that it needs the help of another another crane and truckloads of stuff to build it up for the job. The video uses a "choppy" style, so it was hard for me to understand how it was built.

[This implies the little crane is used to start the tower and probably add the blades to the hub and then the big crane finishes the tower and then adds the nacelle and blade assembly. Moving that big crane from one tower to another would require a very firm, level road. A slight tilt of that long boom would move the high center of gravity too far to the side.]

[Scroll down on the linked page because they have other postings for installing the nacelle and the other two blades.]

I don't like the choppy editing, but I do like the time-lapse scene showing two cranes raising the hub and blades assembly.
Screenshot from Crane Operators of the World 2 posting

"Assembly of a wind turbine on open sea" I don't like the editing because it is too "choppy." And you can mute it without loosing any information. But it is still interesting. From what I can tell, they take the tower pieces and nacelle in one trip and the pre-assembled hub+blades in another trip.

ENERCON E-126 IS THE WORLD’S MOST POWERFUL WIND TURBINE! Enercon E-126 was manufactured by a German company named Enercon and is the most powerful wind turbine in the world. This model has a rotor diameter of 126 m, a a hub height of 135 m, and a height of 198 m. With this, the Enercon E-126 is capable of generating up to 7.58 megawatts of power per turbine. Since its technical revision in 2009, the power output is 7 MW instead of 6 MW.

There are no interior shots, so, after a while, skip to scale comparisons.

Screenshot, unlike American farms, the blades don't turn in phase.

Mike Cline It worked well when introduced. Worked well for about 2 years. 
The wind turbine towers increased in height and turbine a little heavier. Last couple they added counterweight. 
Manitowoc had interest in the states. Almost all the components were to hea
vy to transport. 
Some one why not a lattice. 
Components broke down to 7 or 8 loads. So fewer loads. 
Shows 2 support cranes. Really you only need 1 200 mt class to assemble.

Bill Johns Jr Yeah been there done that. Had to have someone grab my feet and pull me out backwards. Not cool
[
I assume they are doing an inspection. If he's doing just "meat on the hook" work, that is a light load. Since he can keep the boom up, I'm guessing with the light load and small radius that they don't have to add many counterweights, if any. That would significantly speeds up the setup time for the crane. This has to beat climbing the tower and then stringing ropes to hang from to check the blades.]

A few pics from last year's wind farm job in Michigan. 2 18000 Manitowocs. A 12000 set the first 2 tubes, then the 18000 with the luffer set the last tube, generator and then the hub, then the 18000 with the straight boom followed setting the blades.
There are a lot of interesting comments on this post. Too many to copy. But one photo shows an 18000 "catting" across a road. The comments indicate they placed three feet of sand, steel plates, and crane mats on the road before crossing.

Dennis DeBruler I see it is travelling between towers because it is climbing up on some mats. This demonstrates that they travel with the boom lowered. This was my expectation because it lowers the center of gravity and helps balance the full load of counterweights that are on the crane.
Tim Mohr posted
The Necel has been hanging for 2 days today will be 3, haven’t heard what’s wrong just that the crane is broke down.
Tj Keefe What crane is it ?
Had to happen to us with the 16,000 before, except the nacelle was over the top section.

Tim Mohr Lot of big wigs running around so I haven’t gone up there.

[At least this crane failed while the load was still relatively low so it has a lower center of gravity and winds picking up while it is setting dead are not as dangerous. It appears from the photo that a smaller crane builds the hub and blade assembly and then this crane comes in to lift the top tower segment, nacelle, and hub+blades.]

Tim Mohr I was informed that it’s a “Machine head” cause it’s all steel and not fiberglass. Weighs 218,000
Wayland Reece Ledford Probably a DEF issue. It’s stupid to program any machine to go limp or inoperable because of the EPA. Just my thoughts.
Eric Thomas Im surprised cranes don’t have an emergency hydraulic ports for functions in case of engine failure to be plugged into an emergency power unit or some sort where hydraulics can be supplied to release brakes and work functions I’m sure some have a way to do this but I’m not familiar. Anyone know ?
Brian Schenck They do... but it involves bringing in pumps and hoses ,that most places dont have easy access to. Faster to take a few days and get fixed. Had the exact same thing happen a few years back...
AJay White You are not supposed to leave your crane with a load on hook has someone been manning it this whole time.

Give them a warm welcome into your community! Ultimately, you don't want to leave a load on the hook, but if something takes more than a day to bolt up, you don't disconnect.

Chad Mckenney If that is a V-136 tower I believe the necel’s weight close to 380k lbs if not more. That may explain the maxer.
Jason Dick Do any nacelles weigh that much? That kind of weight is goldhoffer and dual lane hauling weight range.
Chad Mckenney Jason Dick when they are shipped into the job they are minus the drive gear and cooling tower. The tops are removed and the sides are extended up two feet.
Chad Mckenney Jason Dick oh and the hubs are flown separate.

LM Wind Power
The 107-meter blade has completed the molding process at our factory in Cherbourg, France....The 107-meter [351'] blade is set to capture the wind for GE’s Haliade-X 12 MW offshore wind turbine, the world’s most powerful wind turbine to date.
[It is the first blade past 100 meters. Is the factory port side so that they can load it directly on a ship?]

(new window) The growth of wind turbines is pushing the heights of cranes, e.g. the Liebherr LTM 1750.



A video passing by 12 of the trucks delivering a MLC650. Since I see a crane by a wind turbine in the background, they are probably building this crane to help build the wind turbine farm.

Including the comments, this post has a few photos showing the entire hub assembly being raised into position.

An 18000 lifting just a hub   The comments indicate that when the blades are too long, e.g. 240', they have to build the rotor in the air because the blades are not strong enough to withstand the forces of using a tailing crane to lift a rotor.
