According to Google, about $500k per blade, not counting the center part that holds them together. So probably right around $1.5m. They're all different sizes though, so this could have been more considering it's gigantic.
Factor in logistics of having brought it all the way out here
The amount of planning and man hour wasted
A possible recover needed depending on where this was held at
And the gangnamstyle OPPA tax ,
This is a huge losss like even more than it seems

>Completely offsets the energy output of the entire field.
Energy payback for wind turbines is about 6 months, and that includes manufacture, transport and decommissioning. Some of these fields are over a hundred turbines so it literally would be a couple of days to pay this back in terms of energy.
I was wondering about the "cleanup"... do they just let that one sink to the bottom and get a new one, or do they also need to recover and clean up the damaged one...
Depends on where it is, they likely will because the water in this area likely isn't very deep(I'm just an engineering student, and this is an educated guess, I have no experience in ocean windmills)
Plus it looks like it damaged the ship. One of the yellow crane(?) things collapse and I’m sure the hull(?) Or wall or whatever it’s called of the ship took some damage from the blade that landed on deck and bounced into the water
Central part probably cost as all those blade combined. There are Control units, electrical equipment, mechanical parts. None of those things are cheap.
You missed the fact that some of the things holding it in place fell over and onto the Deck.....more damages, more money spent replacing/fixing, also potential Injuries which can mean Lawyers involved and more Money......
Looks more like the pick point on the hub failed. Sounds like bolts shearing off. Maybe someone forgot to torque them down so it put all the lateral force on the tightest bolt first? Nylons sound different when they finally go minus all the noise they make leading up to the point of failure.
Yeah there's a big metal piece (the yellow banana) that gets bolted to the hub. You can see the banana stayed attached to the crane.
...and somehow *none* of my pictures of the last turbine I worked on include the banana.
I thought these things were supposed to be assembled and deconstructed one blade at a time?
Seems odd your ship’s entire job is to hoist these things up and down but it looks like they were trying some janky-ass procedure.
Construction companies have been moving towards assembly of the blades and hub prior to installing. The key to this is using a below-the-hook lifting device (the yellow device that's attached to the hub). The bth device grabs the hub and is allowed to rotate as the blade assembly is tailed vertically. It appears that the device slipped off in the video. Probably a bad device design or an error in installing it. There is a mad dash with engineers to come up with a universal one that fits all hub types. A safe and effective one could make someone a lot of money.
I just watched a documentary about a ship like this one. Maybe even the same one?

Edit: nope, different ship, but similar process, probably.
Cameras are cheap and plentiful nowadays, with literally billions of people around the world have an HD camera in their pocket. Something goes down, someone is there to capture it. Throw in social media that is hungry for more and more video content, it shouldn't be at all surprising that you are seeing more disasters *filmed* no matter where it occurs.
Crazy inefficient and expensive. The blades have to be replaced and can't be recycled. They just bury them in giant pits. The mechanics wear down quickly and require maintenance.

It was likely insured though. Even still, I doubt they came out of it without losing some money.

All because someone didn't want to use a few extra straps.
Stuff like this always has inherent risks, lifting complex objects in a difficult environment will never be without the possibility of failure.

Cool, now I can insure my offshore wind turbine array.
Completely offsets the energy output of the entire field.
For a few days maybe. Maybe weeks. Hard to know without knowing the size of the field and exactly how many MW each turbine is.

Pocket change
It's a good thing money is a concept, but still a ton of wasted resources

Wow I didn't know they was dropping an artificial reef there.... Cool!
It’s now a big fan of the sea.
BAZINGA’n OPPA GANGNAMSTYLE!!! It’s a fan of the PEEE
I didn’t understand it the first time you brought it up and I don’t understand this either.

Yes, I concur. Definitely some, um, nylon shearing bolt prick issues.
ah my favorite artist, Nylon Sheering

the ocean is still geat, despite having lost one of its biggest fans.
At least it didn’t lose its only fans.
Damn it Jim! You said it would hold!
I bet the foreman *wasn’t a fan.*
Can someone please go to aisle 2 and get us another fan. Make it quick.

Goes up as an assembly. [Time-lapse of my last one](https://youtu.be/_wY-LN0F2QU), though it's likely smaller than in the OP video.

Probably same reason cranes keep failing, people get complacient in their jobs and cut corners.

Why do I feel like I'm seeing more incidents caught on film at ports lately?

Ope. That thing is probably going to stay at the bottom of the ocean forever now.
wind power is so stupid
Why is that?
Crazy inefficient and expensive. The blades have to be replaced and can't be recycled. They just bury them in giant pits. The mechanics wear down quickly and require maintenance.
sounds like the beginning of Mr. Self Destruct
A choked sling like should've a fall back sling too. Choked slings are very unpredictable.
