Vestas V164 80m tubine blade

IW-made blades for world’s most powerful wind turbine start journey

Three cheers for the Isle of Wight and the engineering skills we have within our Island shores.

The Vestas R&D centre in Stag Lane, Newport had a big day on Sunday (8th November) when the first 80m blade – to be fitted to the world’s most powerful wind turbine – left for a journey to Southampton ready for the next leg of its journey.

Long journey for long blades
When all three blade had been gathered – the last of them left the Isle of Wight on 22 November – they made their way to the eventual destination of the Danish national test centre for large wind turbines in Østerild.

The beasts, weighing 35 tonnes a piece and with a diameter, at the root of 4.6m, will be stopping off at Hanstholm in northern Denmark on their way.

When assembled, the rotor diameter of 164m is larger than the London Eye (135m).

The installation of the turbine is slated to be completed in the first quarter of next year.

Update 12.Dec.13: Added date the left IW and added clarity about the journey.

Hehehe!

The title (“most powerful…turbine”) reminds me of an aircraft’s jet engine. I wonder how ‘powerful’ that (turbine) would be if the number of blades were reduced to three?!

What a joke…

Help me understand something- when the 105- ton weightload of the three blades, when idle for lack of wind, do they need an electrical power boost to overcome inertia to get them turning again?

Nice to see we can produce such engineering on the Island.
Even nicer that it’s going to be installed a long way away.

That’s a thought that hadn’t occurred to me Cicero.
Quite possibly I think. But the balance of the blades would be so fine only a battery- pulse would be necessary.
Interesting to know the answer though.

Any wind strong enough to drive the generator will easily pass “inertia”. As an example, just think of the forces to be overcome on a sailing vessel.

Perhaps the Island matelots here comment on whether lateral sailing inertia is similar to circular wind-vane inertia?

“The manufacturers of large turbines — for example, Vestas, GE, and NEG Micon — do not include electricity consumption in the specifications they provide.” Electrical power needed to operate wind turbines. *yaw mechanism (to keep the blade assembly perpendicular to the wind; *blade-pitch control (to keep the rotors spinning at a regular rate) *ights, controllers, communication, sensors, metering, data collection, etc *heating the blades — this may… Read more »

Very interesting ‘Cicero’.

Yes, in order to prevent these super-sized and extra-heavy windmills from stopping too long and distorting (in below electricity-generating wind speeds), there must be an above average need/demand on energy (back out of the grid) to keep them rotating.

Thanks for the link.

It’s like an oil company sponsored gala event in this comments section.

Hehe, yeah.
Only, it’s probably the “oil company” that’s behind those inefficient wind generators.

If white were to erect these things and black to never use wind power, then I’m somewhere in the grey…
