Part ownership of a Ripple Wind Turbine, fancy it?

[Mr Gus]

Thing is, helicoptor load lugging is an everyday occurence in the alps during summer renovations, general builds & installs of new / updated lifts, they are very used to it, so with the right experience & drop zone I'm sure this is possible, you hear the coptors zooming up & down the valley every morning .

(of course these are smaller loads & the regular multipurpose rescue copters, but i'm sure you get the point, they transport all sorts beneath them) it really should be a no brainer investment of lift capable kit just like a pilings ship deployed where needed & cost effective to speedy construction.

Someone needs to break the mould.

Incidentally, fire planes (lake scoopers) are being built again for the first time in years, I imagine there was a time when the thought of airborne water scoop & dump was completely alien.

For road accessible the "blade lifter" is a nice bit of kit.. see video

For remote access then surely the new gen airships could be a consideration if the math works favourably?
This video is from when the airlander broke free of its moorings, the computer detected it & brought it in as you see here...

Viable alternate solutions all..

[Mr Gus]

Grouse mountain (blade lift) more than a decade back, so much smaller than now, but the copter is a doozy for lifting "aircrane" series.



The same WT utilised as a visitor attraction (Vanc) @grouse mountain. (internal lift, tight) & rotating platform via the turning of the blades..

Construction & detail as to what was lifted et al..

Solutions therefore already exist, if someone cares to utilise it.

A question on the Ripple/Seedrs community: "Any implications for Ripple re Siemens failure rates?"
https://www.reuters.com/business/energy ... 023-06-28/

LONDON, June 28 (Reuters) - Major wind power developers including Iberdrola (IBE.MC), RWE (RWEG.DE), EDP Renovaveis (EDPR.LS) and Orsted (ORSTED.CO) played down the impact of potential problems with Siemens Gamesa onshore wind turbines.

Siemens Gamesa parent Siemens Energy (ENR1n.DE) last week said problems with its more recent onshore platforms could affect up to 15 to 30% of its installed turbines worldwide, triggering a 37% fall in its share price.

It warned that it could cost more than 1 billion euros ($1.1 billion) to fix flaws in rotor blades and bearings, which could cause damage ranging from small cracks to component failures.

Fingers crosssed...

No, KH turbines are Enercon.

But lets hope they have ironed out some of their historic problems.

Storm winds of more than 100km/hr wrecked the blades? Wow!

A mild Spring morning in Ayrshire!

Ah well, they've had 5 years to improve the design. Just hoping it's not the same batch of past sell by date material as Titan...

I have seen a twin rotor Chinook installing lift pylons on Hintertux Glacier about 25 years ago, they used twin rotor due to height >3000m rather than weight. Helicopters lifting things is common here, snow machines are lifted into place on the mountain in October / November before the natural snow arrives to save on damage to farm land (they take them off with Piste prep machines at end of season while snow is still there. A friend of mine did a Solar installation on a mountain hut a couple of months ago, everything included them was delivered by helicopter which then returned to take them down when the job was done.

Kirk Hill turbines are Enercon E-92 and have a 92m diameter, comprising 45m blade length and a 2m diameter hub.

The weight of a 47m blade is about 12.5 tonne. https://fourearths.com/wind-turbine-bla ... one-weigh/

A Chinook helicopter has a max payload of 10.9 tonne and allowance would need to be made for the weight of the lifting cables, cradle etc.

There are a few helicopters with a higher payload. https://aerocorner.com/blog/heavy-lift-helicopters/

But, I consider the above is sufficient to infer that lifting by helicopter would not be feasible/economic.

[Mr Gus]

What did they do before the specialist offshore turbine ships? ..things evolve, but as for carry weight, they already exist in copter form.

The biggest carrying weight for a copter is in excess of 16 tonnes, (sikorsky ch-53 stallion) as a western made copter.

There is a russian Mil Mi-26 halo that has been kicking around (world sales) for some decades that lifts more..

"As of 2016, the Mi-26 still holds the Fédération Aéronautique Internationale world record for the greatest mass lifted by a helicopter to 2,000 metres (6,562 ft) – 56,768.8 kilograms (125,000 lb) on a flight in 1982.[9]"

Its that hydraulic problem again.

Graig Fatha Status Update

Vensys have emailed to let us know that a hydraulic fault occurred in the turbine at 0826 this morning. The local engineers have been informed and are arranging a visit to look into this further. As soon as we have an update, we will let you know.

I see the above as an improvement in communication and by quite a margin.

[Mr Gus]

How unique is this "hydraulic problem" what was the perceived initial cause, & why is it still happening, design flaw, warranty, general cost per event? all things i'd like to be knowing, as well as when will it cease to be a regular occurence?

How many times now?
