Shetland windfarm - Viking Energy

[sheepshagger]

I was referring to the type of installation which has just been deployed in Strandford Loch which is more like a wind turbine with shorter blades which is anchored to the seabed. That's the type of thing which will be deployed in the strong tidal streams around Shetland such as Yell sound and Bluemell Sound where a tidal barrage is impractical.

 

and precisely because the flow is predictable 24 hours a day 7 days a week 52 weeks of the year with no sudden gusts outside its range it will be infinately more reliable than an aero generator, stop reading and repeating propaganda without thinking about the reality of the situation.

like I said if you even had the most basic understanding of engineering principle you wouldn't spout so much turd.

Right, so in your world, machines run forever without ever breaking down. Must be a very special place.

 

And you accuse me of having no idea about engineering principles.

[sheepshagger]

Infinately more reliable was the term I used, that does not mean they will run forever.

It seems your grasp of english is as flawed as your grasp of engineering.

Actually, that's precisely what "Infinately more reliable" does mean.

 

It seems my grasp of the English language is better than yours at least.

And while we're talking about grasping things it should be infinitely and English.

[sheepshagger]

It still does not change the fact that the tidal systems are way more reliable than wind, a constant known input compared to a extremely variable unknown input. You have closed yourself off to this fact because it doesn't fit with your ideal.

your grasp of engineering is seriously lacking, therefor you should qualify all your pleep's with the following disclamer.

 

"It should be noted that AT has absolutely no idea what he's talking about and all information disclosed is for amusement only."

[ArabiaTerra]

Tidal systems may be known and predictable, but they are still variable over the course of the tidal cycle, and this does not change the fact that any tidal generator will require periodic maintenance. It also does not change the fact that the required maintenance will be much more expensive for off shore or submerged systems as it will be for onshore systems such as windmills. It will always be less expensive to send a fitter or a sparky up a wind generator to fix it than it will be to send divers down to a submerged tidal turbine, or to lift the tidal turbine out of the water to fix it. (This also applies to off shore wind generators.)

 

So my argument stands.

I take it you mean less expensive.

Woops, my bad.

Get yourself a quote to hire a 200 foot crane for the day and one to hire a small work boat for a day.

 

Hydraulic jacking with manual back up will raise and lower the whole shebang for a one off installation cost and a small maintenance cost AT.

 

Yes tides vary over the months and years but short of some kind of "space 1999" type catastrophy they will vary within known peramiters, or has one of your climate scientists disproved gravitational theory.

 

you have no grasp of engineering, cost of service, far less reality, stop dribbling pish my lad

where can i sign the sustainable shetland petition , im been awa an dinna ken .

After a dis time listenin tae yun VE nits we could have been weel doon the road by noo to proving how small localised systems could be a success and taken a world lead .

As it is abody is still quabblin aboot whit happens when you dig big hole in peat !!

carbon sinks !! VE Stinks !!!

[Skunnered]

Most local shops have (or had) a petition for people to sign.

Oh tell me about it! I refused to sign the one in the charity shop, and the woman looked at me as if I had just told her that I ate children!

A 200' crane? To do what? I have driven past the Burradale site many times since it was built and quite often seen one or more of the turbines stopped presumably for maintenance/repair and I have never seen a crane anywhere near the site.

 

A more realistic comparison would be : a small work boat plus crew plus divers and equipment, plus tools compared to a transit van with a fitter, sparky and a rigger, plus tools.

 

Sure you can build a hydraulic lifting rig into your tidal turbine, but as you say, this comes at an additional cost which is exactly my point. This system actually has one.

There maybe hsn't been one there recently but I've certainly seen ones in the past.
