I work in the offshorebwind industry, and have been doing so for more than 15 years overseas. I am not directly associated with the offshore wind farm in the illawara, nor the ones near Newcastle.
Happy to answer any questions or discuss concerns to the extend I am knowledgeable, as long as we keep it friendly.
Interesting to have your view on things. The thread here is, let us say, wide ranging.
My start position is that any new technology takes time to be sorted. EVs are a case in point. With offshore wind farms I don't know whether they still qualify as an infant technology or not. I seem to remember that some of the early ones are being retired? Is that more to do with the maritime environment or is it just what they do?
I see no point in arguing about climate change. The insurance underwriters have already factored it into their premiums. We could argue that they are just going with peoples beliefs. But more likely as world populations grow, our exposure as humans also grows. Although we do have more data than any time in history, so we should be able to dodge those bullets.
So a question then is once say wind turbines are set off shore, is that a situation we can retrieve at reasonable cost if later we come up with better solutions for our energy. We have to anyway because there are more of us and we run on electricity.
It the above seems like a ramble, it is because it is a ramble. There are no definite answers, just uncertainty to manage.
Going back to off shore wind turbines, that management includes I would think of whole of life costing. Including decommissioning. The offshore oil and gas industry would have a lot of experience on which we can draw?
yeah, I ll leave the wide ranging discussion to others. Happy to answer your question,
Offshore wind turbines aren't really an infant technology in the global context. In the early 2000's it was new and the turbines back then were designed for a lifetime of 20 years. Nowadays, turbines are designed for 30 years or more. It s an engineering (and economic) trade off.
Developers are obliged to address the decommissioning phase in their plans and economics. Indeed, it draws on the exprience in the oil and gas industry and the offshore wind industry itself. In many countries, everything above the seabed + the burried cabling needs to be removed at expiration of the license/permit. That's certainly possible and the projects would, towards the later phase in the operational life, be obliged to reserve the funds to perform that work when the operational phase ends.

Thank you for the reply. The engineering economics is something of a quiet achiever.

That's true, there is little chance of runaway climate change turning the Earth into a barren rock supporting no life. But what about the environment our great-grandchildren will be faced with?
So let's look at all the angles, not just climate change which is a consequence of the post-industrial age era. People at all levels of society are heavy consumers and we are a throw away society. Think about the resources we use and the quantity of waste we produce. In the 1970's it was all about pollution and that problem has not left us either. The list is a long one if you want to identify all the areas we need to address for our future generations. My answer is that we should all identify as cats so that we can assume an attitude that we don't care, while other people dance around to please our every whim.

...but does this really address the original issue? Should an area used by a small minority group of people be taken over by the demands of a larger organisation?
I see a lot of pungent hypocrisy, not by the people on this site, but by the virtue hungry elite who in one breath say that the colonisation of Australia invaded Aboriginal lands, while at the same time feel it is their right to take places used by groups of people they deem as insignificant.

Takes alot of crap to make more crap.
That's why batteries are an interim solution. The future will be with green hydrogen. The problem with hydrogen in the past has been the energy required to produce it. With renewable energy production having become relatively cheap this problem has been pretty much solved.
The other issue with hydrogen is how unstable it is at normal temperatures. This problem has now been solved as well...
Hydrogenious LOHC Technologies in Germany has developed a method were hydrogen is bound to an oil carrier making it stable at normal temperatures. To split the two the mixture is heated to 400 degrees. The oil is captured and reused. The hydrogen can be used in either a modified combustion engine or power plant.
Problem with green hydrogen is conversion loss.
Take a look at the hydrogen ladder by Liebreich.

This model has been discredited by a number of scientists on several levels. Never mind that Leibreich has major investments in EV charging network provider ChargePoint with hydrogen being a competing solution. His narrative has always been pro EV and against hydrogen based on financial interests rather than scientific facts.

Very wise choice! We don't have to convince residents of Tuvalu that sea levels are rising and climate change is real. Not sure if that's good or not but just some more food for thought for some of the folks here that are still in denial.

Did you actually read the article? The net effect of climate change still impacts the island. The growth is primarily countering erosion but does little for salinity and peak water levels during storms.
Thats always been the case .Alot of uncertainty sea level impacts.Of coarse the Tuvalu prime minister is going to make other claims and hold press conferences in the water ,they need revenue.
I still can't believe someones protesting a wind farm, isn't that like a stop oil protester having a moan at someone with an electric car????

The article was part of a study conducted over just 4 decades. Hardly a solid argument that the world is going to come to an end because of cow fluffs. Four decades ago we had some wicked cyclones that took away beaches, roads and homes on the Gold Coast. Then the climate changed and we did not have a decent cyclone for many years.
I had an article appear in my Chrome feed last night about building wind farms on land and the difficulty of transporting turbine blades on roads due to the length of the blades making it hard to get round bends in the roads.
It seems some bunch of engineers have designed a system to hold the blades on an angle up towards the sky on their transporter truck that reduces the problem. They're going to be using it in Qld for the proposed windfarms on the top of the ranges
I followed back to the source for anybody interested
www.iberdrola.com/innovation/blade-lifter-wind-turbine-blades-transportation
Yes, that is how they transport the blades on I-84 through Oregon. Tip up, very long truck, the blade itself forms part of the trailer.

I can't imagine that wind turbines are dangerous to whales in any circumstance. It is bit like the old argument that daylight saving caused the curtains to fade. There are still the bigger issues to be properly investigated. Are they really needed in the first place or is it just a product of overhyped fear used as a proven way to get a financial benefit. If there is a crisis then we should look at how we have used resources, including energy, since the dawn of the modern industrial age. Plonking a mechanical monstrosity in the ocean is a bandaid solution and it is wrong to justify the alteration of a place purely because of the 'greater good'.

When you look at history, those that love power and control have always used fear as a means of dominating and controlling others, it's no different today, the global elites, The World Economic Forum and the UN are all getting filthy rich from this new green religion, and the mainstream media are fueling the hysteria. Australia produces less than one percent of the world's CO2 emissions and if we want to net zero tomorrow it would make no difference to the global temperatures what so ever. Albanese and Bowen are virtue signalling to the world how great they are for reducing Australia's ridiculously small amount of emissions while sending our economy broke, Labor use to be for the middle to lower class workers but now they have joined up with the greens who demonise fossil fuel and cause the price of everything to go up.
When you the bring the UN into it, you've lost the argument (and your mind)
That article... I think I lost hope. Insane how a small group of people can be formed based on lies, misfear and then start spreading misinformation.
I'll just go windsurfing and suggest those people to find a more meaningful way to spend their time.

As others have noted, you are being misleading. The article clearly says that the sea level is rising and that the outcome of the study "does not negate the need to still vigorously support ongoing mitigation action to curtail future sea level impacts and climatic changes on small island nations."
So you are implying that the study says the opposite of what it actually says. Why did you write a misleading post?

It can be difficult sometimes to extract the meaning of research reports. Not necessarily the one you quote. But as a general case the nuancing in null hypothesising testing can be a trap for even the best minds.
