Green Energy Fails Again Offshore Wind Farms Are Sinking
Globally renewable energy has proved to be a very expensive, and unreliable source of power generation, unable to survive without the lifeblood of Green subsidy and backup from power stations on standby for when the wind blows too fast, there is no wind or the turbines freeze solid in winter.
The major problem has been greed, the warmists like to refer to the “dash for gas” when spreading lies about fracking, the so called Greening of energy sources should be called “the dash for Green cash”, because this is exactly what has happened.
The Greens and ecomentalists turned a blind eye to the scam, instead they proclaimed that industry believed in the Green agenda and the CO2 Wolf, when all along it was about grabbing the billions available in Green subsidy as quickly as possible.
The wind turbines in use on both land, and at sea, have a major design problem with the gearboxes and lubricants, to date no gear oil has yet been invented that can stand the pressures in the gearbox.
Even with these known problems we are told that wind will be an important part of our energy makeup:
The foundations of some 1000 Danish offshore wind turbines are crumbling. Denmark faces law suits over the liability and the yet unknown bills for repairs. A large brawl in the wind industry is underway. Serious design flaws in the foundations of some 1000 offshore wind turbines are now leading to lawsuits against and financial losses of several Danish companies. However, there is no overview of the problem, its economic scale and who will have to foot the bill.
The Danes already have the most expensive electricity in Europe due solely to the huge number of wind farms that clutter the country and the enormous Green subsisdies they attract.
The fault was first discovered at the Egmond aan Zee wind farm in the Netherlands and affects those with single cylinder foundations.
Energy company engineers are now urgently investigating what extent the turbines have been destabilised. If repairs are necessary then turbines will be shut down one at a time to prevent energy losses.
Experts from Renewables UK, which represents wind farm developers, said it could cost £50million to fix Britain’s 336 turbines thought to be at risk.
All those billions in Green taxation and they could not even design an ocean resistant foundation, utterly priceless, when you consider the number of structures that have stood for years in the sea without sinking.
According to Recharge – The Global Source For Renewable Energy News the problem is called the scour effect as the picture below illustrates.
A question mark hangs over the long-term stability of Europe’s shallow-water turbines, after research linked to the Horns Rev 1 wind farm found that high-powered currents were causing the stone “armour” around the base of monopile foundations to collapse.
Exposed from behind this layer of shielding stone, turbines could potentially be dangerously destabilised by the effect of scour — the wave- and tide-driven sediment that can eat away at the seabed around fixed structures.
A team from the Technical University of Denmark (DTU) carried out model tests designed to mirror the impact of offshore conditions on the three-layer cover of “scour protection” placed around the 80 turbines at Horns Rev 1, which, three years after installation, had sunk by as much as 1.5 metres.
Experiments in the current flume at the DTU testing facility in Lyngby established that “horseshoe vortices” — twisting flows created by a change in water pressure at the surface of the monopile — were working their way around the stones and carrying off soil from around the foundation, causing the stone armour to sink into the sea floor.
In the dash for Green cash any design was rushed out, just as long as the money could be grabbed and the Green zealots assured that CO2 emissions would be reduced.
No prizes for guessing who will end up paying the bill for sorting this latest Green energy fiasco.
