Let's wait and see how interested industry or the road sector are on any colour hydrogen - once they've all adapted and found ways to use plain old electricity, without needing to use it to complete a heavy and tedious chemical process...
Flour is the solution. It's what is needed and what the world is set up to make lots of. Some people don't like the price of flour so they want to pay to have that flour turned into cake and then have that cake converted back to flour. It's a no brainer. The reality is that the industries which require large amounts of electricity must move their factories to where the electricity is. Trying to ship that electricity across oceans just so the old factory can stay where it is is mental.
I'm not even convinced we should be bothering with paying to keep the Tata steel site in Port Talbot. Not entirely convinced that the argument that a nation must be able to make its own steel is as valid as it was last century.

Generation is still a pipe dream 
What you saw in the gif was all the various vessels activities racing around the site to build it (go look on MarineTraffic.com and zoom in on the area)
Cable layers, rock dumpers, foundation installation, turbines, BOP, commissioning etc
An Armanda
The colour changing of the perimeter, reaching red, shows the waves impacting on any meaningful construction - too hard for the vessels to either / or hold position, be stable to lift or transfer personnel on the 3D walk to work systems or as is usually the case, wave is coupled with wind.
Above 18 or 20ms personnel are not able to work on the whole in the towers. Job stops.
Seems the installation equipment manufacturers haven’t adequately considered that wind farms have to be built in windy locations, therefore the equipment needs to be capable of operating in those same prevailing conditions.What you saw in the gif was all the various vessels activities racing around the site to build it (go look on MarineTraffic.com and zoom in on the area)

Not the case at all.
HSE / regulations for putting personnel in towers (i.e. regulations, not 'equipment')
Any idea how much the towers move 130m in the air?

Turbine manufacturers ……. On a thin ice
The installation progress table in the weekly notices of operations make grim reading for DBA:https://doggerbank.com/document-categories/notices...
As long as 18-19 months and counting for monopile to WTG installation in some cases.
Moray West seem to be flying along in comparison with as little as three months:

how can one area be going smoothly while another so badly? as far as my limited understanding goes, it's not more challenging to install on dogger?
Mildly more challenging, but only with respect to how far away / remote and logistics. Soils, water depths all are within the norm.Piling / foundation installation going great at the moment despite the original vessel planned (Alfalift One) conspicuously absent. The old girl / tonnage of Oleg Strasnov is smashing in three a day !!!
Without a doubt the large proportion of the time is due to the turbine - and manufacturer
They have one other unit, also with issues in the world. Learning on the job. And inherent design flaws
GE are going to hurt from this

I get that it’s easier said than done, but is there anything actually being done to meaningfully improve it?
dvs_dave said:
That’s my point. If the current installation equipment/methodology regularly results in conditions that fall foul of safety regs, then maybe it’s time for a rethink as it’s seemingly not all that compatible with the prevailing site conditions. Improve that and you have safer conditions and fewer delays which is a win all round.

Not allowed up a turbine at all, so construction, finished, operating etc-I get that it’s easier said than done, but is there anything actually being done to meaningfully improve it?
It’s not ‘installation equipment’

So when it’s windy the towers are too flexible to make it possible for men to be up there? Is it work that could be achievable, even partially, with an ROV of some description? It’s not ‘installation equipment’

You are aware that once the vessel approaches with the safety zone, and whilst anyone is in the turbine, it is locked down (ie not making money)

Why would you want to put Techs in a Turbine on a windy (power producing) day.

No I’m not aware. How would I know that? I don’t work in the industry. Ground up/high rises are my field. That’s why I’m asking questions. Although you don’t seem particularly interested in answering them sensibly, so I’ll leave you to it.

Well firstly you blamed ‘installation machinery’ when I’ve indicated it’s not the case, or problem, and I have responded to the questions but you seemed determined to chase a dog that’s not relevant in the discussion in Doggerbanks issues, which I am trying to be sensitive about answering.
I certainly didn’t mention the GE blade that folded in half after 24hrs and fell in to the sea for example.
Drones (aerial) are being looked at, and robots are being trialled for blade repairs and inspection but all rather gimmick than successful

That middle sentence is ominous; was it detected as even a slightly defective blade before installation? Or, in other words, how many of the other blades have big old question marks hovering over them?I certainly didn’t mention the GE blade that folded in half after 24hrs and fell in to the sea for example.
