The Aeolus is one of the most advanced offshore wind seejacking vessels in the world. It’s German-built, Dutch owned and operated by the Van Oord offshore enterprise.
The site marinetraffic.com offers the opportunity to follow global shipping. Just register and identify a ship of your choice and from then on you will receive email updates about events concerning that ship, like departure, arrival, berthing. Fortunately have not yet received mails reporting capsizing or sinking.
Yours faithfully has registered as well and chosen the Aeolus. The Aeolus is currently busy constructing the Belgian Norther offshore windfarm, see map below. The Aeolus picks up monopiles, towers, nacelles and rotor blades in Vlissingen, or Flushing as the town is known in Anglosphere (think “Flushing” and “Flushing Meadows tennis tournament“)
Here a summary of the most recent marinetraffic.com mails:
2019-04-21 21:52 – A new photo of AEOLUS has just been uploaded.
The photo shows the Aeolus, carrying 4 wind towers, nacelles and ditto rotor blades, leaving Flushing and heading for the Norther windpark in statu nascendi.

OK, now let’s evaluate this data a little in a back-of-an-envelope calculation. The Aeolus is carrying 4 x 8.4 MW = 33.2 MW worth of nameplate wind power. Total Dutch (still largely fossil-based) power generation capacity = 29 GW. Average Dutch power consumption is 13 GW. How much time does it take for the Aeolus to install 29 GW of offshore windpower in order to complete the intended renewable energy transition?
From the list above you can conclude that the time for a full installation cycle can be 4, 5 or 7 days. Let’s say 6 days. Note that the installation of a complete wind turbines consists of 2 parts: 1. ramming a monopile into the sea bed and 2. placing the wind tower, nacelle and rotorblades on top of the monopile. In other words, it takes 2 x 6 = 12 days to install 4 wind turbines of 8.4 MW each or 33.2 MW in total.
In order to fully replace the total Dutch largely fossil-based power production of 29 GW, that would take 12 x 29,000/33.2 = 10,500 days or 29 years. Mind you, this is nameplate power and a capacity factor of 50% needs to be taken into account. That figure is however offset by the fact that in a couple of years 12-15 MW turbines will be installed, that can be handled by the same Aeolus. So we stick with 29 years. In other words, this single ship Aeolus alone is able to carry out the intended Dutch energy transition until 2050, the planned end date of said transition.
Note that this is a thought experiment. A lot of wind a solar capacity is planned to be installed onshore. On the other hand, as a rule of thumb, for a complete decarbonization of an average advanced western economy you need roughly 2 times the existing power generation capacity to keep the same standard of living, provided you replace conventional heating with heat pumps, implement thorough insulation, drive e-vehicles, etc.
The goal of the exercise is to point out that the renewable energy transition is a realistic enterprise and that the time frame of 2050 is doable.

About the project: predictable strong winds from the Indian Ocean. A lot of social resistance needed to be overcome, tribal quarrels. The Kenyan government not living up to its promise to connect the wind farm to the national grid. Dolleman is an Africa lover, you have to be. He lives there for 40 years now. The plan to build a wind farm is old, but in 2005 it gets contours. With two friends from Holland Harry Wassenaar and Carlo van Wageningen, Wim Dolleman gets enthusiastic support. 300 MW, that would be 20% of the total Kenyan electricity generation. A test period is completed with the conclusion that wind conditions are superb. Most money required is collected from 88 befriended Dutch entrepreneurs, many of whom are in the wind energy business. The World Bank withdraws, and is replaced by the African Development Bank. That was the turning point. The nomads understand that their soil hasn’t been taken away and that their cattle can graze between the turbines.

The construction of the 2 x 700 MW Borssele offshore wind park in the Netherlands off the coast of the Zeeland province, is in full swing, with planned delivery dates 2019 & 2020 resp. Unfortunately no pictures as of yet of the actual wind turbines itself, but instead of the construction of the transformer platform.
The Borssele nuclear power station produces 400 MW. At full wind speed the Borssele wind park will produce 3.5 times as much. Food for thought for the dense “wind energy is not dense enough” crowd.
Lifting capacity: 2000 ton, sufficient for 10 MW turbines.

Average Dutch electricity consumption: 13 GW
The green bars indicate which part of the 2020-target has been realized. The Zeeland province is almost there, Drenthe is lagging behind.
– Offshore windparks Borssele I&II (750 MW) are expected to come online in 2020, Borssele III&IV (750 MW) in 2021.
– Offshore windparks Hollandse Kust Zuid I&II (750 MW) are expected to be completed in 2022.
– After that Hollandse Kust III&IV (750 MW) and Hollandse Kust Noord I&II (750 MW) are next, no closed tenders yet.
– Between 2024-2030 IJmuiden Ver (4 GW) will be next. After 2030, massive expansion further North up until the Doggerbank is definitely an option, enabling the Netherlands to become an energy exporter once again.
By that time storage and energy island will need to be taken into consideration, like a pumped-hydro facility at the Doggerbank and hydrogen electrolysis (cost half a cent per kWh renewable electricity, resulting in a price of stored chemical energy of ca. 6 cent/kWh).
Currently renewable electricity in the Netherlands from solar is 20% of that of wind.

Underwater noise produced by the BLUE Hammer is approximately 20 dB lower than noise produced by conventional hydraulic hammers. Lower noise levels result in lower environmental loads, reducing the costs for noise mitigation and making noise mitigation unnecessary in most conditions.

Royal Dutch Shell says it is considering bidding for rights to develop offshore wind farms in UK waters as the British-Dutch oil and gas giant seeks to re-enter the nation’s sector after a 10-year absence.
Dorine Bosman, Shell’s wind chief, said the company was interested in seabed leases due to be awarded during 2019 by the Crown Estate, which controls Britain’s coast. The Dutch-based firm left the UK offshore wind sector when it sold its stake in the London Array project 10 years ago.
A global pioneer in the field, the UK was one of the key offshore wind markets Shell wanted to enter, she said. The oil major says it is investing US$2 billion a year in developing “new energies” or low-carbon power.
Shell co-owns a minor offshore wind farm in the Netherlands and a larger Dutch project which is under construction. In December it spent US$175 million entering the tiny US market, acquiring the rights to New Jersey and Massachusetts seabed leases that could potentially generate 4.1 gigawatts of wind power.

[english.rvo.nl] – Offshore Wind Energy Roadmap 2030 (2018)
Ministerie van Economische Zaken en Klimaat
Subject: Offshore Wind Energy Roadmap 2030
Dear Madam President,
The Dutch North Sea has the potential to play a significant role in achieving the national contribution to the goals of the Paris climate agreement and the necessary sustainable development of our energy supply towards 2050. A number of crucial steps toward achieving this were set out in the Energy Agreement of 2013.1 The basis for the Netherlands’ long-term energy policy was laid down in the Energy Report,2 the subsequent Energy Dialogue3 and the Energy Agenda.4 In the Coalition Agreement, the Dutch Government will continue to develop that policy and will be actively pursuing the implementation thereof.
The current realisation of offshore wind energy under the Energy Agreement has seen and, until 2023, will continue to see crucial steps being taken for the sustainable development of the Dutch energy supply. The prospect of five calls for tender has given market participants the confidence to invest and has altered risk perception. This has resulted in a major reduction in costs. The Government wishes to retain the market’s confidence and the current momentum and intends to issue the remaining calls for tender for the Energy Agreement within the next two years to complete the Offshore Wind Energy Roadmap 2023.5
At the same time, the national government wishes to take the next step to further develop offshore wind energy for the period 2024 to 2030, and wishes to kick off preparations for this endeavour. To that end, this letter contains the key elements for an Offshore Wind Energy Roadmap for the period 2024 to 2030. In this way, I am honouring the commitment I made to the House during the General Consultation on Energy of 18 January.6
Prof. Gorden Hughes has launched his usual attacks against the wind industry again:
The report’s author, Prof Gordon Hughes, an economist at Edinburgh University and a former energy adviser to the World Bank, discovered that the “load factor” — the efficiency rating of a turbine based on the percentage of electricity it actually produces compared with its theoretical maximum — is reduced from 24 per cent in the first 12 months of operation to just 11 per cent after 15 years.
