First Monopiles Installed at Borssele Offshore Wind Project

The Borssele I-V 1.5GW offshore wind project is currently the largest in the world (but not for long). This is Ørsted’s first project in the Dutch part of the North Sea. The first and largest monopile of a weight of 1,188 ton and a length of 76 meter has been rammed into the seabed. Borssele I-II is expected to be operational later this year and will produce sufficient electricity for 1 out of 8 million Dutch households. The 94 monopiles in total will have been installed by April, after which the towers and Siemens-Gamesa turbines can be installed in a couple of months more.

New Aeolus Video

This latest video shows the Aeolus with a new, larger crane, enabling the ship to handle the largest wind turbines to date.

The Aeolus is probably the most advanced offshore wind-turbine installation ship in the world today. German-built, Dutch owned, this ship is able to install a monopile for the latest 10-12 MW wind turbines within 24 hours. If we would add two days for the installation of the tower, nacelle and blades and assume that a simple, much cheaper barge would deliver all these parts at sea, eliminating the need for the expensive Aeolus to fetch these part from the port itself, we arrive at a hypothetical installation capacity of 100 MW per month or 1.2 GW per year. The Netherlands consumes on average 13 GW electricity 24/7/365. That is 11 years installation time. However, even these large turbines have a capacity factor of 60%, so 13 GW real installation (ignoring storage issues), with 6 MW per 10 MW nameplate turbine or 60 MW/month of 720 MW/year, would require 18 years installation time.

Think about it, a single ship is (in theory) able to replace the entire fossil fuel-based power production capacity of a country like the Netherlands, with a population of 17 million, that has the highest electricity consumption per capita in the entire EU, in 18 years time. As a rule of thumb, multiply this with a factor of 2 in order to create a truly renewable energy base, powering everything, including transport and space heating, with heat pumps.

One ship, the Netherlands, 36 years.

Europe has many of the jackup ships.

Do Wind-turbines Kill Birds?

People who oppose wind farms often claim wind turbine blades kill large numbers of birds, often referring to them as “bird choppers”. And claims of dangers to iconic or rare birds, especially raptors, have attracted a lot of attention… Wind turbine blades do indeed kill birds and bats, but their contribution to total bird deaths is extremely low, as these three studies show. A 2009 study using US and European data on bird deaths estimated the number of birds killed per unit of power generated by wind, fossil fuel and nuclear power systems. It concluded, “Wind farms and nuclear power stations are responsible each for between 0.3 and 0.4 fatalities per gigawatt-hour (GWh) of electricity while fossil-fuelled power stations are responsible for about 5.2 fatalities per GWh.“. That’s nearly 15 times more. From this, the author estimated that wind farms killed approximately seven thousand birds in the United States in 2006 but nuclear plants killed about 327,000 and fossil-fuelled power plants 14.5 million. In other words, for every one bird killed by a wind turbine, nuclear and fossil fuel powered plants killed 2,118 birds.

[] – Wind farms are hardly the bird slayers they’re made out to be—here’s why

Seabirds are better at avoiding wind turbines than previously thought. Wind farms are far less harmful to birds that first thought, the biggest ever study has shown, because seabirds actively change their flight path to avoid them. Researchers used radar and video to monitor seabirds flying near the Vattenfall’s Thanet offshore wind farm in the English Channel over a two year period. They found that birds were present near the turbines in just two per cent of the 600,000 videos shot during the period, and they recorded just six collisions – an average of one every four months.

[] – Wind farms less harmful to seabirds than first thought

Many migrating birds have learned to avoid potentially deadly wind turbines, but this behaviour equals a loss of habitat for the animals, researcher Ana Teresa Marques and others write in the Journal of Animal Ecology…Environmental NGO Nabu estimates about 100,000 birds in the country could be killed by rotor blades each year. To put this figure into perspective: Environmental organisation Friends of the Earth Germany (BUND) says that about 18 million birds in Germany die every year by crashing into windows.

Lagerwey L100 – Inside an Efficient Large Wind Turbine

Lagerwey is a grass-roots Dutch wind turbine and tower manufacturer that produces the entire wind turbine chain itself and is around since 1979. Lagerwey has a “special relationship” with Russia in order to get the wind energy revolution off the ground in Russia too by licensing Lagerwey technology to Russian companies.

Offshore Wind: Can the US Catch up with Europe?

[source] The red area between England, Holland, Germany and Denmark is shallow water, where monopiles can be installed and combined with excellent average wind speed, is ideal for wind power.

Key Findings:

 Europe has more than 90 percent of the world’s total installed offshore wind capacity, and will continue to
dominate the offshore wind market for years to come.

 Differing estimates say Europe will have 23.5 – 40 GW of offshore wind by 2020, and 43.8 – 150 GW by 2030.

 The United States is expected to ramp up its deployment of offshore wind—with three gigawatts of offshore wind by 2020, 22 GW by 2030, and 86 GW by 2050—which will spur the development of a U.S. supply chain.

 China, Japan, South Korea, India, and Taiwan all have ambitious offshore wind targets, adding up to 35 GW of new offshore wind capacity by 2020.

 European companies have decades of experience installing offshore wind farms, and stand to gain the most from offshore wind’s global expansion.

The Dutch Energy Transition – Faster Than You Would Expect

Total Dutch average electricity consumption 24/7/365: 13 GW.
Total installed power generation base: 29 GW.
The sport is to replace all remaining fossil capacity with renewable.

The price of a renewable kWh has come down considerably between 2010-2018 and further price erosion is to be expected.

First Time 11 MW Turbines For Subsidy-Free Offshore Windpark

The Netherlands have barely begun to build the largest offshore wind park in the world, Borssele I-V (1.5 GW) and already the next 1.5 GW Mammoth is being planned: “Hollandse Kust Zuid 1 & 2” (“Dutch Coast South 1 & 2”), expected to be operational in 2023, 22 km out of the coast near The Hague.

For the first time, 11 MW Siemens-Gamesa turbines will be installed, 140 of them eventually, to arrive at 1.5 GW.

Between 2025 and 2030 it will be a neck-and-neck race between the Netherlands and the UK about who is the largest installer of new offshore wind capacity, with ca. 2 GW/year each.

The idea behind the self-climbing crane is to eliminate the expensive necessity of bringing a huge crane to the wind turbine construction site and instead to use the wind tower in-build up as its own crane.

Weight crane: 65 ton
Max. load: 60 ton
Buildup time: 1 day

Energy Autonomy for Farmers

Small windmills that are not an insult against the rural landscape. Perfect means to circumvent the NIMBYs, who agitate against large onshore wind farms. Solar panels on large stable roofs and a 20m high wind “tower” in the fields are sufficient to energize the entire farm, provided sufficient storage is in place.

Price: 40,000 euro. Windmills like these have become very popular under farmers, especially in the windy North of the Netherlands, which is no surprise since farmers own fields without wind shadow, unlike private households. From the graph below, annual yield wind ca. 30,000 kWh. With a Dutch kWh-price of 20 cent, the yearly return would be ca. 6,000 euro. Payback time hence 40/6 = 7 years. That’s decent and better than solar, typically nine years for private households, which assumes 100% feed-in tariff, essentially a subsidy that won’t last.

Installed in the right proportion, solar and wind even each other out, so no seasonal storage is necessary. This solution is ideal for farmers in windy NW-Europe, who can achieve real energy autonomy. Biofuel generators can close the last gap.
