Electric Boats To Jumpstart Japan’s Floating Offshore Wind Industry
A fleet of electric boats could build new floating offshore wind farms in Japan that deploy new cost-cutting tensile leg platform technology, eventually.

March 2011—when the Tōhoku earthquake and tsunami devastated four reactors and endangered two others at Fukushima 1—forced a radical rethinking of Japan’s energy picture that continues today with a Japan feed-in tariff program. In the latest round, the utilities are pushing back against the feed-in tariffs and the fruitful development … [continued]
Offshore wind turbines are placed to take advantage of strong, steady coastal winds. Their placement is in one way ideal – dependable energy, and lots of it – but it’s also not exactly easy to build a turbine tower in several feet of moving water.
To tow the new gigantic off-shore wind turbines being developed in Europe far out to sea, a Norwegian company has devised a clever and simple mechanism. Their Windflip tows the turbine out almost horizontal – and then when it gets to the site tilts it up into position; using just the weight of seawater.
The structure contains 29 air filled compartments. Once at the site each of the compartments inside the Windflip is sequentially filled with water, causing the stern to slowly submerge, so that both the Windflip barge and the turbine it is holding flip up 90°.
Not content with dominating the European off-shore renewable energy industry, European juggernauts of offshore wind have landed on the shores of Maine where they want to see if the US is good at making off-shore wind power too. Norway’s Statoil, maker of the Hywind floating wind turbine in Europe (last … [continued]
Floating wind turbines are a little more complicated and require higher initial costs. But a new study, Project Deepwater, by the Energy Technologies Institute (ETI) in the UK has found that due to their greater ability to access stronger and more consistent winds deeper out at sea, they are more economically … [continued]
