Vineyard Wind's New "Hybrid" Blade Never Had Torsion Tests

In 2019 a new record-length hybrid blade measuring 107 meters ( 350 feet) was built in Cherbourg France. 
.
The offshore wind turbine blade needed to be tested and certified to produce hundreds of new blades at Vineyard Wind off Nantucket and Dogger Bank, Europe.
.
There was nowhere in the world to test blades this length so a prototype blade was brought to the Massachusetts testing facility which could only test blades up to 90 meters ( 300 feet ).
.
Engineers cut over 50 feet off the blade to get it in the test site and extrapolated the figures. The blade is unlike any other blade because it is a hybrid blade lacking as much carbon fiber as other wind companies.
.
The prototype blade was tested and certified without a torsion test on the entire blade. 
.
Within six months 50 blades were installed with 1 blade failing at Vineyard Wind and 2 at Dogger Bank. Around a six percent failure rate per year.

"The component certification hinged on the testing of two 107m blades produced at our factory in Cherbourg, France. One blade completed its testing at the WTTC test facility in Boston, USA in September."
.
Final test 2019-2020

 "Even in the largest test centers at ORE Catapult, the blade tip had to be cut off to enable the test facility door to close."

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?

We have the facts on our side. We have the truth on our side. All we need now is YOU.
