thanks, Walt - really interesting webinar - thanks for all the work put in to prepare the material!

Wonderful presentation. I loved how you wrapped up in so little time all the relevant aspects of oWF design. Thanks.

Brilliant and very clear Webinar. Cheers!

Thank you NREL and mr Musial, very informative presentation, looking forward on further improvements. As an offshore surveyor in Brazil, I am aware of the industry's potential and challenges and it's definetly worth it to move towards a diversification of our energy grid, globally. Cheers!

Excellent webinar !! covered in great details

I personally think this video is a very good overview of a floating wind farm. It is so impressive as a person who has worked for the fabrication of a fixed bottom.

Excellent overview of what's happening and of what will be happening!

GREAT INFORMATION WITH MANY THANKS

Excellent presentation! Very excited about the future of the offshore wind industry in North & South America.

great overview - thanks for sharing!

Great overview! Thanks!

Very informative, greatly executed presentation!

This is what is needed on the west coast of Canada where its too deep for traditional pier installations.

Thx for compililng and presenting this information - very interesting and useful.

Beautiful presentation!

Brilliant thank you.

Excellent presentation, very informative.

We just completed the construction of offshore substation for the largest windfarm complex.

If you could get 5 cent electricity into an EV driving at city speeds, it would cost a penny a mile for fuel, while lowering harmful pollution.

Interesting webinar. I was a commercial diver in the Gulf of Mexico for 12 years I have seen many of the same structures in oil platforms. No one is really discussing maintenance and inspection of those structures. On oil platforms divers would inspect the structure using NDT methods. My next big question is what happens to these things during and after a hurricane. I have personally seen, repaired, and salvaged(as a diver) these same structures but bigger crumpled up underwater after Hurricanes Ivan, Katrina, and Rita.

How do you consider the change of wind field over time? The wind speed could drop in the wind farm area over time, right?

Nice video 👍I personnaly think 20MW turbines wil be a thing around 2030-2035. By the way, you said off-shore floating wind turbine could power 2 time the USA ? This number seem very low in comparison to the potential of floating wind turbine imho.

@@marksims5730 15MW? Yikes! I'm familiar with the Principle Power yellow triangle platforms to be used in the eventual Hawaii Offshore Wind Farm www.principlepowerinc.com/ which hopefully will launch in the next decade. Call me a wimpy fraidy cat, but a 15-20 MW turbine on a platform 17 miles from Oahu scares the hell out of me. I see nothing wrong with a Vestas/Siemens/GE turbine of 5-10 MW on these platforms.

Plzz hebuu kuwenii makini kwanini costing iko bei kubwa kisha isijeikakuwa kuna west nyingii

Beginners question: It seems there is a substantial amount of angular momentum in the rotor and mechanicals, but they are sitting 100m above a moving platform. How does the system isolate the rotor from torques from the tower? Is it as "simple" as a gimbal? Even in a storm with large tower excursions (I assume)? Is this a challenge compared to fixed-bottom configurations?

waves are only on the top of the ocean. once you get some weight and depth, you aren't impacted by waves. These guys aren't bouncing around with the waves. There are actually using engineers from oil platforms, and oil platforms have been drilling with pipes down to and actually miles beneath the ocean floor from floating platforms

The extensive cable systems could be a nightmare for whales that would have to navigate through a forest of cables. Vineyard Wind is in a sensitive area. The floating cables would prohibit any commercial fishing and would limit recreational fishing by snagging lines. In addition, the cables on the bottom, that are protected with the barely mentioned "concrete pillow" system; a chain of cable connected large concrete pads will make for miles of anchor snagging, net catching fishing gear nightmare. Will hundreds of square miles have restriction zones where no marine traffic is allowed?

The restrictions on commercial fishing is a very good advantage of offshore wind. Where the windfarms have been installed around the UK have resulted in a massive increase of young fish in these areas. Overfishing is a massive problem wind farms are good for this.

So Sea level has risen by 6 inches in the last hundred years. I don't know whether that's true or not. Even if it is true I haven't noticed because it's such a small change. If we continue to pollute and not change our ways that means sometimes in the year 5920 Los Angeles would have solved their water issue. That also means that the blades will be replaced at least 10x in the next 100 years. These blades aren't reusable nor do they break down. Which means these blades will be with us forever as of right now. Thats more pollution than cow farts. I say let nature deal with co² because it is nature that produced the most co² in the history of man kind. It's funny how we are thought that Venus is so hot because it is 98% co² and that's why the temperature on it is 850° and then we look at earth where it's co² is 0.04% and it's been that way for thousands of years. Maybe the reason why Venus is so much hotter is because it's 38 million miles closer to the sun than we are.

Or are you referring to electricity generated at the wind turbine site? Electrical transmission line losses on land are considered often.

@@shreddagorge The research shows that cats are the No. 1 killer by a long shot, racking in roughly 2.4 billion birds deaths each year. I say ban the cats, deport them to China. But the cats do not kill large birds such as Golden Eagles but wind turbines do. At the infamous Altamont Wind Resource Area alone, more than 2,000 Golden Eagles have been killed by the wind turbines. Also a 2013 study published in The Wildlife Society Bulletin found that wind turbines killed an estimated 573,000 birds annually in the United States. Keep in mind that we have a lot more turbines and they're alot bigger. Also how come this law doesn't apply to the owners of the wind farms? Under the Bald and Golden Eagle Protection Act the first criminal offense is a misdemeanor with a penalty of one year in prison and $100,000 fine for an individual ($200,000 for an organization).
