Hello, I was wondering where the water enters the platoon and How does it remove the water in an equitable manner, avoiding one side from having a heavier weight? Some vertical legs will have a center pipe linking one another, I'm presuming to keep the same weight?
Hello, I am wondering how you built the model. What kid of materials did you use? Did you make the blades yourself? Was the center of gravity similar to real off shore wind turbines?
The platform model was built at the University of Stuttgart/Germany, we used wood as well as carbon fibre as materials for the scaled model. The rotor was built at Politecnico di Milano and the test was conducted in Nantes/France.
Thank you for your comment. We are looking into the matter and will get back to you as soon as we have an answer for you. Best regards The DTU Wind Energy Communications team
Good Day Sir/Madam. I will ask if what kind of materials you used to make this kind of platform? I hope you can response me. We badly need it right now. Thank you so much.

I am currently involved with subsea interconnector cables between countries and have also been involved extensively with offshore turbines ,mainly in export and inter array cables so heres the question as floating wind farms are THE way to go with terra watts potential out there . An export cable will have to come from the individual turbine to the offshore OSS as the voltage produced is AC to be converted to DC in order to " export " to inshore as AC will not be efficient after 50 klm due to the skin effect ,where as DC can go on for ever comparatively. If you bend a copper cable repeatedly it WILL fracture,try getting hold of a length of electrical cable and constantly twist and bend it ,it will break I assure you ,same for aluminium but I doubt they will export the power via aluminium .cores The constant movement of the floating wind turbine will constantly bend the export cable coming from it so how have they over come that problem .
Bigger, better semisubmersibles, capable of supporting all the ganging and conditioning equipment and a vessel that doesn’t jump around in minor waves would work just fine. MPSS is virtually stationary in waves up to 50’ and is predictable and safe over 130’ in tank tests, obviously. The virtual mass combined with the dampened ring pontoon makes it highly stable and capable of supporting well over 20,000 ton, typical big turbine is 3,000 ish. We wouldn’t fatigue the cable, Part of MPSS system is the steel risers in catenary(SCR’S), massive money savers used routinely, also invented by my father as an offshoot of the work done on Apache (reeled pipe), pipelaying ship first of its kind, responsible for about $8 billion in work so far. With the SCR tensioned properly you won’t see a bend and you won’t see fatigue. Some abrasion may occur but we have a proven solution for that also. Offshore wind has chosen to ignore the offshore oil mistakes and it will cost billions before they can turn the juggernaut if they are anything like big oil.
@Will Swift there are plenty of problems here but since this conversation is about cables and bending them a better stable platform is required to counter the constant motions in the oceans. The MPSS (Multi-Purpose Semisubmersible) system, incorporates steel risers held in catenary (SCR’S) invented in the 80s, by my dad as it happens. Now used in place of the flexible high pressure hose (~$10,000/foot last I checked, in the 80s.). Saving nearly as much on the risers as we could on the vessel (~80%). This is a lousy place to discus this so if interested, let’s set up a more suitable media. I’m happy to help. And if you need real solutions we can provide a proven vessel that led the way for almost all semisubmersibles built in the last 20 years.
The offshore oil world avoids this type of vessel by law and experience. Cylinders are not a good solution. If you would like a better solution see Seaways Engineering's MPSS. Big, stable and low cost.
@@qwertyman9560 really? Shell, Exxon, BP, Petrobras and almost all other producers gave up on cylinders years ago. After my Father changed the semisubmersible’s trajectory, making them from mild steel, stiffened plate, just like a ship. look at them now, they all look alike and none have cylinders. Lloyd’s, DNV and ABS all certified our design back in the 80. At that time semisubmersibles we’re almost dead, so many mistakes in the build process, too small, way too expensive and took years to build. BP’s latest semisubmersible, Argos, was going to be a SPAR. They changed course and decided on a copy of our design, saved $13 billion on a $20 billion project because of it. But yeah, cylinders. Floating wind will waste billions and at some point they will “invent” their own semisubmersible based on our work, just like so many others before them.
@@REALITY_ONLY_PLEASE I think you are talking about drilling platforms - which usually tend to be drill ships or Semi submersibles. Yes Spars used to be employed with top tensioned risers, but the trend past couple of decades has been to go subsea with wet trees, which allows production platforms to be the TLPs, Semi submersibles and Spars, which are all essentially cylindrical structures. Examples you may want to check out - Jack St Malo (Semi), Big Foot (TLP), Aasta Hansten (Spar) - all contemporary designs where the columns are cylinders.

No words to explain your hard work, dedication and creativity
How did you build that turbine nacelle and nose cone

what was the arduino used for? nice job
Sorry If the question sounds dumb, but at what faculty o career could belong the facility?
which material is used to make the base for floating wind mill?

Hi Stewart, why are cylinders not so good? What is the technical reason behind it?
Don't know what you are talking about, Spars, semi submersibles and TLPs are all cylindrical structures.
