<p>"The University of Maine at Orono will develop an alternative floating substructure design for a 10–12 MW wind turbine in place of the currently planned two 6-MW turbine floating offshore wind demonstration project planned for deployment off Monhegan Island, Maine."</p>
<p></p>
<p>U-Maine will waste a few million FEDERAL dollars to keep hopes alive of Offshore wind aficionados and pay for propaganda forums (fora?), such as high school students "designing" floating wind turbine contraptions,…</p>

<p>U-Maine will waste a few million FEDERAL dollars to keep hopes alive of Offshore wind aficionados and pay for propaganda forums (fora?), such as high school students "designing" floating wind turbine contraptions, which is off-the-charts nuts.</p>
<p></p>
<p>ANYTHING "OFF MOHEGAN ISLAND" HAS TO BE ABOUT !5 MILES AWAY TO REDUCE LOW FREQUENCY NOISE and adverse visual impacts such as strobe lights.</p>
<p></p>
<p>Here is the Norwegian design. Make sure to watch the videos.</p>

<p><strong>First Commercial Floating Wind Turbine Plant in Scotland</strong></p>
<p> </p>
<p>Hywind Scotland project is the world's first <strong>commercial</strong> wind turbine plant using <a href="https://en.wikipedia.org/wiki/Floating_wind_turbine">floating wind turbines</a>.</p>
<p> </p>
<p>It is located 29 km (EIGHTEEN MILES) off <a href="https://en.wikipedia.org/wiki/Peterhead">Peterhead</a>, <a href="https://en.wikipedia.org/wiki/Scotland">Scotland</a> to minimize visual impacts from shore.</p>
<p>It has five Hywind floating turbines with a total capacity of 30 MW.</p>
<p>It is operated by Hywind (Scotland) Limited, a joint venture of <a href="https://en.wikipedia.org/wiki/Equinor">Equinor</a>, Norway (75%) and <a href="https://en.wikipedia.org/wiki/Masdar">Masdar</a>, Kuwait (25%).</p>
<p><strong> </strong></p>
<p>In 2015, Equinor received permission to install 5 Hywind turbines in Scotland. </p>
<p> </p>
<p>Manufacturing started in 2016 in Spain (wind turbine, rotor), Norway (tower, underwater base, assembly), and Scotland (various parts)</p>
<p>The turnkey capital cost was <strong>$263 million</strong> for five 6 MW turbines, or $8,767/kW.</p>
<p>They were designed to float on the surface, with about 180 m (600 ft) <strong>above</strong> the sea water level and 80 m (265 ft) submerged <strong>below</strong> the seawater level.</p>
<p>Total steel weight is about 2300 metric ton, total ballasted weight is about 20,000 metric ton.</p>
<p><strong>Heavy weights in the bottom of the submerged parts serve to keep them steady and upright.</strong></p>
<p> </p>
<p>The turbines were assembled at <a href="https://en.wikipedia.org/wiki/Stord">Stord</a> in Norway in the summer of 2017, using the specialized <a href="https://en.wikipedia.org/wiki/Saipem_7000">Saipem 7000</a> floating crane, and then towed to the north of Scotland by sea-going tugboats.</p>
<p><strong>Make sure to see the videos showing the crane assembling the entire wind turbine</strong>.</p>
<p>Nothing like that exists in Maine, or in the rest of New England.</p>
<p>That means offshore wind turbine assembly and servicing would largely be performed by foreign companies, which already have built the infrastructures and other facilities during the past 25 years.</p>

<p>The huge, sea-going, specialized, crane (14,000-metric ton lifting capacity) is required for partial assembly on land and final assembly in an area close to shore with a very deep harbor, before towing, fully assembled, to the site.</p>
<p> </p>
<p>The finished turbines were towed to Peterhead, Scotland. <span> </span></p>
<p>Three <a href="https://en.wikipedia.org/wiki/Suction_caisson">cup anchors</a> hold each turbine in place.</p>
<p>About 2400 meter of chain is required, weighing 400 metric ton, for each turbine.</p>
<p>The Hywind Scotland project was commissioned in October 2017.</p> If whales had a vote, they'd…tag:www.windtaskforce.org,2019-10-24:4401701:Comment:1761592019-10-24T03:12:49.738ZKenneth Capronhttps://www.windtaskforce.org/profile/KennethCapron
