\u00ab\u00a0STRUCTURE PORTEUSE D’INSTALLATION DE MODULES DE CAPTAGE D’\u00c9NERGIE \u00c9OLIENNE\u00a0\u00bb<\/h3>

La pr\u00e9sente invention concerne une structure porteuse destin\u00e9e \u00e0 am\u00e9liorer l’implantation des \u00e9oliennes.
Le concept, dans ses diff\u00e9rentes d\u00e9clinaisons, s’applique \u00e0 l’installation d’\u00e9oliennes pos\u00e9es sur le sol, qu’elles soient terrestres ou offshore, ainsi qu’\u00e0 l’installation d’\u00e9oliennes flottantes.<\/p>

D\u00e9clinaison pour les\u00a0\u00e9oliennes flottantes du radier\u00a0HydreManche\u00ae<\/h2>

\u00c9tat actuel des techniques d\u2019implantation<\/h3>

Les \u00e9oliennes offshore flottantes sont install\u00e9es individuellement au moyen de flotteurs et de lests tr\u00e8s importants visant \u00e0 assurer leur verticalit\u00e9 et sont maintenues en position par des ancrages cons\u00e9quents, parfois complexes en fonction de la profondeur du site.<\/p>

En quoi la d\u00e9clinaison \u00ab\u00a0\u00e9oliennes flottantes\u00a0\u00bb est-elle innovante ?<\/h2>

Elle apporte une r\u00e9ponse \u00e0 de nombreuses objections invoqu\u00e9es lors de l’installation d’\u00e9oliennes.
En effet, le radier HydreManche \u00ae peut r\u00e9duire, voire supprimer, les inconv\u00e9nients pr\u00e9cit\u00e9s car il constitue une structure porteuse commune globalement horizontale qui assure le maintien et le positionnement des \u00e9oliennes et qui garantit, lorsqu’elle est souhait\u00e9e, leur verticalit\u00e9.
Chaque \u00e9olienne concourt \u00e0 l’\u00e9quilibre des machines adjacentes, soit par son poids, soit par sa flottabilit\u00e9. Les \u00e9oliennes sont solidaris\u00e9es au reste de la structure porteuse par l’interm\u00e9diaire de liaisons articul\u00e9es ou de syst\u00e8mes formant glissi\u00e8re. Des longrines, longerons ou le cas \u00e9ch\u00e9ant des c\u00e2bles, relient les \u00e9oliennes entre elles, soit \u00e0 des caissons flottants.<\/p>

Si un maintien vertical rigoureux est recherch\u00e9, celui-ci sera assur\u00e9 par l’appui sur une structure porteuse commune.
L\u2019ensemble du radier, sensiblement horizontal est articul\u00e9 de mani\u00e8re \u00e0 s’adapter en pr\u00e9sence de houle. Les longrines reliant les machines entre elles seront compl\u00e9t\u00e9es par des moyens autorisant des oscillations verticales ou des faibles variations de distance entre les diff\u00e9rentes \u00e9oliennes et par des ballasts renfor\u00e7ant la flottabilit\u00e9 et l’horizontalit\u00e9 globale du radier. Elles pourront si n\u00e9cessaire \u00eatre immerg\u00e9es \u00e0 une profondeur adapt\u00e9e au passage de navires au tirant d\u2019eau d\u00e9fini.<\/p>

Les moyens d’amortissement de d\u00e9formation de la structure porteuse ou d’oscillation verticale des \u00e9oliennes flottantes pourront faire l’objet d’une r\u00e9cup\u00e9ration d’\u00e9nergie dite houlomotrice<\/strong> gr\u00e2ce \u00e0 l’exploitation de v\u00e9rins ou de dispositifs \u00e0 transfert de masse.<\/p>

Le cas \u00e9ch\u00e9ant, le radier HydreManche\u00ae, muni ou non de ses \u00e9oliennes, permettra son d\u00e9placement par remorquage vers le site d’installation, puis dans un second temps, l’amarrage ou l\u2019ancrage sur le sol sous-marin.<\/p>

En permettant de mutualiser et d\u2019optimiser le raccordement \u00e9lectrique et l\u2019ancrage des machines, ce proc\u00e9d\u00e9 contribue \u00e0 diminuer l\u2019impact des installations offshores sur l\u2019environnement<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
